It's one of the most serious heart valve problems. Aortic stenosis is a narrowing of the valve that keeps blood flowing in the right direction through the heart. Many patients must choose between having their diseased valve replaced with a mechanical valve or one made from animal tissue. Now, another option is becoming more widely considered, especially for younger patients.

One of the country’s top abortion-rights activists is warning that the Supreme Court’s recent inaction on Texas’ extremely restrictive new abortion law could signal the end of judicial checks and balances on the issue. Former Planned Parenthood President Cecile Richards told The Associated Press this week that the court's decision to let the law take effect may mean assumed court protections on the landmark Roe v. Wade decision are dissolving. Richards released a letter Saturday warning that Texas' Republican leaders "have outlined a roadmap for other Republican governors to follow suit, with the acquiescence of the Supreme Court.” The Texas law prohibits abortions once medical professionals can detect cardiac activity — usually around six weeks.

Just a month ago, President Joe Biden and his health advisers announced big plans to soon deliver a coronavirus vaccine booster shot to all Americans. But while Biden had campaigned for the White House on a pledge to “follow the science,” he now finds himself ahead of it with that lofty pronouncement from Aug. 18. Some of the nation’s top medical advisers have delivered a stinging rebuke of Biden's broad booster idea, in essence telling the White House “not so fast.” On Friday, a key government advisory panel overwhelmingly rejected Biden's plan to give boosters across the board. The experts instead recommended the extra vaccine dose only for those people age 65 or older or those with a high risk of severe disease.

In the past few weeks, South Carolina has set records for COVID-19 hospitalizations and new cases have approached peak levels of last winter. Classes, schools and entire districts have gone virtual, leaving parents frustrated and teachers quitting weeks into the school year. Republicans backed a provision to ban masks in schools in June when cases were low and have not budged. Now teachers, students and parents are struggling with the fallout as more young people contract the delta variant, forcing nearly two dozen schools and two entire districts back to online learning within a month of returning in person.

U.S. envoy John Kerry is on a diplomatic quest to stave off the worst scenarios of global warming, but he's running into resistance from China, the world’s biggest climate polluter. Chinese officials are adamant that the United States must ease confrontation over other matters if it wants China to speed up its climate efforts. Rights advocates and Republican lawmakers say they see signs that China’s pressure may be working. They cite what they say is softening in the administration’s initially strong stand over China’s mass detentions and other abuses of its Muslim Uyghur minority.
