Not in our backyard
A year ago, biofuel was a buzzword, a reasonable technical solution to many of our environmental problems. Politicians across the European Union and in North America were busy setting targets, deciding what percentage of transport fuels should be replaced by biofuels by what time.

Stressing this dependence we argue that a distinction ca...
متن کاملNot In Our Backyard : Spectroscopic Support for the CLASH z = 11 Candidate MACS 0647
We report on our first set of spectroscopic Hubble Space Telescope observations of the z ≈ 11 candidate galaxy strongly lensed by the MACSJ0647.7+7015 galaxy cluster. The three lensed images are faint and we show that these early slitless grism observations are of sufficient depth to investigate whether this high-redshift candidate, identified by its strong photometric break at ≈ 1.5μm, could p...
