Device can theoretically trap a light ‘bit’ for an infinite amount of time

(Phys.org)-Researchers have designed a nanoscale device that, under ideal conditions, can confine a “bit” of light (that is, light with a single precise energy value) for an infinite amount of time. Although a physically realized device would inevitably lose some of the trapped light due to material imperfections, the researchers expect that it should be possible to completely compensate for this loss by incorporating some form of optical gain like that used in lasers, so that in principle the lifetime can be infinitely large even in a real device.

NASA’s Mars Announcement: Present-day transient flows of briny water on steep slopes

NASA held a press briefing today to publicize a cool incremental result in the story of present-day liquid water on Mars. How big a deal is this story? Was all the pre-announcement hype justified? Is this just NASA discovering water on Mars for the zillionth time? What does this mean for things many space fans care about: life on Mars or future human exploration?

Amyloid plaques in Alzheimer’s and diabetes: Novel leads for inhibitors

When proteins change their structure and clump together, formation of amyloid fibrils and plaques may occur. Such ‘misfolding’ and ‘protein aggregation’ processes damage cells and cause diseases such as Alzheimer’s and type 2 diabetes. A team of scientists from the Technical University of Munich (TUM) headed by Professor Aphrodite Kapurniotu have now developed molecules that suppress protein aggregation and could pave the way for new treatments to combat Alzheimer’s, type 2 diabetes and other cell-degenerative diseases.
