Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored light sails as an alternative. ...
New research from the Department of Energy's Oak Ridge National Laboratory, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about controlling heat flow in solid ...
Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge speaks directly to one of ...
Researchers from the University of Nottingham have uncovered a surprising biological quirk in domestic cats that may help explain why they are so prone to chronic kidney disease. Unlike dogs and most other mammals, cats appear ...
Crystals have repeatedly been found at archaeological sites alongside Homo remains. Evidence shows that hominins have been collecting these stones for as long as 780,000 years. Yet, we know that our ancestors did not use ...
An international team of researchers has uncovered a remarkable molecular trick used by a unique group of land plants, one that could eventually be engineered into crops like wheat and rice to dramatically boost how efficiently ...
Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently remains difficult, especially ...
Outdoor air pollution is estimated to contribute to more than 100,000 premature deaths in the United States each year, according to the National Weather Service. Accurate air quality forecasts—designed to protect public ...
By converting plastic waste into a microbe-friendly food source, scientists have built an upcycling pipeline that turns the waste into a variety of useful products. The findings are detailed in the journal Nature Sustainability.
Rural communities bordering the Tongass National Forest harvest more than 4.5 million pounds of wild food per year, including 100 different species that our public lands help support. Just how much food is this? An average ...
