Scientific consensus on anthropogenic climate change Posted: 15 May 2013 05:30 PM PDT A comprehensive analysis of peer-reviewed articles on the topic of global warming and climate change has revealed an overwhelming consensus among scientists that recent warming is human-caused.

Insecticides lead to starvation of aquatic organisms Posted: 15 May 2013 05:30 PM PDT Neonicotinoid insecticides have adverse effects not only on bees but also on freshwater invertebrates. Exposure to low but constant concentrations of these substances – which are highly soluble in water – has lethal effects on these aquatic organisms.

World's most extraordinary species mapped for the first time Posted: 15 May 2013 02:44 PM PDT The black-and-white ruffed lemur, Mexican salamander and Sunda pangolin all feature on the first map of the world's most unique and threatened mammals and amphibians.

Malaria infected mosquitoes more attracted to human odor than uninfected mosquitoes Posted: 15 May 2013 02:44 PM PDT Female mosquitoes infected with malaria parasites are significantly more attracted to human odor than uninfected mosquitoes, according to new research. Scientists will now attempt to find out how malaria parasites manipulate their mosquito hosts.

H1N1 discovered in marine mammals Posted: 15 May 2013 02:44 PM PDT Scientists detected the H1N1 (2009) virus in free-ranging northern elephant seals off the central California coast a year after the human pandemic began.

Frog once imported for pregnancy testing brought deadly amphibian disease to US Posted: 15 May 2013 02:43 PM PDT African frogs, originally imported for early 20th century pregnancy tests, carried a deadly amphibian disease to the US, according to new findings. African Clawed Frogs have long been suspected of spreading a harmful fungus called Batrachochytrium dendrobatidis. The earliest known case of the fungus was found in these frogs in their native South Africa. Now scientists have found the first evidence of the disease among introduced feral populations in the US.

Clam fossils divulge secrets of ecologic stability Posted: 15 May 2013 02:40 PM PDT Clam fossils from the middle Devonian era now yield a better paleontological picture of the capacity of ecosystems to remain stable in the face of environmental change, according to new research.

Methane emissions higher than thought across much of U.S. Posted: 15 May 2013 01:50 PM PDT After taking a rented camper outfitted with special equipment to measure methane on a cross-continent drive, a scientist has found that methane emissions across large parts of the US are higher than currently known, confirming what other more local studies have found.

Developmental genetics of space and time Posted: 15 May 2013 01:39 PM PDT Scientists have conducted a study that reveals important and useful insights into how and why developmental genes often take inputs from two independent "morphogen concentration gradients."

Nanoscavengers could usher in next generation water purification Posted: 15 May 2013 12:15 PM PDT A new synthetic nanoparticle could disinfect, depollute, and desalinate contaminated water and then get removed magnetically. This improves upon existing technologies through ultraresponsiveness to magnetism.

Emotional response to climate change influences whether we seek or avoid further information Posted: 15 May 2013 12:14 PM PDT Because information about climate change is ubiquitous in the media, researchers looked at why many Americans know so little about its causes and why many are not interested in finding out more.

Evolution shapes new rules for ant behavior, research finds Posted: 15 May 2013 10:16 AM PDT Biologist Deborah M. Gordon's decades-long study of collective behavior in harvester ant colonies has provided a rare real-time look at natural selection at work.

Oldest evidence of split between Old World monkeys and apes: Primate fossils are 25 million years old Posted: 15 May 2013 10:15 AM PDT Two fossil discoveries from the East African Rift reveal new information about the evolution of primates, according to a new study.

'Fish thermometer' reveals long-standing, global impact of climate change Posted: 15 May 2013 10:15 AM PDT Climate change has been impacting global fisheries for the past four decades by driving species towards cooler, deeper waters, according to scientists.

Billion-year-old water could hold clues to life on Earth and Mars Posted: 15 May 2013 10:15 AM PDT Scientists have discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life. This water could be some of the oldest on the planet and may even contain life. Not just that, but the similarity between the rocks that trapped it and those on Mars raises the hope that comparable life-sustaining water could lie buried beneath the Red Planet's surface.

Fall warming on Antarctic Peninsula driven by tropically forced circulation Posted: 15 May 2013 10:14 AM PDT New research shows that, in recent decades, fall is the only period of extensive warming over the entire Antarctic Peninsula, and it is mostly from atmospheric circulation patterns originating in the tropics.

Squishy hydrogels may be the ticket for studying biological effects of nanoparticles Posted: 15 May 2013 09:51 AM PDT A class of water-loving, jelly-like materials with uses ranges ranging from the mundane, such as superabsorbent diaper liners, to the sophisticated, such as soft contact lenses, could be tapped for a new line of serious work: testing the biological effects of nanoparticles, according to scientists.

Helping forests gain ground on climate change Posted: 15 May 2013 09:50 AM PDT Researchers in Canada have developed guidelines being used by foresters and the timber industry to get a jump on climate change when planting trees.

No idle chatter: Malaria parasites 'talk' to each other Posted: 15 May 2013 09:50 AM PDT Scientists have made the surprise discovery that malaria parasites can 'talk' to each other -- a social behavior to ensure the parasite's survival and improve its chances of being transmitted to other humans. The finding could provide a niche for developing antimalarial drugs and vaccines that prevent or treat the disease by cutting these communication networks.

Groundwater unaffected by shale gas production in Arkansas Posted: 15 May 2013 08:38 AM PDT A new study finds no evidence of groundwater contamination from shale gas production in Arkansas.

Cotton offers a new ecologically friendly way to clean up oil spills Posted: 15 May 2013 08:38 AM PDT With the Deepwater Horizon disaster emphasizing the need for better ways of cleaning up oil spills, scientists are reporting that unprocessed, raw cotton may be an ideal, ecologically friendly answer, with an amazing ability to sop up oil.

Tiny water creepy crawlies from South Korea and the Russian Far East Posted: 15 May 2013 08:38 AM PDT Tiny and hard to notice for the human eye water mites are present almost every stream and in in every continent apart from Antarctica. A new study explores the water mites of the family Torrenticolidae from a variety of habitats in South Korea and the Russian species, providing the description of two new species.

Intestinal bacterium Akkermansia curbs obesity Posted: 15 May 2013 08:37 AM PDT A dominant and useful bacterium called Akkermansia muciniphila is present in the intestinal system of all humans, from babies to the elderly. This microorganism is found in the intestinal mucus layer that protects against intruders. Even more remarkable is that this bacterium has a favorable effect on the disrupted metabolism associated with obesity.

Warming in central China greater than most climate models indicated Posted: 15 May 2013 06:49 AM PDT New data from Central China reveal that temperatures have risen 10 to 14 degrees Fahrenheit over the last 20,000 years in this region, an increase two to four times greater than what many scientists previously thought.

Untangling the tree of life Posted: 15 May 2013 06:48 AM PDT Phylogeneticists examined the reasons why large-scale tree-of-life studies are producing contradictory results and have proposed a suite of novel techniques to resolve the conflicts.

Cells must use their brakes moderately for effective speed control Posted: 15 May 2013 05:53 AM PDT How cells regulate their own function by "accelerating and braking" is important basic knowledge when new intelligent medicines are being developed, or when plant cells are tweaked to produce more bioenergy. Scientists now show a model of how cells' regulatory systems work.

European winter weather harder to forecast in certain years Posted: 15 May 2013 05:52 AM PDT Weather forecasters have a tougher job predicting winter conditions over Europe in some years over others, concludes a new study.
