There are many lingering mysteries from the COVID-19 pandemic. For instance, why does SARS-CoV-2, the virus behind the disease, cause severe symptoms in some patients, while many other coronaviruses don’t? And what causes strange symptoms to persist even after the infection has been cleared from a person’s system?   The world may now have the beginning of answers. In a study published today in the journal Proceedings of the National Academy of Sciences, a UCLA-led multidisciplinary research team explores one way that COVID-19 turns the ...

New research finds that individual behavioural flexibility and not evolutionary selection is driving the northward shift of Balearic shearwaters. The findings were revealed through a decade-long study which tagged individual birds. The results indicate that individual animals may have greater behavioural flexibility to respond to climate change impacts than previously thought. How individual animals respond to climate change is key to whether populations will persist or go extinct. Many species are shifting their ranges as the environment warms, but up to now the mechanisms underlying ...

Scientists have found that the spatial arrangement of plants in drylands can be a sign of the environment degrading, according to a new study. One of the iconic features of drylands is the striking appearance of islands of plants surrounded by bare soil. This spatial structure of arid vegetation has long fascinated scientists, but now a new study published in Proceedings of the National Academy of Sciences, has shed new light on why these plants group in this way. An international team of scientists, including from the University of Birmingham, combined field data from 115 sites around the world, and used mathematical models and remote sensing to build a picture of how the ...

A startling number of people conceal an infectious illness to avoid missing work, travel, or social events, new research at the University of Michigan suggests. The findings are reported in Psychological Science, a journal of the Association for Psychological Science. Across a series of studies involving healthy and sick adults, 75% of the 4,110 participants said they had either hidden an infectious illness from others at least once or might do so in the future. Many participants reported boarding planes, going on dates, and engaging in other social interactions while secretly sick. More than 61% of healthcare workers participating in the study also ...

New material is self-assembling, long-lasting and recyclable. As electronic devices get smaller, the materials needed to create them get smaller as well. Nanoscience is the study of extremely small materials that find uses in energy storage, electronics, health and safety applications and more. Now a team led by the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory has developed a new self-assembly method to fabricate multilayered 2D nanosheets. A nanosheet is an extremely small, lasagna-like material made of ultrathin layers of polymers and nanoparticles. These nanosheets have significantly ...

Researchers at OU Health Stephenson Cancer Center at the University of Oklahoma Health Sciences have embarked on a revolutionary new research study that could improve the detection of a deadly disease — pancreatic cancer — and give patients a chance to live longer, healthier lives. The research focuses on an innovative combination of imaging techniques: a newly created contrast agent that recognizes pancreatic cancer cells, paired with Multispectral Optoacoustic Tomography, or MSOT. Together, the approach can detect pancreatic cancer cells the width of an eyelash ...

As sea levels rise due to global warming, ecosystems are being altered. One small silver lining, scientists believed, was that the tidal wetlands found in estuaries might produce less methane – a potent greenhouse gas – as the increasing influx of seawater makes these habitats less hospitable to methane-producing microbes.   However, research from biologists at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley indicates that these assumptions aren’t always true. After examining the microbial, chemical, and geological features of 11 wetland zones, the team found that a wetland region exposed ...

A new qualitative study highlights the negative interpersonal and psychological consequences associated with “yo-yo dieting,” also known as weight cycling. The work underscores how toxic yo-yo dieting can be and how difficult it can be for people to break the cycle. “Yo-yo dieting – unintentionally gaining weight and dieting to lose weight only to gain it back and restart the cycle – is a prevalent part of American culture, with fad diets and lose-weight-quick plans or drugs normalized as people pursue beauty ...

Star-shredding black holes are everywhere in the sky if you just know how to look for them. That’s one message from a new study by MIT scientists, appearing today in the Astrophysical Journal.  The study’s authors are reporting the discovery of 18 new tidal disruption events (TDEs) — extreme instances when a nearby star is tidally drawn into a black hole and ripped to shreds. As the black hole feasts, it gives off an enormous burst of energy across the electromagnetic spectrum.  Astronomers have detected previous tidal disruption events by looking for characteristic bursts in the optical and X-ray bands. To date, these searches have ...

January is a time when many people are looking for new diet routines, and intermittent fasting is trending, as are traditional calorie cutting programs. Research conducted with animal models suggests that intermittent fasting slows aging, and those animals live longer. Researchers at the Pennington Biomedical Research Center and the University of Alabama at Birmingham are conducting the DiAL-Health study to see if eating for 8 hours and fasting for 16 each day shows similar results in people. These researchers ...

Like it or not, social media has become the new mall for kids. It’s where they want to be, and it’s a place they can easily go—often with no guidance, no oversight, and no guardrails. And when the content gets ugly or confusing or weird, it can be tough for them to know what to do. Dominic DiFranzo, an assistant professor of computer science and engineering in Lehigh University’s P.C. Rossin College of Engineering and Applied Science, has devoted his research to helping kids better navigate the perils of social media. He and his team have recently received two grants from the National Science Foundation to develop artificial intelligence tools ...

'Millennials don't really want to work. They're far too focused on avocado toast and chai lattes!' Just one of the many clichés expressed by workers over the age of fifty. And those being criticized? Well, they often reply with a bored 'OK, Boomer' followed by an eye roll and some ironic remark about the excessively performance-driven worldview of those born between the mid 1950s and the mid 1960s. Work, it seems, just isn't as important to the young as it is to older generations. But it's not just about baby boomers and millennials. Parked between them is Generation X, ...

Calcium ions are essential for cells, but can be toxic in higher concentrations. A team of researchers has now designed and prepared a combination drug that kills tumor cells by modulating the calcium influx into the cell. An external calcium source is not necessary because only the calcium ions already present in the tumor tissue are used, according to the study published in the journal Angewandte Chemie. Biological cells need calcium ions, among other things, for the proper functioning of the mitochondria, the powerhouses of the cells. However, ...

A University of Houston optometry researcher is warning against the use of low-level red light (LLRL) therapy as a method to control myopia, or nearsightedness, especially in children. Over the last few years, LLRL has emerged as a viable myopia treatment after studies reported the treatment as effective and responsible for significant reduction in myopia progression. The company behind one of the devices reports that it is already being used to address myopia in over 100,000 pediatric patients.   But the excitement over its results as a myopia treatment may have come too soon, ahead of its proven safety.  "Based on measurements in our laboratory, ...

Humans and our closest relatives, living apes, display a remarkable diversity of types of locomotion—from walking upright on two legs to climbing in trees and walking using all four limbs.  While scientists have long been intrigued by the question of how humans’ bipedal stance and movement evolved from a quadrupedal ancestor, neither past studies nor fossil records have permitted the reconstruction of a clear and definitive history of the early evolutionary stages that led to human bipedalism. However, a new study, which centers on recently discovered evidence from skulls of a 6-million-year-old fossil ape, Lufengpithecus, ...

Five cases of Alzheimer’s disease are believed to have arisen as a result of medical treatments decades earlier, reports a team of UCL and UCLH researchers. Alzheimer’s disease is caused by the amyloid-beta protein, and is usually a sporadic condition of late adult life, or more rarely an inherited condition that occurs due to a faulty gene. The new Nature Medicine paper provides the first evidence of Alzheimer’s disease in living people that appears to have been medically acquired and due to transmission of the amyloid-beta protein. The people described in the paper had all been treated as ...
