Judge Blocks Trump Order on Sanctuary City Money

A federal judge blocked President Trump's attempt to withhold funding from "sanctuary cities" that do not cooperate with U.S. immigration officials, saying the president has no authority to attach new conditions to federal spending. U.S. District Judge William Orrick issued the preliminary injunction in two lawsuits — one brought by the city of San Francisco, the other by Santa Clara County — against an executive order targeting communities that protect immigrants from deportation. The injunction will stay in place while the lawsuits work their way through court. The judge rejected the administration's argument that the executive order applies only to a relatively small pot of money and said Trump cannot set new conditions on spending approved by Congress.

U.S. Sets Up Missile Defense in South Korea as North Shows Power

In a defiant bit of timing, South Korea announced key parts of a contentious U.S. missile defense system had been installed a day after rival North Korea showed off its military power. The South's trumpeting of progress on setting up the Terminal High-Altitude Area Defense system, or THAAD, comes as high-powered U.S. military assets converge on the Korean Peninsula and as a combative North Korea signals possible nuclear and missile testing. North Korea conducted live-fire artillery drills on the 85th anniversary of the founding of its million-person strong Korean People's Army. On the same day, a U.S. guided-missile submarine docked in South Korea. And the USS Carl Vinson aircraft carrier is also headed toward the peninsula for a joint exercise with South Korea.

Uber Touts 'Flying Car' Project, Company Announces

Uber is taking to the skies with its next project — "flying cars" — even as all eyes are on its problems on the ground. The embattled ride-hailing company announced plans for an on-demand network of electric aircraft that can take off and land vertically, like a helicopter. It wants to test a network for such vehicles by 2020. The company says its partners in this Elevate initiative include real estate companies, aircraft manufacturers, electric vehicle charger makers and the cities of Dubai, United Arab Emirates, and Dallas-Fort Worth, Texas. Uber's Jeff Holden says urban aviation "is a natural next step for Uber."

FDA Warns of 'Fraudulent' Cancer Cure Companies

The Food and Drug Administration posted warning letters sent to 14 manufacturers, telling them to remove their fraudulent cancer curing products on the internet, NBC News reported. The FDA said most of the products are sold websites and social media sites can be harmful and waste money. The products that are not tested nor approved by the FDA come in all shapes and sizes, from creams to teas. Some contain ingredients that can be risky or interact dangerously with prescription drugs.

Simulating Mom's Womb in Research to Help Earliest Preemies

Researchers are creating an artificial womb to improve care for extremely premature babies — and remarkable animal testing suggests the first-of-its-kind watery incubation so closely mimics mom that it just might work. Today, premature infants weighing as little as a pound are hooked to ventilators and other machines inside incubators. Children's Hospital of Philadelphia is aiming for a gentler solution, to give the tiniest preemies a few more weeks cocooned in a womb-like environment — treating them more like fetuses than newborns in hopes of giving them a better chance of healthy survival. The researchers created a fluid-filled transparent container to simulate how fetuses float in amniotic fluid inside mom's uterus, and attached it to a mechanical placenta that keeps blood oxygenated. In early-stage animal testing, extremely premature lambs appeared to grown normally inside the system for three to four weeks, the team reported. Human testing still is three to five years away, although the team already is in discussions with the Food and Drug Administration. Increasingly hospitals attempt to save the most critically premature infants, those born before 26 weeks gestation and even those right at the limits of viability — 22 to 23 weeks. Extreme prematurity is a leading cause of infant mortality, and those who do survive frequently have serious disabilities such as cerebral palsy.

Derek Jeter, Jeb Bush Group Buying Miami Marlins, Reports Say

A group led by New York Yankees great Derek Jeter and former Florida Gov. Jeb Bush has a deal in place to buy the Miami Marlins for $1.3 billion, according to published reports. Bloomberg reported that a person with knowledge of the deal said the group won the bidding for the team. An MLB source told The Miami Herald that there's an agreement in place but it's pending MLB approval and other details need to be worked out. The team is owned by Jeffrey Loria. The Marlins had no comment. The deal could take months to conclude, but Bush will be the "control person," the Herald reported. Jeter has made no secret of his desire to own a baseball team, telling CNBC in 2016 that it is his "ultimate goal." And Bush comes from a baseball-loving family; his brother George owned the Texas Rangers before becoming president.

Paul McCartney Adds Tour Dates for New York, New Jersey

Paul McCartney is bringing his One On One tour to New Jersey and New York City. Officials announced McCartney will perform for the first time at Prudential Center in Newark on Sept. 11. He'll then perform at Madison Square Garden on Sept. 15, Barclays Center in Brooklyn on Sept. 19 and Nassau Veterans Memorial Coliseum on Long Island on Sept. 26. Promoters say the One On One tour opened in April 2016 in Fresno, California, with McCartney's first performance of "A Hard Day's Night" since the Beatles last played it in 1965. Tickets for the New Jersey and New York shows go on sale to the general public at 10 a.m. May 5.
