Medical Xpress / Quantitative imaging of beta cell mass may help with treatment for type 1 diabetes

In type 1 diabetes, the immune system starts to destroy insulin-producing beta cells in the pancreas. Progressive loss of these cells destabilizes the body's glucose levels and drives the course of the disease, so preserving ...

Phys.org / Artificial kinetochores take the pressure off aging chromosomes during meiosis

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes becomes more prone to ...

Phys.org / Fluid simulation at unprecedented scale provides toolkit for fundamental physics and applied fluid engineering

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at which a fluid filled ...

Phys.org / Photonic 'ski jumps' efficiently beam light into free space

Photonic chips use light to process data instead of electricity, enabling faster communication speeds and greater bandwidth. Most of that light typically stays on the chip, trapped in optical wires, and is difficult to transmit ...

Medical Xpress / Experimental chemo drug triggers 'viral mimicry' signals that rally immune attack

In recent years, scientists have discovered that some chemotherapy drugs not only kill cancer cells directly, but at least in some patients, mysteriously also trigger their immune system to attack the cancer. That would seem ...
