Phys.org / One ant can trigger colony-wide activity bursts, mathematical model suggests
Scientists have long known that ant colonies sometimes seem to move as one. A nest that appears quiet can suddenly erupt into activity, with workers throughout the colony springing into motion almost simultaneously before ...
Phys.org / New models shed light on how an exotic phase of hydrogen in Earth's core may behave
While Earth's core consists mostly of iron, its density implies that lighter elements are also mixed in. Because hydrogen is abundant in the universe and can mix with iron under certain conditions, scientists suspect it makes ...
Tech Xplore / EU tells Meta, TikTok to boost monitoring, fact-checking
The EU's tech chief called on Meta and TikTok to "act decisively" to stem disinformation at times of crisis, saying the European Commission held talks with both platforms Friday following last week's Ceuta migrant surge.
Tech Xplore / Pagoda-inspired floors reduce tower sway while cutting material needs
Imperial and Arup pioneer a new approach to designing tall buildings that uses the building's own weight to reduce movement in high winds and earthquakes. Inspired by traditional Japanese pagodas, it makes towers safer while ...
Phys.org / Liquid nitrogen may have recently flowed across Pluto's heart-shaped glacier
A new study led by Southwest Research Institute (SwRI) provides evidence that liquid nitrogen is rising to Pluto's surface through cracks at the northern edge of Sputnik Planitia, part of the massive heart-shaped glacier ...
Medical Xpress / Social media algorithms expose many adolescents to self-harm content, study finds
Digital technologies have profoundly transformed how adolescents acquire information and interact with each other outside school. Numerous preteens and teenagers worldwide access social media platforms daily to read posts, ...
Phys.org / AI and 'Ramanomics' could eliminate a major obstacle to studying living cells
Fluorescent dyes have long been used in biological research to identify and visualize structures within living cells. Although effective, they have several drawbacks, including altering the cells under study, limiting the ...
Phys.org / Atomic view of Alzheimer's disease peptide could inform new drugs
One of the hallmarks of Alzheimer's disease is the accumulation of a peptide in the brain known as amyloid beta. A new study published in Nature Communications on July 22 has uncovered the atomic structure of the peptide ...
Phys.org / A new species of Ice Age toad discovered at La Brea Tar Pits: The spadefoot toad Spea labreae
For the first time, researchers have discovered a new species of extinct amphibian from Ice Age Los Angeles at La Brea Tar Pits: a spadefoot toad they have named Spea labreae. Only one other extinct Pleistocene amphibian ...
Medical Xpress / Scientists discover a brain cycle that may explain why learning eventually stalls
For many who have struggled to learn a new language or instrument, it's a familiar pattern: They make rapid progress at first, then hit a plateau that no amount of diligent practice or concentration seems to break.
Phys.org / Bioengineers develop biochemical halo to cloak insulin-producing cells from body defenses
A protein known as interleukin 10 (IL-10) is the lynchpin of a new method to protect transplanted cells from host immune system attacks. Rice University researchers engineered a living factory to produce a localized biochemical ...
Phys.org / Webb reveals warped structure in nearby TW Hydrae's protoplanetary disk
Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July ...
