Space farming is difficult business – plants don’t grow well in zero gravity and harsh radiation damages seeds – but if researchers can get it right, it could provide food, clean water, and oxygen for manned missions far from earth.
It isn’t easy to spot planets far away in our galaxy – normally we can only infer their presence, from the effect they have on their host stars. But now a group of astronomers has demonstrated an easier way to study distant worlds, by detecting the first visible light reflected off an exoplanet.
The Philae probe landing on comet 67P/Churyumov–Gerasimenko on 12 November was awe-inspiring, but the main science phase of Rosetta is yet to come, said Dr Colin Snodgrass, the coordinator of the mission’s ground-based observation campaign and lead scientist on the EU-funded ISANDAL project, speaking from the European Southern Observatory in Chile.
The Large Hadron Collider (LHC), the world’s biggest particle smasher, will look for known unknowns such as dark matter, but also for so-called unknown unknowns that researchers have little idea about. That is according to Professor Fabiola Gianotti, the newly appointed Director-General of CERN, the European Organization for Nuclear Research, which helped identify the Higgs boson.
Robots steer plants to grow in pre-programmed forms.
Insulin resistance links the two diseases.
Railway networks, power stations and telephone grids are constantly being targeted, says Georg Peter.
