On Tuesday, chip designer Nvidia announced in an SEC filing that new US export restrictions on its high-end AI GPU chips to China are now in effect sooner than expected, according to a report from Reuters. The curbs were initially scheduled to take effect 30 days after their announcement on October 17 and are designed to prevent China, Iran, and Russia from acquiring advanced AI chips.

The banned chips are advanced graphics processing units (GPUs) that are commonly used for training and running deep learning AI applications similar to ChatGPT and AI image generators, among other uses. GPUs are well-suited for neural networks because their massively parallel architecture performs the necessary matrix multiplications involved in running neural networks faster than conventional processors.

The Biden administration initially announced an advanced AI chip export ban in September 2022, and in reaction, Nvidia designed and released new chips, the A800 and H800, to comply with those export rules for the Chinese market. In November 2022, Nvidia told The Verge that the A800 “meets the US Government’s clear test for reduced export control and cannot be programmed to exceed it.” However, the new curbs enacted Monday specifically halt the exports of these modified Nvidia AI chips. The Nvidia A100, H100, and L40S chips are also included in the export restrictions.

The move by CVS comes after an advisory panel for the Food and Drug Administration last month voted unanimously that the common decongestant, phenylephrine, is ineffective at treating a stuffy nose. But it comes ahead of the FDA itself acting on the vote, which will likely lead the agency to revoke phenylephrine’s approval, eventually.

In a statement to Ars, a CVS spokesperson suggested the FDA advisory panel’s vote was the impetus for the change, but that it would “follow direction from the FDA.”

State attorneys general in 41 states and the District of Columbia sued Meta today. The move comes after the conclusion of a multistate probe launched in 2021, where a bipartisan coalition of state enforcers began examining how Facebook and Instagram features are designed to allegedly addict and harm kids.

Back in 2021, the Massachusetts attorney general’s office led the multistate probe investigating “Instagram’s impacts on young people” after Facebook whistleblower Frances Haugen revealed that Facebook knew Instagram was “toxic” to teen girls but downplayed risks to the public. In a press release today, Massachusetts Attorney General Andrea Joy Campbell accused Meta of “deliberately” exploiting “young users’ vulnerabilities for profit.”

Eight states and Washington, DC, filed lawsuits against Meta in state and local courts, while 33 states filed a joint lawsuit in a federal court in California, The Washington Post reported.
