Phys.org / Cellular 'glue' helps epithelial tissues engulf dead cells while staying sealed
A protein that sticks cells and tissues together has been found to have a surprising second job: helping cells that are packed into a continuous sealed layer, also known as epithelial cells, engulf nearby dead cells.
Phys.org / Why ancient grasslands, once plowed, don't grow back the same
When a 10,000-year-old prairie is plowed up to plant corn or a savanna is consumed by a strip mall, these once-grassy expanses, if left to regrow, can eventually look vaguely like they did before. But a growing body of research ...
Phys.org / Why a newly formed lake is sparking fears of more flooding along the Nepal-China border
Even as rescuers worked through mud and debris Friday in areas devastated by a catastrophic flash flood along the Himalayan border between Nepal and China, authorities warned that a newly formed, overflowing lake could trigger ...
Tech Xplore / Bifur-circuits let shape-changing devices keep electrical connections intact
A new set of modular components allows users to create reconfigurable smart devices with electrical connections that keep working no matter what shape the structure forms.
Phys.org / Emperor penguin colonies reveal decades-long resilience and flexible breeding sites
With their charming waddles, heat-conserving huddles and tuxedo-like plumage, emperor penguins are among the world's most recognizable animals. Recent satellite surveys estimate that hundreds of thousands of the flightless ...
Phys.org / Electrically charged raindrops could be corroding metal with protective coatings
Electrically charged raindrops, a naturally occurring phenomenon, can break down surfaces treated with protective coatings, according to new research published in Nature. This previously overlooked corrosion mechanism highlights ...
Medical Xpress / Txn1 mutant rats: A valuable translational model of chronic kidney disease
Chronic kidney disease (CKD) is a major health burden affecting approximately one in 10 adults globally. Even with improved treatments, many patients continue to experience worsening kidney function, resulting in the need ...
Phys.org / A museum-shelf mystery reveals 6,500-year-old human tooth pendant in Serbia
More than 6,500 years ago, someone carefully drilled a hole in a human tooth, strung it on a cord and likely used it as a necklace. Found during field surveys at the Vinča cultural site of Jablanica in Serbia, the human tooth ...
Phys.org / Nepal's catastrophic flood shows disaster preparedness must be a shared responsibility
The catastrophic flood in Nepal and Tibet is a devastating reminder that disasters rarely occur in isolation.
Medical Xpress / Candida on urinary catheters can be more than contamination, patient samples suggest
Relying on a urinary catheter is a standard part of medical care for hundreds of thousands of patients each year. Unfortunately, the device carries the risk of catheter-associated urinary tract infections (CAUTIs), for which ...
Phys.org / Geomimicry offers a new framework for engineering sustainable materials
When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning ...
Tech Xplore / ScaFi: A robot that grows like a fish, not a machine—from 2 feet to nearly 10
Propeller-powered underwater vehicles have long helped scientists explore and monitor aquatic environments. But they're limited by their own mechanics: Spinning blades can snag on vegetation, stir up sediment and startle ...
