CMU’s 2019 Impact-a-Thon Showcases Light Solutions for Darkness

Camps and villages that are off the grid become more hazardous and tough to work at night without any light source. The 2019 Rothberg Catalyzer Impact-a-Thon at Carnegie Mellon University challenged student teams to develop lighting solutions for requisite areas, independent of electrical power grids.

Elementary Mathematics Brings Star Trek's Holodeck Closer to Reality

For many years we have been hearing that holographic technology is one step closer to realizing Star Trek's famous Holodeck, a virtual reality stage that simulates any object in 3D as if they are real. Sadly, 3D holographic projection has never been realized.

Researchers Discover How Light Stimulates Brain Activity

Optogenetics uses light to regulate brain processes. It is based on light-regulated proteins such as channelrhodopsin-2, an ion channel that opens when it is uncovered to light, thus triggering cellular processes.
