High-protein diets may decrease testosterone levels in men, leading to ED, fertility struggles

WORCESTER, England — Gym buffs who knock back protein shakes and devour lean meats are lowering their chances of having kids, warns a new study. Following a high-protein diet may reduce men’s testosterone levels, which can lead to erectile dysfunction and low sperm counts, say scientists.

Men who are looking to build muscle or lose weight are often encouraged to consume large amounts of lean meats, fish and protein shakes. But now scientists at the University of Worcester say pilling on the protein could cost them dearly, decreasing their testosterone levels by more than a third.

Cutting out carbs, which has become increasingly popular with celebs like Kim Kardashian, also comes at a price, the researchers report.

“Most people eat about 17 percent protein, and the high protein diets which caused low testosterone were all above 35 percent, which is very high,” says lead researcher Joseph Whittaker, a doctoral student at the university, in a statement per South West News Service. “So for the average person, there is nothing to worry about, however for people on high protein diets, they should limit protein to no more than 25 percent.”

Not having enough testosterone has also been linked to chronic diseases like heart diseasediabetes and Alzheimer’s. In contrast, healthy testosterone levels are very important for strength, muscle building, and athletic performance.

Results from 27 studies involving a total of 309 men were compiled by the researchers. Those who followed a high protein, low carb diet had much lower levels of testosterone compared to others. Having more than 35 percent protein reduced testosterone levels by 37 percent, which is medically referred to as hypogonadism, the researchers found.

Too much protein and not enough carbs also increased cortisol, commonly known as the body’s stress hormone, which is released during the “so-called fight or flight” response. High levels of cortisol have been found to suppress the immune system, leaving people vulnerable to viral and bacterial infections like colds, flus and COVID-19.

Packing on the protein can also cause “rabbit starvation,” where the body turns too much protein into ammonia which is toxic at high levels. This condition, sometimes called “protein poisoning,” was first discovered by Roman soldiers who were forced to survive on rabbits during the siege of Villanueva del Campo. Many of them developed severe diarrhea and died.

“The finding that low carbohydrates diets increase cortisol is very interesting, as these diets have become incredibly popular over recent years, with many celebrities such as Kim Kardashian, LeBron James, and Meagan Fox, promoting them,” Whittaker says. “However further work needs to be done in this area, to know if this is necessarily bad.”

The findings are published in the journal Nutrition and Health.

The late 1940s encompassed a unique period for women in science in the United States. After scores of women had entered scientific, technological, engineering, and mathematical fields for the first time to support the war effort, American women were routinely discouraged from pursuing STEM careers in the postwar era. Many top colleges and universities refused to admit women as students until the late 1960s or early 1970s. Women of color were particularly hard to find in labs and in scientific journals during the mid-twentieth century.

This was the climate in which Mildred "Millie" Dresselhaus found herself when she first enrolled as an undergraduate at Hunter College in New York City in 1948. Dresselhaus would eventually become a decorated MIT physicist, making highly influential discoveries about the properties of materials. Based on her far-reaching foundational research, scientists and engineers have made enormous advances at the nanoscale—discovering structures like spherical carbon "buckyballs," cylindrical carbon nanotubes, and 2D carbon sheets known as graphene that have made products from aircraft to cellphones stronger, lighter, and more efficient. But her rise to science stardom from humble beginnings was improbable, and Dresselhaus began her college experience with low expectations.

As a child, Dresselhaus had her fill of science inspirations, including issues of National Geographic she bought with pocket change, as well as books such as "Microbe Hunters," a dramatic account of medical victories by Paul de Kruif, and "Madame Curie," a biography of two-time Nobel laureate Marie Curie by her daughter, Eve Curie. There were also clandestine visits to the Hayden Planetarium, into which Dresselhaus would regularly sneak on account of being unable to pay admission.

Yet academic research was not something she could envision for long-term pursuits. Although she had earned high marks at a top magnet school for girls, she was told that only three career paths were open to her: teaching, secretarial work, and nursing. In fact, Dresselhaus' top priority entering college was to improve on the financial situation that her parents, poor immigrants from Eastern Europe, had struggled through during the Great Depression—a condition so dire that they sometimes had difficulty putting food on the table. In high school, Dresselhaus made great strides toward her goal by developing a lucrative tutoring business. And so, when she first enrolled at Hunter College, she planned to become a teacher. But what actually happened was a little more extraordinary.

With advanced standing due to strong high school grades, Dresselhaus thrilled to take on a healthy serving of electives, mostly in math and science, in her first year at Hunter. But things changed quickly for her as a sophomore. It was at this time that she met and instantly bonded with someone who would serve as a teacher, a role model, a friend, and even something of a mother figure during their many decades in contact.

An eminent exemplar

Rosalyn Sussman Yalow is best known as the second woman to win the Nobel Prize in Physiology or Medicine, a feat she accomplished in 1977 for her development of the radioimmunoassay technique, a way to use radioactive labeling to measure concentrations of biological and pharmacological substances in blood. (Yalow shared the Nobel with two others for unrelated work; her longtime collaborator, Solomon Berson, had died and was therefore ineligible for the prize.) The first woman to win the medicine prize, Gerty Cori, had done so exactly three decades earlier, when she shared the 1947 Nobel with her colleague (and husband) Carl Cori and with Argentine researcher Bernardo Houssay for their collective work on sugar metabolism.

For Yalow, the first American-born woman to win any Nobel in science, her path to success was like an ant's course to its nest—meandering but with a singular objective: translating her scientific acumen into a career focused on research. When Yalow met her future protégé, just two years after Cori received her Nobel in Stockholm, she was struggling to find a place for herself within the scientific community.

Yalow in fact had attended Hunter College a decade prior and in the process became the institution's first physics graduate. In an effort to pry open a door to a research career, she worked briefly as a secretary before following an opportunity to teach—and earn a PhD in nuclear physics—at the University of Illinois. But research positions remained largely closed to women—and Jews—during the mid-1940s, especially after World War II veterans returned from service. She eventually landed a full-time research position at what was then the Bronx Veterans Administration Hospital, where she would remain for the next four decades until her retirement. But prior to finding that research home, Yalow returned to her alma mater as a way to tread water while she figured out her next move. She served as an adjunct professor at Hunter for only a few years, but her timing was incredibly consequential for the trajectory of one student in particular. Were it not for Yalow and her star pupil overlapping for approximately sixteen months at a city college in the country's largest metropolis, the course of Dresselhaus' history would have been drastically different.

In February 1949, Dresselhaus enrolled in an introductory-level physics course that covered the basics in Yalow's specialty, nuclear physics. The class, she said, "totally knocked me over," and with enrollment in the single digits, student and teacher got to know each other well. They bonded immediately, in what Dresselhaus later described as "sort of love at first sight." While Dresselhaus found in Yalow a scientist who shared her passion for inquiry and provided strong academic and career encouragement, Yalow saw a bit of herself in the whip-smart Dresselhaus, who shared a drive to follow her academic interests, regardless of whatever rules—actual or understood—she had to bend in order to do so.

Yalow became a trusted mentor who would nurture Dresselhaus in ways large and small throughout her career. The strongest means of early support was encouraging her to forget teaching and pursue research. "She was the one who was most influential in leading me to attend graduate school and to go to the best schools and to study with the best scholars," Dresselhaus said of Yalow. "She [told] me that I could make it even though I was a woman, and she did warn me that the road ahead for women in science might be more difficult, but not to be deterred."

To supplement her course work, Yalow suggested that Dresselhaus attend colloquia hosted by the Columbia University Department of Physics, home to individuals like Willis Lamb and Polykarp Kusch, who would go on to share a Nobel Prize for work on electrons and hydrogen, and to Chien-Shiung Wu, an expert in radioactive decay whose monumental experiment on the conservation of parity would lead to a Nobel for two of her male colleagues. Yalow also invited Dresselhaus to her home on at least one occasion. "That was amazing; no other teacher ever did that," Dresselhaus said.

In truth, encourage may not be the most accurate word to describe Yalow's early support. According to Dresselhaus, once her mentor recognized her talent, she all but insisted that Dresselhaus change her plans for the future. "Rosalyn was quite a domineering person," she recalled after winning the prestigious Kavli Prize in 2012. "She just gave orders, and I pretty much did what she said." In a New York Times interview that same year, Dresselhaus said of Yalow, "You met her and she said, 'You're going to do this.' She told me I should focus on science. She left the exact science unspecified but said I should do something at the forefront of some area."

The two had different personalities. Dresselhaus was generally accommodating, quick to avoid confrontation, and always seeking places where she could quietly make a positive mark, whereas Yalow was singularly headstrong. This could be a positive attribute for someone striving for leadership, especially at a time when women were still seen as inferior to men in science (and many other realms). "She has to be that way," Dresselhaus explained to Yalow biographer Eugene Straus. "If she weren't that way she wouldn't be what she is today. That very strong focus. The world is gray, but she is able to make black and white out of it, and that's always helped her."

Yet when she took someone under her wing, as she did with Dresselhaus, Yalow was extremely loyal. "There are sides of Rosalyn that the public doesn't see but I've seen," Dresselhaus noted in a 2002 interview. As an example, Dresselhaus recalled that after college but still very early in her career, Yalow would, whenever possible, bring her husband, Aaron, to Dresselhaus' brief, ten-minute American Physical Society talks—along with shopping bags brimming with goodies. "She can be very motherly," Dresselhaus added.

Dresselhaus did take Yalow's exhortations to heart and changed her focus from education to physical sciences. Although she was fascinated with physics and chemistry, she continued as well with a strong mathematics course load and was seriously considering math as an alternate focus.

A scientist takes flight

Yalow left Hunter to pursue full-time research at the Bronx VA during Dresselhaus' junior year, but she encouraged Dresselhaus to apply for fellowships in research programs that would lead to graduate degrees. Of course, Dresselhaus was pulling her own weight, acing her courses and generally making it difficult for anyone without prejudice to turn her away.

With lavish praise from Yalow and other Hunter faculty, Dresselhaus secured several opportunities for advanced study as she neared graduation. She accepted a Fulbright fellowship in physics at Cambridge University in the UK and a spot in a graduate program at Radcliffe College.

On the evening of June 21, 1951, nearly a thousand young women and men gathered to celebrate the completion of their degrees earned at Hunter College. For most in the audience, the occasion marked the last stop in their formal education; for a rarefied few, it was just the beginning.

Dresselhaus was one of only five students in her class to graduate summa cum laude—with highest distinction. In her graduation program, she was listed with numerous honors. But perhaps the most memorable aspect of the day was her interaction with the ceremony's featured speaker: Mina Rees, director of mathematical sciences in the US Office of Naval Research and the future first female president of the American Association for the Advancement of Science (AAAS). After the ceremony, Rees congratulated Dresselhaus specifically. She passed on her strong approval of Dresselhaus' career plans, and encouraged her to continue with her studies. "It was," said Dresselhaus of the exchange, "a nice pat on the back."

Nearly four decades later, in 1990, Mildred Dresselhaus visited the White House to accept the U.S. Medal of Science from President George H.W. Bush, "for her studies of the electronic properties of metals and semimetals, and for her service to the nation in establishing a prominent place for women in physics and engineering." Yalow, her mentor, had won the award two years prior. In 1998, Dresselhaus followed in Rees' footsteps, becoming president of the AAAS, the ninth woman elected to that prestigious position. She would earn the nickname, "Queen of Carbon," for decades of work that expanded our understanding of materials, but she was equally known as a beloved professor who encouraged women and other underrepresented students in STEM.

As a budding scholar, Dresselhaus benefited greatly from the philosophy of her alma mater, Hunter College: "I learned a lot of things there, in terms of the responsibility of an individual to society, that it's not enough to only take, but you have to give," she said. In the give-and-take of academic mentorship, Dresselhaus received much from her interaction with the inspiring Rosalyn Yalow—and to the world she gave much in return.

Scientists have found the oldest known ancestor of octopuses – an approximately 330 million-year-old fossil unearthed in Montana.

The researchers concluded the  lived millions of years earlier than previously believed, meaning that octopuses originated before the era of dinosaurs.

The 4.7-inch (12-centimeter) fossil has 10 limbs—modern octopuses have eight—each with two rows of suckers. It probably lived in a shallow, tropical ocean bay.

"It's very rare to find soft tissue fossils, except in a few places," said Mike Vecchione, a Smithsonian National Museum of Natural History zoologist who was not involved in the study. "This is a very exciting finding. It pushes back the ancestry much farther than previously known."

The specimen was discovered in Montana's Bear Gulch limestone formation and donated to the Royal Ontario Museum in Canada in 1988.

For decades, the fossil sat overlooked in a drawer while scientists studied fossil sharks and other finds from the site. But then paleontologists noticed the 10 tiny limbs encased in limestone.

The well-preserved fossil also "shows some evidence of an ink sac," probably used to squirt out a dark liquid cloak to help to evade predators, just like modern octopuses, said Christopher Whalen, an American Museum of Natural History paleontologist and co-author of the study published Tuesday in the journal Nature Communications.

The creature, a vampyropod, was likely the ancestor of both modern octopuses and , a confusingly named marine critter that's much closer to an octopus than a squid. Previously, the "oldest known definitive" vampyropod was from around 240 million years ago, the authors said.

The scientists named the fossil Syllipsimopodi bideni, after President Joe Biden.

Whether or not having an ancient octopus—or vampire squid—bearing your name is actually a compliment, the scientists say they intended admiration for the president's science and research priorities.New species of extinct vampire-squid–like cephalopod is the first of its kind with ten functional arms

EVEN CAVE PEOPLE LONGED FOR THE OLD DAYS: ANCIENT TOOL RECYCLING DRIVEN BY STONE-AGE SENTIMENTALITY

They just don't make hand axes like they used to.


By Cassidy Ward

Between comic book movies and the recent slate of live action adaptations of popular franchises from the ‘80s and ‘90s, nostalgia has become a multi-billion-dollar industry. Countless think pieces have explored why recent generations look back on the past so fondly, but the answer to that question might be older than we thought.

A recent study by Bar Efrati from the Department of Archaeology and Ancient Near East Cultures at Tel Aviv University, and colleagues, takes a hard look at flint tools crafted by prehistoric humans between 300,000 and 500,000 years ago. They found that ancient humans frequently recovered, restored, and recycled tools made by previous generations, not out of any sense of convenience, but because of nostalgia and sentimentality. Their findings were published in the journal Scientific Reports.

Scientists have known for a while that flint tools were reworked and reused at different times in the historical record. The best evidence for this behavior is a phenomenon known as double patina which, when found, clearly demonstrates the refashioning of the same piece of flint over time.

“In the case of flint, it basically creates a colorful layer which is different in texture, shine, and color from the actual color of the flint. It’s caused by sun exposure, running water, the properties of the flint itself, and the sediment it’s buried in,” Efrati told SYFY WIRE.

After a piece of flint is fashioned into a tool, its surface begins acquiring that patina. It might be used for a time and then discarded as the individual or group using it moves on. Sometime later, it might be found by another group or individual and reshaped. The reshaping process removes the patina in some places, revealing the natural surface of the flint again. When scientists find flint tools today, they can clearly see two distinct patina patterns, indicating that a tool was recycled.

What was previously unclear was why ancient humans were gathering and recycling old tools. One possible reason is pure convenience. Why build a tool from scratch, if there’s a pretty good one sitting in front of you that just needs a little cleaning up? Efrati indicated that convenience likely played a part in why prehistoric humans recycled tools, but probably wasn’t the main reason.

Another reason tools might be recycled is if raw materials are in short supply, but that wasn’t the case at the Revadim open-air site on the southern coastal plain of Israel, where this study was carried out. In fact, there is still a robust supply of fresh flint available at the site today.

“Revadim was rich with flint,” Efrati said. “Fresh flint was the main way they chose to make their tools. Recycling of old items was happening together with the making of fresh ones, but fresh tools were dominant in terms of quantity.”

The distribution of new versus recycled clearly demonstrates that the people in the area knew how to make new tools, had plenty of raw materials available, and preferred making new tools to recycling old ones. If it was truly more convenient to recycle an old tool then we might expect that to be the dominant form discovered at the site, but that isn’t the case.

“There was more than just the function that made them collect and use tools again. The sentimentality, the recognition of someone else making something. They chose to recycle them,” Efrati said.

Researchers also found that recycled tools were minimally reshaped. In most cases, individuals found tools which were already the right size and shape for what they needed, and the modifications were minor. The implication is not only that ancient peoples recognized and appreciated the work of their own ancestors, but they took pains to preserve the initial form of the tools as much as possible.

In some ways, it’s the ancient equivalent of watching your favorite childhood cartoons on the VHS tape you recorded off the family TV, complete with Super Soaker and Lunchables commercials because that’s the way they were meant to be seen.

WORM MOON: YOU NEED TO SEE THE LAST FULL MOON OF WINTER THIS MONTH



The harbinger of spring.

ELIZABETH HOWELL


MARCH’S Full Moon falls just two days before spring arrives in the northern hemisphere. It will probably still be frosty outside in northern parts of the United States, but the Moon is still worth a few shivers for the view.

Watch for this month’s Worm Moon on March 18. If you’re clouded out or otherwise unavailable that night, the Moon will still look nearly full if you look at the sky the night before or the night after.

WHAT IS THE WORM MOON?

March’s Full Moon is most commonly called the Worm Moon, but there are a lot of spring-type names associated with this month’s Moon. Depending on the North American tribe tradition you follow, you may also call it the Crow Moon, the Crust Moon (referring to crusty, springtime snow), or the Sap or Sugar Moon (referring to the best time to harvest sap or sugar from trees).

As you can tell, the United States has a tradition of naming its Full Moons after the monikers from various Native American Tribes. These names became more widely known to non-Native Americans in the 1930s, when the Old Farmer’s Almanac began publishing weather forecasts and astronomical discussions for newer American settlers.

To be sure, different world cultures have different associations for the March Moon, so you may use another name for the Full Moon. Even the Worm Moon’s naming is very particular; NASA says that it was only the more southern United States tribes that called the March Full Moon a Worm Moon, which makes sense when you think about it. Worms can’t be active in frosty weather.

HOW TO SEE THE MARCH 2022 FULL MOON

The Full Moon reaches its peak brightness at 3:17 a.m. Eastern on Friday, March 18, which gives everyone a great astronomical treat at nightfall to enjoy during the weekend.

Full Moons stay above the local horizon all night, and with March’s still short days you’ll have many hours to enjoy the view. The Moon will appear nearly full the day before and the day after its official Full Moon phase, so if you’re lucky you might get a few nights of moongazing.

HOW MUCH BRIGHTER IS THE MOON DURING A FULL MOON?

Full Moons happen when the Moon, in its 27-day orbit around the Earth, arrives at a point in its path during where it’s directly opposite the Sun. Naturally, the Earth is in between the Sun and the Moon at this time, which can occasionally lead to a lunar eclipse. This time, however, the Sun’s light will flow around the Earth and fall upon the face of the Moon.

A Full Moon, at magnitude -12.92, is six times brighter than a Half Moon. You admittedly won’t see much else in the sky when the Moon is full. You will still spot bright stars such as Sirius (-1.46) and the various planets visible this month (such as Venus, Jupiter, and Saturn) — but the only thing outshining the Full Moon in our sky will be the Sun.

WHEN IS THE NEXT FULL MOON?

The Moon’s 27-day orbit is slightly less than the length of every Gregorian calendar month, the calendar system the United States and most other countries use. This timing oddity means that sometimes we can see more than one Full Moon in a month, and more than 12 Moons in a year. Neither will happen in 2022, though.

April’s single Full Moon will still be a fun show to watch. The Pink Moon reaches its peak on Saturday, April 16 at 2:55 p.m. Eastern.


Forget mammoths, study shows how to resurrect Christmas Island rats

A team of researchers used the brown rat, commonly used in lab experiments and seen in
 this photo, as a modern reference species to help reconstruct the genome of the extinct 
Christmas Island rat.

Ever since the movie Jurassic Park, the idea of bringing extinct animals back to life has captured the public's imagination—but what might scientists turn their attention towards first?

Instead of focusing on iconic species like the woolly mammoth or the Tasmanian tiger, a team of paleogeneticists have studied how, using gene editing, they could resurrect the humble Christmas Island rat, which died out around 120 years ago.

Though they did not follow through and create a living specimen, they say their paper, published in Current Biology on Wednesday, demonstrates just how close scientists working on de-extinction projects could actually get using current technology.

"I am not doing de-extinction, but I think it's a really interesting idea, and technically it's really exciting," senior author Tom Gilbert, an evolutionary geneticist at the University of Copenhagen, told AFP.

There are three pathways to bringing back extinct animals: back-breeding related species to achieve lost traits; cloning, which was used to create Dolly the sheep in 1996; and finally genetic editing, which Gilbert and colleagues looked at.

The idea is to take surviving DNA of an extinct species, and compare it to the genome of a closely-related modern species, then use techniques like CRISPR to edit the modern species' genome in the places where it differs.

The edited cells could then be used to create an embryo implanted in a surrogate host.

Gilbert said old DNA was like a book that has gone through a shredder, while the genome of a modern species is like an intact "reference book" that can be used to piece together the fragments of its degraded counterpart.

His interest in Christmas Island rats was piqued when a colleague studied their skins to look for evidence of pathogens that caused their extinction around 1900.

It's thought that black rats brought on European ships wiped out the native species, described in an 1887 entry of the Proceedings of the Zoological Society of London as a "fine new Rat," large in size with a long yellow-tipped tail and small rounded ears.

Key functions lost

The team used brown rats, commonly used in lab experiments, as the modern reference species, and found they could reconstruct 95 percent of the Christmas Island rat genome.

That may sound like a big success, but the five percent they couldn't recover was from regions of the genome that controlled smell and immunity, meaning that the recovered rat might look the same but would lack key functionality.

"The take home is, even if we have basically the perfect ancient DNA situation, we've got a really good sample, we've sequenced the hell out of it, we're still lacking five percent of it," said Gilbert.

The two species diverged around 2.6 million years ago: close in evolutionary time, but not close enough to fully reconstruct the lost species' full genome.

This has important implications for de-extinction efforts, such as a project by US bioscience firm Colossal to resurrect the mammoth, which died out around 4,000 years ago.

Mammoths have roughly the same evolutionary distance from modern elephants as brown rats and Christmas Island rats.

Teams in Australia meanwhile are looking at reviving the Tasmanian tiger, or thylacine, whose last surviving member died in captivity in 1936.

Even if gene-editing were perfected, replica animals created with the technique would thus have certain critical deficiencies.

"Let's say you're bringing back a mammoth solely to have a hairy elephant in a zoo to raise money or get conservation awareness—it doesn't really matter," he said.

But if the goal is to bring back the animal in its exact original form "that's never going to happen," he said.

Gilbert admitted that, while the science was fascinating, he had mixed feelings on de-extinction projects.

"I'm not convinced it is the best use of anyone's money," he said. "If you had to choose between bringing back something or protecting what was left, I'd put my money into protection."

The East Village Other

The East Village Other, a countercultural newspaper founded in 1965, published interviews with Timothy Leary and Allen Ginsberg.

The East Village Other (EVO) was founded in 1967 by a number of people who became well-known authors of the Underground Press: Allan Katzman, Walter Bowart, and John Wilcock. At its peak, the paper published 60,000 copies of individual papers. The EVO blends psychedelic interests with revolutionary politics. It regularly published interviews with Timothy Leary and Allen Ginsberg. It also became known for the sex ads that populated much of the back of the newspaper.

One regular column featured the images and biographies of East Village females. Titled “Slumgoddess,” the column regularly depicted scantily-clad (and often nude) images of local, sexually liberated and counterculturally inclined women. Although the subject of much controversy, Allan Katman felt that the sex ads in the back of the paper played an important role for the “lonely people of New York,” who relied on the paper for human companionship. The paper also became well-known for publishing underground comics. Well known artists like R. Crumb and Art Spiegelman published work with the EVO.

From Volume 1, Issue 12

The EVO was largely responsible for initiating the Underground Press Syndicate (UPS), a nation-wide syndication network that made it possible for papers in small towns to emerge all over the country. In May 1966, the East Village Other began a column that would be syndicated across the country in five other underground papers. Timothy Leary started the column “Tune in / Turn on / Drop out” in part to help his defense in a recent drug charge. Leary intended to help readers achieve consciousness expansion without the use of drugs. The column was short lived, but appears to have sparked the idea for the UPS. Allan Katzman suggested the more explicit idea for an underground syndicate in the EVO in June 1966. Walter Bowart of the EVO claimed to have come up with the name spontaneously. After seeing a United Parcel Service truck drive by during an interview he replied, “We’re… ah… UPS – the Underground Press Syndicate.”
The paper is an excellent resource for anyone studying the personalities and events characteristic of the American counterculture.

For a small fee, papers in the UPS could reprint any articles from any other members’ papers free of charge. This provided enough content for underground publishers in small cities and towns to produce a paper. The idea that editors could reprint any article from other member papers reflected a belief popular among underground authors and writers that copyright laws were obtrusive and out of date.

Because of the EVO’s longevity (it lasted until 1972), popularity, location, and role in the UPS, the paper is an excellent resource for anyone studying the personalities and events characteristic of the American counterculture. The EVO carried on a close relationship with Timothy Leary. As the counterculture was amping up in the late 1960s, Leary was finishing his time at the Millbrook estate in upstate New York where he was running “experiments” with LSD. The paper followed closely his numerous run-ins with the law, advertised on behalf of the campaign to raise bail when he was finally arrested, and when the Weather Underground broke Leary out of a California prison, the EVO announced on its cover, “Proud Eagle Flies Free.” (September 15, 1970).

The cover of Volume 4, Issue 38

The EVO is also an excellent resource for documentation of countercultural events. Take the March on Washington, where tens of thousands of activists stormed and occupied the front steps of the Pentagon. The paper helped Ed Sanders, a member of the band The Fugs and an owner of the Peace Eye Bookstore, raise funds to perform the Exorcism of the Pentagon that took place at the march. Perhaps because of its proximity, the EVO advertised and documented to a greater extent than many other papers the best-known countercultural event, Woodstock, also known as “The Aquarian Exposition.” The paper printed advertisements for the festival and a thorough review of the event by John Hilgerdt (August 13, 1969, August 20, 1969). For Hilgerdt, Woodstock was only the beginning of a mass countercultural movement. He writes, “A few thousand of the absolutely most together and peaceful and beautiful heads in the world are gathered in a grand tribal new beginning… All the petty bullshit that before kept us apart vanished and for the first time we were free” (August 20, 1969, 7).

The EVO provides documentation of the activities of one of the most active countercultural communities in the US in New York’s East Village. Although there were remnants of the counterculture that lived on after the EVO had closed its doors, by the time the paper ceased publication, the countercultural movement had already begun to fade. Because the paper was one of the earliest underground papers, and because its lifespan covers the rise and fall of the counterculture, the paper is a good resource for gauging the general attitudes of the counterculture. It’s an excellent resource for those studying the aesthetics of the counterculture, especially comics, and its proximity to New York and role in the UPS make it an excellent reference for those interested in countercultural leaders and in many of the events that have become emblematic of the counterculture more generally.

Terence McKenna’s Anarchic Psychedelic Religion

Terence McKenna was an evangelist for the use of psilocybin and other mind-altering drugs, as a way to transcend and escape “untrammeled rationalism.”

With several companies seeking FDA approval for the medical use of psilocybin, and Oregon set to legalize it next year, the “magic mushroom” drug is increasingly mainstream. Yet, as religion scholar Andrew Monteith writes, the subculture in which psilocybin became popular in the US drew a central sense of its identity from opposition to the dominant culture. And no figure better epitomizes this than Terence McKenna. Monteith argues that McKenna made psilocybin and other mind-altering drugs the center of an enormously influential movement that was (and continues to be) both a religion and a radical political philosophy.

McKenna entered the world of psychedelics—or entheogens, a term Monteith prefers for its more spiritual connotations—at a time when the popular perception of the psychedelic poster child, LSD, was shifting. The drug had initially emerged as a pharmaceutical product that medical researchers believed had enormous potential. But by the mid-1960s it was becoming associated with youth unrest, antisocial behavior, and a lack of cohesion among US troops fighting in Vietnam.
McKenna wrote that “untrammeled rationalism, male dominance, and attention to the visible surface of things” had rendered society “very, very sick.”

Starting in 1965, McKenna studied ethnobotany at the University of California Berkeley, while also using substances such as LSD and DMT (the main ingredient in ayahuasca).

In 1976, McKenna and his brother Dennis anonymously published a guide to growing psychoactive psilocybin mushrooms. The book argues that mushrooms were the source of humanity’s first religious ideas and that entheogens would lead to “the next evolutionary step” for humanity.

Monteith writes that, in McKenna’s view, it was no coincidence that dominant political forces opposed such a substance. He believed that early human societies had been egalitarian and embraced consciousness-altering medicines. Then came the rise of “dominator culture” and patriarchal monotheism. These systems despised entheogens for the way they allowed people to transcend their individual egos.

McKenna wrote that “untrammeled rationalism, male dominance, and attention to the visible surface of things” had rendered society “very, very sick.” His solution was “Anarchic Revival,” encompassing both spiritual connection to the natural world and new, egalitarian social structures.

McKenna mingled scientific and pseudoscientific ideas about plant medicines and human consciousness. He cited real academic scholars in explaining his views of human history. But many of his ideas came from things that he and other “Psychonauts” had experienced while using entheogens. In his cosmology, psilocybin mushrooms were understood as sentient entities from space that can communicate with those who eat them. DMT, meanwhile, could allow people to visit a realm populated by “machine elves” capable of teaching humanity new forms of communication.

Since McKenna’s death in 2000, Psychonauts have distributed his recorded lectures and writings widely on the internet. Some on Reddit and other forums discuss connections between his words and their own experiences with entheogens. Some create art featuring the man, which Monteith suggests may sometimes function as icons like paintings of a saint, used in devotional practices involving entheogens.

Today, it remains an open question how this counterculture will adapt, as psychedelics become increasingly acceptable to a dominant society that once tried to eliminate them.

The USDA Versus Black Farmers

Current attempts to correct historical discrimination by local and regional offices of the USDA have been met with charges of “reverse discrimination.”

Debt relief for Black farmers, part of the American Rescue Plan, has been blocked by a lawsuit by white farmers who are charging “reverse discrimination.”

The issue brings up the extraordinary history of the US Department of Agriculture’s decades of denial of federal benefits to Black farmers, even after the civil rights laws of the 1960s. As scholar Pete Daniel writes,“racism circulated through federal, state, and county USDA offices, and employees at every level bent civil rights laws and subverted governmental programs in order to punish black farmers.”
Battles over school desegregation, public transportation and accommodations, and, of course, voting rights were news. Farmers were not.

Black farmers thus “suffered their most debilitating discrimination during the civil rights era when laws supposedly protected them from racist policies.” One reason is that little attention was paid to their plight in coverage of the civil rights struggle. Battles over school desegregation, public transportation and accommodations, and, of course, voting rights were news. Farmers were not.

Another reason was the massive resistance of segregationists. It’s one thing to make federal laws, but quite another to enforce them locally when those who are supposed to implement them are themselves the enforcers and beneficiaries of Jim Crow.

“The decline of black farmers after World War II contrasted dismally with their gains in the half century after emancipation when, demonstrating tremendous energy and sagacity, they negotiated a maze of race law and custom and—during the harshest years of segregation, peonage, and violence—gained land and status in southern communities.”

The USDA is extraordinarily powerful, the source of “allotments, credit, information, and access to government largess.” Formed during the Civil War, the Department’s programs were much expanded by the New Deal. From then into the 1990s, vital USDA programs like the Farmers Home Administration (FHA; later the FmHA), the Agricultural Stabilization and Conservation Service (ASCS), and the Federal Extension Service (FES), “bitterly resisted demands to share power with African Americans.”

The “tracks of racism and discrimination led from local committees and agriculture offices to state offices, to land-grant schools, to experimental stations, and on to Washington.” For instance, county-level bureaucrats punished Black farmers who advocated for civil rights, registered to vote, wanted to send their children to white schools, or joined the NAACP. “Denying production credit and home loans and chipping away at acreage allotments, committees drove activist farmers off the land.”

There was, of course, much movement from farms during the twentieth century. About one third of all workers in the US labored on farms in 1900. In 1950, it was less than a fifth of all workers. Today, a tenth of America’s workforce is in agriculture, food, and related industries, but most of this the food-services sector. Farming itself comprised a mere 1.4% of the U.S. labor force in 2020.

These declines were uneven: one 1965 study found that the white farmer population declined by 28% between 1935-1959. In the same time period, the Black farmer population declined 40%.

The USDA’s abysmal track record was revealed by a class-action suit settled in 1999. Pigford v. Glickman became one of the largest civil rights settlements ever. But it only reached back to the early 1980s. Thousands of Black farmers had been plunged into debt and driven from the land before that were out of luck.

One of the plaintiffs in Pigford was Shirley Sherrod. Her father, a Georgia farmer, had been shot dead by a white farmer in 1965. An all-white grand jury brought no charges against the killer. Sherrod joined the class action suit because she and her husband were denied USDA loans that were later shown to have been given to local white farmers on very generous terms.

In 2009, Sherrod was appointed the USDA’s rural development director for Georgia, the first Black person to hold that position. But she was forced to resign in 2010 over what turned out to be a doctored video released by right-wing activists that made it seem like she she was discriminating against white farmers.

Are Polar Bears Altruistic or Just Bad At Math?

Polar bear mothers are known to adopt and raise cubs from non-related litters. Why do they make a multi-year commitment to do it?

In the 21st century, most mentions of polar bears conjure images of stranded bears, on exposed beaches or drifting ice sheets as glaciers melt away into the ocean. The harsh conditions of the rapidly-changing Arctic don’t make it easy for animals to raise the next generation of youngsters, and raising a polar bear cub is a lot of work.

Polar bear moms must build a snow den in the fall, where they will stay, without food or water, to give birth and care for their newborn cubs through the winter. Polar bears usually give birth to litters of one or two cubs, and about 70% of cubs will survive–although this number is declining closer to 40% over time. In the spring, mom and cubs will emerge from the den, where she will spend the next 2.5-3 years showing them the ropes of Arctic living. Given this significant investment in her cubs, it’s surprising to find that polar bear moms will sometimes adopt additional cubs from another mother.
Many species care for young that aren’t their own, a natural phenomenon known as alloparenting or cooperative breeding.

This behavior isn’t uncommon throughout the animal kingdom–many species care for young that aren’t their own, a natural phenomenon known as alloparenting or cooperative breeding. In fact, some animals, like meerkats, are unable to raise young without the cooperation of helpers in the social group. Alloparenting most commonly evolves in group-living species, when individuals are highly related or very social. In these cases, animals pass on their shared genes by caring for more distant relatives or increase the chance of gaining reciprocal care for their future offspring. In this way, helpers benefit from their efforts, under the guise of a seemingly altruistic act.

However, polar bears do not meet any of these prerequisites for the evolution of alloparenting. They are solitary, live at low densities far from other groups, and raise cubs that impose a large energetic cost due to their prolonged care. So, why do they do it?

Western researchers have studied several populations of polar bears around the Arctic since the 1960’s, although Indigenous communities likely have traditional knowledge of polar bears that spans thousands of years. In this time, polar bears have been observed adopting a single unrelated cub into an existing litter, as well as adopting a litter of new cubs following the loss of their own cubs.

One possible explanation is that new moms gain valuable parenting experience through adoption, increasing the probability of success for a subsequent litter. But this doesn’t seem to be supported by research. The most likely explanation is that polar bears haven’t developed the cognitive ability to keep track of the number or identity of their own cubs. Solitary polar bears don’t cross paths very often, so it’s usually safe for a mother to assume that any cubs within an arm’s reach are hers… with the caveat that she won’t notice if one of her cubs has just wandered into the group and doesn’t belong. It’s also possible that mothers who have lost their own cubs recently are biologically predisposed to parenting, and will adopt any cubs that come her way as her own.

Either way, it looks like this curious case of cub adoption is just another example of an energetically costly mistake, rather than a heartwarming instance of altruism and concern. In the wild, it’s still every parent for themselves in the struggle to survive, and pass their genes to the next generation.
