Supercomputer turns back cosmic clock
Astronomers have tested a method for reconstructing the state of the early universe by applying it to 4000 simulated universes using the ATERUI II supercomputer at the National Astronomical Observatory of Japan (NAOJ). They found that together with n.....»»
AMD starts bringing its own tiny CPU cores to new Ryzen 7040 laptop chips
AMD has already announced some of these chips without mentioning Zen 4c cores. Enlarge / Unlike Intel's E-cores, AMD's Zen 4c supports all the same capabilities as Zen 4, just in a smaller package with lower clock speeds. (credit.....»»
New-generation RO constellation "spire" challenges COSMIC-2 in atmospheric remote sensing
In a recent study, scientists from the Aerospace Information Research Institute (AIR) under the Chinese Academy of Sciences (CAS) investigated the performance of a commercial Global Navigation Satellite System (GNSS) Radio Occultation (RO) mission an.....»»
The sun"s activity cycle is reaching its peak early—knowing why could help us unlock the secrets of our star
Our sun is a steady and everlasting companion. Reliable like a clock, its apparent passage across the sky allows us to measure time. The sun and its path is also the source of Earth's seasons. But in many respects, our sun is far from calm and unchan.....»»
Astronomers capture formation of a powerful cosmic jet
Using a network of radio telescopes on Earth and in space, astronomers have captured the most detailed view ever of a jet of plasma from a supermassive black hole. The jet travels at nearly the speed of light and shows complex, twisted patterns near.....»»
Arctic archipelago turns the page on its mining past
At the old Svea mine in the Arctic, broken railway tracks overgrown with weeds lead nowhere. Of the hundred buildings that once made up the town, there's almost nothing left......»»

How Nvidia and AMD could make Windows laptops feel like MacBooks
In an unexpected twist, it turns out that Nvidia and AMD may be developing ARM-based CPUs. Does Apple need to worry, and what about Intel?.....»»
In 250 million years, a single supercontinent will form, wiping out nearly all mammals: Modeling study
A recent study published in Nature Geoscience uses supercomputer climate models to examine how a supercontinent, dubbed Pangea Ultima (also called Pangea Proxima), that will form 250 million years from now will result in extreme temperatures, making.....»»
Wildfire smoke leaves harmful gases in floors and walls—air purifiers aren"t enough, new study shows
When wildfire smoke turns the air brown and hazy, you might think about heading indoors with the windows closed, running an air purifier or even wearing a mask. These are all good strategies to reduce exposure to the particles in wildfire smoke, but.....»»
RIP to my 8-port Unifi switch after years and years of Texas outdoor temps
Turns out that only lightning could kill my otherwise-unkillable US-8-150W. Enlarge / My original US-8-150W shortly before being replaced. Don't judge my zip-tie mounting job—it held for eight years! (credit: Lee Hutchinson).....»»
Astronomers detect most distant fast radio burst to date
An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Larg.....»»
New observations confirm important step in star formation
New observations have confirmed a key step in the process of star formation: a rotating "cosmic wind" made of molecules, which is vitally important for collapsing gas clouds to contract sufficiently so as to form a hot, dense young star......»»

New map of space precisely measures nearly 400,000 nearby galaxies
Astronomers have created a detailed atlas of almost 400,000 galaxies in our cosmic neighborhood. The Siena Galaxy Atlas was compiled using data from NSF's NOIRLab telescopes, and is designed to be the preeminent digital galaxy atlas for large galaxie.....»»
Apple did kind of announce a new iPad after all… in China
After conflicting reports about whether Apple was going to launch new iPads, a new Apple Pencil, or both, the matter appeared to have been settled with yesterday’s announcement of the Apple Pencil (USB-C). However, it turns out there was a new(i.....»»
Protostars can siphon material from far away, says study
When stars are born, they do it inside a molecular cloud. Astronomers long assumed that the "crèche" supplied all the nutrients that protostars needed to form. However, it turns out they get help from outside the nest......»»
