As a result, other studies that have examined the cardiovascular effects of space radiation on astronauts have been unable to ...

Every cell in the body has the same DNA, but different cell types—such as muscle or brain cells—use different parts of it.

Understanding how cells turn genes on and off is one of biology's most enduring mysteries. Now, a new technology developed by chemist Brian Liau and his collaborators at Harvard offers an ...

Michael Buck, PhD, professor of biochemistry in the Jacobs School, recently received NIH funding to explore how molecular readers of DNA access and activate seemingly hidden genes.

Scientists uncovered how the amino acid leucine enhances mitochondrial efficiency by preserving crucial proteins that drive ...

New research from Johns Hopkins Medicine shows that the enzyme biliverdin reductase A (BVRA) plays a direct protective role ...

How do stem cells know what to become? Nearly three decades after scientists isolated the first human embryonic stem cells, researchers are still working hard to understand precisely how a single, ...

New research from Johns Hopkins Medicine shows that the enzyme biliverdin reductase A (BVRA) plays a direct protective role against oxidative stress in neurons, independent of its role producing the ...
