Google on Tuesday announced new health initiatives and partnerships at its annual event called “The Check Up.” The Google Health team shared updates about features coming to search, tools for building health apps and the latest in artificial intelligence-powered health research.

During the event, the company discussed new partnerships to help develop AI-assisted ultrasounds, cancer treatment and tuberculosis screenings, but there was a particular buzz around the latest version of its medical large language model called Med-PaLM.

Google first introduced Med-PaLM late last year. It’s designed to provide high-quality responses to medical questions. Med-PaLM was the first AI system to successfully receive a passing score, or more than a 60%, on multiple choice style questions similar to the ones used in U.S. medical licensing exams.

The company said the second iteration of the technology, Med-PaLM 2, consistently performed at an “expert” level on medical exam questions. Med-PaLM 2 has reached more than 85% accuracy, scoring 18% higher than its earlier results.

Dr. Alan Karthikesalingam, a research lead at Google Health, said the company is also testing Med-PaLM’s answers against responses from real doctors and clinicians. He said Med-PaLM’s responses are evaluated for factual accuracy, bias, and potential for harm.

Karthikesalingam showed controlled examples — the demo wasn’t live — of how Med-PaLM 2 might answer questions like “what are the first warning signs of pneumonia?” and “can incontinence be cured?” In some cases, Med-PaLM 2’s answers were on a par, and even more detailed, than the answers that clinicians had provided. But in other cases, Med-PaLM 2’s responses were not as accurate.

“You can see from this sort of work that we’re still learning,” Karthikesalingam said during the event.

Given the sensitive nature of medical information, Karthikesalingam said it could be a while before this technology is at the fingertips of the average consumer. He said it is important to innovate responsibly and in a controlled environment.

Google will continue to work with researchers and experts on Med-PaLM, and Karthikesalingam said the company will share more updates about it in the future.

“The potential here is tremendous,” he said, “but it’s crucial that real-world applications are explored in a responsible and ethical manner.”

The U.K.’s Competition and Markets Authority on Friday said it has narrowed the scope of its investigation into Microsoft’s takeover of games publisher Activision, in a major reprieve for the U.S. tech giant as it pursues an expansion of its video game business.

In February, the CMA published provisional findings from its probe into the takeover, stating at the time that the transaction may result in higher prices, fewer choices and less innovation. Among its concerns, the regulator flagged that the deal would cause a substantial lessening of competition in the console gaming market.

Since then, the regulator has received a “significant amount” of feedback from various industry participants on the deal. With this new evidence, the CMA now says it no longer believes the transaction will hamper competition in console games.

“Having considered the additional evidence provided, we have now provisionally concluded that the merger will not result in a substantial lessening of competition in console gaming services because the cost to Microsoft of withholding Call of Duty from PlayStation would outweigh any gains from taking such action,” Martin Coleman, chair of the independent panel of experts conducting the CMA investigation, said in a statement Friday.

“Our provisional view that this deal raises concerns in the cloud gaming market is not affected by today’s announcement. Our investigation remains on course for completion by the end of April.”

Shares of Activision Blizzard surged more than 6% in U.S. premarket trading. Microsoft shares were slightly lower amid a broad market slump.

The CMA announcement comes after the U.S. technology giant has also won support from some companies that were against the deal, or sitting on the fence.

One of the major concerns from Microsoft’s competitors was that the transaction would block distribution access to Activision’s crown jewel franchise — “Call of Duty.” Last month, Microsoft said it signed a “binding 10-year legal agreement” to bring Call of Duty to Nintendo players on the same day as Microsoft’s Xbox, “with full feature and content parity.”

Additionally, Microsoft signed a deal with Nvidia to bring its Xbox games to Nvidia’s GeForce Now cloud gaming service. Microsoft said it would also bring the Activision games library to Nvidia’s service, if the acquisition closes. Nvidia was reportedly against Microsoft’s Activision takeover.

But Microsoft has yet to bring onside its biggest rival, Sony, which owns the PlayStation console. Microsoft President Brad Smith told CNBC last month that the company is offering Sony the same agreement as it did Nintendo — to make Call of Duty available on PlayStation at the same time as on Xbox, with the same features. Sony still opposes the deal.

“We appreciate the CMA’s rigorous and thorough evaluation of the evidence and welcome its updated provisional findings,” a Microsoft spokesperson told CNBC via email.

“This deal will provide more players with more choice in how they play Call of Duty and their favorite games. We look forward to working with the CMA to resolve any outstanding concerns.”

An Activision spokesperson told CNBC that the CMA’s updated provisional findings “show an improved understanding of the console gaming market and demonstrate a commitment to supporting players and competition.”

“Sony’s campaign to protect its dominance by blocking our merger can’t overcome the facts, and Microsoft has already presented effective and enforceable remedies to address each of the CMA’s remaining concerns. We know this deal will benefit competition, innovation, and consumers in the UK.”

Microsoft still faces uncertainty from regulators in the U.S. and European Union. Smith travelled to Brussels last month to meet with EU regulators.

In the U.S., the Federal Trade Commission filed an antitrust case against Microsoft attempting to block the Activision deal.

Some major companies retain reservations about the acquisition, which includes Google parent Alphabet, according to Bloomberg.

TikTok wants to distance itself from China — but Beijing is getting involved

BEIJING — China says it would “strongly oppose” a forced sale of TikTok, making clear the government’s involvement with the social media giant that’s trying hard to distance itself from Beijing authorities.

The Ministry of Commerce said Thursday that a sale or spinoff of TikTok from its Beijing-based parent ByteDance is subject to Chinese law on tech exports — which requires licenses for the export of certain technology based on national security concerns. ByteDance also owns Douyin, the Chinese version of TikTok that’s popular in the country.

“The Chinese government would make a decision in accordance with law,” said spokesperson Shu Jueting in Chinese, translated by CNBC.

Shu was speaking at the ministry’s weekly press conference, hours ahead of TikTok CEO Shou Zi Chew’s testimony before a U.S. House of Representatives committee.

Lawmakers questioned Chew for more than five hours, and wanted clarity on TikTok’s ability to operate independently of Chinese influences on its parent.

ByteDance did not immediately respond to a request for comment on the Chinese Commerce Ministry’s remarks.

The questioning did not appear to relieve U.S. lawmakers.

“At the end of the day, it was clear from the testimony that Mr. Chew reports to the CEO of ByteDance. ByteDance controls TikTok,” Cameron Kelly, visiting fellow at Brookings Institution, told CNBC’s “Squawk Box Asia” Friday. Kelly used to be a general counsel at the U.S. Department of Commerce from 2009 to 2013.

Kelly said the evidence that ByteDance has legal control of TikTok increases U.S. lawmakers’ doubts over how well the app can demonstrate its independence through restructuring.

TikTok has a “Project Texas” plan to store American user data on U.S. soil — in a bid to show the company’s claims that mainland Chinese authorities have no access to them.

“I don’t think a shutdown a ban or a complete divestiture [of TikTok] is needed. But I do think you have to separate that legal control,” said Kelly, noting that could be done through a trust structure. 

But the commerce ministry’s claim of control over a TikTok sale or spinoff indicates Beijing wants to be involved.

“The Chinese government’s public declaration that it would block the sale of TikTok in the U.S. has little to do with protection of Chinese algorithms and technology and a lot to do with giving Washington a taste of its own medicine,” Daniel Russel, vice president for international security and diplomacy, Asia Society Policy Institute, said in a statement.

“Beijing, having heard [U.S. Commerce] Secretary Raymond’s lament that banning TikTok would infuriate voters under 35, is now double-daring Congress and the Administration to ‘make my day,’” Russel said.

The U.S. has increased restrictions on the ability of American businesses and individuals to work with Chinese businesses on critical tech for high-end semiconductors.

When asked about the commerce ministry’s remarks Thursday, TikTok’s CEO said the app isn’t available in mainland China and is based in Los Angeles. But he said the company did use some of ByteDance’s Chinese employees’ expertise on “engineering projects.”

Chew also told U.S. lawmakers that China-based employees at its parent company ByteDance may still have access to some U.S. data, but that new data will stop flowing once the firm completes its Project Texas plan.

Official Chinese comments have previously emphasized that China-based companies should comply with local laws and regulations when operating overseas.

It’s not immediately clear how China’s export control law, enacted in December 2020, might apply to TikTok.

Different types of exports are managed by different government organizations, “each of which has a separate regulatory system,” the EU Chamber of Commerce in China said in its latest position paper. It called for greater clarity on the roles of the different bodies involved with implementing the export control law.

What’s next for TikTok?

The U.S. and China have increasingly invoked national security as a reason to control tech.

“To be fair, there really are indeed genuine national security risks associated with [TikTok] — and that is one reason why a ban of the app from government phones and military phones makes sense,” said Glenn Gerstell, senior advisor at Center for Strategic and International Studies on CNBC’s “Street Signs Asia” Friday. Gerstell was general counsel of the National Security Agency from 2015 to 2020.

“As to the general public, I don’t see the strategic value in China understanding what the dance moves of a teenager in Minneapolis are. So the general public ban doesn’t make sense to me,” he said.

TikTok has more than 150 million users in the U.S. — or about half of the country’s population.

It’s unclear whether the U.S. will ultimately force ByteDance to sell TikTok or prohibit use of the app in the country. The wildly popular app is already banned from federal government devices.

“We see a 3-6 month period ahead for ByteDance and TikTok to work out a sale to a US tech player with a spin-off less likely and extremely complex to pull off,” Dan Ives, analyst at Wedbush Securities, said in a note.

“If ByteDance fights against this forced sale, TikTok will likely be banned in the US by late 2023.”

Crypto firm Tether says it has around $1.6 billion in excess reserves to back its USDT stablecoin

Cryptocurrency firm Tether estimates it will make $700 million profit in the March quarter, taking its total excess reserves to over $1 billion, the company’s technology chief told CNBC, revealing the latest figures for the first time.

Tether issues the USDT stablecoin, which is pegged one to one with the U.S. dollar. USDT is backed by real-world assets such as fiat currency and U.S. Treasurys so that it is always one to one redeemable with the U.S. dollar.

Stablecoins are used by traders to move in and out of different cryptocurrencies without the need to convert money back into fiat currencies.

Over the years, stablecoin issuers have been criticized for not being transparent enough with the type of assets they hold in their reserve to back their digital currency. Tether held commercial paper, or short-term, unsecured debt that is issued by companies. But Tether didn’t reveal the type of firms or geographical location of companies it had brought the debt from.

Tether eventually sold all of its commercial holdings and moved into U.S. Treasurys, which are considered a more stable and reliable asset. The company produces so-called attestations, which are reports produced by an auditor to attest to the company’s reserves and the assets it holds.

The last report Tether released covering the December quarter showed it had more assets than liabilities.

Tether then revealed in February that it made $700 million in profit in the December quarter. The company’s total assets once liabilities are substracted amount to $960.6 million.

Paolo Ardoino, Tether’s chief technology officer, said the company estimates that the excess reserves will increase by $700 million in the current quarter, which is not yet over. That would take Tether’s excess reserves to $1.66 billion. And it would be the first time Tether crosses the $1 billion mark.

“So this money stays in Tether in the main company in order to further capitalize the stablecoin,” Ardoino said.

Tether makes money from various fees, such as a $1,000 withdrawal fee (with a minimum withdrawal requirement amount of $100,000); from investments in digital tokens and precious metals; and from issuing loans to other institutions.

Circle’s wobbles help Tether

The value of all the USDT in circulation has grown substantially this month from $70.98 billion on March 1 to $78.14 billion on Thursday, according to CoinMarketCap.

That’s thanks in part to the collapse of Silicon Valley Bank this month. Circle, which issues a rival stablecoin called USD Coin, revealed it had $3.3 billion exposure to SVB. USDC lost its dollar peg as investors got concerned about the coin’s stability. Investors flocked to tether. After the U.S. government stepped in to guarantee depositors, USDC regained its peg after it said the $3.3 billion USDC reserve deposit held at SVB will be fully available to people.

Ardoino revealed Tether’s estimated profit for the current quarter while defending the company’s record. When asked if Tether would be able to withstand an event like the SVB crisis, Ardoino asked why people are still questioning its reserves even after traditional lenders collapsed.

“First of all, seriously after Credit Suisse and all the others, all the banks that are failing you are looking again at Tether?” Ardoino said in reference to the instability at Credit Suisse, which eventually led to a regulator-brokered $3.2 billion deal for UBS to buy the Swiss lender.

“Tether is making money and banks are failing. So if you have to put money somewhere, I guess that Tether is the most safe among all the choices,” Ardoino said.
