Researchers Claim Robust ‘Universal Computer Memory’ Breakthrough

Lancaster University has announced a “universal computer memory” breakthrough combining the fast, low-energy storage of DRAM memory with the robustness of flash memory. They’re now envisioning ultra-low energy consumption computers which would never need to boot up — and can “instantaneously and imperceptibly” slip into an energy-saving sleep mode. Long-time Slashdot reader Hrrrg pointed us to this announcement:
A U.S. patent has…

Main instrument for NASA’s WFIRST mission completes milestone review

In order to know how the universe will end, we must know what has happened to it so far. This is just one mystery NASA’s forthcoming Wide Field Infrared Survey Telescope (WFIRST) mission will tackle as it explores the distant cosmos. The spacecraft’s giant camera, the Wide Field Instrument (WFI), will be fundamental to this exploration. Source: https://phys.org/news/2019-06-main-instrument-nasa-wfirst-mission.html…

The first AI universe sim is fast and accurate—and its creators don’t know how it works

For the first time, astrophysicists have used artificial intelligence techniques to generate complex 3-D simulations of the universe. The results are so fast, accurate and robust that even the creators aren’t sure how it all works. Source: https://phys.org/news/2019-06-ai-universe-sim-fast-accurateand.html…

Galaxy clusters caught in a first kiss

For the first time, astronomers have found two giant clusters of galaxies that are just about to collide. This observation can be seen as a missing ‘piece of the puzzle’ in our understanding of the formation of structure in the universe, since large-scale structures—such as galaxies and clusters of galaxies—are thought to grow by collisions and mergers. The result was published…

Model suggests how early dark energy could resolve the Hubble tension

The universe is continuously expanding, yet the exact rate at which it does so remains unclear, and has so far only been approximated using NASA’s Hubble Space Telescope and other similar instruments. Moreover, in recent years, astronomers using the Hubble telescope have unveiled a discrepancy between the two primary techniques used for estimating the universe’s expansion rate.
