It walked on two legs, measured 2-3m in length with a large tail and weighed between…
Fluctuating Weather Makes Birds More Flexible Singers
Mixing it up helps birds ensure that their songs are heard no matter what the habitat, say researchers at Australian National University and the National Evolutionary Synthesis Center.

Uncovering the World’s Unseen Science
Global comparisons of scientific output are commonplace. As non-experts, policymakers and administrators must rely on indexes of impact and recognition — counts of published papers and citations, and the prestige of source journals — to assess the impact of public spending and to allocate research funds. The gold standard is the Scientific Citation Index Expanded,…
Bacteria Tweaked to Make Fuel From Sunlight
As part of the bid to find viable alternatives to fossil fuels, chemists have artificially engineered bacteria capable of growing some of the raw materials necessary for fuel and plastic production using sunlight. The cyanobacteria are naturally capable of photosynthesis, meaning they have an inherent ability to fix carbon from carbon dioxide into useful hydrocarbons….
