Landing a spacecraft on a celestial body, whether it be the moon, Mars or a comet, is not easy. The European Space Agency found out the hard way in 2003 when its robot Beagle2, which was supposed to send back a signal after landing on Mars, didn’t do so.

But more than a decade after it went missing, the UK Space Agency has announced that the the elusive Beagle2 lander has been re-discovered.

A paper has just been released that will raise health concerns about Bisphenol A again. The paper, “Low-dose exposure to bisphenol A and replacement bisphenol S induces precocious hypothalamic neurogenesis in embryonic zebrafish” was published in the Proceedings of the National Academy of Sciences. This is a very interesting paper, but in terms of implications for human health everything hinges on what “low dose” means.
