Children who start school a year early more likely to be diagnosed with ADHD, study shows

A new study by Harvard Medical School researchers found that children born in August are 30% more likely to receive an ADHD diagnosis compared to their slightly older peers. The study suggests that the earlier school enrollment may lead to improper diagnosis due to normal behavior being perceived as abnormal relative to older classmates.

Great apes and ravens plan without thinking

Researchers have found that great apes and ravens develop planning capacities through associative learning, rather than human-like mental simulations. The new model shows how animals can learn to make decisions that lack immediate benefits but lead to meaningful outcomes in the future.

91 percent response rate for venetoclax against newly diagnosed AML in older adults

A new combination treatment of venetoclax and azacitidine has shown a 91 percent response rate in older adults with newly diagnosed acute myeloid leukemia (AML). The treatment has been associated with no more side effects than the use of azacitidine alone, and patients with IDH mutations have experienced long-lasting responses.

Transfusions with older blood linked to adverse events, death, new study finds

A new study found that transfusions of packed red blood cells stored for 22 days or more are associated with a 5% increase in mortality risk in trauma patients. The study suggests that patients who require massive transfusions may benefit from receiving fresh stored packed red blood cells, or those stored for 14 days or less.

Researchers discover Chinese pyramids exhibit surprising orientation patterns, defying expectations of traditional funerary practices. The study suggests that ancient Chinese emperors intentionally aligned their pyramids to the star Polaris, reflecting a deeper understanding of celestial movements and astronomy.

Increasing staffing levels could reduce cesarean delivery use

A study of 102,236 deliveries in France found that higher staffing levels for obstetricians and midwives were associated with lower cesarean delivery rates. A 10% increase in staff levels was linked to a 2.5% decrease in intrapartum cesarean deliveries and a 3.4% decrease in elective cesarean deliveries.

Baby up at night? Inactivity may be a culprit

Babies who are less active tend to get less sleep overall, according to new Michigan State University research. Infants who slept more at night had better weight-for-length scores and were less active during the day. Parents can promote tummy time and physical activity to help their baby get more sleep.
