A one-two punch may have helped deck the dinosaurs
A record of volcanism preserved along ancient mid-ocean ridges provides evidence for heightened worldwide magmatic activity 66 million years ago just after the Chicxulub...
Increased UV from ozone depletion sterilizes trees
Paleobotanists put dwarf, bonsai pine trees in growth chambers and subjected them to up to 13 times the UV-B radiation Earth experiences today, simulating...
Got a coastal bridge to retrofit? There’s an optimal approach for that
Life-cycle engineers incorporate -- for the first time -- the three most common failure modes for bridges vulnerable to floods, hurricanes and tsunamis into...
Pheromone from insect that transmits citrus greening (HLB) identified
A new discovery makes it possible to synthesize the substance and use it in traps to attract and kill Asian citrus psyllid, helping control...
Helping authorities respond more quickly to airborne radiological threats

New fuel standards will decrease childhood asthma cases
A new study quantifies health benefits of new a standard for shipping fuel, finding it will result in a 3.6 percent reduction of childhood...
A genetic trigger adds branches to plants, could boost crop yields

Towards a better prediction of solar eruptions
Just one phenomenon may underlie all solar eruptions. Researchers have identified the presence of a confining 'cage' in which a magnetic rope forms, causing...
Removing fossil fuel subsidies will not reduce CO2 emissions as much as hoped
Removing fossil fuel subsidies would have only a small effect on CO2 emissions and renewable energy use, new research has shown. The largest emissions...
Biotechnologists look to bacteria in extremely cold environments for ‘green’ detergents
Despite subzero temperatures, increased UV radiation, little liquid water, and few available nutrients, bacteria living at Earth's poles thrive. They manage it thanks in...
