Tech Xplore / Simple robot design exceeds human hand in some core motions
The human hand is a dexterous and versatile machine. Scientists have conventionally tried to replicate these traits in robots by copying the biological mechanics of the hand, resulting in complex and difficult-to-control ...
Phys.org / 'Imposing ignorance': US climate science under siege
A benchmark U.S. report on the fast-changing state of the Arctic has been canceled. The nation's top research body has removed a chapter on global warming from a reference manual for judges.
Phys.org / Uniaxial strain reveals new way to tune electron flow in altermagnet material
Altermagnetism is a new, third type of magnetism of great interest for spin-transport applications like computer memory. If properly harnessed, it could combine the benefits of the two existing types of magnetism, ferromagnetism ...
Phys.org / A 236-million-year-old fossil challenges the story of mammalian live birth
Some cynodonts may have been giving birth to live young much sooner in evolutionary history than previously assumed. A new Frontiers in Mammal Science study has offered the first compelling evidence that cynodonts may have ...
Phys.org / Germany's dry rivers spark battle over engineering vs. restoration
As a heat wave dries Germany's rivers, government ministers are at odds over what to do about it—re-engineer the waterways or restore them to their natural state.
Medical Xpress / Personalized T-cell therapy eliminates detectable metastatic kidney tumor in adolescent after multiple relapses
Researchers and physicians at the Hopp Children's Cancer Center Heidelberg (KiTZ) and other leading cancer centers report an exceptional treatment outcome in an adolescent with an advanced, treatment-resistant kidney tumor. ...
Phys.org / Satellite constellations could create spiraling space debris
To date, close to 30,000 satellites have been launched into Earth's orbit, leading to mounting concerns over the debris created when they collide. In a new analysis posted to the preprint server arXiv, Hugh Lewis of the University ...
Phys.org / Three supermassive black holes discovered in a single galaxy for the first time
An international team of astronomers led by the Max Planck Institute for Extraterrestrial Physics has identified three actively accreting supermassive black holes in the galaxy J0148-4214. Matter is falling into the black ...
Phys.org / African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising ...
Phys.org / Famous oddball quasar isn't X-ray weak after all, astronomers say
For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...
Phys.org / River shipping emits nearly one-quarter of global shipping CO₂, analysis finds
River and canal ships generate roughly a quarter of the world's shipping carbon dioxide emissions, according to new research published in Nature Climate Change. And that's despite the fact that these bodies of water make ...
Medical Xpress / Taking the stairs could cut risk of early death
Taking the stairs could help you live longer—according to new research from the University of East Anglia and the Norfolk and Norwich University Hospital. The study, published today, suggests that climbing stairs significantly ...
