From a serene view of planet Earth, through the heart of the Milky Way and out to far-flung galaxies, take an armchair tour of the Universe with these dazzling images
The dream of using hydrogen gas as a clean fuel, on a large scale, just got a little bit closer. Chemists have developed a new molecule that can drive chemical reactions to store and release hydrogen under mild temperatures and pressures. No harmful emissions are released when hydrogen is burned; only water and energy are…
The Hubble Space Telescope has captured images of three odd galaxies that may help scientists solve a 13 billion-year cosmic mystery. The galaxies are so old and faint that astronomers nicknamed them “ghost galaxies” in a description. The objects are among the smallest and faintest galaxies near our own Milky Way galaxy, researchers said. “These…
A trio of recent studies faults a common family of corn pesticides for disorienting honeybees, potentially leading to colony collapse disorder. The German chemical company Bayer, which manufactures the pesticides, disagrees.
The task of finding the genetic roots of common disease seems much harder, dimming the promise of personal genomics and the chances of quick medical payoffs from the human genome project, given new data about the human genome in two reports published online in the journal Science. It now appears that large numbers of very…
This spring the World Health Organization (WHO) celebrated the early completion the 2015 development goal of bringing improved drinking water to an additional two billion people since 1990. The feat was a landmark in securing what the U.N. General Assembly declared in 2010 was a universal human right: “access to safe and clean water.” In…
When a killer seaweed touches a kind of spiky coral, the coral pushes a chemical panic button that brings small resident fish to the rescue. Unchecked, seaweed algae can overrun a coral reef, as the community dwindles in “a descent into slime,” says marine ecologist Mark Hay of the Georgia Institute of Technology in Atlanta….
