In a large study of socially inactive older adults, using a computer for up to 2.4 hours per day was linked to a lower risk of developing dementia, but using it more than that increased the risk. This suggests that moderate computer use might be good for brain health, but too much screen time could be harmful, especially for people with limited social activity.

A systematic review found that when a partner responds to a person’s chronic pain with too much help (solicitous) or with criticism (punishing), it is linked to worse pain outcomes like greater disability. This highlights how a partner’s reaction can significantly impact the pain experience, pointing to the need for couples-based interventions in chronic pain management.

A long-term study of over 3,200 people with multiple sclerosis found that higher levels of physical activity at the time of diagnosis were associated with a significantly reduced risk of disability progression over 15 years. This provides strong evidence that staying active is not just safe but may be a powerful way to slow down the disease and improve long-term outcomes for people with MS.

A new study reports on a rare but serious case where a breastfeeding infant, who was a carrier for a metabolic disorder, suffered a life-threatening metabolic crisis after the mother ate unripe ackee fruit. This case shows that toxins from food can pass through breast milk and cause severe illness in genetically vulnerable infants, highlighting a critical need for awareness and dietary counseling for new mothers.

Researchers have developed a new machine learning tool that uses the patterns of kappa and lambda light chains—proteins made by immune cells—to help detect B-cell lymphomas from flow cytometry data. This approach could make diagnosing these cancers faster, more objective, and less dependent on a specialist’s interpretation, potentially leading to earlier and more accurate diagnoses.
