For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an electron—into an exquisitely controlled quantum state.
There are an estimated 10 quintillion insects alive on Earth at any given time. That's 10,000,000,000,000,000,000 individual insects. But how many species are there, why do we need them, and what would happen if their numbers continued to fall? Dr. Alex Dittrich, a zoologist at Nottingham Trent University, explains why these small creatures play such a big role in keeping our planet functioning.
For the first time, scientists can make quantum measurements on a positron particle
New research led by the University of Michigan provides utilities and policymakers with forecasts that can help them better prepare for future extremes in peak energy demand in the United States.
Marine heat waves are usually seen as destructive events that can disrupt entire ocean ecosystems and trigger massive environmental damage. In 2018 and 2019, an extreme heat wave hit the Bering Sea, causing spring sea ice levels to plummet.
This year’s photomicrography contest captured the wonders of the very small, from flying ink droplets to the most adorable jumping spider you've ever seen.
A massive study of more than 460,000 Americans found that ultra-processed foods were not associated with increased colorectal cancer risk overall, challenging a widely held assumption. While processed meat was linked to higher cancer incidence, ultra-processed whole grains and dairy products were associated with lower incidence.
Scientists have uncovered an unexpected danger lurking inside cells: too much RNA can damage the structures responsible for producing energy. A new study found that excess RNA, including the normally essential messenger RNA (mRNA), can directly disrupt mitochondria without relying on the immune system. The discovery could help explain how viral infections and certain aging-related diseases damage cells.
Scientists have cracked a 178-year-old mystery surrounding a train delayed by a solar storm, revealing that the famous incident happened in 1848 rather than 1841. The discovery rewrites the early history of space weather and highlights a threat that still endangers modern power grids, satellites, and communication systems.
A new study tracking 13 astronauts suggests that the human heart may be surprisingly well equipped for a journey to Mars, especially with regular exercise during spaceflight. Researchers found that astronauts' hearts adapted to months of weightlessness and handled simulated Martian gravity without major problems, offering new hope for future missions to the Red Planet.
Scientists have turned blood cells from an 80-year-old into neural stem cells with a molecular age of less than 20, effectively reversing more than 60 years of cellular aging in the laboratory. The discovery offers a new way to investigate how cells become younger and could help researchers better understand age-related diseases such as Alzheimer's.
Astronomers have discovered the lightest known pair of neutron stars — two ultradense stellar remnants that circle each other every 2 hours, 22 minutes, veering toward an inevitable collision about 82 million years from now. By timing radio pulses from one of the stars, the researchers detected three subtle effects predicted by Albert Einstein's general theory of relativity and found that the theory describes the pair's motion to within about 1% — proving the visionary physicist right yet again. The researchers published their findings Sept. 15 in the journal Physical Review Letters.Neutron stars are the collapsed cores of massive stars that exploded as supernovas. Each packs more mass than ...
