The physics of cloaking

In this seminar, Dr. Greg Gbur presents the current state of research on cloaking devices, the differences between science fiction and what seem to actually be possible, and different applications beyond invisibility, like protection from thermal radiation or earthquakes.

TED talk about femto photography

I already mentioned the camera built by a team in the MIT Media Lab, allowing with its trillions of frame per second, to capture the propagation of light or to see around corners.

TED published a video of the talk given by Ramesh Raskar, where he presents this work and the new possibilities it opens.

Looking Around Corners using Femto-Photography

The MIT Media Lab, that I mentioned previously when they published their experiment consisting in filming the very propagation of light, strikes again by using their device to take pictures of objects hidden from the line of sight.

Update: there is now a TED talk presenting femto photography.
