UK Scientists Find Evidence that High-Energy Solar Particles Trigger Lightning on Earth

According to a new study by scientists at the UK's University of Reading, Empedocles, an ancient Greek philosopher may have been on to something back in the 5th century, BC when he said that lightning was created in the clouds by the rays of the Sun. The British researchers say that they've found evidence that lightning strikes on Earth may be trigged by the high-energy particles generated by the Sun and sent toward our atmosphere by the powerful solar wind. We'll talk with the study's lead author in our One on One Segment. Also… Some hopeful news for those who are afraid to smile because of damaged teeth.  Scientists are now saying that someday a laser may help re-grow human teeth ... giving us all reason to smile. Three new crew members have been rocketed up on another fast-track six hour launch-to-docking mission to the International Space Station We've had several reports in the past about the health dangers of sitting still... and the benefits of exercise or even simply increased motion.  Today we'll hear how sitting less and getting a little more exercise can even help some people who suffer with chronic back, muscle and joint pain. President Obama this week hosted the White House Science Fair, which once again featured extraordinary science projects and experiments from some of America’s most innovative students There are now about 2.1 billion obese people in the world. A new study finds that global obesity rates are climbing. The greatest gain in weight is found in developing countries. These stories and more are coming up for you on VOA's science, health and technology magazine, "Science World."

Ice Melt is Making the Ground Rise in Antarctica

Researchers at Newcastle University in the UK have found yet another way the polar ice melt is affecting the Antarctic landscape.  We'll talk with one the authors of a study that found the ground that was pushed into the Earth's crust by the heavy ice is springing back faster than expected. NASA has Ok’d the construction of a new Mars probe that will study the interior of the red planet and provide some insight into how planets like Earth were created. Anthropologists in Argentina have uncovered bones of what they say may have been the biggest dinosaur that ever lived. Scientists have developed a new experimental malaria vaccine that uses a protein to trap and kill the disease causing parasites. The National Oceanic and Atmospheric Administration released its annual Atlantic Hurricane Season Outlook this past week.  We’ll have a report that examines some of the tools forecasters use to make their predictions. Back in the 1980’s American pop artist Andy Warhol did some experimentation with what was then a brand new computer called the Amiga.  We’ll find out how art and science came together to save Warhol's computer art. These stories and more are coming up for you on VOA's science, health and technology magazine, "Science World."

Astronomers Spot a Coronal Hole in the Sun

Astronomers using NASA's Solar Dynamics Observatory recently found an odd looking square shaped hole in sun.  According to NASA these holes, called coronal holes aren't anything to be worried about.  Today, on our One on One Segment, Dr. Dean Pesnell, the project scientist of NASA's Solar Dynamics Observatory will tell us about coronal holes. And… A Spanish researcher says he has found that we humans aren't ready to meet ET.  The researcher's report indicates that humans are just too stupid and too influenced by religion to be able to handle an encounter with an intelligent extraterrestrial being. While we may not be able to meet ET, the World Health Organization this week gave us some good news and said that we're healthier and living longer than we did in 1990. Swiss scientists have developed a robotic arm that can catch items thrown at it with split-second accuracy. Antarctica seems to have bucked the global warming trend, with portions of it cooling, while the rest of the planet heats up.   U.S. researchers say a common anti-depressant drug appears to slow the growth of brain plaques that are the hallmark of Alzheimer's disease. These stories and more are coming up for you on VOA's science, health and technology magazine, "Science World."

Study Shows that Neaderthals Weren't Inferior to Modern Humans

A pair of researchers said that they've found no real proof that backs up the stereotype of the knuckle dragging, brutish, pre-historic relative of modern man -- the Neanderthal.  Instead there's quite of bit of archeological evidence that suggests that the Neanderthals were more advanced that had been previously thought. And… The periodic table of elements has a new addition this week after researchers discovered a new superheavy element. The W-H-O is declaring a worldwide public health emergency -- warning us that the global threat of polio is back. U.S. scientists have discovered a protein in the blood in young mice can reverse some of the effects of aging in old mice.  That same protein is also present in human blood. While researchers have found that global temperatures are consistently rising, a new study finds there are distinct differences, depending on where you live.

Fabien Cousteau's Underwater 'Mission-31' Set to Begin in June

Fabien Cousteau, grandson of the legendary underwater explorer Jacques Cousteau is getting ready to launch a new mission that will take him and his team under the sea to live and work for 31 days. We'll learn more about the upcoming Mission-31 when Mr. Cousteau joins us on this week's One on One Segment. And… Astronomers this week found an exoplanet that's out in space spinning like a top.  It's the first time the rotation of a planet outside our solar system has been measured. Antibiotics have long been a powerful tool in fighting infections...but now, there over-use could make then a major threat to public health. Coral reefs are being killed at a rapid pace by rising ocean temperatures and increasing acidity. We’ll hear how heat tolerant corals could lead to new ways of conserving these precious reefs. Scientists have come across the coldest brown dwarf star that's been detected so far.   A new non-invasive breath test has been developed that detects lung cancer.   For the first time astronomers have gotten 3 D images of a cosmological entity whose structure, until now has been only theoretical in nature. These stories and more are coming up for you on VOA's science, health and technology magazine, "Science World."

Video Is China's Economic Data Accurate?

Some investors say China's wild stock market gyrations have been made worse by worries about the reliability of that nation's economic data. And some critics say the reports can mislead investors by painting an unrealistically-strong picture of the economy.
