Most of us rarely think about the earth's magnetic field. We might know that it helps guide birds as they travel and keeps our compasses pointing north. But, the magnetic field is much more. It is one of the main components that make life on the planet possible.
Entomologists -- scientists who study insects -- are working with other scientists to learn why bee colonies are dying in the United States. They call the problem “colony collapse disorder.” Bees play a role in a third of our food. People are volunteering to help these important insects survive.
Experts say ground-based radar is unable to track about 70% of aircraft flights. This is one reason Malaysia Airways Flight 370 plane has not been found. Now, there are plans to deploy aircraft tracking satellites into space so that no plane will ever be "lost" again.
In the United States, a company is working on a project that could change the way we think about public transportation. Its planned system would move people around in steel tubes. Those passengers would be travelling at speeds of up to 1,200 kilometers per hour.
Earth is in the middle of its sixth mass extinction. Now, scientists are in a race against time to classify the estimated 11 million species alive today. Yet only about two million species are known to science. Researchers are worried many will disappear before they even have a name.
A tiger population count in 2004 found 440 tigers in the Bangladeshi part of the Sundarbans forest, the world’s largest mangrove forest. The new census found that only about 100 tigers are left in the Sundarbans forest of Bangladesh.
Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever-increasing number of cars on the roads. But scientists and students at CATT at the University of Maryland are working to solve that problem.
Scientists who study the sun watch for sunspots -- violent storms that can affect communications, navigation systems and even electric power stations on Earth.
Sunspots are a product of huge electromagnetic storms on the sun. Scientists can observe them eight minutes after they happen.
Researchers, following the animals on the Arctic, discovered sea ice is melting faster than predicted, making it harder for polar bears to survive. They are calling on nations to reduce greenhouse gases. If that does not happen, polar bears could one day disappear from our planet.
Mosquitoes need blood to survive and their favorite target is humans. They are completely driven by smell. How do they find their victims and why do they prefer some people more than others? New research now shows how mosquitoes choose who to bite.
Wind turbines are tall structures with large blades used to produce electricity. They are useful sources of low-cost, renewable energy. But they can also be deadly to birds and bats that fly near the wind turbines. But a new type of wind generator may offer an answer to that problem.
Fish are animals that live in the water. They are also vertebrates – animals that have a backbone and a spine. Have you ever wonder how vertebrates eat food? Now researchers at Brown University have x-ray video that shown the action and why vertebrates use its whole body to eat.
Our Milky Way solar system began as small pieces of star-created gas and dust. Scientists are studying this dust with a student-designed instrument on the American space agency’s New Horizons spacecraft. The agency is busy collecting information from the spacecraft this week in the first-ever flyby.
Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem.

Police and prosecutors sometime recreate crime scenes in an effort to better understand complex cases. Now, scientists in Switzerland are developing virtual reality technologies to recreate crimes scenes. The scientists say these computer-made images can be used for quality recreations of events.
An exhibit at the Aquarium of the Pacific warns the level of the sea around the world could rise by one meter by 2100. Now, scientists are calling for coastal communities to find new way to adapt including new building designs and floating structures.
Shopping centers, stadiums and universities may soon have a new tool to help fight crime. A California company called Knightscope says its robots can predict and prevent crime. Knightscope says the goal is to reduce crime by half in the areas where the robots patrol.
When a dog loses a leg, the animal eventually figures out the best way to get around on three legs. In a short time, the dog learns deal with its physical disability. Now, scientists have developed robots that behave in much the same way. They learn to find a way to deal with the damage.
