One in six kids in the United States is obese, a condition that doubles their risk of heart disease. Lorena Ramos, 14, a patient at the Healthy Hearts clinic at Children's Hospital Oakland struggles to lose weight. Will she succeed?

By rushing heart attack victims to the operating table and opening their blocked arteries while their heart attacks are underway, doctors are now able to save 95% of those who make it to the hospital.

This half-hour program looks at heart disease – the number one killer in the United States – from the point of view of a teenager trying to lower her risk, a heart attack survivor, and a scientist working to rebuild damaged hearts.

For decades amateur rocket builders, or "rocketeers," have been trying to reach space. Now with advances in materials and technology, they're able to do it. QUEST travels to rocket launches in fallowed fields and barren deserts to learn more about this addictive hobby and to meet a group of passionate high school rocketeers.

"Insects do not taste like chicken," said Daniella Martin, a charismatic advocate of eating low - make that really low - on the food chain. Through public lectures, cooking demonstrations and her 'Girl Meets Bug' website, Martin preaches the gospel of why, in her opinion, more people should munch on mealworms, crunch a cricket or feast on plump bee larvae.

Photographer Simon Christen shares his passion for observing the environment through the process of time-lapse photography. By training his lens on natural events as fog and the orbiting moon, he discovers things about the natures of these seemingly ubiquitous elements of our world that few have seen before.

Scientists in San Francisco have coaxed mouse hearts to repair themselves from within. The breakthrough could lead to treatments for the 5 million people in the United States living with a damaged heart.

Conservation Biologist Stu Weiss uses specialized photographic equipment to study what makes good Monarch overwintering habitat.

The USGS National Wildlife Health Center investigates animal die-offs and threats to endangered species through on-site investigation and necropsies--animal autopsy--at its headquarters in Madison, Wisconsin.

In 2006, the world learned that honeybees in America and Canada were dying in large numbers, and hives were becoming defunct. Five years later, what have scientists learned about the causes of Colony Collapse Disorder?

Kandis Elliot is on the Botany Department staff at the University of Wisconsin, but she's not a scientist or professor. Elliot is an artist and transforms mere photographs of plants into lush, painterly artworks that educate as well as captivate.

Biomedical researchers are investigating ways to 'grow' new skin in hopes that healing burns can be quicker, safer and more complete.

An exoskeleton suit may seem like science fiction, turning ordinary humans into super heroes, but wearable robots are moving forward into reality.

If you can't abide Brussels sprouts and broccoli, your genes may be to blame. Geneticist Danielle Reed of the Monell Chemical Senses Center in Philadelphia studies differences in our perception of taste and smell. A small blip in DNA might determine if you're bitter blind or have a sweet tooth.

The San Francisco Public Utilities Commission is hard at work on a $4.6 billion, decade-long construction project to overhaul the Hetch Hetchy water system, which delivers water from the Hetch Hetchy reservoir in Yosemite National Park and five local reservoirs to 2.5 million residents in the Bay Area.

For over one hundred and fifty years, scientists have captured images of celestial objects scattered across the night sky. The Pisgah Astronomical Research Institute in North Carolina is attempting to save those historical records before they vanish into a black hole.

Mike Forsberg, a nationally renowned photographer, conservationist, and author from Nebraska, spent four years traveling 100,000 miles across the Great Plains—from North Dakota to Texas—to create a portrait of under-appreciated species and habitats of what many consider "flyover country."

QUEST travels to the Cleveland Museum of Natural History to meet Dr. Spurlock, an anatomist and forensic reconstruction artist who uses clay to re-construct the faces of ancient humans in order to show what they looked like when alive. She also sketches more recently deceased individuals using only their remains in order to help law enforcement solve crimes.

The invasive Asian carp has wreaked havoc in the Mississippi River system. The voracious plankton eaters have out-competed native fish and have become the dominant species in many locations. If the carp reach the Great Lakes, they pose a threat to its $7 billion fishery, so a battle against them is taking place on many fronts.

Within and along the waters of Lake Erie (one of the five Great Lakes), there is a daily struggle for survival between natives and unwelcomed invasive species.

The art and science of salt glaze pottery requires skills and techniques acquired over generations of trial and error. Ben Owen III combines his family’s experiential knowledge of ceramics and additional scientific knowledge to create and improve his unique works of art.

QUEST takes to the high seas with researcher Dirk Rosen to study the underwater world off the California coast. In recent years, the state has established a network of marine protected areas to help fragile habitats and struggling fish populations bounce back. But are they working?

In a dark lab at Lawrence Berkeley National Laboratory, engineers and mathematicians are developing new burners and studying different flames in hopes of better understanding the power of fire and how to make the most efficient flame possible.

In California, more renewable energy comes from geothermal energy than solar and wind, combined. Today, a new technology known as Enhanced Geothermal Systems has the potential to extract even more heat and consequently energy to power steam turbines, but it's not without challenges.

Experts warn that an offshore quake powerful enough to kill thousands and discharge a tsunami could hit the West Coast anytime. QUEST Northwest talks with geologists and seismologists about cutting edge research in earthquake prediction, and what it would look like if the next "Big One" hits close to home.
