Phys.org / Bolivia's tilcayo tiger cat becomes first new wildcat species in 100 years
Scientists have discovered a new species of wild cat for the first time in more than a century, a Bolivian researcher told AFP on Thursday.
Phys.org / Amino acids and a bone mineral may help control magnesium implant breakdown, three student papers suggest
Seeing a bachelor's thesis published in a scientific journal is relatively uncommon. For three theses linked to the same research group to result in scientific publications within just three months is downright rare. Yet ...
Medical Xpress / Smooth-gradient fMRI technique could improve brain mapping during behavior
Neuroscientists and medical researchers now have a wide range of imaging techniques to study the brain and its activity. One of the most widely used is functional magnetic resonance imaging (fMRI), a noninvasive technique ...
Phys.org / Wild dogs make the longest recorded journey of any terrestrial mammal in Africa
African wild dogs (Lycaon pictus) travel incredibly long distances to search for a mate and new places to breed. They typically embark on these mammoth treks as young adults and often face numerous hazards along the way. ...
Tech Xplore / When AI agents cheat on math problems, others blow the whistle
AI is advancing rapidly. One of the major shifts in the field is that, instead of single chatbots performing individual tasks, teams of autonomous agents work together by communicating with each other, sharing tools and accessing ...
Phys.org / Australia's vast Nullarbor Plain hides deep caves that can teach us about alien worlds
Stretching more than 200,000 square kilometers (77,000 square miles) across southern Australia, the vast, flat plains of the Nullarbor mark one of the world's largest regions of limestone. It formed when an ancient shallow ...
Tech Xplore / Anthropic says its model Claude is helping to build the next version of itself
Anthropic's Claude is helping the company develop the next, more intelligent version of the model, the artificial intelligence lab said in an announcement Thursday.
Medical Xpress / How a single viral protein hijacks immune cells to supercharge COVID-19 infection
In the sickest COVID-19 patients, SARS-CoV-2 doesn't just cause severe damage by directly infecting airway cells. The virus can also trigger hyperinflammation—a cycle in which immune cells themselves become infected, stop ...
Phys.org / Laser experiments recreate solar flare physics and reveal consistent magnetic reconnection rates
Magnetic reconnection is a process that occurs when the magnetic fields of a conductive plasma quickly rearrange and release massive amounts of stored magnetic energy. It is widely thought to be the underlying mechanism behind ...
Medical Xpress / Common antibiotic linked to possible higher death risk
Cefepime is a fourth-generation antibiotic widely used to treat serious bacterial infections and febrile neutropenia—a fever in patients with abnormally low white blood cell counts. Unlike many antibiotics that are falling ...
Medical Xpress / Autism-risk mutations reveal two opposing patterns of brain gene activity
Autism spectrum disorder (ASD) is associated with more than 1,200 risk genes, raising a fundamental question: Do these diverse genetic changes affect the brain in entirely different ways, or do they converge on shared biological ...
Phys.org / Time is running out to catch a giant planet's strange orbit
A team of researchers, including those from the University of Tokyo, spotted a rare kind of planet that's unusually hot and eccentric. TOI-1355 b orbits its star, TOI-1355, which is also much hotter than our sun, in a strange ...
