Sweden reverses decision to phase out nuclear power

X-ray free-electron lasers (XFELs) produce higher-power laser pulses over a broader range of energies compared with most other x-ray sources. Although the pulse durations currently available are enormously ...

Radioactivity as a result of the Chernobyl nuclear power plant disaster in the 1980s is still present in the environment. But 17 national emergency management organisations and 33 research institutes have ...

The road has gotten bumpier for electric cars, with Coda Automotive, one of what had been a promising crop of electric car startups, filing for bankruptcy protection this month.

(AP)—Signs are growing that the sustained surge in cyberattacks emanating from China is imperiling its relations with the U.S., lending urgency to fledgling efforts by both governments to engage on the ...

With over 800 mini-hydroelectric plants awaiting approval in Switzerland, the biodiversity of Swiss river ecosystems could be at stake. More enlightened policies could help preserve the environment.

Offshore wind could provide abundant electricity—but as with solar energy, this power supply can be intermittent and unpredictable. But a new approach from researchers at MIT could mitigate that problem, ...

Buildings can be air-conditioned using entirely natural means, without mechanical ventilation systems. This is the claim made by 78-year-old Benjamin Bronsema, who will be awarded his PhD for his thesis on the subject at ...

(Phys.org) —Grant Schmitz, eyes inches from a 6.5-by-12-foot panel of ultra-high performance concrete, studied the smooth surface for tiny cracks. He and other research engineers carefully marked every ...
