3D Camera for Your Smartphone
Engineers at MIT have discovered a new way of gathering depth information that could be used to create 3D cameras requiring only the modest processing power of a smartphone.
What's the Latest Development?
By modifying the concept used by Microsoft's Kinect, engineers at MIT have created a device that retrieves depth information more accurately and works under all lighting conditions. It is so small, cheap and efficient that it could be incorporated into cellphones at virtually no extra cost. Using clever algorithms, engineers created a one-pixel camera that can recreate two-dimensional images. To achieve the third dimension, a parametric algorithm was used to map real space onto a flat plane, which better predicts light refraction.
What's the Big Idea?
Kinet works by measuring 'time of flight': "A pulse of infrared laser light is fired at a scene, and the camera measures the time it takes the light to return from objects at different distances." As soon the as technology was released, intended for a new generation of gamers, computer engineers began hacking it. At MIT alone, high-tech tinkerers have created a Minority Report-style interface, a navigation system for small robotic helicopters and a holographic video transmitter.

It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
