For as long as I can remember, I've wanted to travel through space. There was only one problem...I get motion sickness from rolling over in bed. So, I opted to keep my feet on the ground. However, for those who can stomach zero gravity, NASA wants to keep such hardy ones healthy. So the agency awarded the University of Michigan Medical School's Center for Biologic Nanotechnology a $2 million grant to develop nanosensors—nano-scale devices that travel inside astronauts' white blood cells. These sensors will detect early signs of damage from radiation or infection. Created from synthetic polymers called dendrimers, the devices are fabricated layer-by-layer into spheres with a diameter of less than five nanometers. Because the sensors are so small, they easily pass through membranes into white blood cells called lymphocytes, where they can detect the first signs of biochemical changes from radiation. To identify cell damage, researchers also plan to develop a retinal-scanning device—a laser capable of detecting fluorescence from infected lymphocytes as they pass one-by-one through narrow capillaries in the back of the eye.

Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
