COLLEGE PARK, Md -- A University of Maryland-led team has compiled the first decades-long database of aerosol measurements over land, making possible new research into how air pollution changes affect climate change.
Using this new database, the researchers show that clear sky visibility over land has decreased globally over the past 30 years, indicative of increases in aerosols, or airborne pollution. Their findings are published in the March 13 issue of Science.
The advent of modern appliances such as washing machines and refrigerators had a profound impact on 20th Century society, according to a new Université de Montréal study. Plug-in conveniences transformed women's lives and enabled them to enter the workforce, says Professor Emanuela Cardia, from the Department of Economics.
When a single female is nearby, female antbirds will sing over the songs of their male partners in an apparent attempt to keep their messages from getting through, according to a new report published online on March 12th in Current Biology, a Cell Press publication. Males respond to that interruption by singing a different tune.
The findings offer the first evidence that such "signal jamming" and "jamming avoidance" occur between mates, according to the researchers.
New research suggests that a person's appearance may play a role in whether they are deemed trustworthy by financial lenders. The study is summarized in a working paper by Jefferson Duarte at Rice University's Jones Graduate School of Management and Stephan Siegel and Lance Young, both of the University of Washington.
Following a successful International Scientific Congress attended by more than 2,500 delegates from nearly 80 countries, preliminary messages were summed up. The conclusions will be published as a full report in June 2009. The conclusions were handed over to the Danish Prime Minister Mr. Anders Fogh Rasmussen today. The Danish Government will host the UN Climate Change Conference in December 2009 and will hand over the conclusions to the decision makers ahead of the Conference.
The six preliminary key messages are:
Key Message 1: Climatic Trends
Los Angeles, CA — Neighborhoods saddled with gangs fighting over the same turf suffer higher homicide rates and greater instability than areas where the gangs are scarce, according to a recent study by researchers at Charles Drew University of Medicine and Science.
The study—featured online this week in the Journal of Urban Health: Bulletin of the New York Academy of Medicine—examined how the presence of neighborhood street gangs influences homicides rates in communities throughout Los Angeles County.
As a teenager in the juvenile justice system, living in a single-parent household or having a family with criminal history doesn't help your case -- at least if you're a minority.
A study by social work researchers at Kansas State University found that circumstances like school truancy, living in a single-parent household or having family members with criminal records were more likely to land minority teens in detention than their white peers.
TALLAHASSEE, Fla. -- There is no question that the recent economic crisis has wreaked havoc on companies and on families across the country. Now, a recent study of 300 married, working couples conducted by Wayne Hochwarter, the Jim Moran Professor of Management at Florida State University's College of Business, is revealing just how deeply the crunch is being felt.
Washington, DC—A new study finds that Iowa reflects the diversity of America more than most other U.S. states and is well-placed to deserve its status as the first presidential nomination primary. In particular, Iowa is particularly typical of the U.S. in economic and social terms.
NEW BRUNSWICK, N.J. – Rutgers AIDS researchers Gail Ferstandig Arnold and Eddy Arnold may have turned a corner in their search for a HIV vaccine. In a paper just published in the Journal of Virology, the husband and wife duo and their colleagues report on their research progress.
Combating climate change may not be a question of who will carry the burden but could instead be a rush for the benefits, according to new economic modeling presented today at "Climate Change: Global Risks, Challenges & Decisions" hosted by the University of Copenhagen.
Contrary to current cost models for lowering greenhouse gas emissions and fighting climate change, a group of researchers from the University of Cambridge conclude that even very stringent reductions of can create a macroeconomic benefit, if governments go about it the right way.
The most ambitious independent policy review in the UK for over a decade is published this week and makes challenging reading for both Government and Opposition.
How has Britain progressed over the last decade? What are the next big choices that face us in the coming one?
Counting calories that burn through activity is a constant quandary.
One can only run on a treadmill so long, watching intently as the pedometer reads out the number of calories melted during a session of exercise. Not to mention the question of how many calories are burned through basic daily movements and even during sleep.
But technology – and youthful ambition – is presenting a round-the-clock solution for those consumed with this calculation.
AUSTIN, Texas—Wishful bettors, those who make overly optimistic investments, will ultimately harm themselves financially, but they can harm entire markets as well, new research shows.
LOS ALAMOS, New Mexico, March 11, 2009—Los Alamos National Laboratory scientists have produced the world's first Map of Science—a high-resolution graphic depiction of the virtual trails scientists leave behind when they retrieve information from online services. The research, led by Johan Bollen, appears this week in PLoS ONE (the Public Library of Science).
"This research will be a crucial component of future efforts to study and predict scientific innovation, as well novel methods to determine the true impact of articles and journals," Bollen said.
