Light Bulbs That Don't Attract Disease Carrying Insects

Artificial lighting often can act as virtual light magnets attracting a variety of disease carrying insects that can threaten human health. We’ll talk with the leader of a team of researchers who have found that light bulbs can be customized so that they won’t attract these potentially dangerous insects. And… Science World's Bob Doughty tells us that technicians and engineers working on the world's largest and most powerful atom smasher ran into a bit of a snag this past week that could delay its restart after a two year hiatus. Jessica Berman reports on a new study that finds the parasite that causes malaria also produces an odor which attracts mosquitoes, inviting more bites and infections. A new observatory that could help scientists learn more about black holes and supernovas was formally inaugurated and put into full operation recently. Philip Alexiou will have the story. Over 40 years ago, U.S. astronaut Eugene Cernan became the last human being to stand on the surface of the moon. Now the subject of a new documentary, “The last Man on the Moon, Cernan tells Greg Flakus that the U.S. should have a more vigorous space program. Reporting from Nairobi, Hilary Heuler tells us about the recent discovery of a variety of heat-resistant beans, something that could be quite important in the face of climate change. George Putic tells us that a group of European doctors has come up with a new therapy that could soon help millions of former TB patients who continue to have difficulty breathing. We'll have these stories and more on today's edition of VOA's Science, Health and Technology magazine... Science World.

The 'Internet of Things'

Something that’s been creating a lot of buzz within the tech industry is the “Internet of Things”, such as Wi-Fi enabled thermostats as well as washers and dryers. A professor of computer science at Pittsburgh’s Carnegie Mellon University tells us about this computing concept and how its ongoing development could make life easier for us all. Another professor from Carnegie Mellon talks about what many internet historians consider to be the very first internet appliance. A Coca Cola vending machine was turned into a smart machine back in the early 1980’s by thirsty computer science grad students at the university. And… Earlier this week the sun sent a blast of highly charged electrical particles toward Earth. The geomagnetic storm it produced lit up the skies with a spectacular display of what’s called the Aurora Borealis or northern lights. Bob Doughty will tell us all about it. George Putic reports on a new way of detecting flaws in large metal structures such as bridges and airplanes, finding the breaking points before they can cause catastrophic collapse. A Croatian computer whiz has created an application that helps school children with their math homework. Zlatica Hoke tells us that the free "app" has had millions of downloads since it was launched late last year. A Polish bio-tech company has developed a robot that can help physical therapists provide more effective workouts for their patients. Science World’s Doug Bernard has this story by Marveline Dandin. The World Health Organization, in a new report, says non-smoking is becoming the new norm worldwide. But it warns legal battles are slowing efforts to reduce the use of tobacco products. Joe De Capua reports. We'll have these stories and more on today's edition of VOA's Science, Health and Technology magazine... Science World.

Study of Earth's Ionosphere Could Improve GPS Communications

Researchers from NASA’s Jet Propulsion Laboratory along with Canada’s University of New Brunswick are conducting a joint research project to look for and study interference producing irregularities in the Earth's ionosphere that can affect the Global Positioning System. Dr. Richard Langley from the University of New Brunswick, Canada is a member of the research team. He'll tell us about what he and his colleagues hope to learn from this project. Also… Greg Flakus reports on a cyber-security conference that was recently held in Houston, Texas. Attendees discussed what’s being done to counter threats from cyber intrusions. Jessica Berman tells us that researchers are hoping that a drug now used to treat seizures can improve memory in the early stages of Alzheimer's, even reversing the condition. Apple unveiled its new Apple Watch this past Monday. Science World's Doug Bernard tells us about this new wrist-worn device. On Thursday, NASA launched a rocket containing four unmanned spacecraft that were designed to study the magnetic relationship between the Earth and the sun. Science World's Philip Alexiou tells us that the Solar Impulse 2, an airplane that uses only the power of the sun, began its planned trip around the world this week. George Putic tells us about his visit to a Washington DC area company that produces technological products with graphene, which because of its special properties has been called ‘the Material of the 21st Century’. Flying across time zones can throw off your biological clock, sometimes for days. Rosanne Skirble tells us about a new study that allows scientists to follow the mechanics of jet lag in real time. We'll have these stories and more on today's edition of VOA's Science, Health and Technology magazine... Science World.

Small Star Passed Through the Edge of Our Solar System 70,000 Years Ago

An international group of astronomers found that a dim star known as a red dwarf skimmed through the outskirts of our solar system, coming within 8 trillion kilometers of Earth some 70,000 years ago. A member of this group is Dr. Eric Mamajek, from the University of Rochester. He talks about this amazing discovery on today's One on One segment. And… NASA's Dawn spacecraft was captured by the gravitational pull of the dwarf planet Ceres at 1239 UTC Friday, March 6th. George Putic tells us about what NASA is expecting from the mission. Forecasting the weather, it's said, is more an art than a science. Reporting from Colorado Shelly Schelender will tell us about an observation system that is working to improve weather science, through volunteers who share their data through the Internet. Reporting from Manila, Simone Orendain reports that scientists in the Philippines are at work on a strain of rice that could solve one of the world's major health challenges: vitamin A deficiency. Bill Ide, reporting from Beijing tells us that China has pledged to get tough on polluters and tighten enforcement in a bid to clean up its environment, an issue that is one of the Chinese public's biggest concerns. We'll have these stories and more on today's edition of VOA's Science, Health and Technology magazine... Science World.
