With an extendable pole fitted with a small camera, Alison Ke could get a clear view of the inside of a nest box, including one time when a small, green Pacific parrotlet laid eggs. Ke, who earned a Ph.D. in ecology from UC Davis, led a research project to find out how converting rainforest to farmland affects the habitat of birds who rely on tree holes, or cavities, for nesting. Ke worked closely with local scientists and community members to study birds around the Mache-Chindul Ecological Reserve, an area in northwest Ecuador that has experienced rapid deforestation and agricultural expansion in the past 50 years. Their study, ...

Between 30 to 50 percent of people living with multiple sclerosis (MS) will experience memory problems but the cause is uncertain. Brain lesions are the hallmark imaging sign used to diagnose MS and are often associated with memory dysfunction. However, increased MS brain lesions are not specific to memory problems and are also associated with fatigue, walking difficulty and other common MS symptoms. Previous studies that attempted to align the anatomy of lesions associated with memory problems in MS led to conflicting ...

ROCHESTER, Minn. — Getting a COVID-19 vaccine may not only reduce a person's risk of getting long-haul COVID, but also could mean fewer symptoms for people who develop the condition. Mayo Clinic researchers discovered that long-haul COVID patients who were vaccinated before contracting the virus were less likely to experience symptoms such as abdominal pain, chest pain, dizziness, and shortness of breath, according to a study published in the Journal of Investigative Medicine. The study is believed to be among the first to examine COVID-19 vaccines' potential to reduce ...

MSU research suggests natural selection can slow evolution, maintain similarities across generations Highlights: New research from Michigan State University suggests that natural selection, famous for rewarding advantageous differences in organisms, can also preserve similarities. Reporting in the journals New Phytologist and Evolution, the researchers worked with a plant called wild radish and its stamens, or pollen-producing parts, two of which are short and four are long. Roughly 55 million years ago, wild radish ancestors had stamens of equal length. The team selectively bred — or artificially selected — ...

ITHACA, N.Y. - To prepare for extreme heat waves around the world – particularly in places known for cool summers – climate-simulation models that include a new computing concept may save tens of thousands of lives. The concept, called “ensemble boosting,” uses computationally efficient modeling to simulate a large set of extreme but plausible heat waves, all while avoiding hundreds of hours of expensive calculations on large computers. The study on the new modeling method, led by scientists at ETH Zurich, Switzerland and Cornell University, was published Aug. ...

In the wake of the 2022 Supreme Court ruling in Dobbs v. Jackson Women's Health Organization that overturned Roe v. Wade, researchers at the University of Chicago set out to investigate whether anticipation of restricted abortion access increased interest in vasectomies in the preceding years. In a new analysis, they found that vasectomy rates in the United States witnessed a remarkable surge from 2014 to 2021, as more men opted for the outpatient surgical procedure that offers permanent contraception by preventing ...

Almost everything about insects called kissing bugs is revolting, from the insidious way they bite people’s faces at night to drink their blood while they sleep to the way they spread disease through their poop. Some carry a parasite called Trypanosoma cruzi that causes Chagas disease, a leading cause of disability and premature death in the Americas. Left untreated, Chagas disease can cause serious heart and digestive problems. It’s showing up more and more in patients in the United States. Now researchers at the University of Cincinnati are investigating ...

DURHAM, N.C. -- New research finds brands that leverage a reputation for quality to pay employees less risk eroding profits. The paper, published online June 12 in the Journal of Marketing Research and authored by researchers from Duke University, London Business School and Texas A&M University, shows that vertical brand differentiation (being perceived as better) is associated with lower pay, whereas horizontal brand differentiation (being perceived as different) is associated with higher pay. High-quality brands taking advantage of brand cachet to pay employees less erodes profits due to negative effects on employee productivity ...

A caregiver’s education level and their child’s age played large roles in determining their primary sources of stress during the COVID-19 pandemic, researchers found in a recent study by NIH’s Environmental influences on Child Health Outcomes (ECHO) Program. Caregivers who had less than a high school education were less likely to work remotely and were more worried about finances, childcare, and access to necessities like food. Caregivers with a master’s degree or higher reported greater concern about social distancing and impacts on their work. The ...

A study by health policy researchers at Columbia University Mailman School of Public Health and University of Southern California projects that the expected health and economic well-being of Americans nearing retirement age in the lower half of the economic distribution today is no better than that of their counterparts more than two decades ago. The focus of most policy efforts has been to support the most disadvantaged, generally considered the lowest 15 percent of the population with respect to financial resources. Less attention has been drawn to those between the 15th and ...

Lower-middle class Americans nearing retirement age are worse off than their counterparts more than two decades ago, while upper-middle Americans have largely seen their life expectancy and wealth improve. Policymakers, meanwhile, overlook the lower middle group of Americans who don’t qualify for many assistance programs. That’s according to a new study by the USC Schaeffer Center for Health Policy & Economics and the Columbia University Mailman School of Public Health. Using data from the Health and Retirement Survey and a microsimulation called the Future Elderly Model, researchers estimated future life expectancy and disability for cohorts of individuals ...

EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, AUGUST 23, 2023 MINNEAPOLIS – Millions of Americans were exposed to SARS-CoV-2, the virus that causes COVID-19, early in the pandemic but could not get diagnosed due to testing limitations. Many of those people developed a post-viral syndrome with symptoms similar to those of long COVID.  In a new study of a small group of those people, their immune response shows that 41% had evidence of SARS-CoV-2 exposure. The study is published in the August 23, 2023, online issue of Neurology® Neuroimmunology & Neuroinflammation, an official journal of the American Academy of Neurology. Long COVID was defined as symptoms persisting ...

An international phase 3 clinical trial, done in participation with Weill Cornell Medicine and NewYork-Presbyterian, found that a new targeted treatment called zolbetuximab, given in combination with a standard chemotherapy, extended survival for patients with advanced gastric or gastroesophageal junction cancer that overexpressed a specific biomarker. Results from the GLOW study, published July 31 in Nature Medicine, together with results from the parallel SPOTLIGHT study that evaluated zolbetuximab with an alternative standard chemotherapy, prompted the ...

Exposure to night shift work and rotating shift work is associated with an increased risk of cognitive impairment among middle-aged and older adults, according to a new study published this week in the open-access journal PLOS ONE by Durdana Khan of York University, Canada, and colleagues. Previous research has established that shift work, which refers to any work schedule that occurs outside the traditional 9am to 5pm working hours, has significant health impacts. In the new work, the researchers analyzed data on 47,811 adults in the Canadian Longitudinal Study. The dataset included ...

Sperm and northern bottlenose whales were frequently observed following a trawler off the coast of Newfoundland to feed on fish escaping from the net as it was hauled in, according to a study published August 23, 2023 in the open-access journal PLOS ONE by Usua Oyarbide from Plentzia Marine Station–Univ Basque Country, Spain, and colleagues. In this study, the authors looked at how cetaceans interacted with a deep-sea trawler fishing in the western North Atlantic off the coast of Newfoundland in 2007. Oyarbide tracked whale encounters over 50 days between July 20 and September 13, 2007, while onboard the trawler as a North Atlantic Fisheries Organization observer. Sperm whales (Physeter ...

Researchers from Queen Mary University of London have made a discovery that could change our understanding of the universe. In their study published in Science Advances, they reveal, for the first time, that there is a range in which fundamental constants can vary, allowing for the viscosity needed for life processes to occur within and between living cells. This is an important piece of the puzzle in determining where these constants come from and how they impact life as we know it.  In 2020, the same team found that the viscosity of liquids is determined by fundamental physical constants, setting a limit on how runny a ...

Nerve cells that sense touch grow the appropriate endings for hairy or hairless skin based on cues from the skin itself, rather than through predetermined programming, according to research led by Harvard Medical School scientists and published Aug. 21 in Developmental Cell.  If affirmed in further studies, the findings could eventually help researchers develop therapies to regenerate damaged or diseased nerves, the authors say, or better understand what goes awry in congenital neuropathies, conditions in individuals born with ...

Amsterdam, August 23, 2023 – While myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and Long COVID are not the same disease, they appear to have features of overlapping biological and symptomatic presentations.
