Researchers found that in just the past decade, there has been a shift in the most important modifiable risk factors for dementia in the United States. Found out what they are — and more health news — here.

President Joe Biden embarks for Asia on Thursday facing a new risk for the economy at home: a global economic slowdown caused by Russia’s invasion of Ukraine and the pandemic shutting down Chinese cities and factories. The world economy cannot any ballots in this year's elections, but it's a hidden force in the voting that will decide if Democrats retain control of the House and Senate. It’s one more challenge that highlights a steep climb for Biden, whose approval ratings have plunged as prices for everyday goods in the U.S. have soared.

As the comment period begins for the FDA’s proposed ban, public health experts explain the stakes.

A military plane carrying enough specialty infant formula for more than half a million baby bottles arrived Sunday in Indianapolis. It's the first of several flights expected from Europe aimed at relieving a shortage that has sent parents scrambling to find enough to feed their children. President Joe Biden authorized the use of Air Force planes for the effort, dubbed “Operation Fly Formula,” because no commercial flights were available. The nationwide shortage of formula follows the closure of the largest domestic manufacturing plant in Michigan in February due to safety issues.

COVID-19 cases are increasing in the United States – and could get even worse over the coming months, federal health officials warned in urging areas hardest hit to consider reissuing calls for indoor masking. Increasing numbers of COVID-19 infections and hospitalizations are putting more of the country under guidelines issued by the U.S. Centers for Disease Control and Prevention that call for masking and other infection precautions. Right now, about a third of the U.S. population lives in areas that are considered at higher risk — mostly in the Northeast and Midwest. Officials said Wednesday those are areas where people should already be considering wearing masks indoors  — but Americans elsewhere should also take notice.

After mass shootings killed and wounded people grocery shopping, going to church and simply living their lives, the nation marked a milestone of 1 million deaths from COVID-19. The number was once unthinkable. Now it’s a pedestrian reality in the United States, just as is the reality of the continuing epidemic of gun violence that kills tens of thousands of people annually. Americans have always tolerated high rates of death among certain segments of society. But the sheer numbers of what should be preventable deaths, and the apparent acceptance that there’s no policy change coming has people wondering: Is mass death now acceptable in America?

President Joe Biden says cases of monkeypox are “something that everybody should be concerned about.” The president made his first public comments on the disease after being asked about it during his visit to South Korea. He said there's work underway to identify an effective vaccine. And he added that if the disease were to spread "it would be consequential.” The disease is rarely identified outside of Africa, but there have been a number of recent cases in Europe and at least two in the United States. Most people recover from monkeypox without hospitalization, but it can be fatal.

President Joe Biden is off to South Korea and Japan on a six-day trip aimed at building rapport with the Asian nations’ leaders. Biden will try to send a message to China that Russia’s faltering invasion of Ukraine should give Beijing pause about its own saber-rattling in the Pacific. Biden departed Thursday and is set to meet newly elected South Korean President Yoon Suk Yeol and Japanese Prime Minister Fumio Kishida. Their talks will touch on trade, the global supply chain and North Korea’s nuclear program. Biden will also meet with leaders of the alliance known as the Quad, which includes Japan, Australia and India.

Herschel Walker boasts of his charity work helping members of the military who struggle with mental health. The football legend and leading Republican Senate candidate in Georgia says the outreach is done through a program he created, called Patriot Support. But court filings and company documents offer a more complicated picture. They show Walker did not found the program. It's also not a charity. It's an arm of a for-profit hospital chain. Court documents reveal the company has a checkered history treating veterans and reached a $122 million settlement after the Justice Department sued for improperly treating patients. The company denies the allegations. Walker's campaign criticized the media for writing a story about the program.

The U.S. Air Force Academy says three cadets who have refused the COVID-19 vaccine will not be commissioned as military officers but will graduate with bachelor’s degrees. Academy spokesman Dean Miller says a fourth cadet who only recently decided to be vaccinated will graduate and become an Air Force officer. Miller said in a statement Saturday that the three won't be commissioned as long as they remain unvaccinated. He says the Air Force secretary will decide whether the unvaccinated students will be required to pay their educational costs in lieu of service.
