Scientists design novel nonlinear circuit to harvest clean power using graphene
Obtaining useful work from random fluctuations in a system at thermal equilibrium has long been considered impossible. In fact, in the 1960s eminent American physicist Richard Feynman effectively shut down further inquiry after he argued in a series.....»»
After a century away, sturgeons return to Swedish waters
A century after it disappeared from Swedish waters, scientists in June embarked on a 10-year project to reintroduce the Atlantic sturgeon to a cleaned-up river in the west of the country......»»
Researchers upend AI status quo by eliminating matrix multiplication in LLMs
Running AI models without matrix math means far less power consumption—and fewer GPUs? Enlarge / Illustration of a brain inside of a light bulb. (credit: Getty Images) Researchers claim to have developed a new way to r.....»»
“Energy-smart” bricks need less power to make, are better insulation

Is generative AI really going to “wreak havoc” on the power grid?
AI is just one small part of data centers’ soaring energy use. Enlarge / Someone just asked what it would look like if their girlfriend was a Smurf. Better add another rack of servers! (credit: Getty Images) Late last.....»»
US to launch satellite to better prepare for space weather
The United States is aiming Tuesday to launch a new satellite expected to significantly improve forecasts of solar flares and coronal mass ejections—huge plasma bubbles that can crash into Earth, disrupting power grids and communications......»»
Researchers develop MoonIndex, open-source software that allows study of lunar surface
With MoonIndex, researchers from Constructor University and the National Institute of Astrophysics in Italy have developed an open-source software that for the first time gives scientists access to a free tool that creates science-ready products from.....»»
Shaping the future of polymer nanocarriers
Scientists have taken a significant step towards the development of tailor-made chiral nanocarriers with controllable release properties. These nanocarriers, inspired by nature's helical molecules like DNA and proteins, hold immense potential for tar.....»»
A model of Collaborative Ethics to guide translational research from fundamental discoveries to real-world applications
In sciences, disruptive research that is breaking new ground often raises new and not-yet-explored ethical questions. Although new scientific breakthroughs can have the power to change how we understand and live in the world, the ethical implications.....»»
Tea science: Gene discovery to boost mechanical harvesting
Researchers have made significant strides in understanding the genetic factors influencing tea plant leaf droopiness, a key determinant of mechanical harvest success. By identifying the CsEXL3 gene and its regulation by CsBES1.2, the study paves the.....»»
Using supercomputer researchers discover new clues to improving fusion confinement
Nuclear fusion—when two nuclei combine to form a new nucleus, thereby releasing energy—may be the clean, reliable, limitless power source of the future. But first, scientists must learn how to control its production......»»
Quantum annealer improves understanding of quantum many-body systems
Physicists have long been pursuing the idea of simulating quantum particles with a computer that is itself made up of quantum particles. This is exactly what scientists at Forschungszentrum Jülich have done together with colleagues from Slovenia......»»
Jupiter"s upper atmosphere surprises astronomers
Using the NASA/ESA/CSA James Webb Space Telescope, scientists observed the region above Jupiter's iconic Great Red Spot to discover a variety of previously unseen features. The region, previously believed to be unremarkable in nature, hosts a variety.....»»
Marine cloud brightening models show unexpected consequences of geoengineering
A combined team of Earth scientists and climate specialists at the University of California San Diego and the National Center for Atmospheric Research has found via modeling that geoengineering projects such as marine cloud brightening can have unexp.....»»

World not ready for climate change-fueled wildfires: Experts
The world is unprepared for the increasing ferocity of wildfires turbocharged by climate change, scientists say, as blazes from North America to Europe greet the northern hemisphere summer in the hottest year on record......»»
New tipping point discovered beneath the Antarctic ice sheet
A new and worrying way that large ice sheets can melt has been characterized by scientists for the first time. The research focuses on how relatively warm seawater can lap at the underside of ground-based ice, which can accelerate the movement of the.....»»
Scientists identify safe havens we must preserve to prevent "the sixth great extinction of life on Earth"
In a new article, a coalition of conservationists and researchers have shown how we can protect Earth's remaining biodiversity by conserving just a tiny percentage of the planet's surface. This affordable, achievable plan would make it possible for u.....»»
Using sound waves, scientists develop findings that challenge standard theories of solar convection
A team of solar physicists at NYU Abu Dhabi's Center for Astrophysics and Space Science (CASS), led by Research Scientist Chris S. Hanson, Ph.D., has revealed the interior structure of the sun's supergranules, a flow structure that transports heat fr.....»»
