Tech Xplore / AI chatbots are helping people communicate with dating partners. Here are some do's and don'ts
Whether you love or loathe generative AI chatbots, they're becoming increasingly involved in the business of romance.
Phys.org / AI reads 3D tooth microwear to reconstruct diets of early human ancestors
The study of dental microwear allows the analysis of the microscopic marks that foods leave on the surface of tooth enamel during mastication. In paleoanthropology, this methodology helps reconstruct the diet of fossil primates ...
Phys.org / Laser experiments push helium to record shock pressures
Deep inside gas giants like Jupiter and Saturn, hydrogen and helium coexist under pressures millions of times greater than Earth's atmosphere. Under those conditions, helium may separate from hydrogen and influence a planet's ...
Phys.org / Hubble spies ancient 'Chandelier Cluster' forming stars in two bursts
The subject of today's NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound ...
Phys.org / Oldest known asteroid impact on Earth dated to 3 billion years
Curtin University researchers have determined the most precise age yet for the oldest known impact crater on Earth, providing new insight into how meteorite strikes shaped the planet during its earliest history.
Phys.org / Brain growth may explain why birds lay outsized eggs compared with dinosaurs
A new study has uncovered a fundamental link between brain size and offspring size, helping to solve a long-standing evolutionary puzzle: Why do birds lay such disproportionately large eggs?
Phys.org / Turtles may migrate using Earth's magnetic field
New research indicates that sea turtles seem to navigate across hundreds of miles of open ocean using Earth's magnetic field. Previous experimental studies suggested that sea turtles use geomagnetism to navigate, but this ...
Tech Xplore / Light-controlled microgripper bridges the gap between precision and force
For some time, researchers have used optical tweezers to manipulate tiny objects with incredible precision, using carefully controlled beams of laser light. So far, however, this technique has always come with strict limits ...
Phys.org / Megacluster of bacterial genes reveals four antibiotics that jointly starve rivals of biotin
Researchers at McMaster University have discovered what they describe as a "megacluster" of genes in Streptomyces bacteria that produces four antibiotics that work together to stop rival bacteria.
Tech Xplore / Plain-language AI workflow tool could cut cloud energy use and costs dramatically
Agentic workflows are artificial intelligence-powered software systems that chain together multiple models and external tools to tackle complicated tasks, like analyzing a video and answering questions about it. But the way ...
Phys.org / Human DNA can survive on cave walls for thousands of years, opening new window into prehistory
For the first time, scientists have shown that ancient human DNA can survive for thousands of years on cave walls, opening new ways to study prehistoric human activity. This interdisciplinary study was conducted within the ...
Phys.org / Antibiotics trigger bacterial teamwork, boosting survival through shared proteins
When bacteria are under antibiotic attack, it is not "every man for himself." Researchers at Baylor College of Medicine and colleagues from collaborating institutions have discovered that bacterial populations work as a team ...
