Material generates steam under solar illumination
A new material structure developed at MIT generates steam by soaking up the sun.
Fiber optic light pipes in the retina do much more than simple image transfer
Self-cooling solar cells boost power, last longer
Scientists may have overcome one of the major hurdles in developing high-efficiency, long-lasting solar cells—keeping them cool, even in the blistering heat of the noonday Sun.
World's largest-ever flying bird identified
Scientists have identified the fossilized remains of an extinct giant bird that could be the biggest flying bird ever found. With an estimated 20-24-foot wingspan, the creature surpassed size estimates based ...
Earth survived near-miss from 2012 solar storm: NASA
Back in 2012, the Sun erupted with a powerful solar storm that just missed the Earth but was big enough to "knock modern civilization back to the 18th century," NASA said.
How do we terraform Venus?
It might be possible to terraform Venus some day, when our technology gets good enough. The challenges for Venus are totally different than for Mars. How will we need to fix Venus?
Artificial spacetime experiment could show tantalizing effects of gravitational waves
Trio of physicists create computer simulation of dark matter using an empirical function
New material puts a twist in light
Scientists at The Australian National University (ANU) have uncovered the secret to twisting light at will. It is the latest step in the development of photonics, the faster, more compact and less carbon-hungry ...
A hotspot for powerful cosmic rays: Physicists a step closer to finding mysterious sources
An observatory run by the University of Utah found a "hotspot" beneath the Big Dipper emitting a disproportionate number of the highest-energy cosmic rays. The discovery moves physics another step toward ...
Superconducting and ferroelectric properties of perovskite
(Phys.org) —Perovskite materials are the newest contender for breaking the silicon ceiling in solar cell technology. But they don't just absorb light. Cambridge researchers have found they emit it like ...
Boosting the force of empty space
Vacuum fluctuations may be among the most counter-intuitive phenomena of quantum physics. Theorists from the Weizmann Institute (Rehovot, Israel) and the Vienna University of Technology propose a way to amplify ...
Facebook under fire over 'creepy' secret study (Update 2)
Facebook secretly manipulated the feelings of 700,000 users to understand "emotional contagion" in a study that prompted anger and forced the social network giant on the defensive.
