Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say.
John Wiley and Sons Inc. and the Royal Geographical Society (with IBG) announced today the launch of the Society’s first fully open access journal: Geo: Geography and Environment.

Storm-triggered landslides cause loss of life, property damage, and landscape alterations. For instance, the remnants of Hurricane Camille in 1969 caused 109 deaths in central Virginia, after 600 mm of rain fell in mountainous terrain in 6 hours. More recently, on 8 August 2010, a rainstorm-induced landslide devastated the Chinese county of Zhouqu, causing more than 1000 deaths. A new modeling study by Ren examines the multiple factors, both natural and human caused, that came together to produce this event.
The concentrations of many historically used, and now widely banned, pesticides and other toxic chemicals—called legacy contaminants—can become magnified in an animal that eats contaminated food; however, a new Environmental Toxicology & Chemistry study has found that Arctic mammals metabolize some currently used pesticides, preventing such ‘biomagnification.’
Both shale gas and conventional natural gas have a larger greenhouse gas footprint than do coal or oil, especially for the primary uses of residential and commercial heating.
Researchers have streamlined and simplified a process that uses extracts from seeds of Moringa oleifa trees to purify water, reducing levels of harmful bacteria by 90% to 99%. The hardy trees that are drought resistant are cultivated widely throughout many countries of Africa, Asia, and Latin America.
By tracking hybrids between songbird species, investigators have found that migration routes are under genetic control and could be preventing interbreeding. The research, which is published in Ecology Letters, was conducted using geolocators that, like GPS, record the position of a bird and allow its long distance movement to be tracked.
Researchers who reviewed the impact of El Niño-Southern Oscillation (ENSO) on society have found that there are significant differences in the uptake of forecasts across sectors, with the highest use in agriculture, intermediate use in water resources management, and the lowest in health.
Weight loss at high altitudes—something universally experienced by climbers and people who move to higher terrain—may not be a detrimental effect, but rather is likely an evolutionarily-programmed adaptation, according to a new article in BioEssays.
Using a worm’s contracting and expanding motion, researchers have designed a way for gels to swim in water. The advance, which is described in a Journal of Applied Polymer Science paper, involves the use of a hand-held laser to shrink and swell polymer gels comprised mostly of water.
Journal of Zoology reports on how Taiwan's tiny mientien tree frog is using the cities storm drains to amplify mating calls.
New Phytologist has found that a Chinese species of herb uses its grey leaves to blend into its mountainside surroundings.
Research in Geophysical Research Letters explores permafrost growth at Twelvemile Lake in north central Alaska.
The American Geophysical Union (AGU) today announced that John Orcutt, a distinguished professor of Geophysics at the Scripps Institution of Oceanography and former president of AGU, will serve as the inaugural editor of its newest open access, peer-reviewed journal, Earth and Space Science. The journal will begin accepting papers in late summer 2014, and the first articles will be available in late fall 2014.
New research in the Journal of Biogeography uses citizen science to explore America's flyways
Geophysical Research Letters reports that some types of El Niño could explain recent decade-scale slowdowns in global warming.
Geophysical Research Letters finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea.
new research shows that the islands’ own geological past may have influenced the evolution of the Galapagos Islands' native species.
New research in Biotropica asks FIFA to follow through with its environmental claims. The 2014 FIFA (Fédération Internationale de Football Association) World Cup will be played in Brazil. Its “Football for the Planet” program aims to monitor greenhouse gasses, provide environmentally friendly stadiums, and better waste management. However, FIFA has not maximized this opportunity.
New research in Animal Conservation reveals that a simple bird scaring line can reduce the mortality rate by over 90%.
An Innovative Approach to Understanding Ecological Assessments for Contaminated Sites
Scientists are challenging the theory that icebergs made 1912, the year RMS Titanic was lost to the North Atlantic, an exceptionally hazardous year for shipping.
