A global antibiotic resistance crisis looms but antibiotics drugs don't make pharma the profits which other medicines do. Roland Pease looks for ways to avert a medical dark age.
Our antibiotics are failing. Bacteria are developing resistance to an increasing number of the drugs that used to kill them. How bleak is the future for global health? Roland Pease looks at scientific issues behind the gathering crisis. The last new class of antibiotics was discovered in the 1980s. Are there any others in the pipeline?

Looking ahead to the European Space Agency's Rosetta mission - the first spacecraft to follow a comet and land a probe on its icy surface. Rosetta arrives at comet Churyumov-Gerasimenko on 6th August. It will then accompany the 4 km chunk of ice and dust close by for more than a year. In November, the craft will a drop a lander to analyse the comet's make-up and photograph the icescape. Andrew Luck-Baker talks about the mission's daring orbital manoeuvres and the big scientific questions the mission is designed to answer.

As we grow older, it is assumed we will all become more forgetful, slower witted and much less useful members of society. Geoff Watts looks at the latest research showing this is not the case. In fact one new theory suggests older people might be slower at psychologists' intelligence tests, merely because they know more.
