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."
