New compound stops common complications after intestinal surgery (Links to an external site)

After surgery to remove part of the small intestine in a mouse, normal liver tissue (red) is replaced by scar tissue (yellow-orange), which impairs the organ’s ability to function. The cyan color shows smooth muscle actin, a protein that indicates liver cells’ response to damage. Researchers at WashU Medicine made and tested a compound that […]

AI may predict spread of lung cancer to brain (Links to an external site)

Physicians treating patients with early-stage lung cancer face a conundrum: choosing potentially helpful yet toxic therapies such as chemotherapy, radiation or immunotherapy to knock out the cancer and lessen the risk of it spreading to the brain, or waiting to see if lung surgery alone proves sufficient. When up to 70% of such patients do […]

Neurons help flush waste out of brain during sleep (Links to an external site)

There lies a paradox in sleep. Its apparent tranquility juxtaposes with the brain’s bustling activity. The night is still, but the brain is far from dormant. During sleep, brain cells produce bursts of electrical pulses that cumulate into rhythmic waves – a sign of heightened brain cell function. But why is the brain active when we […]
