We found that agroforests are better overall for bird biodiversity in the tropics than open farms," says study author Cagan H. Sekercioglu (pronounced Cha-awn Shay-care-gee-oh-loo), an assistant professor of biology at the University of Utah.
Chinese physicists unveil a router that uses a quantum control signal to determine the path of a quantum data signal
Dubbed the Phoenix Cluster by the scientists that studied its properties, the incredible stellar mass, officially listed as Cluster SPT-CLJ2344-4243, spews out more than 700 new stars a year and is one of the most intense X-ray producing clusters in
ace a single water droplet on the sole of a gecko toe, and the pad repels the water. The anti-wetting property helps explain how geckos maneuver in rainy tropical conditions
3D printing has been tipped as the next frontier of piracy, but it could also be the next frontier of high-speed nanoscale construction if research at the Vienna University of Technology pans out.
One of the clearest, classic triumphs of technology over tyranny I see is the invention of the man-portable crossbow. With it, an untrained peasant could now reliably and lethally engage a target out to fifty meters – even if that target were a
The threat comes from magnetically-charged plasma thrown out by the sun in coronal mass ejections. Like vast bubbles bursting off the sun's surface, they send millions of tons of gas racing through space that can engulf the Earth with as little as
'Can we find something that has the right features, the ability to live in saltwater, the ability to have a robustness for our process, the ability to withstand the right sorts of thermal tolerances to be productive outside, and the ability to prod
Most people are familiar with crystal skulls from the film Indiana Jones and the Kingdom of the Crystal Skull. However there are actually many serious crystal skull collectors that claim they are pre-Columbian and were made during the Aztec or Maya c
graphene-based magnetic tunnel junction, where a single atom thick layer of carbon atoms in a honeycomb lattice separates two magnetic metal films (cobalt and permalloy). The magnetizations of the films can be aligned parallel or antiparallel, result
By monitoring neural activity, the researchers could essentially see what the monkey was thinking about doing next.
In a second task the jays, colourful members of the crow family and about the same size as jackdaws, realized it was better to use pebbles, which sink, than corks, which float. When Cambridgeshire children, aged four to ten, were set similar tasks,
It happened when a spineless creature on the ocean floor experienced two successive doublings in the amount of its DNA, a major genomic event that eventually led to the evolution of humans and other vertebrates, the researchers said.
Rieger describes the creation of the levitation mechanism for LevLight as the simple part of the project. He modified a Hall Effect Levitator circuit designed by Eirik Taylor to include 300 meters (984 feet) of 20awg wire for the electromagnetic driv
The bloom was dominated by diatoms, a group of algae that require dissolved silicon to make their shells and are known to form large, slimy aggregates with high sinking rates at the end of their blooms. "We were able to prove that over 50 per cent

As a result, a good look at the history of polar bear evolution has had to wait for investigations of the DNA of living animals. Comparing the DNA of different but related species can work as a kind of microscope to look at events as the species sepa
his happened night after night. Then I noticed the sounds of something dropping out of the trees and an animal or being of some kind scraping on the bark a bit as it descended. I tried looking for movement but saw nothing, like an animal or anything.
Aerographite has a density of less than 0.2 milligrams per cubic centimeter, which allows it be compressed by a factor of 1,000, then subsequently spring back to its original state. Despite its extremely low density, it is black and optically-opaque
where the perennial ice cover has been declining at the rate of about 13% per decade and the ice cover as a whole has been declining at the lesser rate of about 5% per decade. In the Antarctic, the trend is opposite to that in the Arctic, with the s
Researchers describe aerographite as “jet black, remains stable, is electrically conductive, ductile and non-transparent.”

They are looking at the concept of moving the space instead of the spacecraft-that is to say, contracting space-time in front of the ship, with a commensurate expansion of the space-time behind it. NASA's Breakthrough Propulsion Physics Project is l
The job of the conscious mind is to form a story out of all our sensations and reflections. Life as we experience it is not just a series of unconnected thoughts and events; it's a coherent narrative unfolding in an orderly universe. But sometimes w
around 950 to 1250 C.E. While this time period is known as being a "dry period," the Pitt researchers have discovered an unexpected complexity to the patterns of drought.

The researchers looked instead for signs of a chemical drilling strategy, testing for the presence of acid-secreting enzymes in different tissues of the worm. One of the enzymes, a proton pump, was abundant in the roots, the part of the worm that pen
"Comparative analyses of 31 fungal genomes (12 generated for this study) suggest that lignin-degrading peroxidases expanded in the lineage leading to the ancestor of the Agaricomycetes, which is reconstructed as a white rot species, and then contrac
To be absolutely sure they've made a true new discovery, rather than simply seen a fluke, physicists wait for enough data so that their statistics reach a level called 5 sigma, meaning that there is only a one in 3.5 million chance the signal isn't
After a quest spanning nearly half a century, physicists on Wednesday said they had found a new sub-atomic particle consistent with the elusive Higgs boson which is believed to confer mass. Rousing cheers and a standing ovation erupted at the Euro
