Ultra-processed foods threaten brain health in kids and teens, review warns

Children, adolescents, and unborn babies exposed to high levels of ultra-processed foods (UPFs) face increased risks of impaired brain development, cognitive deficits, and long-term mental health challenges. The review underscores how UPF-driven changes in reward pathways, nutrient deficits, inflammation, and the gut–brain axis can have lasting impacts across generations.

Oxytocin may protect mood during sleep disruption in women

Oxytocin, often called "the love hormone," may play a protective role in mood disturbances triggered by sleep loss and hormonal shifts during key reproductive transitions like postpartum and menopause, according to a study being presented Saturday at ENDO 2025, the Endocrine Society's annual meeting in San Francisco, Calif.

Melatonin receptor signaling counters sleep fragmentation-mediated infertility in T2DM

This new article publication from Acta Pharmaceutica Sinica B, discusses how melatonin receptor 1a alleviates sleep fragmentation-aggravated testicular injury in T2DM by suppression of TAB1/TAK1 complex through FGFR1.

Slower speech response linked to sleepiness in older adults

A new study led by UCLA investigators shows that Verbal Reaction Time (VRT), the amount of time it takes a person to respond verbally, can be a marker of sleepiness in older adults.

Study spotlights postoperative delirium as a preventable and high-impact complication

A new large-scale study spotlights postoperative delirium as a preventable and high-impact complication, which is driven by patient frailty and surgical stress-and one that can be addressed through low-cost, evidence-based interventions.

MIT develops implantable device to automatically release emergency glucagon

For people with Type 1 diabetes, developing hypoglycemia, or low blood sugar, is an ever-present threat. When glucose levels become extremely low, it creates a life-threatening situation for which the standard treatment of care is injecting a hormone called glucagon.

Why vitamin B6 could raise the risk of hypoglycemia for people with diabetes

A large-scale Mendelian randomization study found no genetic evidence that vitamins A, C, or D reduce the risk of major diabetic complications. However, higher genetically predicted vitamin B6 levels were strongly associated with increased risk of diabetic hypoglycemia, warranting caution with supplementation.
