Nvidia’s latest game-ready driver includes a tool that could let you improve the image quality of games that your graphics card can easily run, alongside optimizations for the new God of War PC port. The Verge reports: The tech is called Deep Learning Dynamic Super Resolution, or DLDSR, and Nvidia says you can use it to make “most games” look sharper by running them at a higher resolution than your monitor natively supports. DLDSR builds on Nvidia’s Dynamic Super Resolution tech, which has been around for years. Essentially, regular old DSR renders a game at a higher resolution than your monitor can handle and then downscales it to your monitor’s native resolution. This leads to an image with better sharpness but usually comes with a dip in performance (you are asking your GPU to do more work, after all). So, for instance, if you had a graphics card capable of running a game at 4K but only had a 1440p monitor, you could use DSR to get a boost in clarity.

DLDSR takes the same concept and incorporates AI that can also work to enhance the image. According to Nvidia, this means you can upscale less (and therefore lose less performance) while still getting similar image quality improvements. In real numbers, Nvidia claims you’ll get image quality similar to running at four times the resolution using DSR with only 2.25 times the resolution with DLDSR. Nvidia gives an example using 2017’s Prey: Digital Deluxe running on a 1080p monitor: 4x DSR runs at 108 FPS, while 2.25x DLDSR is getting 143 FPS, only two frames per second slower than running at native 1080p.

fahrbot-bot shares a report from Ars Technica: Space isn’t easy on humans. Some aspects are avoidable — the vacuum, of course, and the cold, as well as some of the radiation. Astronauts can also lose bone density, thanks to a lack of gravity. NASA has even created a fun acronym for the issues: RIDGE, which stands for space radiation, isolation and confinement, distance from Earth, gravity fields, and hostile and closed environments. New research adds to the worries by describing how being in space destroys your blood. Or rather, something about space — and we don’t know what just yet — causes the human body to perform hemolysis at a higher rate than back on Earth.

This phenomenon, called space anemia, has been well-studied. It’s part of a suite of problems that astronauts face when they come back to terra firma, which is how Guy Trudel — one of the paper’s authors and a specialist in physical medicine and rehabilitation at The Ottawa Hospital — got involved. “[W]hen the astronauts return from space, they are very much like the patients we admit in rehab,” he told Ars. Space anemia had been viewed as an adaptation to shifting fluids in the astronauts’ upper bodies when they first arrive in space. They rapidly lose 10 percent of the liquid in their blood vessels, and it was expected that their bodies destroyed a matching 10 percent of red blood cells to get things back into balance. People also suspected that things went back to normal after 10 days. Trudel and his team found, however, that the hemolysis was a primary response to being in space. “Our results were a bit of a surprise,” he said. […]

Trudel’s team isn’t sure exactly why being in space would cause the human body to destroy blood cells at this faster rate. There are some potential culprits, however. Hemolysis can happen in four different parts of the body: the bone marrow (where red blood cells are made), the blood vessels, the liver, or the spleen. From this list, Trudel suspects that the bone marrow or the spleen are the most likely problem areas, and his team has plans to investigate the issue further in the future. “What causes the anemia is the hemolysis, but what causes the hemolysis is the next step,” he said. It’s also uncertain how long a person in space can continue to destroy 54 percent more red blood cells than their Earth-bound kin. “We don’t have data beyond six months. There’s a knowledge gap for longer missions, for one-year missions, or missions to the Moon or Mars or other bodies,” he said.

An anonymous reader quotes a report from ScienceNews: Meet the kunga, the earliest known hybrid animal bred by people. The ancient equine from Syro-Mesopotamia existed around 4,500 years ago and was a cross between a donkey and a hemippe, a type of Asiatic wild ass, researchers report January 14 in Science Advances. Horses didn’t appear in this region of Asia until 4,000 years ago, centuries after their domestication in Russia. But dozens of equine skeletons were excavated in the early 2000s from a royal burial complex dating back to 2600 B.C. at Umm el-Marra in northern Syria. The animals, whose physical features didn’t match any known equine species, appear to be “kungas” — horselike animals seen in artwork and referenced in clay tablets predating horses by centuries.

“They were highly valued, very expensive,” says paleogeneticist Eva-Maria Geigl of Institut Jacques Monod in Paris. Geigl and her colleagues analyzed a kunga’s genome, or genetic instruction book, and compared it with those of horses, donkeys and Asiatic wild asses, including the hemippe (Equus hemionus hemippus), which has been extinct since 1929. The kunga’s mother was a donkey and its father a hemippe, making it the oldest evidence of humans creating hybrid animals. A mule from 1000 B.C. in Anatolia reported by the same research group in 2020 is the next oldest hybrid. Geigl thinks kungas were created for warfare, as they could pull wagons. Coaxing donkeys into dangerous situations is hard, she says, and no Asiatic wild ass can be tamed. But a hybrid might have had the characteristics people sought.

The new German government is proposing a bold new initiative to dramatically increase onshore wind power in the country by 2030. “If successful, the plan would add up to 10 gigawatts of new onshore wind capacity every year for the rest of the decade,” reports CleanTechnica. “In total, 2% of Germany’s land area will be set aside for wind energy generation. [T]he German government also plans to increase its offshore wind target to 30 GW by 2030.” From the report: During a press conference, [the nation’s new Green Minister for Economics and Climate, Robert Habeck] made it clear that wind energy, particularly onshore wind, will remain the most important source of electricity in Germany and is the key to further emission reductions, according to WindEurope. “The Energiewende is roaring again. Germany wants a huge expansion of onshore wind. And the Government fully understands that that requires faster permitting of new wind farms — and they intend to deliver this ASAP with a dedicated new ‘Onshore Wind Law.’ Today’s announcements mark the comeback of German leadership on renewables — fantastisch!” says WindEurope CEO Giles Dickson.

Habeck intends to remove restraints on onshore wind development caused by concerns about radar installations for civilian and military aviation. He estimates the government plan could free up 4 to 5 GW of new wind projects currently blocked by aviation radar, and an additional 4 GW currently blocked by the military. Support for renewable energies will be paid from the state budget, reducing the burden on low income households and small businesses. The package is also said to define the energy transition as a ‘matter of public interest’ in order to prioritize wind energy projects over other forms of land use — an important precondition to streamlining the permit process and finding new sites for wind energy projects.

Germany’s federal cybersecurity watchdog, the BSI, did not find any evidence of censorship functions in mobile phones manufactured by China’s Xiaomi, a spokesperson said on Thursday. Reuters reports: Lithuania’s state cybersecurity body had said in September that Xiaomi phones had a built-in ability to detect and censor terms such as “Free Tibet,” “Long live Taiwan independence” or “democracy movement.” The BSI started an examination following these accusations, which lasted several months. “As a result, the BSI was unable to identify any anomalies that would require further investigation or other measures,” the BSI spokesperson said.

An anonymous reader quotes a report from Electrek: New satellite images show that Tesla significantly expanded its rooftop solar array at Gigafactory Nevada as it aims for it to become the world’s biggest. In 2017, Tesla announced plans for a giant 70 MW rooftop array at Gigafactory Nevada, which would be the largest in the world by a wide margin. The project has been lagging for a long time. Tesla finally started construction of the solar array in 2018 and expanded on it throughout the next few years, but it has never grown near the size Tesla has been talking about. Last summer, the automaker said that it had deployed 3.2 MW at the site. At the time, Tesla also changed its goal to deploy 24 MW instead of 70 MW on the rooftop of the factory, which itself is now smaller than originally planned. The company said that it believes this would still be enough to be the largest rooftop deployment of solar power. To be fair, there are much bigger solar farms than 24 MW out there, but Tesla is specifically talking about rooftop solar arrays and not ground-mounted installations.

Now a few months later, it looks like Tesla has made a lot of progress with several more MW of solar power deployed at Gigafactory Nevada based on new satellite images. The image on the left is from September 2021 and the one on the right is from yesterday, January 12 (via Building Tesla). It’s hard to determine exactly how much capacity Tesla deployed, but it looks like a significant increase over the last few months. As for the factory itself, it has been expanding in size for a long time. The factory has been producing a lot of battery cells, packs, and drivetrains for Tesla, but the giant structure has been stuck at ~30% completion for the past four years.

The U.S. Federal Trade Commission and multiple states are investigating Meta’s virtual reality unit Oculus over potential anti-competitive practices. Bloomberg reports: The FTC and a group of states led by New York have quizzed outside developers that make Oculus apps in recent months as part of the inquiry, the people said. The officials have been scrutinizing how Meta, the world’s largest social media company, may be using its market power in the VR space to stifle competition, said the people, who asked not to be identified because the matter isn’t public. In interviews with several developers, the antitrust enforcers asked how the Oculus app store may be discriminating against third parties that sell apps that compete with Meta’s own software. They were also curious about Meta’s sales strategy for the Oculus VR headset and how the price of the company’s device undercuts competitors. Meta sells the Oculus Quest 2 headset for $299, well below some models from HTC Corp. and others.

The FTC and states including New York, Tennessee and North Carolina began reaching out to developers concerned about Oculus-related antitrust issues last year, one of the people said. […] Developers have complained that Meta uses its market power to thwart companies that offer competing games and services on Oculus. They allege the company copies the most promising ideas and makes it harder for some apps to work properly on the platform. […] The antitrust scrutiny could complicate Meta’s plans to build out what Chief Executive Officer Mark Zuckerberg calls the metaverse — immersive digital worlds accessed through virtual and augmented reality-powered devices. Zuckerberg has said he thinks the devices will become the next major computing platform for human communication, after mobile phones, eventually replacing some in-person interactions.
