It used to be mostly the military that used small, unpiloted aircraft, called “drones.” The little planes were very costly. But as they have dropped in price more people have begun to use them. Rescue workers and farmers are among the new users. The drones save money and time.
New technology could help to more closely follow passenger airplanes, and find them when they crash; international group to meet next month to discuss changes. Airline industry leaders and regulators want to improve airplane safety. They want better, more dependable tracking devices.
Members of TechShop use high-tech equipment to develop and produce ideas they have for inventions. Members are able to use costly machines including 3D modeling tools and laser cutters. Membership costs for TechShop start at just over $100 per month. | Science in the News
The speed of light is almost 300 million meters per second. At that speed, it would take just one second to travel around the entire world seven-and-a-half times. A biomedical engineer and his team of researchers can now photograph light particles moving at that speed using a unique camera.
Some recently developed mechanical hands can be controlled by thoughts. But people who wear them must use their sight to know what they are touching. So scientists in the United States and South Korea have developed an artificial skin that lets people know more about objects they touch.
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.
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.
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.
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.
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.
Glaucoma is the second leading cause of blindness around the world. In the United States, more than two million people suffer from the disease.
Now, researchers are developing very small needles that may offer a more effective and painless treatment for glaucoma and other eye diseases.
Researchers at Stanford University have developed a new material that can move heat out of buildings and into space. The researchers say the material can cool buildings even on hot days. The cooling material is a very thin sheet with many layers that could be placed on a roof like solar panels.
Can you imagine riding around the streets of your hometown on a skateboard without wheels? In the late 1980s, film director Robert Zemeckis showed a skateboard floating above the ground in his movie Back To The Future Part II. Now, an American company, has moved the idea from a dream to reality.
The disease kills more than 500,000 people every year worldwide. Many of the victims are children. The scientists hope the vaccine will be available by next year. Using the vaccine with existing interventions may save the lives of millions of people in sub-Saharan Africa and worldwide.
Due to rising sea level, farmers are increasingly unable to use fields close to the sea. A farmer in the Netherlands is growing small, but healthy and tasty crops in a mixture of fresh and salt water. Farmers in Pakistan may soon be growing Dutch potatoes in areas affected by rising sea waters.
South Korea is dealing with increasing amounts of waste from electronic devices. These useless or unwanted parts are often called “e-waste.” . The city of Seoul throws out about 10 tons of e-waste each year. Some local governments in South Korea are creating special "e-waste" recycling programs.
About ten cars are stolen every day in Nairobi; 24-year-old technology company owner creates a device that lets owners know where their cars are, and search for their car on a computer or smartphone if it is stolen. They can even send a text message to stop their cars if stolen.
Five years ago, the Mars Rover Spirit got stuck in sand on the red planet. Recently, the other vehicle – Curiosity -- had to go a long way to avoid another sandy area. These incidents led some scientists to develop ways to keep the costly robots from being trapped in the sand.
The gas methane has been linked to rising temperatures on Earth. But methane does not stay in the atmosphere as long as another “greenhouse gas” -- carbon dioxide. Scientists say both gases trap heat from the sun. They prevent heat from escaping into outer space.
Testing new drugs for safety and effectiveness is a costly process in the United States. It also can take a lot of time. Some scientists are now designing silicon computer chips that act like human organs. The scientists think they have found a way to make the process faster and more economical.
Every week, protesters gather in front of the Japanese embassy in Seoul. They want Japan to apologize for forcing thousands of Korean women to have sex with Japanese soldiers during World War II. And they want Japan to make payments to the women for the physical and emotional harm the suffered. More
A strong winter storm struck the Middle East in the middle of January. The storm has been called one of the strongest to hit the area in 10 years. Hundreds of thousands of refugees were affected by the cold and snow.Many of the refugees live in temporary shelters, largely unprotected from the cold. More
Tsunamis are unexpected huge ocean waves. Earthquakes are often the cause of tsunamis. And that can interfere with escape. One coastal town in Washington State is copying a method used in Japan to survive tsunamis. Westport, Washington, is building the first U.S. vertical tsunami shelter. More
Dawn is set to reach the dwarf planet Ceres in March. Scientists will use the spacecraft to gather clues about whether the distant, ice-covered object may have once had conditions to support life as we know it. Dawn, which left Earth seven years ago, will also explore another small planet, Vesta. More
A non-profit group is working to give Kenya’s poorest citizens access to information and technology. The Craft Silicon Foundation provides people who live in Kawangware a computer lab and computer training classes on a mobile bus. The bus has 12 computers powered by the sun through solar panels.

A new study by the Pew Research Center found that the public says women are just as qualified as men to hold top positions in business and politics. But women are still not equally represented in those top jobs. Most Americans think they will see a woman president in their lifetimes. More
The National Football League championship game is hugely popular with sports fans and television advertisers. Tens of millions of people watch the game for the competitive play and for the funny commercials broadcast throughout. Many also enjoy the halftime show. This year Katy Perry will entertain. More
For the past thirty years, artists have been asked to create works of art for New York’s huge subway and train system. The works often relate to city life or to the neighborhood of a station. Some people call it New York’s “underground art museum," with over 250 pieces of original artwork. More
