The Biden administration is proposing a new framework for the exporting of the advanced computer chips used to develop artificial intelligence, an attempt to balance national security concerns about the technology with the economic interests of producers and other countries.

But the framework proposed Monday also raised concerns of chip industry executives who say the rules would limit access to existing chips used for video games and restrict in 120 countries the chips used for data centers and AI products. Mexico, Portugal, Israel and Switzerland are among the nations that could have limited access.

"Everyone is entitled to his own opinion, but not his own facts," the late New York Sen. Daniel Patrick Moynihan memorably wrote four decades ago.

That seems like a simpler time — especially when you consider Meta's decision to end a fact-checking program on social media apps Facebook, Instagram and Threads and what the ramifications might be for an industry built to bring clarity and to seek truth itself.

Britain plans to criminally charge people who create and share sexually explicit deepfake images to better protect women and girls, a minister said Tuesday.

The U.S. Defense Department has added dozens of Chinese companies, including games and technology company Tencent, artificial intelligence firm SenseTime and the world's biggest battery maker CATL, to a list of companies it says have ties to China's military, prompting some to protest and say they will seek to have the decision reversed.

In recent years, Washington has sought to restrict sharing of advanced technology, including semiconductors and AI, deeming it to be a threat to national security.

The U.S. has updated a decades-old science and technology agreement with China to reflect their growing rivalry for technological dominance. The new agreement, signed Friday after many months of negotiations, has a narrower scope and additional safeguards to minimize the risk to national security.

The State Department said the agreement sustains intellectual property protections, establishes new guardrails to protect the safety and security of researchers and "advances U.S. interests through newly established and strengthened provisions on transparency and data reciprocity."

TikTok has challenged a Canadian government order to shut down the Chinese video-sharing app's business operations in the country that was imposed over national security concerns.

The company said Tuesday that it filed an application for a judicial review with the Federal Court in Vancouver on Dec. 5, which seeks to set aside the order for TikTok to wind-up and cease its business in Canada.

Federal authorities on Tuesday urged telecommunication companies to boost network security following a sprawling Chinese hacking campaign that gave officials in Beijing access to private texts and phone conversations of an unknown number of Americans.

The guidance issued by the FBI and the Cybersecurity and Infrastructure Security Agency is intended to help root out the hackers and prevent similar cyberespionage in the future. Officials who briefed reporters on the recommendations said the U.S. still doesn't know the true scope of China's attack or the extent to which Chinese hackers still have access to U.S. networks.

Instagram is making teen accounts private by default as it tries to make the platform safer for children amid a growing backlash against how social media affects young people's lives.

Beginning Tuesday in the U.S., U.K., Canada and Australia, anyone under 18 who signs up for Instagram will be placed into restrictive teen accounts and those with existing accounts will be migrated over the next 60 days. Teens in the European Union will see their accounts adjusted later this year.

The pager was the first compact mobile communication tool to appear on the mass market and although smartphones have largely pushed it out, some people still use the reliable technology today.

Hours after an apparent attempt on Donald Trump's life over the weekend, Elon Musk took to his social platform X to post a thinking emoji and a comment that "no one is even trying to assassinate" the Democratic president and vice president.

In the midst of anti-Muslim riots in the U.K. — which were ginned up by a false rumor — Musk declared that "civil war is inevitable" in the country.
