New Imaging System Peers Around Corners

A new imaging system could use opaque walls, doors, or floors as 'mirrors' to gather information about a given scene. The camera produced recognizable 3-D images of a wooden figurine and of foam cutouts outside of the device’s line of sight.

The principle behind the system is essentially that of the...

Lab-on-a-Chip Device Evaluates Efficacy of Malaria Treatments

Spread by mosquitoes, malaria is caused by a tiny parasite that infects human red blood cells. University of British Columbia researcher Hongshen Ma and his team designed a lab-on-a-chip device to better understand the changes in red blood cells caused by Plasmodium falciparum, the...

Question of the Week
Would you enjoy a 'digital detox?'

 A recent event called the "Day of Unplugging" kicked off last week, challenging people to go without their cell phones and technology for 24 hours. The "digital detox" idea encourages everyone to step away from their computers and smartphones. Some people are opposed to the idea and see no need to unplug...

A team of MIT researchers is building cubes or towers that extend solar cells upward in three-dimensional configurations. The results from the structures they’ve tested show power output ranging from...
