A new national study finds that lesbian, gay, and bisexual (LGB) youth are twice as likely to report trouble falling or staying asleep than their straight peers. This is attributed to greater depression, stress, and family conflict among LGB youth, which can make it harder for them to get a good night's sleep.

The study focuses on KLF8, a protein important for brain function that has been recorded as deficient in patients with Alzheimer's.
Researchers found that children perceive time differently than adults, with a shift in bias around age 7. Children tend to overestimate the duration of an eventful video and underestimate that of an uneventful one, while adults exhibit the opposite bias. This switch is unexpected based on biological models of time perception.
A long-term study by UC Davis MIND Institute researchers identified three distinct paths of intellectual development in autistic children: persistent intellectual disability, an increase in IQ, or average IQ. The study used IQ trajectories to track changes in communication and behavioral development over time.

A healthy diet during pregnancy supports child's neurodevelopment, while higher maternal body fat percentage is associated with weaker cognitive and motor skills.
A new study shows that preschoolers as young as 3-5 years old understand that some reasons for reneging are more defensible than others. Children agree that breaking promises is generally wrong, but are more understanding when good excuses are given. The children's responses revealed that lame excuses are just as bad as none at all.
A new study suggests that hormone replacement therapy (HRT) could help prevent Alzheimer's disease in women who are carriers of the APOE4 gene. The research found that HRT use is associated with improved memory and larger brain volumes among at-risk women. Early introduction of HRT during perimenopause may be particularly beneficial.
