A long-term study finds significant changes in brain development linked to anxiety in children with autism. The study, which included brain scans and interviews, also provides new evidence that supports forms of anxiety specific to autism.

Rural counties saw 2.4 times more COVID-19 infections per capita compared to urban counties in July and August of 2021 during a surge of the delta variant, a new study finds. Early data suggest omicron is spreading faster in urban areas but causing more hospitalization and death in rural counties where vaccination is lagging.

The brain's ability to clear a protein closely linked to Alzheimer's disease is tied to our circadian cycle, according to new research. The research underscores the importance of healthy sleep habits in preventing the protein Amyloid-Beta 42 (AB42) from forming clumps in the brain, and opens a path to potential Alzheimer's therapies.

Decades of research has shown that limits on calorie intake by flies, worms, and mice can enhance life span in laboratory conditions. But whether such calorie restriction can do the same for humans remains unclear. Now a new study confirms the health benefits of moderate calorie restrictions in humans -- and identifies a key protein that could be harnessed to extend health in humans.

Tumor cells release telltale molecules into blood, urine, and other bodily fluids. But it can be difficult to detect tumor-derived DNA, RNA, and proteins in the earliest stages of disease, when cancers can be easier to treat and cure. Earlier stages shed fewer cancer cells—and fewer tumor markers.

New research reveals that sex differences in learning and memory mechanisms are triggered by biological events occurring during puberty. Findings show prepubescent female rodents have much better hippocampal long-term potentiation (LTP) and spatial learning than same-age males, but puberty has opposite consequences for synaptic plasticity in the two sexes.

Rapid weight gain in the first and final months of a pregnancy may play a key role in the development of excess fat tissue in children and adolescents -- at least if those children are girls, according to a new study.
Weight gain in pregnancy may be linked to later growth patterns in daughters

Researchers have developed a new protocol for monitoring acute lymphoblastic leukemia (ALL), the most common cancer in children, to inform more effective treatment strategies and detect disease recurrence. The personalized mediator probe PCR (MP PCR) uses multiple genomic cancer cell markers in a single assay and is simpler than current techniques. It improves monitoring clonal tumor evolution to detect a relapse sooner and avoid false negative results.

People who live in rural communities comprise nearly one-fifth of the U.S. population. No single profile encapsulates rurality and health outcomes vary significantly between regions. While all rural residents experience higher rates of all-cause mortality, certain issues are more prevalent within specific racial and ethnic rural populations.
