Neuroscience Brain scans of 8,783 healthy Canadians aged 35-69 found people eating the most ultra-processed food (chips, soda, sugary cereal, ready meals) were about 40% more likely to have hidden brain damage like silent mini-strokes, even though their memory scores were normal. The link was strongest in women.

Health Plastic isn't as inert as we'd thought: Scientists found that tiny everyday microplastics sitting in plain water spontaneously make reactive oxygen, a damaging chemical that made proteins clump and burst red blood cells in lab tests. The more water-repelling the plastic, the stronger it was.

Health A new long-term study has linked late-night eating with a significantly higher risk of developing cirrhosis and metabolic dysfunction-associated steatotic liver disease (MASLD), possibly because eating out-of-hours disrupts the body's natural circadian rhythms.

Genetics A study of over 12,000 Norwegian families found that by age eight, a child’s ADHD traits come mainly from their own genes, not from how their parents’ genes shape the home. Researchers found no firm evidence that parenting style or the home environment tied to parents’ DNA drives ADHD in their kids.
