Scientists have long been trying to develop an effective protection and cure for malaria - one of the deadliest diseases that affects people in tropical areas, especially children. As the World Health Organization announces plans to begin clinical trials of a promising new vaccine, scientists in South Africa report that they too are at an important threshold. George Putic reports, they are testing a compound that could be a single-dose cure for malaria.

Video Genome Initiative Urgently Moves to Freeze DNA Before Species Go Extinct

Earth is in the midst of its sixth mass extinction. The last such event was caused by an asteroid 66 million years ago. It killed off the dinosaurs and practically everything else. So scientists are in a race against time to classify the estimated 11 million species alive today. So far only 2 million are described by science, and researchers are worried many will disappear before they even have a name. VOA’s Rosanne Skirble reports.

Video Robots Slowly Entering Everyday Life

From the entertainment and service industries to manufacturing, medicine, rescue operations and even sports, machines with artificial intelligence — what we usually call robots — are slowly but steadily replacing people. They are cheaper to operate, never get tired and will always keep us company. And for the younger generation, building robots may soon be as popular as building blocks. VOA’s George Putic reports.

Video Garbage Dump Helps Grow a Tomato Farm

Latvia is not among countries whose latitude makes it suitable for growing moderate-climate vegetables, such as tomatoes. But - as we hear from VOA’s George Putic - through clever use of a garbage dump as a source of energy, a large greenhouse near the capital Riga is now growing more than 450 tons of tomatoes annually.

Video Backup Motor May Save Pilots’ Lives

In case of engine failure, multi-engine aircraft often have enough power to land safely, but single-engine planes have a very small chance of avoiding a fatal crash. Now, as we hear from VOA's George Putic, two Spanish inventors say their backup power system, designed specifically for small planes, can significantly improve those odds.

Video Hoverbike Flying Toward Reality

Another long-standing dream of many technological inventors is quickly approaching reality: U.S.- and British-based firms are cooperating in the development of an individual flying platform they call a hoverbike. They say it may revolutionize the concept of flying, including in the U.S. military. VOA’s George Putic reports.

Video Where Does NY Garbage Go?

The population of our planet is growing, as are the piles of garbage that humanity is producing. But where does all this garbage go? It turns out that in New York City, trash is not a total nuisance -- it can also be useful and sometimes even profitable. Victoria Kupchinetsky visited the main recycling facility in New York - to see for herself.

Video Understanding Earth’s Magnetic Field

Most of us hardly ever think about the earth's magnetic field. We might be aware that it helps guide birds as they migrate and ensures that our compasses point north, but not realize that it is one of the crucial components that make life on earth possible. Yet, the processes in the earth’s core that create the magnetic field are poorly understood. VOA’s George Putic reports.

Video Weak Solar Activity Puzzles Scientists

At almost regular intervals, our sun displays phenomena benignly called "sunspots." Actually, they are violent storms. Space scientists closely observe this activity because it may have adverse effects on communications, navigation and even power grids. But the diminishing intensity of the last two solar cycles leaves them puzzled. VOA’s George Putic reports.

Video Melting Sea Ice Spells Death for Polar Bears, Study Says

After two summers on the Arctic ice tracking polar bears, a research team describes survival in a changing habitat where sea ice is melting at a faster pace than predicted. The study in the journal Science paints a grim future for the iconic predator unless global emissions are reduced. VOA’s Rosanne Skirble reports.
