The offline Jedi chapter focuses on sharpening themselves and helping the community.

For many Parkinson’s disease patients, depression is the hardest part. A new Yale study may finally explain why standard antidepressants aren’t effective.

Yale scientists have found that cells compute their size using membrane signaling waves, revealing a new insight into biological information processing.

“The skin is really the first line of defense between any external insults like UV radiation or pathogens. We need our skin barrier to prevent dehydration. An organism is going to do whatever it can to keep those functions intact.”

A new Yale study reveals that your blood vessels operate as a coordinated signaling network—and uncovers the consequences of disrupting that network.

Human skin is constantly rebuilding itself. Every few weeks, the outermost layers shed and are replaced by new cells pushed up from the base. For decades, scientists believed this renewal depended heavily on fibroblasts, a class of supportive cells nestled in the deeper layer of the skin that secrete growth-promoting molecules and build the structural scaffolding that holds tissue together.

The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have known about this signaling for decades. What they didn't know, until now, is that it follows a remarkably organized pattern, one that persists across days and weeks, governed by a network of cells that have, in a sense, assigned themselves permanent roles.

A Yale study reveals, for the first time, the brain signals that determine whether we're conscious of our own actions—and what happens when those signals break

For Blumenfeld, the multiple signals reflect something fundamental. “Consciousness is so important that it makes sense in evolutionary terms that there's going to be redundancy. Many things are influencing how aware or unaware we are of what we do.”
