Researchers uncover the proteins involved in key communication networks, which could help us better understand conditions like cancer and obesity. Our many different organ systems are in constant communication with each other. During exercise, for example, muscles send out signals to fat and liver tissue to release their energy sources. While these communication networks play a critical role in our bodies every day, it has been historically difficult to uncover such pathways...

Researchers have developed a new moisture-driven electricity generation device made of a thin layer of fabric, sea salt, carbon ink, and a special water-absorbing gel. The device works by keeping one end of the fabric dry, while the other end is perpetually wet. The difference in moisture content of the wet and dry regions of the carbon-coated fabric creates an electric current...

Nothing lasts forever, including the stars in our night sky. One of the brighter and more notable stars in our sky is Betelgeuse, the bright red supergiant in the shoulder of Orion.

In late 2019, astronomers around the world grew giddy with excitement, because we saw this giant star get fainter than we’ve ever seen it before. Since Betelgeuse is at the end stages of its life, there was some speculation this might be a death rattle before the end.

But the cause of the “great dimming” wasn’t ...

Findings open up a potential new avenue for therapies aimed at countering neurodegeneration. Researchers have made a surprising discovery linking Delta/Notch signaling in subperineurial glia (SPG) to the regulation of nerve ensheathment and neurotransmitter release at the Drosophila neuromuscular junction (NMJ). SPG, the counterpart of the endothelial layer in the vertebrate blood-brain barrier, form the key cellular layer that is critical for axonal ensheathment and the blood-brain barrier in Drosophila. The results provide a mechanistic insight into the biology of barrier function and glia-neuron interactions.

While the role of the blood-brain barrier has long been appreciated for its ability to maintain precise control over what molecules can enter the nervous system, very littl...
