Video Glass Buildings Are Deadly for Birds in the City

Millions of birds are killed each year in cities when they strike illuminated buildings, especially ones covered with a lot of glass. Experts say artificial lights at night are confusing for migratory birds. In response, a growing movement to save birds from such crashes has taken place.

Video Robots as Fast as Cheetahs?

Scientists have been experimenting with four-legged robots for years. But providing enough power for those kinds of robots has been a problem. Now, that has changed. Engineers at the Massachusetts Institute of Technology have designed a running robot that operates on batteries.

Video Internet-Connected Refrigerators and Stoves?

New technology was shown at a large consumer electronics show this week, including new robots, devices to help grow hair, and even refrigerators, stoves and potted plants that can connect to the Internet. The Consumer Electronics Show is held yearly in the western U.S. city of Las Vegas.

Audio Science Fiction Becomes Reality for Species Surveys

Many science fiction stories tell about explorers arriving in a new world. The explorers then use some kind of high-tech device to test for breathable air or signs of life. But here on Earth, science fiction is becoming reality through a new sampling technology called environmental DNA, or eDNA.

Video Nations Preparing to Deal with Climate Change

In 2014, the UN released a series of climate reports that showed temperatures on Earth are rising. That is the bad news. The good news is that countries are working together to fight climate change. Experts say a 2-degree rise in temperature above pre-industrial times will cause serious damage.

Video Robot Finds Unexploded Underwater Mines

Many teachers believe that “hands-on” experience is the best way to learn. A group of students in the U.S. is putting that belief to the test. The students are with the Stevens Institute of Technology in Hoboken, New Jersey. They successfully designed and built a robot to find underwater mines.

Audio Study: Regular Exercise Can Change Our DNA

Scientists have long known that diets or exposure to chemicals can change the way genes send and receive chemical signals in the body. But nothing was known about the influence of exercise. Now, Swedish scientists say they have proven that physical exercise changes our DNA.

Audio Expert: High Costs Prevent Automated Airplane Tracking

Airplanes that are very far from land – crossing an ocean, for example – do not always appear on land radio systems and radar. Satellite communication and navigation technology, such as GPS and satellite telephones, allow us to know planes’ locations. But, that technology is not always used.

Video 3-D Printed Model Heart Guides Surgeons, Saves Lives

Researchers are using 3-D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.Pictures from medical tests are sent to a 3-D printer to create a heart in a plaster or clay form.

Video Robots Go To Work For Dentists and Patients

For years, robots have helped doctors perform operations with greater safety, speed and exactness than by using hand-controlled instruments. Now, one such machine reduces the time it takes to make dental crowns. This procedure can repair a damaged tooth in just about two hours.

Audio Is a Fusion Nuclear Reactor Coming Soon?

The United States technological organization Lockheed Martin says it will produce a working fusion nuclear reactor within five years. Lockheed Martin says it may have an operating prototype by 2017, and a version for sale by 2022. Fusion involves forcing together atomic nuclei.
