Throughout the ocean, billions upon billions of plant-like microbes make up an invisible floating forest. As they drift, the tiny organisms use sunlight to suck up carbon dioxide from the atmosphere. ...
A wildfire can pump smoke up into the stratosphere, where the particles drift for over a year. A new MIT study has found that while suspended there, these particles can trigger chemical reactions that...

We derive the classical compressible Euler equation as the limit of 3D quantum N-particle dynamics as N tends to infinity and Planck's constant tends to zero. We establish strong and quantitative conv...
The international LHCb collaboration at the Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of “pentaquark” and the first-ever pair of “tetraquarks”, which inclu...
Polaritons offer the best of two very different worlds. These hybrid particles combine light and molecules of organic material, making them ideal vessels for energy transfer in organic semiconductors....
High-energy collisions at the Large Hadron Collider (LHC) allow researchers to clearly study heavy Standard Model particles, like the Higgs boson, that decay almost immediately at the LHC collision po...
Acommon building material, asbestos is the term used to describe a range of naturally growing minerals. Serious diseases, including mesothelioma and lung cancer, can arise decades after coming into co...
Scientists make first detection of exotic “X” particles in quark-gluon plasma（图）
夸克 胶子 等离子体 “X”粒子
2023/6/9
In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons — elementary particles that briefly glommed together in countless combin...
When it comes to creating next-generation electronics, two-dimensional semiconductors have a big edge. They’re faster, more powerful and more efficient. They’re also incredibly difficult to fabricate.
The LHCb collaboration has measured a difference in mass between two particles of 0.00000000000000000000000000000000000001 grams – or, in scientific notation, 10-38 g. The result, reported in a paper ...
