Alternating from spheres to rugby balls is no longer the sole preserve of mercury isotopes, an international team at CERN's ISOLDE facility reports in a paper published in Physical Review Letters.
The longest partial lunar eclipse in nearly 600 years, which will bathe the Moon in red, will be visible Thursday and Friday for a big slice of humanity.
Remains of a toothless, two-legged dinosaur species that lived some 70 million years ago has been discovered in Brazil, researchers said Thursday, calling it a "very rare" find.
Using novel data sets and computing systems, researchers at the Department of Energy's Oak Ridge National Laboratory are simulating how climate change affects the safety and security of the country. This research can help policy and decision makers at federal, state and local levels quickly identify risk factors and develop real-world mitigation strategies.
Exotic laser-produced high-energy-density (HED) plasmas akin to those found in stars and nuclear explosions could provide insight into events throughout the universe. Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered a new way to measure and understand these plasmas, among the most extreme states of matter ever produced on Earth....
The ancient Maya had stone temples and palaces in the rainforest of Central America, along with dynastic records of royal leaders carved in stone, but they lacked a basic commodity essential to daily life: Salt. The sources of salt are mainly along the coast, including salt flats on the Yucatan coast and brine-boiling along the coast of Belize, where it rains a lot. But how did the inland Maya...
Until recently, B cells—present in the blood stream—were mainly thought to produce antibodies and present antigens to help with the immune response to pathogens. A research team at the Vaccine and Immunotherapy Center (VIC) at Massachusetts General Hospital (MGH) led by Ruxandra Sîrbulescu Ph.D., and Mark Poznansky, MD, Ph.D., is exploring the novel protective roles that B cells may play in...
An international team of engineers and technicians has finished assembling a next-generation satellite that will make the first global survey of Earth's surface water and study fine-scale ocean currents. The Surface Water and Ocean Topography (SWOT) mission is just a year out from launch, and the final set of tests on the spacecraft have started.
The NASA/ESA Hubble Space Telescope has completed its annual grand tour of the outer Solar System. This is the realm of the giant planets—Jupiter, Saturn, Uranus, and Neptune—extending as far as 30 times the distance between Earth and the Sun. Unlike the rocky terrestrial planets like Earth and Mars that huddle close to the Sun's warmth, these far-flung worlds are mostly composed of chilly...
Groundwater in California's Central Valley is at risk of being depleted by pumping too much water during and after droughts, according to a new study in the AGU journal Water Resources Research, an interdisciplinary journal that focuses on hydrology and water resources.
A parasitoid wasp that is the natural enemy of a fly known as the spotted-wing drosophila could be a good friend to growers. Washington State University researchers recently confirmed the discovery of the potentially beneficial wasp in the United States for the first time.
Video footage from NASA's Perseverance Mars rover of the Ingenuity Mars Helicopter's 13th flight on Sept. 4 provides the most detailed look yet of the rotorcraft in action.
An atom's electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic physics is known as the Pauli exclusion principle, and it explains the shell structure of atoms, the diversity of the periodic table of elements, and the stability of the material...
New research by a team of University of Florida investigators, and others, provides evidence that host immunity drives evolution of the dengue virus. The work, published today in Science, retrospectively analyzes two decades of dengue virus genetic variation from Thailand, alongside population-level measures of infection and immunity.
JILA researchers have tricked nature by tuning a dense quantum gas of atoms to make a congested "Fermi sea," thus keeping atoms in a high-energy state, or excited, for about 10% longer than usual by delaying their normal return to the lowest-energy state. The technique might be used to improve quantum communication networks and atomic clocks.
An international team of scientists has found an innovative, animal-friendly manner for studying venom genes. The technique makes it possible to determine the unique venom production of a wide range of venomous animals that have scarcely, if at all, been studied.
Some ancestral rodents likely had repeated infections with SARS-like coronaviruses, leading them to acquire tolerance or resistance to the pathogens, according to new research publishing November 18th in PLOS Computational Biology by Sean King and Mona Singh of Princeton University, US. This raises the possibility that modern rodents may be reservoirs of SARS-like viruses, the researchers say.

Stargazers across all of North America can witness the phenomenon from Thursday night into Friday morningStargazers across North America can expect to be dazzled by a red-hued “beaver” full moon on Thursday night and into Friday morning, during the longest partial lunar eclipse in almost six centuries.Lunar eclipses happen when Earth blocks the sun’s light, which usually illuminates the...
A few short months after the end of a devastating wildfire season, many B.C. communities are cleaning up after disastrous floods. As it turns out, wildfires are well known to boost the risk of severe flooding and...
The International Space Station remains at increased risk from orbiting debris following this week's Russian weapons test, NASA said Thursday.
Joining the global effort to curb air pollution, researchers at Texas A&M University have developed computational tools to accurately assess the footprint of certain organic atmospheric pollutants. Their simulation, described in the journal Environmental Science and Technology, could help government agencies keep a closer check on human-made sources of carbon-based pollutants.
Bubbles are common in nature and can form when ocean waves break and when raindrops impact surfaces. When bubbles burst, they send tiny jets of water and other materials into the air. A new study from the University of Illinois Urbana-Champaign examines how the interplay between bubble surfaces and water that contains organic materials contributes to the transport of aerosolized organic...
