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

Protecting confidentiality in genomic studies

>>Cryptographic system could enable “crowdsourced” genomics, with volunteers contributing information to privacy-protected databases. Genome-wide association studies, which look for links between particular genetic variants and incidence of disease, are the basis of much modern biomedical research. But databases of genomic information pose privacy risks. From

Untangling DNA knots

Chemical engineers discover how to control knots that form in DNA molecules CAMBRIDGE, MA — Just like any long polymer chain, DNA tends to form knots. Using technology that allows them to stretch DNA molecules and image the behavior of these knots, MIT researchers have

For nuclear weapons reduction, a way to verify without revealing

>>New isotope-detection method could prove compliance but avoid divulging secrets In past negotiations aimed at reducing the arsenals of the world’s nuclear superpowers, chiefly the U.S. and Russia, a major sticking point has been the verification process: How do you prove that real bombs and

Integrating optical components into existing chip designs

>>Technique would allow addition of optical communication components to existing chips with little modification of their designs Two and a half years ago, a team of researchers led by groups at MIT, the University of California at Berkeley, and Boston University announced a milestone: the fabrication
