Shingles vaccine linked to 24% lower dementia risk

Older adults who received a shingles vaccine after entering a skilled nursing facility were less likely to be diagnosed with dementia over the following four years, according to a new study. Researchers found that vaccinated adults had a 24% lower risk of dementia compared with those who did not receive…

Supercharged “natural killer” cells could be a powerful new cancer weapon

Cell therapies that harness the immune system have transformed treatment for some cancers of the blood and lymphatic system. Solid tumors, however, have remained much more difficult to treat because they are harder for immune cells to enter and can release signals that weaken nearby immune defenses. Researchers at Stanford…

A Manhattan-sized ice island just broke free from Greenland

Europe’s Copernicus Sentinel-1 mission has documented a major change at Petermann Glacier in northwest Greenland, where a 76 sq km section of the glacier’s floating ice tongue broke away on August 4, 2026. The break represents Petermann Glacier’s largest loss of floating ice since 2012 and the biggest calving event…

Atomic catalyst unlocks the hidden value of plant waste

Lignin gives plants much of their structural strength and represents the largest renewable source of aromatic chemicals found in nature. It can make up a substantial share (up to 35%) of waste biomass from agriculture and forestry. Yet lignin’s complicated molecular structure makes it notoriously difficult to break apart efficiently,…

Scientists find hidden “highways” guiding animal evolution

A human, an octopus, and a coral may appear to have almost nothing in common, but their chromosomes still contain recognizable fragments inherited from an animal ancestor that lived more than 600 million years ago. Researchers at the University of Vienna have now traced how those ancient genomic pieces were…

NASA finds Earth microbes could survive on the Moon

NASA scientists say some microbes carried into space by human explorers may be able to survive in sheltered, shadowed areas near the Moon’s South Pole. The findings, published on Aug. 19, 2026, in Science Advances, underscore the importance of understanding how long Earth microbes can persist in extreme lunar environments.…

Depression may shut down the brain’s ability to make new neurons

Most of the brain’s roughly 100 billion neurons are produced before birth. However, the small number of new neurons that continue to form in the adult hippocampus may play an important role in protecting against depression, according to new research from Columbia University Vagelos College of Physicians and Surgeons. The…

People who live past 110 have an unusual abundance of killer immune cells

People who live to exceptionally old ages may retain an immune system that continues adapting to new threats. Researchers have found that supercentenarians, people who reach age 110 or older, carry unusually high levels of specialized immune cells called CD4 cytotoxic T lymphocytes (CD4 CTLs). These cells have previously been…

Newton’s 300-year-old law just passed its biggest test yet

Gravity is best known as the force that pulls objects toward Earth, but its role extends far beyond falling apples. Across the universe, gravity acts as an invisible framework that influences how galaxies, galaxy clusters, and the largest cosmic structures form and evolve. For decades, however, astronomers have faced observations…
