The emptiness of space and the vast distances between locations pose huge and unique challenges to space travel. One of the biggest challenges is the need to either bring everything you'll require with you or to make it along the way. The basic essentials of fuel, water and breathable air are also some of the hardest to guarantee, since every ounce of weight packed onto the spacecraft has to be moved and protected. What if, instead, there was a method of recycling and recombining them?CC0New Era of Space Travel: Private Station May Replace ISS by Late 2020 A possible solution to that problem is what a group of scientists who hail from the California Institute of Technology, the Free University of Berlin and the European Space Agency published in their study in Nature on July 10. There are two methods of doing that, both of which involve electricity. … [Read more...] about Scientists Can Now Recycle Water, Air, Fuel, Making Deep Space Travel Possible

Pro-military news site Forces Network has used the findings as a springboard for the launch of a DVD — 100 Years of the RAF - ostensibly intended to "help the British public learn more about the history of the Royal Air Force" — however, it's doubtful the film will contain any references whatsoever to the many controversial, shadowy and cataclysmic incidents that have frequently blighted the RAF over the course of its century-long existence. Foaming at the Wings In 2008, an inquest ruled 10 RAF servicemen ruled were unlawfully killed when their Hercules aircraft was shot down in Iraq in 2005, with investigators concluding "serious systemic failures" had deprived victims of the "opportunity for survival". The failure of both the Ministry of Defense (MoD) and RAF to fit Hercules planes with explosion-suppressant foam (ESF) constituted a "serious failure" — and … [Read more...] about Weather Weapons, Inside Jobs, Coverups: The Secret History of Britain’s RAF
Star Trek has a lot to answer for. Not content to tease us with unreasonable expectations of phasers and warp drive, it also thrust into the popular imagination the idea of teleportation, in which we step into a giant scanner of some sort and instantaneously find ourselves somewhere else, mind, body and soul intact (and hopefully, unlike Jeff Goldblum, untainted). Theoretically, there are really only two ways this can(’t) be done – physical deconstruction at x and reconstitution at y, or the translation of one’s person into data to be transmitted, then reconverted into matter, like some organic fax machine. Impossible? In 1993 an international group of six scientists, showed that perfect teleportation is possible in principle, or at least not against the laws of physics. More recently scientists both in the US and China have been trying. Just last year, Chinese scientists were able to “teleport” photons to a satellite 300 miles away, using a phenomenon … [Read more...] about Teleportation: will it ever be a possibility?
Early life flourished in a “greenhouse world” in which there were no polar ice sheets and sea temperatures around what is now Britain rose to 25C. The period in Earth’s history known as the “Cambrian explosion” around half a billion years ago saw a massive increase in the diversity of life. This period saw representatives from all major animal groups emerging for the first time throughout the world’s oceans. Read more First birds had beaks with teeth, prehistoric fossils show Notable among these were the chordates – a lineage that would ultimately give rise to vertebrates including humans. Scientists have long suspected this was a particularly warm period in Earth’s history, but until now it has been difficult to prove. “Because scientists cannot directly measure sea temperatures from half a billion years ago, they have to use proxy data – these are measurable quantities that respond in a predictable way to changing … [Read more...] about Global warming drove ‘explosion’ of life 500 million years ago that ultimately gave rise to humans
