Robert J. Johnston, a biologist at The Johns Hopkins University, studying how cells randomly choose their fates during development and Andrew J. Holland, a molecular biologist at the university’s School of Medicine, whose work focuses on how dividing cells create the correct number of centrosomes, have been named Pew scholars for their promising work in the area of health sciences.

An existing anti-seizure drug improves memory and brain function in adults with a form of cognitive impairment that often leads to full-blown Alzheimer’s disease, according to a study led by neuroscientist Michela Gallagher of The Johns Hopkins University. The findings raise the possibility that doctors will someday be able to use the drug, levetiracetam, already approved for use in epilepsy patients, to slow the abnormal loss of brain function in some aging patients before their condition becomes Alzheimer’s.
In the today’s online issue of Current Biology, a Johns Hopkins team led by neuroscientists Ed Connor and Kechen Zhang describes what appears to be the next step in understanding how the brain compresses visual information down to the essentials. They found that cells in area “V4”, a midlevel stage in the primate brain’s object vision pathway, are highly selective for image regions containing acute curvature. Experiments by doctoral student Eric Carlson showed that V4 cells are very responsive to sharply curved or angled edges, and much less responsive to flat edges or shallow curves.
