Laser Fusion Experiment Unleashes an Energetic Burst of Optimism
An anonymous reader quotes a report from The New York Times: Scientists have come tantalizingly close to reproducing the power of the sun -- albeit only in a speck of hydrogen for a fraction of a second. Researchers at Lawrence Livermore National Lab.....»»
Nuking a huge asteroid could save Earth, lab experiment suggests
Humanity could use a nuclear bomb to deflect a massive, life-threatening asteroid hurtling towards Earth in the future, according to scientists who tested the theory in the laboratory by blasting X-rays at a marble-sized "mock asteroid"......»»
Radiation should be able to deflect asteroids as large as 4 km across

Proof-of-concept study uses X-rays to target mock-up asteroids in a vacuum
An X-ray pulse may be able to vaporize the surface of an asteroid and change its trajectory, according to a proof-of-concept paper published in Nature Physics. A laboratory experiment that mimics the deflection of an asteroid model using this techniq.....»»
New results from the CMS experiment put W boson mass mystery to rest
After an unexpected measurement by the Collider Detector at Fermilab (CDF) experiment in 2022, physicists on the Compact Muon Solenoid experiment (CMS) at the Large Hadron Collider (LHC) announced today a new mass measurement of the W boson, one of n.....»»
Even the heaviest particles experience the usual quantum weirdness, new experiment shows
One of the most surprising predictions of physics is entanglement, a phenomenon where objects can be some distance apart but still linked together. The best-known examples of entanglement involve tiny chunks of light (photons), and low energies......»»
The Dyson V15 cordless vacuum is $200 off for a limited time
The Dyson V15 Detect Extra cordless vacuum, which uses a green laser to reveal hidden dust, is available from Best Buy for only $600 following a $200 discount......»»
Researchers identify novel endocytic recycling mechanism with "kiss-and-run" membrane fusion
Endocytosis and recycling control the uptake and retrieval of various materials in eukaryotic cells. Mammalian cells have developed several recycling routes, including the relatively extensively studied "fast" and "slow" tubulovesicular recycling pat.....»»
Life might thrive on the surface of Earth for an extra billion years
The sun is midway through its life of fusion. It's about 5 billion years old, and though its life is far from over, it will undergo some pronounced changes as it ages. Over the next billion years, the sun will continue to brighten......»»
Researchers build AI model database to find new alloys for nuclear fusion facilities
A study led by the Department of Energy's Oak Ridge National Laboratory details how artificial intelligence researchers have created an AI model to help identify new alloys used as shielding for housing fusion applications components in a nuclear fus.....»»

Groundbreaking experiment may let us ‘see’ gravity for the first time ever
Scientists have spent decades trying to understand how gravity operates at its most basic scale. However, no theory has come close to fully explaining it. … The post Groundbreaking experiment may let us ‘see’ gravity for the first time ever.....»»
Real-time Linux is officially part of the kernel after decades of debate
Now you can run your space laser or audio production without specialty patches. Enlarge / Cutting metal with lasers is hard, but even harder when you don't know the worst-case timings of your code. (credit: Getty Images).....»»
Optimism fuels national productivity and innovation
A study of 42 countries over a 20-year span found one factor had a significant impact on investment in research and development. Economic optimism plays a crucial role in boosting national productivity and research and development, according to a new.....»»
Tracking plasma progression in a picosecond: Physicists develop ultra-fast laser method to study high-density plasmas
In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term—the metal is nearly 200,000 degrees Fahrenheit. With the short.....»»
Scientists quantify energetic costs of the migratory lifestyle in a free flying songbird
Millions of birds migrate every year to escape winter, but spending time in a warmer climate does not save them energy, according to research by the Max Planck Institute of Animal Behavior (MPI-AB). Using miniaturized loggers implanted in wild blackb.....»»
Denver"s experiment in providing a soft landing for newly arrived migrants is expensive but necessary, says researcher
The burden of supporting asylum-seekers with food and housing often falls to cities, creating severe budget crunches. But Denver is piloting a new approach designed to integrate immigrants into the workforce faster......»»

The Hisense laser projector on sale at Best Buy today (PL1 X-Fusion) will create anywhere from an 80-inch screen up to 120-inches. A real home movie theater......»»
Generating spin currents directly using ultrashort laser pulses
An international team of physicists has found that it is possible to generate spin currents directly using certain kinds of ultrashort laser pulses. In their study, published in the journal Physical Review Letters, the group used a linearly polarized.....»»
Huge gamma-ray burst collection "rivals 250-year-old Messier catalog," say astronomers
Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it "rivals the catalog of deep-sky objects created by Messier 250 years ago", astronomers say......»»
