Improving battery safety and efficiency for electric vehicles

As electric vehicles and personal portable electronics become more ubiquitous, researchers are trying to solve some of the major limitations of current lithium-ion battery technology, which uses a graphite anode and a lithium-based ...

Team develops new tools to help search for life in deep space

Are we alone in the universe? An answer to that age-old question has seemed tantalizingly within reach since the discovery of ice-encrusted moons in our solar system with potentially habitable subsurface oceans. But looking ...

A new method for the fast detection of a key antiviral

Interferons are proteins that constitute an important part of our natural defense systems. These proteins also exhibit a remarkable antiviral activity. The recombinant human interferon α2b (rhIFNα2b) was approved by the ...

Why teapots always drip

The "teapot effect" has been threatening spotless white tablecloths for ages: if a liquid is poured out of a teapot too slowly, then the flow of liquid sometimes does not detach itself from the teapot, finding its way into ...

Capillary

Capillaries ( /ˈkæpɨlɛri/) are the smallest of a body's blood vessels and are parts of the microcirculation. They are only 1 cell thick. These microvessels, measuring 5-10 μm in diameter, connect arterioles and venules, and enable the exchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances between blood and surrounding tissues. During embryological development, new capillaries are formed by vasculogenesis, the process of blood vessel formation occurring by a de novo production of endothelial cells and their formation into vascular tubes. The term angiogenesis denotes the formation of new capillaries from pre-existing blood vessels.
