No, autumn leaves are not changing color later because of climate change
Washington University in St. Louis

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.

New Webb Image Captures Clearest View of Neptune's Rings in Decades
Space Telescope Science Institute (STScI)

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.

Anti-sedative could alleviate cancer therapy side effects, study suggests
The Rockefeller University Press

Researchers in China have discovered that inhibiting a protein called the GABAA receptor can protect intestinal stem cells from the toxic effects of chemotherapy and radiotherapy. The study, published September 20 in the Journal of Experimental Medicine (JEM), suggests that the FDA-approved anti-sedative flumazenil, which targets GABAA receptors, could alleviate some of the common gastrointestinal side effects, such as diarrhea and vomiting, induced by many cancer treatments.

FAU Resident Physicians Report COVID-19 Impacts
Florida Atlantic University

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.

‘Service with a smile’ costs more than you think
University of Georgia

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.

How marine predators find food hot spots in open ocean “deserts”
Woods Hole Oceanographic Institution

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.

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.
