POPSNew spaceship force field makes Mars trip possible Now this has been confirmed in the laboratory in the UK using apparatus originally built to work on fusion. By recreating in miniature a tiny piece of the Solar Wind, scientists working in the laboratory were able to confirm that a small "hole" in the Solar Wind is all that would be needed to keep the astronauts safe on their journey to our nearest neighbours. Dr. Ruth Bamford, one of the lead researchers at the Rutherford Appleton Laboratory, said, "These initial experiments have shown promise and that it may be possible to shield astronauts from deadly space weather".

POPSNASA launches probe to study edge of solar system "The interstellar boundary regions are critical because they shield us from the vast majority of dangerous galactic cosmic rays, which otherwise would penetrate into Earth's orbit and make human spaceflight much more dangerous," David McComas, IBEX principal investigator from the Southwest Research Institute (SwRI) in San Antonio, Texas, said recently.

POPSThe big bounce vs Big Bang Edwin Hubble and Stephen Hawking, and the discovery of Cosmic background radiation amongst other contributers drafted the Big Bang Theory, but Each knew it was a theory, and destined to be qualified significantly as our our technology and depth of understanding progresses. Big bang is a Theory, not a conclusion. Ask Stephen Hawking to consider any new theories, and evidence, and he would be delighted to consider the evidence. He's a scientist, and a Mathematician, who knows how limited our theories can be with what we know. He is looking for what happened, not what may have happened,.

POPSMysterious New 'Dark Flow' Discovered in Space They discovered that the clusters were moving nearly 2 million mph (3.2 million kph) toward a region in the sky between the constellations of Centaurus and Vela. This motion is different from the outward expansion of the universe (which is accelerated by the force called dark energy).

POPSDoes the Milky Way Influence Earth's Biodiversity Cycles? Research Says "Yes" The boost in cosmic-ray exposure may have a direct effect on Earth's organisms, according to paleontologist Bruce Lieberman. The radiation would lead to higher rates of genetic mutations in organisms or interfere with their ability to repair DNA damage. In this way, the process could lead to new species while killing off others. If future studies confirm the galaxy-biodiversity link, it would force scientists to broaden their ideas about what can influence life on Earth. "Maybe it's not just the climate and the tectonic events on Earth," Lieberman said. "Maybe we have to start thinking more about the extraterrestrial environment as well."

POPSBio-Earth: Are Planets Living Super-Organisms? He believes that expanding the study of life sciences to the core of our world and the depths of outer space will help us find distant relatives of our own Earth -- planets that could also sustain life. To explain why contintental plates drift on the surface of the Earth's molten mantle, Maruyama argues that continents actually have life cycles. Old, cold plates on continental fringes sink to “plate graveyards” deep in the Earth’s mantle, and then rise again, creating volcanoes fueled by three-dimensional convection movements deep below the surface.

POPSBefore the beginning of the universe Alan Guth of MIT, who first proposed the inflation theory nearly three decades ago, says he suspects “the reported lopsidedness will more likely turn out to be a fluke.” However, he adds, “the concept of inflation is really only the framework of a theory, and so far experiment has given us very little guidance in trying to fill in the details.

POPSNew Space Telescope to Explore the Unknown Perhaps most exciting is the possibility that GLAST will find something no one is expecting. This space telescope can peer a range of high-energy gamma rays that is virtually unexplored. "There's such a leap forward in capabilities with GLAST that we have a really good chance of discovering things not even on the list yet," Ritz said. The mission is scheduled for liftoff atop a Delta 2 rocket at 11:45 a.m. EDT on June 7.

POPSWill giant vegetables help solve world food shortage? Scientists have yet to offer a definitive explanation of why space causes the seeds to mutate but they believe that cosmic radiation, micro-gravity and magnetic fields may play a part. Mr Lo said: "After space travel the genetic sequence may change from 1,2,3,4 to 1,2,4,3 or a gene may even disappear so 1,2,3,4 becomes 1, 2, and 4. "We don't think there is any threat to human health because the genes themselves do not mutate, just their sequence changes. "With genetically-modified crops you have seen environmental problems because they have added genes that can damage other organisms. "But with space seeds they don't gain genes, they can only lose them."

POPSThe ABCs of nuclear science - Interesting link * Do you want to know about the modern concept of the nucleus? * How nuclear physicists view the nucleus? * How could anyone measure something that small? * Do you know how we find new elements? * What are accelerators used for? * What is radioactivity and is it dangerous? * What do nuclear physicists really do?

POPSMission To Mars This is strange as conspiracy theorists said that the moon landing could not have taken place due to the radiation and that the astronauts would have been dead before landing on the moon. NASA says here that they will not have prolonged exposure. This brings up the question did the moon landing take place. I mean they only ever had one moon landing.
