Experts in fire ecology will converge at the Ecological Society of America’s upcoming Annual Meeting in Long Beach, Calif., Aug. 4–9, presenting the latest research on the causes and consequences of wildland fire in dozens of talks and posters. The growing threat of wildfire makes understanding the past, present and future of fire regimes essential. Fire ecology addresses crucial questions such as how different species and ecosystems respond to burns, which habitats are most vulnerable and how forests recover—or fail to recover—after ...

CORVALLIS, Ore. – A newly enhanced database is expected to help wildfire managers and scientists better predict where and when wildfires may occur by incorporating hundreds of additional factors that impact the ignition and spread of fire. “There is a tremendous amount of interest in what enables wildfire ignitions and what can be done to prevent them,” said Erica Fleishman, an Oregon State University professor. “This database increases the ability to access relevant information and contribute to wildfire ...

HERSHEY, Pa. — A team of researchers from Penn State College of Medicine found a new target for treating diseases associated with human T-cell leukemia virus type 1 (HTLV-1).  They determined that blocking a class of enzymes called kinases, which regulates cellular functions, leads to cell death caused by the degradation of Tax, a protein essential for viral gene expression, viral transmission and survival of cells infected by HTLV-1. The team published the findings in Nature Communications. HTLV-1 is a retrovirus — a type of virus that hijacks a cell by inserting ...

Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of supermassive black holes (SMBHs) can merge into a single larger black hole because of previously overlooked behaviour of dark matter particles, proposing a solution to the longstanding “final parsec problem” in astronomy. The research is described in Self-interacting dark matter solves the final parsec problem of supermassive black hole mergers published this month in the journal Physical Review Letters.  In ...

A migraine is not just a bad headache. It is a much-dreaded part of a neurologic disorder that has an array of possible symptoms, including pulsating cranial pain, waves of queasiness, bouts of vomiting, and hypersensitivity to light and sound. They frequently materialize unannounced and at the most inopportune of moments. Pubescent girls with a family history of migraine headaches are especially vulnerable — yet there remain many unknowns regarding the who, when and why of the disorder. Hadas Nahman-Averbuch, PhD, a scientist at Washington University School of Medicine in St. Louis with expertise ...

(Santa Barbara, Calif.) — The field of science aims to be objective, repeatable and justified in its choices and methods. These principles are what distinguish accepted scientific findings from pseudo-science. Yet the experience of learning and working in the field of science, including graduate school activities and scientific conferences, might not always follow the same principles. These practices and gatherings of scientists may be just as organic and random as evolution. Have the traditions of science — rituals of poster presentations and tenure positions — evolved by chance? ...

PROVIDENCE, R.I. [Brown University] — Brown University biologists who set out to better understand the effects of climate change on plant species in tropical mountain regions found that even small variations in temperature and moisture can have massive impacts, threatening not only plants that live there, but also the ecosystems they support. Emily Hollenbeck, who conducted the research while earning her Ph.D. in ecology and evolutionary biology from Brown, made the discoveries through a series of laborious yet informative experiments conducted in the Monteverde mountain ...

Research led by Curtin University reveals that Earth’s largest iron ore deposits – in the Hamersley Province of Western Australia – are about one billion years younger than previously believed, a discovery which could greatly boost the search for more of the resource. Using a new geochronology technique to accurately measure the age of iron oxide minerals, researchers found the Hamersley deposits formed between 1.4 and 1.1 billion years ago, rather than 2.2 billion years ago as previously estimated. Lead author Dr Liam Courtney-Davies, who was a Postdoctoral Research Associate at Curtin University’s John de Laeter ...

How did the 2021 national marriage equality referendum campaign in Switzerland affect the well-being of the LGBTIQ+ community? A team led by researchers at UZH has shown that LGBTIQ+ individuals and their cisgender heterosexual allies exhibited more stress hormones during the controversial campaign. Lesbian, gay, bisexual, trans, intersex and queer (LGBTIQ+) individuals face persistent structural inequalities and discrimination that can adversely affect their well-being. When concerns of the LGBTIQ+ community are discussed in widespread public debates, such as during political initiative and referendum campaigns, that can ...

Interest in Earth-like planets orbiting within the habitable zone of their host stars has surged, driven by the quest to discover life beyond our solar system. But the habitability of such planets, known as exoplanets, is influenced by more than just their distance from the star. A new study by Rice University’s David Alexander and Anthony Atkinson extends the definition of a habitable zone for planets to include their star’s magnetic field. This factor, well studied in our solar system, can have significant implications for life on other planets, according ...

In the past few years, we’ve seen a push toward renewable energy. One focus is wind, which is harvested via turbines–you may have seen them in mountainous areas, turning in the wind. But the United States’s most abundant wind potential lies offshore; wind speeds are highest off both coasts. This means offshore wind turbines promise high energy yields, akin to the offshore wind production in the North Sea near northern Europe. But constructing wind turbine platforms in water deeper than ~60 meters presents problems. Turbines in shallow waters, like those in the North Sea, can be mounted on fixed-bottom platforms, held ...

COLORADO SPRINGS, Colo. — There is a potential connection between a diagnosis of certain gastrointestinal (GI) syndromes and the formation and rupture of intracranial (brain) aneurysms, according to research presented today at the Society of NeuroInterventional Surgery’s (SNIS) 21st Annual Meeting.   An intracranial aneurysm (IA) occurs when a blood vessel in the brain bulges, putting pressure on the vessel wall. IAs that rupture cause brain bleeding and lead to a hemorrhagic stroke, a life-threatening emergency requiring immediate medical attention ...

Everyone knows that air pollution is bad for health, but how bad depends a lot on who you are. People of different races and ethnicities, education levels, locations and socioeconomic situations tend to be exposed to different degrees of air pollution. Even at the same exposure levels, people’s ability to cope with its effects — by accessing timely health care, for example — varies. A new study by Stanford Medicine researchers and collaborators, which takes into account both exposure to air pollution and susceptibility to its harms, found that Black Americans are significantly more likely to die from causes related to air pollution, compared ...

CHAMPAIGN, Ill. — During a checkup with her obstetrician, Marilyn Hayes tells him about overwhelming exhaustion and possible symptoms of postpartum depression, such as feeling unsafe. Hayes, a Black woman, grows increasingly frustrated as her white, male physician, Dr. Richard Flynn, dismisses her symptoms and ignores her wishes when she refuses medication. Hayes becomes visibly uncomfortable when Flynn touches her without permission and makes comments steeped in Black stereotypes, such as assuming that ...

A new study finds that science and social studies classes may also help young students learn English, even when those classes include difficult and technical vocabulary. The study, which observed first- and second-grade students in 30 elementary schools in North Carolina, encouraged teachers to keep their English-learning students in class during science and social studies lessons. Science and social studies textbooks in those grades are often relatively technical and difficult for students, so traditional teaching methods in North Carolina encourage teachers to remove English-learning students from those content classes ...
