Scientists map step-by-step activation of brain receptors

When it comes to brain proteins, small changes can make a dramatic difference. Researchers studying NMDA (N-methyl-D-aspartate) receptors, which are essential for learning, memory and moment-by-moment consciousness, know that even slight changes in their activity level can mean the difference between normal function and serious neurological disorders.

How many cities will face unlivable heat by 2100?

Researchers assessed future urban heat exposure and adaptive capacity in 1,563 major cities worldwide, using high-resolution climate projections, local climate zones, and socioeconomic indicators. By 2100, hundreds of millions may live in cities exceeding habitability thresholds, with adaptation gaps greatest in low-income regions.

Skin-to-skin care linked to stronger brain development in preterm infants

Preterm infants born before 32 weeks who received more skin-to-skin contact while in the hospital showed stronger brain development in areas tied to emotion and stress regulation than babies who received less skin-to-skin care, according to a study published in the September 24, 2025, issue of Neurology, the medical journal of the American Academy of Neurology.

Mango shows unexpected benefits for diabetes prevention

If presented with two snacks, one containing seven grams of sugar and another with over 30 grams of sugar, choosing the healthier option should be a no-brainer, correct? Well, maybe not. Less sugar is not automatically healthier.

Reversing age-related vision loss with retinal lipid therapy

Changes in vision are often a common sign of aging. If you sit in a dimly lit restaurant with anyone over the age of 60, you'll likely hear the person say, "Hold on - let me pull out my cell phone. I need more light to read the menu!" But what if we could reverse age-related visual decline?

Study finds 7 to 8 cups a day of coffee, tea, and water tied to longer life

Researchers using UK Biobank data found that drinking 7–8 cups of coffee, tea, and water per day was linked to the lowest mortality risk. The healthiest mix was a 2:3 balance of coffee to tea, with further benefits over water substitution, but excessive intake (>9 cups) raised cardiovascular risk.

How food choices and cooking methods drive brain inflammation and disease

Researchers reviewing evidence in NeuroSci show how dietary AGEs and their interaction with RAGE drive oxidative stress, inflammation, and neurodegeneration. They highlight how cooking methods and diet choices could lower AGE burden and protect brain health, while calling for rigorous clinical trials.
