Georgia State University Scientists Employ Unique New Approach In Efforts to Develop Ebola Vaccine

Today we’ll feature a couple of stories regarding the deadly Ebola outbreak in West Africa; what's being done to end this scourge and help those already infected with the virus. The medical and science communities are ramping up efforts to develop and produce vaccines and treatments. We'll talk with a scientist who with his colleagues is taking a unique new approach in coming up with a new Ebola vaccine. And… This past Wednesday, a U.S.-based company launched the first commercial observation satellite that will provide us with much higher definition images of Earth than before. We've been hearing about the health benefits that chocolate provides. Today, we'll have a report on the kind of chocolate that will provide most of its advantages, without the health-related problems that sugar-sweetened chocolate can cause. We’ll hear about a new book that discusses the oceans and human’s relationship with them. These stories and more are coming up for you on VOA's science, health and technology magazine, "Science World."

By 2040 the World May Not Have Enough Water to Drink AND Produce Electricity

If you had to pick between having either a good supply of drinking water or electricity what would you choose? A recently published study revealed that we just might have to make that choice by 2040 unless steps are taken to avert a possible crisis that could jeopardize both water AND energy supplies. We talk with two of the study's main authors. And… It may have taken more than a decade of space travel, but this past week, the European Space Agency's Comet Chaser Rosetta made history when it became the first spacecraft to rendezvous with and orbit a comet. The Ebola virus outbreak in West Africa continues its deadly rampage. Medical experts are now saying that perhaps one of the most important keys in stemming the tide of infections may be education. Thousands of people in Toledo, Ohio were recently told not drink the water. The city's water supply from Lake Erie was polluted with a toxin linked to the overgrowth of algae. While the water in Toledo may again be safe to drink, this problem isn't going away any time soon. Scientists are looking at traditional African medicine for possible treatments for Alzheimer's and Parkinson's disease. The Salk Institute for Biological Studies is analyzing the leaves and bark of a tree that grows on an island nation off the coast of West Africa. We’ll have these stories and more on VOA’s Science, Health and Technology news magazine, Science World.

Geologist Finds Evidence That Mars Was Once Warmer and Wetter Than It Is Today

Geologist Gregory Retallack from the University of Oregon, studied images of the Martian landscape as well as mineral and chemical data that were both captured and sent to Earth by the Mars Rover, Curiosity. The images and data revealed that the soil he studied dated back to some 3.7 billion years ago, providing him with evidence that Mars was once, a long time ago, a much warmer and wetter planet than it is today. Professor Retallack joins us today to talk about his research and how Mars, at one time, could have been habitable. Also… The Ebola outbreak in West Africa, so far, has claimed hundreds of lives and infected even many more. Officials at the U.S. Centers for Disease Control and Prevention and other international health agencies are working hard to reduce the spread of the infection. New proposed rules to cut pollution from the 600 coal-fired power plants here in the United States are generating a heated debate.   Those who are for or against the new rules are making sure that the US Environmental Protection Agency knows just how they feel before any new rules are enacted. There is good news and bad news in the fight against malaria. First the bad news: Research indicates drug-resistant malaria is spreading across Southeast Asia.  The good news: a new anti-malarial drug looks promising in an early test. We’ll learn about the “FabLab” at Kenya's University of Nairobi and its role in using 3-D prototyping to spark a manufacturing revolution throughout the country. Officials with the European Space Agency say its Rosetta spacecraft will soon reach the comet it has been chasing for the past ten years.   And we’ll hear what the space agency is hoping to learn from its up-close study and hoped-for landing on the comet. These stories and more are coming up for you on VOA's science, health and technology magazine, "Science World."
