It’s that time of year again. The days are getting shorter, and the nights are cooling down. But when will the natural fireworks display of autumn leaves actually begin this year?Many people believe that climate change is pushing back the start of fall leaf color to later in the year. The general thinking is that the warmer conditions anticipated under climate change will mean that trees can “hang on” to their green, energy-producing leaves longer.
Melatonin use among children and teenagers is on the rise. Today, the American Academy of Sleep Medicine released a health advisory encouraging parents to talk to a health care professional before giving melatonin or any supplement to children.
As people with HIV age, their risk of heart attack increases far more if they also have untreated hepatitis C virus, even if their HIV is treated, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.
Mount Sinai study also shows catching up on sleep doesn’t reverse possible negative effects on cellular level
Webb's first look at Neptune is certainly a stunner! We're getting the clearest view of Neptune's rings in decades. The faint, dustier bands have never been seen in the infrared like we see now. At near-infrared wavelengths, Neptune's methane gas so strongly absorbs red and infrared light that the planet is quite dark, except where high-altitude clouds are present. These methane-ice clouds are prominent as bright streaks and spots in Webb's view.
The woodpecker forebrain contains specialized pecking-related regions that resemble those associated with song and language systems.

A study assessed resident physicians’ perceptions, coping strategies and self-reported levels of depression, anxiety and stress experienced during the early phase of the pandemic. Results showed that 88.1 percent felt they were likely or very likely to become infected with COVID-19. If infected, 28.8 percent felt that their illness would be serious or very serious. With respect to depression, anxiety and stress, all the mean scores were in the normal range. For depression, residents in emergency medicine and surgery reported higher levels. The top three coping strategies included acceptance, self-distraction, and use of emotional support. The three least used strategies included behavioral disengagement, substance use and denial.
Managers know that happy employees are more productive and provide better customer service, but what is the cost of that service with a smile? New research from the Terry College of Business reveals becoming a happy, helpful employee takes effort and, eventually, that effort erodes the energy needed to do one’s job. It could lead to quiet quitting – the new term for just doing your job but not going above and beyond – or even actual quitting.
To simulate stellar novae accurately on computers, researchers need accurate inputs for nuclear reaction rates. Nuclear physicists have now determined an important and challenging proton-capture reaction rate using laboratory experiments. A state-of-the-art nova simulation incorporates the new experimental information, allowing physicists to compare the results for comparison to actual nova observations.

Researchers in the laboratory of Yulia Nefedova, M.D., Ph.D., at The Wistar Institute and collaborators at Jubilant Therapeutics Inc. have uncovered a novel mechanism by which protein arginine deiminase 4 (PAD4) in neutrophils promotes cancer progression. The paper also found that inhibition of this function of PAD4 reduces primary tumor growth and metastasis and enhances checkpoint inhibitor treatments.
A new study led by scientists at Woods Hole Oceanographic Institution (WHOI) and University of Washington Applied Physics Laboratory (UW APL) finds that marine predators, such as tunas, billfishes and sharks, aggregate in anticyclonic, clockwise-rotating ocean eddies (mobile, coherent bodies of water). As these anticyclonic eddies move throughout the open ocean, the study suggests that the predators are also moving with them, foraging on the high deep-ocean biomass contained within.
Despite the high number, first global assessment shows illegal exploitation slightly declining.
1 in 5 adult female white-necked jacobin hummingbirds look like males. New research from the University of Washington shows that this is a rare case of "deceptive mimicry" within a species: Females with male-like plumage are trying to pass themselves off as males, and receive a benefit in the form of reduced aggression.
NASA’s James Webb Space Telescope presents a new perspective on 30 Doradus, or the Tarantula Nebula, a region well-known to astronomers studying star formation. Its nickname once came from its resemblance to the spider itself, but in Webb’s view the overall region takes on the appearance of a tarantula’s home—a burrow lined with its own spun silk. The Tarantula Nebula shelters thousands of young and still-forming stars, many revealed by Webb for the first time.
Irvine, Calif., Sept. 1, 2022 – Anxiety, autism, schizophrenia and Tourette syndrome each have their own distinguishing characteristics, but one factor bridging these and most other mental disorders is circadian rhythm disruption, according to a team of neuroscience, pharmaceutical sciences and computer science researchers at the University of California, Irvine.
