Check your DNA with your cellphone

Check your DNA with your cellphoneGenetic testing isn’t something you can do in a few minutes. It’s an involved process, requiring special chemicals and instruments that aren’t commonplace everywhere. But now some scientists at Berkeley have created a technique that uses electrostatic tech instead, which simplifies everything.

The DNA is prepared in a lab first and put on a microarray. Negatively charged microspheres are spread across the surface, which push themselves into clumps as they move away from the like-charged DNA areas. It’s an easier and simpler way as well as less costly than current techniques we use now. Apparently the resulting clumps are large enough to be recorded by simple imaging devices like your cellphone camera. It means that in the near future DNA testing could be super quick and accessible.

USC Lab creates 3-D holographic displays
The ICT Graphics Lab at USC has created a low-cost volumetric 3-D display that brings Princess Leia one step closer to begging Obi-Wan for help. The system projects high-speed video onto a rapidly spinning mirror. As the mirror turns, it reflects a different and accurate image to each potential viewer.

The rendering algorithm can recreate virtual and real scenes with correct occlusion, horizontal and vertical perspective, and shading. Close to 5,000 individual images are reflected every second within the surface area and create a real-space three-dimensional object. Video below.
