The Sun is a plasma diffuser that selectively moves light elements like H and He and the lighter isotopes of each element to its surface. The Sun formed on the collapsed core of a supernova (SN) and is composed mostly of elements made near the SN core (Fe, O, Ni, Si, and S), ...
only the solid plates beneath those two continents could resist the great pushing forces they exerted. There were about 12,000 Earth Engines built and distributed across the Asian and American plains. From my home I could see the bright plasma plumes(等离子气柱)of several hundred Earth Engines....
As tempting as it is to cite one, no single number can describe the temperature of the whole Sun. Its layers are at different temperatures because they're doing very different things. The Sun is a gigantic dynamo powered by hydrogen fusion within its plasma core. At pressures in the trillio...
Nearly all visible matter is made of plasma: the sun, gas clouds, stars and galaxies. In nature, we can observe plasma in the form of northern lights , when the air molecules of the Earth's atmosphere, excited by the plasma of the solar winds, glows in green, blue, red, and violet....
The sun is a ball of gas—a special kind of gas to be sure. It is so hot in some regions in the interior that the atoms have come apart completely to form a state of matter known as a plasma—an electrically charged gas. To understand the physical processes that cause stars, like ...
For decades we have known that the Sun lies within the Local Bubble, a cavity of low-density, high-temperature plasma surrounded by a shell of cold, neutral gas and dust1–3. However, the precise shape and extent of this shell4,5, the impetus and timesca
The increased activity has sent waves of high-energy plasma and X-ray bursts slamming into Earth'smagnetic fields, downing Starlink satellites, triggering radio blackouts and causing auroras as far south asPennsylvania, Iowa, and Oregon. And the most intense activity may still lie ahead....
The surface of the sun is electrically active and it is completely covered by the photosphere. The sun's surface rotates uniformly every 27.3 days unlike the plasma layer of the photosphere.
Apolipoprotein E4 (APOE4) is the strongest known genetic risk factor for late-onset Alzheimer’s disease (AD). Conditions of stress or injury induce APOE expression within neurons, but the role of neuronal APOE4 in AD pathogenesis is still unclear. Here we report the characterization of neurona...
Molecular stratification can improve the management of advanced cancers, but requires relevant tumor samples. Metastatic urothelial carcinoma (mUC) is poised to benefit given a recent expansion of treatment options and its high genomic heterogeneity. We profile minimally-invasive plasma circulating tumor DN...
