Some of medicine's smallest patients can present its biggest imaging challenges. An infant's heart can be as small as a walnut, beating rapidly inside a body that will change dramatically as the child grows. Yet much of the ...

Organs don't just grow in early life; they can change in response to physiological or environmental challenges in adulthood. Researchers have now identified an active role for the intestinal muscles in remodeling the gut ...

For more than 70 years, the drug 6-thioguanine (6-TG) has been used to treat leukemia. Although its clinical effects have been studied extensively, scientists are still uncovering the molecular mechanisms that determine whether ...

Anyone who has run while pushing a stroller knows stroller running can feel cumbersome and hard on the body. But does it increase the risk of injury? According to a new study from researchers at Penn State Berks, the answer ...

Over a decade ago, scientists redefined how to study organ development by generating seemingly unremarkable clumps of cells. They dubbed them organoids: organ-like microstructures produced using stem cells. Stem cells are ...

For decades, neuroscientists have thought about communication between the cerebral cortex and the basal ganglia in a fairly linear way. The cortex sends information into the basal ganglia, where that information is processed ...

Encephalitis is a serious condition in which an infection or autoimmune response triggers inflammation of the brain. The resulting swelling can disrupt normal brain function, causing neurological changes such as confusion, ...

Advances in genome sequencing are giving more families access to prenatal genetic testing and new information about an unborn baby's health, including whether genetic changes may be linked to a neurodevelopmental condition.

As mice age, their total egg reserve collapses around tenfold. Yet, according to a new study published in Nature Aging, the proportion of eggs in the brief window where a follicle is shifting from dormant to growing stays ...
