All the different colors can fit into a corner of a pixel in your iphone said Jay Guo professor of engineering

whether applying medical grade honey to wound sites in patients undergoing dialysis showed advantages over standard antibiotic use.
or a daily application of medical grade honey to the site of catheter insertion. The study found no significant differences in infection rates
The study also indicated that there may not be a single cause of the collapse of bee colonies in North america the deaths may result from the impact of a complex web of chemicals spanning different types and classes of pesticides and fungicides.
While the researchers were careful not to directly link the complex web of pesticides found in the pollen samples directly to colony collapse disorder the inference is hard to ignore.

#How Google street view Could Fight Invasive Species Google's online street views could help scientists track and fight invasive species over the Internet researchers say.
Mapping where species are in the world is key to monitoring native and invasive organisms.
However collecting this data can be quite an expensive and time-consuming task. To help tackle this problem scientists investigated Google street view through
which Google supplies panoramic views from the streets of hundreds of cities across the world.
Recently Google street view has offered vistas of many places off the beaten track as well such as Antarctica the Galapagos the Amazon Mount everest's base camp
and the Great Barrier reef in Australia. 7 Amazing Places to Visit with Google street view Researchers focused on the pine processionary moth (Thaumetopoea pityocampa)
whose caterpillar is one of the most destructive animals targeting pines and cedars in southern Europe Central asia and North africa devouring the foliage of these trees.
which are highly visible making them potential targets of surveys via Google street view. At the beginning of the work I had the feeling that we were exploring a very unusual way of working at least one
The researchers analyzed data regarding the presence or absence of caterpillar nests collected in these blocks through either direct observation in the field or Google street view.
They found Google street view was 96 percent as accurate as field data. However when the scientists investigated a smaller region only about 185 square miles (484 square km) large divided into blocks 1. 5 square miles (4 square km) in size they found
Google street view matched field data by only 46 percent. The researchers note that smaller regions are more likely to have covered fewer roads by Google street view
and thus less chance to properly spot these caterpillar nests. This effect may be less of a problem in the future as Google street view's coverage expands.
The researchers note that not all species are ideal for survey via Google street view but many could be such as common tree problems
whose symptoms are identifiable from the road including the horse chestnut leaf miner or ash dieback fungus.
The data collected by using Google street view may be useful in monitoring diseases or invasive organism expansion Rossi told Livescience.
In January a different team of scientists found Google street view could also find potential nesting sites in northern Spain for the globally endangered Egyptian vulture.
Altogether these findings suggest Google street view could help scientists monitor both endangered and invasive species. The scientists detailed their findings online Oct 9 in the journal PLOS ONE.

Keystone XL is an export pipeline that will not benefit the United states'energy security and will create far fewer jobs than claimed by the oil industry.
and under President Barack Obama's climate test the pipeline should be rejected. Six years ago I was lucky to get a mention of our canoe expedition through the tar-sands region in the local Canadian papers.
I couldn't have imagined that six years later the U s. president would set a high-profile marker to review the proposed Keystone XL tar-sands pipeline based on its climate impacts.
We cannot allow the Keystone XL pipeline to facilitate the expansion of this highly destructive dirty oil operation.

If people become convinced that a gold-laden city is hiding in the Honduran rain forest it could encourage looting he said damaging the real archaeological sites that no doubt lurk among the tropical vegetation.
'Exploration and preservation In many ways Hoopes said the problem with the Ciudad Blanca media hype echoes crises at archaeological sites around the world:
Keeping sites secret makes life harder for archaeologists however as it's tough to critique your peers'work
With satellite GPS and other technologies just about anyone could easily find a site and Ciudad Blanca may be at particular risk because of legends that it contained massive amounts of gold he said.
As archaeologists increasingly turn to Lidar revealing sites previously gone unnoticed the problem of publicity versus secrecy will only increase he predicted.
Fisher argues that shining a light on previously unnoticed sites is the best way to protect them.
