'Hidden biological link' among autism genes revealed in study

A new study of autism risk genes by UC San Francisco and UC Berkeley scientists implicates disruption in prenatal neurogenesis—a process in which specialized "progenitor" cells give rise to new brain cells—in the development ...

Critical flaw found in lab models of the human blood-brain barrier

Cells used to study the human blood brain barrier in the lab aren't what they seem, throwing nearly a decade's worth of research into question, a new study from scientists at Columbia University Vagelos College of Physicians ...

A protein that can melt tumors

For the second time, cancer researchers at Vanderbilt have discovered a protein that—when genetically manipulated to impede it from interacting with a gene responsible for cancer genesis—effectively melts tumors in days.

A rift in the retina may help repair the optic nerve

In experiments in mouse tissues and human cells, Johns Hopkins Medicine researchers say they have found that removing a membrane that lines the back of the eye may improve the success rate for regrowing nerve cells damaged ...

A new strategy for making blood stem cells healthier

The hematopoietic (blood-forming) stem cells (HSCs) residing in our bone marrow produce all of our blood cells, including key immune cells that protect us from bacteria and viruses. As we age, our HSCs become less efficient ...

Scientists paint multi-color atlas of the brain

The human brain contains approximately 86 billion neurons, or nerve cells, woven together by an estimated 100 trillion connections, or synapses. Each cell has a role that helps us to move muscles, process our environment, ...
