Why Elephants Rarely Get Cancer
October 8, 2015 12:58 PM - University of Utah
Why elephants rarely get cancer is a mystery that has stumped scientists for decades. A study led by researchers at Huntsman Cancer Institute (HCI) at the University of Utah and Arizona State University, and including researchers from the Ringling Bros. Center for Elephant Conservation, may have found the answer.
Solar powered water purification
October 8, 2015 06:48 AM - Jennifer Chu | MIT News Office
Deep in the jungles of the Yucatan peninsula, residents of the remote Mexican village of La Mancalona are producing clean drinking water using the power of the sun.
For nearly two years now, members of the community, most of whom are subsistence farmers, have operated and maintained a solar-powered water purification system engineered by researchers at MIT.
The system consists of two solar panels that convert sunlight into electricity; these, in turn, power a set of pumps that push water through semiporous membranes in a filtration process called reverse osmosis. The setup purifies both brackish well water and collected rainwater, producing about 1,000 liters of purified water a day for the 450 residents.
Arsenic found in many US red wines
October 7, 2015 09:11 AM - Jennifer Langston, University of Washington
A new University of Washington study that tested 65 wines from America’s top four wine-producing states — California, Washington, New York and Oregon — found all but one have arsenic levels that exceed what’s allowed in drinking water.
The U.S. Environmental Protection Agency allows drinking water to contain no more than 10 parts per billion of arsenic. The wine samples ranged from 10 to 76 parts per billion, with an average of 24 parts per billion.
Are fish the greatest athletes?

When you think of the world’s greatest athletes, names like Usain Bolt generally spring to mind, but scientists have discovered the best athletes could well be found in the water, covered in scales.
It turns out that fish are far more effective at delivering oxygen throughout their body than almost any other animal, giving them the athletic edge over other species.
Noise pollution harms wildlife, degrades habitats
October 5, 2015 09:11 AM - Shreya Dasgupta, MONGABAY.COM
Traffic noise is just another inconvenience for many of us. But for wildlife, noise from honking, and zooming vehicles can often be an insidious threat: it can degrade habitats without leaving any physical evidence of change, warns a recent study published in the Proceedings of the National Academy of Sciences.
Road noise — even in moderate levels — pushes migrating birds away from their stopover habitats, researchers from Boise State University in Idaho found. Those that stay back become weak.
“I was initially surprised that even moderate road noise — comparable to a suburban setting — would have such a wide-ranging impact on migrating birds,” William Laurance, a professor at James Cook University in Cairns, Australia, who was not involved in the study, told Mongabay. “On reflection, however, I guess such migrators have to be hyper-vigilent about noise, as they’re constantly moving to new areas where unseen predators could be lurking.”
EU Health Forum considers crisis the new normal
October 5, 2015 07:00 AM - EurActiv
After nearly a decade of economic crisis, an Ebola epidemic in West Africa, and a refugee crisis, experts say that EU health systems must get used to the fact that "shockwaves" are here to stay.
They hope that the Ebola outbreak will be a wake up call, that, without stronger European leadership, healthcare in the EU will come under many threats.
At the European Health Forum Gastein (EHFG) on Thursday (1 October), DEVCO, the European Commission's Directorate-General for International Cooperation and Development, hosted a forum dealing with how to secure health in the EU through development work and international cooperation.
The Gypsies problem in Europe
October 4, 2015 07:34 AM - Dan Allen, University of Salford, The Ecologist
Under new planning rules, Travellers and Gypsies must be able to prove they are actually traveling to qualify for limited planning benefits to create new sites. But for many, it's impossible to do that. Not only to remain in employment, or education - but precisely because there are so few sites, that they are unable to travel.
Living on an unauthorised campsite carries a heavy weight of suffering and disadvantage. Travellers contend daily with the risk of criminalisation and eviction, as well as limited access to basic services such as running water and sanitation.
Any attempt to subsume diverse groups under one label is going to be fraught with tension - and this is certainly true in terms of the word 'Traveller'.
Antibacterial vs. Plain Soap
October 2, 2015 08:27 AM - Dr. Mercola, Organic Consumers Association
A survey by the American Cleaning Institute and the industry-run Personal Care Products Council revealed that 74 percent of Americans use antibacterial soap.
Fifty-six percent of them use it regularly, and, reportedly, 75 percent of moms with children in the household said they would be “angry” if antibacterial soap was no longer on the market.
Do you favor hotels that ask you to reuse your towels?
October 2, 2015 06:40 AM - ClickGreen staff, ClickGreen
Hotels across the globe are increasingly encouraging guests to embrace green practices. Yet while guests think they are supporting the environment by shutting off lights and reusing towels, they may in fact be victims of "greenwashing," a corporation's deceitful practice of promoting environmentally friendly programmes while banking the extra profits.
Greenwashing practices, such as a sign that reads "save the planet: re-use towels," coupled with claims of corporate social responsibility, have soiled the trust of American consumers who are increasingly recognizing hotels' green claims may be self-serving. This could cause hotels to lose valuable repeat customers.
Cancer drug found to sharpen memory, potential for Alzheimer's treatment
October 2, 2015 06:13 AM - Robin Lally, Rutgers University
Can you imagine a drug that would make it easier to learn a language, sharpen your memory and help those with dementia and Alzheimer’s disease by rewiring the brain and keeping neurons alive?
People with a dementia such as Alzheimer's disease lose their memory when brain cells shrink and die because connections can no longer transfer information.
New Rutgers research published in the Journal Neuroscience found that a drug – RGFP966 – administered to rats made them more attuned to what they were hearing, able to retain and remember more information, and develop new connections that allowed these memories to be transmitted between brain cells.
