Quenching the intense heat of a fusion plasma may require a well-placed liquid metal evaporator
Inside the next generation of fusion vessels known as spherical tokamaks, scientists at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) envisioned a hot region with flowing liquid metal that is reminiscent of a subterranean.....»»
Nanofibers made of copper-binding peptides disrupt cancer cells
While toxic in high concentrations, copper is essential to life as a trace element. Many tumors require significantly more copper than healthy cells for growth—a possible new point of attack for cancer treatment......»»
Collaboration key to ultimate genotypes in plants and livestock, say researchers
University of Queensland researchers are setting the agenda for breeding high yield, heat tolerant and disease-resistant crops and low emission cattle with excellent feed conversion efficiency as they search for the ultimate genotype......»»
Emergent gravity may be a dead idea, but it’s not a bad one
Gravity may not emerge, but some interesting ideas did. Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a.....»»
Why Hypochondria Can Be Deadly, and How Newer Treatments Help
Intense health anxiety is a true mental illness and threatens lives. The good news is that it’s treatable.....»»
I used the HMD Fusion, 2024’s bravest smartphone
This is the bravest smartphone I've used this year, solely because it's attempting something many others have failed at: Nailing modular phones......»»
The Galaxy S25 could add a new feature that’s perfect for mobile gaming
The Galaxy S25 could come with a new Game Assist mode that doubles the frame rate without affecting battery life or heat output......»»
These Rats Learned to Drive—and They Love It
Driving represented an interesting way for neuroscientists to study how rodents acquire new skills, and unexpectedly, rats had an intense motivation for their driving training......»»
Saturday Citations: Cold dark matter takes a hit; a new paradigm for biology; those fracking earthquakes
This week, researchers formulated a new method to calculate the probability of generating intelligent life in the universe. Investigations of a meteorite that originated on Mars revealed that it once interacted with liquid water. And an analysis of f.....»»
Extreme heat weakens land"s power to absorb carbon, analysis finds
A new European Space Agency-backed study shows that the extreme heat waves of 2023, which fueled huge wildfires and severe droughts, also undermined the land's capacity to soak up atmospheric carbon. This diminished carbon uptake drove atmospheric ca.....»»
New family of optimized omnigenous magnetic fields could display enhanced fusion plasma confinement
Physicists have been trying to design fusion reactors, technologies that can generate energy via nuclear fusion processes, for decades. The successful realization of fusion reactors relies on the ability to effectively confine charged particles with.....»»
Shanghai, Tokyo, New York, Houston spew most greenhouse gas of world cities
Cities in Asia and the United States emit the most heat-trapping gas that feeds climate change, with Shanghai the most polluting, according to new data that combines observations and artificial intelligence......»»
Study finds humidity diminishes daytime cooling gains in urban green spaces
Urban green spaces provide shade for city dwellers facing rising temperatures brought on by climate change, but how much relief from the heat island effect do they provide when humidity is factored in?.....»»
New route to quantum spin liquid materials discovered
A new route to materials with complex disordered magnetic properties at the quantum level has been produced by scientists for the first time. The material, based on a framework of ruthenium, fulfills the requirements of the Kitaev quantum spin liquid.....»»
Trump’s Election Threatens Heat Protections for Workers
A Biden administration proposal that would require employers to provide cooling measures under extreme heat conditions may be scuttled by the incoming Trump administration.....»»
Industrial snow: Factories trigger local snowfall by freezing clouds
Anthropogenic aerosols, tiny solid and liquid air pollution particles, have masked a fraction of global warming caused by anthropogenic greenhouse gases. Climate researchers have known for decades that anthropogenic aerosols perturb liquid clouds by.....»»
Meteorite contains evidence of liquid water on Mars 742 million years ago
An asteroid struck Mars 11 million years ago and sent pieces of the red planet hurtling through space. One of these chunks of Mars eventually crashed into the Earth somewhere near Purdue University and is one of the few meteorites that can be traced.....»»
Metal-organic framework materials to remove dye contaminants for cleaner water
The future of MOFs, metal-organic framework materials, looks bright. A review in the International Journal of Environment and Waste Management has looked at how a specific class of these sponge-like materials might find increasing use in removing dye.....»»
Tesla is recalling 2,431 Cybertrucks, and this time there’s no software fix
Owners of the affected trucks will require replacement hardware. Tesla has issued yet another recall for the angular, unpainted Cybertruck. This is the sixth recall affecting the.....»»
iOS 18.2 beta 3 adds new ‘Require Screen On’ toggle for Camera Control
iOS 18.2 beta 3 adds another new toggle for personalizing the iPhone 16’s Camera Control. Now, you can open the Camera app with a single press of the Camera Control even if your display is off. more….....»»
Study reveals why carbon boosts metal nanoparticle catalysts
Precious metals play an important role in the chemical industry as catalysts: With the help of silver, platinum, palladium or other elements, chemical reactions can take place that would otherwise not progress or would only progress at a much lower r.....»»
