Unnerved Shanghai residents brave stifling heat for mass COVID tests

Shanghai residents queued up in sweltering heat for compulsory mass testing for COVID-19 on Tuesday, as persistent small outbreaks fuelled anxiety in a city that is still recovering from the painful two-month lockdown lifted a few weeks ago. The nagging daily case tolls in the commercial hub of 25 million and other outbreaks scattered across China have also unnerved global financial markets in recent days, with investors wary of disruptive COVID restrictions.

The White House on Tuesday urged Americans over age 50 to get vaccination boosters against COVID-19 as the fast-spreading Omicron BA.5 subvariant takes hold across the United States and said doing so now would not preclude another shot this fall. U.S. health officials warned that the variant, which makes up a majority of cases in the country, was more resistant than previous variants to immunity, including from prior COVID-19 infection.

WHO says COVID-19 remains a global health emergency

The World Health Organization said on Tuesday that COVID-19 remains a global emergency, nearly 2-1/2 years after it was first declared. The Emergency Committee, made up of independent experts, said in a statement that rising cases, ongoing viral evolution and pressure on health services in a number of countries meant that the situation was still an emergency.

Two pig heart transplants succeed in brain-dead recipients

Surgeons at New York University (NYU) have successfully transplanted genetically-engineered pig hearts into two brain-dead people, researchers said on Tuesday, moving a step closer to a long-term goal of using pig parts to address the shortage of human organs for transplant. The hearts functioned normally, with no signs of rejection during the three-day experiments in June and July, they said at a news conference.

U.S. appeals court revives Roundup weedkiller cancer lawsuit

A federal appeals court on Tuesday revived a lawsuit by a Georgia man claiming Bayer AG's Roundup weedkiller caused his cancer, the latest in a string of legal defeats for the company as it seeks to avoid potentially billions of dollars in damages.

The 11th U.S. Circuit Court of Appeals in Montgomery, Alabama, rejected Bayer's argument that federal law shielded it from state law claims like the one brought by John Carson, who said he was diagnosed with a type of cancer called malignant fibrous histiocytoma in 2016 after using Roundup for 30 years. Carson said the company should have warned of cancer risk on the product's label.

The BA.5 and BA.4 variants together accounted for more than 80% of circulating variants last week, with BA.4 making up 16 %, Walensky told reporters at a White House briefing, adding that the seven-day average of COVID-19 hospital admissions has doubled since early May.
