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.
Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality.
While flying high above Earth’s surface, jet fighter pilots may suffer loss of eyesight for brief periods. Some pilots may even lose consciousness. These experiences, commonly called blackouts, can lead to tragic results. An Israeli company may have developed a device that could save pilots’ lives.
For many years, machines have been doing work that people once did, including some difficult jobs. Search and rescue operations employ high technology robots. But there is another area that may soon take jobs traditionally held by human beings: the restaurant industry.
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.
Plankton are a group of different ocean creatures, algae, bacteria and other organisms. A four-year-long study shows that the small organisms are not just food for whales and other sea creatures. It found that plankton are a major provider of oxygen for our planet.
Can the sun provide power for a spaceship to travel to the edge of our solar system? The answer may come from a small satellite. The satellite is designed to test the effectiveness of what is called solar sail propulsion.
Architects, engineers and building supervisors will soon be able to quickly collect information that once took weeks to measure and process.
Scientists have developed a device to gather information about building interiors – the design and exact measurements of a building.
Scientists were shocked to find antibiotic-resistant bacteria on people with no known contact with Western civilization. Find out why this is worrying to scientists and the danger this may bring to fighting disease worldwide. This is an advanced level story with complex medical terms.
The new medical glue can hold tissue together. TissueGlu is the first glue to be approved for use in medical operations. The developers say it is biodegradable meaning it breaks down inside the body.
TB mostly affects poor people and those infected with HIV, the virus that causes AIDS. But the opposite was true 2 ½ centuries ago, when the disease infected wealthy Europeans. Researchers say new findings could change how TB is treated today.
Four tests in 18 months are seen as a sign of the Communist nation’s continuing efforts to make advanced weapons. But China said the tests are, in its words, “purely scientific." Experts worry China could someday lead the United States in developing these super-fast weapons. More
Sri Lanka plans to store and use a billion cubic meters of rainwater each year to support irrigation and power generation. The rainwater would go into the sea if it is not used. Sri Lanka is building the new water management system in the country's dry zone. More
Russia’s newest anti-NGO law, under which the National Endowment for Democracy is declared an “undesirable organization” prohibited from operating in Russia, is the latest evidence that the regime of President Vladimir Putin faces a worsening crisis of political legitimacy. More
Kenya will receive more support to prevent and treat HIV/AIDS. The country will be part of the United States’ DREAMS project aimed at reducing HIV infections among young women. The U.S., the Nike Foundation and the Bill and Melinda Gates Foundation have provided money for the effort. More
The US has promised not to give up its fight against human trafficking. The State Department released its 2015 report on human trafficking this week. It examines the illegal movement of people for forced labor or sex. But some question whether the the report was not harsh enough on some countries. More
May, Might and Must are modal verbs that cause confusion for some learners. The Everyday Grammar team is on the job, explaining how to use these modals to express how certain, or sure, you are of something. You can also use one of them to tell about your wishes for the future. More
This classic American story features a scarecrow that comes to life. Find out what adventures he has as he looks for love and admiration. His only problem is that he has to keep puffing on the pipe the witch gave him. If he stops - something terrible may happen! More
Studies have shown that children from poor families have more difficulty in school than other boys and girls. Children with higher socioeconomic roots seem better prepared and perform better on school tests. Now, American researchers may have found a biological reason for that difference. More
