Sander's path
Bernie Sanders' six-point loss in Nevada on Saturday night highlighted some of the challenges he'll face heading into the next phase of the Democratic primary. We look at some of the fierce headwinds trying to beat back the "Bern."
Hope for Syria
The regime of Syrian dictator Bashar Assad has accepted the terms of a proposed truce hammered out by Russia and the U.S., but with about a third of Syrian territory in the hands of terrorists, the bloodshed isn't likely to end any time soon.
Powerful backing
Microsoft founder Bill Gates has weighed in with a slightly surprising stance in the dispute between Apple and the Justice Department over whether Apple should comply with a federal magistrate's order to help government investigators hack into an iPhone that belonged to one of the San Bernardino shooters.
Ticking time bomb?
The Indian Point nuclear energy plant lies just 25 miles north of New York City, and critics call it "a disaster waiting to happen." The most recent problem involved a leak of water contaminated with the radioactive byproduct tritium, and there are growing calls for the plant to be shut down permanently.
Beating Zika
A team of CDC investigators is in Brazil examining the possible link between Zika and the birth defect microcephaly. At least 93 travel-related Zika cases are now documented in the U.S., in 22 states and Washington, D.C. We visit lab in Texas spearheading the research to find a vaccine.
Broken hearts
Every year, heart disease kills more than 600,000 people in the U.S. -- one in every four deaths. It's the leading cause of death for both men and women. Many people now live with artificial hearts while they wait for transplants. But as the fakes improve, could heart donations soon become unnecessary?
Race and cancer
Cancer deaths have dropped for all Americans, but racial disparities still exist, especially when it comes to two of the most common killers -- breast and colon cancer -- a new report shows. Three decades after a government report highlighted the problem, why has it been so hard to change?
