Sitting in a dwarf galaxy about 500 million light years away, supernova iPTF14hls initially seemed like the ordinary explosion of a red giant star when it was discovered by the intermediate Palomar Transient Factory (iPTF) survey in September 2014. Then the brightness of this event lasted more than four times longer than a normal supernova.

Researchers investigating ways to deliver high doses of cancer-killing drugs inside tumors have shown they can use a laser and light-activated gold nanoparticles to remotely trigger the release of approved cancer drugs inside cancer cells in laboratory cultures.

Manufacturers are increasingly using encapsulated coal ash from power plants as a low-cost binding agent in concrete, wallboard, bricks, roofing and other building materials. But a new study by U.S. and Chinese scientists cautions that coal ash from high-uranium deposits in China may be too radioactive for this use.

New research published in Science shows that climate warming reduced the mass of the Cordilleran Ice Sheet by half in as little as 500 years, indicating the Greenland Ice Sheet could have a similar fate.

Of the approximately two dozen medical CT scanners scattered throughout Stanford’s main campus and medical centers, two can be found nestled in basement labs of the Green Earth Sciences Buildings.

North Atlantic right whales – a highly endangered species making modest population gains in the past decade – may be imperiled by warming waters and insufficient international protection, according to a new Cornell analysis published online in Global Change Biology, Oct. 30.

Emissions of sulfur dioxide, an air pollutant produced primarily by burning coal, have fallen by 75 percent in China since 2007, while SO2 emissions in India have jumped 50 percent, according to a new study by researchers at the University of Maryland.

The School of Biological Sciences, Faculty of Science, the University of Hong Kong (HKU), in collaboration with the Institut de Biologie Moléculaire des Plantes (CNRS, Strasbourg, France), has identified a new strategy to simultaneously enhance health-promoting vitamin E by ~6-fold and double both provitamin A and lycopene contents in tomatoes, to significantly boost antioxidant properties.

Worms and clams enhance the release of methane up to eight times more compared to sea bottoms without animals, shows a study by scientists at Stockholm University and Cardiff University.

"You are what you eat" might give way to "you are when you eat," based on a new study tracking shifts in Hawaiian bird abundance, breeding and molting based on climate-related changes to native vegetation.
