Vital Signs

In Vital Signs, Sam Baker taps into the expertise of local health care leaders to provide insight into your everyday health and well-being.

Breakthroughs

In Breakthroughs, KERA reporters delve into the latest health-related technologies developed in North Texas and across the state. From the Zika virus to fried chicken, no scientific topic is off limits. 

Learn more in-depth multimedia projects: Surviving Ebola, a look at how Ebola made its way to Dallas and the lessons local hospitals and governments learned; Growing Up After Cancer, the journey of one North Texas boy with cancer; and The Broken Hip, an in-depth look at how a fall can change everything. 

The Trump administration has made a number of changes to health policy in the past two weeks, raising questions about how consumers will be affected. Will the new rules for birth control coverage affect access to an intrauterine device? Might an association health plan help bring down costs for workers at small businesses? And if you're healthy, doesn't a short-term health plan that is cheaper than marketplace coverage make sense? Here are some answers to those questions.

Stephanie Garcia is a high school student. She’s also a 24-year-old inmate at the Lockhart Correctional Facility, a minimum-security women’s prison in Central Texas. Outside, her life was hectic, but here, every day is the same.

In just over four decades, obesity levels in children and teenagers have risen dramatically worldwide, though that rise has been far from uniform.

HIV is no longer considered a death sentence in the United States, and people living with HIV are living longer. That’s largely thanks to antiretroviral drugs, which were first introduced 30 years ago.

As the earliest survivors are growing older, though, doctors are discovering new health challenges related to HIV.

A recent study found 70 percent of Americans binge-watch TV shows, sitting through an average of five episodes per marathon session. But that trend raises some health concerns.

Children's Health System

There are a number of differences between the shelters housing Harvey evacuees and the ones where victims of Katrina went 12 years ago. A big one is telemedicine. Children, especially, are being treated by doctors in remote locations.

High-intensity interval training involves repeated brief bursts of very intense exercise mixed with longer periods of easy recovery. Sounds like something for younger people, but a new study of mice suggests older people might benefit, too.

Worried about Internet companies snooping on your online browsing? You might turn to something called a virtual private network to protect your privacy. But researchers say these networks can themselves be insecure.

Earlier this year, the federal government rolled back rules that would have prevented Internet service providers from tracking your activity online.

Cancer patients face special challenges in addition to the disease — like complications from chemotherapy and weakened immune systems.

Hospitals are recognizing that cancer patients need special emergency care, too.

Surgeons have several options when it comes to rebuilding breasts after surgery related to breast cancer. But for replacing nipples, women have fewer choices.
