Over the past few months, artificial intelligence has managed to create award-winning art, pass the bar exam and even diagnose illnesses better than some doctors. But as AI grows more sophisticated and popular, the voices warning against the potential dangers are growing louder. Geoff Bennett discussed the concerns with Seth Dorbin of the Responsible AI Institute.

State Department spokesman Ned Price will hold a briefing Tuesday afternoon after drones struck inside Russia's border with Ukraine in the second day of attacks. The briefing is scheduled to begin at 1:45 p.m. ET. Watch the event live in the player above. Ukrainian officials did not formally confirm carrying out drone strikes inside Russia, and they have maintained ambiguity over previous high-profile attacks. But Ukrainian presidential adviser Mikhail Podolyak taunted Moscow in comments on Twitter, and Britain's Defense Ministry said Russia was likely to consider the attacks on Russian bases more than 500 kilometers (300 miles) from the border with Ukraine as "some of the most strategically significant failures of force protection since its invasion of Ukraine."

When you picture a scientist, do you see a white coat-clad PhD-holder pipetting away at a lab bench? Or maybe a skygazer with a different day job who goes out on clear nights for a good view of the stars? Historically speaking, both of those examples fit the bill. German-British astronomer William Herschel was originally an amateur who observed the night sky using homemade telescopes. He discovered Uranus in 1781, working alongside his sister, Caroline Herschel, who made multiple discoveries herself.

The Supreme Court has dealt a major blow to the Biden administration, ending a White House requirement that employees at large businesses get a vaccine or test regularly and wear a mask on the job. The court's conservative majority concluded the administration overstepped its authority by seeking to impose the Occupational Safety and Health Administration's vaccine-or-test rule on U.S. businesses with at least 100 employees. At the same time, the court is allowing the administration to proceed with a vaccine mandate for most health care workers in the U.S., resulting in a mixed decision for the administration. Reacting to the ruling, Psaki hailed the decision allowing mandates for health care workers as "good news," saying the administration will continue to enforce it. On the OSHA ruling, Psaki said the White House will "continue to call on businesses to immediately join those those who have already stepped up, including one third of Fortune 100 companies, to institute vaccination requirements to protect their workers, customers and communities."

Experimental research is aiming to help paralysis victims regain their sense of touch. Miles O’Brien reports on a project run by the Cleveland Functional Electrical Stimulation Center, which is a consortium of the Louis Stokes Cleveland VA Medical Center, MetroHealth Medical Center, Case Western Reserve University, University Hospitals of Cleveland, and the Cleveland Clinic Neurological Institute.

The jury at Kyle Rittenhouse's murder trial Tuesday watched drone video that showed Rittenhouse wheeling around and shooting Joseph Rosenbaum at close range during a night of turbulent protests on the streets of Kenosha. The video, zoomed in and slowed down by a forensic imaging specialist, was played as the prosecution's case appeared to be winding down after a week of testimony in which some of its own witnesses often bolstered Rittenhouse's claim of self-defense. The footage showed Rosenbaum following Rittenhouse before Rittenhouse suddenly spins around and fires his rifle at him. Rosenbaum falls, and Rittenhouse runs around a car. Dr. Doug Kelley, a forensic pathologist with the Milwaukee County medical examiner's office, said Rosenbaum was shot by someone who was within 4 feet of him.

Facebook said it will shut down its face-recognition system and delete the faceprints of more than 1 billion people. "This change will represent one of the largest shifts in facial recognition usage in the technology's history," said a blog post Tuesday from Jerome Pesenti, vice president of artificial intelligence for Facebook's new parent company, Meta. "More than a third of Facebook's daily active users have opted in to our Face Recognition setting and are able to be recognized, and its removal will result in the deletion of more than a billion people's individual facial recognition templates." He said the company was trying to weigh the positive use cases for the technology "against growing societal concerns, especially as regulators have yet to provide clear rules." More than a third of Facebook's daily active users have opted in to have their faces recognized by the social network's system.

Israel's defense minister warned Thursday that his country is prepared to strike Iran, issuing the threat against the Islamic Republic after a fatal drone strike on a oil tanker at sea that his nation blamed on Tehran. The comments by Benny Gantz come as Israel lobbies countries for action at the United Nations over last week's attack on the oil tanker Mercer Street that killed two people. The tanker, struck off Oman in the Arabian Sea, is managed by a firm owned by an Israeli billionaire. The U.S. and the United Kingdom also blamed Iran for the attack, but no country has offered evidence or intelligence to support the claim. Iran, which along with its regional militia allies has launched similar drone attacks, has denied being involved.
