Chris Krebs, who debunked 2020 election lies, vows full-time fight against Trump
Chris Krebs, the former Cybersecurity and Infrastructure Security Agency (CISA) director who was fired by President Trump in 2020 and targeted in a Trump order last week, said he left his job at a security company in order to focus on fighting back against the Trump administration.
Trump fired Krebs in November 2020 when the then-CISA chief disputed Trump's baseless claims that the 2020 election was rigged against him. Krebs was until this week the chief intelligence and public policy officer for security vendor SentinelOne. Krebs and SentinelOne were both targeted by Trump in an April 9 presidential memorandum titled, "Addressing Risks from Chris Krebs and Government Censorship."
The Trump order called Krebs "a significant bad-faith actor who weaponized and abused his Government authority" and whose "misconduct involved the censorship of disfavored speech implicating the 2020 election and COVID-19 pandemic."
Google is gifting a year of Gemini Advanced to every college student in the US
Google CEO Sundar Pichai has reportedly set a goal for the company to reach 500 million Gemini users before the end of 2025. Rolling out new models may help the company get there, but you know what else helps? Giving away premium features for free. Google has announced today that it's giving all US college students free access to Gemini Advanced, and not just for a month or two—the offer is good for a full year of service.
With Gemini Advanced, you get access to the more capable Pro models, as well as unlimited use of the Deep Research tool based on it. Subscribers also get a smattering of other AI tools, like the Veo 2 video generator, NotebookLM, and Gemini Live. The offer is for the Google One AI Premium plan, so it includes more than premium AI models, like Gemini features in Google Drive and 2TB of Drive storage.
Google has a new landing page for the deal, allowing eligible students to sign up for their free Google One AI Premium plan. The offer is valid from now until June 30. Anyone who takes Google up on it will enjoy the free plan through spring 2026. The company hasn't specified an end date, but we would wager it will be June of next year. Google's intention is to give students an entire school year of Gemini Advanced from now through finals next year. At the end of the term, you can bet Google will try to convert students to paying subscribers.
Google loses ad tech monopoly trial, faces additional breakups
The verdict is in, and Google has been found to illegally hold online ad tech monopolies.
For over a decade, "Google has willfully engaged in a series of anticompetitive acts to acquire and maintain monopoly power in the publisher ad server and ad exchange markets for open-web display advertising," tying its publisher ad server and ad exchange together "to establish and protect its monopoly power in these two markets," the ruling said.
At trial, the DOJ argued that Google's ad business expanded to choke out competitors and benefit only Google. They argued that Google "rigged" ad auctions, allegedly controlling "multiple parts" of services used to place ads all over the Internet, unfairly advantaging itself in various markets.
Sony releases new trailer for 28 Years Later
The critically acclaimed 2002 film 28 Days Later is often credited with sparking the 21st-century revival of the zombie genre. Director Danny Boyle is back with more zombie-virus dystopian horror in his new film set in the same fictional world, 28 Years Later—not so much a direct sequel but the start of a new planned trilogy.
(Some spoilers for 28 Days Later and 28 Weeks Later below.)
In 28 Days Later, a highly contagious "Rage Virus" is accidentally released from a lab in Cambridge, England. Those infected turn into violent, mindless monsters who brutally attack the uninfected—so-called "fast zombies." Transmitted by bites, scratches, or even just by getting a drop of infected blood in one's mouth, the virus spreads rapidly, effectively collapsing society. A bicycle courier named Jim (Cillian Murphy) awakens from a coma 28 days later to find London mostly deserted, apart from a handful of survivors fleeing the infected hordes, and joins them in the pursuit of safety. Jim (barely) survives, and we see zombies dying of starvation in the streets during the denouement.
What do you actually do in Mario Kart World’s vast open world?
Earlier this month, Nintendo let Ars Technica and other outlets have access to a small hands-on slice of Mario Kart World ahead of its planned June 5 launch. Today, a short livestreamed video presentation gave a bit of extra information about how exactly the full version of the free-roaming Nintendo Switch 2 launch game will work in practice.
As the name implies, Mario Kart World sets itself apart from previous games via a "vast interconnected world" that you can roam freely between the actual race courses. That open space between races will feature "hundreds of P-switches," Nintendo said, each of which activates a small mission to "hone your driving abilities." Free-roaming racers will also be able to find hidden medallions and question-mark panels, as well as "drive-thru" food items that can be used to unlock new outfits.
"Hundreds" of P-Switches like this will activate short missions throughout the game's world. Credit: NintendoWhile cruising around the Mario Kart "world," players will stumble onto new courses "inspired by their surrounding region," as well as "nostalgic courses for past titles... reimagined and spread throughout the world." When playing in Grand Prix mode, the drive between these courses will be integrated into the usual four-course cups themselves; after racing Mario Kart Circuit in the Mushroom cup, for instance, the second race "will have you covering the distance from Mario Bros. Circuit to Crown City," Nintendo said.
Tesla odometer uses “predictive algorithms” to void warranty, lawsuit claims
Tesla is facing a new scandal that once again sees the electric automaker accused of misleading customers. In the past, it has been caught making "misleading statements" about the safety of its electric vehicles, and more recently, an investigation by Reuters found Tesla EVs exaggerated their efficiency. Now, a lawsuit filed in California alleges that the cars are also falsely exaggerating odometer readings to make warranties expire prematurely.
The lead plaintiff in the case, Nyree Hinton, bought a used Model Y with less than 37,000 miles (59,546 km) on the odometer. Within six months, it had pushed past the 50,000-mile (80,467 km) mark, at which point the car's bumper-to-bumper warranty expired. (Like virtually all EVs, Tesla powertrains have a separate warranty that lasts much longer.)
For this six-month period, Hinton says his Model Y odometer gained 13,228 miles (21,288 km). By comparison, averages of his three previous vehicles showed that with the same commute, he was only driving 6,086 miles (9,794 km) per 6 months.
Diablo vs. Darkest Dungeon: RPG devs on balancing punishment and power
It’s one of the oldest conversations in gaming. Do you play video games because you’re looking for a challenge and want to experience the thrill and satisfaction of overcoming obstacles? Or do you turn to games to feel empowered, for the escapist fantasy of possessing incredible abilities that are often unattainable in real life?
Nowhere is this question more relevant than in the role-playing game genre. The core of the genre is developing a character (or stable of characters) over time, watching their power grow and capabilities expand. Satisfying player power fantasies is at the heart of many RPGs, where you can watch your virtual avatar grow from an unknown serf clad in rags to a living god, wielding incredible power to dominate your enemies or redeem a broken world.
That said, the thrill of power is only really exciting when leavened with a little friction. Eventually, even being omnipotent gets old.
Climate change will make rice toxic, say researchers
Rice, the world’s most consumed grain, will become increasingly toxic as the atmosphere heats and as carbon dioxide emissions rise, potentially putting billions of people at risk of cancers and other diseases, according to new research published Wednesday in The Lancet.
Eaten every day by billions of people and grown across the globe, rice is arguably the planet’s most important staple crop, with half the world’s population relying on it for the majority of its food needs, especially in developing countries.
But the way rice is grown—mostly submerged in paddies—and its highly porous texture mean it can absorb unusually high levels of arsenic, a potent carcinogenic toxin that is especially dangerous for babies.
OpenAI releases new simulated reasoning models with full tool access
On Wednesday, OpenAI announced the release of two new models—o3 and o4-mini—that combine simulated reasoning capabilities with access to functions like web browsing and coding. These models mark the first time OpenAI's reasoning-focused models can use every ChatGPT tool simultaneously, including visual analysis and image generation.
OpenAI announced o3 in December, and until now, only less-capable derivative models named "o3-mini" and "03-mini-high" have been available. However, the new models replace their predecessors—o1 and o3-mini.
OpenAI is rolling out access today for ChatGPT Plus, Pro, and Team users, with Enterprise and Edu customers gaining access next week. Free users can try o4-mini by selecting the "Think" option before submitting queries. OpenAI CEO Sam Altman tweeted, "we expect to release o3-pro to the pro tier in a few weeks."
Why are two Texas senators trying to wrest a Space Shuttle from the Smithsonian?
Should the city of Houston, which proudly bills itself as "Space City," have a prized Space Shuttle orbiter on public display?
More than a decade ago, arguably, the answer was yes. After all, the Space Shuttle program was managed from Johnson Space Center, in southeastern Houston. All the astronauts who flew on the shuttle trained there. And the vehicle was operated out of Mission Control at the Houston-based facility.
But when the final decisions were being made to distribute the shuttles 15 years ago, the Houston community dragged its feet on putting together a competitive proposal. There were also questions about the ability of Space Center Houston to raise funding to house the shuttle within a new display area, which magnified concerns that the historical vehicle, like a Saturn V rocket before it, would be left outside in the region's humid environment. Finally, other cities offered better proposals for displaying the shuttles to the public.
AP: Trump admin to kill IRS free tax-filing service that Intuit lobbied against
The Trump administration plans to kill the free tax filing program operated by the Internal Revenue Service, the Associated Press reported today, citing two anonymous sources.
The IRS launched Direct File in a pilot for the 2024 tax filing season. It was available to taxpayers in 12 states last year and was available in 25 states this year. The program's website says the filing tool will be open until October 15 for people who obtained deadline extensions, but it hasn't been updated to account for the plan to end Direct File.
"The program had been in limbo since the start of the Trump administration as Elon Musk and the Department of Government Efficiency have slashed their way through the federal government," the AP article said. "Musk posted in February on his social media site, X, that he had 'deleted' 18F, a government agency that worked on technology projects such as Direct File."
Disgruntled users roast X for killing Support account
After X (formerly Twitter) announced it would be killing its "Support" account, disgruntled users quickly roasted the social media platform for providing "essentially non-existent" support.
"We'll soon be closing this account to streamline how users can contact us for help," X's Support account posted, explaining that now, paid "subscribers can get support via @Premium, and everyone can get help through our Help Center."
On X, the Support account was one of the few paths that users had to publicly seek support for help requests the platform seemed to be ignoring. For suspended users, it was viewed as a lifeline. Replies to the account were commonly flooded with users trying to get X to fix reported issues, and several seemingly paying users cracked jokes in response to the news that the account would soon be removed.
LG TVs’ integrated ads get more personal with tech that analyzes viewer emotions
LG TVs will soon leverage an AI model built for showing advertisements that more closely align with viewers' personal beliefs and emotions. The company plans to incorporate a partner company’s AI tech into its TV software in order to interpret psychological factors impacting a viewer, such as personal interests, personality traits, and lifestyle choices. The aim is to show LG webOS users ads that will emotionally impact them.
The upcoming advertising approach comes via a multi-year licensing deal with Zenapse, a company describing itself as a software-as-a-service marketing platform that can drive advertiser sales “with AI-powered emotional intelligence.” LG will use Zenapse’s technology to divide webOS users into hyper-specific market segments that are supposed to be more informative to advertisers. LG Ad Solutions, LG’s advertising business, announced the partnership on Tuesday.
The technology will be used to inform ads shown on LG smart TVs’ homescreens, free ad-supported TV (FAST) channels, and elsewhere throughout webOS, per StreamTV Insider. LG will also use Zenapse's tech to “expand new software development and go-to-market products," it said. LG didn’t specify the duration of its licensing deal with Zenapse.
14 reasons why Trump’s tariffs won’t bring manufacturing back
On April 2, 2025, our president announced major new taxes on imports from foreign countries (“tariffs”), ranging from 10 percent to 49 percent. The stated goal is to bring manufacturing back to the United States and to “make America wealthy again.”
These tariffs will not work. In fact, they may even do the opposite, fail to bring manufacturing back, and make America poorer in the process.
This article gives the 14 reasons why this is the case, how the United States could bring manufacturing back if it were serious about doing so, and what will ultimately happen with this wrongheaded policy.
Government IT whistleblower calls out DOGE, says he was threatened at home
A government whistleblower told lawmakers that DOGE's access to National Labor Relations Board (NLRB) systems went far beyond what was needed to analyze agency operations and apparently led to a data breach. NLRB employee Daniel Berulis, a DevSecOps architect, also says he received a threat when he was preparing his whistleblower disclosure.
"Mr. Berulis is coming forward today because of his concern that recent activity by members of the Department of Government Efficiency ('DOGE') have resulted in a significant cybersecurity breach that likely has and continues to expose our government to foreign intelligence and our nation's adversaries," said a letter from the group Whistleblower Aid to the Senate Select Committee on Intelligence leaders and the US Office of Special Counsel.
The letter, Berulis' sworn declaration, and an exhibit with screenshots of technical data are available here. "This declaration details DOGE activity within NLRB, the exfiltration of data from NLRB systems, and—concerningly—near real-time access by users in Russia," Whistleblower Aid Chief Legal Counsel Andrew Bakaj wrote. "Notably, within minutes of DOGE personnel creating user accounts in NLRB systems, on multiple occasions someone or something within Russia attempted to login using all of the valid credentials (e.g. Usernames/Passwords). This, combined with verifiable data being systematically exfiltrated to unknown servers within the continental United States—and perhaps abroad—merits investigation."
RoboBee sticks the landing
Several years ago, Harvard University roboticist Robert Wood made headlines when his lab constructed RoboBee, a tiny robot capable of partially untethered flight. Over the years, RoboBee has learned to fly, dive, and hover. The latest improvement: RoboBee has learned how to stick the landing, thanks to biomechanical improvements to its landing gear modeled on the crane fly, which has a similar wingspan and body size to the RoboBee platform. The details of this achievement appear in a new paper published in the journal Science Robotics.
As previously reported, the ultimate goal of the RoboBee initiative is to build a swarm of tiny interconnected robots capable of sustained, untethered flight—a significant technological challenge, given the insect-sized scale, which changes the various forces at play. In 2019, Wood's group announced its achievement of the lightest insect-scale robot so far to have achieved sustained, untethered flight—an improved version called the RoboBee X-Wing. In 2021, Wood's group turned its attention to the biomechanics of the mantis shrimp's knock-out punch and built a tiny robot to mimic that movement.
But RoboBee was not forgotten, with the team focusing this time around on achieving more robust landings. “Previously, if we were to go in for a landing, we’d turn off the vehicle a little bit above the ground and just drop it, and pray that it will land upright and safely,” said co-author Christian Chan, one of Wood's graduate students. The trick is to minimize velocity when approaching a surface and then quickly dissipating impact energy. Even something as small and light as RoboBee can generate significant impact energy. The crane fly has long, jointed appendages that enable them to dampen their landings, so the insect served as a useful model for RoboBee's new landing gear.
What happened when Formula E visited an American oval track?
MIAMI—A decade after its first visit to the state, Formula E returned to Florida this past weekend. The even has come a long way since that first chaotic Miami ePrix: The cars are properly fast now, the racing is both entertaining and quite technical, and at least the trackside advertising banners were in place before the start of the event this time.
It's not the same track, of course. Nor is it anywhere near the Hard Rock Stadium that Formula 1 now fills with ersatz marinas and high-priced hospitality packages during its visit to the area. Despite what the b-roll helicopter shots might have led viewers to believe, we were actually an hour south of the city at a mid-sized oval track next to a landfill in Homestead. Usually, a place that hosts NASCAR races, for Formula E, there was a 2.2-mile (3.5 km) layout that used the straights and infield but not the banked corners.
Formula E has begun to branch out from its original diet of racing exclusively on temporary city center street tracks, having visited Portland International Raceway in Oregon in 2023 and 2024. Despite the bucolic charm of PIR, with its easy bicycle and light rail access, enthusiastic crowd of attendees, and exciting racing, it was only a temporary patch for Formula E. The vast majority of Formula E's fans live outside the US, and Portland means nothing to them, but they've heard of Miami, I was told last year.
CDC struggling to fight raging measles outbreak after deep funding, staff cuts
In now-rarified comments from experts at the Centers for Disease Control and Prevention, an agency official on Tuesday evening said the explosive measles outbreak mushrooming out of West Texas will require "significant financial resources" to control and that the agency is already struggling to keep up.
"We are scrapping to find the resources and personnel needed to provide support to Texas and other jurisdictions," said David Sugerman, the CDC's lead on its measles team. The agency has been devastated by brutal cuts to CDC staff and funding, including a clawback of more than $11 billion in public health funds that largely went to state health departments.
Sugerman noted that the response to measles outbreaks is generally expensive. "The estimates are that each measles case can be $30,000 to $50,000 for public health response work—and that adds up quite quickly." The costs go to various responses, including on-the-ground response teams, vaccine doses and vaccination clinics, case reporting, contact tracing, mitigation plans, infection prevention, data systems, and other technical assistance to state health departments.
Google suspended 39.2 million malicious advertisers in 2024 thanks to AI
Google may have finally found an application of large language models (LLMs) that even AI skeptics can get behind. The company just released its 2024 Ads Safety report, confirming that it used a collection of newly upgraded AI models to scan for bad ads. The result is a huge increase in suspended spammer and scammer accounts, with fewer malicious ads in front of your eyeballs.
While stressing that it was not asleep at the switch in past years, Google reports that it deployed more than 50 enhanced LLMs to help enforce its ad policy in 2024. Some 97 percent of Google's advertising enforcement involved these AI models, which reportedly require even less data to make a determination. Therefore, it's feasible to tackle rapidly evolving scam tactics.
Google says that its efforts in 2024 resulted in 39.2 million US ad accounts being suspended for fraudulent activities. That's over three times more than the number of suspended accounts in 2023 (12.7 million). The factors that trigger a suspension usually include ad network abuse, improper use of personalization data, false medical claims, trademark infringement, or a mix of violations.
Trump threatens to spike chipmakers’ costs by billions as China mulls exemptions
The semiconductor industry is bracing to potentially lose more than $1 billion once Donald Trump announces chip tariffs.
Two sources familiar with discussions between chipmakers and lawmakers last week told Reuters that Applied Materials, Lam Research, and KLA—three of the largest US chip equipment makers—could each lose about "$350 million over a year related to the tariffs." That adds up to likely more than $1 billion in losses between the three, and smaller firms will likely face similarly spiked costs, estimating losses in the tens of millions.
Some chipmakers are already feeling the pain of Trump's trade war, despite a 90-day pause on reciprocal tariffs and a tenuous exception for semiconductors and other electronics.
