The trouble with solar fuel production is the cost of producing the sun-capturing semiconductors and the catalysts to generate fuel. The most efficient materials are far too expensive to produce fuel at a price that can compete with gasoline.

After the pups of the traumatized male mice were born, scientists monitored their behavior. As expected, these pups showed the same symptoms of trauma that their fathers did, despite having never undergone traumatic events themselves. And these symptoms were even apparent in a third generation of mice.

When researchers looked at the sperm of the traumatized mice, they discovered that the microRNAs in these sperm cells were also present in abnormally high numbers. "This means that germ cells — sperm in males and oocytes in females — are very sensitive to environmental conditions in early life," Mansuy says, "and early childhood trauma has consequences not only for the brain but also for the germ cell line

Search, and Google in particular (with 90% of worldwide share), still drive vastly greater quantities of traffic than all the social networks combined (some good research from DefineMG here). Given Google’s 3.5+ Billion searches performed each day, that shouldn’t be a surprise, but to many bloggers, thinking about search, Google, and all that “SEO stuff” has been put aside in favor of Facebook shares, likes, tweets, +1s, and the more visible feedback and applause that come from social sources.

Thankfully, you can resolve to make this a priority in the future. It may sound like a bad infomercial, but you can substantially upgrade your blog’s SEO potential with less than 5 minutes per post. Here’s how:

The other keyword research source I’d encourage you to pursue is Google’s autosuggest.

I’m a freelancer, but I have a couple of contract gigs that play a big role in my monthly and daily cycles. I’m the science editor at BoingBoing.net, a technology and culture blog with 6 million monthly readers. I also have a monthly column with The New York Times Magazine.

The rest of the day really varies a lot, depending on what I have on my plate at that given time. I have ADHD and it’s really easy for me to get distracted and be unproductive, so I have lots of little tricks I rely on to keep me focused throughout the day. I used to use a timer on my computer a lot, just to have something that, periodically, forced me to look up and think about what I was doing and what I had to do next. But I find now that the two hours between breast pump sessions actually does that job pretty well. I also jump back and forth between stuff on my to-do list, depending on what I feel motivated to do. If I just can’t get myself to write during a given two-hour block, I’m better off answering email or sending out interview requests than just sitting there, staring at a blank page.

But research on its long-term medical effects — and its impact on healthy individuals — has been hampered by the federal government’s stance on its legality, he continued. “Pharmaceutical development has been thwarted by the federal government’s seeming unwillingness to have new scientific discovery supplant long-standing ideology.”

ut research shows it can exacerbate mental health problems, such as bipolar disorder and schizophrenia, in people with a predisposition for these conditions.

Some marijuana experts, like Mayo’s Bostwick, think this tight regulation is harmful because all the marijuana used in studies come from the same place — whereas in the real world, the plants can vary widely, leading to different effects for different people.

Extremely low doses of THC may protect the brain from long-term cognitive damage in the wake of injury from a lack of oxygen, seizures or toxic drugs, one study in mice published in the journal Experimental Brain Research found.Another mouse study concluded that CBD might help stop alcohol-related brain damage.

According to research published by Viacom TV Everywhere users show an increase in overall TV viewing, as well as greater customer loyalty towards pay TV providers that offer TV Everywhere services.

Online surveys were conducted with more than 1,300 Viacom viewers ages 13-49 and more than 600 kids ages 2-12. Participants included both users of TV Everywhere and non-users.

The majority of users agree: TV Everywhere is additive to the TV viewing experience. Since they began using TV Everywhere apps and sites, 64% report watching more TV overall. This finding is even stronger among Millennials, with 72% watching more TV.

While visualizing your story may seem like the right way to approach writing, it turns out that for full-time writers, the brain performs a bit differently. When Dr. Lotze watched writers from a competitive creative writing program perform the same tests, he found that experienced writers, while brainstorming, used parts of their brains associated with speech instead of vision.

Novice writers, Lotze suggests, are more likely to watch the story unfold like a movie inside their heads.
