ITER fusion reactor to see further delays, with operations pushed to 2034
Full fusion power won't happen until nearly 2040 on new timeline. Enlarge / One of the components of the reactor during leak testing. (credit: ITER) On Tuesday, the people managing the ITER experimental fusion reactor an.....»»
Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect
Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly,.....»»
This crew is leaving their simulated ‘Martian’ habitat after 378 days
Four volunteers for a NASA experiment have spent more than a year confined to a simulated version of a Mars habitat -- and now they're being let out......»»
Blue and great tits deploy surprisingly powerful memories to find food, finds study
Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to.....»»
"Acceleration beats" shine bright light on a novel universal modulation regime in a semiconductor-based laser
Researchers at the Paul-Drude-Institute for Solid State Electronics (PDI) have observed a novel modulation regime characterized by the emergence of previously unseen "acceleration beats" in a modulated semiconductor-based laser......»»
Study shows slow-growth diet before breeding offers better long-range health in pigs
Borrowing a page from the dairy industry, researchers with the Arkansas Agricultural Experiment Station found that a slow-growth diet meant more piglets and healthier and longer-lived momma pigs......»»
Nectarivores: A world of sweet-toothed critters
If you have a sweet tooth, you'll be familiar with the burst of energy known as a sugar rush. But what if your survival depended on it? Would you love it as much? Animals get the nutrients they need from different sources......»»
Chandra X-ray Observatory"s clear, sharp photos help astrophysicist study energetic black holes
When a star is born or dies, or when any other very energetic phenomenon occurs in the universe, it emits X-rays, which are high-energy light particles that aren't visible to the naked eye. These X-rays are the same kind that doctors use to take pict.....»»
DNA repair mechanism further elucidated in cryo-electron microscopy experiment
Researchers have discovered how the protein XPD detects severe DNA damage and controls its repair......»»
Apple versus donut: How the shape of a tokamak impacts the limits of the edge of the plasma
Harnessing energy from plasma requires a precise understanding of its behavior during fusion to keep it hot, dense and stable. A new theoretical model about a plasma's edge, which can become unstable and bulge, brings the prospect of commercial fusio.....»»
Fish are adapting to weightlessness on the Chinese space station
Four zebrafish are alive and well after nearly a month in space aboard China's Tiangong space station. As part of an experiment testing the development of vertebrates in microgravity, the fish live and swim within a small habitat aboard the station......»»
After a child"s death, California weighs rules for physical education during extreme weather
Yahushua Robinson was an energetic boy who jumped and danced his way through life. Then, a physical education teacher instructed the 12-year-old to run outside on a day when the temperature climbed to 107 degrees......»»
The Artificial Intelligence Era Faces a Threat from Directed Energy Weapons
Autonomous and AI-enabled systems increasingly rely on optical and radio frequency sensors and significant computer power. They face growing vulnerabilities from directed-energy laser and microwave weapons.....»»
Researchers unveil tritium release behavior of solid breeder irradiated with fusion neutron
A research group led by Prof. Wang Haixia from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has revealed the tritium release behavior of lithium titanate (Li2TiO3) breeder irradiated with fusion neutrons, which contribu.....»»
Observing mammalian cells with superfast soft X-rays
Researchers have developed a new technique to view living mammalian cells. The team used a powerful laser, called a soft X-ray free electron laser, to emit ultrafast pulses of illumination at the speed of femtoseconds, or quadrillionths of a second......»»
Theory and experiment combine to shine a new light on proton spin
Nuclear physicists have long been working to reveal how the proton gets its spin. Now, a new method that combines experimental data with state-of-the-art calculations has revealed a more detailed picture of spin contributions from the very glue that.....»»
Canon imageClass MF654cdw review: a low-cost, high-quality color laser printer
Canon's imageClass MF654cdw is a high-quality color laser printer at a budget price, so we checked what tradeoffs were made to make it so affordable......»»
New discoveries about the nature of light could improve methods for heating fusion plasma
Both literally and figuratively, light pervades the world. It banishes darkness, conveys telecommunications signals between continents and makes visible the invisible, from faraway galaxies to the smallest bacterium. Light can also help heat the plas.....»»
