Star, Nasa Lens effect reveals distant world  - BBC  The most distant known planet has been detected orbiting a star 17,000 light-years away, say astronomers. The find was made through measurements of the effect the combined mass of the planet and its parent star had on the light of another, more distant star. The newly discovered planet is deep in the constellation of Sagittarius and orbits a dim so-called red-dwarf star. The planet is probably about one-and-a-half times the mass of Jupiter and orbits its star about three times further out than the Earth orbits the Sun.
Jewellery beads, Christopher Henshilwood Cave yields 'earliest jewellery'  - BBC  Left:  The shells were discovered in clusters  The oldest pieces of jewellery made by modern humans have emerged in Africa. Shell beads found in Blombos Cave on the southern tip of the continent are 75,000 years old, scientists say. The pea-sized items all have similar holes which would have allowed them to be strung together into a necklace or bracelet, the researchers believe. "The beads carry a symbolic message. Symbolism is the basis for all that comes afterwards including cave art, personal ornaments and other sophisticated behaviours," Professor Henshilwood, of the University of Bergen, Norway, told BBC News Online.

Marathon effort: What happens to your body when you run a marathon?  - BBC  "Your heart gets stronger, it can on every beat pump considerably more blood," says Mike Stroud. "In your muscles, the fibres are getting bigger and stronger and so can contribute more; and the enzyme systems that allow the oxygen to be combined with fuel can do the job for longer at higher rates. "And combined with all this, the small blood vessels, the capillaries, which go in and around all of these fibres to bring in what's needed and take away the waste, become much richer; so you've got a much better supply, and you can go on for much longer at much higher intensities." "Out of tens of thousand of genes which we looked at, we found 140 which are changed in their expression by exercise - they are either up-regulated or down-regulated. "Some of these changes are related to the growth of new blood vessels; they drive the growth, and some change the local environment making it possible for them to grow."
