Being infected with the virus could come with more freedom  A new type of test uses a small blood sample to look for the presence of coronavirus antibodies. In one version of the future, a new type of test that measures antibodies would help restore a sense of normalcy for some people even as the […]



Molecules identified that reverse cellular aging process

May 15th, 2020 at 12:24 am » Comments Off

A new discovery paves the way for novel drugs that could help safeguard DNA and slow the aging process Central to a lot of scientific research into aging are tiny caps on the ends of our chromosomes called telomeres. These protective sequences of DNA grow a little shorter each time a cell divides, but by […]

High-speed microscope captures fleeting brain signals

March 26th, 2020 at 10:50 am » Comments Off

When a neuron fires, calcium flows into the cell in a wave that sweeps along the cell body. Images of this infragranular neuron were obtained three times per second by two-dimensional scanning with a Bessel focus. Redder structures are deeper in the mouse cortex. (UC Berkeley images by Na Ji) Electrical and chemical signals flash […]
