New approach reveals structure and function of individual synapses

A common analogy used to describe the brain is that it consists of tiny interconnected computers. Each one of these computers, or neurons, process and relay activity from thousands of other neurons, forming complex networks that allow us to perceive our surroundings, make decisions, and guide our actions. Communication between neurons occurs through tiny connections called synapses,

Solving long-sought protein structure opens new avenues for treating disease

Scientists at Sanford Burnham Prebys have identified the long-sought structure of an essential blood protein: vitronectin. Knowing the protein’s structure—an advance that enables rational drug design—could lead to medicines that kill multi-drug-resistant bacteria, halt cancer metastasis, treat age-related macular degeneration (AMD) and more. The study was published in Science Advances.  “For decades, scientists have speculated

Arsenic in drinking water may change heart structure

Drinking water that is contaminated with arsenic may lead to thickening of the heart’s main pumping chamber in young adults, a structural change that increases the risk for future heart problems, according to new research in Circulation: Cardiovascular Imaging, an American Heart Association journal. “People drinking water from private wells, which are not regulated, need

Researchers determine atomic structure of molecular complex associated with birth defects

In a study published today in Science, UT Southwestern and Rockefeller University researchers used advanced microscopes to determine at atomic resolution the structure of a molecular complex implicated in birth defects and several cancers. The Hedgehog signaling pathway, which transmits information to embryonic cells, is crucial to human health. Insufficient signaling during development leads to

Scientists discover hidden structure of enigmatic ‘backwards’ neural connections

For decades, the neuroscience community has been baffled by the existence of dense connections in the brain that seem to be going “backwards.” These connections, which span extensively across distant areas of the neocortex, are clearly conveying important information. But until now, the organization of the connections, and therefore their possible role, was largely unknown.
