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 / From mountain peaks to microclimates, new maps bring satellite big data down to Earth
Zooming from her office, Michigan State University researcher Kelly Kapsar showed satellite images from across the United States. In some, different colors revealed the precise heights of the forested ridges in the Sierra ...
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 ...
Phys.org / US firm takes on backyard mosquitoes—with 600,000 mosquitoes
Todd Montgomery pops the lid off a small tube and taps out hundreds of mosquitoes into the backyard of a suburban home outside Washington.
Phys.org / Honduras review confirms 227 native mammal species after eight-year effort
An eight-year international research effort has produced the most comprehensive review of Honduras' mammals since 1998, verifying 227 native species across 146 genera and 42 families, along with three introduced rodent species. ...
Phys.org / JWST study suggests a handful of 'leaky' galaxies reionized the early universe
A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of "leaky" galaxies was responsible for cosmic reionization. The paper outlining this work ...
Phys.org / Fossil study finds vision—not the 'thinking' frontal lobe—drove varied brain development in primates
A new study led by a Duke University scientist overturns a long-held idea about how primates, including humans, came to have such large and sophisticated brains. The research finds that the dramatic expansion of the primate ...
Phys.org / New quantum microscopy trick quadruples microscope resolution
Three years after a team of Caltech scientists showed that pairs of entangled photons could double the resolution of a light microscope, the same lab has figured out a way to double down on that improvement. They have now ...
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 / AI for homework—parents more willing to pay subscriptions for their children as peer pressure rises
Many parents have mixed feelings about the unrestricted use of artificial intelligence (AI) for schoolwork. They are concerned about the potential impact on their child's ability to learn but also don't want them to be left ...
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 / An elegant modification doubles the range of low-noise 'white lasers' in a single fiber
Supercontinuum light sources—often called "white lasers" because they emit a broad, continuous rainbow of colors—are essential tools for everything from advanced medical imaging to environmental gas detection. However, researchers ...
