Phys.org / Mars mission ends: NASA declares Maven dead after six months of silence
After six months of radio silence, NASA's Maven spacecraft around Mars has been declared dead.
Medical Xpress / New antibiotic kills drug-resistant bacteria by targeting previously unknown vulnerability
Researchers at McMaster University have discovered a new antibiotic that kills some of the world's most dangerous and drug-resistant bacteria—and does so by targeting a previously unknown vulnerability, opening the door to ...
Phys.org / A giant star may have destroyed itself in one of the universe's rarest explosions
Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving ...
Phys.org / Half-ton early bovines roamed 4-million-year-old grasslands in Europe
The first large-sized bovines grew to up to half a ton 4 million years ago in the European Early Pliocene, an early step toward our modern diversity of large-bodied buffalo and cattle, according to a study published June ...
Phys.org / Temperature gaps help sneeze clouds stay denser and travel farther, experiments show
When a person coughs or sneezes, they expel a cloud of microscopic particles capable of carrying viruses and bacteria that act as vectors for respiratory diseases such as flu, COVID-19 or tuberculosis. Understanding how these ...
Phys.org / Real-time fish interaction enlarges young guppy brains, while screen time falls short
Young guppies who were able to see and interact with live fish developed larger brains than guppies who only saw other fish on a screen. This is shown in a new study from Stockholm University, published in Biology Letters. ...
Phys.org / Water-wave tweezers steer tiny 'surfers' without touching them
Summer brings with it the sight of surfers moving seamlessly across wave crests, with ocean waters carrying them along coastlines. A team of scientists has now created a similar phenomenon—with small objects rather than surfers—that ...
Medical Xpress / Beyond the brain: Organs help shape the nervous systems that control them
A new Yale study reveals that major organ systems in the body aren't just passive structures operating on directions from command central—the brain—but instead are active participants in controlling their own functions.
Phys.org / First deliberately injured Langobard woman in skeletal record reshapes view of male-only violence
The Langobards are frequently depicted as fierce warrior-like people, with all known archaeological evidence of violence restricted to men. However, nearly 1,400 years ago, a Langobard woman took two severe injuries to the ...
Phys.org / Integrating citizen science with experimental data uncovers how switchgrass adapts flowering by region
In its native habitat, switchgrass flowered earlier when growing farther north. In experiments with diverse genetic samples, it flowered earlier in the south.
Tech Xplore / From tough plant waste to everyday products, this light-powered advance opens a path to greener plastics
A pioneering technology capable of converting lignin, one of the world's most abundant organic compounds, into vanillin and biodegradable materials has been unveiled by the University of Alicante (UA), in collaboration with ...
Phys.org / Programmable chemistry unlocks drugs only in target cells, aiming to cut side effects
Potent drugs like chemotherapy can be life-saving, but often with life-threatening side effects. Notably, they can be indiscriminate, killing both cancer cells and healthy cells in one swoop. Increasing a drug's on-target ...
