Factors linked to chikungunya, dengue outbreaks discovered

Living at high altitude appears to protect against diabetes, and scientists have finally discovered the reason. When oxygen levels drop, red blood cells switch into a new metabolic mode and absorb large amounts of glucose from the blood.

The scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons.

Researchers have discovered a way to help aging intestines heal themselves using CAR T-cell therapy. By targeting senescent cells that build up over time, the treatment boosted gut regeneration, reduced inflammation, and improved nutrient absorption in mice.

Scientists discovered that vitamin C from food travels through the bloodstream into every layer of the skin, boosting collagen and skin renewal.

Alzheimer's has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain's energy supply help drive the disease, and restoring that balance can reverse damage, even in advanced cases.

Scientists have discovered new anti-ageing compounds produced by a little-studied blood bacterium, opening up promising avenues for future skin-rejuvenation therapies.

Scientists discovered that more muscle and less hidden abdominal fat are linked to a younger biological brain age.

Researchers discovered that raising the protein Sox9 can help the brain's astrocytes clear out toxic plaque buildup linked to Alzheimer's.

Scientists discovered that tiny messengers released by fat tissue, called extracellular vesicles, can carry harmful signals that accelerate the buildup of amyloid-b plaques in the brain.

An international team of scientists has now discovered that people gain more weight on an ultra-processed diet compared to a minimally processed diet, even when they eat the same number of calories.
