| Artificial leaf: Solar-to-fuel roadmap developed for crystalline silicon Posted: 04 Mar 2013 06:15 PM PST A new analysis points the way to optimizing efficiency of an integrated system for harvesting sunlight to make storable fuel.  |
| 'True grit' erodes assumptions about evolution Posted: 04 Mar 2013 06:15 PM PST New work in Argentina where scientists had previously thought Earth's first grasslands emerged 38 million years ago, shows the area at the time covered with tropical forests rich with palms, bamboos and gingers. Grit and volcanic ash in those forests could have caused the evolution of teeth in horse-like animals that scientists mistakenly thought were adaptations in response to emerging grasslands.  |
| Posted: 04 Mar 2013 06:12 PM PST Across their range in central Africa, a staggering 62 percent of all forest elephants have been killed for their ivory over the past decade, new research shows.  |
| Global warming will open unexpected new shipping routes in Arctic, researchers find Posted: 04 Mar 2013 12:18 PM PST Shipping lanes through the Arctic Ocean won't put the Suez and Panama canals out of business anytime soon, but global warming will make these frigid routes much more accessible than ever imagined by melting an unprecedented amount of sea ice during the late summer, new research shows.  |
| One law to rule them all: Sizes within a species appear to follow a universal distribution Posted: 04 Mar 2013 12:16 PM PST Biologists have discovered what might be a universal property of size distributions in living systems. If valid throughout the animal kingdom, it could have profound implications on how we understand population dynamics of large ecosystems.  |
| In Greenland and Antarctic tests, Yeti helps conquer some 'abominable' polar hazards Posted: 04 Mar 2013 09:34 AM PST A century after Western explorers first crossed the dangerous landscapes of the Arctic and Antarctic, researchers have successfully deployed a self-guided robot that uses ground-penetrating radar to map deadly crevasses hidden in ice-covered terrains.  |
| Researchers identify queens, mysterious disease syndrome as key factors in bee colony deaths Posted: 04 Mar 2013 07:56 AM PST A new long-term study of honey bee health has found that a little-understood disease study authors are calling "idiopathic brood disease syndrome," which kills off bee larvae, is the largest risk factor for predicting the death of a bee colony.  |
| Don't be fooled: Flowers mislead traditional taxonomy Posted: 04 Mar 2013 07:55 AM PST For hundreds of years, plant taxonomists have worked to understand how species are related. Until relatively recently, their only reliable source of information about these relationships was the plants' morphology--traits that could be observed, measured, counted, categorized, and described visually. And paramount among these morphological traits were aspects of flower shape and arrangement. However researchers have now found that floral morphologies may be less reliable than other traits in determining the relationships of papilionoid species and genera.  |
