Phys.org / One snail, five slimes: Collagen and calcium reshape mucus for different jobs
Snails are particularly active after a rain shower. Even on the Max Planck Campus in Potsdam-Golm, common brown-lipped snails (Cepaea nemoralis) leave behind shiny trails of mucus. Researchers from the "Biomaterials" department ...
Tech Xplore / When security becomes a risk factor—privacy risks of public URL-scanning services
URL scanning services are now a common component of modern security workflows. They help detect phishing websites or malware early and warn users before they visit a URL. However, the practice of some of these services—publishing ...
Medical Xpress / Alzheimer's-linked tau disrupts mitochondria, reversing electron flow in nerve cells
A protein named tau, which has been strongly implicated in the world's No. 1 cause of dementia—Alzheimer's disease—and several other neurodegenerative disorders, may spur these diseases in a way that differs greatly from ...
Medical Xpress / AI-designed E. coli killer points toward new ways to fight antibiotic-resistant bacteria
In science, the suffix "phage" means to devour. Thus, the name bacteriophage might conjure images of tiny creatures that "eat" bacteria. While that conception isn't 100% scientifically accurate, bacteriophages are lethal ...
Phys.org / A 21-hour dip could help explain Tabby's star's decade-long dimming mystery
Since 2016, an ordinary-looking F-type star called KIC 8462852, nicknamed Tabby's star, has behaved anything but ordinarily. In a new study published in the Monthly Notices of the Royal Astronomical Society on July 6, researchers ...
Phys.org / Researchers demonstrate first fully solution-processed solid-state polariton laser
Researchers have demonstrated a solid-state organic laser microcavity fabricated entirely by solution processing. The device operates in the strong light–matter coupling regime, where light and matter form hybrid states called ...
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 ...
Phys.org / Charting the galaxy: Milky Way Mapper survey releases latest all-sky spectra
The Sloan Digital Sky Survey V (SDSS-V) has announced its 20th public data release (DR20), delivering a dramatic expansion of the Milky Way Mapper (MWM) scientific survey—the most detailed spectroscopic map yet assembled ...
Phys.org / Milky Way-like simulation reveals how central galactic structures grow together
Understanding the formation and evolution of the centers of galaxies is one of the most intriguing challenges in astrophysics. The new study aims to unveil the physical processes that led to the formation of two striking ...
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 / Physicists trace solar outbursts that led to historic Mother's Day storms
On Mother's Day weekend in May 2024, Earth experienced its most powerful geomagnetic storm in two decades, spawning auroras—the ribbony bands of light in the nighttime skies in the Northern and Southern hemispheres—that may ...
Phys.org / Just 50°C decides whether an ultrathin magnetic film stays flat or falls apart
Magnetic storage technologies, which store information in the direction of magnetization, play an essential role in modern data storage. Hard disk drives (HDDs) are widely used for long-term storage, while nonvolatile magnetic ...
