The chaotic cores of Perseus protostars
The formation of a star has a simple tale. A region of interstellar gas collapses under its own weight, eventually forming a dense protostar surrounded by a disk of gas and dust. The protostar and the disk rotate in the same plane, and often jets of.....»»
Chaotic electrons heed "limit" in strange metals
Electrons in metals try to behave like obedient motorists, but they end up more like bumper cars. They may be reckless drivers, but a new Cornell-led study confirms this chaos has a limit established by the laws of quantum mechanics......»»
Some strange Intel Core 12900K, 12700K, and 12600K specs have appeared online
Some of the leaked specifications appear strange, but not in an unexpected way. Alder Lake CPUs have been confirmed by Intel to have Golden Cove and Gracemont cores inside, so each processor has two core counts and two clock speeds......»»
AMD"s Zen 4-based Ryzen 6000 CPUs will probably be limited to 16 cores
Hardware leaker ExecutableFix tweeted the news yesterday. If true, it contradicts previous rumors of AMD adding a third chiplet to Zen 4, which would have increased the core count to 24. But it seems we’ll have to make do with “just” sixteen. T.....»»
Solar radio signals could be used to monitor melting ice sheets
The sun provides a daunting source of electromagnetic disarray—chaotic, random energy emitted by the massive ball of gas arrives to Earth in a wide spectrum of radio frequencies. But in that randomness, Stanford researchers have discovered the maki.....»»
Injured baby elephant abandoned by rogue Chinese herd saved
A heavily injured baby elephant left behind by a migrating wild herd in southwest China has been rescued, state media reported Tuesday, the latest twist in a chaotic odyssey......»»
A pair of sparkling galaxies shine in this Hubble image
This week's beautiful image of space captured by Hubble shows two large galaxies, part of the Perseus cluster, against a background starfield......»»
The most ancient ice in the Alps will be preserved in Antarctica
The Ice Memory international mission on Monte Rosa has been accomplished. After working for five days at 4,500 meters in the accumulation zone of the Grenzgletscher, the glacier saddle of Colle Gnifetti, scientists extracted three shallow ice cores (.....»»
Astronomers probe layer-cake structure of brown dwarf"s atmosphere
Brown dwarfs are the cosmic equivalent of tweeners. They're too massive to be planets and too small to sustain nuclear fusion in their cores, which powers stars. Many brown dwarfs are nomadic. They do not orbit stars but drift among them as loners......»»
Alienware vBIOS abducts CUDA cores from the RTX 3070
Things aren't going well with Dell's Alienware gaming notebooks as of late. With the Alienware Graphics Amplifier external GPU recently killed off in favor of Thunderbolt 4 solutions, and the class-action lawsuit now being brought against the adverti.....»»
Jets from massive protostars might be very different from lower-mass systems
Astronomers studying the fast-moving jet of material ejected by a still-forming, massive young star found a major difference between that jet and those ejected by less-massive young stars. The scientists made the discovery by using the U.S. National.....»»
White dwarf stars" debris disk formation delayed
White dwarfs, the glowing cores of dead stars, often host disks of dusty debris. However, these debris disks only appear 10 to 20 millions of years following the star's violent Red Giant phase. A new paper by Planetary Science Institute Research Sci.....»»
Dead zones formed repeatedly in North Pacific during warm climates, study finds
An analysis of sediment cores from the Bering Sea has revealed a recurring relationship between warmer climates and abrupt episodes of low-oxygen "dead zones" in the subarctic North Pacific Ocean over the past 1.2 million years......»»
Taking Lyft’s new e-bike for a spin
The bike had none of the usual signage when I took it for a spin around the chaotic and construction-filled streets of Manhattan. It very much looked like a prototype, with visible soldering on the joints and a not-quite-complete AV system. But it ha.....»»
Nvidia unveils the GeForce RTX 3080 Ti: RTX 3090-like performance at $1200; RTX 3070 Ti arrives on June 10 for $600
Talk of an RTX 3080 Ti has been around since Ampere was unveiled. Once thought to feature 20GB of GDDR6X, Nvidia confirmed the card comes with 12GB—half that of the RTX 3090. Its GA102-225 GPU features 10,240 CUDA cores with a total of 80 Streaming.....»»

Study reveals diverse magnetic fields in solar-type star forming cores
Magnetic fields are ubiquitous throughout the Milky Way galaxy and play a crucial role in all dynamics of interstellar medium. However, questions like how solar-type stars form out of magnetized molecular clouds, whether the role of magnetic fields c.....»»
