Throughout human history our bodies have adapted over time to the conditions in which we live. Now scientists at the Pennsylvania State University Center for Quantitative Imaging are examining bones to see what they reveal, not only about our ancestors, but about our lifestyles and eating habits.

Human activity has encroached on natural habitats in many places around the world but just outside of Tacoma, Washington, two species are finding ways to live and work together. Soldiers at the Joint Base Lewis-Mcchord are working with conservation biologists to share their training site with a small population of endangered songbirds.

When it comes to understanding the effects of climate change we often think of polar bears and melting ice caps. But there are other places we can look to understand the effects and progress of our changing climate. Invertebrates in our oceans offer a different perspective on what climate change is and how it's progressing.

Claudia Dreifus has interviewed great minds in the fields of astronomy, biology, computer science and more. Her interviews with scientists make up the New York Times column “A conversation with..”

Archaeologists and researchers from a Durham, North Carolina nonprofit have used old maps, traditional archaeology practices and technology to discover new clues about the fate of the lost colony on Roanoke Island in North Carolina.

As our mobile devices become more advance and ubiquitous, marketers are developing more targeted ways of reaching consumers. From GPS tracking to price customization, marketers are using data science to track consumer movement and behavior, raising more concerns about privacy.

At Factur, artists and scientists are able to bring their ideas to life through microprocessors, computer controlled laser cutters, 3D printers and more. We take you inside this collaborative space.

Researchers are testing a new type of implant that has the potential to restore vision to the blind. The implant is a hair like device that generates magnetic fields to induce electrical activity in the brain that stimulates the visual cortex. The device is being developed through a collaboration between Harvard Medical School, Mass General Hospital and the Palo Alto Research Center.

The American Museum of Natural History is working to digitize Charles Darwin’s manuscripts and make them available to the public electronically. David Kohn, Director of the Darwin manuscript project at the American Museum of Natural History joins Hari Sreenivasan.

The perfect sunset lights up the sky with stunning colors and dramatic views. Now you will never miss one thanks to former and current Penn State students who built a model that predicts when and where a perfect sunset will occur.

Vaux’s swifts, a group of migrating birds are known for the dazzling displays they create as they funnel into brick chimneys to roost for the night. But as some brick chimneys are being replaced and demolished these birds are losing their habitat. Our environmental reporting partner EarthFix has the story.

We know about solar energy and wind energy but one company in California, Calwave, is harnessing the renewable power of ocean waves to produce both electricity and freshwater. As part of our ongoing series of reports Peril and Promise: The Challenge of Climate Change, Calwave co-founder Marcus Lehmann joins Hari Sreenivasan via Google Hangout.

Archaeologists are using modern technology to probe a historic city. St. Louis reporter Jim Kirchherr takes us to Cahokia State Historic site in Illinois, where recent excavations have revealed secrets about ancient civilizations.

From smartwatches to Bluetooth shoes, electronic wearable devices have exploded in popularity. Now engineers are working to create lighter, thinner, and more efficient electronics. A team at Carnegie Mellon University has even created a printable smart tattoo that can monitor body functions.

In 2006 millions of bats begin dying of a mysterious disease called white- nose syndrome. For years the disease was confined to the Northeastern United States, but now the deadly disease has spread to bats in the Northwest and the Washington Department of Fish and Wildlife is racing to stop a white-nose outbreak in the bat population there.

Prochlorococcus is a tiny plant like bacteria which is responsible for about 5 percent of all photosynthesis on the planet. Penny Chisholm is an institute professor at the Massachusetts Institute of Technology who was part of the group that discovered the marine microorganism almost 30 years ago and her lab is dedicated to studying the organism today.

Theodore Roosevelt was known to most as the 26th president, he was also an avid naturalist, who traveled the world pursuing the unfamiliar and the unexplored. In The River of Doubt: Theodore Roosevelt's Darkest Journey author Candice Millard describes Roosevelt's trip down an unmapped part of the Amazon River. She joins Hari Sreenivasan via Google Hangout.

While traditional robots are typically made of hard mechanical parts, a new trend in robotics is emerging to create durable and malleable robots using soft materials that conform to the human body. Kari Love, Soft Goods Engineer at robotics company, Super Releaser joins Hari Sreenivasan to talks soft robotics.

While the tech industry continues to grow, there's an increasing need for more skilled workers in fields ranging from mechatronics to information technology. In an effort to bridge this gap an innovative technology program in Michigan known as MAT2 is partnering colleges with employers to create an intensive three year apprenticeship program, equipping students with the technical skills.

For military medicine, the mission to save lives is also a mission to make lives better, and you can see science advancing on this new medical frontier in laboratories and hospitals and at universities all across the country. Next, a look at a unique engineering and research center in Pittsburgh from the PBS documentary Military Medicine: Beyond the Battlefield.
