Experimental compound helps burn fat without muscle loss
Sun, 23 Aug 2026 06:24:17 EDT

A decades-old compound may point to a new way of treating obesity by making the body burn more energy rather than simply reducing appetite. In mice, TOFA increased energy use by as much as 18%, reduced body fat without significant muscle loss, and improved blood sugar, triglycerides, and fatty liver disease. It also produced stronger results when combined with GLP-1 drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound.

A hidden “on switch” in human DNA has finally been decoded
Sun, 23 Aug 2026 08:14:40 EDT

Researchers have used AI to uncover the DNA signature of a key genetic “switch” involved in turning genes on. After analyzing about 500,000 DNA sequences, the model identified the initiator in roughly 60% of human genes. The breakthrough could help predict the effects of harmful mutations and eventually contribute to decoding the broader genetic instructions that control gene activity throughout the body.

Physicists create a tiny “Big Bang” with surprisingly small atomic nuclei
Sun, 23 Aug 2026 09:08:55 EDT

Researchers at CERN have created microscopic versions of the early Universe by colliding surprisingly small atomic nuclei at nearly the speed of light. The collisions produced quark-gluon plasma, the ultra-hot matter believed to have filled the cosmos shortly after the Big Bang. Even more intriguingly, the particles left behind reveal the shape of the nuclei that created them, offering a new way to probe both nuclear physics and the Universe’s earliest moments.

JWST finds early galaxies may be 4 times more massive than thought
Sat, 22 Aug 2026 08:36:23 EDT

Astronomers using JWST have discovered that massive early galaxies contain far more small, faint stars than expected. That hidden population could make some of these galaxies three to four times more massive than previous estimates. The finding makes it even harder to explain how enormous, mature galaxies formed so soon after the Big Bang. It could also suggest that planets around low-mass stars were more common in the early universe than scientists realized.

This common vitamin was linked to 13% better cognitive scores
Sun, 23 Aug 2026 00:31:43 EDT

Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test than those taking none. The preliminary findings suggest vitamin D could be worth studying as a potentially modifiable factor during an early window of cognitive decline.

Black holes keep tearing these stars apart, but they survive
Sun, 23 Aug 2026 00:08:52 EDT

Astronomers have found stars that repeatedly skim past supermassive black holes, surviving each encounter while producing a new burst of light. In some systems, those flares mysteriously fade with every return. Researchers now think the key may be stars that were already spinning extremely fast before being captured. That rapid rotation could explain both the fading flares and how the stars ended up in such extraordinarily tight black hole orbits.

A major Alzheimer’s risk gene may shrink brain cells years before symptoms
Sun, 23 Aug 2026 11:15:41 EDT

Researchers have uncovered a possible reason why the Alzheimer’s risk gene APOE4 can disrupt the brain long before memory problems begin. In mice, APOE4 increased a protein called Nell2, shrinking neurons and making memory circuits unusually active. That early hyperactivity predicted worse memory later in life. Reducing Nell2 in adult mice reversed the abnormal changes, raising hopes for a new way to intervene before Alzheimer’s progresses.

This shark can live 400 years. Its eyes barely seem to age
Sat, 22 Aug 2026 23:14:26 EDT

Greenland sharks may live for 400 years without suffering the kind of retinal decline normally associated with aging. Researchers found healthy eye tissue and active proteins specially adapted for seeing blue light in the dim Arctic depths. DNA repair mechanisms may help keep their eyes functioning across centuries. The discovery could eventually offer new clues for protecting human vision as we age.

This yeast supplement may boost cancer-fighting immunity
Sat, 22 Aug 2026 06:34:22 EDT

A simple yeast-based food supplement may help restore the immune system’s ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune cells in the bone marrow, leading to stronger, longer-lasting cancer-fighting responses against colorectal, skin, and breast cancer cells.

Multilingual people may have brains up to 13 years younger
Sat, 22 Aug 2026 09:12:23 EDT

People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a stronger effect.
