About The Study: Electric fan use did not lower peak core temperature in older adults exposed to extreme indoor heat. Reductions in end-exposure core temperature and heart rate were observed, but they were small and of questionable clinical importance. Neither exceeded previous suggestions for clinical significance. Consistent with recent modeling, these data do not support fans as an efficacious standalone cooling intervention for older adults in hot indoor environments (>33-35 °C).

Dusty ice exposed at the surface of Mars could provide the conditions necessary for the presence of photosynthetic life, according to a modelling study. The findings, published in Communications Earth & Environment, suggest that ice deposits located in the planet’s mid-latitudes should be a key location in any search for life on Mars. High levels of harmful ultraviolet radiation from the Sun make current life on the surface of Mars almost certainly impossible. However, a sufficiently thick layer of ice can absorb this radiation and could protect cells living below its surface. Any life in these conditions ...

CHAMPAIGN, Ill. — By combining visible light and electrochemistry, researchers have enhanced the conversion of carbon dioxide into valuable products and stumbled upon a surprising discovery. The team found that visible light significantly improved an important chemical attribute called selectivity, opening new avenues not only for CO2 conversion but also for many other chemical reactions used in catalysis research and chemical manufacturing. One way that chemists recycle CO2 into valuable products is through a process called electrochemical reduction, where a stream of CO2 gas moves through an electrolysis cell that breaks the CO2 and water ...

The first randomized, placebo-controlled clinical trial evaluating the impact of therapeutic monoclonal antibodies on the risk of developing long COVID was led by researchers at Weill Cornell Medicine. The study, published Sept. 1 in eClinicalMedicine, details an international, multicenter phase 2/3 clinical trial that found a combination of amubarvimab and romlusevimab did not reduce the occurrence of long COVID symptoms. Lasting weeks or even months after SARS-CoV-2 infection, long COVID is characterized by a variety of symptoms that affect each person differently. These include extreme fatigue, difficulty concentrating, ...

Super-spy James Bond is a prime example of ‘regressive nostalgia’ highlighting how certain consumer groups cling to idealised past versions of brands and resist attempts to move with the times, a new study reveals.  Researchers examined the James Bond movie franchise - a cultural icon for over 70 years - and discovered that some ‘super-consumers’ react negatively to modern portrayals of the fictional British secret agent that reflect contemporary societal values.   Whilst loyal to the brand, these consumers prefer traditional, more exclusionary, versions of Bond which most closely follow author Ian Fleming’s original 1950s and 1960s vision – ...

Biofilms — slimy communities of bacteria — grow on all sorts of surfaces: from glaciers and hot springs to plant roots, your bathtub and fridge, wounds, and medical devices such as catheters. Most biofilms are composed of multiple bacterial species, but how these species manage to live together is unclear. A new study by Dartmouth scientists in Current Biology uses experiments and modeling to delve into how three species of biofilm bacteria coexist — and when they move out on their own. One species, Pseudomonas aeruginosa, a verstaile pathogen known to be antibiotic resistant, dominated ...

COLUMBUS, Ohio – The microbes that cycle nutrients in the ocean don’t do the work on their own – the viruses that infect them also influence the process. It’s a vital job for the rest of the planet, enabling oceans to absorb half of the human-generated carbon in the atmosphere and produce half of the oxygen we breathe. A new study gets scientists closer to more fully understanding where viruses fit into the global ocean picture of cycling nutrients such as nitrogen, phosphorous and, of particular interest, carbon. The research broadly expands on a 20-year-old finding that genes can be exchanged between viruses and the photosynthetic ...

The Earth is an almost unimaginably diverse planet in terms of species. Researchers have identified between two and three million species, but there are many more that we know nothing about. The unknown species are called ‘biological dark matter’, borrowing a term from astrophysics.  “We want to demonstrate how we can gain a better overview of biological dark matter by using DNA barcoding,” said Associate Professor Emily Hartop. DNA barcoding, in this case so-called ‘megabarcoding’, might sound mysterious, but it isn’t really. We will come back to that later. First, let us take a look at why ...

WASHINGTON — Americans believe volunteering to help strangers contributes more to society than providing care for family or friends, even though they contribute billions of dollars’ worth of labor in unpaid caregiving every year, according to research published by the American Psychological Association. This perception could lead Americans of lower socioeconomic status to feel like they have less to contribute than people of higher socioeconomic status, because they often do not have the same amount of time or resources to devote to people outside of their communities. “Over ...

Researchers at the University of Zurich (UZH) have used artificial intelligence (AI) to help identify antibiotic-resistant bacteria. The team led by Adrian Egli, UZH professor at the Institute of Medical Microbiology, is the first to investigate how GPT-4, a powerful AI model developed by OpenAI, can be used to analyze antibiotic resistance. The researchers used AI to interpret a common laboratory test known as the Kirby-Bauer disk diffusion test, which helps doctors to determine which antibiotics can or can’t fight a particular bacterial infection. Based on GPT-4, the scientists created the “EUCAST-GPT-expert”, which follows strict EUCAST ...

Imagine you wake up in a hospital without a single memory of the last month. Doctors say you had a series of violent episodes and paranoid delusions. You’d become convinced you were suffering from bipolar disorder. Then, after a special test, a neurologist diagnoses you with a rare autoimmune disease called anti-NMDAR encephalitis. This is what happened to Susannah Cahalan, a New York Post reporter who would go on to write the best-selling memoir Brain on Fire: My Month of Madness. Anti-NMDAR encephalitis can lead to hallucinations, blackouts, and ...

Woods Hole, Mass.(Oct. 17, 2024)  — Scientists at the Wood Hole Oceanographic Institution (WHOI) have been working for years to find out what types of plastics have the shortest and longest lifespans in the ocean, and what types of plastic products, like straws and food wrappers, most commonly contribute to plastic pollution. With more biodegradable materials being developed , like cellulose diacetate (CDA)—a plastic-like polymer derived from wood pulp—researchers are racing to ensure they can replace traditional plastics without causing harm to ocean ...
