Observations detect frequent extreme superflares on the nova V2487 Oph
Astronomers from Louisiana State University (LSU) and College of Charleston have performed photometric observations of a recurrent nova known as V2487 Oph. The observational campaign identified superflares on this source occurring almost daily. The f.....»»
Merging nuclear physics experiments and astronomical observations to advance equation-of-state research
For most stars, neutron stars and black holes are their final resting places. When a supergiant star runs out of fuel, it expands and then rapidly collapses on itself. This act creates a neutron star—an object denser than our sun crammed into a spa.....»»
Technical trials for easing the (cosmological) tension
Thanks to the dizzying growth of cosmic observations and measurement tools and some new advancements (primarily the "discovery" of what we call dark matter and dark energy) all against the backdrop of General Relativity, the early 2000s were a time w.....»»
Warming of Antarctic deep-sea waters contribute to sea level rise in North Atlantic, study finds
Analysis of mooring observations and hydrographic data suggest the Atlantic Meridional Overturning Circulation deep water limb in the North Atlantic has weakened. Two decades of continual observations provide a greater understanding of the Earth's cl.....»»
Unraveling the mysteries of consecutive atmospheric river events
In California's 2022-2023 winter season, the state faced nine atmospheric rivers (ARs) that led to extreme flooding, landslides, and power outages—the longest duration of continuous AR conditions in the past 70 years. Scientists at Lawrence Berkele.....»»
Hubble discovers over 1,000 new asteroids thanks to photobombing
Astronomers have used 19 years' worth of Hubble data to detect over 1,000 previously unknown asteroids in our solar system......»»
Researcher studies worst western US megadrought in 1,200 years
Drylands in the western United States are currently in the grips of a 23-year "megadrought," and one West Virginia University researcher is working to gain a better understanding of this extreme climate event......»»
Researchers train a bank of AI models to identify memory formation signals in the brain
An international research collaboration between Vanderbilt University and the Madrid-based de la Prida lab in the Cajal Institute led to the development of AI models that detect and analyze hippocampal ripples, which are considered biomarkers of memo.....»»
Weather and climate extremes in 2023 impacting the globe with emerging features
Globally, last year was the warmest for thousands of years, with a globally averaged temperature of at least 1.45°C greater than pre-industrial times. The year also saw an unprecedented string of extreme weather and climate events in many parts of t.....»»
How a calcium-sensing protein multitasks
The calcium-sensing receptor is critical for maintaining healthy calcium levels, but CaSR is also well-known for its side hustles. The receptor is increasingly recognized for its ability to detect other ions and proteins and for its role in breast ca.....»»
Electronic tongue can detect white wine spoilage before humans can
While the electronic tongue bears little physical resemblance to its namesake, the strand-like sensory probes of the "e-tongue" still outperformed human senses when detecting contaminated wine in a recent study......»»
Scientists navigate the paradox of extreme cold events in a warming world
According to Copernicus Climate Change Service, February 2024 was the warmest February ever recorded globally......»»
Saturn"s ocean moon Enceladus could support life—researchers are working out how to detect extraterrestrial cells there
Saturn has 146 confirmed moons—more than any other planet in the solar system—but one called Enceladus stands out. It appears to have the ingredients for life......»»
James Webb Space Telescope data pinpoint possible aurorae on a cold brown dwarf
Using new observations from the James Webb Space Telescope (JWST), astronomers have discovered methane emission on a brown dwarf, an unexpected finding for such a cold and isolated world. Published in the journal Nature, the findings suggest that thi.....»»
Tijuana River among most endangered in America due to sewage crisis
The Tijuana River, with frequent flows of sewage and chemical-tainted waters, is among America's top endangered rivers, according to a report that spotlights threats to clean water nationwide......»»
Astronomers discover the most metal-poor extreme helium star
Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that EC 19529–4430 is the most metal deficient among the.....»»
NASA observations find what helps heat roots of "moss" on sun
Did you know the sun has moss? Due to its resemblance to the earthly plants, scientists have named a small-scale, bright, patchy structure made of plasma in the solar atmosphere "moss." This moss, which was first identified in 1999 by NASA's TRACE mi.....»»
Research suggests that part of India will become a climate hotspot
The Indian subcontinent is likely to experience an increasing number of extreme weather events in future. The fertile and densely populated plain around the Indus and Ganges rivers is therefore likely to become a climate change hotspot, which could h.....»»
New radar analysis method can improve winter river safety
University of Alaska Fairbanks researchers have developed a way to use radar to detect open water zones and other changes in Alaska's frozen rivers in the early winter. The approach can be automated to provide current hazard maps and is applicable ac.....»»
Hydrogen recombination found to be most plausible explanation for high levels of energy in stellar superflares
Although their primary purpose is to look for exoplanets, observatories like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) have supplied a vast amount of data on stellar flares, detected with high-precision photometr.....»»
Extreme heat is a problem in Virginia: Researchers want to help
The summers in Hampton Roads, Va., are hot, but for some residents, swelling temperatures and their impacts can be disproportionately worse......»»
