Phys.org / High nickel concentrations in Martian bedrock point to potential biosignatures
In 2024, NASA's Perseverance rover found surprising levels of Nickel in the Martian bedrock of an ancient river channel, called Neretva Vallis, which flowed into the Jezero crater. A new study, published in Nature Communications, ...
Phys.org / Gravitational waves suggest a 'forbidden zone' for stellar-origin black holes
An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive ...
Phys.org / Why cats stop eating—it's not just fullness
Why do cats often leave food unfinished? Many cat owners have experienced this puzzling behavior. Domestic cats are well known for eating multiple small meals throughout the day, a pattern thought to reflect their evolutionary ...
Tech Xplore / New memristor design uses built-in oxygen gradient to bring stability to reinforcement learning
In a recent study published in Nature Communications, researchers created a memristor that uses a built-in oxygen gradient to produce slow, stable conductance changes, enabling a reinforcement learning (RL) algorithm to learn ...
Medical Xpress / How one 'forever chemical' can disrupt a baby's facial development
Researchers have long associated per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," with certain severe birth defects, but exactly how these pollutants harm a developing fetus has remained ...
Phys.org / How the octopus uses its 'taste by touch' sensory system to feel out potential mates
A new study by Harvard biologists reveals how octopuses feel their way to potential mates with a "taste by touch" sensory system and can even couple at arm's length without actually seeing each other. In a study featured ...
Medical Xpress / A fast, accurate test enables improved assessment of airborne chemical risk to human lungs
A multidisciplinary research team has identified a faster way to determine which airborne chemicals pose a threat to human lungs. Led by an environmental health researcher with the Texas A&M University School of Public Health, ...
Phys.org / Q&A: What drives the rise in red tides that threaten human health?
With its striking San Francisco Bay settings, director Alfred Hitchcock's iconic horror film "The Birds" has captivated audiences for more than 60 years. For Hitchcock, the film—set in an ocean-side town terrorized by swarming, ...
Medical Xpress / High‑fat diets linked to rapid decline in protective gut immune cells
In a preclinical study from Mass General Brigham, researchers have found that even short-term exposure to high levels of dietary fat results in a quick and selective loss of critical gut immune cells called ILC3s, promoting ...
Medical Xpress / New study aims to help NHS turn ideas into action quicker
Researchers from the University of Aberdeen and NHS Grampian have developed a new, practical approach to help NHS Health Boards plan and implement innovation more effectively—in spite of increasing pressures on time, workforce ...
Phys.org / Terraforming Mars: Modeling engineered aerosols to warm the planet
Whenever humans arrive on Mars, they're going to find it a difficult place to exist. Mars is cold, with an average surface temperature of -55°C; temperatures can plunge to -125°C with dust storms lasting months; its atmosphere ...
Phys.org / Microscopic mechanism of 'quantum collapse' in real-world environments uncovered for the first time
A research team has, for the first time in the world, elucidated the microscopic mechanism by which quantum order is lost and collapses in "open quantum environments" existing in nature. Since perfectly isolated quantum systems ...
