Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in a coordinated way throughout the body. About a ...

A popular climate theory suggested that melting Antarctic glaciers would release iron into the ocean, sparking algae blooms that pull carbon dioxide from the air. New field data from West Antarctica reveal that meltwater provides far less iron than . ...

Sponges may be ancient, but their timeline has been murky. New research suggests the earliest sponges were soft and skeleton-free, explaining why their fossils don't appear until much later. By analyzing hundreds of genes and modeling how skeletons . ...

Scientists have uncovered a surprising new way that giant embryonic cells divide--without relying on the classic "purse-string" ring long thought essential for splitting a cell in two. Studying zebrafish embryos, researchers found that instead of ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building . ...

Scientists at Texas A&M are turning an everyday pick-me-up into a high-tech medical switch. By combining caffeine with CRISPR gene editing, researchers have created a system that allows cells to be programmed in advance -- and then activated simply . ...

Scientists racing to tackle plastic pollution have created a surprising new contender: a biodegradable packaging film made partly from milk protein. Researchers at Flinders University blended calcium caseinate with starch and natural nanoclay to form ...

Scientists at UC Berkeley have discovered a microbe that bends one of biology's most sacred rules. Instead of treating a specific three-letter DNA code as a clear "stop" signal, this methane-producing archaeon sometimes reads it as a green light- ...

Researchers found that cutting two amino acids common in animal protein--methionine and cysteine--made mice burn significantly more energy. The boost in heat production was nearly as powerful as constant exposure to cold temperatures. The mice didn't ...

Astronomers have spotted what may be one of the universe's earliest barred spiral galaxies -- a striking cosmic structure forming just 2 billion years after the Big Bang. The galaxy, COSMOS-74706, dates back about 11.5 billion years and contains a .. ...
