New research could expand the color palette for glass windows that change color at the flick of an electric switch.
Asteroids may not hit our planet at regular intervals after all. Scientists have reached this conclusion after analyzing impact craters formed in the last 500 million years, concentrating on precisely dated events.
“The evidence is incontrovertible. Global warming is occurring.” “Climate change is real, is serious and has been influenced by anthropogenic activity.” “The scientific evidence is clear: Global climate change caused by human activities is occurring now, and is a growing threat to society.”
Imagine if you could gas up your GM car only at GM gas stations. Or if you had to find a gas station servicing cars made from 2005 to 2012 to fill up your 2011 vehicle. It would be inconvenient and frustrating, right? This is the problem electric vehicle owners face every day when trying to recharge their cars. The industry’s failure, so far, to create a universal charging system demonstrates why setting standards is so important – and so difficult.
Controlled nuclear fusion has been a holy grail for physicists who seek an endless supply of clean energy. Rather than heating atoms to temperatures found inside the sun or smashing them in a collider, say scientists, it might be possible to nudge them close enough to fuse by using shaped laser pulses: ultrashort, tuned bursts of coherent light.
