Clock Stars: Astrocytes Keep Time for Brain, Behavior

Star-shaped cells called astrocytes, long considered boring, “support cells,” are finally coming into their own. To everyone’s surprise they even play an important role in the body’s master clock, which schedules everything from the release of hormones to the onset of sleepiness.

Nanoparticle Paves the Way for New Triple Negative Breast Cancer Drug

A potential new drug to tackle the highly aggressive ‘triple negative’ breast cancer – and a nanoparticle to deliver it directly into the cancer cells – has been developed by UK researchers.

Hydrophobic Proteins on Virus Surfaces Can Help Purify Vaccines

Through experimental and computational tests, new research expands on the theory of virus surface hydrophobicity. By being slightly water-repellant, the outer layers of proteins in virus capsids affect how it interacts with cells and the environment. Understanding this more can improve vaccine production and virus detection.

Scientists Get Closer Look at Living Nerve Synapses

SynapseKlyachko.jpg

The brain hosts an extraordinarily complex network of interconnected nerve cells that are constantly exchanging electrical and chemical signals at speeds difficult to comprehend. Now, scientists at Washington University School of Medicine in St. Louis report they have been able to achieve — with a custom-built microscope — the closest view yet of living nerve synapses.

Surprising Culprit in Nerve Cell Damage Identified

In new research, scientists at Washington University School of Medicine in St. Louis have implicated a specific molecule in the self-destruction of axons, the wiring of the nervous system. Understanding just how that damage occurs may help researchers find a way to halt it.

Are Dialysis Patients Being Over-Screened for Colon Cancer?

• Colonoscopies are being performed more often on healthier dialysis patients than on those with more limited life expectancies; however, overall, dialysis patients are being screened at a much higher rate relative to their life expectancy than their counterparts without kidney failure.
