Doctors use words like "aggressive" and "highly malignant" to describe the type of brain cancer discovered in Arizona Sen. John McCain.

The cancer is a glioblastoma, the Mayo Clinic said in a statement Wednesday. It was diagnosed after doctors surgically removed a blood clot from above McCain's left eye.

Doctors who were not involved in his care say the procedure likely removed much of the tumor as well.

What do elephant seals and Shakira have in common? They can both keep the beat.

A new study suggests that northern elephant seals memorize the rhythm and pitch of individual vocal calls in order to recognize each other. Knowing who's who is important because elephant seals live in social colonies run by dominant males. Submissive males need to be able to recognize when the alpha male is around in order to avoid getting the blubber kicked out of them.

The United States has ended the ban on large electronics in the cabins of airlines that it announced in March.

A 50-cent meningitis vaccine. Kid-friendly malaria drugs. A vaccine to prevent a deadly diarrheal disease.

These U.S.-funded global health innovations have saved millions of lives around the world. But they also come with an added bonus for Americans.

In a fitness-crazed land of spin classes and CrossFit gyms, Octavia Zahrt found it can be tough to feel as though you're doing enough. "When I was in school in London, I felt really good about my activity. Then I moved to Stanford, and everyone around me seems to be so active and going to the gym every day," she says. "In the San Francisco Bay Area, it's like 75 percent of people walk around here wearing exercise clothes all day, every day, all the time, and just looking really fit."

A former head policy adviser at the Interior Department is accusing the Trump Administration of reassigning him to a lesser position for speaking out about the dangers of climate change.

Joel Clement, a scientist who was director of the Interior Department's Office of Policy Analysis for much of the Obama Administration, was recently reassigned to work to an "accounting office," the agency's Office of Natural Resources and Revenue.

Few inventions in modern history have been as successful as plastic. It's in vehicles and building materials and most of our electronic devices. We wrap stuff in it and even wear it.

Now a research team has tallied up how much plastic has been produced and where much of it has gone. Turns out, it's literally almost everywhere.

California's Obamacare exchange scrubbed its annual rate announcement this week, the latest sign of how the ongoing political drama over the Affordable Care Act is roiling insurance markets nationwide.

Tymia McCullough fidgets in front of a mirror in her hotel room as her mom, Susie Pitts, puts the final touches on her hair and nervously drills her on what she is going to say when she gets to Capitol Hill.

"And this is where you let them know that Medicaid is what?" Pitts asks.

"Health assurance," Tymia responds.

"Health insurance that does what?"

"It pays for the need to see your doctor," Tymia says.

Tymia is just 11 years old. She came to Washington last week to lobby Congress over health care. Her family saw it as a life-or-death fight.

On Aug. 21, a narrow, 70-mile wide swath of the United States from Oregon to South Carolina will be the stage for one of the most (if not the most) spectacular celestial events, a total eclipse of the sun.

Space.com has put together a nice informational guide, including a video and a map explaining where to go, what to expect, and how to watch it safely. This is the first total solar eclipse in America in almost 40 years. The next one in the U.S. will be on April 8, 2024.
