Light-induced whole-molecule vibration can rupture melanoma cells’ membrane
Rice scientists and collaborators at Texas A&M University and University of Texas MD Anderson Cancer Center have found a new way to kill cancer cells by using near-infrared light to make a small dye molecule attached to their membrane vibrate strongly. It is the first time this kind of mechanical molecular action has…

Neuroscientists discover molecular mechanism that allows memories to form (2020)
Encoding memories in engram cells is controlled by large-scale remodeling of the proteins and DNA that make up cells’ chromatin, according to an MIT study. This chromatin remodeling, which allows specific genes involved in storing memories to become more active, takes place in multiple stages spread out over several…

Georgia Tech, Meta create open dataset to advance solutions for carbon capture
To avoid catastrophic climate impacts, excessive carbon emissions must be addressed. At this point, cutting emissions isn’t enough. Direct air capture, a technology that pulls carbon dioxide out of ambient air, has great potential to help solve the problem.

First space images captured by balloon-borne telescope
Astronomers have successfully launched a balloon-borne telescope that has begun capturing images of the universe on its first flight above the Earth’s atmosphere. The Super Pressure Balloon-Borne Imaging Telescope (SuperBIT) was flown to the edge of space by a helium-filled NASA scientific balloon the size of a…
