Tidal heating could make exomoons much more habitable (and detectable)
Within the solar system, most of our astrobiological research is aimed at Mars, which is considered to be the next-most habitable body beyond Earth. However, future efforts are aimed at exploring icy satellites in the outer solar system that could al.....»»
New extended and faint tidal tail discovered
By analyzing the data from the Dark Energy Camera Legacy Survey (DECaLS), astronomers have discovered a new tidal tail likely associated with the galaxy NGC 3785. The newly detected tidal tail is extremely extended and faint. The finding was reported.....»»
Mars may have been habitable much more recently than thought
Evidence suggests Mars could very well have been teeming with life billions of years ago. Now cold, dry, and stripped of what was once a potentially protective magnetic field, the red planet is a kind of forensic scene for scientists investigating wh.....»»
Innovative model offers new way for astronomers to analyze powerful space explosions
Astrophysical explosions are, to give a few examples, driven by the collapse of the iron core of a massive star (known as a core-collapse supernova), the consumption of spaghettified stellar remains by a massive black hole (known as a tidal disruptio.....»»
New gold nanorod technology can fry bacteria to sterilize implants
In the fight against antibiotic resistance, a new technology developed at Chalmers University of Technology, in Sweden, can be of great importance when, for example, hip and knee implants are surgically inserted. By heating up small nanorods of gold.....»»
For heating plasma in fusion devices, researchers unravel how electrons respond to neutral beam injection
Heating a plasma for fusion research requires megawatts of power. One approach that research tokamaks use to achieve the necessary power input is neutral beam injection (NBI). With NBI, fast neutral particles are generated in a device called a beam s.....»»
Millions in the US may rely on groundwater contaminated with PFAS for drinking water supplies
Approximately 71 to 95 million people in the Lower 48 states—more than 20% of the country's population—may rely on groundwater that contains detectable concentrations of per- and polyfluoroalkyl substances, also known as PFAS, for their drinking.....»»
Life can maintain a habitable environment in hostile conditions, research suggests
Everybody knows that for life to thrive on any world, you need water, warmth, and something to eat. It's like a habitability mantra. But, what other factors affect habitability? What if you relaxed the conditions conducive to life? Would it still exi.....»»
Forest fires are shifting north and intensifying—here"s what that means for the planet
Fires have long been a natural part of forest ecosystems, but something is changing. Our new study shows that forest fires have become more widespread and severe amid global heating, particularly in the high northern latitudes such as Canada and Sibe.....»»
Coastal cities have a hidden vulnerability to storm-surge and tidal flooding that"s entirely caused by humans
Centuries ago, estuaries around the world were teeming with birds and turbulent with schools of fish, their marshlands and endless tracts of channels melting into the gray-blue horizon......»»
EarthCARE synergy reveals power of clouds and aerosols
With the initial images from each of the instruments aboard ESA's EarthCARE satellite now in hand, it's time to reveal how these four advanced sensors work in synergy to measure exactly how clouds and aerosols influence the heating and cooling of our.....»»
Researchers uncover role of plasma waves in mysterious heating of sun"s corona
There is a profound mystery in our sun. While the sun's surface temperature measures around 10,000 degrees Fahrenheit, its outer atmosphere, known as the solar corona, measures more like 2 million degrees Fahrenheit, about 200 times hotter......»»
The Hunt for Life on Europa Is About to Kick Up a Gear
NASA’s Europa Clipper mission is set for launch, finally revealing if this icy moon of Jupiter is habitable or not......»»
Survey reveals Australians" lukewarm response to urgent action on global heating
An annual climate action survey has highlighted concern for the Great Barrier Reef (GBR) and a desire for renewables over nuclear power, however, Australians impacted by the cost-of-living crisis seem less enthusiastic on taking climate change action.....»»
Tidal Cyber empowers organizations to improve their protection efforts
Tidal Cyber announced that it now incorporates test results from Breach and Attack Simulation (BAS) tools and other sources to complement the company’s existing Threat-Informed Defense capabilities. With this new integration, Tidal Cyber Enterprise.....»»
AMD vs. Intel: Who makes the best CPUs?
With AMD's Ryzen 9000 here and Intel's Arrow Lake on the way, the rivalry between Intel and AMD is only heating up......»»
Potential indicators of life on other planets can be created in a lab
One way to understand the potential for life on far-off planets—those in other solar systems that orbit different stars—is to study a planet's atmosphere. Telescopic images often capture traces of gases that may indicate life and habitable planet.....»»
Could stars hotter than the sun still support life?
Although most potentially habitable worlds orbit red dwarf stars, we know larger and brighter stars can harbor life. One yellow dwarf star, for example, is known to have a planet teaming with life, perhaps even intelligent life. But how large and bri.....»»
Advanced civilizations will overheat their planets within 1,000 years, researchers suggest
Earth's average global temperatures have been steadily increasing since the Industrial Revolution. According to the National Oceanic and Atmospheric Agency (NOAA), Earth has been heating up at a rate of 0.06°C (0.11°F) per decade since 1850—or ab.....»»
"Doomsday" glacier set to melt faster and swell seas as world heats up, say scientists
Tidal action on the underside of the Thwaites Glacier in the Antarctic will "inexorably" accelerate melting this century, according to new research by British and American scientists. The researchers warn the faster melting could destabilize the enti.....»»
Aversion to inequality drives support for redistribution policies, study finds
As income inequality widens, debates around redistribution policies are heating up. New research from the Universities of Zurich, Lille and Copenhagen reveals that support for these policies stems not only from individuals' financial situations but a.....»»
