Taming the Butterfly

The gap between Democrats and Republicans who believe global warming is happening increased 30 percent between 2001 and 2010 - a "depressing" trend that's essentially keeping meaningful national energy policies from being considered, argues sociologist Aaron M. McCright.

Chinese hackers temporarily brought down the world's fastest-growing social action platform after more than 90,000 people in 175 countries endorsed an online call for the release of internationally acclaimed Chinese artist Ai Weiwei. Weiwei, best known for his role in the construction of the Beijing Olympic stadium and his recent Sunflower Seeds exhibition at the Tate Modern, has become an increasingly outspoken critic of the Chinese government in recent years, in particular over the handling of the 2008 earthquake in the country's Sichuan province.

The US government on Tuesday approved a plan to build the country's first offshore wind farm, in a picturesque bay near Cape Cod, a popular Massachusetts holiday destination.

Going the farthest distance might sound like a foot race. But this past weekend, it meant stretching the boundaries of fuel efficiency as student teams competed in the fifth annual Shell Eco-marathon Americas, a challenge for students to design, build and test fuel-efficient vehicles that travel the farthest distance using the least amount of energy. High school and university students from Canada and the United States competed in the two-day street course challenge in downtown Houston.

thanks to a research project that is the next best thing to time travel, DeJong is measuring the duck eggs in several museum collections - from the Smithsonian Institution, in this case, where Bendire was the first curator of the discipline known as oology, or the study of birds' eggs. When her project is done, DeJong will have assembled and analyzed a metrics database on perhaps 60,000 duck eggs representing at least 40 species and subspecies of ducks found in North America.

The gamitana fish, a close relative of the flesh-eating piranha, mostly eats fruit and can carry seeds down the Amazon River as far as 3 miles (5 kilometers), reports a new Cornell study, making it one of the longest seed dispersals ever reported. The researchers report that these fish (Colossoma macropomum, known as gamitana in Peru, and tambaqui in Brazil) may play an important role in the structure of the Amazon forest as fruit seeds remain viable in their gut for many days and are widely spread.

In the wake of several highly publicized suicides by gay teenagers, a new study finds that a negative social environment surrounding gay youth is associated with high rates of suicide attempts by lesbian, gay, and bisexual (LGB) youth. The study, "The Social Environment and Suicide Attempts in a Population-Based Sample of LGB Youth," appears in the April 18 issue of Pediatrics. It was conducted by by Robert Wood Johnson Foundation Health & Society Scholar Mark L. Hatzenbuehler at Columbia University's Mailman School of Public Health.

Policymakers are very familiar with land-use planning. But what is the best approach for planning uses of America's coastal waters and oceans? That question has gained importance since President Obama formed the National Ocean Council last summer and charged it with developing an ecosystem-based stewardship policy for the nation's oceans, coastal waters and the Great Lakes.

Back in 2009 Mayor Bloomberg prohibited vehicle traffic on Broadway between 42nd Street and 47th Street in Times Square to create a pedestrian plaza (video here). Now, the city's most recent Community Air Survey found that, "After the conversion to a pedestrian plaza, NO pollution levels in Times Square went down by 63 percent while, NO2 levels went down by 41 percent." Unlike N2O, which makes you laugh at Phish shows, NO2, or nitrogen dioxide, destroys your lungs and may cause Sudden Infant Death Syndrome. Nitric oxide (NO) isn't good for you either.

The first research to actively analyze adult male sea turtles (Caretta caretta) using satellite tracking to link geography with pollutants has revealed the potential risks posed to this threatened species by manmade chemicals. The research, published today in Environmental Toxicology and Chemistry, examines the different levels of chemicals in the blood of both migratory and residential turtles.

The United States cannot rule out another oil disaster in its waters, the official who led the response to last year's Gulf of Mexico spill told AFP, as the country marks one year since the tragedy.

The European Union's Working Party on Data Protection has issued five recommended requirements for the protection of personal privacy in a time of Smart Meters in the home (PDF). Below is what the group says needs to happen in order to gain the benefits of Smart Metering data while minimizing the risk and cost to personal privacy. 

Daily temperature fluctuations, not just high temperatures, play a significant role in the transmission of dengue, a deadly mosquito-borne disease that strikes millions of people in tropical and subtropical countries, according to ground-breaking research led by French, Thailand and U.S. scientists and conceived by medical entomologist Thomas Scott of the University of California, Davis.

he car of the future could be propelled by a fuel cell powered with hydrogen. But what will the fuel tank look like? Hydrogen gas is not only explosive but also very space-consuming. Storage in the form of very dense solid metal hydrides is a particularly safe alternative that accommodates the gas in a manageable volume. As the storage tank should also not be too heavy and expensive, solid-state chemists worldwide focus on hydrides containing light and abundant metals like magnesium.

Sarah Saurer was seven years old when she was diagnosed with brain cancer. Her parents soon found out that several other children in their small town -- which sat just miles away from two troubled Illinois nuclear power plants -- had been diagnosed with brain cancer and leukemia. Then news broke that one of the plants had been leaking radioactive water for years before it was detected. A quick survey by concerned mothers found that every single home within a quarter mile of the spill housed someone who'd been diagnosed with cancer. "I want to remind you how important it is to protect people from the harmful things that are being put into our environment," Sarah Saurer told the scientists, her short stature and child-like face showing little sign of her 17 years.

Thousands of hectares of tropical dry forests in the Brazilian state of Minas Gerais are now safe from logging, thanks to scientists affiliated with a project called Tropi-Dry.

Increases in temperature as a result of climate change are mirrored in lake waters where temperatures are also on the rise. A new study, by Dr. Martin Dokulil, retired researcher from the Institute for Limnology at the University of Innsbruck in Austria, forecasts surface water temperatures in large Austrian lakes for 2050 and discusses the impact on the lakes' structure, function and water quality. The research is published online in Springer's journal Hydrobiologia.

"Bicyclean, a pedal-powered grindstone that pulverizes entire circuit boards inside a polycarbonate enclosure, capturing the dust. Though Field is now a year out of college, her project recently won the silver award at the Acer Foundation's Incredible Green Contest in Taiwan and was displayed for three days at COMPUTEX Taipei, one of the world's largest computer industry expositions. The $35,000 prize will enable her to return to Ghana to test a second-generation prototype and to seek non-profit status for the endeavor, a significant milestone in a project she was afraid might fall by the wayside after graduation."

"Dendrochronologists have shown that tree-ring data produce a remarkably accurate history of droughts and other climate changes. Combined with reliable drought indices and historical descriptions of climate conditions, dendrochronology - the technique of dating events and environmental change by relying on characteristic patterns of tree-ring growth - can provide a climate perspective on important events such as large-scale human migration and even the rise and fall of entire civilizations."
