A hungry star is eating its cosmic twin at a rate never seen before

A greedy white dwarf star not far from Earth is devouring its closest celestial companion at a rate never seen before, space scientists have discovered. Their study found the double star, named V Sagittae, is burning unusually ...

In a study in mice, researchers have identified genes associated with the dramatic transformation of the mammary gland in pregnancy, breastfeeding, and after breastfeeding as it returns to its resting state.

Artificial intelligence is now part of our daily lives, with the subsequent pressing need for larger, more complex models. However, the demand for ever-increasing power and computing capacity is rising faster than the performance ...

Warmer weather across the globe is reshaping the landscape of human health. A case in point is dengue fever, a mosquito-borne disease once confined largely to the tropics, which often brings flu-like symptoms, and without ...

At the height of the COVID-19 pandemic, players flocked to Axie Infinity, a blockchain-based video game where users received cryptocurrency tokens for their time spent playing. In 2022, when the broader crypto market crashed ...

A Mediterranean-style diet, rich in fiber, vegetable proteins and healthy fats, benefits maternal health during pregnancy and breastfeeding. In addition to improving intestinal function and mucosal immunity, it also prevents ...

From health monitors and smartwatches to foldable phones and portable solar panels, demand for flexible electronics is growing rapidly. But the durability of those devices—their ability to stand up to thousands of folds, ...

A person will have Alzheimer's years before ever knowing it. The disorienting erasure of memories, language, thoughts—in essence, all that makes up one's unique sense of self—is the final act of this enigmatic disease ...

Cell memory can act more like a dimmer dial than an on/off switch

When cells are healthy, we don't expect them to suddenly change cell types. A skin cell on your hand won't naturally morph into a brain cell, and vice versa. That's thanks to epigenetic memory, which enables the expression ...

It was long thought that fat in the brain played no role in neurodegenerative diseases, but Purdue University researchers are challenging that assumption.

Orange rivers signal toxic shift in Arctic wilderness

In Alaska's Brooks Range, rivers once clear enough to drink now run orange and hazy with toxic metals. As warming thaws formerly frozen ground, it sets off a chemical chain reaction that is poisoning fish and wreaking havoc ...

Biomineralization: How sponges form their calcite spicules

Many corals and sponges form skeletons that support and shape their bodies. Whereas biomineralization—the formation of these skeletons—has been intensively studied in corals, the main ecosystem engineers of today's hyperdiverse ...

How harmful bacteria hijack crops

Aphids, grasshoppers and other bugs aren't the only pests that can quickly wipe out a crop. Many harmful bacteria have evolved ways to bypass a plant's defenses. A once-healthy tomato plant can quickly turn sick and blotchy, ...

Creating a top-tier, high-density tungsten single atom catalyst

Designing a catalyst is incredibly difficult—yet researchers at Tohoku University have successfully created a catalyst that is ranked as one of the best. Their catalyst greatly speeds up the oxygen evolution reaction (OER), ...

France's racial blind spot exposed in new study

A groundbreaking new study from The University of Manchester has challenged traditional ideas of race and national identity in France, revealing how French citizens of Indian descent are navigating their identities in a society ...
