Rep. Jeff Jackson of North Carolina has used it to explain the complex fight over raising the debt limit. Rep. Robert Garcia of California has used it to engage with members of the LGBTQ+ community. And Sen. Bob Casey of Pennsylvania has used it to give an overview of Election Day results.

As pressure against TikTok mounts in Washington, the more than two dozen members of Congress — all Democrats — who are active on the social media platform are being pushed by their colleagues to stop using it. Many defend their presence on the platform, saying they have a responsibility as public officials to meet Americans where they are — and more than 150 million are on TikTok.

“I’m sensitive to the ban and recognize some of the security implications. But there is no more robust and expeditious way to reach young people in the United States of America than TikTok,” Democratic Rep. Dean Phillips of Minnesota told The Associated Press.

Yet the lawmakers active on TikTok remain a distinct minority. Most in Congress are in favor of limiting the app, forcing a sale to remove connections to China or even banning it outright. The US armed forces and more than half of US states have already banned the app from official devices, as has the federal government. Similar bans have been imposed in Denmark, Canada, Great Britain and New Zealand, as well as the European Union.

Criticism of TikTok reached a new level last week as CEO Shou Zi Chew testified for more than six hours at a contentious hearing in the House. Lawmakers grilled Chew about the implications of the app for America's national security and the effect on the mental health of its users. And the tough questions came from both sides of the aisle, as Republicans and Democrats alike pressed Chew about TikTok’s content moderation practices, its ability to shield American data from Beijing and its spying on journalists.

“I've got to hand it to you," said Rep. August Pfluger, R-Texas, as members questioned Chew over data security and harmful content. “You’ve actually done something that in the last three to four years has not happened except for the exception of maybe (Russian President) Vladimir Putin. You have unified Republicans and Democrats.”

While the hearing made plain that lawmakers view TikTok as a threat, their lack of first-hand experience with the app was apparent at times. Some made inaccurate and head-scratching comments, seemingly not understanding how TikTok connects to a home Wi-Fi router or how it moderates illicit content.

Rep. Mark Pocan, D-Wis., who is active on the app and opposes a nationwide ban, called the hearing “cringeworthy."

“It was just so painful to watch,” he told the AP on Friday. “And it just shows the real problem is Congress doesn’t have a lot of expertise, whether it be social media or, for that matter, more importantly, technology.”

Garcia, who said he uses TikTok more as a consumer, said most of his colleagues who are proposing a nationwide ban told him they had never used the app. “It gets hard to understand if you’re not actually on it,” the freshman Democrat said. “And at the end of the day, a lot of TikTok is harmless people dancing and funny videos.”

“It’s also incredibly rich educational content, and learning how to bake and learning about the political process,” he said.

Rep. Jamaal Bowman, D-N.Y., who has more than 180,000 followers on the app, held a news conference with TikTok influencers before the hearing. He accused Republicans of pushing a ban on TikTok for political reasons.

“There are 150 million people on TikTok and we are more connected to them than Republicans are,” Bowman said. “So for them, it’s all about fear-mongering and power. It’s not TikTok, because, again, we’ve looked the other way and allowed Facebook and other platforms to do similar things.”

Critics of TikTok in Congress say their opposition is rooted in national security, not politics. TikTok is a wholly owned subsidiary of Chinese technology firm ByteDance Ltd., which appoints its executives. They worry Chinese authorities could force ByteDance to hand over TikTok data on American users, effectively turning the app into a data-mining operation for a foreign power. The company insists it is taking steps to make sure that can never happen.

“The basic approach that we’re following is to make it physically impossible for any government, including the Chinese government, to get access to US user data,” general counsel Erich Andersen said during an interview with the AP on Friday at a cybersecurity conference in California.

TikTok has been emphasizing a $1.5 billion proposal to store all US user data on servers owned and maintained by the software giant Oracle. Access to US data would be managed by US employees through a separate entity run independently of ByteDance and monitored by outside observers.

Republican Sen. Thom Tillis of North Carolina took the unusual step of releasing a public statement urging all members of Congress to stop using TikTok, including from his home state — seemingly a jab at Jackson, who is one of the more active members with more than 1.8 million followers.

“I was just saying if we’re having a discussion about TikTok then I think we ought to at least reduce the pull factor by elected officials who can simply come off of it,” Tillis said this week, when asked about his statement. “I don’t have a TikTok account. So that was an easy separation for me.”

Loud warnings about TikTok have also been coming from President Joe Biden's administration. Secretary of State Antony Blinken and FBI Director Christopher Wray have told Congress in recent weeks that TikTok is a national security threat. Blinken told lawmakers the threat “should be ended one way or another."

But some members are unconvinced.

“It’s like turning your cell phone off on an airplane. You’re supposed to do. And if it was super dangerous, I don’t think we will be allowed to have the phone on the plane,” Rep. Greg Landsman, D-Ohio, said Wednesday, “So if it was super dangerous for members of Congress to have this app on their phone, you have to imagine the administration or our government would say absolutely not, you can’t have it on a government phone.”

Concerns about what kind of content Americans encounter online, or how their data is collected by technology companies, also aren’t new. Congress has been wanting to curtail the amount of data tech companies collect on consumers through a national privacy law, but those efforts have stalled repeatedly over the years.

Supporters of TikTok on Capitol Hill are urging their colleagues to educate themselves about social media as a whole so Congress can pass legislation that deals with broader issues of data privacy, instead of hyper-focusing on a ban of TikTok, which could risk political backlash and a court fight over the reach of the First Amendment.

“We are uninformed and misinformed. We don’t even understand how social media works. We don’t know anything about data brokers and how data brokers sell our data to foreign countries and foreign companies right now,” Bowman said. “So ban TikTok tomorrow, this stuff is still going to be happening.”

AI to Track Icebergs Adrift at Sea in Boon for Science

British scientists said Thursday that a world-first AI tool to catalogue and track icebergs as they break apart into smaller chunks could fill a "major blind spot" in predicting climate change.

Icebergs release enormous volumes of freshwater when they melt on the open water, affecting global climate patterns and altering ocean currents and ecosystems, reported AFP.

But scientists have long struggled to keep track of these floating behemoths once they break into thousands of smaller chunks, their fate and impact on the climate largely lost to the seas.

To fill in the gap, the British Antarctic Survey has developed an AI system that automatically identifies and names individual icebergs at birth and tracks their sometimes decades-long journey to a watery grave.

Using satellite images, the tool captures the distinct shape of icebergs as they break off -- or calve -- from glaciers and ice sheets on land.

As they disintegrate over time, the machine performs a giant puzzle problem, linking the smaller "child" fragments back to the "parent" and creating detailed family trees never before possible at this scale.

It represents a huge improvement on existing methods, where scientists pore over satellite images to visually identify and track only the largest icebergs one by one.

The AI system, which was tested using satellite observations over Greenland, provides "vital new information" for scientists and improves predictions about the future climate, said the British Antarctic Survey.

Knowing where these giant slabs of freshwater were melting into the ocean was especially crucial with ice loss expected to increase in a warming world, it added.

"What's exciting is that this finally gives us the observations we've been missing," Ben Evans, a machine learning expert at the British Antarctic Survey, said in a statement.

"We've gone from tracking a few famous icebergs to building full family trees. For the first time, we can see where each fragment came from, where it goes and why that matters for the climate."

This use of AI could also be adapted to aid safe passage for navigators through treacherous polar regions littered by icebergs.

Iceberg calving is a natural process. But scientists say the rate at which they were being lost from Antarctica is increasing, probably because of human-induced climate change.

 


AMD Predicts Weaker First-Quarter Sales, Shares Plunge on Nvidia Comparisons

AMD Predicts Weaker First-Quarter Sales, Shares Plunge on Nvidia Comparisons

Advanced Micro Devices on Tuesday forecast a slight decline in quarterly revenue, raising concerns about whether it ​can effectively challenge Nvidia in the booming AI market and sending its shares tumbling 8% in after-hours trade.

The lackluster prediction comes despite an unexpected boost from sales of certain artificial intelligence chips to China, which began in the last quarter after the Trump administration approved a license for orders that AMD received in early 2025.

And without those sales to China which generated $390 million, AMD's data-center segment would have missed estimates for the fourth quarter.

AMD said it expects revenue of about $9.8 billion this quarter, plus or minus $300 million. That's down from $10.27 billion in the fourth-quarter which was up 34% year-on-year and ahead of LSEG ‌estimates for $9.67 billion.

PALES ‌NEXT TO NVIDIA

Though AMD is seen as one of the ‌few ⁠contenders ​that can seriously ‌challenge Nvidia, investors noted the stark contrast between the two companies' performances. AMD expects an adjusted gross margin of 55% this quarter. Nvidia has said it expects adjusted gross margin in the mid-70% range during its fiscal 2027.

"The expectations for large blowout quarters for AI-related hardware companies have skewed what the market is looking for," said Bob O'Donnell, president of TECHnalysis Research.

The forecast for the current first quarter includes $100 million from sales to China, where the situation remains "dynamic," AMD CEO Lisa Su said on a conference call with investors.

The US government ⁠has placed restrictions on the exports of advanced chips to China, but AMD received licenses to sell modified versions of its MI300 series ‌of AI chips there. Its MI308 chip competes with Nvidia's H20 ‍chip in China.

OPENAI SALES

AMD has accelerated its ‍product launches and is moving into selling full AI systems to better compete against Nvidia, which now ‍provides "rack-scale" systems that combine GPUs, CPUs and networking gear.

Last year, it entered into a multi-year deal to supply AI chips to ChatGPT-owner OpenAI, which would bring in tens of billions of dollars in annual revenue and give the startup the option to buy up to roughly 10% of the chipmaker.

Su reiterated on Tuesday that the company ​expects sales of a new flagship AI server to OpenAI and others to rise rapidly in the second half of this year, saying a global memory-chip crunch will not ⁠slow its plans.

"I do not believe that we will be supply-limited in terms of the ramp that we put in place," Su said.

BEYOND OPENAI

As Big Tech and governments across the globe double down on investing in AI hardware, shares in Santa Clara, California-based AMD have doubled since the start of 2025, outperforming a 60% bump in the broader chip index.

But analysts remain concerned that AMD's success remains tied to a handful of customers that rivals such as Nvidia could try to poach. Reuters reported this week that Nvidia made a $20 billion move to hire most of chip startup Groq's founders after OpenAI held chip supply discussions with the startup.

"Growth appears concentrated in large deployments and specific regions, and China shipments are significant enough to influence a quarter," said eMarketer analyst Gadjo Sevilla.

Revenue in AMD's key data-center segment grew 39% to $5.38 billion in the ‌fourth quarter. But excluding sales of the MI308, which is a data-center chip, that revenue would have been $4.99 billion, below estimates of $5.07 billion.

Switch 2 Sales Boost Nintendo Results but Chip Shortage Looms

The runaway success of the Switch 2 console drove up Nintendo's net profit by more than 50 percent in the nine months to December, the Japanese video game giant said Tuesday.

But a global memory chip shortage, created by frenzied demand for artificial intelligence hardware, could push up manufacturing costs.

The Switch 2 became the world's fastest-selling games console after launching to a fan frenzy last summer.

It is the successor to the original Switch, which soared in popularity during the pandemic when games such as "Animal Crossing" struck a chord during long lockdowns.

Both are hybrid devices that can be connected to a TV or used on-the-go.

In April-December, net profit jumped 51.3 percent year-on-year to 358.9 billion yen ($2.3 billion), and revenue nearly doubled on-year to 1.9 trillion yen, Nintendo said.

But the firm kept its annual unit sales target for the Switch 2 steady at 19 million, and also held its full-year net profit forecast of 350 billion yen.

"Nintendo Switch 2 got off to a good start following its launch on June 5 and unit sales continued to grow through the holiday season," the company said.

Nearly 17.4 million Switch 2 devices were sold in the nine-month period, it added.

"Maintaining momentum is certainly a big focus for Nintendo," Krysta Yang of the Nintendo-focused Kit and Krysta Podcast told AFP.

A lack of heavy-hitting first-party new games for the Switch 2 in coming months risks hindering growth, although third-party titles such as "Resident Evil Requiem" should help fill the gap, she said.

Nintendo said Tuesday it planned to release "Mario Tennis Fever" this month and "Pokemon Pokopia" in March.

While the firm is diversifying into hit movies and theme parks, consoles remain the core of its business.

The Switch 1 has now sold 155.37 million units -- overtaking the Nintendo DS console to be its best-selling hardware of all time.

But soaring prices for memory chips, used in gaming consoles as well as phones, laptops and other electronics, will likely be a headwind for the company.

Their prices have been pushed up as chipmakers focus on producing the advanced memory chips in huge demand to power AI data centers.

"Nintendo and other console manufacturers are publicly keeping quiet about the impact of the shortage," gaming industry consultant Serkan Toto told AFP.

But "users can forget the past when consoles always became cheaper in tandem with component costs falling over time", with price hikes potentially on the way in 2026, he said.

Yang said she thought a price increase for the Switch 2 "is not out of the question" but added that Nintendo "would likely exhaust all other options" before doing so.
