Phys.org / Avalanche cracks may appear globally supersonic while remaining locally subsonic
Can a crack be supersonic? Can the fracture that triggers an avalanche propagate faster than the limiting velocity predicted by classical fracture mechanics? The question remains the subject of debate within the scientific ...
Phys.org / NASA's Perseverance captures Phobos and Earth
This composite of seven images from the Mastcam-Z instrument aboard NASA's Perseverance Mars rover shows Earth, visible as a small bright dot moving from upper left to lower right, passing behind the Martian moon Phobos on ...
Medical Xpress / Early split in brain precursors creates two neuron lineages, mouse study finds
The cerebral cortex is densely packed with different nerve cells that enable us to perceive, think and act. Yet how these cell types arise as the brain develops is still not fully understood. Irene Varela-Martínez, a postdoctoral ...
Tech Xplore / Low-power AI chip cuts drone identification energy use by 88.7%
Doyeon Kim, an undergraduate researcher in the Department of Electronic and Electrical Engineering, has published a paper in an academic journal. The research focuses on implementing drone artificial intelligence (AI) identification ...
Medical Xpress / Taxi drivers rarely die of Alzheimer's. How complex mental maps and spatial reasoning protect your brain
Taxi and ambulance drivers are less likely than workers in almost any other job to die of Alzheimer's disease. That was the surprising result of a 2024 study examining the death certificates of nearly 9 million people in ...
Medical Xpress / Soluble signals released by neighboring cells direct how the human kidney is built
A human kidney is built once, before birth, and the rules guiding its construction have been largely inferred from animal models. Researchers at Penn Medicine have now read those rules directly in human tissue. They found ...
Medical Xpress / The neuroscience behind a 'runner's high'
While most runners are chasing a new goal or a personal best, some are chasing something slightly more elusive: a runner's high.
Medical Xpress / Cancer Dependency Map now includes next-generation 3D cancer models
For nearly a decade, the Cancer Dependency Map, or DepMap, at the Broad Institute has helped scientists uncover new cancer dependencies—the genetic changes some cancers need to thrive that can potentially be targeted by new ...
Phys.org / Measurements trace European wildfire smoke high into upper troposphere
The images of the major forest fires in Spain and France, with fire clouds near Bordeaux, have shocked many people. There have been numerous reports of the formation of a pyrocumulonimbus cloud—a fire-driven thundercloud—and ...
Phys.org / Scientists investigate continent-wide 'moisture conveyor belt' behind extreme monsoon rains
Weather scientists have long known that typhoons even hundreds of kilometers away from the Philippines can interact with the southwest monsoon, resulting in multiday heavy rains. But the exact dynamics of this relationship ...
Phys.org / Restoring the silenced Friedreich's ataxia gene through unconventional means
Cells can switch off genes by tightly packaging DNA around proteins called histones. However, scientists at St. Jude Children's Research Hospital have discovered that under certain conditions, this packaging acts more like ...
Phys.org / New museum find shows nature can't stop inventing seahorses
At first glance, it looks exactly like a seahorse. It has the same horse-shaped head tilted down from the body, the same curled, grasping tail and, in the males, a fully enclosed pouch for brooding the young.
