19+ hour, 21+ min ago   (797+ words) Much of the ancient carbon released from thawing Arctic permafrost appears to end up trapped in seabed sediments rather than quickly returning to the atmosphere. The Arctic’s frozen ground holds an enormous reservoir of organic carbon. As permafrost thaws and…...

19+ hour, 55+ min ago   (832+ words) Some proteins that vanished millions of years ago may still have something to teach scientists about fighting modern infections. University of Oregon biologists have reconstructed antimicrobial molecules dating back as far as 160 million years, and laboratory tests showed that some…...

1+ day, 19+ hour ago   (417+ words) Physicists have uncovered an in-plane Hall response that overturns a century-old assumption about how this famous electrical effect works. The discovery could eventually make multidirectional magnetic sensing possible with one tiny device....

2+ day, 3+ hour ago   (509+ words) A mysterious signal deep underground may offer LUX-ZEPLIN its most intriguing clue to dark matter yet. For nearly a century, scientists have been trying to identify dark matter, the mysterious material believed to account for about 85% of all matter in…...

2+ day, 23+ hour ago   (1147+ words) Beneath cancer’s genetic chaos, tumor cells may be confined to just a handful of recurring states, revealing a simpler path to treatment. Cancer is often defined by its complexity: countless mutations, shifting cell populations, and tumors that evolve under pressure....

3+ day, 18+ hour ago   (429+ words) New findings raise questions about the role of microbes living in the lungs. More than 35 trillion bacteria live throughout the human body, forming microbiomes in the gut, mouth, lungs, skin, and urogenital tract. Researchers increasingly recognize that these microbial communities…...

3+ day, 23+ hour ago   (763+ words) Ancient meteorite minerals reveal a surprisingly strong magnetic field from the solar system’s first 200,000 years. About 4.6 billion years ago, before the Sun and planets existed in their familiar forms, the solar system was a vast cloud of gas and dust....

3+ day, 23+ hour ago   (608+ words) Chang’e-6 samples suggest the Moon’s two very different sides may have formed when uneven heating drove magma from one hemisphere to the other. The Moon presents two dramatically different faces. Its Earth-facing hemisphere is rich in dark volcanic plains, while…...

4+ day, 22+ hour ago   (356+ words) An unusual immune signature in lung cancer has led researchers toward a potential therapy involving tumor microbes and MAIT cells. Bacteria living inside lung tumors may be doing more than simply occupying the tumor environment. In preclinical research from the…...
