    DEI is DOA NASA moves swiftly to end DEI programs, asks employees to report violations "Failure to report this information within 10 days may result in adverse consequences."

Credit: HUM Images/ Universal Images Group via Getty Images Story textSizeSmallStandardLargeWidth *StandardWideLinksStandardOrange* Subscribers only Learn moreNASA's acting administrator is moving swiftly to remove diversity, equity, inclusion, and accessibilityor DEIAprograms from the space agency.In an email sent to agency employees on Wednesday afternoon, acting administrator Janet Petro wrote, "We are taking steps to close all agency DEIA offices and end all DEIA-related contracts in accordance with President Trumps executive orders titled Ending Radical and Wasteful Government DEI Programs and Preferencing and Initial Rescissions of Harmful Executive Orders and Actions."During his run for a second term as president, Trump campaigned on ending programs in the federal government that promote diversity, equity, and inclusion. He signed executive orders to that effect shortly after his inauguration on Monday.Programs seen as divisiveThese programs had their roots in affirmative action but exploded in popularity half a decade ago amid Trump's first presidency and the #MeToo and Black Lives Matter movements. DEI programs and officers became commonplace in academia and major US corporations. However, even before the election of Trump, the DEI movement appeared to have crested. For example, last year the Massachusetts Institute of Technology ended the use of diversity statements for faculty hiring.In explaining NASA's position, Petro said of the agency's existing DEIA activities, "These programs divided Americans by race, wasted taxpayer dollars, and resulted in shameful discrimination."Petro's email is notable for its suggestion that some civil servants at NASA may have sought to shroud DEIA programs from the Trump administration since the presidential election in early November."We are aware of efforts by some in government to disguise these programs by using coded or imprecise language," she wrote. "If you are aware of a change in any contract description or personnel position description since November 5, 2024 to obscure the connection between the contract and DEIA or similar ideologies, please report all facts and circumstances."Petro's message includes an email address to report such activities and asks NASA employees to do so within 10 days."There will be no adverse consequences for timely reporting this information," Petro wrote. "However, failure to report this information within 10 days may result in adverse consequences."NIH and NSF affectedNASA is not the only federal agency where this is happening. Several other agencies received similarly worded messages from their acting directors on Wednesday.Due to the poor representation of minorities in science and engineering fields, both of the major federal funding agenciesthe National Institutes of Health and the National Science Foundationhave programs designed to encourage participation by underrepresented communities. These include educational programs, funding to enable research done by undergraduates, and support for students in graduate school all directed toward members of underrepresented groups. As of 5 pm ET, webpages for most of these programs are still available, though one entitled Broadening Participation in Training Programs at the NIH was no longer available.For the medical research community, however, the termination of these programs might be the least of its concerns. As of Tuesday, all external communication from agencies within the Department of Health and Human Services, which includes the NIH, Centers for Disease Control, and the Food and Drug Administration, were put on hold. This will include things like alerts regarding the spread of emerging diseases, such as the H5N1 bird flu thats currently widespread in agricultural animals.But today, it became clear that this policy extended well beyond external communications. One researcher said that an NIH workshop was canceled mid-presentation. Others have reported that all evaluations of grant proposals by the NIH are now on hold indefinitely. Should the hold last for any significant amount of time, it will have severe ripple effects, as arranging the peer review panels that evaluate grants involves complicated scheduling and travel, so the delays may persist for considerably longer.Eric BergerSenior Space EditorEric BergerSenior Space Editor Eric Berger is the senior space editor at Ars Technica, covering everything from astronomy to private space to NASA policy, and author of two books: Liftoff, about the rise of SpaceX; and Reentry, on the development of the Falcon 9 rocket and Dragon.

  • Nvidia RTX 5090 review: face-meltingly good top-flight performance and gorgeous industrial design - but beware the electrical bill
    www.vg247.com
    Pulling PowerNvidia RTX 5090 review: face-meltingly good top-flight performance and gorgeous industrial design - but beware the electrical billNvidias latest flagship GPU is only for the most dedicated hardware sickos - but for those of you so inclined, the 5090 is an absolute joy.Image credit: Nvidia/VG247 Article by Alex Donaldson Assistant Editor Published on Jan. 23, 2025 Its that most exciting time in the world of PC gaming once again: graphics card generational shift oclock! As always, Nvidia leads with its flagship, most expensive card, intended only for the most dedicated nutters with the deepest pockets: the Nvidia GeForce RTX 5090. The headline? Its bloody good stuff - but one has to be prepared to shell out big-time, even if not at the point of purchase.Lets talk about the price first, because its a barrier to entry that might see some of you Grandpa Simpson U-Turn right on out of this review. The Founders Edition of the 5090 - that is to say the benchmark version of the card made by Nvidia itself - runs $1999, or 1939. Versions from other vendors will vary around this price point. Needless to say, this is a hefty chunk of change, and isnt for the faint-hearted. Then again, this is the GPU equivalent of buying a Bugatti - Nvidia knows all too well who its target audience is.To see this content please enable targeting cookies. In real terms, this is an RRP price increase over last generations RTX 4090 of around 25%. The matter of whether this is reasonable can be answered by pitching a simple question: does the performance uplift match the price uplift?The answer, to spoil the rest of this review up front, is yes. Generally speaking and depending on the software, players can expect a 20-30% uplift in the performance of their games from the 5090 over its last-generation sibling - meaning the dollar increase matches pretty closely to improvements in rasterization and FPS - and thats without getting into other features.The biggest (or perhaps smallest, depending on your angle) new feature of the 5090 becomes clear the moment you pop open its pleasing new eco-friendly but no less theatrical box - its small. Or, well look. Its a two-slot GPU. Its a normal-sized two-slot GPU. But as someone who has been using the 4090 for the last few years and had to completely reorganize my PC case to fit that beast in, the size of this thing is a revelation.The 4090 was giving potential murder weapon vibes with its heft, size, and boxy shape. The 5090 is a complete design rethink inside and out. The cooling solution, internal layout, and even PCB shape have been carefully reconsidered. Cards have been shaken around on industrial earthquake-makers in order to test that no matter what you put it through its slick new liquid metal cooling solution doesnt leak. Gone is the asymmetrical fan layout that has defined Nvidias Founders Edition cards for so long, replaced with something at once more traditional and quite revelatory.A deep dive into the making of the GeForce RTX 5090.Watch on YouTubeFrom a design standpoint, what I most like is the softer curved edges of this design. Like I say, this is a normal two-slot card, but by softening the edges and by noting that this is a more powerful card that is nevertheless much smaller than its predecessor, this thing feels smaller than it is. Other changes are just plain smart, like the tiny but instantly perceptible and appreciated decision to angle the power cable - making for a neater fit in even the smaller-end of cases.All of that is just aesthetics, of course, and the truth is these things are devices that you hold in your hands and marvel at briefly before shoving them into a PC case to never look at again. What matters is the performance, which as Iev said is an uplift of 20-30% over the 4090. Its worth noting that this is actually much less of a jump than the 3090 to the 4090 - but its a smaller price jump, too.Running with a 9800x3D processor at native 4K, and crucially with DLSS frame generation technology turned off, most of todays biggest graphics benchmark hits run at well in excess of 100fps. To talk about a few of them in brief:The 5090 humbles Cyberpunk 2077s Ultra preset (without RT), managing to run at almost 100fps consistently, and often well above it. This is a big leap - the headline with the 4090 was that you could enjoy Cyberpunk on Ultra at 60fps. One generation later and we're approaching doubling that. Flick that Ray Tracing option to its 'psycho' variant and lo, you can get a full 60fps - without frame generation. Real-time ray tracing with no AI, we're here!Indiana Jones and the Great Circle is a game really driven by its use of real-time lighting solutions, and should become a great future benchmark. Albeit without full path tracing, on the 4090 this game already ran slightly above 100fps comfortably even on its Very Ultra setting - but on the 5090 you can now hit the nice round benchmark lock of 120fps. In fact, it comfortably coasts at close to 135-140fps. Thats an uplift of around 20% versus the previous generation card, which itself is quite the beast.Alan Wake 2 enjoys a handsome 50-series boost also in the 20% range, though this one modern game that struggles to break the 3-figure barrier. Back on the 4090, we could only just about scrape close to 60fps without turning on frame generation features. On the 5090, we can finally lock to 60 - or flex to a little beyond. Slick bit of kit. | Image credit: NvidiaA huge part of these cards, however, is the extra technology. Ray Tracing is no longer just a buzzword - increasingly, its becoming an essential component of some of todays best-looking games. Even on the most powerful cards ray tracing can decimate raw raster performance. If were being literal, in fact, it more than decimates performance. This is where DLSS frame generation comes in - and with the new series of cards comes DLSS4 and a new feature Nvidia is particularly proud of, multi-frame generation.If youre reading a review for a graphics card that costs two grand, you probably very well know what DLSS and frame generation is. But for the avoidance of doubt, heres the quick-fire crash course: DLSS stands for Deep Learning Super Sampling, which is a process that uses machine learning and AI to allow a graphics card to improve the image quality and frame rate of games beyond what the hardware is capable of on its own.Basically, the performance of any game exists on an axis of resolution versus quality. If you want high resolution and high quality, its more taxing - which can often drop the frame rate. But DLSS provides an enticing solution to this problem: what if the GPU renders the game at a lower resolution, but then lets a meticulously-trained AI step in to increase the image quality? The result is that you can have a game like Cyberpunk with maxed out settings, including the most ridiculous real-time lighting available - and still enjoy silky smooth frame rates.Its a cheat, its true, but as the DLSS technology has improved, a DLSS upscaled image has become increasingly hard to distinguish from a raw and natural 4K output - and DLSS4 tweaks and improves the technology further. Multi-frame generation (MFG) is an additional powerful string to Nvidias bow, now allowing for up to three new frames to be generated by AI for every one natural frame put out by the GPU. The fake frames aim to help make everything smoother. Largely, MFG is aimed at people with 240hz displays and the like - if you can run a game at 4K 120fps natively, for instance, MFG can comfortably get you to 240hz - which is neat. No, it's not cheap. | Image credit: NvidiaMFG works well in the games currently supported by it, though I think there is inevitably going to be heated debate about the validity and quality of gaming with the faked frames. How a game feels to play will only ever be impacted by the natural frames a GPU generates, after all - frame-gen will help whats put out to appear smoother, however - and appearances are indeed important.MFG is clearly a technology that is going to be very important in years to come, though as it stands right now perhaps what is more interesting is other improvements to DLSS that arrive alongside it to make it viable. Tweaks and changes to the system mean that frames should now be better-paced, for instance, which means that the stutter that could sometimes plague DLSS3 is less likely. The good news, too, is that much of this tech is available to older-generation RTX cards - though everything will inevitably run best on the 5090.As has been the case with other Nvidia RTX GPUs, flicking on Ray Tracing, DLSS, and now MFG results in a transformative experience. Going for the maximum level of ray tracing in a game like Alan Wake 2 or Cyberpunk 2077 tanks the natural frame rate, but these systems bring you right back up to breezy, smooth frame rates - and unlike with the earliest versions of this technology, theres no feeling of compromise. It just works, as Nvidias CEO likes to say.The important thing is that this technology doesnt exist here to paper over the cracks of an under-powered card. Quite the opposite, in fact: it is the nitrous oxide that gets fired into the engine that is the GPU in order to make for an even more impressive output. Any uplift offered in pure rasterization is matched - or bettered - when you start flicking these bonus features on. Its in these features, and the strength of their technology and software, which is now unified in the easy-to-understand Nvidia App, that give Nvidia their edge. This is just our slant on the unit. | Image credit: NvidiaWhichever way you slice it, this is record-setting performance. Such performance also comes, it has to be noted, with record-setting power consumption. To keep up my stretched-thin automotive analogy, this baby is a gas-guzzler. Ive never seen a graphics card draw power quite like this, in fact. I saw draws well in excess of 500 watts for the card. Theres no two ways about it - it will be expensive to run. Every cloud has a silver lining, though, and given the power draw I was pleasantly surprised at the temperatures the card manages to maintain when being pushed hard.I summed it up earlier: this is not a card for the faint of heart. You need the sort of PC to make its power worthwhile, where youre not going to run into a CPU bottleneck. You need the money in the bank to drop on the card - and then the willingness to swallow the energy bills. But if you fall into that category, this is the new flagship product not just for Nvidia - but for PC graphics in general. Its best-in-class, and its an astonishingly good piece of kit. For the average player, however, one step down might be wisest - and you can expect word from us on the RTX 5080 soon.

    Hillo ThereFancy some chill off-roading with cosy vibes? Art of Rally and Absolute Drift dev Funselektor's next game, Over The Hill, looks like it'll crank your winchIn a good way, and with the same cool minimalistic art style the studio's made its trademark.Image credit: Funselektor/Strelka Games News by Mark Warren Senior Staff Writer Published on Jan. 23, 2025 Funselektor, the studio behind indie racing games Art of Rally, Absolute Drift, and last year's Golden Lap - all of which are very cool if you're into artsy takes on things that go vroom vroom, has just announced it and collaborator Strelka Games' next title.It's a cosy off-roader called Over The Hill, and it looks like the answer to the question 'What if the likes of Snowrunner and Euro Truck Simulator grew their hair out a bit and stopped caring so much about power-to-weight ratio numbers?'To see this content please enable targeting cookies. Inspired by Funselektor founder Dune Casu's adventures through the North American wilderness in a camper van, Over The Hill is all about free-roaming exploration chill enough that you can philosophise while you do it. You and an optional mate will strap into not quite Land Rover Defenders and be able to roam different off-road environments, with "hidden gems, objectives and challenges such as offroad trails" being out there to discover.As you can see in the trailer below, immersion and vibes are big goal here, with a day-and-night cycle and weather changing dynamically as you roam about, trying to not roll over and pancake the kayak you've probably got strapped to your roof.Watch on YouTubeYou're armed with a trusty winch, of course, so here's hoping it'll prove as much as a reliable best buddy/lifesaver when you inevitably plant your right foot and do something dumb as it is in more hardcore off-road sims."After having developed several games about motorsport, we wanted to go off-track by offering players a vast world to lose themselves at a slower pace," Casu said of Over The Hill, adding: "Theres something special about being in the wilderness in the middle of nowhere, from the peace, the sounds of nature and less distraction from the civilized world. I hope this game can really drive that feeling home."Lord knows we all need a distraction from (gestures) the world right now, so hopefully Over The Hill does deliver a good way to do so when it releases down the line. For now, it's wishlistable on Steam.

  • Surgent Studios Enters Publishing Collaboration With Palworld's Pocketpair
    www.nintendolife.com
    As buggy and choppy as it was on Nintendo Switch, I LOVED Tales Of Kenzera: Zau.It was a truly moving story, had some decent elements in combat and conveyance that made me feel really invested. The framerates were not consistent, but the game still had the feel of guiding a nimble young warrior through a powerful journey, which it was, emotionally and otherwise.I truly want to see more Tales Of Kenzera, be they more myths and stories like Zau, or more focused on the amazing afro-futuristic setting bookending the game's story.The bookend segments of the futuristic main character were very touching and well thought out, and the setting was much like the Marvel movies' images of Wakanda, which I also liked.

  • Tives tools help companies track the status of their shipments in real time
    techcrunch.com
    The global supply chain is under strain, and one of the reasons is a lack of visibility into how shipments are being transported around the world. According to one recent survey, nearly half of the organizations polled reported having little-to-no visibility into their upstream supply chains.In search of a remedy, Krenar Komoni, whod for years helped his father-in-law track his truck fleet, founded Tive, a startup thats developing tech to pinpoint freight shipments in real time.Tive sells single-use tracking devices that can be linked to its cloud platform to let companies in industries like life sciences and food and beverage check the status of their freight. In addition to tracking location, Tives sensors can monitor temperature, humidity, light, and shock i.e. physically violent motions.Through Tives cloud platform, its customers can get real-time alerts, analytics, and data sharing tools.Tive trackers have generated millions of real-time shipment alerts, Komoni told TechCrunch in an interview. Our trackers provide a three-pronged approach to location accuracy, combining cellular triangulation, Wi-Fi positioning, and GPS.Tive didnt start as a freight-tracking company. In its early days, the startup focused on helping carriers and truckers track their vehicles. But Komoni, who has a background in radio frequency and chip design engineering, saw a much bigger opportunity in monitoring shipments themselves.One of Tives wireless tracking devices. Image Credits:TiveTive claims to have more than 900 customers today in sectors like pharmaceuticals and high-value goods, as well as military and government clients. The company is generating revenue from those customers in a number of ways, Komoni says, including through annual software fees for its cloud platform, tracker sales and shipment monitoring services.Komoni expects Tive will reach profitability in 2026.Tives focus on supply chain solutions for all types of goods durable, nondurable, perishable, industrial, consumer, and so on positions it well to weather broader tech slowdowns and recessions, Komoni said. Despite the freight recession, which has been the norm since the end of COVID-19, Tive has consistently grown 50%+ year-over-year, and expects to grow at an accelerated rate in 2025.To expand its Boston-based workforce of around 243 employees, Tive recently raised $40 million in a Series C round co-led by by World Innovation Lab and Sageview Capital with participation from AVP, RRE Ventures, TwoSigma Ventures, Qualcomm Ventures, Fifth Wall, Supply Chain Ventures, and Sorenson Capital.The new capital brings Tives total raised to $120 million. In addition to hiring, Komoni said the new cash will be put toward developing new products, expanding Tives sustainability programs (including its tracker recycling program), and bringing the platform to more countries.

  • Y Combinator grad Spacium raises oversubscribed $6.3M for space re-fueling
    techcrunch.com
    Back in 2023, Ashi Dissanayake, cofounder of in-space fueling startup Spacium, was so bootstrapped she used the surface of her clothes dryer as a desk, sticking her legs inside the drying machine. Her computer was perched beside Tide Pods and she was surrounded by disembodied robotic arms, working late into the night with her cofounder, Reza Fetanat. Back then, the pair worked out of a tiny Ottawa apartment.Since then, theyve moved to an office with real desks, gone through Y Combinator, and, today, announced an oversubscribed $6.3 million seed round led by Initialized Capital. The company is planning a demo mission of their product capabilities later this year, and Dissanayake said they have a strong pipeline of customers.The two cofounders bonded at University of Ottawa over their mutual space obsession and teamed up for research projects. We were building the rockets, rocket structures, propulsion system, as well as the parachutes that would bring the rocket back, she said, adding they would put samples in the rockets, shoot them up as high as 30,000 feet, and then send the data back to Canadian labs.As they worked on research, Dissanayake and Fetanat realized that the biggest bottleneck in the industry was the lack of refueling options in space. Right now, a spacecraft has to be equipped with all the fuel it needs for a mission. And after the mission ends, the spacecraft basically becomes space debris, she said.For longer missions or deep space missions like, say, colonizing Mars companies will need to have access to fuel in space. Our big mission would be to build the space super highway, where we have multiple refueling stations where a spacecraft can come dock, refill, and go about their way, she said.Spacium is not the only company with this dream: Orbit Fab is also working on in-space refueling, and has a several year head start. Additionally, Japanese aerospace company Astroscale won a $25.5 million U.S. Space Force contract to build a refueling vehicle.But Dissanayake feels confident they have a competitive advantage. We have actually developed a very unique system where we can store the fuel for longer periods of time, which was actually not done before, she said, declining to give further details.Dissanayake has a long way to go, but she hopes one day she can take a trip up to space, look out into the abyss, and then actually see our stations from where we are.Topics

  • Breaking Down EyeAdaptation and EyeAdaptationInverse Shader Nodes in Unreal Engine
    realtimevfx.com
    I came across a post from Beyond-FX about keeping your emissive material the same regardless of the exposure in the game level. The EyeAdaptation node is used in the post. I had encountered the EyeAdaptationInverse node in the tutorials, but didnt understand how it worked. So I decided to figure out how it works and whats the difference.What is Eye Adaptation?Eye Adaptation (also known as Auto Exposure) simulates how the human eye adjusts to different lighting conditions. When you move from a bright area to a dark one, the scene temporarily looks darker until your eyes adjust, simulating real-life vision. And vice versa. As in the example belowWhere to Configure ItYou can turn on/off and modify Eye Adaptation in Project Settings (Check the Auto Exposure to turn on)or edit in the Post Process Volume (that you need to add to the scene; the Auto Exposure from the project settings must be enabled) adjust speed, compensation, and brightness limits to control how your scene transitions between light and dark.P.S. In Unreal Engine, in order for Post Process Volume to apply effects to the entire scene (regardless of its size), you need to enable the Infinite Extent (Unbound) option.To keep the post-processing effects but TURN OFF the Eye Adaptation effect, in Exposure set Min EV100 and Max EV100 to 0.EyeAdaptation, EyeAdaptationInverse shader nodesI created a project, Auto Exposure is turned on, NO Post Process Volume.Created a simple debug material with Emissive 10, Translucent, Unlit.As a result, our Emissive value is always 10. BUT! We see that in the shadow the white circle becomes lighter, and in the light it becomes darker. This is because Auto-Exposure (Eye-adaptation) is enabled.Lets multiply our value of 10 with EyeAdaptation nodeWe see that the values have now been multiplied by ten, in the light emissive = 100, in the shade = 300Now lets divide Emissive (10) by EyeAdaptation, i.e. use the technique from the Beyond-fx post.We see that our Emissive values get smaller in the shadows (around 0.3) and larger in the light (around 1.2). BUT! Our white circle has the same Emissive.Lets use the EyeAdaptationInverse nodeAs we can see the result is the sameConclusion: Dividing Emissive (10) by EyeAdaptation and putting Emissive (10) in EyeAdaptationInverse = the same result = a constant brightness everywhere (The fact that the emissive numbers change is not important; we only care about our white circle.)But what happens if you split EyeAdaptation into Emissive (10) the other way around?We see that our white circle gets lighter in the shadows and darker in the light, but 10 times less than when we multiply EyeAdaptation by Emissive in Example 1.To summarize:Auto Exposure, Eye Adaptation simulates how the human eye adjusts to different lighting conditionsEyeAdaptation; EyeAdaptationInverse nodes = its a NUMBER varying with a scene lighting, if auto-exposure works.EyeAdaptation = Lighter in the shadows, darker in the light.Use EyeAdaptationInverse or divide an Emissive value by EyeAdaptation, if you want a constant brightness on any level and any auto-exposure settings.Homework: create nodes where your effect will lighten in the light and darken in the shade (honestly, I dont understand how to do it myself)
