Turkey might be a better choice than fish in the tropics!
November 27, 2014 07:12 AM - Katie Pitz in Oceanus: Woods Hole Oceanographic Institution.

On a tropical island vacation, one of the last things you want to worry about is food poisoning. Yet for many, a trip to the tropics includes a painful education in a mysterious food-borne illness called Ciguatera Fish Poisoning, or CFP.

Every year, thousands of people suffer from CFP, a poisoning syndrome caused by eating toxic reef fish. CFP symptoms are both gastrointestinal and neurological, bringing on bouts of nausea, vomiting, diarrhea, headaches, muscle aches, and in some cases, the reversal of hot and cold sensations. Some neurological symptoms can persist for days to months to years after exposure. There is no quick way to test for the toxins, and unless action is taken within hours of the poisoning, no cure once you’re sick.

Think Geoengineering is a quick fix for global warming?
November 26, 2014 09:20 AM - University of Bristol

The deliberate, large-scale intervention in the Earth’s climate system is not a “quick fix” for global warming, according to the findings of the UK’s first publicly funded studies on geoengineering.

The results of three projects – IAGP, led by the University of Leeds; SPICE, led by the University of Bristol; and CGG, led by the University of Oxford – are announced at an event held at The Royal Society, London, on 26 November.

Europe's Plastic Bag Agreement Contested by Industry
November 26, 2014 09:14 AM - Ecaterina Casinge, EurActiv

As lawmakers reached agreement this week to limit the use of plastic bags across Europe, industry voices warned that such rules will have a negative impact on trade in Europe's internal market. The ban could also lead to different standards in legislation in member states and ultimately, to a ban on other types of packaging, according to PlasticsEurope, the association of plastics manufacturers. The European Parliament and the Council agreed on Friday (21 November) on EU-wide legislation obliging member states to reduce the use of plastic bags. The law will apply only to bags with a thickness below 0.05mm, because they are less reusable, and turn into waste more quickly.

How the environment can trigger disease

Using a new imaging technique, National Institutes of Health researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecules trigger cell death that produces some human diseases, according to the researchers. The work provides a possible explanation for how one type of DNA damage may lead to cancer, diabetes, hypertension, cardiovascular and lung disease, and Alzheimer’s disease.

Establishing marine protected areas to fight illegal fishing
November 25, 2014 09:10 AM - Kerry Klein, MONGABAY.COM

Do you know how that tuna sashimi got to your dinner plate? Probably not—and chances are, the restaurant that served it to you doesn’t know, either. A new policy paper argues that illicit fishing practices are flying under the radar all around the world, and global society must combat them in order to keep seafood on the menu. According to the paper, published in Science, fishing practices that are illegal, unreported and unregulated (collectively referred to as IUU) are ubiquitous. They range from bottom trawlers scouring the seafloor—sometimes catching more illegal species than legal ones—to small boats simply not reporting their catch.

Climate change, species extinctions and tipping points
November 25, 2014 07:35 AM - North Carolina State University via EurekAlert.

Researchers from North Carolina State University have created a model that mimics how differently adapted populations may respond to rapid climate change. Their findings demonstrate that depending on a population's adaptive strategy, even tiny changes in climate variability can create a "tipping point" that sends the population into extinction.

Carlos Botero, postdoctoral fellow with the Initiative on Biological Complexity and the Southeast Climate Science Center at NC State and assistant professor of biology at Washington State University, wanted to find out how diverse populations of organisms might cope with quickly changing, less predictable climate variations.

Hope for the Monarch Butterfly
November 24, 2014 03:59 PM - Imogen Mathers, SciDevNet

When millions of monarch butterflies take to the sky and fly thousands of kilometres from the United States and southern Canada to Mexico, the view is breathtaking. But over the last few decades, their numbers have plummeted, and last year hit an all-time low. Illegal logging in Mexican forests, where the monarchs hibernate during winter, has traditionally been to blame. But large-scale logging by companies appears to have been halted. And now small-scale logging by local people for firewood and timber — a “growing concern in 2013” — has also stopped, according to a study published last month (27 October) in Biological Conservation.
