||What is Relativity - Einstein's Ideas and Why They Matter - March 15, 2014||This past Friday March 14th was Albert Einstein’s 135th Birthday. The classic equation E=MC squared is part of Albert Einstein's "special theory" of relativity that was published in 1905. Ten years later, in 1915, he published his "general theory" of relativity. Have you ever wondered what these two scientific theories are all about and why after 100 years the science community still considers them to be so incredibly important. A scientist who just wrote a book on Einstein and his theories of relativity joins us today on our One on One Segment to explain. Also… The World Wide Web - the Internet - one of the most valuable and important information resources celebrated its 25th anniversary this past Wednesday (3/12/14). As we celebrate the World Wide Web’s silver anniversary, a new report says that Facebook may soon be a step closer to bringing Internet access to the entire world. This past week, a group of young scientists came to Washington to compete for the top prize of $100,000 in the Intel Science Talent search. We’ll have these stories and much more on this edition of VOA's science, health and technology magazine, "Science World."||14/3/14||Grátis||Ver no iTunes|
||Researchers Find Poor Sleep Quality Helps Cancers Grow Faster and More Agressively - March 08, 2014||This past week scientists in the U.S. brought attention to a pair of promising treatments that could lead to a cure for AIDS. Some lucky students in California recently got a rare opportunity to talk with astronauts in space through a video link. . Researchers in California are working with Mickey Hart who was the drummer for the classic rock band The Grateful Dead to see if exposure to rhythm could help people with neurological diseases lead a better life. And… New research from scientists in Chicago has found evidence that poor sleep quality or having frequent bouts of interrupted sleep can actually speed up and worsen the growth of cancer and diminish our immune system’s ability to control or destroy cancers that are just beginning to develop. Today we talk with the researcher who led the study on our One on One segment. We cover these stories and more on today’s edition of VOA's science, health and technology magazine, "Science World."||7/3/14||Grátis||Ver no iTunes|
||Scientist Develops Revolutionary New System to Name and Classify all of Earth's Life-Forms - March 01, 2014||Today we’ll talk Dr. Boris Vinatzer from Virginia Tech who has developed what some call a revolutionary biological naming and classification system. It’s one that could help scientists better communicate with each other about life on Earth. We’ll learn more about this new system and the benefits it could provide. Also... NASA announced this past week that its Kepler space telescope discovered a record 715 new exoplanets orbiting some 305 stars. For over the last year and a half as many as 25 children in California have been stricken with a mysterious polio-like virus that has caused paralysis in five of the youngsters. These stories and more on this week’s Science World.||28/2/14||Grátis||Ver no iTunes|
||Americans Love Science but Need Help to Better Understand It - February 22, 2014||According to a new survey, Americans, like others in many parts of the world, have a true respect for science and scientists. But, unfortunately, Americans, again like others around the globe, can use some tutoring to better learn and understand science. On today's One on One Segment we talk with the lead author of the section of a new report that examined the public perceptions of science and technology. Also... Today we’ll hear that a bacterium responsible for causing pimples has now been discovered in some grapevines. And, the scientists who made the discovery have named their finding after the late music legend Frank Zappa. Several Ethiopians now living abroad have accused their own government of hacking into their computers and monitoring their private communications. One of the people involved is suing the Ethiopian government over it. There are new concerns about public health in the Indian capital of New Delhi after levels of air pollution there have reached record levels this winter. A new leak of highly radioactive water has been discovered at Japan's tsunami-stricken Fukushima nuclear power plant, but officials there have assured the public that the problem poses no harm the ocean. A new study finds honeybees from colonies that are managed by beekeepers may be infecting their wild bumblebee cousins with disease.||21/2/14||Grátis||Ver no iTunes|
