880 Scientists remove “zombie” cells and reverse liver damage in mice

ScienceDaily
ScienceDaily · 04/16/2026 07:59 EDT

A rogue set of “zombie” immune cells may be driving aging and fatty liver disease by flooding tissues with inflammation. Researchers found these cells accumulate with age and high cholesterol—and can make up most of the liver’s immune cells in older mice. When scientists removed them, liver damage was dramatically reversed, even without diet changes.

Samsung reportedly forced to raise prices due to ever-rising RAM cost

Up until now, most smartphone manufacturers, Apple and Samsung included, were able to absorb the memory chip price shock through optimizations and cutting costs elsewhere. However, this might not be possible for Samsung going forward. According to a report from Greece, Samsung is planning to raise prices on some of its phones in Europe starting in June. The Galaxy S series and the Galaxy Z Fold7 and Z Flip7 price... Read more

Scientists have discovered that a topical anti-aging drug called ABT-263 can dramatically improve wound healing in older skin. The treatment works by removing damaged “senescent” cells that accumulate with age and slow the body’s repair process. In aged mice, wounds healed much faster after treatment, while the drug also activated genes tied to collagen production and tissue regeneration. Read more

Scientists have uncovered an astonishing new chapter in humpback whale migration: two whales were found to have traveled between breeding grounds in Australia and Brazil, crossing more than 14,000 kilometers of open ocean. One whale shattered records by covering at least 15,100 kilometers between sightings, marking the longest confirmed journey ever documented for an individual humpback whale. Read more

Low vitamin D levels could be quietly making breast cancer surgery recovery far more painful. In a new study, patients deficient in vitamin D were three times more likely to experience moderate to severe pain after mastectomy surgery and ended up using significantly more opioid medication to cope. Researchers say vitamin D may help regulate how the body processes pain through its effects on inflammation and the immune system. Read more

Why did T. rex have such tiny arms? Scientists now think it’s because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators hunting enormous prey. In other words, once the bite became deadly enough, the arms may have stopped mattering. Read more

Scientists in Australia are using cutting-edge DNA techniques to help save one of the world’s rarest marsupials — the critically endangered Gilbert’s potoroo, with fewer than 150 left in the wild. By analyzing tiny traces of DNA in the animals’ scat, researchers uncovered clues about the elusive fungi the potoroos depend on for survival. The findings could help conservationists identify safer new habitats and establish backup populations before disasters like... Read more

For decades, scientists believed ancient humans avoided dense rainforests, treating them as nearly impossible environments for early survival. But a groundbreaking discovery in West Africa is rewriting that story. Researchers uncovered evidence that humans were living deep within rainforest environments in present-day Côte d'Ivoire around 150,000 years ago — far earlier than anyone thought possible. Read more

Scientists have identified the oldest known human remains in Northern Britain as a young girl who lived around 11,000 years ago. Found in a Cumbrian cave and nicknamed the “Ossick Lass,” she was likely between 2.5 and 3.5 years old when she died. Nearby jewelry and evidence of multiple burials suggest the cave held deep spiritual importance for some of Britain’s earliest hunter-gatherers. The discovery is shedding new light on... Read more

Researchers have developed a light-driven method for creating tiny, high-energy “housane” molecules that are valuable for drug development and materials science. These compact ring-shaped structures are difficult to produce because of the intense internal strain they contain. By using photocatalysis and carefully tuning the starting molecules, the team managed to guide the reaction into a clean and efficient pathway. Read more

Scientists in Canada have discovered that ancient underground rocks are naturally producing hydrogen gas — and lots of it. Measurements from mine boreholes in Ontario show the gas can flow continuously for years, offering a potential new source of clean energy called “white hydrogen.” Researchers say this hidden resource could help power industries and remote communities while cutting carbon emissions and reducing dependence on fossil fuels.
