In the most severely socially impaired males with autism spectrum disorders, researchers found a smaller-than-normal amygdala, an almond-shaped danger-detector deep in the brain. The study suggests that social fear triggers hyperactivity in the amygdala, which eventually leads to toxic adaptation and cell death.
A study of childhood cancer survivors found that their children were more likely to be born early or underweight compared to siblings of cancer-free individuals. The risk was highest for children whose mothers received pelvic radiation as treatment.
A recent study published in Journal of Vision found that judging facial similarity in children can accurately estimate the probability that two children are close genetic relatives. Researchers used participants' ratings to transform into estimates of genetic relatedness.
A study published in PLOS Biology found that zebra finch siblings reared on lower-quality diets showed improved growth rates after switching to a normal diet, but at the cost of impaired learning performance. Compensatory growth, rather than diet quality itself, was linked to poor cognitive ability in adulthood.
A new study reveals that targeted melanoma education of high-risk groups leads to sustained improvements in skin self-examination rates. The intervention, which included personalized educational materials and counseling sessions, significantly increased the number of siblings who performed regular skin self-examinations.
Researchers found that fruit fly species D. sechellia develops a specialized olfactory system to detect the morinda fruit, which is toxic to other species. This unique system involves increased numbers and sensitivity of specific olfactory hairs, suggesting an evolutionary adaptation in just a limited time span.
A recent study by Joanne M. Murabito and colleagues found that having a sibling with cardiovascular disease increases the risk of developing CVD, even after adjusting for traditional risk factors. The research analyzed data from over 4,500 participants and found a 55% increased risk for incident CVD in those with a sibling CVD history.
