Air pollution found harmful to young brains
September 15, 2014 04:19 PM - University of Montana via EurekAlert
Findings by University of Montana Professor Dr. Lilian Calderón-Garcidueñas, MA, MD, Ph.D., and her team of researchers reveal that children living in megacities are at increased risk for brain inflammation and neurodegenerative changes, including Alzheimer’s or Parkinson’s disease. Calderón-Garcidueñas’ findings are detailed in a paper titled "Air pollution and children: Neural and tight junction antibodies and combustion metals, the role of barrier breakdown and brain immunity in neurodegeneration."
Japan: 'solar islands' replace nuclear power
September 15, 2014 08:41 AM - Jon Major, The Ecologist
As Japan seeks to end reliance on nuclear power, one of the answers is floating 'solar islands', writes Jon Major. A 70MW solar island opened last year, and two additional plants have just been announced. Two companies in Japan recently announced they are to begin building two large solar power islands that will float on reservoirs.
Most Polluted Countries
September 15, 2014 07:38 AM - Lizabeth Paulat, Care2
The WHO has released a new study ranking countries with the worst air pollution. When we consider air pollution most of us will automatically think of China. However, it was nowhere to be found in the top 10 offenders. This, by the way, is not because they’ve suddenly cleaned up their act, but rather because this study ranked countries as a whole, rather than cities. So here are the top 5 countries with the worst air pollution, and what they are trying to do to combat it. 1. Pakistan Pakistan made #1 on the list with a PM 2.5 pollution level of 101 ug/m3. Now, that might not make sense so let me break it down: PM 2.5 stands for the size of the particles of pollution. The size (2.5) is frequently cited as the most detrimental because it can travel deep into lungs and cause a variety of ailments. Good examples of these particles are smoke, mold and dust. The ug/m3 part stands for micrograms per unit meter of air. So Pakistan has 101 micrograms of PM 2.5 pollutants per unit meter of air.
Clouds of water found on "near" planet
September 14, 2014 07:32 AM - Ken Croswell, Science
Astronomers have found signs of water ice clouds on an object just 7.3 light-years from Earth-less than twice the distance of Alpha Centauri, the nearest star system to the sun. If confirmed, the discovery is the first sighting of water clouds beyond our solar system. The clouds shroud a Jupiter-sized object known as a brown dwarf and should yield insight into the nature of cool giant planets orbiting other suns. Kevin Luhman, an astronomer at Pennsylvania State University, University Park, recently discovered the nearby object by using images from NASA’s WISE infrared space telescope, which scanned the sky from 2010 to 2011. A brown dwarf is a failed star and has so little mass that it can't sustain nuclear reactions, so after its birth it fades and cools. This brown dwarf, named WISE J0855-0714, is the coldest known. Its temperature is slightly below the freezing point of water, so it's colder than Earth's mean temperature but warmer than Jupiter’s.
Australia to end shark cull
September 13, 2014 08:59 AM - Alicia Graef, Care2
In a major win for sharks and their advocates, Australia’s Environmental Protection Agency (EPA) has recommended Western Australia (WA) end its controversial shark killing program. After a series of fatal attacks, WA's government proposed a new program in an effort to keep beachgoers safe that involved setting out baited drum lines, which consist of a large baited hook attached to a buoy and an anchor to hold it in place, in designated zones along popular beaches with the intention of killing great white sharks, bull sharks and tiger sharks who were larger than three meters.

If you live in one of the visible areas on this map, you may be in for a treat tonight! According to AccuWeather.com, the solar flares of the Northern Lights are ranked as an X-class tonight, the highest class for a solar flare which may make the Northern Lights display as far south as Maryland on the East Coast, and as far down as Nebraska, further west.
Family pets are prey for Leopards in India
September 12, 2014 09:18 AM - WIldlife Conservation Society
A new study led by the Wildlife Conservation Society reveals that in India's human dominated agricultural landscapes, where leopards prowl at night, it's not livestock that’s primarily on the menu — it is man's best friend. The study, which looked at scat samples for leopards in India's Ahmednagar’s district in Maharashtra, found that 87 percent of their diet was made up of domestic animals. Domestic dog dominated as the most common prey item at 39 percent and domestic cats were second at 15 percent.
California Drought: Why Farmers Must Adapt
September 12, 2014 08:40 AM - Gina-Marie Cheeseman, Triple Pundit
The entire state of California is in a drought. A big part of the state, including the fertile Central Valley, is experiencing the worst category of drought, exceptional. California supplies much of the fruits, vegetables and nuts the nation eats. In inland areas such as the Central Valley, as well as the combined Sacramento and San Joaquin valleys, agriculture truly rules.
Why It's Important to Rinse Recyclables
September 11, 2014 12:38 PM - S.E. Smith, Care2
We all know it's important to recycle and not toss things into the trash or the environment, but how carefully do we need to rinse containers before sending them on their way to the recycling center? Some argue that recycling is a total waste of water when you factor in the amount people are using to get their cans, bottles, and jars squeaky-clean, while others claim containers don't need to be rinsed at all, and some say that the reality lies in the middle ground.
Disc or Download: A Virtual Energy-Savings Debate
September 11, 2014 11:20 AM - Winfield Winter, ENN
One of the best ways to spark an energy revolution is through the younger generation — and nothing quite speaks their language like video games. But this issue has less to do with the content of these addictive games and more with how the younger generation consumes them. Fantasy and adventure, sci-fi and first-person shooters, strategy and racing — video games today comes in all types of genres with thousands of add-ons and customizable features to make each story a virtual reality. And with all of these choices comes two more: buy a copy of the video game on a disc or download the video game straight from the console?
