Phys.org / A simple ECG test could flag racehorses at risk of exercise arrhythmias
A quick heart trace taken during a warm-up trot could identify racehorses at risk of cardiac arrhythmias during high-intensity exercise, according to a new study led by the University of Surrey. The screening method analyzes ...
Phys.org / Artemis II's moonbound astronauts capture Earth's brilliant blue beauty as they leave it behind
The Artemis II astronauts have captured our blue planet's brilliant beauty as they zoom ever closer to the moon.
Tech Xplore / AI companions can comfort lonely users but may deepen distress over time
AI companions are always available, never judge, never tire and never demand anything in return. If someone is struggling with loneliness, this frictionlessness can seem profoundly appealing. However, new research shows that ...
Phys.org / Engineered tobacco plant can produce five psychedelics, including psilocybin and DMT
Compounds in psychedelic drugs like DMT, psilocybin, and psilocin are naturally produced in certain plants, fungi, and animals, and have a long history of use in spiritual and therapeutic contexts. Now, a considerable amount ...
Tech Xplore / Helping resolve quantum computers' memory problem
A major problem with quantum computers is memory, as the information they contain can be quickly lost. Quantum computers are not yet fully reliable—they are far too unstable. However, all around the world, people are trying ...
Medical Xpress / Smart sensor decodes fatigue and stress from body signals on the move
About one in three employees in Singapore report feeling burnt out—one of the highest rates globally. Burnout and chronic fatigue carry a substantial economic cost and pose serious risks in professions where alertness is ...
Medical Xpress / Stress tested, testing stress: Novel organoid models how the adrenal gland develops
Sitting above each kidney are two small endocrine glands about the size of walnuts. These are the adrenal glands, responsible for producing hormones that help control some of the body's most critical functions. Among these ...
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 ...
Tech Xplore / How a 'perfectly symmetrical' 2D perovskite could boost tandem solar cells
Rice University scientists and collaborators have created a new type of two-dimensional (2D) semiconductor that comes closer than ever to a "perfect" crystal. The findings, reported in the journal Nature Synthesis, could ...
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 / Ancient predator species discovered in South Africa challenges what we know about gorgonopsians
In a study published in The Anatomical Record, researchers have identified a new species of large-bodied gorgonopsian from the middle Permian. The discovery pushed back the known origins of when these apex predators began ...
