Phys.org / We discovered rare dinosaur tracks from the Coniacian age near Tumbler Ridge, British Columbia
Imagine the Western Plains of North America, from Texas to Alaska, submerged under a broad, shallow seaway. To the west lay the ancestral Rocky Mountains. To the east were low-lying plains traversed by large, sluggish rivers.
Phys.org / When the dust settles: Field experiments measure how everyday activity resuspends hazardous particles
Being prepared for an emergency is key to keeping people safe. This means more than just having supplies such as food, water and first-aid kits. Sometimes, the most important preparation is having the right data to help first ...
Phys.org / Observing the vibrations of neighboring atoms with an atomic-scale double slit
Efficiently controlling heat generation has become a major challenge as the semiconductors used in smartphones, computers and similar devices have become higher-performing and more miniaturized. The way heat is transmitted ...
Tech Xplore / 'End of an era': Players lament decline of the disc at Gamescom
Some video game fans are flabbergasted at Sony's decision, announced at Germany's Gamescom trade show, to discontinue disc sales starting in 2028—leading to calls for a boycott.
Phys.org / Some Galápagos 'yellow' sea turtles remain homebodies, surprising scientists
Sea turtles are famous for being prodigious wanderers. Guided by Earth's magnetic field, ocean currents and the sun, they tend to crisscross the seas in search of food, returning to the region of their birth every few years ...
Phys.org / Cellular 'glue' helps epithelial tissues engulf dead cells while staying sealed
A protein that sticks cells and tissues together has been found to have a surprising second job: helping cells that are packed into a continuous sealed layer, also known as epithelial cells, engulf nearby dead cells.
Medical Xpress / Fruit fly toolkit pinpoints neurons that suppress aggression
Our brains constantly integrate information about both our internal state and our surroundings to determine how we behave. Much of this coordination depends on neuromodulators—chemical messengers that establish how neurons ...
Phys.org / Geomimicry offers a new framework for engineering sustainable materials
When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning ...
Tech Xplore / US court rules Pentagon ban on Anthropic unlawful
A U.S. federal judge ruled Thursday that sanctions imposed by the Trump administration against AI giant Anthropic were illegal, finding that the government punished the company in a dispute over military use of its technology.
Phys.org / Reworked tRNAs enable protein design with up to 34 amino acids
Scientists have been hard at work for more than 20 years to instruct biological systems, such as E. coli cells, to produce proteins they don't naturally produce. Success could mean faster, cheaper, more innovative solutions ...
Medical Xpress / Almost a third of women in their 20s have never been screened for cervical cancer
The percentage of women in their 20s who have never been screened for cervical cancer has been increasing at a disturbing rate over the past 20 years—to the point that almost a third of women ages 21 to 29 have never been ...
Phys.org / How the sun's galactic journey and superflare-filled youth shaped Earth's climate
At the center of our solar system, the sun influences every planet that orbits it. In two recent studies, scientists uncovered how ancient events in the sun's history may have helped create Earth's unique climate and driven ...
