  • General purpose AI could lead to array of new risks, experts say in report ahead of AI summit

    General purpose AI could lead to array of new risks, experts say in report ahead of AI summit

    LONDON — Advanced artificial intelligence systems have the potential to create extreme new risks, such as fueling widespread job losses, enabling terrorism or running amok, experts said in a first-of-its-kind international report Wednesday cataloging the range of dangers posed by the technology.

    The International Scientific Report on the Safety of Advanced AI is being released ahead of a major AI summit in Paris next month. The paper is backed by 30 countries including the U.S. and China, marking rare cooperation between the two countries as they battle over AI supremacy, highlighted by Chinese startup DeepSeek stunning the world this week with its budget chatbot in spite of U.S. export controls on advanced chips to the country.

    The report by a group of independent experts is a “synthesis” of existing research intended to help guide officials working on drawing up guardrails for the rapidly advancing technology, Yoshua Bengio, a prominent AI scientist who led the study, told the Associated Press in an interview.

    “The stakes are high,” the report says, noting that while a few years ago the best AI systems could barely spit out a coherent paragraph, now they can write computer programs, generate realistic images and hold extended conversations.

    While some AI harms are already widely known, such as deepfakes, scams and biased results, the report said that “as general-purpose AI becomes more capable, evidence of additional risks is gradually emerging” and risk management techniques are only in their early stages.

    It comes amid warnings this week about artificial intelligence from the Vatican and the group behind the Doomsday Clock.

    The report focuses on general purpose AI, typified by chatbots such as OpenAI’s ChatGPT used to carry out many different kinds of tasks. The risks fall into three categories: malicious use, malfunctions and widespread “systemic” risks.

    Bengio, who with two other AI pioneers won computer science’s top prize in 2019, said the 100 experts who came together on the report don’t all agree on what to expect from AI in the future. Among the biggest disagreements within the AI research community is the timing of when the fast-developing technology will surpass human capabilities across a variety of tasks and what that will mean.

    “They disagree also about the scenarios,” Bengio said. “Of course, nobody has a crystal ball. Some scenarios are very beneficial. Some are terrifying. I think it’s really important for policymakers and the public to take stock of that uncertainty.”

    Researchers delved into the details surrounding possible dangers. AI makes it easier, for example, to learn how to create biological or chemical weapons because AI models can provide step by step plans. But it’s “unclear how well they capture the practical challenges” of weaponizing and delivering the agents, it said.

    General purpose AI is also likely to transform a range of jobs and “displace workers,” the report says, noting that some researchers believe it could create more jobs than it takes away, while others think it will drive down wages or employment rates, though there’s plenty of uncertainty over how it will play out.

    AI systems could also run out of control, either because they actively undermine human oversight or humans pay less attention, the report said.

    However, a raft of factors make it hard to manage the risks, including AI developers knowing little about how their models work, the authors said.

    The paper was commissioned at an inaugural global summit on AI safety hosted by Britain in November 2023, where nations agreed to work together to contain potentially “catastrophic risks.” At a follow-up meeting hosted by South Korea last year, AI companies pledged to develop AI safety while world leaders backed setting up a network of public AI safety institutes.

    The report, also backed by the United Nations and the European Union, is meant to weather changes in governments, such as the recent presidential transition in the U.S., leaving it up to each country to choose how it responds to AI risks. President Donald Trump rescinded former President Joe Biden’s AI safety policies on his first day in office, and has since directed his new administration to craft its own approach. But Trump hasn’t made any move to disband the AI Safety Institute that Biden formed last year, part of a growing international network of such centers.

    World leaders, tech bosses and civil society are expected to convene again at the Paris AI Action Summit on Feb 10-11. French officials have said countries will sign a “common declaration” on AI development, and agree to a pledge on sustainable development of the technology.

    Bengio said the report’s aim was not to “propose a particular way to evaluate systems or anything.” The authors stayed away from prioritizing particular risks or making specific policy recommendations. Instead they laid out what the scientific literature on AI says “in a way that’s digestible by policymakers.”

    “We need to better understand the systems we’re building and the risks that come with them so that we can we can take these better decisions in the future,” he said.

  • Blinken announces aid for Sudan and talks about AI risks at UN Security Council

    Blinken announces aid for Sudan and talks about AI risks at UN Security Council

    UNITED NATIONS — Secretary of State Antony Blinken announced $200 million in humanitarian aid for conflict-torn Sudan during what is likely his final trip to the United Nations while in office.

    With the U.N. Security Council more divided than ever, Blinken led two meetings of the U.N.’s most powerful body on Thursday, capping his engagements with the world body after a tumultuous four years that saw war return to Europe and multiple crises in the Middle East.

    But neither will focus on Russia’s war with Ukraine or the Mideast, where the U.S. has been frequently at odds with permanent members China and Russia and almost always in the minority when it comes to Israel’s war against Hamas in Gaza.

    Instead, in an apparent bid to produce a modicum of consensus, Blinken is leading Security Council sessions on artificial intelligence and Sudan, where conflict has sparked a dire humanitarian crisis that aid agencies say has not received enough attention.

    The money announced by Blinken will for food, shelter and health care for people Sudan. He also said the State Department will work with Congress to provide an additional $30 million to elevate civilian voices to help with the transition back to democratic governance.

    Here’s a look at America’s top diplomat at the U.N.:

    Blinken has been appearing in person and virtually before the Security Council since March 2021, just after assuming his position as the Biden administration’s top diplomat.

    In addition to several one-off council meetings, including one in February 2022 shortly before Russia invaded Ukraine, Blinken has gone to New York for a week every September for the annual General Assembly gathering of world leaders.

    The presidency of the Security Council rotates alphabetically every month among its 15 members. This month, it’s the U.S. turn.

    The country holding the presidency almost always organizes several signature events on topics its government chooses. Presidents, prime ministers and foreign ministers often preside at these meetings, which ministers from other council nations are invited to attend.

    Russia and China have blocked all council action condemning the invasion of Ukraine.

    This has led U.S. officials to believe that a session on the topic, especially as President-elect Donald Trump prepares to take office with a stated goal of ending the war immediately, would likely be a waste of time.

    On the Middle East, the U.S. has frequently vetoed council action condemning Israel for its tactics against Hamas in Gaza, leaving it virtually alone at the United Nations in supporting Israel.

    War broke out in Sudan last year between rival generals heading the military and paramilitary forces. The fighting has left tens of thousands dead, forced millions from their homes and pushed a large swath of Sudan’s population to starvation — creating an often forgotten global crisis the U.S. is seeking to spotlight.

    The roughly $230 million in assistance announced Thursday brings total U.S. support to over $2.3 billion since the fighting erupted.

    Sudan “is facing one of the most dire humanitarian crises on the face of the planet,” State Department spokesman Vedant Patel told reporters Wednesday.

    “And so anything we can do to continue to work with partners at the U.N. and otherwise to shed light on that, figure out what ways we can continue to unearth and solidify humanitarian corridors and continue to push for a political solution, that’s absolutely a priority for us and we will continue to use ways to elevate that,” he said.

    The U.S. leads the world in developing AI technology, according to a recently released Stanford University index, and it has been in the forefront of U.N. action on AI.

    In March, the first U.N. resolution on artificial intelligence was adopted by the 193-member General Assembly. Sponsored by the U.S., it gives global support to an international effort to ensure the powerful technology benefits all nations, respects human rights and is “safe, secure and trustworthy.”

    Blinken said AI has the potential to do “tremendous good” but can also pose “tremendous threats to the international peace and security that this council is charged with upholding.”

    He noted that “repressive regimes are using AI-enabled surveillance to target journalists and political dissidents” and that “if algorithms are built into weapon systems, and if they malfunction, they could spark a conflict.”

    “By setting rules of the road for AI we can minimize these risks, we can harness the exceptional promise of this technology,” he said.

    Blinken has represented the U.S. at the Security Council about half a dozen times at meetings ranging from Russia’s invasion of Ukraine to the war in Gaza.

    Russia, like the U.S. and China, is a permanent veto-holding member of the 15-nation council, and both have seats at its horseshoe-shaped table.

    But apart from pointed disagreements during debates, there have been no confrontations or one-on-one meetings between Blinken and Russian diplomats at previous U.N. meetings — and there was none on Thursday.

    Blinken thanked Russian Ambassador Vassily Nebenzia after his remarks — as is custom — even though Nebenzia accused the U.S. of imposing rules on others but not abiding by them. But the Russian envoy agreed that “we cannot allow AI to dominate human beings and human values.”

    It is not unusual for Blinken or other senior U.S. officials to attend international meetings and conferences where Russian officials are present, but interactions are rare.

  • 2024 was big for bitcoin. States could see a crypto policy blitz in 2025 in spite of the risks

    2024 was big for bitcoin. States could see a crypto policy blitz in 2025 in spite of the risks

    HARRISBURG, Pa. — The new year will usher in the bitcoin-friendly administration of President-elect Donald Trump and an expanding lobbying effort in statehouses that, together, could push states to become more open to crypto and for public pension funds and treasuries to buy into it.

    Proponents of the uniquely volatile commodity argue it is a valuable hedge against inflation, similar to gold.

    Many bitcoin enthusiasts and investors are quick to criticize government-backed currencies as prone to devaluation and say increased government buy-in will stabilize bitcoin’s future price swings, give it more legitimacy and further boost an already rising price.

    But the risks are significant. Critics say a crypto investment is highly speculative, with so much unknown about projecting its future returns, and warn that investors should be prepared to lose money.

    Only a couple public pension funds have invested in cryptocurrency and a new U.S. Government Accountability Office study on 401(k) plan investments in crypto, issued in recent days, warned it has “uniquely high volatility” and that it found no standard approach for projecting the future returns of crypto.

    It has already been a landmark year for crypto, with bitcoin hitting $100,000, the U.S. Securities and Exchange Commission approving the first exchange-traded funds that hold bitcoin and crypto enthusiasts being cheered by Trump’s promise to make the United States the “bitcoin superpower” of the world.

    Lawmakers in more states can expect to see bills in 2025 to make them crypto-friendly as analysts say crypto is becoming a powerful lobby, bitcoin miners build new installations and venture capitalists underwrite a growing tech sector that caters to cryptocurrencies.

    Meanwhile, a new crypto-friendly federal government under Trump and Congress could consider legislation from Sen. Cynthia Lummis, R-Wyoming, to create a federal bitcoin reserve on which states can piggyback.

    A bill introduced last month in Pennsylvania’s House of Representatives sought to authorize the state’s treasurer and public pension funds to invest in bitcoin. It went nowhere before the legislative session ended, but it caused a stir.

    “I had a friend who is a rep down the road text me, ‘Oh my god, I’m getting so many emails and phone calls to my office,’ more than he ever did about any other bill,” said the measure’s sponsor, Republican Mike Cabell.

    Cabell — a bitcoin enthusiast who lost his reelection bid — expects his bill to be reintroduced by a colleague. And leaders of bitcoin advocacy group Satoshi Action say they expect bills based on their model bill to be introduced in at least 10 other states next year.

    Keith Brainard, research director for the National Association of State Retirement Administrators, said he doesn’t expect many public pension fund investment professionals, who oversee nearly $6 trillion in assets, to invest in crypto.

    Pension fund professionals take risks they deem to be appropriate, but bitcoin investing has a short track record, might only fit into a niche asset class and may not fit the risk-to-reward profile they seek.

    “There might be a bit of dabbling in bitcoin,” Brainard said. “But it’s difficult to envision a scenario in which pension funds right now are willing to make a commitment.”

    In Louisiana, Treasurer John Fleming helped make the state the first to introduce a system by which people can pay a government agency in cryptocurrencies.

    Fleming said he’s not trying to promote cryptocurrency, but rather sees the step as a recognition that government must innovate and be flexible in helping people make financial transactions with the state. He said he would never invest his money, or the state’s, in crypto.

    Fleming recalled meeting with a bitcoin lobbyist recently and came away unconvinced that bitcoin makes for a good investment.

    “My concern is that at some point it’ll stop growing and then people will want to cash in,” Fleming said. “And when they do, it could tank the value of a bitcoin.”

    In Pennsylvania, Treasury Department officials said they have the authority to decide for themselves if cryptocurrencies meet the agency’s investment standards under state law and don’t need new legislation.

    Still, a highly volatile asset is ill-suited to the agency’s need for predictability, considering it writes millions of checks a year. The overwhelming majority of the roughly $60 billion it invests at any given time is in short-term, conservative investments designed for an investment period of months, officials there said.

    Pension boards, which invest on a 30-year time horizon, may already hold small investments in companies involved in mining, trading and storing cryptocurrencies. But they have been slow to embrace bitcoin.

    That could change, said Mark Palmer, managing director and a senior research analyst at The Benchmark Company in New York.

    Pension boards got investment tools they like this year when the U.S. Securities and Exchange Commission approved the first exchange-traded funds that hold bitcoin and, in October, approved listings of options on those funds, Palmer said.

    Many “are likely in the process of getting up to speed on what it means to invest in bitcoin and kicking the tires, so to speak, and that’s a process that typically takes a while at the institutional level,” Palmer said.

    Several major asset managers like BlackRock, Invesco and Fidelity have bitcoin ETFs.

    In May, the State of Wisconsin Investment Board became the first state to invest when it bought $160 million worth of shares in two ETFs, or about 0.1% of its assets. It later scaled back that investment to $104 million in one ETF, as of Sept. 30. A spokesperson declined to discuss it.

    Michigan’s state investment board later reported about $18 million in bitcoin ETF purchases while a candidate for New Jersey governor, Steven Fulop, said that if elected he would push the state’s pension fund to invest in crypto.

    Fulop, the Democratic mayor of Jersey City, just across the Hudson River from Manhattan, has been preparing for months to buy bitcoin ETF shares for up to 2% of the city’s $250 million employee pension fund.

    “We were ahead of the curve,” Fulop said. “And I think that’s what you’re eventually going to see is this is widely accepted, with regard to exposure in all pension funds, some sort of exposure.”

  • Minimally invasive cardiac surgery: Heart risks for your parents, benefits, lifestyle changes, recovery secrets | Health

    Minimally invasive cardiac surgery: Heart risks for your parents, benefits, lifestyle changes, recovery secrets | Health

    A more recent technique called minimally invasive cardiac surgery aims to lessen the trauma connected to open heart surgery. It has several benefits such as less pain, smaller incisions and quicker recovery periods but before agreeing to get this procedure, there are some important considerations to consider.

    According to a recent study, many patients who undergo heart surgery won't have to take opioids as a pain medication after they get discharged from the hospital.(Unsplash)

    In an interview with HT Lifestyle, Dr Shrirang Ranade, Head Of The Department and Consultant – Cardiothoracic and Vascular Surgeon at Manipal Hospital in Pune’s Baner, shared, “Small 2-3-inch incisions help a surgeon access the heart during minimally invasive cardiac surgery. When MIS surgery is used instead of standard open-heart surgery, it can effectively treat a variety of heart diseases with less discomfort and faster recovery times. Whereas traditional heart surgery, which involves cutting through the breastbone (sternotomy), minimally invasive heart surgery is usually carried out through tiny incisions between the ribs. This approach reduces scarring and speeds up healing. This method can be used for coronary artery bypass, valve replacement or repair, and specific repairs for congenital heart conditions.”

    Overall health and specific heart problems are important considerations for choosing candidature for this type of surgery. Dr Shrirang Ranade revealed, “Not every patient is a candidate for minimally invasive procedures. Factors including the complexity of the heart disease, past cardiac surgeries, and underlying health issues such as obesity or lung conditions can affect the decision. A complete review by a cardiac surgeon is required for choosing the best technique. A shorter hospital stay is one of the key benefits of minimally invasive cardiac surgery. After standard surgery, recovery takes a week or longer, but many patients can return home after a few days. Also, the risk of infection, blood loss, and surgical complications is reduced due to the smaller incisions.”

    The expert cautioned, “However, as with any surgery, there are potential risks. These include bleeding, anesthesia-related responses, or problems with the heart or lungs during the surgery. It is important to go through potential risks and benefits in complete detail with the doctors. Most patients recover from minimally invasive cardiac surgery more quickly, returning to their regular activities in a matter of weeks. However, keeping to a provided treatment plan and making lifestyle modifications will be important for maintaining long-term heart health.”

    Bringing his expertise to the same, Dr Ved Prakash, Senior Consultant and Head – Cardiothoracic and Vascular Surgery at Sarvodaya Hospital in Faridabad’s Sector-8, explained, “Minimally invasive heart surgery (MIHS) involves smaller incisions than traditional open-heart surgery. Surgeons use advanced techniques, including small tools and cameras, to perform complex heart procedures. Common procedures include heart valve repair/replacement, coronary artery bypass, and atrial septal defect closure.”

    Benefits over traditional surgery:

    • Smaller Incisions: Typically, incisions are 3-4 inches compared to the 6-8 inch cuts in traditional surgery.
    • Shorter Recovery Time: Recovery is faster, with many patients resuming normal activities in a few weeks.
    • Less Pain and Scarring: The reduced size of incisions leads to less pain and scarring post-surgery.
    • Lower Risk of Infection: Smaller incisions reduce the risk of infection compared to the larger, open incisions in traditional surgery.

    Risks and complications:

    Dr Ved Prakash said, “Like any surgery, MIHS carries risks such as infection, bleeding, stroke, or irregular heart rhythms. The risk level depends on your health, age and the specific procedure.”

    Who is a candidate?

    According to Dr Ved Prakash, not everyone is a candidate for minimally invasive surgery. Factors such as the complexity of the condition, previous surgeries, or certain health conditions may require traditional open-heart surgery.

    Pre-operative preparation:

    Dr Ved Prakash informed, “You will undergo a series of tests, including blood work, imaging and heart function tests, to ensure you’re fit for surgery.”

    Post-surgery recovery:

    • After surgery, you’ll spend some time in the ICU for monitoring. The hospital stay is generally shorter than with open-heart surgery, often around 3-5 days.
    • Full recovery usually takes about 4-6 weeks. You may need cardiac rehabilitation to improve heart function.

    Lifestyle changes after surgery:

    Dr Ved Prakash concluded, “Even after a successful surgery, maintaining heart health through diet, exercise, and medications (if prescribed) is crucial. Adopting a heart-healthy lifestyle can prevent future heart problems.”

  • Recent whale deaths highlight risks from Antarctica’s booming krill fishery

    Recent whale deaths highlight risks from Antarctica’s booming krill fishery

    MIAMI — Two humpback whales were found dead and another seriously injured this year in huge nets used to collect krill for fishmeal and omega-3 pills near Antarctica, The Associated Press has learned.

    The whale deaths, which have not been previously reported, were discussed during recent negotiations between the U.S., China, Russia and two dozen other countries in which officials failed to make progress on long-debated conservation goals and lifted some fishing limits in the Southern Ocean that have been in place since 2009.

    Taken together, the whale deaths and rollback of the catch limits represent a setback for the remote krill fishery, which has boomed in recent years and is set to expand even further following the acquisition of its biggest harvester, Norway’s Aker BioMarine, by a deep-pocketed American private equity firm.

    AP journalists last year spent more than two weeks in the frigid waters around Antarctica aboard a conservation vessel operated by Sea Shepherd Global to take a rare, up-close look at the world’s southernmost fishery. As part of that investigation, the AP followed the tiny crustacean on its journey from the fragile ecosystem, where it is the main nourishment for whales, to salmon farms in Europe, Canada and Australia, pet food manufacturers in China and a former ice cream factory in Houston that produces 80% of the world’s nutrient-rich krill oil.

    Delegates to the annual meeting in Australia of the Commission for the Conservation of Antarctic Marine Living Resources, or CCAMLR, shared with the AP unpublished reports of the whale deaths on the condition of anonymity because the talks, which ended last week, are not open to the public. Officials at CCAMLR, which was established in 1982 to protect the international waters near Antarctica, didn’t comment.

    Under a conservation agreement developed almost two decades ago, the krill catch has soared: from 104,728 metric tons in 2007 to 424,203 metric tons in 2023 as larger, more sophisticated vessels have joined the chase. So far this year, the catch has jumped to 498,000 metric tons — the highest on record, according to the unpublished reports.

    Although fishing is still below a previously agreed limit and barely 1% of the estimated biomass of 63 million metric tons of krill found in the main Antarctic fishing grounds, direct competition between marine mammals has resulted in whale deaths before.

    But following the first ever recorded entanglements of four humpback whales in 2021 and 2022, Aker BioMarine redesigned its fishing nets, which regularly vacuum up to 500 metric tons of krill per day – the equivalent daily diet for about 150 humpback whales. First, it added a rope barrier to repel large mammals and then, last fall, it developed a second barrier to close a still sizable gap that can threaten whales swimming vertically.

    The new net had not yet been installed when a juvenile humpback was observed dead Jan. 27 on the Antarctic Endurance, the company’s most advanced supertrawler, according to a report presented by Norwegian negotiators at the CCAMLR meeting.

    The reasons behind the second death in May involving another Aker BioMarine ship remain unclear. But two days earlier the ship reported difficulty maneuvering its net and blubber was recovered on the ship’s conveyor belt, suggesting the dead whale had been trapped by the net for some time, the report said.

    A third humpback was hauled alive in late January on a Chilean-flagged vessel, the Antarctic Endeavor, using traditional trawling gear. After the ship’s crew struggled for 40 minutes to cut the net tightly wrapped around the 15-meter-long (15-yard-long) male, the whale, with blood on its tail, was dumped back into the ocean.

    “Upon release it was lethargic and had some injuries from rubbing with the net,” according to a report by Chile’s delegation to the CCAMLR talks that included graphic images of the capture. Although the whale was observed swimming, the capture was considered a mortality event by CCAMLR scientists because the released whale’s injuries were likely to prove fatal.

    Attempts to contact the trawler’s owner, Pesca Chile SA, were unsuccessful.

    A minke whale was also found dead after entangling itself in a buoy line belonging to a South Korean vessel targeting Patagonian toothfish, which is also managed by CCAMLR. It was the first ever whale death recorded in the fishery.

    Pressure on krill stocks is building as a result of surging demand for omega-3 pills taken as dietary supplements, advances in fishing and rising ocean temperatures due to climate change.

    This summer, New York-based American Industrial Partners acquired a majority stake in Aker BioMarine’s feed business with the goal of positioning krill as a premium ingredient for the aquaculture industry, now the source for about half the world’s seafood.

    Webjørn Barstad, CEO of the new company, Aker BioMarine Antarctic, said developing new technologies to mitigate risks of whale mortalities is a top priority. Starting next season, he said, its entire fleet will be equipped with special stretch sensors that will alert the crew when a whale has interacted with the mesh front of a trawler’s net. Underwater cameras may also be used, he said.

    “Our goal is always zero incidents,” Barstad said in an interview. “Hopefully the net will do the job but we will try something else as well.”

    CCAMLR, whose mission is conservation, is tasked with refereeing the fishing industry. But in recent years, progress has stalled due to geopolitical wrangling, especially opposition from China and Russia.

    Coming into the latest meeting, hopes were high that delegates would approve a new management plan to further spread the krill catch and finally adopt a California-sized reserve along the Antarctic Peninsula, a highly sensitive ecosystem. Currently, less than 5% of the Southern Ocean is protected — well behind CCAMLR’s target and not nearly enough to meet a United Nations goal to preserve 30% of the world’s oceans by 2030.

    But a tentative deal fell apart over a last minute proposal by the UK and Australia for an even lower catch limit than the one agreed to during talks over the summer, according to one delegate who spoke to AP. China, objecting to the persistent Western demands, then withdrew its support for the marine reserve and refused to renew the existing management system.

    The result: a 620,000 metric ton catch limit that for 15 years has divvied fishing into four quota areas can now be concentrated into even smaller krill hotspots, some of them teeming with wildlife, including seals and penguins, some already showing signs of stress from competition with fishing, tourism and climate change.

    “The meeting was a huge disappointment, even by the low standards that we’ve come to expect,” said Evan Bloom, who for 15 years, until his retirement from the State Department in 2020, led the U.S. delegation to the annual CCAMLR meeting.

    “Krill is the base of the food chain in Antarctica and fishing for krill must be handled sustainably if the entire ecosystem is to thrive,” said Bloom, adding that in the absence of further action by CCAMLR and given the advances in fishing the “prospects for harming the ecosystem have now increased.”

    Barstad said the krill industry will consider putting its own voluntary limits in place in the absence of an updated CCAMLR framework.

    “Whether it’s a big setback, I’m not so sure,” he said. ”Once you go beyond the emotion and come to terms with the fact that a regulation that had been standing for quite some years now suddenly disappeared, a little bit out of the blue, I think it could create a better atmosphere for discussing how to progress sustainably based on science.”

  • TikTok was aware of risks kids and teens face on its platform, legal document alleges

    TikTok was aware of risks kids and teens face on its platform, legal document alleges

    TikTok was aware that its design features are detrimental to its young users and that publicly touted tools aimed at limiting kids’ time on the site were largely ineffective, according to internal documents and communications exposed in lawsuit filed by the state of Kentucky.

    The details are among redacted portions of Kentucky’s lawsuit that contains the internal communications and documents unearthed during a more than two year investigation into the company by various states across the country.

    Kentucky’s lawsuit was filed this week, alongside separate complaints brought forth by attorneys general in a dozen states as well as the District of Columbia. TikTok is also facing another lawsuit from the Department of Justice and is itself suing the Justice Department over a federal law that could ban it in the U.S. by mid-January.

    The redacted information — which was inadvertently revealed by Kentucky’s attorney general’s office and first reported by Kentucky Public Radio — touches on a range of topics, most importantly the extent to which TikTok knew how much time young users were spending on the platform and how sincere it was when rolling out tools aimed at curbing excessive use.

    Beyond TikTok use among minors, the complaint alleges the short-form video sharing app has prioritized “beautiful people” on its platform and has noted internally that some of the content-moderation metrics it has publicized are “largely misleading.”

    The unredacted complaint, which was seen by The Associated Press, was sealed by a Kentucky state judge on Wednesday after state officials filed an emergency motion to seal it.

    When reached for comment, TikTok spokesperson Alex Haurek said: “It is highly irresponsible of the Associated Press to publish information that is under a court seal. Unfortunately, this complaint cherry-picks misleading quotes and takes outdated documents out of context to misrepresent our commitment to community safety.”

    “We have robust safeguards, which include proactively removing suspected underage users, and we have voluntarily launched safety features such as default screentime limits, family pairing, and privacy by default for minors under 16,” Haurek said in a prepared statement. “We stand by these efforts.”

    The complaint alleges that TikTok has quantified how long it takes for young users to get hooked on the platform, and shared the findings internally in presentations aimed at increasing user-retention rates. The “habit moment,” as TikTok calls it, occurs when users have watched 260 videos or more during the first week of having a TikTok account. This can happen in under 35 minutes since some TikTok videos run as short as 8 seconds, the complaint says.

    Kentucky’s lawsuit also cites a spring 2020 presentation from TikTok that concluded that the platform had already “hit a ceiling” among young users. At that point, the company’s estimates showed at least 95% of smartphone users under 17 used TikTok at least monthly, the complaint notes.

    TikTok tracks metrics for young users, including how long young users spend watching videos and how many of them use the platform every day. The company uses the information it gleans from these reviews to feed its algorithm, which tailors content to people’s interests, and drives user engagement, the complaint says.

    TikTok does its own internal studies to find out how the platform is impacting users. The lawsuit cites one group within the company, called “TikTank,” which noted in an internal report that compulsive usage was “rampant” on the platform. It also quotes an unnamed executive who said kids watch TikTok because the algorithm is “really good.”

    “But I think we need to be cognizant of what it might mean for other opportunities. And when I say other opportunities, I literally mean sleep, and eating, and moving around the room, and looking at somebody in the eyes,” the unnamed executive said, according to the complaint.

    TikTok has a 60-minute daily screen time limit for minors, a feature it rolled out in March 2023 with the stated aim of helping teens manage their time on the platform. But Kentucky’s complaint argues that the time limit — which users can easily bypass or disable — was intended more as a public relations tool than anything else.

    The lawsuit says TikTok measured the success of the time limit feature not by whether it reduced the time teens spent on the platform, but by three other metrics — the first of which was “improving public trust in the TikTok platform via media coverage.”

    Reducing screen time among teens was not included as a success metric, the lawsuit said. In fact, it alleged the company had planned to “revisit the design” of the feature if the time-limit feature had caused teens to reduce their TikTok usage by more than 10%.

    TikTok ran an experiment and found the time-limit prompts shaved off just a minute and a half from the average time teens spent on the app — from 108.5 to 107 minutes per day, according to the complaint. But despite the lack of movement, TikTok did not try to make the feature more effective, Kentucky officials say. They allege the ineffectiveness of the feature was, in many ways, by design.

    The complaint says a TikTok executive named Zhu Wenjia gave approval to the feature only if its impact on TikTok’s “core metrics” were minimal.

    TikTok — including its CEO Shou Chew — have talked about the app’s various time management tools, including videos TikTok sends users to encourage them to get off the platform. But a TikTok executive said in an internal meeting those videos are “useful” talking points, but are “not altogether effective.”

    In a section that details the negative impacts TikTok’s facial filters can have on users, Kentucky alleges that TikTok’s algorithm has “prioritized beautiful people” despite knowing internally that content on the platform could “perpetuate a narrow beauty norm.”

    The complaint alleges TikTok changed its algorithm after an internal report noted the app was showing a high “volume of … not attractive subjects” in the app’s main “For You” feed.

    “By changing the TikTok algorithm to show fewer ‘not attractive subjects’ in the For You feed, Defendants took active steps to promote a narrow beauty norm even though it could negatively impact their young users,” the complaint says.

    The lawsuit also takes aim at TikTok’s content-moderation practices.

    It cites internal communication where the company notes its moderation metrics are “largely misleading” because “we are good at moderating the content we capture, but these metrics do not account for the content that we miss.”

    The complaint notes that TikTok knows it has — but does not disclose — significant “leakage” rates, or content that violates the site’s community guidelines but is not removed or moderated. Other social media companies also face similar issues on their platforms.

    For TikTok, the complaint notes the “leakage” rates include roughly 36% of content that normalizes pedophilia and 50% of content that glorifies minor sexual assault.

    The lawsuit also accuses the company of misleading the public about its moderation and allowing some popular creators who were deemed to be “high value” to post content that violates the site’s guidelines.

  • Study Shows a Weekend Warrior Lifestyle Can Lessen Health Risks

    Study Shows a Weekend Warrior Lifestyle Can Lessen Health Risks

    “Weekend Warriors” are often labelled as not being fully committed to a healthier lifestyle, but there are, of course, a myriad reasons as to why people find themselves exercising only a couple of times per week. Bogged down by work stresses or family pressures, or both, many individuals would love to add more training sessions to their weekly planner, but it often remains an incomplete goal due to perceived priorities. Others simply love to get outdoors and enjoy some fresh air when the weekend rolls around but have no interest in sweating it out on a weekday. Then, there’s the weekend warrior that puts in lofty gym, running, or cycling sessions, accruing more actual exercise minutes in less days. No matter the reasons for becoming a weekend warrior, there’s good news because a recently published weekend warrior study says you are on the right track.

    Weekend warriors have a lower risk of developing more than 260 diseases in the future when compared to those who abstain completely, and in many cases the weekend warrior remains just as healthy as those who spread their workouts thinly throughout the week.

    The protective effects of being a weekend warrior, defined by the experts as being someone who performs one or two moderate-to-vigorous physical activity sessions per week, may stave off a wide range of illnesses according to the study recently undertaken by Massachusetts General Hospital, ranging from heart and digestive conditions through to mental and neurological ailments.

     

    How was the Weekend Warrior study carried out?

    With current guidelines recommending at least 150 minutes of moderate-to-physical exercise each week, experts looked at the data of almost 90,000 individuals in the UK Biobank and recorded their exercise patterns and subsequent health outcomes. Do those who exercise for 30 minutes most days become at less risk than those who stack their minutes into fewer sessions? The team looked for links between physical activity and the frequency and duration of sessions to determine a relationship across 16 categories.

    What were the results?

    “Physical activity is known to affect risk of many diseases,” commented co-senior author Shaan Khurshid, MD, MPH, a faculty member in the Demoulas Center for Cardiac Arrhythmias at Massachusetts General Hospital. “Here, we show the potential benefits of weekend warrior activity for risk not only of cardiovascular diseases, as we’ve shown in the past, but also future diseases spanning the whole spectrum, ranging from conditions like chronic kidney disease to mood disorders and beyond.”

    The results showed weekend warrior type activity was associated with a significantly lower risk across 200 diseases compared with inactivity. “Because there appears to be similar benefits for weekend warrior versus regular activity, it may be the total volume of activity, rather than the pattern, that matters most,” said Khurshid. To put that in terms of numbers, weekend warriors and regular exercisers were associated with a 23-28% risk of hypertension and a 43-46% risk of diabetes. These results make for an encouraging

    message because they seem to show that quality rather than quantity is the key to great conditioning. To take things further, the researchers now want to drill down further to find the sweet sport for how long and often the optimum weekly schedule should look. “Future interventions testing the effectiveness of concentrated activity to improve public health are warranted, and patients should be encouraged to engage in guideline-adherent physical activity using any pattern that may work best for them,” said Khurshid.
