Ames, IA — Twenty years ago, the National Football League adopted the Rooney Rule. It attempted to address racial disparity in top positions by requiring teams to interview at least one person of color for every head coach opening. But newly published research suggests the gap will persist unless it’s closed at the bottom. The NFL has a hierarchal labor pool, explains Andreas Schwab, co-author and associate professor of entrepreneurship at Iowa State University. Under the head coach are two coordinators who oversee defense and offense. These coordinators supervise position-specific coaches who may have their own assistant coaches. “To become ...

FROM: James Urton University of Washington 206-543-2580 jurton@uw.edu  (Note: researcher contact information at the end)   For Immediate Release August 21, 2023   In 2006, the Tripod Complex Fire burned more than 175,000 acres in north-central Washington. The fire, which was within the Okanogan-Wenatchee National Forest, was more than three times the size of Seattle. Yet while considered severe at the time, even larger wildfires in 2014, 2015 and 2021 have since dwarfed Tripod. Past research shows that large and severe wildfires like these were much rarer in the western U.S. and Canada prior to the late ...

AMES, Iowa – Yan Zhao gestured toward the trees outside his campus window on a rainy afternoon.   The professor of chemistry at Iowa State University is developing new synthetic catalysts to break down cellulose, the plant fibers that make those trees tall and strong.   “Cellulose is built to last – a tree doesn’t just disappear after rain,” Zhao said. “Cellulose is a huge challenge to break down.”   Zhao thinks he has an idea and a technology that can get the job done, making plant biomass a practical source of sugars that can be converted to many applications, including ...

Nearly one million people in the United States are living with Parkinson’s disease, making it the second-most common neurodegenerative disease after Alzheimer’s. Current medical treatments for Parkinson’s are focused on helping people manage symptoms. But the underlying mechanisms of the neurological disorder remain poorly understood.  Tamily Weissman, associate professor of biology and department chair, is working to change that. Parkinson’s symptoms occur because of a drop in dopamine levels when ...

A study of 14 astronauts suggests that while space travel depletes red blood cells and bone, the body can eventually replenish them back on Earth with the help of fat stored in the bone marrow. The study, published in Nature Communications, has important implications for health in space and on Earth. “We found that astronauts had significantly less fat in their bone marrow about a month after returning to Earth,” said senior study author Dr. Guy Trudel, a rehabilitation physician and researcher at The Ottawa Hospital and professor at the University of Ottawa. ...

Research Highlights: An analysis of more than 45,000 people infected with SARS-CoV-2 found a significant association between the virus and the development of persistent high blood pressure among those with no prior history of high blood pressure. In addition, people with COVID-19 infection and no history of high blood pressure were significantly more likely to develop persistent high blood pressure compared to people with the influenza virus. People with COVID-19 who are over age 40, men, Black adults or those with preexisting ...

ANN ARBOR, Mich. –  As children head back to school, two issues have climbed higher on their parents’ list of concerns: the role of social media and the internet in kids’ lives. Over half of parents also rate mental health issues as leading health concerns for children and teens, according to the University of Michigan Health C.S. Mott Children’s Hospital National Poll on Children’s Health. Overall, emotional health and technology use dominated this year’s top 10 list of parent concerns about health-related issues for kids in the U.S.– surpassing childhood obesity, which parents rated the number one children’s health issue ...

The Big Wasp Survey, a citizen science project involving thousands of volunteers throughout the UK, has yielded important genetic insights into the common wasp, reports a study led by UCL researchers. Using data and samples of Vespula vulgaris (a species of yellowjacket wasp known as the Common Wasp) collected by amateur ‘citizen scientists’, the researchers conducted the first large-scale genetic analysis of the insect across its native range. The insights, published in Insect Molecular Biology, revealed a single population of the wasp across Britain, while the insect’s genetics were more differentiated across the Irish Sea in Northern Ireland. The researchers ...

Multiple studies have demonstrated the memory-enhancing effects of melatonin and its derivatives in animal models. It is also known that the formation of both short- and long-term memories require the phosphorylation of certain memory-related proteins. However, the molecular mechanisms underlying melatonin-induced memory enhancement have remained elusive. Now, medical researchers from Sophia University, Japan, have made important findings that contribute significantly to the elucidation of the underlying mechanisms in a recent article that was made available online on 10 May 2023 and published in Volume 34 Issue 9 of NeuroReport on 7 June 2023. Regarding the premise of the study, ...

As a manned spacecraft operating in orbit for a long time, a space station embodies a country’s scientific and technological strength comprehensively. China’s manned space project was approved in 1992 with a 3-step strategic plan, and building a space station is the final goal of this plan. In September 2010, China’s manned space station project was officially established. After 11 years of unremitting efforts, on 2021 April 29, the Tianhe core module was successfully launched into orbit by the carrier rocket ...

Research at a Glance: A Murdoch Children’s Research Institute-led review has found COVID-19 vaccines are effective against severe cases of the disease in children and adolescents. However, with most children now having caught the SARS-CoV-2 virus and building up a natural immunity, the additional benefit of vaccination in healthy children is minimal The review explored the challenges and considerations around COVID-19 vaccination of children, especially in low- and middle-income countries, in the context of high levels of community transmission and infection-derived ...

Ecosystem services (ESs) provide a variety of services and benefits for human well-being, but the supply-demand mechanism of ecosystem services under different spatio-temporal scales is unclear. The Taihu Lake Basin (TLB) is a microcosm of degraded and unsustainable ecosystem services. Rapid industrialization and urbanization poses a great threat to the environment and ecology. Therefore, it is urgent to assess the changes in supply and demand for TLB ecosystem services from a spatio-temporal and multi-stakeholder perspective, and ...

Medical students who reported a disability to their school increased by more than 25% during the COVID-19 pandemic, a study shows. The proportion of students reporting attention deficit hyperactivity disorder or chronic health and/or psychological disabilities has increased between 2015 and 2021. Despite the increase in medical students reporting these conditions, the requests for more inclusive preclinical testing accommodations, like extra time for test completion or a less distracting environment, decreased during the pandemic between 2019 and 2021. According to authors of the new research letter in JAMA Network Open, the remote curriculum delivery during the pandemic may have allowed ...

The U.S. Department of Energy has awarded an LSU-led consortium a $4.9 million grant to support the first phase of the Pelican Gulf Coast Carbon Removal project. The Pelican Consortium, which includes Shell and the University of Houston, will evaluate the feasibility of building a direct air capture (DAC) hub in Louisiana. DAC technologies capture carbon dioxide directly from the atmosphere. The captured carbon dioxide can then be used to manufacture products or be permanently stored in deep geological formations. The project will leverage existing regional infrastructure in one of the highest emitting areas in the Gulf Coast, benefit the local energy workforce, and support ...

E-cigarettes do have value as a smoking cessation aid, according to a new study just released by a team of MUSC Hollings Cancer Center researchers.   Whether e-cigarettes should be considered for smoking cessation is a hotly debated topic, and different countries have taken different approaches. E-cigarettes contain harmful chemicals, which has led many public health advocates to shun them. But they are less harmful than traditional cigarettes, which can cause a dozen types of cancer as well as heart disease, stroke, diabetes and chronic obstructive ...

LA JOLLA, CA—According to new research in the journal Immunity, T cells have a nuclear receptor doing something very odd—but very important—to help them fight pathogens and destroy cancer cells. This receptor, called retinoic acid receptor alpha (RARα), is known to control gene expression programs in the nucleus, but it also now appears to operate outside the cell nucleus to coordinate the early events triggered at the cell surface that lead to T cell activation. Scientists wouldn’t normally expect to see a nuclear receptor ...

Organisms across the globe are facing unprecedented levels of stress from climate change, habitat destruction, and many other human-driven changes to the environment. Predicting and mitigating the effects of this increasing stress on organisms, and the environmental services on which we depend, requires understanding why some species can exist in a wide range of environments while others exist in only a few habitats. In the scientific world of ecology, researchers often try to sort organisms on our planet into two categories: specialists and generalists. Generalists can survive across a wide variety of environmental conditions and habitats, while specialists ...
