Phys.org / Different genes, same result: How flies evolved multiple ways to define heads and tails
One of the most important milestones in the early life of an organism is when the embryo breaks symmetry and arranges itself to form the head (anterior) at one end and tail (posterior) at the other end. Scientists have used ...
Medical Xpress / Brain activity reveals two stages of visual processing before conscious perception
Seeing feels immediate; we open our eyes and the world seems to appear as a continuous stream. But some visual illusions show that events occurring later can change how we perceive what happened earlier, suggesting that the ...
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 ...
Phys.org / Laser spectroscopy helps reveal hidden nuclear properties in fermium
For the first time, researchers have determined the shape of the actinide nucleus of fermium-255 and measured its structure with high precision and resolution.
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 / 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 / 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 / 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 ...
Tech Xplore / 'Chameleon' chip adapts to changing data speeds, cutting prediction errors by up to 40-fold
AI semiconductors are becoming more programmable. KAIST researchers have developed a device whose response characteristics can be programmed to process data that changes at different speeds. The technology reduced prediction ...
Phys.org / The creatures born from code: Generative AI threatens to upend citizen science records
You need to tread carefully among the leaf litter of the Indonesian scrubland and its tropical rainforests. The dead leaves might seem caught in a gentle breeze, but there's more here than meets the eye. Try plucking one ...
Medical Xpress / Protective drug dexrazoxane reduces heart damage in pediatric cancer survivors years after treatment ends
A new study reveals that the cardioprotective drug dexrazoxane significantly reduces heart damage caused by chemotherapy in pediatric cancer patients 15 years or more after treatment ends.
