Unlike moderate-intensity workouts, which led to a small loss of lean muscle, HIIT preserved it while also improving body composition around the waist.

Scientists found that taking vitamin D2 can actually lower the body's levels of vitamin D3, the form naturally produced by sunlight and more effective at boosting overall vitamin D. Previous studies also suggest that vitamin D3 may provide stronger immune protection against viruses and bacteria.

Researchers traced the increased risk not to ketones, but to the way intestinal stem cells processed the diet’s high levels of fat. That fat-burning activity pushed the cells to multiply more rapidly, potentially raising the chance of cancerous changes. Mon, 05 Oct 2026 21:18:45 EDT https://www.sciencedaily.com/releases/2026/10/261002080037.htm https://www.sciencedaily.com/releases/2026/10/261002080020.htm Scientists have identified an enzyme that may act as a natural defense against the worsening of fatty liver disease, which affects an estimated 100 million Americans. The enzyme, called UBE2N, helps liver cells clear away damaged mitochondria and break down fat, potentially preventing the inflammation, scarring, and cell damage associated with the more dangerous condition MASH.

In lumbar spinal stenosis, these cells become unusually active and may drive the ligament overgrowth that squeezes spinal nerves and causes pain, numbness, and difficulty walking. Researchers found that reducing calcium signaling stopped this abnormal growth in mice.

Boosting this pathway in people reduced inflammation-related immune changes and sped up pain relief, pointing toward potential new treatments for chronic inflammatory diseases.

But for patients with borderline or intermediate risk, the scans could make a meaningful difference by revealing who is actually more likely to develop heart disease.

Researchers say the finding could open the door to lower-oxalate diets or microbiome treatments tailored specifically to people with IBD.

The findings suggest that keeping bedrooms darker could be an overlooked strategy for protecting the heart.

Researchers say closer medication reviews, pharmacist involvement, and automated alerts could help prevent these potentially harmful prescribing cascades.

The finding overturns the idea that damaged areas of the heart are completely incapable of regeneration. Scientists now hope to identify ways to dramatically boost this natural repair process, potentially opening a new path toward treatments for heart failure.

In mice, a single dose controlled cancer and extended survival while avoiding a dangerous complication associated with donor-derived T-cell therapies.

Using ultracold atoms, researchers split an atom’s quantum wave so that one part was held in place while the other fell freely under gravity, then reunited the two to measure the tiny difference that emerged.
