Paul Davies and Robert Wagner of Arizona State University have recommended a crowd-sourcing effort to find artificial structures on the moon. After all, lunar missions like NASA's Lunar Reconnaissance Orbiter are returning some stunning, high-resolution imagery of the moon's surface. If aliens have been there, possibly we could spot evidence of their presence. "Although there is only a tiny probability that alien technology would have left traces on the moon in the form of an artifact or surface modification of lunar features, this location has the virtue of being close, and of preserving traces for an immense duration," Davies and Wagner say in their article published in the journal Acta Astronautical .         Indeed, due to the moon's pristine atmosphere, any modification of lunar surface features will remain preserved for eons -- the lack of an atmosphere means features are not eroded away. Unless intelligent aliens came, saw and then covered their...

Hairier skin could also be the key to avoiding being bitten by bed bugs, claim Sheffield academics. Hungry bugs placed on shaved arms were more likely to try to feed compared with those on unshaved arms, the journal Biology Letters reported. Researchers say the hair slows down the bed bugs and warns the victim. Pest controllers say the UK is now experiencing a steep rise in the variety of bed bug infestations. Prof Michael Siva-Jothy, from Sheffield University's Department of Animal and Plant Sciences, recruited 29 brave volunteers to check the theory further, watching the bedbugs as they found a place to feed and removing them only as they were about to bite. He found that more layers of both longer visible hairs and finer, "vellus" hairs close to  the surface appeared to work as a deterrent to the insects, with the finer hairs also acting as an early warning system. Prof Siva-Jothy said: "Our findings show that more body hairs mean better detection of parasites - t...
