Chip upgrade helps miniature drones navigate

>>Low-power design will allow devices as small as a honeybee to determine their location while flying Researchers at MIT, who last year designed a tiny computer chip tailored to help honeybee-sized drones navigate, have now shrunk their chip design even further, in both size and power consumption.

Faster analysis of medical images

>>Algorithm makes the process of comparing 3-D scans up to 1,000 times faster Medical image registration is a common technique that involves overlaying two images, such as magnetic resonance imaging (MRI) scans, to compare and analyze anatomical differences in great detail. If a patient has

Checking China’s pollution by satellite

>>Study finds reduction in sulfur emissions from power plants Air pollution has smothered China’s cities in recent decades. In response, the Chinese government has implemented measures to clean up its skies. But are those policies effective? Now an innovative study co-authored by an MIT scholar

New system recovers fresh water from power plants

>>Technology captures water evaporating from cooling towers; prototype to be installed on MIT’s Central Utility Plant About 39 percent of all the fresh water withdrawn from rivers, lakes, and reservoirs in the U.S. is earmarked for the cooling needs of electric power plants that use

Keeping data fresh for wireless networks

>>Algorithm provides networks with the most current information available while avoiding data congestion For wireless networks that share time-sensitive information on the fly, it’s not enough to transmit data quickly. That data also need to be fresh. Consider the many sensors in your car. While

Novel transmitter protects wireless data from hackers

>>Device uses ultrafast “frequency hopping” and data encryption to protect signals from being intercepted and jammed. Today, more than 8 billion devices are connected around the world, forming an “internet of things” that includes medical devices, wearables, vehicles, and smart household and city technologies. By

Wireless system can power devices inside the body

>>New technology could enable remote control of drug delivery, sensing, and other medical applications. MIT researchers, working with scientists from Brigham and Women’s Hospital, have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be
