After a major ChatGPT outage on Wednesday, OpenAI confirmed it was due to a DDoS attack. A cyberattack is to blame for recent ChatGPT outages. OpenAI confirmed this Wednesday on its status monitoring site saying, the outages are "due to an abno.....»»
Developer shows progress on QEMU-based iPhone OS emulator, now running version 2.1
We wrote last year about a developer who successfully emulated iPhone OS on a Mac using QEMU. At the time, the original firmware of the 1st generation iPod touch was used to demonstrate that emulating iPhone and iPod touch software is possible. Now M.....»»
How machine learning can support data assimilation for Earth system models
Data assimilation is the combination of the latest observations with a short-range forecast to obtain the best possible estimate of the current state of the Earth system. Machine learning can contribute to it by optimizing the use of satellite observ.....»»
Gate induced room-temperature magnetic phase transition realized in van der Waals ferromagnet nanoflakes
By intercalating protons into van der Waals ferromagnet Cr1.2Te2 nanoflakes, a group of researchers successfully induced a room-temperature magnetic phase transition from ferromagnetism to antiferromagnetism......»»
A new trail to exoplanets: Team successfully detects ammonia isotopologues in atmosphere of cold brown dwarf
They reveal the origin of wine, the age of bones and fossils, and they serve as diagnostic tools in medicine. Isotopes and isotopologues—molecules that differ only in the composition of their isotopes—also play an increasingly important role in a.....»»
The first assimilation of CryoSat-2 summer observations provides accurate estimates of Arctic sea ice thickness
Scientists have improved a data assimilation system for better estimating Arctic summer sea ice thickness (SIT) by assimilating satellite-based summer SIT and ice concentration data with an incremental analysis update (IAU) approach. Their study show.....»»
Researchers create a breathable alveolus in vitro
Researchers from Zhejiang University have successfully constructed biomimetic alveoli outside the human body that can replicate the process of human breathing......»»
The JWST Has Spotted Giant Black Holes All Over the Early Universe
Giant black holes were supposed to be bit players in the early cosmic story. But James Webb Space Telescope observations are finding an unexpected abundance of the beasts......»»
Scientists describe deployment of three-body chain-type tethered satellites in low-eccentricity orbits
Recently, the tethered satellite system (TSS) has been used in Earth observations, space interferometry and other space missions, due to its potential merits. The tethered TSAR (tomographic synthetic aperture radar) system is a group of tethered SAR.....»»
Research explores the properties of supernova remnant 1E 0102.2–7219
Using the Australia Telescope Compact Array (ATCA) and the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has observed a supernova remnant known as 1E 0102.2–7219. Results of the study, presented October 2.....»»
What"s inside the Carina pillars? Massive protostars and newly forming planets
Star-forming nebulae are busy places. Unfortunately, clouds of gas and dust usually hide the action. To cut through the dust in one such region, a team of astronomers used the Atacama Large Millimeter Array (ALMA). They peered inside the Pillars of t.....»»
New research sheds light on early galaxy formation
Researchers have developed a new computer simulation of the early universe that closely aligns with observations made by the James Webb Space Telescope (JWST)......»»
Scientists isolate early-warning tremor pattern in lab-made earthquakes
Researchers at The University of Texas at Austin have successfully isolated a pattern of lab-made "foreshock" tremors. The finding offers hope that future earthquakes could be forecast by the swarm of smaller tremors that come before them......»»
W1055+5443 is a Y-type brown dwarf, observations find
Using the Keck II telescope, astronomers have performed near-infrared spectroscopic observations of a nearby brown dwarf known as CWISE J105512.11+544328.3, or W1055+5443 for short. Results of the observational campaign, presented October 14 on the p.....»»
