In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant — like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use [...]

Children whose mothers abused methamphetamine (meth) during pregnancy show brain abnormalities that may be more severe than that of children exposed to alcohol prenatally, according to a new study. While researchers have long known that drug abuse during pregnancy can alter fetal brain development, this finding shows the potential impact of meth. Identifying vulnerable brain [...]
Seventy percent of healthy professional and collegiate hockey players had abnormal hip and pelvis MRIs (magnetic resonance imaging), even though they had no symptoms of injury, according to a new study. The study’s surprising findings could serve as a warning for surgeons to not depend excessively on imaging when diagnosing patients.
