Humans have experienced global catastrophes in the past, says Nick Bostrom, director of Oxford s Future of Humanity Institute. But modern technology has brought new potential risks.

Science and music: What is it about music that moves us? Why does it seem to be universal in humans? And what can science tell us about the hows and whys of our musical minds? Find out in this extended interview with music psychologist John Sloboda and Nature's Phil Ball.

03 July: A journey to the edge of the solar system with Voyager 2, a simpler recipe for stem cells, musical minds, an increase in extinction risk predicted by a new model, and the reincarnation of Schroedinger's cat.

Astronomer Eric Jensen and microbiologist Amy Vollmer give an introduction to an interdisciplinary subject: astrobiology, the study of life beyond Earth. By trying to understand how Earth formed and evolved, and how microbial life forms have evolved and adapted to living in extreme environments on this planet, scientists are developing a better understanding of the possibilities for life elsewhere in the universe. Topics that Jensen and Vollmer explore include the early history of Earth, the formation of critical organic molecules, data from Mars, the likelihood of stars like our Sun and planets like Earth existing in the galaxy, and extreme environments on Earth that may give us clues about the limits of life elsewhere.

Kevin J. Anderson, the best selling science fiction and fantasy author, is our guest today. (His website.) Co-author of the Dune prequels, his original works include the Saga of Seven Suns series and the Nebula Award-nominated Assemblers of Infinity. A prolific science fiction author, he has had at least 32 of his novels on the various best seller lists including the famous New York Times Bestseller's list. His books have been translated into at least twenty-four languages, and have sold over 16 million copies worldwide. He has written spin-off novels for Star Wars, StarCraft, Titan A.E., and The X-Files. In addition to all this, he has served as a judge in the Writers of the Future contest. Hosted by Stephen Euin Cobb, this is the July 2, 2008 episode of The Future And You. [Running time: 56 minutes] In today's interview Kevin J. Anderson describes his ideas and observations on a variety of topics such as the current global energy crisis, peak oil theory, solar and nuclear power, and his new purchase of a fuel efficient car. Having returned from a month long promotional tour of Australia and New Zealand, he describes his surprise at how different public opinion about Global Warming is down there compared to in the US. There is an overwhelming acceptance of the concept, and crowds greet Al Gore with the admiration and enthusiasm usually reserved for rock stars. He is not comfortable that we will soon retire the space shuttle with nothing to replace it. Even now, he points out, we have to ask the Russians to take our astronauts up to the international space station for us. He also ponders some serious questions: If the Middle Eastern dictators thumb their noses at China, the Chinese government--which unlike the USA does not set limits on how it treats its own people much less outsiders--may very well invade the oil rich countries and take their oil by force. And if future nanotechnology allows everyone to have everything they want what kind of civilization will we have? Will people still work? Will most crime go away? What in our lives will remain the same?

The darkness is coming. With 95% of the content of the universe being dark, we ask Jochen Weller about dark energy and models that describe the expansion of the universe [16:28 - 31:17]. As usual we also get the latest news from Megan [02:09 - 10:28] and find out what you can see in the night sky from Ian [33:24 - 43:36].

This week on Skepticality, Derek and Swoopy return from the desert with highlights from "The Amazing Meeting 6" conference in Las Vegas (hosted by the James Randi Educational Foundation). Joining them are two skeptics who are changing the face of popular science: astrophysicist Dr. Neil deGrasse Tyson, and MythBuster Adam Savage. Â The incomparable Neil deGrasse Tyson (Director of the Hayden Planetarium at the American Museum of Natural History, current host of Nova Science Now, and the only astrophysicist to be named one of PeopleÂmagazine's "Sexiest Men Alive") talks with Swoopy about getting the United States back on track as science innovators. (He also sets the record straight about Pluto.) and in his third appearance on Skepticality, Adam discusses his evolution from artist and model maker to skeptic and television scientistâas well as thoughts about his life after MythBusters.Â

For those of you who are familiar with Romans 1:22, you know how that phrase ends. And we have no greater example than this from NASA's website. One of their officials wants to put CEOs on trial for lies against the pseudoscience of global warming. They're also rewriting already established science and demaning that everyone on the planet who has eyes to ignore what they've seen and what they know to be true and just trust in the transcendent wisdom of the all seeing and all knowing NASA scientist.

About a hundred and forty years ago, the light from a supernova explosion in our galaxy reached the Earth, but no one saw it. The discovery of this supernova remnant helps astronomers better understand how often these stellar time-bombs go off in our galaxy.

July 1, 2008. The elusive planet Mercury is in the east before dawn now. Throughout July, no matter where you are on Earth, you have a good opportunity to find Mercury in the predawn sky.

REPEAT Is the public interested in science? The signs aren't encouraging. The Hubble Telescope teeters on the edge of breakdown, and the public's response is lukewarm. Science coverage in the media continues to shrink like cheap cotton... and science superstars on TV or in the movies are as rare as lanthanum. As we consider why today's folk give science the big yawn, we'll talk to people whose job it is to bring lab findings to the public. Also, a new study traces to childhood our psychological aversion to science. Plus, Seth re-lives his childhood at the San Francisco Exploratorium. BONUS: sing along with Seth!

After astronauts make the first tentative steps onto the surface of Mars, a big goal will be colonization of the Red Planet. The first trailblazers who try to live on Mars will have their work cut out for them, being in an environment totally hostile to life. What challenges will they face, and how might they overcome them?

Aaron Price won a Chambliss Astronomy Achievement Student Award for this poster on the cataclysmic variable star BZ UMa. Aaron walks us through his poster and results.

Earth’s growing population means more vehicles, and more pollution. A Shell scientist describes a gas-to-liquids process for a cleaner-burning fuel.

In this film,you will see how modern astronomy and physics imply a fact that materialists are unwilling to accept, that is, the existence of a Creator.

The robot sub being tested now in Antarctica might someday be used to find signs of life on other worlds. For example, Jupiter’s moon Europa might harbor life swimming in an ocean covered by ice.

The Amphibian Ark is a global effort to collect amphibians in zoos, aquariums, and elsewhere. EarthSky asks: why amphibians?

This summer, NASA engineers will try to realize a dream older than the Space Age itself: the deployment of a working solar sail in Earth orbit. The name of the device is NanoSail-D and it is scheduled for launch onboard a SpaceX Falcon 1 rocket as early as July 29, 2008. Please vote for this podcast at PodcastAlley! Get this podcast story.

In this episode, we'll look at a couple of bogus attempts to undermine science related to Lunar and Solar astrophysics. I apologise for the somewhat erratic sound/volume in this video. I did not record it all in one go, and I have no idea what I'm doing in iMovie. The next one will be better. To those who were referred to me by DonExodus2, thank you for checking out my videos and I hope you'll like what you see enough to subscribe. To DonExodus2 himself, thank you very much indeed for your support. Various multimedia in this video was created by NASA/ESA/JAXA/ESO/Berkley/Exeter
