Liquid detergent pods pose risks to children
October 7, 2014 03:30 PM - Elsevier Health Sciences via EurekAlert
Liquid laundry and dishwasher detergent pods are an emerging source of chemical exposure in children. When squeezed or bitten into, these pods can burst and send detergent into the mouth, nose, and eyes. A new report published in the current issue of the Journal of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) cautions that these products should be kept away from children because the bursting detergent pods can cause significant corneal injury. Detergent pods may offer a simpler way to do laundry, but they represent a source of potential danger when in the hands of a young child. Available in the European market for over a decade and first introduced to the American market in 2010, liquid detergent pods are brightly colored, which makes them attractive to young children who mistake them for toys.
How Yogurt Protects Us From Environmental Poisoning
October 7, 2014 08:58 AM - ClickGreen Staff, ClickGreen
Yogurt containing probiotic bacteria successfully protected children and pregnant women against poisoning from heavy metal exposure, according to a new study. Working with funding from the Bill and Melinda Gates Foundation, Canadian and Tanzanian researchers created and distributed a special yogurt containing Lactobacillus rhamnosus bacteria and observed the outcomes against a control group.
Sea Turtles in Hawaii getting tumors and we are the cause
October 7, 2014 08:09 AM - University of Hawai'i at Mānoa
Hawai'i's sea turtles are afflicted with chronic and often lethal tumors caused by consuming non-native algae, "superweeds," along coastlines where nutrient pollution is unchecked. The disease that causes these tumors is considered the leading cause of death in endangered green sea turtles. The new research was just published in the scientific journal PeerJ. Turtles that graze on blooms of invasive seaweeds end up with a diet that is rich in a particular amino acid, arginine, which promotes the virus that creates the tumors. Scientists at the University of Hawai'i at Mānoa and their NOAA colleague estimate that adult turtles foraging at high-nutrient grazing sites increase their arginine intake 17—26 g daily, up to 14 times the background level.
Fish may not adjust to rising CO2 levels quickly
October 6, 2014 04:29 PM - Oliver Milman The Guardian, Organic Consumers Association
Rising carbon dioxide levels in oceans adversely change the behavior of fish through generations, raising the possibility that marine species may never fully adapt to their changed environment, research has found. The study, published in Nature Climate Change, found that elevated CO2 levels affected fish regardless of whether their parents had also experienced the same environment.
Does the public trust what scientists say?
October 6, 2014 03:58 PM - Princeton University
If scientists want the public to trust their research suggestions, they may want to appear a bit "warmer," according to a new review published by Princeton University's Woodrow Wilson School of Public and International Affairs. The review, published in the Proceedings of the National Academy of Sciences (PNAS), shows that while Americans view scientists as competent, they are not entirely trusted. This may be because they are not perceived to be friendly or warm.
How Air Pollution Affects River-Flow
October 6, 2014 10:13 AM - ClickGreen Staff, ClickGreen
Air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere, according to the results of a new study. The paper shows how pollution, known as aerosols, can have an impact on the natural environment and highlights the importance of considering these factors in assessments of future climate change.
Lawrence Livermore finds ocean warming underestimated by past analyses
October 6, 2014 07:32 AM - Anne M Stark, LLNL
Using satellite observations and a large suite of climate models, Lawrence Livermore scientists have found that long-term ocean warming in the upper 700 meters of Southern Hemisphere oceans has likely been underestimated. "This underestimation is a result of poor sampling prior to the last decade and limitations of the analysis methods that conservatively estimated temperature changes in data-sparse regions," said LLNL oceanographer Paul Durack, lead author of a paper appearing in the October 5 issue of the journal Nature Climate Change.
What's best for creating drought resistant plants? Traditional breeding or GM?
October 5, 2014 08:29 AM - Lawrence Woodward, The Ecologist
Reports show that traditional breeding techniques are years ahead of GM technologies in developing crops to withstand drought and poor soils, writes Lawrence Woodward. Yet GM advocates are sticking rigidly to their script even as the evidence mounds against them. Since its launch in 2010, the Improved Maize for African Soils Project (IMAS) has developed 21 conventionally bred varieties which have increased yield by up to 1 tonne per hectare.
Rusty-Patched bumble bee "re-discovered" in Virginia state park
October 4, 2014 08:45 AM - Smithsonian Science
The rusty-patched bumble bee (Bombus affinis), which has not been seen in the eastern United States in five years, has been found by a Smithsonian Conservation Biology Institute research team at Sky Meadows State Park in Delaplane, Va. This formerly common bee has disappeared from 87 percent of its range in the Upper Midwest and Eastern Seaboard and is feared headed for extinction. The research team, led by Bill McShea and Tom Akre of the Smithsonian Conservation Biology Institute and T'ai Roulston from the University of Virginia, surveyed bee populations at 17 Virginia sites from May through August to study the influence of land management on bee diversity. Only one individual of this now rare species was found among nearly 35,000 bees belonging to 126 species collected and examined by the study.
US Pledges climate change planning assistance to developing countries
October 3, 2014 04:29 PM - Editor, SciDevNet
The United States will commit to significantly improving developing countries' access to data, tools and training to help them adapt to climate change, the US president told the Climate Summit in New York last week (23 September). Barack Obama pledged to immediately release higher resolution topographical data for Africa, to scale up a training programme to boost meteorologists’ ability to monitor and predict climate change, and to create a public-private partnership to put climate-relevant information and tools in the hands of developing world policymakers.
