How to help your brain age more slowly
April 25, 2015 08:16 AM - Laura Kurtzman, University of California San Francisco
Brains age, just like the rest of the body, even for those don't get neurological disease, according to an Institute of Medicine.
"Some of the changes that one observes doesn't mean that it's all over, gloom and doom," the committee’s vice chair, Kristine Yaffe, MD, told the Washington Post.
”‹While aging does more damage to some than others, most people can take steps to improve their health, according to Yaffe, the Roy and Marie Scola Endowed Chair and professor of psychiatry, neurology, and epidemiology at UCSF and chief of geriatric psychiatry and director of the Memory Disorders Clinic at the San Francisco VA Medical Center.
A brief history of Earth Day
April 22, 2015 09:59 PM - Earth Day Network
Each year, Earth Day -- April 22 -- marks the anniversary of what many consider the birth of the modern environmental movement in 1970.
The height of hippie and flower-child culture in the United States, 1970 brought the death of Jimi Hendrix, the last Beatles album, and Simon & Garfunkel’s “Bridge Over Troubled Water”. Protest was the order of the day, but saving the planet was not the cause. War raged in Vietnam, and students nationwide increasingly opposed it.
Energy-tracking app encourages sustainable behaviors
April 22, 2015 01:33 PM - Editor, ENN
We've all heard of fitness trackers and apps that help us stay on track with our daily nutrition and exercise, but what about an app to monitor our personal energy usage and carbon footprint? Just in time for Earth Day, a team at the University of Wisconsin-Madison has created an energy-tracking app to make reducing day-to-day energy usage more accessible.
US leads the world in EV adoption
April 21, 2015 03:38 PM - ClickGreen Staff, ClickGreen
The United States currently leads the world in the number of plug-in electric vehicles on the road, capturing 41% of the global market. Though the market can be traced back to the early-to-mid 1990s with the release of the Chrysler TEVan and the General Motors EV1, it wasn’t until the second wave of vehicles such as the Nissan Leaf and the Chevrolet Volt, both introduced in 2010, that plug-in electric cars started to become a success in the US.
It was Tesla Motors with its Roadster series which first entered production in 2008 that reignited this interest in the market though. The small company was founded by Martin Eberhard and Marc Tarpenning in 2003 before current CEO Elon Musk joined the company the following year and led the business to new heights with links to new battery technologies that made plug-in electrical vehicles a more viable option for everyday journeys.
Side effects of Statin drugs may be underestimated in elderly patients
April 21, 2015 07:30 AM - Elizabeth Fernandez, University of California San Francisco
A new study by UC San Francisco has found that statins can help prevent disease in older adults but must be weighed against potentially serious side effects.
Amid a projected cost of almost $900 billion for cardiovascular disease over the next decade in the U.S., statins are used by nearly half the elderly population in the nation. But in spite of the widespread use, there has been little systematic scrutiny of the potential risks of the drugs in older adults and whether those side effects could offset cardiovascular and other health benefits.

France is leading Europe’s electric vehicle revolution with the nation now accounting for more than a quarter of EV sales across the EU, new figures reveal.
Data released by the European Environment Agency shows around 38 000 electric vehicles were registered in 2014, up by 57 % compared to 2013.
Lake Mead water levels continuing to drop
April 19, 2015 07:45 AM - Kirk Siegler/NPR
The historic four-year drought in California has been grabbing the headlines lately, but there's a much bigger problem facing the West: the now 14-year drought gripping the Colorado River basin.
One of the most stunning places to see its impact is at the nation's largest reservoir, Lake Mead, near Las Vegas. At about 40 percent of capacity, it's the lowest it's been since it was built in the 1930s.
Human sweat conveys our emotional state!
April 16, 2015 06:50 AM - ASSOCIATION FOR PSYCHOLOGICAL SCIENCE via EurekAlert.
Humans may be able to communicate positive emotions like happiness through the smell of our sweat, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research indicates that we produce chemical compounds, or chemosignals, when we experience happiness that are detectable by others who smell our sweat.
While previous research has shown that negative emotions related to fear and disgust are communicated via detectable regularities in the chemical composition of sweat, few studies have examined whether the same communicative function holds for positive emotions.
How California distributes scarce water
April 15, 2015 08:09 AM - Dan Charles, NPR
The state of California is asking a basic question right now that people often fight over: What's a fair way to divide up something that's scarce and valuable? That "something," in this case, is water.
There's a lot at stake, including your very own nuts, fruit and vegetables, because most of the water that's up for grabs in California goes to farmers. This year, some farmers will get water, and others will not, simply based on when their land was first irrigated.
Consider, for instance, the case of Cannon Michael. He grows tomatoes and melons in California's Central Valley. And despite the drought, he'll still grow them this year.
Lifecycle of Today's Cell Phone
April 7, 2015 08:57 AM - ClickGreen Staff, ClickGreen
It is estimated that in 2014 over two billion mobile phones were sold worldwide. Of these, over one billion were estimated to be smartphones. It is also estimated that a massive 87% of the world’s population now use mobile phones. These are staggering figures, but how many of us have ever stopped to think of where our precious mobile phones came from and what happens to them once we discard them for a newer model?
Each year millions of mobile phones are produced in the world and an equal number are disposed of. In the vast majority of cases these discarded phones work perfectly well. However, like all technological products these days, phones have a built-in technological obsolescence (we demand the latest model or the latest upgrade) as well as a built in aesthetic obsolescence (we demand the latest style or design).
In spite of their extremely small size and simplicity of look, mobile phones are immensely complex pieces of technology with many, many components. If we stop to think about it for a moment all of these products need sourcing: the raw materials needed to produce them need extracting from the ground, these need to manufactured into working parts which are then assembled into the final phone.
