Chaotic electrons heed "limit" in strange metals
Electrons in metals try to behave like obedient motorists, but they end up more like bumper cars. They may be reckless drivers, but a new Cornell-led study confirms this chaos has a limit established by the laws of quantum mechanics......»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»
Layered superconductor coaxed to show unusual properties with potential for quantum computing
A team led by researchers from the California NanoSystems Institute at UCLA has designed a unique material based on a conventional superconductor—that is, a substance that enables electrons to travel through it with zero resistance under certain co.....»»
Scientists identify the predictability limit of oceanic mesoscale eddy tracks in the South China Sea
Oceanic mesoscale eddies (OMEs) are swirling water structures that play a crucial role in ocean dynamics. These eddies transport heat, salt, nutrients, and other materials across the ocean, significantly influencing marine ecosystems and global clima.....»»
Madison Symmetric Torus operates stable plasma at 10 times the Greenwald Limit
If net-positive fusion energy is to ever be achieved, density is key: the more atomic nuclei crashing into each other, the more efficient the reaction will be. Nearly 40 years ago, Martin Greenwald identified a density limit above which tokamak plasm.....»»
Star Trek: Lower Decks S5 teaser gives Cerritos crew one last mission
Also: teaser for Section 31, news on Strange New Worlds S3, Starfleet Academy, and more. "Lower decks! Lower decks!" The fifth season of Star Trek: Lower Decks will be the animated series' last (boo!). Star Trek: Lower Decks is a pa.....»»
People are arguing about this classic macOS feature, and it’s hilarious
A simple post on X ignited a firestorm of debate over whether macOS or Windows does one simple thing better. The results were amusing and often very strange......»»
Researchers develop high-sensitivity technique to detect mercury in soil
Environmental pollution by heavy metals is a major social problem. Among these metals, mercury (Hg) is strictly controlled due to its high toxicity. Focusing on soil, which is closely related to our daily lives, the environmental standard for mercury.....»»
"Miracle" filter turns store-bought LEDs into spintronic devices
Traditional electronics use semiconductors to transmit data through bursts of charged carriers (electrons or holes) to convey messages in "1s" and "0s." Spintronic devices can process an order of magnitude more information by assigning binary code to.....»»
Liquid metals offer potential for greener chemical processes, researchers say
University of Sydney researchers are proposing a new way to curb industrial emissions, by tapping into the "atomic intelligence" of liquid metals to deliver greener and more sustainable chemical reactions......»»
Humanity suffering from "extreme heat epidemic," UN chief warns
Humanity is suffering from an "extreme heat epidemic," UN Secretary-General Antonio Guterres warned Thursday, calling for action to limit the impacts of heat waves intensified by climate change......»»
Unequal access to quantum information education may limit progress—now is the time to improve
Quantum information science uses the physics that describes the smallest particles—such as electrons or photons—to potentially revolutionize computing and related technologies. This new field can be used for a wide range of applications, from dev.....»»
Woodchip bioreactor helps reduce pesticide run-off from horticulture greenhouses
Pesticides seeping out of intensive horticulture into waterways have long-concerned NSW north coast communities. Now a new Southern Cross University study provides evidence that bioreactors can significantly limit this toxic run-off......»»
Researchers zero in on the underlying mechanism that causes alloys to crack when exposed to hydrogen-rich environments
When deciding what material to use for infrastructure projects, metals are often selected for their durability. However, if placed in a hydrogen-rich environment, like water, metals can become brittle and fail. Since the mid-19th century, this phenom.....»»
Will burying biomass underground curb climate change?
Though carbon removal startups may limit global warming, significant questions remain. (credit: TEEIC) On April 11, a small company called Graphyte began pumping out beige bricks, somewhat the consistency of particle boa.....»»
Microfluidic sensors enable real-time detection of multiple heavy metals in water
A group of researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has designed and developed advanced microfluidic sensor arrays that use fluorescent probes to simultaneously visualize and quantitatively detect m.....»»
A new way to control the magnetic properties of rare earth elements
The special properties of rare earth magnetic materials are due to the electrons in the 4f shell. Until now, the magnetic properties of 4f electrons were considered almost impossible to control......»»
Morals are key to consumer views on lab-grown meat, study finds
People's moral values could limit their uptake of lab-grown meat, a study suggests. People who say living a natural life is morally important to them are more likely to reject lab-grown meat—also known as cultured or cultivated meat—than those wh.....»»
Study reveals key gene protecting plants from harmful metals in soil
The negative impact of human activity on Earth doesn't just affect our planet's atmosphere—it goes much deeper, into its soils. For instance, excessive application of manure or sewage sludge can increase heavy metal concentrations in agricultural l.....»»
Switch 2 is around the corner, but Nintendo announces a new Switch accessory anyway
Oddly timed accessory is released as the Switch's life cycle is winding down. Nintendo's Joy-Con Charging Stand (Two-Way) seems useful, but it's coming out at a strange time in.....»»
Small steps for electrons—big steps for the future? Ultrafast microscope reveals electron pathways in solar cells
In the search for more efficient and sustainable energy generation methods, a class of materials called metal halide perovskites have shown great promise. In the few years since their discovery, novel solar cells based on these materials have already.....»»
