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."

Science World - Diet Change 3.5 Million Years Ago May Have Been a Gamechanger in Human Evolution

A recent study from the University Colorado, Boulder suggests a change of diet 3.5 million years ago may have paved the way for ancient hominid species to become more human. The lead author of the study joins us to tell us more.

This past week NASA unveiled its plans to capture, move and someday visit an asteroid, but a draft of a Republican authored NASA budget proposal says not so fast.  The budget draft from the US House Subcommittee on Space calls for scrapping NASA’s asteroid project in favor of more human exploration of space, including manned posts on the Moon and Mars.

And, Rosanne Skirble will tell us about a new ultra-high resolution brain model that's providing scientists with an invaluable tool to better understand brain form and function.

Science World - Meteorites Delivered Key Component to Creation of Life on Earth

Researchers say they now know how reactive phosphorus, an important element that helped start life on Earth, got here.  The team’s leader on the project was University of South Florida’s Matthew Pasek. He joins us to talk about his team’s research and findings.

Other stories we cover include:

After a US sponsored clinical trial in Thailand, scientists have found that a medication used to treat HIV patients can also be effectively used as a preventative.  

Students at the University of Virginia have developed a device that could bring improved water quality for millions in the developing world.

Plus we have another edition of the Science World Quick Quiz!
