Phys.org / How flatworms keep their regeneration powers on track
Scientists have discovered a key biological safeguard that helps one of nature's most impressive regenerators, the planarian flatworm, correctly rebuild its organs. The new research, published in Nature Communications, illuminates ...
Tech Xplore / A 270-year-old physics trick could supercharge affordable battery technology
Roughly 270 years ago, Dr. Johann Gottlob Leidenfrost from Germany observed a peculiar behavior of water droplets on heated metal surfaces. In his manuscript, "A Tract About Some Qualities of Common Water," he described how ...
Phys.org / Antarctica has lost 10 times the size of Greater Los Angeles in ice over 30 years, satellite data reveal
A comprehensive 30-year study led by University of California, Irvine glaciologists has produced a circumpolar ice grounding line migration map of Antarctica. An amalgamation of three decades of satellite data compiled and ...
Phys.org / Ultrasound-activated 'nanoagents' kill superbugs hiding in biofilms
Scientists have designed nanoagents that act like smart drug-delivery capsules—carrying an antibiotic deep into bacterial infection sites and releasing it only when activated by gentle ultrasound. Delivering antibiotics ...
Medical Xpress / Rectal cancer incidence rising after decades of decline as colorectal cancer shifts toward younger generations
Colorectal cancer rates in the United States are moving in two very different directions, according to a new report released today from the American Cancer Society (ACS). While the disease continues to decline among older ...
Tech Xplore / 'Milestone' findings on imaging methods call for a closer look at battery microscopy
Transmission electron microscopes (TEMs) allow researchers at the forefront of energy technology to study next-generation battery materials down to the atom. But new research has discovered that the very act of microscoping ...
Tech Xplore / A clear view to better batteries: Engineers show moment lithium-ion batteries begin to fail
Lithium-ion batteries are ubiquitous in consumer electronics such as cellphones and in electric vehicles, but the surrounding temperature and speed of charging affect those batteries' performance, safety and lifespan. Fast ...
Medical Xpress / AI cancer tools may rely on 'shortcut learning' rather than genuine biological signals
Artificial intelligence tools are increasingly being developed to predict cancer biology directly from microscope images, promising faster diagnoses and cheaper testing. But new research from the University of Warwick, published ...
Tech Xplore / A rewritable DNA hard drive may help solve the growing data storage crisis
Around the world, scientists are exploring an unexpected solution to the growing data crisis: storing digital information in synthetic DNA. The idea is simple but powerful—DNA is one of the most compact, durable information ...
Phys.org / MeerKAT discovers record-breaking cosmic laser halfway across the universe
Astronomers using the MeerKAT radio telescope in South Africa have discovered the most distant hydroxyl megamaser ever detected. It is located in a violently merging galaxy more than 8 billion light-years away, opening a ...
Medical Xpress / How dysfunctional packaging of dopamine advances symptoms of Parkinson's disease
A new study shows how dysfunctional packaging of the neurotransmitter dopamine triggers toxic processes in neurons—and how this can be repaired with simple delivery of energy (ATP). Parkinson's gradually destroys dopamine-producing ...
Phys.org / A crystal that 'comes alive': Heat-driven bubbles push it forward while it changes fluorescence color
In a study published in Angewandte Chemie International Edition, researchers from National Taiwan University report that a seemingly solid, nonporous organic crystal can undergo dramatic structural and mechanical transformations ...
