The "diet" in diet drinks may be a false promise for some soda lovers. True, they deliver the fizz and taste of a soda experience, without the calories. Yet, new research shows they also can leave people with increased food cravings.

On the morning of September 11, 2001, Elizabeth Cascio, an emergency medical technician with the New York City Fire Department, was in Queens directing a first responder training program, when the team got a call to mobilize to the World Trade Center. Her team arrived in a caravan of buses and ambulances just as the second tower collapsed.

With the U.S. in the grips of a frightening surge of coronavirus cases, many parents are understandably eager to know when the COVID-19 vaccine will finally be available for children under 12.

This age group accounts for about 50 million Americans and currently none of them qualify for a shot. But scientists are racing to figure out how one of the COVID-19 vaccines currently available for adults could be given to this age group.

People with compromised immune systems who already got two doses of the Pfizer or Moderna vaccines can now get a third shot to boost their protection from COVID-19.

This week's decision by federal health agencies is welcome news to many patients and their doctors who have been calling for this for months.

The Centers for Disease Control and Prevention revised its guidance on wearing masks Tuesday. In a reversal of its earlier position, the agency is now recommending that some fully vaccinated people wear masks indoors if they live in areas with significant or high spread.

With the highly contagious delta variant surging ferociously, Americans are once again grappling with pandemic anxiety.

The surge has prompted a flurry of new mask mandates, vaccine mandates and other steps to try to get the coronavirus back under control.

Imagine a sound that travels with you no matter where you go. Whether it's a ring, a whoosh or a crickets-like buzz, you can't escape it.

"Mine was like this high-pitched sonic sound," says Elizabeth Fraser, who developed tinnitus last fall. It came on suddenly at a time when many people delayed doctor visits due to the coronavirus pandemic. "It just felt like an invasion in my head, so I was really distressed," Fraser recalls.

A new study estimates that life expectancy in the U.S. decreased by nearly two years between 2018 and 2020, largely due to the COVID-19 pandemic. And the declines were most pronounced among minority groups, including Black and Hispanic people.

In 2018, average life expectancy in the U.S. was about 79 years (78.7). It declined to about 77 years (76.9) by the end of 2020, according to a new study published in the British Medical Journal.

In the early months of the vaccination campaign, Internet access was essential to the search for a vaccination appointment.

But given that more than 14 million people in the U.S. lack reliable access to high speed Internet, technology has been a barrier for some Americans.

The Centers for Disease Control and Prevention says people who are fully vaccinated do not need to wear a mask when they're outdoors unless they're in a crowd, such as attending a live performance, sporting event or parade. People are considered fully vaccinated two weeks after receiving the second dose of the Pfizer or Moderna vaccines, or two weeks after the single dose of the Johnson & Johnson shot.

A political debate has erupted over the idea of requiring proof of COVID-19 vaccination for entry into certain settings. While politicians argue over equity and privacy concerns, some businesses and institutions are moving ahead and developing apps for people to prove their status easily and securely.

When students return to Cornell University for the fall semester, for example, they'll be required to be vaccinated with exemptions for medical or religious reasons.
