People who followed the MIND diet more closely showed slower brain shrinkage and less grey matter loss over time, with the strongest differences equivalent to about 2.5 years of delayed brain aging. Berries and poultry were linked with healthier brain changes, while sweets and fried fast foods were associated with greater tissue loss.

More than half of 16,000 apparently healthy adults had signs of atherosclerosis, with arterial plaques already detectable in about 1 in 13 people ages 18 to 29. Researchers say directly imaging the arteries could reveal hidden cardiovascular disease years or even decades before symptoms appear.

What sounds like a jumble of noise is actually a group signal

CONCLUSION: Health literacy is a key factor of active and successful ageing. To promote active ageing, older adults care centres should prioritise health literacy.

Engineered fluids could extract metals from fracked reservoirs, supplying materials for solar cells and electric vehicles

People with depression who dramatically cut ultra-processed foods experienced notable improvements in their symptoms in a small preliminary study. Researchers suspect healthier eating may benefit the brain partly by reducing gut damage and chronic inflammation.

The Alzheimer’s risk gene APOE4 may actively damage brain blood vessels and sabotage the cellular systems that remove harmful proteins. Researchers were able to reverse some of these effects in experiments, revealing promising new targets for Alzheimer’s, Parkinson’s, and other neurodegenerative diseases.

Experimental reactor needed much more uranium and heavy water than the country could muster

A common mistake during blood pressure checks could make readings appear substantially higher than they really are. Johns Hopkins researchers found that leaving the arm unsupported can raise systolic readings by about 6.5 mmHg, potentially affecting a hypertension diagnosis.

Shifts in blood proteins could point to ways to fight menopause “brain fog” and prevent later dementia

Companies striving to reduce continent’s reliance on foreign shots must overcome major financial and logistical challenges

A review of more than 265,000 people found that cannabis use was associated with higher rates of both committing violence and becoming a victim of it. The researchers say the link is significant but does not prove cannabis itself is the cause.
