The loss of employer-sponsored health insurance can be a serious concern for older people

Michael Kerr thought he would be back to work by now. When the 52-year-old from Reading, Pa., was put on furlough from his retail manager position in mid-March, he figured the business would reopen by April, reinstating him and other employees.
But as his furlough dragged on into June, he realized his  would become permanent, leaving him without income or his employer-sponsored health .
"I felt like I needed to cover myself in bubble wrap and stay in the house," he said. "Every ache and pain got a little bit more scary."
Kerr is one of millions of American workers who have lost their job-based health insurance during the COVID-19 pandemic. The Kaiser Family Foundation has estimated that 27 million Americans could lose their employer-sponsored insurance and become uninsured due to the pandemic. Older workers under age 65 are among the most vulnerable.
Those numbers are staggering to people such as Kerr, who not only have to pay higher premiums for health insurance as they get older but may also have a harder time finding a new job, even when the economy isn't in a recession. "The closer you get to 60, the more difficult and scary it gets," he said. "Even by then, you've still got five more years to muddle through before getting government assistance."
Stan Dorn, director of the National Center for Coverage Innovation for the consumer group Families U.S., says that loss of insurance among people in the age range of 45 to 64 can be dire, as they often have greater health costs in medications or chronic conditions. "These folks are more expensive for an employer than younger adults because the average cost of health insurance is more for them," he said. And that added cost could be "an extra incentive to get rid of them."
The loss of health insurance for this group and others could also have a severe impact on the economy, Dorn said.
"When patients don't come to the hospital because they don't have insurance anymore, that means revenue dries up," he noted. "And those hospitals, clinics, and other providers would have to lay off staff."
Dorn also fears that the economy will continue to see more layoffs into the fall, and with it, more people losing their job-based health insurance. He thinks that could lead some people to delay or go without the care they need simply because they can no longer afford it.
"Patients with chronic conditions won't be able to afford their prescriptions, or they'll cut their pills in half," he said. "We'll see more people playing Russian roulette with their lives."
When the Affordable Care Act was passed in 2010, it increased coverage in two ways: by expanding Medicaid for the poor and improving plans for individuals. For the latter, the act set up a system so that nearly 90% of applicants received subsidies that reduced monthly premiums. The act also increased insurance protections for consumers, by banning plans that had lifetime caps on coverage or didn't cover preexisting conditions. More than 20 million people were able to get insurance. But over time, the law's regulations have been weakened, making room for new and cheaper plans with lesser coverage to enter the marketplace.
When Kerr realized that his furlough would turn into a permanent layoff and that his benefits would come to an end, he tried to navigate the  marketplace on his own. But he quickly grew confused by the discrepancies in cost and coverage between all the available options.
"I almost made a bad decision on a plan that would've been more expensive and the coverage a lot less," he said of a plan through Oscar Health, which started providing coverage in the Philadelphia region only this year. "Health care really should be simplified somehow."
Kerr sought out the help of Young's Insurance Services, a health and life insurance brokerage agency based in Norristown. James Long, an agent there who frequently works with people in Kerr's age group, says that people in similar situations often have only two options: extend their employer-sponsored coverage by enrolling in COBRA, or find a plan through the marketplace and hope for discounts through subsidies. Long and agents like him are paid on commission, through marketing dollars incorporated into all policies.
Fortunately, Kerr qualified for some subsidies and was able to get an affordable plan through the marketplace, saving him from a COBRA option that was beyond his price range. But Long says that for people who are unable to receive subsidies, COBRA tends to be the better option.
Long often sees confusion among clients about how COBRA works. "Lots of people think it's its own health plan," he said. "But they're actually continuing on the same plan from their former employer, just now paying full price for it" without their employer's contribution.
That full price can lead to sticker shock, as Long notes that COBRA often falls in the range of $600 to $800 a month. Despite that jump in monthly cost, Long says that "equivalent plans on the marketplace without subsidies could be double that price."
David Grande, director of policy at the University of Pennsylvania's Leonard Davis Institute of Health Economics, agrees with Long that COBRA might be the best choice for some people. For a person to qualify for subsidies, he notes that a person's household income needs to be below 400% of the poverty level, or $86,880 for a family of three. "If you have the financial resources for COBRA, that's probably the best option."
Still, Grande bemoans the lack of federal intervention on health care, especially as pandemic-related economic damage grows more permanent. He thinks, like Kerr, that navigating the -care marketplace is too confusing, and that there's a lot of misunderstanding around who qualifies for subsidies and what the different options are.
"There needs to be a strong national effort to make subsidized coverage advertised, available, and easy to access," he said. "We're seeing the limits of the Affordable Care Act through individuals who don't qualify for subsidies, who probably should be subsidized at a point like this."
Some of the solutions Grande sees for these problems would be to expand Medicaid in states that haven't already done so, increasing the number of people who are able to enroll. (Pennsylvania and New Jersey have both expanded Medicaid.)
State-based exchanges, which Pennsylvania is set to begin in 2021, could help cut costs for individuals, as well, but he says that bigger issues surround who qualifies for subsidies. Those regulations can be changed only by the federal government, he noted.
Ellen Grubawsky, another client of Young's Insurance Services, also had to find new coverage after her furlough became a permanent layoff at a company where she had worked for 30 years. But at age 62, the Perkiomenville resident is more worried about securing a new job before becoming eligible for Medicare at 65.
"I'm uneasy about finding a job when the time comes, but I just have to wait and see what happens," she said.
Though Grubawsky qualified for subsidies that gave her discounted options, she says, the final added cost of almost $300 a month on her new plan is one more bill that's increasingly difficult to pay without a steady income. Worse yet, she has concerns that her new insurance has less coverage than her job-based plan. "I'm not even sure the plan I picked is the best one."
While enrolling in a new plan has made Grubawsky feel more secure about her situation, she still feels uncertain about her finances for the future. She hasn't ruled out collecting her Social Security early or considering a reverse mortgage (a loan that allows homeowners over 62 to draw out part of their home's equity as income) if the economy doesn't improve. Though she's still able to support herself through her severance package, Grubawsky acknowledged "that money only goes so far."
"It's very scary," she said. "I feel very uneasy about the whole situation.

1 in 5 tenants in L.A. County has struggled with rent during the pandemic

Twenty-two percent of Los Angeles County tenants paid rent late at least once from April to July and about 7% did not pay any rent at least once between May and July, according to a joint UCLA-USC report released Monday as a statewide eviction moratorium is set to expire.


The report documents hardships like unpaid  that tenants are facing during the COVID-19 pandemic and traces those hardships overwhelmingly to lost work and wages as a result of the economic shutdown.
Among households in the county that did not pay rent, either in full or partially, about 98,000 tenants have been threatened with  while an additional 40,000 report that their landlord has already begun eviction proceedings against them. California's moratorium on evictions is scheduled to end Tuesday, but lawmakers are considering a bill that would extend certain protections through Jan. 31.
Researchers at the UCLA Lewis Center for Regional Policy Studies and the USC Lusk Center for Real Estate analyzed data from the U.S. Census, as well as from an original survey of 1,000 Los Angeles County renter households conducted in July . The survey, in particular, gave researchers new insights into the circumstances facing L.A. renters. The study was authored by Michael Manville, Paavo Monkkonen and Michael Lens of the UCLA Luskin School of Public Affairs and Richard Green, director of the USC Lusk Center.
"I think everyone understood, early on, that renters might be in trouble as a result of COVID-19 and its economic fallout, but conventional sources of data don't give us a good window into whether renters are paying or not, and into how they are paying if they do pay," said lead author Manville, an associate professor of urban planning.
"We were able, by using data from a special census survey and especially our own original survey of renters, to get a direct sense of these questions."
The researchers first analyzed the U.S. Census Bureau's Household Pulse Survey, a weekly survey that asked if renters have paid rent on time and if they think they will be able to pay the next month's rent on time. This data was augmented by the UCLA-USC survey, which asked not only if renters paid on time but if they paid in full and if they were threatened with an eviction or had eviction proceedings initiated against them.
The study found that tenants have been facing unprecedented hardships during the COVID-19 crisis, substantially more so than homeowners. Overall, the study also found that most tenants are still paying their rent during the pandemic but are often doing so by relying on unconventional funding sources. The majority who pay late or not at all have either lost their work, gotten sick with COVID-19 or both.
New study highlights tenants' financial peril as evictions loom
Among the findings:
  • About 16% of tenants report paying rent late each month from April through July.
  • About 10% did not pay rent in full for at least one month between May and July.
  • About 2% of renters are three full months behind on rent. This translates to almost 40,000 households in a deep financial hole.
  • Late payment and nonpayment are strongly associated with very low incomes (households earning less than $25,000 annually) and being Black or Hispanic.
  • Nonpayment is more common among tenants who rent from friends and family.
  • This crisis is particularly acute in the Los Angeles region and other high-cost cities, where an existing affordable housing crisis and an economic slowdown resulting from mitigation efforts to curb the pandemic intersect to threaten the stability of many households.
"Even before the pandemic, L.A. renters, especially low-income renters, were struggling," said Lens, associate faculty director of the UCLA Lewis Center. And while most renters who miss rent have entered into some type of repayment plan, they're not out of the woods yet.
"Nonpayment occurs disproportionately among the lowest-income renter households, so repaying back rent could be a tremendous burden for them," he added.
The study also found that renters were suffering disproportionately from anxiety, depression and food scarcity, and they are relying much more than in the past on , family and friends, and payday loans to cover their expenses. One-third of households with problems paying rent relied on credit card debt and about 40% used emergency payday loans.
The prevalence of these nonconventional forms of payment, along with the incidence of job loss among tenants, suggests the importance of direct income assistance to renter households.
Tenants collecting unemployment insurance were 39% less likely to miss rent payments. Just 5% of households that hadn't lost a job or fallen sick reported not paying rent.
Government assistance can help tenants pay rent—and more—amid pandemic
Green noted that, although data show that most renters have been paying their rent, government policies can help strengthen the ability to do so.
"One of the main concerns among landlords at the beginning of the pandemic was that tenants weren't going to pay their rent if they knew they weren't going to be evicted," he said. "Not only have we not seen any evidence of this, but getting money in renters' hands through  or rental assistance helps a lot."
Monkkonen, an associate professor of urban planning and public policy, agreed. Helping renters now will not only stave off looming evictions next month but "also prevent cumulative money problems that are no less serious, such as renters struggling to pay back credit card debt, struggling to manage a repayment plan or emerging from the pandemic with little savings left," he said.
Across the state, most evictions were halted in April by the California Judicial Council, the state's court policymaking body.
The eviction moratorium was set to expire in June, but that was postponed to Sept. 1 to allow local and state lawmakers more time to develop further protections, including the bill currently under consideration. Given the unconventional means renters reported using to pay rent, the new study says that policies providing funds to renters could help mitigate a swath of evictions and homelessness that had been predicted by previous reports by researchers at UCLA and elsewhere

Fish invasions follow Panama and Suez canal expansions

by Smithsonian Tropical Research Institute

World maritime trade grows each year, aided by canal waterways that connect oceans and reduce shipping time, energy consumption and carbon emissions. Following recent expansions of the Panama and Suez canals, non-native fish species are invading new habitats according to a new report in Nature Ecology and Evolution by researchers at the Smithsonian Tropical Research Institute (STRI) in Panama and the Leibnitz Center for Tropical Marine Research (ZMT) in Germany.

"We're seeing a shift from predominantly freshwater fishes to marine fishes in the Panama Canal (Lake Gatun) in a short period of time," said Mark Torchin, STRI marine ecologist. "The concern is that if fish invasions continue there is a good chance of some of those fishes moving into the other ocean, with unknown environmental consequences."

Larger locks to allow transit of NeoPanamax vessels (NeoPanamax refers to ships too big to pass through the original 1914 locks) through the Panama Canal were finished in 2016. Expansion of the Suez Canal to include a new, 35-kilometer channel concluded in 2015.

"During the planning phases of both projects, researchers warned about the risks of expanding these two canals," said Gustavo Castellanos-Galindo, postdoctoral fellow at STRI and guest scientist at ZMT. "This report documents those changes in real time."

Only four years after the Panama Canal expansion, long-term monitoring recorded the presence of 11 new marine fish species in Lake Gatun, which has served as a freshwater barrier to movement of marine fauna between Pacific and Atlantic Oceans since the canal opened in 1914. This takes the total number of marine fish species known from in the lake from 18 to 29. Marine fishes such as jacks, snooks, mojarras and ladyfish have entirely replaced freshwater fishes in some parts of the lake.

Salinity in the lake increased, although the cause has not yet been determined. Possibilities include increased ship traffic and lock usage and the new locks' design, which incorporates recirculation of some lockage water.

"These marine fish invasions are an early warning sign of what could happen if no corrective measures are taken," Castellanos-Galindo said. "Along both coasts of Panama there are hundreds of fish species that could tolerate the conditions of an even slightly brackish canal. We don't know what the ecological and socioeconomic consequences of these fishes crossing the canal to either the Pacific or the Atlantic would be."

"We can document the Panama Canal invasions because we have good, standardized and quantitative pre-expansion data," said D. Ross Robertson, STRI ichthyologist. "We need to get back out there to collect more data to find out exactly what is going on and to provide the science that will help policy makers mitigate the potential impact. This is a really good example of how the pandemic has interrupted field work with important implications for environmental decision making."

Whereas the barrier to fish crossing from ocean to ocean in Panama is a freshwater lake, in the Suez waterway, the Bitter Lakes were originally saltier than the Mediterranean and Red Sea, which also limited species movement. Nonetheless, throughout the history of the Suez Canal, more than 400 non-native animal species, including more than 100 species of marine fishes from the Red Sea, have entered the Mediterranean. With canal expansion, increased water flow diluted the lakes and eight new fish species entered the Mediterranean during the past five years.

Because fees for shipping through the canals account for roughly 10% of the gross domestic product in Panama and in Egypt, there is an economic incentive to continue to increase shipping traffic through the canals. The authors suggest creative, science-based solutions to limit environmental and socioeconomic damage. They propose that the UN Decade of Ocean Science for Sustainable Development (2021-2030) may provide the ideal opportunity for ensuring that the canals are included in international maritime policy to limit the environmental and economic impacts of invasive species. In addition, because policy changes can take a long time to implement, they also suggest that the shipping industry could proactively address this issue.

The UN agency responsible for sustainable shipping, the International Maritime Organization, has implemented guidelines and obligations to reduce the spread of non-native species through ballast water—but they do not apply specifically to the canals.

In the case of the Suez Canal, it may be possible to use the hypersaline effluent from desalinization plants to make the Bitter Lakes saltier again, with the caveat that this alternative should be studied carefully before implementing. In both cases, sophisticated monitoring tools—using DNA in water samples to generate lists of the species detected and using sound to detect invaders, may help to catch invaders early before they establish large populations. Technology may also be put to work to directly address invasion by means of acoustic and/or electric barriers to deter invaders.

The authors hope that all of the stakeholders will recognize the importance of having the best scientific data in hand as they design new policy and mitigation measures.

How tadpoles provide insight into pandemics 

by Sara Putnam,  


How tadpoles provide insight into pandemics

A virus affecting wood frog tadpoles throughout the eastern United States is offering scientists a rare opportunity to investigate the role of environmental factors in the spread of infectious disease.


An important aspect of controlling the spread of any virus is understanding how the virus, or agent, is transmitted through the environment to the host. Scientists refer to the trio of agent, host, and environment as the epidemiological triangle or triad. In the COVID-19 pandemic, the agent is the SARS-CoV-2 virus, humans are the , and the environment now includes ecosystems throughout the planet. Scientists have made strides in understanding the nature of the SARS-CoV-2 virus and the infection it causes in its human hosts, and they have identified variables in the host population that can cause some individuals to be more severely affected by the virus than others. As researchers continue to learn about  that facilitate the spread of COVID-19, we practice social distancing and wear masks to contain airborne droplets from our mouths and noses.
The interrelationships among agent, host, and environment are complex, and possible variables in each of the three are limitless, making it impossible, when studying them as a system, to tease out the differential effects of the individual players. While agent and host can be studied in isolation and in direct relationship to each other within the laboratory, environmental factors also play a role in disease dynamics, meaning that any conclusions reached will not fully reflect that happens in . However, Associate Professor Tracy Rittenhouse has developed an experimental model where the focus is the effects of the environment in epidemics rather than the details of the agent and host interaction.
Several years ago, Rittenhouse, a faculty member in the Department of Natural Resources and the Environment, learned of wood frog tadpole dieoffs in northeastern Connecticut that had been found to be caused by Ranavirus Frog virus 3 (FV3). To measure the prevalence of FV3 in the area, Rittenhouse harvested tadpoles from numerous wetlands over a two-year period and found that the frog virus was much more widespread than previously known. But, the population of wood frogs, a species known to be particularly susceptible to FV3, did not appear to be declining, and some live tadpoles harvested from wetlands were found to be infected with the virus, both of which indicated that the virus was not always lethal.
From her surveys, Rittenhouse learned that when tadpole dieoffs did occur, it was often at the same developmental stage, just before metamorphosis. The carcasses would remain visible in the water for only one to three days. The tadpole carcasses decomposed so quickly it was if they had disappeared. Determining whether tadpoles died and decomposed or metamorphosed into frogs and left the wetland would have required simultaneously monitoring all wetlands where the virus was known to be present, which was not feasible.
Says Rittenhouse, "We don't have a good explanation for why we could have found the virus so commonly and not have dieoff events. I think there's some middle ground. I believe there are more dieoff events happening than we're detecting, but we don't yet know what triggers them. We're concerned that changes occurring in , such as salinity levels or temperature, might be increasing the likelihood of dieoffs." An additional question is whether the tadpoles are particularly susceptible at the stage when dieoffs have occurred, or if something occurs in the environment at that time.
A fruitful collaboration
The study of interactions among agent, host, and environment is best done with a collaborative approach incorporating a range of expertise. Says Rittenhouse, "I study populations. I know a lot about wood frogs–I know where wood frogs live, what types of environments they live in, what causes high survival, and what causes low survival. But I'm not a disease expert." So, she teamed up with Jesse Brunner, a disease ecologist, and Erica Crespi, a physiologist, both at Washington State University, who have studied Ranavirus and its effects on individual tadpoles. Brunner specializes in the relationship between Ranavirus and its host, while Crespi is an expert on tadpole health.
Rittenhouse devised a set of experiments in which two environmental stress factors—salinity and temperature—are manipulated to identify what, if any role, they play in triggering dieoffs related to FV3. Says Rittenhouse, "Road salt and temperature are two environmental conditions that we're manipulating because they're common things in the environment, and they are both changing a lot, regionally and globally. Salinization of our fresh waters is a very hot topic because it's happening along our coastlines. As sea level rises, there's saltwater intrusion into freshwater systems and into terrestrial environments. But that's also happening in forests in terrestrial conditions when we add road salt to our roads, and it runs off into freshwater wetlands and streams."
During the spring of 2019, Rittenhouse built outdoor experimental systems called mesocosms, which simulate the natural environment but allow for the control of some factors. She set up 150 fifty-gallon tanks, each of which, when filled with water, leaf litter and tadpoles, represents a wetland. These wetlands received natural rainfall, nutrient inputs from the air (think oak tree pollen in the spring), and daily temperature fluctuations as the sun rose and set. She controlled for variables in the virus and host: Egg masses from different wetlands were mixed to create heterogeneous but similar populations for each tank, and Brunner isolated and extracted the virus from samples Rittenhouse collected in the wild. Finally, one tadpole infected with FV3 was added to each tank. In her experiments, Rittenhouse manipulated the temperature and salinity levels of some tanks and maintained some tanks as controls.
Rittenhouse, Brunner, and Crespi had developed hypotheses for expected mortality rates in response to the environmental manipulations. As the tadpoles matured, Rittenhouse and the students in her lab group monitored all the tadpoles in every tank, every day during May and June 2019. The result was more than twenty epidemiological curves for each temperature-salt combination.
"What our project brings is the ability to manipulate a population and see how changes to environmental conditions change how spiked or flat an epidemic curve is," Rittenhouse says. "And there really are not a lot of study systems where you can manipulate that epidemic curve. Much of what we know about disease epidemics is based on mathematical models. Our project uses a study system where we can manipulate a population and quantify an epidemic curve in a two-to-three-month period for 150 populations, but it's real data from real animals. It's a way to confirm that some of our mathematical models are correct."
Ironically, the studies Rittenhouse planned for continuing the FV3 research during the summer of 2020 had to be postponed due to the COVID-19 pandemic. The experiments would have required eight undergraduate student research assistants working together every day to monitor tadpole mortality. So, like everyone else, Rittenhouse pivoted. No frog virus was put into the tanks. Instead she and one graduate student focused their efforts on finely tuned manipulations of salt and temperature in the absence of the .
Next spring, when more is known about how people can work safely in a world with COVID, then Rittenhouse and her students will return to her NSF- funded research on Ranavirus epidemics.
Rittenhouse says, "Each spring in my population dynamics course, I teach students how to use data we collect in the wild, counting animals, to develop estimates of birth rates, death rates, survival rates. We take those estimates and build population-level models that predict if a population is going to increase or decrease over time and link that to trends we observe in the wild. But in this case, the cool thing is we can create all these experimental populations—150 different populations—and we can measure the population response. How peaked was the curve? How flat was the curve? What's the timespan between the beginning and end of the epidemic? How do changes in environmental conditions that might be stressful for individuals or populations change the shape of an epidemic curve?"

Probing the origin of the mantle's chemically distinct 'scars'

by Carnegie Institution for Science
Basalt, the most-common rock on Earth’s surface, encases green crystals--a geologic "nesting doll" phenomenon called a xenolith. Basalts such as this one derive from a section of the mantle that has been depleted in incompatible trace elements, which is usually attributed to continental crust formation. In their work, Tucker and his collaborators propose another mechanism that would impart this signature. Credit: Carnegie Institution for Science

The composition of Earth's mantle was more shaped by interactions with the oceanic crust than previously thought, according to work from Carnegie's Jonathan Tucker and Peter van Keken along with colleagues from Oxford that was recently published in Geochemistry, Geophysics, Geosystems.

During its evolution, our planet separated into distinct layers—core, mantle, and crust. Each has its own composition and the dynamic processes through which these layers interact with their neighbors can teach us about Earth's geologic history.

Plate tectonic processes allow for continuous evolution of the crust and play a key role in our planet's habitability. Earth has two kinds of tectonic plates: those that host continents, which have survived for billions of years, and those that are mostly covered by oceans. Oceanic plates are created by the upward motion of mantle material that occurs when plates spread apart. They are destroyed by sliding under continental plates and back into the mantle, a process that also forms new continental crust.

"The chemical composition of the mantle is influenced by continent formation and geoscientists can read chemical markers left behind by this process," Tucker explained.

For example, some of the elements found in crustal rocks don't play nicely with the mantle's minerals. When continental crust formation draws these elements out of the mantle, they leave behind a depleted residue, like sucking the juice out of a Sno-Cone and leaving just ice. This is referred to as crust extraction and is usually thought to create "scars" that are easy to spot and identify in rocks. It also leaves behind distinct zones in the mantle that are depleted of these particular elements.

"It's long been thought that these chemical scars are the product of crust formation," Tucker explained. "But mantle's inaccessibility means that it's difficult to know for sure using rock and mineral samples alone."

To probe the question of the origin of these depleted reservoirs in the mantle, Tucker, van Keken, and their Oxford colleagues Rosemary Jones and Chris Ballentine developed a new model, which showed that the "scar-forming" process of sequestering of incompatible elements from the rest of the mantle is occurring not just in the crust but independently in the deep mantle thanks to old oceanic plates that were drawn all the way down.

"Our work demonstrates that the processes determining the mantle's composition are more complicated than we previously thought," Tucker concluded.

Record-setting rain and heat? This is the new normal

I'm the director of the North Carolina Climate Office, which is the go-to source for expertise in North Carolina's climate. But if you call me to ask if there's a downpour on the way, I probably won't know the answer off the top of my head. That may seem odd, but it's because I'm mostly thinking about the climate—and weather is something a little different.
We  all have our favorite analogies for the difference between weather and climate. Weather—or the short-term events a place experiences—is equivalent to your mood. Climate—or average conditions over a longer time period—is your personality. Here in North Carolina, we know our climate is marked by mild winters and hot summers, with no distinct wet season. We can see days swing from 74°F on one day to 45°F the next.
However, that analogy about moods and personalities is somewhat imperfect in a rapidly changing world. With climate change, we're supercharging our atmosphere, like a baseball player on steroids. And even small shifts in our overall climate lead to huge changes in our extremes. As our personality shifts slightly, we see more of those bad mood days—and those moods can be worse than what we're used to.
We've seen some of those personality shifts in the past couple years.
2019 was officially North Carolina's warmest year in recorded history, per our neighbors in Asheville at NOAA's National Centers for Environmental Information (NCEI). We are seeing more daily maximum temperature records than minimum temperature records, while our nights have been warming significantly for the past few decades.
And it's not just the temperature here in North Carolina.
In 2018, North Carolina set an all-time state record for the most precipitation in a year at a single station. The official weather station at Mt. Mitchell—also the highest point east of the Mississippi—measured almost 12 feet of precipitation during the calendar year.
The location's 139.94" of precipitation was declared the new official record by NCEI in early July. It broke the previous record for Mt. Mitchell by more than three feet.
In other words, North Carolina is changing rapidly.
Climate change isn't just a polar bear floating on a lonely piece of ice. It's changing the conditions that are ideal for growing things like our prized sweet potatoes. It's threatening the health of our residents, and hurting the people who suffer the most—low-income communities who may not have sufficient access to cooling, or who live in flood prone areas. It's a .
We can point to the aftermath of Matthew, Florence, and Dorian. Flooding in Asheville. Longer, more intense  in Raleigh. Sunny day flooding in Wilmington. Coastal erosion on the Outer Banks. We no longer get the luxury of talking about  as a future problem. It's a now problem.
The bad news is that this is the new normal for only a short time. We will continue to warm. Our weather will continue to become more extreme. Those heat waves and floods from 2019 may seem insignificant in 2050.
North Carolina is among a few states that is actively preparing for a changing climate. Two recently-released reports—the North Carolina Climate Science Report and the North Carolina Risk and Resilience Plan—tackle pieces of our climate problem. We are looking at a different North Carolina in the coming decades. And we'll need a global strategy to ultimately change the trajectory that we're on if we ever want to get back to a "normal"  that is less extreme.

Red fox displaces Arctic fox thanks to littering

by Svein Inge Meland, Norwegian University of Science and Technology
The density of red foxes is increasing in Norway’s mountainous areas. The more trash and food waste red foxes have access to, the greater their numbers. This photo was taken with a game camera and shows a red fox that has found food. Credit: NINA, game camera

Animal species that are at home in the high mountains are finding their habitats reduced and fragmented by roads. In addition, they face competition from scavengers from lower boreal areas that find their way to the mountains.


"More cabins, more tourism and increased car traffic means more litter and more roadkill. For the red fox, the crow and other scavengers, it means more tempting food," says Lars Rød-Eriksen, who is employed as a researcher in terrestrial ecology at NINA, the Norwegian Institute for Nature Research.

In his doctoral work at NTNU, Rød-Eriksen surveyed road segments at Dovre, Saltfjellet and Hardangervidda to learn how wildlife is affected by the highways.

Roads = food

"We found that the red fox uses the road both to find food and to move from place to place. Especially in the winter, using the roadways is easier than traveling across the snowy terrain," he says.

"Using tracks in the snow and game cameras, we were able to document that the density of red foxes increases the closer to the road one gets. The more litter and food waste they have access to, the greater the number of red foxes that find their way to the area."

The researcher notes that the pattern is the opposite for Arctic foxes. "A lot of trash means few Arctic foxes. We found that the Arctic fox doesn't tend to stay close to the road. This is probably not because the they aren't attracted to the road, but because the presence of the red fox makes them keep their distance."

Weaker species displaced

Small rodents are the Arctic fox's specialty fare, but it isn't "too fussy" to eat trash. In competing with the red fox, however, it falls short.

"The Arctic fox is also attracted to roads, but the red fox is bigger and dominates in the competition between the species. There are also examples of red foxes that have killed Arctic foxes. Increased access to food enables the red fox to establish itself in the high alpine zone. The search for food is especially intense in late winter," Rød-Eriksen says.

The crow is both a competitor and a useful helper for the fox. Often crows are the first to discover a treat, but foxes are observant and use the crows to guide them to where the food is.


Unwelcome in the mountains

"The red fox has existed in the mountains before. But it's an invasive species and can disrupt the natural alpine ecosystem if it establishes itself there permanently, like it seems to be doing now. The Arctic fox is already an endangered species, and it seems likely that the red fox is impacting other alpine species as well, such as ptarmigan that are ground nesters. We call it a cascade effect when several species are affected," says Rød-Eriksen.


The graph shows that the number of red fox tracks per kilometre (y-axis) increases with the amount of edible waste (x-axis).

How about a litter law?

More roads and increased traffic also mean more roadkill. Rød-Eriksen believes it's easier to tackle the littering problem than the roadkill.

"Information campaigns can inform people about the consequences of throwing out and leaving trash and food scraps behind. A lot of people probably don't give any thought to how littering can negatively impact wildlife. Other countries have stricter legislation against littering. Maybe Norway should also consider it. Personally, I think it would be effective," says Rød-Eriksen.

Crow created research trouble

To record the movements of red foxes and Arctic foxes during the winter, Rød-Eriksen used tracking, supplemented by a game camera with bait at different distances from the road. These methods yielded good and reliable findings.

Summertime proved more difficult. The crows found the prey before the fox and often managed to eat it before the fox could get to it. Rød-Eriksen also placed artificial bird nests containing a real quail egg and a fake egg made from modeling clay along the transects.

The idea was that bite marks in the fake, soft egg would reveal whether a fox or a crow had tried to eat it. Here too, the crow created problems that made the results less reliable during the summer. Rød-Eriksen plans to take a closer look at seasonal variations and more comparable methods in future studies.

The movement of groundwater in aquifers deep beneath the surface often carries with it a variety of contaminants that can be traced to leaking septic systems, damaged underground infrastructure, excessive fertilizer use and other land uses. But where that groundwater and those contaminants end up is often unknown.
Using a drone with an infrared thermal imaging camera, a team of University of Rhode Island researchers led by doctoral student Kyle Young has tracked some of it to the Ocean State's coastal ponds.
"We're looking to quantify the amount of nutrients being brought into our estuaries and what's happening to those nutrients," said Young, a Coast Guard helicopter pilot and physics teacher at the Coast Guard Academy on leave to earn his doctorate. "The key nutrient is nitrate. In small amounts, nitrate is a good thing, but in larger amounts it can be degrading to the ecosystem."
Young and his advisor, URI Associate Professor Soni Pradhanang, seek to quantify the discharge of  into the  as part of an analysis of what they call a "" or an accounting of all of the water that flows into and out of the area.
"We know the amount of precipitation that comes down, we can quantify how much runoff goes into stream water, but one thing that's not easy to directly quantify is groundwater flow," said Pradhanang. "We don't know how much water is going from the aquifers into other water bodies."
Since the temperature of groundwater is cooler than the salt ponds in late summer, a drone equipped with an infrared thermal imaging camera can detect a plume of cool water in the ponds that is likely a discharge of groundwater. And that's exactly what Young and Pradhanang Lab graduate student Jeeban Panthi and undergraduate Janelle Kmetz have found at Green Hill and Ninigret ponds.
They flew their $10,000 drone at 400 feet over miles of salt pond coastline and captured several infrared images showing significant cool zones suggesting that groundwater is entering the pond from the bottom. Because groundwater is freshwater and less dense than the saltwater in the ponds, it rises to the surface, delivering a clear signal to the infrared camera.
"Just because we don't see plumes in some areas doesn't mean there isn't groundwater discharge there, too," noted Young. "There could be too small of a freshwater component for it to show up in the thermal signature, or it might not be cool enough compared to the surrounding water. But one thing we can say about the plumes we found is that they have ample freshwater, signifying waters that came from the terrestrial zone."
What that means for the health of the coastal ponds is uncertain. Discharges such as those the researchers found have likely been going on for many years, and groundwater doesn't always contain contaminants. But identifying their locations may be useful in tracking the movement of terrestrial pollutants into the ponds in the future.
The discovery also has implications in the context of climate change. According to Pradhanang, the groundwater affects the salinity and pH of the  water, which is critical to many water activities like aquaculture, as well as to the plants and animals that live in the ponds.
If storm surges happen more frequently, as is predicted with climate change, they might affect the amount of groundwater entering the water bodies, changing the environmental conditions and negatively affecting the wildlife that lives there. "It could have implications at an ecosystem level," Pradhanang said.
Now that the plume locations have been identified, Young is continuing his drone flights to see how the weather and tides affect the plumes.
"Flying highly sensitive equipment on an aircraft is high stakes research," he said. "Quantifying how the discharge changes over time is the next step. But so far it's nice that we've been able to identify the sites of possible pollution contribution to the ponds."
Once Young returns to the Coast Guard Academy next year, Pradhanang hopes future students will take up the project to identify groundwater discharge locations and quantities into other salt ponds, coastal and freshwater bodies, Narragansett Bay, and elsewhere around the region.

Pandemic accelerated remote work, a trend likely to remain

As with the previous pandemics and other major events, such as the Great Depression and World War II, the coronavirus pandemic will profoundly change workplaces and the nature of work itself.


In fact, it already has, according to a new article published by an international panel of management experts, including Michael Wilmot, a new assistant professor in the Sam M. Walton College of Business. Many of these changes, especially the massive shift toward remote work—what most people refer to as "working from home"—are probably here to stay.


"We know that previous major world events had a profound impact on workplaces and the kind of work people do," Wilmot said. "In fact, these events led to the demise of some markets and businesses and the creation of others. This pandemic is no different. It will change work in fundamental ways, and this will challenge people to learn to work in ways dramatically different than previous generations."
Wilmot, who studies the role of personality at work, was one of several researchers who contributed to "COVID-19 and the Workplace: Implications, Issues, and Insights for Future Research and Action," published in the August issue of American Psychologist. As the title suggests, the article emerged as an overview of previous research related to work and workplaces, studies that apply in the context of a pandemic. Lead authors—Kevin Kniffin at Cornell University, Jayanth Narayanan at the National University of Singapore, and Frederik Anseel at the University of New South Wales in Australia—describe the article as a generative overview, a framework for identifying work and workplace issues for producing future research.
The authors and contributors cited several previous studies pertinent to the context of the pandemic, especially those related to remote work, which communications technologies and faster internet connectivity have facilitated over the past several years. In this sense, COVID-19 merely accelerated an already growing trend. The authors pointed to a survey of 229 human resources departments showing that roughly half of the companies had more than 80% of their employees working from home during early stages of the pandemic. The companies expect substantial long-term increases for remote work after the .



The above trend, suddenly mandatory for almost all individuals who do their work from an internet-connected computer, creates or complicates a host of issues, including "presentism"—people working at home when ill—and the inability of some people to set boundaries between work and home.
As one who studies the role of personality at work, Wilmot contributed insights pertaining to disparate impacts on employees with regard to certain individual differences and personality traits. For example, how will these issues affect extroverts versus introverts?
The authors identified several other issues, including:
  • A loss of social connectedness and loneliness for many employees, which can negatively affect performance and commitment to organizational goals.
  • Increased risk among employees for substance abuse and addiction.
  • Related to above issues, companies might need to create or augment employee assistance programs and hire staff trained to recognize mental health issues.
  • The possibility that virtual work arrangements will foster more participatory relationships, given that physical cues of dominance are less salient in virtual environments.
  • The need for human resource departments to develop new performance management and appraisal systems for remote-working populations.
  • The expectation that some companies will institute new modes of surveillance due to perceived lack of control, now that employees are "out of sight."
"Considering all these issues and more, I think it's important to examine how workers will adapt," Wilmot said. "I'd like to think some of the insights we provide will make positive contributions in the face of these changes."

New feline vaccination guidelines

The American Animal Hospital Association (AAHA) and the American Association of Feline Practitioners (AAFP) convened a panel of experts to update the 2013 AAFP Feline Vaccination Advisory Panel Report. The release of the 2020 AAHA/AAFP Feline Vaccination Guidelines provides updated recommendations and the most current information for feline vaccinations.
The Task Force approached the update with evidence-based recommendations and peer-reviewed literature on feline vaccinations. "Working together with these two organizations affords our veterinary community exposure to the wisdom of colleagues who are dedicated to increasing the standard of care for cats," said Amy ES Stone, DVM, Ph.D., Chair of the 2020 AAHA/AAFP Feline Vaccination Guidelines Task Force.
The guidelines stress the need for an expanded understanding by veterinary professionals of individualized feline risk factors to determine a proper preventive healthcare plan. Practitioners are encouraged to gain better insight into feline patients' risk factors, which may include life stage, environment, and lifestyle.
Veterinarians should use these guidelines in conjunction with their own clinical experience and expert opinion, while considering the needs of the individual patient. "Cats used to be vaccinated for certain diseases based solely on whether they went outside or not. Those times have changed," said AAHA Senior Veterinary Officer Heather Loenser, DVM. "We need to tailor vaccine protocols for individual pets, rather than basing vaccination decisions on a single factor."
"We no longer can simply ask a client if the cat is 'indoors' or 'outdoors,'" said Kelly St. Denis, MSc, DVM, DABVP (Feline Practice), and 2020 AAFP President. "A client may not correctly interpret what they might consider brief or low-risk outdoor access, which may contain information that contributes to your risk assessment. We need to ask if the cat has  to outdoors; do they ever sit on a patio or in a cateo; do they have access to a balcony or open window; do they go anywhere outside of the home such as a friend's house or boarding facility; are they ever walked on a leash? A risk assessment of the other cats living in the home is also critical as these risks extend to all other cats in the house. By asking these questions you can better review the cat's risk for safety, nutrition, behavior, and zoonotic disease."
The guidelines provide resources for the entire veterinary practice team to utilize including:
  • A lifestyle-based feline vaccine calculator
  • FAQs and tips for client and staff education
  • Recommendations for core and noncore vaccines for pet and shelter-housed cats
  • A webinar summarizing the must-see and clinically important sections of the guidelines (available in October)
With these new guidelines, the team can educate pet owners about vaccination protocols and the overall importance to feline wellbeing, provide proper  recommendations for pet and shelter cats, and have open conversations to address clients' questions or concerns.AAFP releases updated Feline Zoonoses Guidelines

New bacteria and algae process could help decarbonize UK military

New bacteria and algae process could help decarbonise UK military
A new biological engineering process that could help to decarbonise the UK military is set to be developed by researchers at the University of Sheffield.
The cutting-edge research, led by academics in the University of Sheffield's Department of Chemical and Biological Engineering, is developing a novel bioprocess that uses a mixture of microbes to remediate waste.
The Ministry of Defense (MOD) generates large volumes of waste oils, fuels, lubricants and other liquid hydrocarbon waste each year. The University of Sheffield researchers will investigate how to break down complex hydrocarbon waste products using bacteria, turn them to  and then use algae to capture the CO2.
The team then plans to extract the  from the algal biomass and develop polymer chemistry methods for making biodegradable foams. These foams can be used in a variety of ways, including as synthetic soils to grow nutritional plants in water scarce environments.
This new research offers the opportunity to protect the environment, save money for the Ministry of Defense and the taxpayer, while allowing the MOD to manage and reduce its own waste.
The team not only aims to recover  but also make new by-products, while minimizing CO2 emissions.
Dr. Jagroop Pandhal, from the University of Sheffield's Department of Chemical and Biological Engineering, said: "The MOD has got a mixture of different types of hydrocarbon waste. We want to effectively break these down into simple components which are less harmful to the environment, and then build them up again into useful resources. These steps will be undertaken by selected microbial strains working together as a team. What we want to do is resource recovery, so it's not just about cleaning up the waste, it's trying to get resources out of it."
Although there are many applications for converting algae into useful products, here researchers will investigate conversion of the oils into  with , replacing unsustainable sources currently used.
Dr. Pandhal said: "Algae are able to absorb CO2 for growth, similar to any other plant, and therefore are able to capture this gas when it's released during bacterial degradation of the hydrocarbon waste. And it's this algal biomass that provides a treasure trove of bio-based products."
As well as being used in , it is intended the technology can be further developed into portable bioprocessing systems for overseas bases and operational deployments.
