Catastrophically warm predictions are more plausible than previously thought, say climate scientists
What will the future climate be like? Scientists around the world are studying climate change, putting together models of the Earth's system and large observational datasets in the hopes of understanding—and predicting over the next 100 years—the.....»»
Scientists accelerate uranium beam with record power
Scientists and engineers at the Facility for Rare Isotope Beams (FRIB) have reached a new milestone in isotope studies. They accelerated a high-power beam of uranium ions and delivered a record 10.4 kilowatts of continuous beam power to a target. The.....»»
Study shows neonicotinoids are harmful to birds on all fronts
Neonicotinoids are widely used insecticides in agriculture and horticulture. However, neonicotinoids usage is highly contentious because of their unintended harmful effects on various types of organisms......»»
Animal social interactions could speed up evolution
Scientists typically predict how species evolve by looking at their genes and the environment they live in, but new research from the University of Aberdeen has highlighted a key factor that's often overlooked: social interactions, where the genes of.....»»
Scientists recreate sound of Earth"s magnetic flip 41,000 years ago
Approximately 41,000 years ago, Earth's magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth's magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed.....»»
How the "social cost of carbon" measurement can hide economic inequalities and mask climate suffering
The social cost of carbon (SCC) is an essential tool for climate decision-making around the world. SCC is essentially a large cost-benefit calculation that helps policymakers compare the benefits of reducing carbon dioxide (CO2) emissions to the soci.....»»
World"s highest-voltage gun accelerates electrons from zero to 80% the speed of light
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed and tested the world's highest voltage polarized electron gun, a key piece of technology needed for building the world's first fully polarized Electron-I.....»»
Declines in plant resilience threaten carbon storage in the Arctic
Rapid warming has impacted the northern ecosystem so significantly that scientists are concerned the region's vegetation is losing the ability to recover from climate shocks, suggests a new study......»»
Scientists explore whether smaller chromosomes lead to more segregation errors during egg cell division
Three RIKEN researchers have shed light on the cellular mechanisms underlying chromosomal abnormalities that can cause miscarriages and congenital disorders such as Down syndrome......»»
Scientists track and analyze lofted embers that cause spot fires
In the chaos of a wildfire, heat, wind, flames and fuel interact to produce embers that are lofted into surrounding areas, starting new spot fires and spreading destruction and property loss in California's wildland-urban interface......»»
Theoretical study demonstrates existence of giant photocaloric effects in ferroelectric perovskites
Solid-state cooling is a promising alternative cooling technique that does not rely on the use of gases or liquids, like conventional refrigeration systems, but instead utilizes the properties of solid materials to refrigerate. This alternative cooli.....»»
A sharper view of the Milky Way with Gaia and machine learning
A group of scientists led by the Leibniz Institute for Astrophysics Potsdam (AIP) and the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) have used a novel machine learning model to process data for 217 million stars observed by t.....»»
Researchers discover new isotope plutonium-227
A research team led by researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has synthesized a new plutonium isotope, plutonium-227. Their study is published in Physical Review C......»»
Mazda hits hybrid high gear as CEO Masahiro Moro teases new electrified technologies
CEO Masahiro Moro says Mazda is developing a new full-hybrid drivetrain in-house as the company launches hybrid versions of its CX-80 crossover, the fourth product riding on the Japanese carmaker's large-vehicle platform......»»
Hurricane Milton Shows How a Storm’s Category Doesn’t Tell the Full Story
Milton’s reclassification to a Category 3 storm suggests it is weakening, but the scale accounts only for wind speed and not hurricane size, storm surge heights, or rainfall—which are all catastrophically large......»»
Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
Hubble and New Horizons offer dual perspectives on Uranus to inform exoplanet research
NASA's Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different viewpoints. The results inform future plans to study l.....»»
Scientists long urged NASA to search for signs of life near Jupiter; now it"s happening
In 2015, Bill Nye was on Marine One with President Obama......»»
Octopus suckers inspire new tech for gripping objects underwater
New adhesive system could be powerful tool for underwater salvage, rescue operations. Over the last few years, Virginia Tech scientists have been looking to the octopus for inspir.....»»
Polar jet stream could reveal Saturn"s rotational period
A hexagon-shaped atmospheric phenomenon first spotted on Saturn by Voyager 1 and Voyager 2 has intrigued scientists since the 1980s. More recently, NASA's Cassini mission has periodically observed the hexagon and its embedded strong eastward jet that.....»»
