Phys.org / Newly identified C/EBPγ protein links cancer cell plasticity and DNA repair
A research team has identified the transcription factor C/EBPγ as a novel regulator that simultaneously promotes epithelial-mesenchymal transition (EMT) and DNA double-strand break repair in lung adenocarcinoma cells. The ...
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 ...
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 / 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 / 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 / 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 ...
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 ...
Phys.org / Observing key material properties atom by atom for the first time
Many material properties depend on how electrons are arranged inside a material. Their distribution determines, for example, whether a material conducts electricity or displays magnetic behavior. Understanding how electrons ...
Phys.org / Mitochondria act as sensors for essential iron molecule, study reveals
Heme, a bioactive form of iron, has numerous essential functions in the cell. As a key component of hemoglobin, it enables oxygen transport in the blood. In addition, it performs important functions in other proteins in processes ...
Phys.org / How winter canola could profit Illinois farmers, improve sustainability
A new simulation study from the University of Illinois Urbana-Champaign suggests winter canola could be profitable and environmentally beneficial if added to a conventional corn-soy rotation in the U.S. Midwest.
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 ...
