Space balloon rides
It is the budget airline of space travel?– cheaper, but it leaves you a long way from your true destination. Paragon Space Development, a firm based in Arizona, has said it will sell balloon rides to an altitude of 30 kilometres for $75,000 a pop. That's 9 km short of Felix Baumgartner's space jump, and far off the 100 km line that marks the edge of space.
Cygnus's trashy success
Orbital Sciences's Cygnus spacecraft has left the International Space Station, completing its first mission and showing that the firm is ready to take on cargo delivery for NASA. As New Scientist went to press, the capsule was drifting down to Earth with 1.3 tonnes of trash and will burn up in Earth's atmosphere.
Cod wars in the Arctic
War is brewing in the Arctic Ocean. Driven north by warming oceans, Atlantic cod have been spotted off the Norwegian island of Spitsbergen, say biologists from the Helmholtz Centre for Polar and Marine Research in Germany. The interlopers may compete with the native Polar cod, which are at a disadvantage because they have a less varied diet.

Carbon dioxide emissions fell 3.8 per cent last year, continuing their downward trend. A mild winter helped, as did the ongoing replacement of coal with cleaner natural gas from fracking.
