Four-legged robot simulates human motion
Four-legged, all-terrain robot can maintain its balance over rugged terrain while carrying a payload of up to 340 pounds; robot can also cope with man-made obstacles and gallop (well, something between “gallop” and “canter”) over impediments

New generator for wind turbines
To connect to the National Grid, large turbines often use a doubly fed induction generator (DFIG) system comprising brushes and slip rings; these require regular maintenance which can be difficult to carry out, particularly offshore or in poor weather conditions; U.K. researchers offer solution

Breakthrough: Dramatic increase in thermoelectric efficiency achieved
Two hundred years ago scientists discovered the thermoelectric effect: Certain materials can convert heat into electricity and vice versa; trouble is, most materials which conduct electricity also conduct heat, so their temperature equalizes quickly; until now: Boston College, MIT researchers solve this vexing problem

Ambient blue light resets tired workers' body clocks
Tedious work during the “wrong” hours of the body’s biological clock — think truckers who drive through the night, or security officers monitoring CCTV screens during the graveyard shift — often leads to drowsiness; falling asleep behind the wheel or in front of a security monitoring screen can lead to catastrophes; researchers develop a way to “fool” the brain to think it is morning

UCSD researchers develop tiny explosive sensor
Sensor works by monitoring the variability of electrical conductivity through thin films of metal phthalocyanines; “The detection capability of this tiny electronic sensor is comparable to current instruments, which are large, bulky and cost thousands of dollars each,” says William Trogler, UCSD professor of chemistry and biochemistry

The long view
Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
