It's a deep space mission, more ambitious in scope than anything essayed for almost 40 years. The measure of the risk is that when the Nasa space shuttle takes off next month for its last hurrah a second capsule will sit on the launchpad in case an unprecedented rescue mission is needed.

Adding small amounts of metal to spider silk – a material already stronger and lighter than steel – makes it up to 10 times tougher, German researchers report. The scientists devised a way to incorporate zinc, titanium and aluminium ions into natural spider silk. They say the method could one day prove useful for creating super-strong textiles.

Scientists in the United States have successfully tested the new technique – which involves tiny objects called nanoparticles – on rats and believe it could also be used to help humans.Under the therapy, nanoparticles that release the anti-erectile chemical nitric oxide are rubbed on the problem area, and absorbed directly into the skin.

Scientists have begun to dramatically revise their concept of a baby's mind. By using new research techniques and tools, they've revealed that the baby brain is abuzz with activity, capable of learning astonishing amounts of information in a relatively short time. Unlike the adult mind, babies can take in a much wider spectrum of sensation.

A pen would fall if you dropped it on the Moon, just more slowly." I protested. "No it wouldn't." the TA explained calmly, "because you're too far away from the Earth's gravity."
