Researchers generate terahertz laser with laughing gas

>>Device may enable “T-ray vision” and better wireless communication By Jennifer Chu Within the electromagnetic middle ground between microwaves and visible light lies terahertz radiation, and the promise of “T-ray vision.” Terahertz waves have frequencies higher than microwaves and lower than infrared and visible light.

Microparticles could help fight malnutrition

>>New strategy for encapsulating nutrients makes it easier to fortify foods with iron and vitamin A By Anne Trafton About 2 billion people around the world suffer from deficiencies of key micronutrients such as iron and vitamin A. Two million children die from these deficiencies

Flexible yet sturdy robot is designed to “grow” like a plant

>>Its extendable appendage can meander through tight spaces and then lift heavy loads By Jennifer Chu In today’s factories and warehouses, it’s not uncommon to see robots whizzing about, shuttling items or tools from one station to another. For the most part, robots navigate pretty

Nanoparticle orientation offers a way to enhance drug delivery

>>Coating particles with “right-handed” molecules could help them penetrate cancer cells more easily By Anne Trafton MIT engineers have shown that they can enhance the performance of drug-delivery nanoparticles by controlling a trait of chemical structures known as chirality — the “handedness” of the structure.

Technique helps robots find the front door

>>Navigation method may speed up autonomous last-mile delivery By Jennifer Chu In the not too distant future, robots may be dispatched as last-mile delivery vehicles to drop your takeout order, package, or meal-kit subscription at your doorstep — if they can find the door. Standard

Better autonomous “reasoning” at tricky intersections

>>Model alerts driverless cars when it’s safest to merge into traffic at intersections with obstructed views By Rob Matheson MIT and Toyota researchers have designed a new model to help autonomous vehicles determine when it’s safe to merge into traffic at intersections with obstructed views.

Double-sided tape for tissues could replace surgical sutures

>>New adhesive that binds wet surfaces within seconds could be used to heal wounds or implant medical devices By Anne Trafton Inspired by a sticky substance that spiders use to catch their prey, MIT engineers have designed a double-sided tape that can rapidly seal tissues

Two-legged robot mimics human balance while running and jumping

>>New control system may enable humanoid robots to do heavy lifting and other physically demanding tasks By Jennifer Chu Rescuing victims from a burning building, a chemical spill, or any disaster that is inaccessible to human responders could one day be a mission for resilient,

System provides cooling with no electricity

>>Passive device relies on a layer of material that blocks incoming sunlight but lets heat radiate away By David L. Chandler Imagine a device that can sit outside under blazing sunlight on a clear day, and without using any power cool things down by more

Enabling autonomous vehicles to see around corners

>>By sensing tiny changes in shadows, a new system identifies approaching objects that may cause a collision By Rob Matheson To improve the safety of autonomous systems, MIT engineers have developed a system that can sense tiny changes in shadows on the ground to determine
