Practice may do more than make perfect. Researchers found that extensive training physically reorganizes the brain, allowing learned tasks to bypass the prefrontal cortex and run through specialized circuits instead. By freeing the brain's "thinking" center, people became better at performing another task at the same time, challenging the long-held idea that humans only switch rapidly between tasks rather than truly multitask.

Scientists discovered that extreme deep-sea pressure squeezes valuable nutrients out of sinking organic particles, providing an unexpected food source for ocean microbes. The finding could rewrite our understanding of both deep-ocean ecosystems and how carbon is stored on Earth.

Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms better suited to the changing conditions survived and went on to dominate the seas, offering a glimpse of how modern marine life could respond to climate change.

Researchers have recreated the physics of extracting energy from a spinning black hole using a stationary device that produces synthetic ultrafast rotation. The achievement transforms a long-standing theoretical idea into a practical experiment and could inspire new advances in optics, wireless communications, and quantum science.

Researchers found that tau is essential for turning new experiences into lasting memories by helping organize the brain's memory-storing cells. The mouse study also revealed how abnormal tau may contribute to Alzheimer's by disrupting both the formation of new memories and the recall of existing ones.

A simple, non-invasive ultrasound treatment could one day help injured joints heal instead of remaining trapped in a cycle of damaging inflammation. Researchers at The University of Alabama in Huntsville found that continuous low-intensity ultrasound encouraged key immune cells called macrophages to shift from an inflammatory state toward one that supports tissue repair.

“President Donald Trump said on ​Saturday that he had ‘just finished’ a physical at Walter ‌Reed National Military Medical Center, referring to the medical examination he underwent in late May after which the White House said he was ​in excellent health,” Reuters reports. Said Trump: “I just finished a perfect physical at ​Walter Reed, I […]

“Key U.S. weapons stockpiles remain significantly depleted and will come under even more intense pressure if strikes against Iran continue at the current rate, as President Donald Trump reiterated Friday that the ceasefire in the conflict is ‘over,'” CNN reports. “The situation with armaments could impact the American military’s ability to fight a potential future […]

Three decades of loyal clients keep her tethered to a city she can no longer afford to call home.

The city got blamed after buyers pulled out of the deal. But the real mess has always been on the sellers’ side, where no one is truly in charge.

Josh Harris shepherded Trick Dog to international fame. Now he’s betting it all on Quik Dog, a “sports bar inside a family restaurant.”

After taking pitcher Jackson Flora with the No. 4 pick, Buster Posey and the Giants selected Barry Bonds’ nephew, Peyton Bonds, in the third round of the draft.

A karass is “a group of people linked in a cosmically significant manner, even when superficial linkages are not evident.” I think of rss.chat as a social network for my karass. A small group of people, not trying to get famous or rich from using a social network, rather wanted to work with or stay […]
