Climate sensitivity to CO2 more limited than extreme projections
— 25 Nov 2011 09:00 | EnvironmentA new study suggests that the rate of global warming from doubling of atmospheric carbon dioxide may be less than the most dire estimates of some previous studies - and, in fact, may…
Climate change is making our environment 'bluer'
— 6 Apr 2011 18:49 | EnvironmentThe 'colour' of our environment is becoming 'bluer,' a change that could have important implications for animals' risk of becoming extinct, ecologists have found. In a major study involving…
Protein adaptation shows that life on early earth lived in a hot, acidic environment
— 6 Apr 2011 17:10 | EnvironmentA new study reveals that a group of ancient enzymes adapted to substantial changes in ocean temperature and acidity during the last four billion years, providing evidence that life…
Frozen comet had a watery past, University of Arizona scientists find
— 6 Apr 2011 15:46 | AstronomyFor the first time, scientists have found convincing evidence for the presence of liquid water in a comet, shattering the current paradigm that comets never get warm enough to melt…
Self-cooling observed in graphene electronics
— 4 Apr 2011 17:49 | TechnologyWith the first observation of thermoelectric effects at graphene contacts, University of Illinois researchers found that graphene transistors have a nanoscale cooling effect that reduces…

— 1 Apr 2011 15:45 | TechnologyAs part of the quest to form perfectly smooth single-molecule layers of materials for advanced energy, electronic, and medical devices, researchers at the U.S. Department of Energy's…
Some populations of Fraser River salmon more likely to survive climate change
— 1 Apr 2011 14:42 | EnvironmentPopulations of Fraser River sockeye salmon are so fine-tuned to their environment that any further environmental changes caused by climate change could lead to the disappearance of…
Heavy metals open path to high temperature nanomagnets
— 29 Mar 2011 15:43 | TechnologyHow would you like to store all the films ever made on a device the size of an I-phone? Magnets made of just a few metallic atoms could make it possible to build radically smaller storage…
A very cool pair of brown dwarfs
— 28 Mar 2011 17:42 | AstronomyBrown dwarfs are essentially failed stars: they lack enough mass for gravity to trigger the nuclear reactions that make stars shine. The newly discovered brown dwarf, identified as…
Upgrading the vanadium redox battery
— 18 Mar 2011 15:09 | TechnologyThough considered a promising large-scale energy storage device, the vanadium redox battery's use has been limited by its inability to work well in a wide range of temperatures and…
