After decades of detective work, geneticists have pinpointed the mutation that turns some house-cats into ginger tabbies. A small missing stretch of DNA in a regulatory region near the ARHGAP36 gene on the X chromosome greatly increases the gene’s activity…
Researchers identified regular-firing neurons in the centrolateral amygdala that drive anxiety behaviors. Normalizing GRIK4 gene dosage in basolateral amygdala pyramidal cells reversed anxiety, depression, and social deficits in mice overexpressing the gene, suggesting a targeted treatment approach for anxiety disorders.
Vitamin D may slow cellular aging by preserving telomere length, a new study finds. Learn about the benefits for DNA, proper dosage, and potential risks.
Brain learning involves multiple simultaneous synaptic rules, challenging traditional models New research reveals that the brain does not use a single, uniform learning rule across synapses. Instead, different synapses on the same neuron follow distinct rules, with some adhering to…
Late morning workouts optimize muscle building by balancing hydration, cortisol, and energy levels Muscle growth primarily depends on consistent, progressive strength training rather than the specific time of day. Early morning workouts may be hindered by dehydration, high cortisol levels,…
Affectionate parenting shapes openness, conscientiousness, and agreeableness in adulthood A longitudinal twin study following 2,232 British twins from childhood to age 18 demonstrates that affectionate parenting between ages 5 and 10 predicts higher levels of openness, conscientiousness, and agreeableness in…
Why everyone needs stronger muscles From our 30s onward we gradually lose muscle tissue, a process called sarcopenia. Weaker muscles increase the risks of frailty, falls, loss of independence and even early death. Large cohort studies show that every extra…
A study published in the Journal of Exercise Physiology Online investigated the effects of daily one-repetition maximum (1RM) bench pressing over a 34-day period. Seven physically active participants performed a daily 1RM bench press, followed by five volume sets at…
PP405 hair regrowth treatment from UCLA may help androgenetic alopecia by reactivating dormant hair follicles, but trials and FDA approval are still ongoing.
