Do you sometimes notice a deep buzzing or humming sound that you can’t pinpoint the source of? If so, you may be one of the estimated 2-4% of people worldwide who experience this unusual sound. Researchers have spent decades trying to determine its origins. For some people, noise is irritating but manageable. For others, infrasound can cause physical discomfort or illness, and can also feel like vibrations traveling through the body. Hum can be difficult to detect outdoors. They are often seen inside buildings, especially at night when people are trying to sleep. If someone were to go outside and…

New research published in American Political Science Journal This suggests that support for authoritarian leaders can be socially widespread among citizens of established democracies. Researchers found evidence that by exposing individuals to peers with different political views, people tend to adjust their preferences for the rule of the strong to match the attitudes of those around them. This social contagion effect provides insight into how anti-democratic sentiment can suddenly surge in modern societies. The growing popularity of leaders who circumvent democratic institutions has led experts to examine how ordinary citizens form political preferences. In recent years, many modern democracies have…

An analysis of Health and Retirement Study data found that higher levels of optimism were associated with a slightly lower risk of developing dementia over a study period of up to 14 years. This association remained even after the study authors took into account health behaviors, adjusted for possible reverse causality (the possibility that optimism is lower in the early stages of dementia), and excluded individuals with the poorest mental health. The paper was published in. Journal of the American Geriatrics Society. Optimism is the general tendency to expect favorable outcomes and believe that difficulties can be managed or overcome.…

Coffee has been repeatedly linked to longevity and lower risk of some chronic diseases. Still, scientists don’t fully understand the biological processes that may explain these benefits. New findings from the Texas A&M College of Veterinary and Biomedical Sciences (VMBS) point to one possible answer. Researchers have discovered that certain compounds in coffee can activate NR4A1, a receptor that is becoming increasingly important in research into aging, stress responses, and disease. This research recently nutrientsproviding one of the first direct links between coffee compounds and NR4A1. This association may help explain some of the widespread health effects associated with drinking…

A newly identified branch of the marsupial family tree adds a surprising twist to the history of Australia’s most distinctive mammals. The discovery suggests that their evolution was more complex and more mysterious than scientists previously understood. Marsupials first arrived in Australia over 55 million years ago. Since then, they have spread into an amazingly wide range of habitats and lifestyles. Today, they include about 160 species, from highland animals (like thumb-sized possums that sleep through the winter) to desert specialists in the Red Center, such as tiny moles with pink fur and eyes that spend their entire lives underground.…

A rare type of meteorite known as a CO chondrite may be the object that crashed into Earth 66 million years ago and caused the extinction of about 75 percent of all species, including all non-avian dinosaurs. Researchers from the University of British Columbia (UBC), Paris, Brussels, and Vienna reached that conclusion by analyzing nickel isotopes preserved in material left behind by the Cretaceous-Paleogene collision. Their discovery is scientific progress. The rare meteorite behind the extinction of dinosaurs “Ornans-class carbonaceous chondrites are clearly different from the typical meteors found in museum collections,” says Dr. Philip Claeys, who worked on the…

A widely available antidepressant drug may provide meaningful relief for people experiencing persistent fatigue from long-term COVID-19 infections, according to a global clinical trial co-led by McMaster University. Researchers have found that fluvoxamine (sold under the brand name Luvox), an inexpensive drug already commonly used to treat depression and other symptoms, reduces fatigue and improves quality of life in adults with long-term COVID-19 infections. This randomized, placebo-controlled trial Annual report of internal medicine. Possible treatment for long-term coronavirus fatigue Fatigue is one of the most frequent and disabling symptoms reported by people with long-term COVID-19 infection. For some people, fatigue…

Microplastic pollution has become a global cleanup problem with no clear end point. Filtration can capture some particles, dredging removes contaminated sediment, and chemical treatments can change certain polymers, but these interventions are expensive, incomplete, and often move plastic from one place to another rather than destroying it. A new scientific review claims the most promising alternative may come from organisms too small to see. “Microbial bioremediation of microplastic pollution for sustainable ecosystems and a greener future: A review” Published in applied microbiologyinvestigates how bacteria, fungi, microbial communities, and plastic-degrading enzymes can potentially break down synthetic polymers and convert their…

A new analysis of brain imaging data reveals that lysergic acid diethylamide, commonly known as LSD, reduces the synchronization of local brain activity, producing mind-altering effects. The study, published in the European Journal of Neuroscience, suggests that psychedelics interact with a wider range of brain receptors than previously thought. These insights may help map the biological mechanisms underlying altered states of consciousness and inform future therapeutic uses of psychedelics. Over the past decade, medical researchers have renewed their focus on classic psychedelic drugs as potential treatments for mental illness. Compounds such as LSD and psilocybin cause significant changes in perception,…
