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

AI for nanoparticles

>>AI-based method could speed development of specialized nanoparticles A new technique developed by MIT physicists could someday provide a way to custom-design multilayered nanoparticles with desired properties, potentially for use in displays, cloaking systems, or biomedical devices. It may also help physicists tackle a variety

Engineers design color-changing compression bandage

>>Bandage is threaded with photonic fibers that change color to signal pressure level    Compression therapy is a standard form of treatment for patients who suffer from venous ulcers and other conditions in which veins struggle to return blood from the lower extremities. Compression stockings

Chemists synthesize millions of proteins not found in nature

>>New technology could lead to development of novel “xenoprotein” drugs against infectious diseases MIT chemists have devised a way to rapidly synthesize and screen millions of novel proteins that could be used as drugs against Ebola and other viruses. All proteins produced by living cells

Making driverless cars change lanes more like human drivers do

>>Algorithm computes “buffer zones” around autonomous vehicles and reassess them on the fly In the field of self-driving cars, algorithms for controlling lane changes are an important topic of study. But most existing lane-change algorithms have one of two drawbacks: Either they rely on detailed

Albatross robot takes flight

>>Autonomous glider can fly like an albatross, cruise like a sailboat MIT engineers have designed a robotic glider that can skim along the water’s surface, riding the wind like an albatross while also surfing the waves like a sailboat. In regions of high wind, the

Researchers develop virtual-reality testing ground for drones

>>With new system, drones navigate through an empty room, avoiding crashes while “seeing” a virtual world Training drones to fly fast, around even the simplest obstacles, is a crash-prone exercise that can have engineers repairing or replacing vehicles with frustrating regularity. Now MIT engineers have

Plug-and-play diagnostic devices

>>Modular blocks could enable labs around the world to cheaply and easily build their own diagnostics. Researchers at MIT’s Little Devices Lab have developed a set of modular blocks that can be put together in different ways to produce diagnostic devices. These “plug-and-play” devices, which require little
