Phys.org / Safer space travel: Scientists create a cosmic ray simulator
Cosmic rays are one of the greatest challenges for space travel and pose a considerable risk to humans and materials. For the first time on European soil, an international research team in collaboration with the European ...
Phys.org / How changes on the Y chromosome may make species reproductively incompatible
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males first, with hybrid males frequently failing to produce functional sperm even when hybrid females ...
Medical Xpress / Enhancing gut-brain communication reverses cognitive decline and improves memory formation in aging mice
Although we've all experienced the sensation of "eating" with our eyes and noses before food meets mouth, much less is known about the information superhighway, known as the vagus nerve, that sends signals in the opposite ...
Medical Xpress / Here's why you might want to clean your headphones
Whether it's enjoying a podcast, listening to music or chatting on the phone, many of us spend hours a day using our headphones. One 2017 study of 4,185 Australians showed they used headphones on average 47–88 hours a month.
Phys.org / Cell death's 'beautiful' rings have implications for biological resilience and immunity
Researchers at the University of Michigan have revealed that cells use a previously unknown feat of molecular craftsmanship to help protect their larger host organisms. The building blocks required for this work are found ...
Phys.org / Bird losses are accelerating across North America, particularly in farming regions where agriculture is most intensive
Since the 1970s, the U.S. has lost billions of birds. We now know that those losses aren't just growing—they are accelerating in places with intensive human activity, particularly where agriculture and expanding communities ...
Medical Xpress / Study maps three biological routes for gastric cancer beyond H. pylori
A study in Gut shows that gastric cancer is shaped by complex interactions between environmental exposure, microbes, host, and tumor biology. The findings reveal distinct cancer routes and targets linked to prognosis and ...
Phys.org / Multi-wavelength observations track bright gamma-ray blazar's three-year cycle
By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a multiwavelength study of a bright gamma-ray blazar known as S5 1044+71. The new study, published Feb. ...
Phys.org / Fish stocks are on the line: Climate change impacts global fishing yields
As the saying goes, there are plenty more fish in the sea—but climate change is rapidly challenging that notion, with fish stocks around the world under threat. New modeling from Monash University predicts how climate change ...
Phys.org / Unexpected magnetic response in gold and silver atomic contacts contradicts previous theoretical predictions
Researchers from the Department of Physics and the University Institute of Materials at the University of Alicante (UA) and the Low Temperature and High Magnetic Field Laboratory at the Autonomous University of Madrid (UAM) ...
Phys.org / How flexible protein regions retain their function via motifs and chemical context
A new LMU study shows how proteins function reliably even without a stable 3D structure—and the crucial importance not only of short sequence motifs, but also of chemical characteristics.
Phys.org / Inside the light: How invisible electric fields drive device luminescence
Fleeting electron-hole pairs are giving scientists a new window into optimizing light-emitting devices (LEDs). Using quantum magnetic resonance, Osaka Metropolitan University researchers have discovered how shifting internal ...
