Phys.org / The 'Bloom cycle' is a newly described biochemical pathway that explains key plant processes
For decades, the basics of plant growth have been taught in grade school: Plants make their food out of water from the soil, light from the sun and carbon dioxide from the air in a process called photosynthesis. What gets ...
Phys.org / Jackdaw chicks listen to adults to learn about predators
Jackdaw chicks learn about predators by listening to adults, new research shows. Scientists played recordings of predator calls to chicks in their nests—and paired the sounds with either adult jackdaw "alarm" calls or "contact" ...
Phys.org / NASA's MAVEN detects first evidence of lightning-like activity on Mars
While sifting through the extensive data collected by NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic signal commonly caused ...
Medical Xpress / 7 hours 18 mins may be optimal sleep length for avoiding type 2 diabetes precursor
Sleeping for 7 hours and 18 minutes every night may be the sweet spot for warding off the risk of insulin resistance—the precursor to type 2 diabetes—suggests a large observational study published in the open access journal ...
Phys.org / Reduce rust by dumping your wok twice, and other kitchen tips
When you reach the bottom of a container of milk or honey, you might be tempted to tip the container over to get that last pesky little bit out. After all, you only need another teaspoon for that recipe, and you're sure it's ...
Phys.org / Newfound third cell type enables fully functional hair follicles in the lab
Hair regrowth treatment may soon take a major leap forward, as researchers in a recent study have successfully grown complete, fully functional hair follicles outside of the living body, in a dish. This was made possible ...
Dialog / The wetland puzzle that stumped hydrology for decades—how physics and AI joined forces to predict unmeasured regions
For years, the Prairie Pothole Region has bothered me in a very specific way. On a map, it looks like a normal landscape: fields, gentle slopes, small streams. But hydrologically, it behaves like something else entirely. ...
Tech Xplore / Deepfake songs are exploding, but a new tool shuts them down
Artificial intelligence models can now clone a voice with just a few seconds of audio, fueling a surge of deepfake songs online and creating a growing crisis for musicians who don't want their voices hijacked. Beyond the ...
Phys.org / Ancient zircon crystals provide a window into early Earth history
There are many open questions about how our planet formed 4.55 billion years ago: When did plate tectonics start? When did the Earth's mantle begin to vigorously circulate in a process called convection? What was Earth like ...
Phys.org / Tiny Purgatorius fossils in Denver Basin hint at early primate spread southward
New minuscule fossils of Purgatorius, the earliest-known relative of all primates—including humans—have been unearthed in a more southern region of North America than ever before, and the breakthrough is providing paleontologists ...
Phys.org / 70-year field study finds fertilizer imbalance can halve mycorrhizal fungi
Almost all plants live in close symbiosis with so-called mycorrhizal fungi—an important symbiosis for absorbing essential nutrients. In their new study, a team led by ecologist Christina Kaiser from the Center for Microbiology ...
Phys.org / Life forms can planet hop on asteroid debris—and survive
Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new Johns Hopkins University study finds. The work demonstrates that a certain hardy bacterium easily ...
