Decarbonizing US electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A generator-level model suggests that most fossil fuel power plants could complete normal lifespans and still close by 2035 because so many facilities are nearing the end of their operational lives.
Scientists have discovered a chemical that kills coho salmon in urban streams before the fish can spawn.
Restoration of vision in blind people through a brain implant is on the verge of becoming reality. Recent discoveries show that newly developed high-resolution implants in the visual cortex make it possible to recognize artificially induced shapes and percepts.
Biologists found single-celled organisms living in sediments 1180 meters beneath the ocean at temperatures of 120 degrees Celsius.
Scientists have helped produce a brand-new, three-dimensional survey of our galaxy, allowing them to peer into the inner structure and observe its star-forming processes in unprecedented detail.
One Friday evening in 1992, a meteorite ended a more than 150 million-mile journey by smashing into the trunk of a red Chevrolet Malibu in Peekskill, New York. Nearly 30 years later, a new analysis of that same Peekskill meteorite and 17 others has led to a new hypothesis about how asteroids formed during the early years of the solar system.
A small group of volcanic islands in Alaska's Aleutian chain might be part of a single, undiscovered giant volcano, say scientists. If the researchers' suspicions are correct, the newfound volcanic caldera would belong to the same category of volcanoes as the Yellowstone Caldera and other volcanoes that have had super-eruptions with severe global consequences.
The Voyager spacecraft continue to make discoveries even as they travel through interstellar space. In a new study, physicists report on the Voyagers' detection of cosmic ray electrons associated with eruptions from the sun -- more than 14 billion miles away.
On 3 December 2020 an international team of astronomers will announce the most detailed ever catalogue of the stars in a huge swathe of our Milky Way galaxy. The measurements of stellar position and movement are in the third data release from the European Space Agency's Gaia space observatory.
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a new study concludes. The study may help resolve what's known as the faint young sun paradox - a lingering key question in Mars science.
Researchers at Harvard Medical School have successfully reversed age-related vision loss in animals as well as eye damage stemming from with a condition mimicking human glaucoma, a leading cause of blindness around the world.
The tree of cortical cell types provides one of the most detailed and complete characterizations of the diversity of neural types in the brain so far.
Researchers have developed a way for a material to store energy in its skin through invertible domes.
Astronomers developed a new method to calibrate detectors to the light from dust in our Galaxy, thereby describing a new physics, with 99.2 percent accuracy, that may show parity symmetry breaking.
A research team has shed new night on the massive star and its neutron star companion, which are thought to be at the core of the gamma-ray binary system LS 5039.
Researchers have identified host proteins and pathways in lung cells whose levels change upon infection by the SARS-CoV-2, providing insights into disease pathology and new therapeutic targets to block COVID-19.
A tiny new silicon-based lab-on-chip test could pave the way for cheap handheld infectious disease testing.
Research introduces temporary adhesives that don't require tearing or ripping to pull apart.
