New, nature-inspired concepts for turning carbon dioxide into clean fuels

Researchers have developed an efficient concept to turn carbon dioxide into clean, sustainable fuels, without any unwanted by-products or waste.

The researchers, from the University of Cambridge, have previously shown that biological catalysts, or enzymes, can produce fuels cleanly using , but at low efficiency.

Their latest research has improved  production efficiency by 18 times in a laboratory setting, demonstrating that polluting carbon emissions can be turned into green fuels efficiently without any wasted energy. The results are reported in two related papers in Nature Chemistry and Proceedings of the National Academy of Sciences.

Most methods for converting CO2 into fuel also produce unwanted by-products such as hydrogen. Scientists can alter the chemical conditions to minimise hydrogen production, but this also reduces the performance for CO2 conversion: so cleaner fuel can be produced, but at the cost of efficiency.

The Cambridge-developed proof of concept relies on enzymes isolated from bacteria to power the  which convert CO2 into fuel, a process called . Enzymes are more efficient than other catalysts, such as gold, but they are highly sensitive to their local chemical environment. If the local environment isn't exactly right, the enzymes fall apart and the chemical reactions are slow.

The Cambridge researchers, working with a team from the Universidade Nova de Lisboa in Portugal, have developed a method to improve the efficiency of electrolysis by fine-tuning the solution conditions to alter the local environment of the enzymes.

"Enzymes have evolved over millions of years to be extremely efficient and selective, and they're great for fuel-production because there aren't any unwanted by-products," said Dr. Esther Edwardes Moore from Cambridge's Yusuf Hamied Department of Chemistry, first author of the PNAS paper. "However,  sensitivity throws up a different set of challenges. Our method accounts for this sensitivity, so that the local environment is adjusted to match the enzyme's ideal working conditions."

The researchers used computational methods to design a system to improve the electrolysis of CO2. Using the enzyme-based system, the level of fuel production increased by 18 times compared to the current benchmark solution.

To improve the local environment further, the team showed how two enzymes can work together, one producing fuel and the other controlling the environment. They found that by adding another enzyme, it sped up the reactions, both increasing efficiency and reducing unwanted by-products.

"We ended up with just the fuel we wanted, with no side-products and only marginal energy losses, producing clean fuels at maximum efficiency," said Dr. Sam Cobb, first author of the Nature Chemistry paper. "By taking our inspiration from biology, it will help us develop better synthetic  systems, which is what we'll need if we're going to deploy CO2 electrolysis at a large scale."

"Electrolysis has a big part to play in reducing carbon emissions," said Professor Erwin Reisner, who led the research. "Instead of capturing and storing CO2, which is incredibly energy-intensive, we have demonstrated a new concept to capture carbon and make something useful from it in an energy-efficient way."

The researchers say that the secret to more efficient CO2 electrolysis lies in the catalysts. There have been big improvements in the development of synthetic catalysts in recent years, but they still fall short of the enzymes used in this work.

"Once you manage to make better catalysts, many of the problems with CO2 electrolysis just disappear," said Cobb. "We're showing the scientific community that once we can produce catalysts of the future, we'll be able to do away with many of the compromises currently being made, since what we learn from enzymes can be transferred to synthetic catalysts."

"Once we designed the concept, the improvement in performance was startling," said Edwardes Moore. "I was worried we'd spend years trying to understand what was going on at the molecular level, but once we truly appreciated the influence of the local environment, it evolved really quickly."

"In future we want to use what we have learned to tackle some challenging problems that the current state-of-the-art catalysts struggle with, such as using CO2 straight from air as these are conditions where the properties of enzymes as ideal catalysts can really shine," said Cobb.

The almost 11-cm-high Venus figurine from Willendorf (Austria) is one of the most important examples of early art in Europe. It is made of a rock called oolite that is not found in or around Willendorf. A research team led by the anthropologist Gerhard Weber from the University of Vienna and the two geologists Alexander Lukeneder and Mathias Harzhauser as well as the prehistorian Walpurga Antl-Weiser from the Natural History Museum Vienna have now found out with the help of high-resolution tomographic images that the material from which the Venus was carved likely comes from northern Italy. This sheds new light on the remarkable mobility of the first modern humans south and north of the Alps. The results currently appear in Scientific Reports.

The Venus von Willendorf is not only special in terms of its design, but also in terms of its material. While other Venus figures are usually made of ivory or bone, sometimes also of different stones, oolite was used for the Lower Austrian Venus, which is unique for such cult objects. The figurine found in the Wachau in 1908 and on display in the Natural History Museum in Vienna has so far only been examined from the outside. Now, more than 100 years later, anthropologist Gerhard Weber from the University of Vienna has used a new method to examine its interior: micro-computed tomography. During several passes, the scientists obtained images with a resolution of up to 11.5 micrometers—a quality that is otherwise only seen under a microscope. The first insight gained is: "Venus does not look uniform at all on the inside. A special property that could be used to determine its origin," says the anthropologist.

Along with the two geologists Alexander Lukeneder and Mathias Harzhauser from the Natural History Museum in Vienna, who had previously worked with oolites, the team procured comparative samples from Austria and Europe and evaluated them. A complex project: Rock samples from France to eastern Ukraine, from Germany to Sicily were obtained, sawn up and examined under a microscope. The team was supported by the state of Lower Austria, which provided funds for the time-consuming analyses.

The inside also gives information about the outside

The tomographic data from the Venus showed that the sediments were deposited in the rocks in different densities and sizes. In between there were also small remnants of shells and six very dense, larger grains, so-called limonites. The latter explains the previously mysterious hemispherical cavities on the surface of Venus with the same diameter: "The hard limonites probably broke out when the creator of the Venus was carving it," explains Weber. "In the case of the Venus navel, he then apparently made it a virtue out of necessity."

Another finding: The Venus oolite is porous because the cores of the millions of globules (ooides) of which it is comprised had dissolved. This is a great explanation for why the resourceful sculptor chose this material 30,000 years ago: It is much easier to work with. The scientists also identified a tiny shell remnant, just 2.5 millimeters long, and dated it to the Jurassic period. This ruled out all other potential deposits of the rock from the much later Miocene geological era, such as those in the nearby Vienna Basin.

A long way for that period

The research team also analyzed the grain sizes of the other samples. Hundreds, sometimes even thousands of grains were marked and measured with image processing programs or even manually. None of the samples within a 200-kilometer radius of Willendorf even remotely matched. The analysis finally showed that the samples from the Venus were statistically indistinguishable from samples from a location in northern Italy near Lake Garda. This is remarkable because it means that the Venus (or at least its material) started a journey from south of the Alps to the Danube north of the Alps.

"People in the Gravettian—the tool culture of the time—looked for and inhabited favorable locations. When the climate or the prey situation changed, they moved on, preferably along rivers," explains Gerhard Weber. Such a journey could have taken generations.

One of the two possible routes from the south to the north would lead around the Alps and into the Pannonian Plain and was described in simulations by other researchers a few years ago. The other way to get from Lake Garda to the Wachau would be via the Alps. Whether this was possible more than 30,000 years ago is unclear due to the climate deterioration that began at that time. This would be a rather improbable variant if there had already been continuous glaciers at that time. However, the 730 km long path along the Etsch, the Inn and the Danube had always been below 1,000 meters above sea level, with the exception of 35 kilometers at Lake Reschen.

Possible, but less likely, connection to eastern Ukraine

The statistics clearly point to northern Italy as the origin of the Venus oolite. Nevertheless, there is another interesting place for the origin of the rock. It is in eastern Ukraine, more than 1,600 kilometers linear distance from Willendorf. The samples there do not fit as clearly as those from Italy, but better than all the rest of the sample. An interesting connection here: Venus figures were found in nearby southern Russia, which are somewhat younger, but look very similar to the Venus found in Austria. Genetic results also show that people in Central and Eastern Europe were connected to one another at this time.

The exciting story of the Lower Austrian Venus could be continued. Only a few systematic studies have so far dealt with the existence of early humans in this time frame in the Alpine region, and with their mobility. The famous "Ötzi," for example, only comes into play much later, namely 5,300 years ago. "We want to use these Venus results and our new Vienna research network Human Evolution and Archaeological Sciences, in cooperation with anthropology, archaeology and other disciplines, to further clarify early history in the Alpine region," concludes Weber.Venus will soon appear to sink and disappear right before our eyes

Molds and yeasts common in daycares — could cause chronic asthma and allergy

Date:February 23, 2022
Source:American Society for Microbiology

Summary:
Citizen science sampling of dust in outdoor and indoor surfaces led to the identification of building features that contribute to the prevalence of yeasts and molds in daycare centers. This information is important to understand environmental factors contributing to the alarming rise of respiratory chronic diseases in children.


Molds, and especially yeasts, were far more common in indoor daycare centers than outside of them, according to a new study. Factors such as certain building features and the number of children in a daycare influenced the species of fungi found within, suggesting that many of the molds and yeasts probably have indoor sources.

"This information is important to understand the alarming increase in chronic diseases like asthma and allergies in children," said first author Eva Lena Estensmo, Ph.D., University of Oslo, Norway. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

The study was motivated by the rise in chronic allergies and asthma, combined with the general lack of knowledge about the indoor mycobiome, said Dr. Estensmo. "Fungal growth can lead to poor indoor air quality, and some fungi are associated with allergic reactions and respiratory symptoms that may lead to chronic respiratory diseases."

In the study, the researchers investigated the indoor and immediate outdoor mycobiomes of 125 daycare centers in Norway, sampling dust swabbed from the insides and outsides of door frames and correlating the findings with different variables such as the number and ages of children in each daycare, the building type (single building, apartment, etc.), building materials (bricks, wood, etc.), ventilation type, presence of pests, history of mold damage and year of construction.

The study also accounted for environmental data including temperature and moisture levels inside and out, distance from the coast, and longitude and latitude of the daycare centers.

"Especially the high diversity of yeasts came as a surprise," said Dr. Estensmo. "Many might be associated with the human body. We don't fully know whether the yeasts are especially associated with children, but we have some indications -- work in progress -- that far more yeasts are present in daycares than in other indoor environments.

"In addition, the daycare environment with a lot of activity and high density of people is an interesting environment to study in relation to human influence on the indoor mycobiome," said Dr. Estensmo. She said it was well established that the indoor microbiome related to bacteria is influenced by humans, but that much less had been known about human influence on the mycobiome.

"Since young children often bring in organic materials such as soil and litter from nature, daycare centers may accumulate extra organic substrates promoting fungal growth, compared to other indoor environments," the authors wrote. Previously, it has been shown that the concentration of fungi in daycare centers is higher than that in homes.

Citizen scientists played an important role in the research, using materials mailed to them by the investigators to collect dust samples from doorframes both outside and inside the buildings. They also filled out questionnaires the researchers had mailed them, on the number and ages of children in the daycares, the building type (single building, apartment, etc.) and the previously mentioned characteristics of the buildings.

Onset of modern sea level rise began in 1863, study finds

Date: February 24, 2022

Source: Rutgers University

Summary:
Scientists have found that modern rates of sea level rise began emerging in 1863 as the Industrial Age intensified, coinciding with evidence for early ocean warming and glacier melt. The study, which used a global database of sea-level records spanning the last 2,000 years, will help local and regional planners prepare for future sea-level rise

An international team of scientists including Rutgers researchers has found that modern rates of sea level rise began emerging in 1863 as the Industrial Age intensified, coinciding with evidence for early ocean warming and glacier melt.

The study, which used a global database of sea-level records spanning the last 2,000 years, will help local and regional planners prepare for future sea-level rise. The study appears in the journal Nature Communications.

Sea-level rise is an important indicator of broader climate changes. By identifying the time when modern rates of sea-level rise emerged above natural variability, the researchers were able to pinpoint the onset of a significant period of climate change.

By examining the worldwide records, the researchers found that globally, the onset of modern rates of sea-level rise occurred in 1863, in line with the Industrial Revolution. At individual sites in the United States, modern rates emerged earliest in the mid-Atlantic region in the mid to late 19th century, and later in Canada and Europe, emerging by the mid-20th century.

The study is especially timely given NOAA's recently-released report detailing the rapid acceleration of sea-level rise on U.S. coasts.

"We can be virtually certain the global rate of sea-level rise from 1940 to 2000 was faster than all previous 60-year intervals over the last 2,000 years," said Jennifer S. Walker, lead author of the study and postdoctoral associate in the Department of Earth and Planetary Sciences at Rutgers University-New Brunswick. "Having a thorough understanding of site-specific sea-level changes over long timescales is imperative for regional and local planning and response to future sea level rise."

Walker noted that the statistical model the research team utilized could also be applied to more individual sites to further understand the processes driving sea-level change on global and regional scales.

"The fact that modern rates emerge at all of our study sites by the mid-20th century demonstrates the significant influence global sea-level rise has had on our planet in the last century," Walker added. "Further analysis of the spatial variability in the time of emergence at different locations will continue to improve society's understanding of how regional and local processes impact rates of sea-level rise."

More People Are Microdosing for Mental Health. But Does It Work?

Scientists are split over whether the benefits some microdosers experience are a placebo effect or something more.

NEW YORK TIMES

Joseph started microdosing psychedelics five years ago to try to improve his mental health. “I was just kind of in this depression, in this rut,” he said. “I was unhappy and angry and agitated all the time, and it went against the way that I saw myself.”

Depression and anxiety run in Joseph’s family, and he’d been prescribed Prozac as a kid. But when symptoms of depression returned in his early 30s, he didn’t want to go back to a prescription drug.

Joseph, an Austin-based designer (he asked to withhold his full name, citing privacy concerns surrounding mental health issues and illegal drug use), came across research from Johns Hopkins University about psilocybin, the active ingredient in hallucinogenic, or “magic,” mushrooms. In a small study, full doses of the drug helped cancer patients cope with depression and anxiety. Then he read anecdotes of Silicon Valley influencers claiming increased energy from taking tiny doses of psychedelics. So he decided to start microdosing a few times a week, eating a “small nibble” — about half an inch — of mushrooms to see if it would improve his mood.

Almost immediately he started seeing a benefit. “It just kind of boosted my morale,” he said. “I was in a little bit better mood. I had a little bit more pep to my step. I was having a little bit more fun, feeling a little bit more excited about things.”

Microdosing is typically defined by experts as taking 5 percent to 10 percent of a full dose of a psychedelic, usually LSD or psilocybin, as a way to get the supposed mental health benefits of the drug without the hallucinogenic high. For instance, in a clinical setting, a 155-pound man might take 20 milligrams of psilocybin for a full psychedelic experience. For a microdose, he’d take only one to two milligrams. At that level, taken several times a week, some claim the drugs improve their mood, boost their creativity and give the world a brighter, shinier quality, like it’s in high-definition.

“It’s akin to walking outside and the sun is suddenly out,” said Erin Royal, 30, a bartender in Seattle who microdoses one or two times a week with mushrooms she forages from nearby forests. “It reminds you that you are a person who can feel positive things and notice things that are beautiful.”

In practice, only about a third of people who microdose carefully measure the amount of the psychedelic they are taking; most take just enough to begin feeling some effects, which usually start after an hour and last four to six hours. That requires some trial and error — particularly when eating mushrooms, which can vary in psilocybin concentration. (The most commonly reported negative side effect of microdosing is accidentally taking too much, which isn’t dangerous but can be inconvenient if you’re at the office. Researchers also say frequent repeated doses of a psychedelic could theoretically stress the heart.)

Research into the mental health benefits of full doses of psychedelics is promising, and one early-phase study even found that psilocybin, at high doses, may be as effective as a selective serotonin-reuptake inhibitor for treating depression. Full doses of psychedelics help the brain develop new cellular connections, a process called neuroplasticity, and there’s some evidence that microdoses produce similar changes.

So many of the scientists who pioneered research into full doses of psychedelics have started studying whether a microdose might also be beneficial. But evidence is limited, and experts are divided about how microdosing helps people — or if it does at all.

Much of the early research into microdosing has been anecdotal, consisting of enthusiastic survey responses from users who experienced enhanced attention and cognition, feelings of well-being and relief from anxiety and depression. Lab studies of psilocybin and LSD microdoses tend to support these claims, showing improvements in mood, attention and creativity. But these studies have generally been small, and they didn’t compare a microdose to a placebo.

“You probably only participate at this point in a trial in microdosing if you really have a strong belief that this might help you,” said Dr. David Erritzoe, clinical director of the Centre for Psychedelic Research at Imperial College London. And when people expect to benefit from a drug, they typically do.

The two largest placebo-controlled trials of microdosing were published last year, and they both suggest that the benefits people experience are from the placebo effect. In the studies, volunteers used their own drugs to participate and, unknown to them, received either active doses or a placebo packaged in identical capsules. At the end of several weeks, almost everyone’s mood and well-being had improved, regardless of what they had taken.

“I was initially surprised but also a bit disappointed by the results, because when we set up the study we were quite optimistic that microdosing could have an effect” beyond a placebo, said Michiel van Elk, an assistant professor of cognitive psychology at Leiden University in the Netherlands who led one of the trials.

Dr. Erritzoe, who ran the other study, found that the drug’s efficacy was tied to users’ expectations. If they took a placebo but thought it was a microdose, they felt better, and if they had an active dose but wrongly guessed it was a placebo, they did not.

A third placebo-controlled trial, published earlier this month from the University of Chicago, tried to get around user expectations by giving participants four microdoses of LSD over the course of two weeks, but without telling them about the purpose of the study or even what they were taking. Once again, there was no difference between the LSD and placebo groups.

Still, some scientists point to evidence showing that microdosing has a direct impact on the brain to argue that its benefits are real. Using neuroimaging technology, researchers have shown changes in brain activity and connectivity after single small doses of LSD that are similar to what’s seen with larger amounts of the drug. And a study in Denmark found that a microdose of psilocybin activated nearly half of the specific type of serotonin receptors that psychedelics act on to produce their hallucinogenic effects.

“I wouldn’t say it’s all placebo. Clearly, it’s an active drug,” said Harriet de Wit, a professor of psychiatry and behavioral neuroscience at the University of Chicago who led several of the studies. “We see brain changes that are a little bit like the high dose effect,” which suggests the smaller doses are acting on the same systems.

Some microdosing researchers, like Dr. de Wit and Dr. van Elk, remain optimistic that tiny amounts of hallucinogenic drugs will ultimately prove beneficial for mental health and cognition. They say that the design of the placebo-controlled trials may be to blame for their lack of significant findings. The studies may not have run for long enough, or the tests and questionnaires used during the studies may not fully capture the benefits some people experience from microdosing.

On the other side, Dr. Erritzoe said that just because a drug has an impact on the brain doesn’t mean it has any therapeutic value. “If you can’t see in a proper trial that it works for the symptoms, for things that people can actually detect and feel and experience in their lives, then it’s just not that interesting,” he said.

“I’m not trying to shoot down microdosing,” he added. “I’m just being cautious and saying at the moment, it does not look particularly optimistic.”

One of the biggest problems with microdosing research is that it’s hard to block the placebo effect in studies of a psychoactive substance. In Dr. Erritzoe’s trial, 72 percent of people correctly guessed what they had taken, which means it’s no longer blinded. For the studies showing effects in the brain, the biggest changes came at the higher end of the microdosing spectrum — 20 to 26 micrograms of LSD and 3 milligrams of psilocybin — an amount where people often start noticing the drug’s effects.

Out of the lab, most users dose themselves aiming for a similar subtle awareness that they’ve taken something. At that level, the microdose might be closer to a half dose, or their expectations could heighten the drug’s benefits because they can feel that it’s doing something.

As a result of these difficulties and the lack of conclusive findings, Dr. van Elk has abandoned microdosing research to go back to studying large doses of the drugs. Dr. Erritzoe said once his next study ends, he’ll probably do the same.


Both Joseph and Ms. Royal are aware that the benefits of microdosing could be a placebo effect. But for them, how it works matters less than the fact that it’s helped. These days, Joseph said his depression has improved thanks to a regular meditation practice, although he still microdoses occasionally if he starts feeling down.

After several years of microdosing, he said the biggest change he’s experienced is a general shift in his mind set — something that’s harder for scientists to measure. “I started because I read that it helps with depression,” he said. “But as I’ve moved on, it’s helped really a lot more with mental and personal growth and outlook on life — how you want to live and your existence in the world.”

MERRICKVILLE, Ontario — There aren’t many scientists raised in the ways of druids by Celtic medicine women, but there is at least one. She lives in the woods of Canada, in a forest she helped grow. From there, wielding just a pencil, she has been working to save some of the oldest life-forms on Earth by bewitching its humans.

At a hale 77, Diana Beresford-Kroeger is a medical biochemist, botanist, organic chemist, poet, author and developer of artificial blood. But her main focus for decades now has been to telegraph to the world, in prose that is scientifically exacting yet startlingly affecting, the wondrous capabilities of trees.

Dr. Beresford-Kroeger’s goal is to combat the climate crisis by fighting for what’s left of the great forests (she says the vast boreal wilderness that stretches across the Northern Hemisphere is as vital as the Amazon) and rebuilding what’s already come down. Trees store carbon dioxide and oxygenate the air, making them “the best and only thing we have right now to fight climate change and do it fast,” she said.

Her admirers, who included the late biodiversity pioneer E.O. Wilson, say what sets Dr. Beresford-Kreoger apart is the breadth of her knowledge. She can talk about the medicinal value of trees in one breath and their connection to human souls in the next. She moved Jane Fonda to tears. She inspired Richard Powers to base a central character of his Pulitzer-prize winning novel, “The Overstory,” in part on her: He has called her a “maverick” and her work “the best kind of animism.”

Dr. Beresford-Kroeger has also cultivated an arboreal Noah’s Ark of rare and hardy specimens that can best withstand a warming planet. The native trees she planted on her property in this rural village sequester more carbon and better resist drought, storms and temperature swings, she said, and also produce high quality, protein-rich nuts. If industrial logging continues to eat away at forests worldwide, soil fertility will plummet, and Dr. Beresford-Kroeger, an Irishwoman, is haunted by the prospect of famine.

She is an independent researcher, unaffiliated with any institution, funded by her writings and the sale of her rare plants; she wanted freedom to study and spread her ideas without any strictures.

“Often these kinds of brilliant pioneers are outliers who don’t play by the rules,” said Ben Rawlence, an English writer who found himself “sitting at her feet doing a master’s in the boreal forest packed into three days” while researching his new book “The Treeline: The Last Forest and the Future of Life on Earth”.

“People like her are very important,” he said. “They can integrate the depth of different disciplines into a total picture.”

Dr. Beresford-Kroeger didn’t set out to be an outlier. Born in England and raised in Ireland, she studied botany and biochemistry at the University College Cork before coming to America in 1966 to research organic and radionuclear chemistry at the University of Connecticut. Three years later, she moved to Canada to study plant metabolism at Carleton University, and then do cardiovascular research at the University of Ottawa, where she began working as a research scientist in 1972.

But she faced sexism, harassment and, in that part of Loyalist Canada, anti-Irish sentiment, she said. She left academia in 1982, as much repelled by the toxicity as she was drawn to a deeper calling, rooted in a childhood that was both Dickensian and folkloric.

Dr. Beresford-Kroeger was orphaned at 12. Her father, an English aristocrat, died under mysterious circumstances, while her mother, who traced her lineage to ancient Irish kings, perished in a car crash. Dr. Beresford-Kroeger was taken in by a kindly if neglectful uncle in Cork, and spent her summers with Gaelic-speaking relatives in the countryside.

There, under the tutelage of a maternal grandaunt, she was taught ancient Irish ways of life known as the Brehon laws. She learned that in Druidic thinking, trees were viewed as sentient beings that connected the Earth to the heavens. She was also versed in the medicinal properties of local flora: Wildflowers that warded off nervousness and mental ailments, jelly from boiled seaweed that could treat tuberculosis, dew from shamrocks that Celtic women used for anti-aging.

As a university student a few years later, Dr. Beresford-Kroeger put those teachings to the scientific test and discovered with a start that they were true. The wildflowers were St. John’s Wort, which indeed had antidepressant capacities. The seaweed jelly had strong antibiotic properties. Shamrocks contained flavonoids that increased blood flow. This foundation of ancient Celtic teachings, classical botany and medical biochemistry set the course for Dr. Beresford-Kreoger’s life. The more she studied, the more she discovered that the symbiosis between plants and humans extended far beyond the life-giving oxygen they produced.

“Every unseen or unlikely connection between the natural world and human survival has assured me that we have very little grasp of all that we depend on for our lives,” she wrote in her most recent book, “To Speak for the Trees.” “When we cut down a forest, we only understand a small portion of what we’re choosing to destroy.”

Deforestation, she continued, was a suicidal, even homicidal, act.


“We’ve taken down too much forest, that’s our big mistake,” Dr. Beresford-Kroeger said during a recent chat in her hand-built home, as her husband, Christian Kroeger, puttered in the kitchen, making lunch. “But if you build back the forests, you oxygenate the atmosphere more, and it buys us time.”

The Beresford-Kroegers live south of Ottawa, down a long country lane on a 160-acre parcel of land they bought decades ago. Their house is filled with well-thumbed books, fingers of sunlight, thriving plants and Boots, their rescue cat. Dr. Beresford-Kroeger writes all of her papers and books by hand, and doesn’t have a smartphone or computer or any social media accounts. When she needs to Zoom, she pops down to the local library and uses a public desktop.

Outside the house, her treasured trees grow, all climate-change resistant to varying degrees: the kingnut, a blue-needled fir and a rare variant of the bur oak. She began creating her arboretum after learning that many key tree species prized by First Nations people for medicines, salves, oils and food had been razed by colonizers centuries ago.

“These trees have fed the continent before in the past,” she said. “I want them available there for people in the future.”
Over the years, she painstakingly tracked down, across the continent and beyond, rare seeds and saplings native to Canada. “I thought, ‘Well I’m going to repatriate these trees,’” Dr. Beresford-Kroeger said. “I am going to bring them back to here, where I know they’re safe.”

She also knew if the “repatriated” plants and trees were shared far and wide, they’d no longer be lost. She and Christian began giving away native seeds and saplings to pretty much anyone who asked. Among the tens of thousands of recipients were local Hell’s Angels, who roared up to their doorstep to collect black walnut seedlings, wanting to grow the valuable trees on their property nearby. “I put them in the back of their motorbikes, their Harley-Davidsons, she said. “I thought I’d die of a heart attack. But they were very nice to me.”

In her forties, Dr. Beresford-Kroeger turned to writing, though it would take a decade to find a publisher for her first manuscript. She has since published eight books, at least a couple of them Canadian best sellers. One was about holistic gardening, another about living a pared-down life. But her main focus was the importance of trees.

She wrote about the irreplaceability of the boreal forest, which principally spans eight countries, and “oxygenates the atmosphere under the toughest conditions imaginable for any plant.” She introduced her “bioplan”: If everyone on earth planted six native trees over six years, she says it could help to mitigate climate change. She wrote about how a trip to the forest can bolster immune systems, ward off viral infections and disease, even cancer, and drive down blood pressure.

There have been skeptics. One publisher admonished her for being a scientist who described landscapes as sacred, she said. The head of a foundation, while introducing her following a screening of “Call of the Forest,” a documentary about her life, let slip that he didn’t believe a word of what she said.

Bill Libby, an emeritus professor of forest genetics at the University of California, Berkeley, said he initially had reservations when Dr. Beresford-Kroeger offered a biological explanation for why he felt so good after walking through redwood groves. She attributed his sense of well-being to fine particles, or aerosols, given off by the trees.

“She said the aerosoles go up my nose and that’s what makes me feel good,” Dr. Libby said.

Outside research has supported some of those claims. Studies led by Dr. Qi Ling, a physician who coedited a book for which Dr. Beresford-Kroeger was a contributor, found visits to forests, or forest bathing, lessened stress and activated cancer-fighting cells. A 2021 study from Italy suggested that lower rates of Covid-19 deaths in forested areas of the country were linked in part to immunity-boosting aerosols from the region’s trees and plants.

“I was laughed at until fairly recently,” Dr. Beresford-Kroeger said, her Irish accent still strong. “People all of a sudden seem to be waking up.”

Nowadays, Dr. Beresford-Kroeger is in great demand, a shift she attributes to mounting fears about the environment and a hunger for solutions.

In 2019, Carleton University awarded her a doctorate in biology along with an honorary doctor of law degree for her climate work. The next year, she was a guest on one of Jane Fonda’s televised climate action teach-ins. She regularly delivers virtual talks to universities and keynote addresses to organizations (“I had goose bumps talking to her,” said Susan Leopold, the moderator of her talk at the 2021 International Herb Symposium). She is helping to plan medicinal healing gardens in Toronto and outside Ottawa as she finishes a new book about how people are spiritually connected to nature. “The publishers can like it or bloody lump it,” she said.

During a tour of her forest and gardens, Dr. Beresford-Kroeger spoke with wonder about how ancient Celtic cures were almost identical to those of Indigenous peoples, and waxed poetic about the energy transfer from photons of sunlight to plants’ electrons during photosynthesis.

Then she advised a reporter to lean against a tree before writing. People, she said, should look at forests as “the sacred center of being.”

“Without trees, we could not survive,” she said. “The trees laid the path for the human soul.”

How union drives in Mexico help workers on both sides of the border

These are vital, promising steps under the USMCA, which requires Mexico to enforce the labor rights needed to lift up workers there and, in turn, level the playing field for workers north of the border.

What Tom O’Shei remembers most about his visit to Mexico in 2019 is the determination he glimpsed in the hundreds of Mexican workers who paraded through the port city of Lázaro Cárdenas and stopped to pray at a monument honoring a pair of murdered union activists.

Although the marchers gathered to remember the past, O’Shei knew their thoughts were also fixed on a future day when they’d win their fight for labor rights and help build a fairer economy across North America.

That day is edging closer under the 19-month-old United States-Mexico-Canada Agreement (USMCA), which American labor leaders and their allies pushed over the finish line with provisions aimed at ending the exploitation of workers in all three countries.

Thousands of workers at a General Motors plant in Silao, a few hundred miles north of Lázaro Cárdenas, voted by a landslide on February 3 to join a real union and fight for decent pay and working conditions. And long-mistreated workers at auto parts manufacturer Tridonex, just across the border from Brownsville, Texas, are scheduled to vote on February 28 on choosing their own union.

These are vital, promising steps under the USMCA, which requires Mexico to enforce the labor rights needed to lift up workers there and, in turn, level the playing field for workers north of the border.

“I’m sure it’s going to help with other facilities going forward,” explained O’Shei, president of United Steelworkers (USW) Local 135L, who looks for workers at other Mexican plants to emulate the union drives at GM and Tridonex. “They’re no different than us. They want to be able to feed their families.”

“When they do well, we do well, because our work is less likely to be outsourced to a country paying its workers a decent wage,” added O’Shei, who represents hundreds of USW members at the Sumitomo plant in Tonawanda, New York, and twice joined USW delegations that traveled to Mexico to stand in solidarity with union supporters there.

Under the USMCA’s failed predecessor, the North American Free Trade Agreement (NAFTA), employers shifted a million manufacturing jobs to Mexico to take advantage of the low wages as well as the lack of labor rights, weak safety standards and lax environmental regulation.

This race to the bottom decimated northern manufacturing communities while holding Mexican workers in poverty. Workers at the GM plant in Silao, for example, make only a few dollars an hour.

The February 2006 explosion at the Pasta de Conchos mine, which killed 65 people, underscored the safety lapses Mexican workers faced under NAFTA, as did the police killings of the two union supporters in Lázaro Cárdenas during a strike that followed the mining tragedy.

Mexican workers who tried to organize during the NAFTA era did so at the risk of their lives, and the government forced Napoleón Gómez Urrutia, the president and general secretary of Los Mineros, one of the country’s few real labor unions, into exile in Canada for more than 12 years.

“We don’t have to take a beating or see people we know die because they were fighting for representation,” observed O’Shei, marveling at the perseverance of union activists in Mexico.

The USMCA requires Mexico to give workers the right to form independent unions, elect their own leaders and vote on real contracts. The changes empower workers—like those at GM and Tridonex—to oust corrupt protection unions that conspired with employers to suppress wages and silence dissent.

And the USMCA includes first-of-its-kind enforcement mechanisms to prevent Mexican employers and anti-union thugs from thwarting organizing drives or otherwise violating new labor rights.

Last year, for example, the fake union at the GM plant in Silao tampered with ballots during a contract vote to hold on to power. The U.S. government filed a complaint under the USMCA, and Mexican authorities ordered a revote.

Workers then rejected the rigged contract by a huge margin. That set the stage for the workers’ vote on February 3 to bring in true representation—the National Independent Union for Workers in the Automotive Industry, or SINTTIA.

The AFL-CIO and Mexican labor activists, among other groups, filed their own complaint last year after Tridonex harassed and fired hundreds of workers attempting to organize.

The company settled the allegations by agreeing to provide hundreds of thousands of dollars in back pay and setting up a hotline for workers to report labor violations, among other penalties. Finally, on February 28, workers fed up with years of abuse will have the chance to elect a legitimate union and take control of their futures.

To sustain the kind of cross-border solidarity pivotal in these cases, the USW regularly sends delegations to Lázaro Cárdenas.

In 2019, O’Shei and the other USW representatives marched through the city shoulder to shoulder with Mexican workers, including members of Los Mineros. The American and Mexican workers exchanged T-shirts in an expression of solidarity.

And the USW delegation attended a Los Mineros union meeting and other events, where O’Shei met Juan Linares, a union leader, who spent years in prison for refusing to inform on fellow union supporters.

“That’s not something a lot of people would do,” O’Shei said. “He’s probably one of the most impressive people I’ve ever met. It’s invigorating to be around people who are so close to their struggle to organize, to see the enthusiasm and love they have for their union.”

When billionaires don’t pay taxes, people ‘lose faith in democracy’

The rich can live lavishly by employing a technique known as “Buy, Borrow, Die,” in which they buy or build assets, borrow against them and then avoid estate and gift taxes when they die.

SOURCEProPublica

Last year, ProPublica began publishing “The Secret IRS Files,” a series that has used a vast trove of never-before-seen tax information on the wealthiest Americans to examine their tax avoidance maneuvers.

Since then, the Biden Administration and Democrats in Congress have been trying to close loopholes in the code and raise taxes on the rich to fund their legislative priorities. But the efforts have stalled, amid claims by Republicans that tax increases on billionaires would “destroy investment in America and punish success in America” and resistance from key Democrats, Sen. Joe Manchin, who called such a plan divisive, and Sen. Kyrsten Sinemawho has opposed tax increases more broadly.

Ron Wyden, the Oregon Democrat who chairs the Senate Finance Committee, is one of the top experts in Congress on tax matters and an advocate of raising taxes on the rich. He has proposed a bill that would build on his past efforts to tax the wealthiest. The most recent legislation would tax people with $1 billion in assets (or $100 million in income for three years in a row) not just on their income as it is traditionally defined but also on the growth of their wealth each year. It would take a bite out of so-called unrealized gains, taxing a rise in the value of the stocks, bonds and other assets owned by the ultrawealthy — even if they didn’t sell the assets. For assets that are not readily traded, Wyden’s bill would impose a deferred tax, an annual interest charge that would be added to any capital gains tax owed when the wealthy person sells the asset.

Wyden’s bill seeks to counteract a technique that the ultrawealthy can use to avoid income taxes: They hold on to their assets and simply avoid the income — and tax — that comes when they sell them. The rich can live lavishly by employing a technique known as “Buy, Borrow, Die,” in which they buy or build assets, borrow against them and then avoid estate and gift taxes when they die.

We checked in with the senator to ask about his proposal and the prospects for any new laws in the coming year.

The interview that follows has been edited and condensed for clarity.

As you know, we’ve been reporting on how little tax the ultrawealthy in America pay. Our reporting for the first time has put names and faces and specifics on this issue by pointing out that Jeff Bezos and Elon Musk and the like have paid zero in taxes in recent years. And that the ultrawealthy really pay a low rate when compared to their wealth growth. I’m wondering if seeing these numbers has had an effect on your thinking, and if you think there’s been an effect on colleagues of yours who may not have had this full appreciation the way you did?

The answer is really yes and yes. It has affected me, and it’s affected, I believe, other senators. And the fact is my bill raises $557 billion, and it does so by simply requiring billionaires to pay taxes every year, the way nurses and firefighters do. At the same time, I feel very strongly — and this is the point where I think we’ve made real headway — this is about more than revenue. This is about fixing a thoroughly broken tax code and showing working people in America that billionaires don’t get to play by a different set of rules. My view is the big scandal is what’s legal. When you walk these people through it, it causes people to lose faith in government, lose faith in democracy.

What really causes people to lose faith? I think the fact that billionaires occasionally pay zero in taxes will strike most people as wrong. But are there other things that strike you as really jeopardizing their faith in the system?

The fact is it’s so brazen. Some of the leading conservative publications write articles: “Buy, Borrow, and Die if you want to pay little or nothing. Here is the plan.” I tell people about this at my town hall meetings and everybody starts hollering: “Don’t let people back here get played as suckers by letting billionaires pay little or nothing for years on end while those of us who represent a vast majority of Americans get hammered.”

We’ve been struck that some of the most loyal and closest readers of our stories have been the wealth advisory industry, figuring out a how-to manual. This is not what we intended …

You have a proposal, which you alluded to, that would raise in your estimate almost $600 billion over 10 years. What are the prospects for that? Because you re-upped a version of that last year and it was quickly shot down by Joe Manchin, as I understand.

A couple of things, first of all, Joe Manchin has always said that he believes that the wealthiest should pay their fair share. And that’s very much in sync with what we say. And I go on to say that paying your fair share and being successful are not incompatible. That’s one of the things that special interests that have opposed my proposal say: “Oh, this is going to keep people from being successful.” Are you kidding me?

We know that there are lots of lobbyists and PR firms working around the clock to protect the status quo. There are terrific organizations like Patriotic Millionaires and Americans For Tax Fairness, but they just don’t have the same resources that the billionaires have. That’s why we’re trying to get the message out and lay out that this is basically a fairness issue. This is fundamentally about fairness so the affluent pay their fair share and it is not going to unravel the American dream of being successful.

The other part about this is the double standard. We had another hearing last week, and some of the conservative Republicans were talking about Earned Income Tax Credit recipients being the problem with tax evasion and noncompliance. The reality is you can be a tax cheater, a wealthy tax cheater. You can have one of these very large passthroughs and you are more likely to get hit by a meteor than you are to get audited.

In another part of our series, we focused on the ways that fortunes can persist from generation to generation. We wrote a story about the Scrippses and Mellons and their heirs getting vast amounts of income from fortunes that were created over 100 years ago. We also wrote about how many of the current 100 wealthiest people in the country are using GRATs [Grantor Retained Annuity Trusts] and other trusts to avoid paying income taxes. Is that on the agenda in DC? I know there was a proposal out of the House with the original version of Build Back Better, but is fixing that on the agenda, still?

I’m glad you asked that question. We get around that and stepped-up basis [the provision that, at the time of a person’s death, wipes out any increases in the value of their holdings for tax purposes, allowing people to pass on assets without paying capital gains tax] and all these things [with my proposal], because the billionaires could pay taxes each year and their heirs no longer get to wipe out billions and billions of dollars worth of gain. And I support proposals to fix GRATs. We’ve worked on them, and the bottom line is the overarching change, which is that billionaires are going to pay taxes every year.

So you’re saying under that proposal all these other fixes like stepped-up basis wouldn’t be as important. But is something like ending stepped-up basis, which was floated earlier this year, still on the table?

I’ll give you an example. I worked for a long time on the idea of making it crystal clear that farms and family-owned small businesses were fully exempt from [my proposal to end] stepped-up basis. But the ultrawealthy just kept saying, “Oh, the sky’s going to fall” once we allow this. Everybody is going to get hit with their farm and their small business and the like, and basically what they do is they play to people’s fears and try to create enough lobbying pressure. The billionaires try to get these small guys out in front to do their bidding for them.

And one quick thing. This is about a billionaires income tax. It’s a very important differentiation. This is about paying every year. They’ve got a stock account, for example, and this year it’s $20 billion and next year it goes up to $23 billion. They pay the capital gains tax on three billion bucks, because we feel that they’re basically evading capital gains taxes. And this is the way we respond with a billionaires income tax. And we chose that word very specifically.

Right. It’s a definition of income. It’s a definition that some economists have embraced. It’s not the orthodox definition. It’s not the definition that is in the current tax system, of course.

It’s particularly important when people say, “Oh, well, what are we going to do if it goes down?” Well, our proposal would account for losses as well.

But the fact is that extra $3 billion that they have this year that they didn’t have last year, they can use for all kinds of things. They can borrow against it. They can have a wonderful lifestyle, they can do all kinds of things. It’s very real to them in terms of how they can use it. And it’s immediate.

Now, I was interested in the counterarguments because one of those is that if they take a loss, how does that get accounted for in the system? The other is that you don’t want to force people into having to sell to raise cash to pay the tax. Another argument is that this will push people into illiquid, hard-to-value assets and out of the public markets. And I’m curious how you address all these objections.

We technically make that unlikely because the hard assets, they pick up interest charges as time goes along.

Washington seems to be very focused on marginal rates, on income tax with the traditional definition of income. I wonder what you think of that, if that’s kind of frustrating to you?

There can be that argument for raising those marginal rates, particularly on, again, wealthy people. But here’s an example of the kind of bizarre reality you get. I went to school on a basketball scholarship, dreaming of playing in the NBA — pretty ridiculous idea because I’m 6-foot-4 and made up for it by being kind of slow. I still kind of follow basketball. And as we heard about the fact that some members wanted to raise marginal rates and weren’t going to do anything on billionaires, it became clear to me that you could have a young basketball player, first one to go to college, get a scholarship. They come out, get a big contract. It’s all income. They’re going to come out under the marginal rate. Meanwhile, the owner of the club who is a billionaire doesn’t pay, themselves. an income tax, gets off scot-free. How is that fair?

That is the other point that you guys are raising.

What could be the basis of some kind of compromise that could shift this dynamic, because it sort of stalled last year?

We have looked at virtually every other approach to ensure a sense of fairness, that billionaires would pay taxes every year, like nurses and firefighters. And a number of the people who are most knowledgeable on the other side have actually committed candor when they said, [your bill] will actually require that we pay something every year, and everything else that’s been put out there can basically be gamed. People in the industry who are the advocates for the billionaires said that it’s going to be hard to avoid.

I’m not sure anything is going to get a perfect solution, but this is the one they’re really worried about because I can explain it pretty straightforwardly. If you make $3 billion between ’22 and ’23, you pay a capital gain rate at 23.8%.

One other point: We had folks say that they were concerned about founders of companies, and so we’ve made some adjustments to allow founders of companies to designate some stock as nontradable.

We’re always listening to members and trying to respond to their concerns.

People would say, “Well, what about philanthropy?” Well, philanthropy is terrific. We encourage it, but you have Medicare and Social Security and these critical needs that need to get addressed. Because if we’re all in this together, philanthropy is not going to take care of Medicare and Social Security.

These proposals, and your proposal in particular, are being blocked by members of your own party. Do you have any understanding of what Joe Manchin would support or what Kyrsten Sinema would support?

I’m not going to speak to the concerns of any one member, but let’s put it this way: No member is saying that they are publicly opposed to the idea of billionaires paying their fair share.

I’m not underestimating the power of the billionaires. You got to get everybody on board, got to hit 50 votes. And that’s what we’re focused on. But nobody has publicly said that billionaires shouldn’t pay their fair share. And the reason why is because this idea has enormous potency with people.

Do you think that anything can be done before the midterm elections?

We’re doing everything we can to come back as soon as possible from what happened in December. It kind of went off the rails. The next round of discussion will be built on health care, particularly holding down the cost of prescription drugs and filling in gaps in the Affordable Care Act like Medicaid coverage, our Clean Energy for America bill, which says for the first time the more you reduce carbon emissions, the bigger your tax savings, and then revenues evaded by tax avoidance and closing loopholes.

Gotcha. And another big problem here is that the IRS is in profound straits with the budget problems and tens of thousands of employees having left. How dire a situation is that, and where is the consensus to fund the IRS adequately?

So, first of all, as the chairman of the finance committee, I have led the effort, the pushback against Republican cuts in the IRS budget for years. Republicans in their big 2017 tax bill didn’t do anything to deal with the IRS budget cuts.

Now, I also want to take this opportunity because people have asked about the ability to administer our bill. There isn’t any issue with the IRS valuation because the value of stocks and the like is easily known and nontradable assets are only taxed when sold, just like today, so that “oh my God, Western civilization is going to end,” the IRS can’t administer it, I think is just contradicted by the facts which I just gave you. And, by the way, when billionaires said it’ll be difficult to comply, they got armies of accountants and lawyers to help them avoid taxes, paying as little as possible. They can just use their accountants and lawyers to comply and pay what they owe.

I’ll just for my closure say that, when you really look at the challenges for democracy, tax fairness is one of the keys and that’s what this is all about. Yes, it’s about raising over $550 billion — no question, it’s the biggest revenue raiser in the package — [but] this is about core issues of fairness.
