From its halo-like orbit nearly a million miles from Earth, the James Webb Space Telescope is seeing farther than human eyes have ever seen.

In May, astronomers announced that Webb detected the most distant galaxy found so far, a fuzzy blob of red light that we see as it existed just 290 million years after the Big Bang. Light from this galaxy, several hundreds of millions of times the mass of the Sun, traveled more than 13 billion years until photons fell onto Webb's gold-coated mirror.

A few months later, in July, scientists released an image Webb captured of a planet circling a star slightly cooler than the Sun nearly 12 light-years from Earth. The alien world is several times the mass of Jupiter and the closest exoplanet to ever be directly imaged. One of Webb's science instruments has a coronagraph to blot out bright starlight, allowing the telescope to resolve the faint signature of a nearby planet and use spectroscopy to measure its chemical composition.

Conspiracy theories about missing votes—which are not, in fact, missing—and something being “not right” are being spread widely on X in the wake of Donald Trump’s election victory.

Thanks to Elon Musk’s influence, the president-elect has waffled on the future of America’s electric transition.

Kids and teens can make some pretty hairbrained choices sometimes. But when a kid's choice is to engage in a TikTok challenge that threatens their life, psychiatrists can struggle to understand if it was just an exasperating poor choice born out of impulsivity and immaturity or something darker—an actual suicide attempt.

In a Viewpoint published today in JAMA Psychiatry, two psychiatrists from the University of Tennessee Health Science Center at Memphis raise the alarm about the dangers and complexities of TikTok challenges. They're an "emerging public health concern" for kids, the psychiatrists write, and they're blurring the lines between unintentional injuries and suicide attempts in children and teens.

The child and adolescent psychiatrists Onomeasike Ataga and Valerie Arnold say that their psychiatry team first saw injuries from TikTok challenges during the COVID-19 pandemic, but the trend has continued since the pandemic eased. Over recent years, they've seen children and teens hospitalized from a variety of challenges, including the "blackout challenge," in which participants attempt to choke themselves until they pass out; the "Benadryl challenge," in which participants ingest a large amount of the allergy medicine to get high and hallucinate; and the "fire challenge," in which participants pour a flammable liquid on their body and light it on fire. In these cases, the psychiatry team is sometimes called in to help assess whether the children and teens had an intent to self-harm. It's often hard to determine—and thus hard to decide on treatment recommendations.

A few weeks before the US presidential election, Donald Trump suggested that a breakup of Google's search business may not be an appropriate remedy to destroy the tech giant's search monopoly.

"Right now, China is afraid of Google," Trump said at a Chicago event. If that threat were dismantled, Trump suggested, China could become a greater threat to the US, because the US needs to have "great companies" to compete.

Trump's comments came about a week after the US Department of Justice proposed remedies in the Google monopoly trial, including mulling a breakup.

Prediction markets like Kalshi beat pollsters in forecasting the 2024 US election. Mansour now says financial marketplaces are the future of political prognostication.

Early Wednesday morning, Donald Trump became the presumptive winner of the 2024 US presidential election, setting the stage for dramatic changes to federal AI policy when he takes office early next year. Among them, Trump has stated he plans to dismantle President Biden's AI Executive Order from October 2023 immediately upon taking office.

Biden's order established wide-ranging oversight of AI development. Among its core provisions, the order established the US AI Safety Institute (AISI) and lays out requirements for companies to submit reports about AI training methodologies and security measures, including vulnerability testing data. The order also directed the Commerce Department's National Institute of Standards and Technology (NIST) to develop guidance to help companies identify and fix flaws in their AI models.

Trump supporters in the US government have criticized the measures, as TechCrunch points out. In March, Representative Nancy Mace (R-S.C.) warned that reporting requirements could discourage innovation and prevent developments like ChatGPT. And Senator Ted Cruz (R-Texas) characterized NIST's AI safety standards as an attempt to control speech through "woke" safety requirements.

The crypto industry is celebrating the return of Donald Trump to the White House in anticipation of an easier ride under his regime.

The crypto industry is celebrating the return of Donald Trump to the White House in anticipation of an easier ride under his regime.

On the ground, the Trump campaign was at a disadvantage to Kamala Harris’s massive canvassing operations. But many misunderstood the power—and purpose—of influencer marketing campaigns.

Whew—the big event is finally behind us. I'm talking, of course, about the Ars Technica version 9 redesign, which we rolled out last month in response to your survey feedback and which we have iterated on extensively in the weeks since. The site is now fully responsive and optimized for mobile browsing, with a sleek new look and great user options.

In response to your comments, our tireless tech and design team of Jason and Aurich have spent the last few weeks adding a font size selector, tweaking the default font and headline layout, and adding the option for orange hyperlinks. Plus, they rolled out an all-new, subscriber-only "wide mode" for Ars superfans who need 100+ character line lengths in their lives. Not enough? Jason and Aurich also tweaked the overall information density (especially on mobile), added next/previous story buttons to articles, and made the nav bar "sticky" on mobile, all in response to your feedback. (Read more about our two post-launch rounds of updates here and here.)

If that's still not enough site goodness, Jason and Aurich are currently locked in their laboratory, cooking up a brand-new "true light" theme and big improvements to commenting and comment voting.

This updated Sony console delivers better graphics but at a perhaps unreasonably high cost.

Less than a month has passed since the historic fifth flight of SpaceX's Starship, during which the company caught the booster with mechanical arms back at the launch pad in Texas. Now, another test flight could come as soon as Nov. 18, the company announced Wednesday.

The improbable but successful recovery of the Starship first stage with "chopsticks" last month, and the on-target splashdown of the Starship upper stage halfway around the world, allowed SpaceX to avoid an anomaly investigation by the Federal Aviation Administration. Thus, the company was able to press ahead on a sixth test flight if it flew a similar profile.

And that's what SpaceX plans to do, albeit with some notable additions to the flight plan.

More than two years after a historic Supreme Court decision ended the national right to an abortion, some states are fighting back—but the future of abortion rights remains in doubt.

The European Commission (EC) has opened an antitrust investigation into US-based glass-maker Corning, claiming that its Gorilla Glass has dominated the mobile phone screen market due to restrictive deals and licensing.

Corning's shatter-resistant alkali-aluminosilicate glass keeps its place atop the market, according to the EC's announcement, because it both demands, and rewards with rebates, device makers that agree to "source all or nearly all of their (Gorilla Glass) demand from Corning." Corning also allegedly required device makers to report competitive offers to the glass maker. The company is accused of exerting a similar pressure on "finishers," or those firms that turn raw glass into finished phone screen protectors, as well as demanding finishers not pursue patent challenges against Corning.

"[T]he agreements that Corning put in place with OEMs and finishers may have excluded rival glass producers from large segments of the market, thereby reducing customer choice, increasing prices, and stifling innovation to the detriment of consumers worldwide," the Commission wrote.

Now that the US presidential election has been called for Donald Trump, the sweeping tariffs regime that Trump promised on the campaign trail seems imminent. For the tech industry, already burdened by the impact of tariffs on their supply chains, it has likely become a matter of "when" not "if" companies will start spiking prices on popular tech.

During Trump's last administration, he sparked a trade war with China by imposing a wide range of tariffs on China imports, and President Joe Biden has upheld and expanded them during his term. These tariffs are taxes that Americans pay on restricted Chinese goods, imposed by both presidents as a tactic to punish China for unfair trade practices, including technology theft, by hobbling US business with China.

As the tariffs expanded, China has often retaliated, imposing tariffs on US goods and increasingly limiting US access to rare earth materials critical to manufacturing a wide range of popular products. And any such retaliation from China only seems to spark threats of more tariffs in the US—setting off a cycle that seems unlikely to end with Trump imposing a proposed 60 percent tax on all China imports. Experts told Ars that the tech industry expects to be stuck in the middle of the blow-by-blow trade war, taking punches left and right.
