Phys.org / Webb redefines the dividing line between planets and stars
Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.
Phys.org / After 9,000 years of cultivation, rice has reached its thermal limit
Rice has historically been a heat-loving plant. In fact, the wild ancestor of cultivated rice once grew primarily on the sweltering, rain-swept Malay and Indochina peninsulas as well as the islands of Southeast Asia. It wasn't ...
Phys.org / Ph.D. student solves persistent problem in high-entropy alloys
The University of Wyoming's Lauren Kim has solved a persistent problem in the cutting-edge field of high-entropy alloys, a class of materials with great potential in modern engineering, electronics and energy applications—such ...
Phys.org / Andean volcanic eruptions during the Late Miocene likely drove global cooling
Mark Clementz, a professor in the University of Wyoming Department of Geology and Geophysics, and colleagues have produced a compelling study that shows that an increase in volcanic activity in the Andes in the Late Miocene ...
Phys.org / Ancient graves and DNA uncover family bonds that went beyond genetics
You probably have a member of your family that you're not related to by blood—a step-parent, an adopted cousin, your mom's best friend who you grew up calling your aunt. They're indisputably part of your family, but a DNA ...
Phys.org / Discovery of Addison's disease gene in dogs could help humans as well
Among dog breeds, Nova Scotia duck tolling retrievers (tollers) have an unusually high rate of Addison's disease, a condition in which the adrenal glands do not produce enough hormones, notably cortisol and aldosterone. In ...
Phys.org / High school student designs low-cost teabags to remove arsenic from water and help millions
Arsenic contamination in drinking water is a global issue, with over 200 million people estimated to be at risk. While water treatment plants remove the metal, the problem persists in low-resource areas or undertreated well ...
Phys.org / Toothy snout recasts Australia's famed Muttaburrasaurus as a picky eater
In a surprising new study, Australia's most famous plant-eating dinosaur has been described as a "picky eater with a nose for good food" when it roamed across the continent around 96 million years ago. After examining different ...
Phys.org / Information from starquakes provides theoretical evidence for 'fossilized' magnetism in stars
For the first time, new theoretical models, published in Astronomy & Astrophysics, connect the magnetism at the surface of long-dead stellar remnants (white dwarfs) with recent evidence of magnetism at the cores of their ...
Phys.org / Fluorescent technique reveals hidden scale of microfiber pollution from our clothes
Pollution released from our textiles is smaller and more irregular in shape than previously thought, according to new research led by The University of Manchester. In a study published in Scientific Reports, Manchester researchers—in ...
Phys.org / Using computed tomography to study DNA from ancient humans without destroying samples
Research on ancient DNA is surging, but how can scientists ensure that human remains of irreplaceable significance are preserved? This is the question investigated by an international research team led by the University of ...
Phys.org / Shredded stars reveal how black holes ignite trillion-sun flares
Supermassive black holes are among the most enigmatic objects in the universe. They typically weigh millions or even billions of times the mass of the sun and sit at the centers of most large galaxies. At the heart of the ...
