As part of its plan to go carbon-neutral by 2030, Microsoft is considering replacing its diesel backup generators with hydrogen battery storage. The company has successfully kept part of one of its datacenters online for 48 hours on hydrogen power alone.

Datacenters are massive facilities that are usually full of servers and any variety of other computer or telecoms equipment. They might house the daily or even hourly backups from financial institutions and other high-demand users, because the wrong kind of disaster could wipe out a bank’s entire internal network.

“Alder Lake,” Intel’s family of 12th Generation processors, has arrived—and with it, a new CPU paradigm. Intel’s Core i9-12900K desktop CPU ($589) leads the pack of the company’s 12th Generation processors, and brings with it a whole host of upgrades and innovations to the desktops of now and tomorrow. These tick-ups include support for the new, high-speed DDR5 RAM standard, as well as an upgrade to PCI Express 5.0, on the first new motherboard platform to support the latest chips, the Intel Z690. Intel also worked closely with Microsoft to optimize the new CPUs for Windows 11, adding new scheduling features that intelligently load up the Core i9-12900K depending on which cores are being used where, and for what.

Alder Lake and the Core i9-12900K indeed impress, but our relationship with the CPU…is complicated. For all the outright wins we saw in our benchmarks (and there were many), the added cost of upgrading to yet another new motherboard platform won’t outweigh the win percentages for many shoppers. Intel’s older-yet-still-reliable “Comet Lake” Core i9-10900K kept itself in the race during several benchmarks, while the eight-core, rather cheaper AMD Ryzen 7 5800X ($449 list price, but currently snipe-discounted to $386 on Amazon and Newegg) proves itself a worthy contender on performance-versus-price in PC gaming.

The high cost of a new Z690 motherboard (the cheapest are just under $200, per our Z690 motherboard guide) and DDR5 adoption, along with Intel’s insistence on upgrading your system to Windows 11, are all front-facing considerations for anyone who’s considering 12th Generation Core as their next big desktop upgrade. That—and a not-insignificant problem in which our test platform, and several prebuilt Alder Lake PCs, could not launch certain popular games that use specific DRM—temper Alder Lake with a bit of wait-and-see caution. Our initial Alder Lake takeaway is “Intel’s on the upswing, with some caveats.” But read more about our findings below.

Astronomers at The University of Texas at Austin’s McDonald Observatory have discovered an unusually massive black hole at the heart of one of the Milky Way ’s dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies — the building blocks of the universe — evolve. The work is published in a recent issue of The Astrophysical Journal.

The team decided to study Leo I because of its peculiarity. Unlike most dwarf galaxies orbiting the Milky Way, Leo I does not contain much dark matter. Researchers measured Leo I’s dark matter profile — that is, how the density of dark matter changes from the outer edges of the galaxy all the way into its center. They did this by measuring its gravitational pull on the stars: The faster the stars are moving, the more matter there is enclosed in their orbits. In particular, the team wanted to know whether dark matter density increases toward the galaxy’s center. They also wanted to know whether their profile measurement would match previous ones made using older telescope data combined with computer models.

Researchers at Microsoft have developed a faster way to write data into DNA — a biological alternative to the bits on a hard drive.

Quantum computer and many other quantum technologies rely on the generation of quantum-entangled pairs of electrons. However, the systems developed so far typically produce a noisy and random flow of entangled electrons, which hinders synchronized operations on the entangled particles. Now, researchers from Aalto University in Finland propose a way to produce a regular flow of spin-entangled electrons.

Their solution is based on a dynamically driven Cooper pair splitter. In a Cooper pair splitter, two quantum dots near a superconductor are used to generate and separate a pair of entangled electrons known as a Cooper pair. When the Cooper pair splitter is driven with a static voltage, the result is a random and noisy process.

A theoretical analysis by the Aalto team showed that driving the system dynamically with external gate voltages makes it possible to control the timing of the splitting process. As a result, exactly one pair of entangled electrons can be extracted during each splitting cycle, leading to a completely noiseless and regular flow of spin-entangled electrons.

However, the $799 product can still run PC games, thanks to the integrated graphics on the CPU.

One of the first goals of quantum computing has been to recreate bizarre quantum systems that can’t be studied in an ordinary computer. A dark-horse quantum simulator has now done just that.
