FRBs are among the most puzzling phenomena in astronomy, but locating where they…
Researchers at New York University Abu Dhabi (NYUAD) have discovered new clues suggesting that water once moved beneath the surface of Mars. The findings indicate that the Red Planet may have remained capable of supporting life for much longer than scientists once believed. The research, published in the Journal of…
Findings from a large study led by Mass General Brigham suggest scientists should continue investigating whether vitamin D supplements could influence long COVID. The research showed that taking high doses of vitamin D3 did not make COVID-19 infections less severe, but it may have a possible connection to long COVID…
Sharp increases in food prices during economic crises tend to hit certain groups the hardest. Urban residents and families with lower levels of education are often especially vulnerable. These price shocks can lead to long term health problems, including stunted growth in children. Researchers at the University of Bonn recently…
In regions where freshwater supplies are limited, farmers sometimes rely on treated wastewater to water their crops. While this practice helps conserve scarce water resources, it has raised concerns among regulators and consumers. Wastewater can contain trace amounts of various substances, including psychoactive medications commonly used to treat mental health…
New research published in the Journal of the Endocrine Society suggests that a father’s nicotine exposure could influence how his offspring process sugar. In a mouse study, scientists found that paternal nicotine intake led to metabolic changes in the next generation. These alterations may affect how the body handles glucose…
Researchers at Houston Methodist have discovered that a protein tied to neurodegenerative conditions such as dementia and amyotrophic lateral sclerosis (ALS) also helps control a critical DNA repair process. This repair system, known as DNA mismatch repair, corrects mistakes that occur when cells copy genetic material. The discovery suggests that…
Researchers have identified previously unknown DNA-binding proteins in some of the most extreme places on Earth and demonstrated that they can enhance rapid medical tests used to detect infectious diseases. The international team was led by Durham University and included collaborators in Iceland, Norway, and Poland. The scientists examined genetic…
A research team led by Universitat Autònoma de Barcelona (UAB) scientist David Reverter has identified the molecular mechanism that regulates bacterial cell division. The discovery reveals how the MraZ protein binds to the dcw gene cluster to control this process. The findings were published in Nature Communications. Cell division is…
Mars looks very different today than it did billions of years ago. Scientists believe the planet once had flowing water, a thicker atmosphere, and a much warmer climate. Now the Red Planet is frigid, dry, and surrounded by only a thin layer of air. Researchers think the biggest reason for…
A rugged Martian landscape that resembles a giant spiderweb when seen from orbit may hold important evidence about the history of water on ancient Mars. For roughly six months, NASA’s Curiosity rover has been studying an area covered with geological features known as boxwork. These formations appear as narrow ridges…
Members of the arachnid class — think spiders, scorpions and harvestmen (daddy long legs) — often trigger feelings of fear or disgust. Despite this reaction, these animals play an essential role in maintaining healthy ecosystems. As global biodiversity declines, including what some researchers describe as an “insect apocalypse,” two ecologists…
Researchers at the University of Maryland have developed Smart Underwear, the first wearable device designed specifically to measure human flatulence. The small sensor tracks hydrogen in flatus, allowing scientists to reexamine long held assumptions about how often people pass gas. The technology also offers a new way to observe gut…
New research suggests human hair does not grow by being pushed out from the root as long believed. Instead, scientists found that hair is pulled upward by forces created by a hidden network of moving cells within the follicle. The discovery challenges decades of biology textbook explanations and could influence…
Far beneath the surface of the Greenland ice sheet, scientists have identified enormous swirling structures that resemble rising plumes. These strange formations have puzzled researchers for more than a decade. Now, scientists from the University of Bergen (UiB) believe they have finally uncovered an explanation by using mathematical models similar…
Researchers at the University of Cambridge have created a new technique that uses light instead of toxic chemicals to change complex drug molecules. The discovery could speed up drug development and make the process of designing medicines more efficient. The study, published on March 12 in Nature Synthesis, introduces what…
Most people are familiar with the idea of deep space, but scientists also study something called deep time. Advances in genetics now allow researchers to trace biological changes far deeper into the past than previously possible. Even with these powerful tools, many questions remain unanswered. One long standing puzzle has…
Irritable Bowel Syndrome (IBS) is a widespread digestive condition that affects the gastrointestinal tract. It occurs more frequently in women and commonly causes symptoms such as abdominal pain, constipation, or diarrhea. The exact cause of IBS remains uncertain. However, scientists believe that conditions inside the intestine, including the gut microbiota…
Researchers have given a newly identified Australian tree species an unusual nickname. Scientists call it the “zombie” tree because, although some individuals are still alive, the species is unable to grow and reproduce normally without major intervention. Professor Rod Fensham, a botanist at the University of Queensland, said urgent action…
Tiny fragments of plastic known as microplastics may be contributing to neurodegenerative conditions such as Alzheimer’s and Parkinson’s disease.
