Neutral particles a drag on disruptive plasma blobs
For decades, scientists have been working to harness clean, renewable fusion energy, which occurs naturally in stars like our sun. Using strong magnetic fields to confine hot plasmas within a donut-shaped device called a tokamak, researchers can gene.....»»
In a fusion device plasma, a steep ion temperature gradient slows the growth of magnetic islands
Future fusion power plants will require good plasma confinement to sustain reactions and generate energy. One way to contain plasma for fusion reactions is to use a tokamak, a device that applies magnetic fields to "bottle" plasma. However, magnetic.....»»
First coherent picture of an atomic nucleus made of quarks and gluons
The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of atomic nuclei hitherto observ.....»»
China"s child policies will increase its future carbon emissions, researchers say
Relaxing its restrictions on family size would make it more difficult for China to achieve its goal to be carbon neutral by 2060, according to a new study by UCL researchers......»»
Researchers uncover role of plasma waves in mysterious heating of sun"s corona
There is a profound mystery in our sun. While the sun's surface temperature measures around 10,000 degrees Fahrenheit, its outer atmosphere, known as the solar corona, measures more like 2 million degrees Fahrenheit, about 200 times hotter......»»
Event horizon: After photographing black holes, scientists are now making a movie
The first moving images of a black hole could reveal swirls of plasma and collapsing stars, deepening our understanding of the universe......»»

Weaker China results a drag on BMW, Mercedes Q3 sales
BMW's sales in China fell 30 percent, the steepest drop in more than four years. Mercedes sales declined 13 percent after Chinese buyers held back purchases of expensive models......»»
US forecasts severe solar storm starting Thursday
A massive ball of plasma and accompanying magnetic field ejected from the sun is expected to strike Earth on Thursday morning, potentially triggering auroras as far south as Alabama, according to US forecasters......»»
Quantum register reaches 1,200 neutral atoms in continuous operation
A team of physicists led by Johannes Zeiher, research group leader in Immanuel Bloch's Quantum Many-Body Systems department and co-founder of the MPQ spin-off planqc, has achieved significant progress in scaling up quantum computing platforms with ne.....»»
Neural networks boost fusion research with rapid ion temperature and rotation velocity predictions
In fusion experiments, understanding the behavior of the plasma, especially the ion temperature and rotation velocity, is essential. These two parameters play a critical role in the stability and performance of the plasma, making them vital for advan.....»»

Influence of a black hole"s spin: First evidence of precession in ultraluminous accretion disks
Gas swirls around a black hole due to its intense gravity, forming an accretion disk. These accretion disks, being among the most efficient energy conversion mechanisms in the universe, emit light and plasma jets. When a black hole spins on its axis,.....»»
Surprising amount and variety of gamma radiation is produced in large tropical thunderstorms, observations reveal
In the 1990s, NASA satellites built to spot high-energy particles coming from supernovas and other celestial-sized objects discovered a surprise—high energy gamma radiation bursts coming from right here on Earth......»»
A new and unique fusion reactor comes together due to global research collaboration
