A recent study suggests that fewer than half of parents of children with intellectual and developmental disabilities have made long-term care plans. This leaves family members facing a crisis when the parent or primary caregiver is no longer able to provide care, potentially leading to institutionalization.
Research by Kieron Barclay and Mikko Myrskylä found that birth order differences in university subject choice explain half of the gap in siblings' long-term earnings. Later-borns tend to pursue less prestigious subjects like arts, journalism, and teaching.
A new study by Alex Jensen reveals that younger siblings experience a stronger impact from family favoritism compared to older siblings. The research found that when children perceive favoritism, their relationship with parents is strengthened if they feel like the favorite and the parents agree, but weakened if they don't.
A new Iowa State University study found that midlife depression is associated with tension in relationships with mothers and siblings, similar to those with spouses. The research also shows a stronger predictor of depression for daughters than sons, highlighting the importance of considering whole family dynamics.
A review of studies suggests infants with autism siblings have less advanced linguistic and motor skills, detectable from 12 months. Differences in language skills were larger than those in motor skills until they were 3 years old.
A new mathematical method identifies ancient genetic variations contributing to autism spectrum disorder, suggesting a small effect of each variant. The approach uses discordant siblings to find a clear signal of these shared variants, which are common among individuals with autism in both affected and unaffected populations.
Tadpoles are highly attracted to adult frogs and try to mount them to escape their siblings. The study's findings have implications for understanding begging behaviors in poison frogs and parent-offspring conflicts in amphibians.

The study analyzed Swedish birth registry data, comparing siblings discordant for labor induction, and found no increased risk of ASDs among offspring born via induced labor.
A large study found no association between induced labor and increased risk of autism spectrum disorders in children. The research suggests that concern about autism risk should not factor into clinical decisions about inducing labor.
Having a first-degree relative hospitalized with confirmed staph infection significantly increases the risk for microbiologically confirmed Staphylococcus aureus bacteremia. The risk is higher if the infected patient is a sibling than a parent, according to researchers who analyzed data from Denmark.
Researchers found that Mormon communities' unique blend of education, mentorship, and economic support enables individuals with large families to achieve higher education levels. The study suggests that when community resources are in place, the traditional theory of resource dilution is mitigated.
Research suggests that children of older mothers are healthier, taller, and more educated than those born to younger mothers. Despite the risks associated with advanced maternal age, the benefits of delaying childbearing may outweigh these risks due to improvements in public health and social conditions over time.
