The Secret to Writing Well Isn't What You'd Expect, Says Study - 0 views

  • 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.
  • And perhaps more importantly, write often. If creative writing is a skill your brain learns over time, then like anything else, the more you practice, the better you’ll get.

    The important part of the finding is that writing is a skill that one can master over time.  While I agree with Stephen King in the sense that great writers can not be created, I also agree that anyone can become a decent writer.

  • 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.

New, inexpensive production materials boost promise of hydrogen fuel (Feb. 21, 2014) - 0 views

2014 production hydrogen fuel LL-Pub

  • 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.
  • "In order to make commercially viable devices for solar fuel production, the material and the processing costs should be reduced significantly while achieving a high solar-to-fuel conversion efficiency," says
  • Choi and postdoctoral researcher Tae Woo Kim combined cheap, oxide-based materials to split water into hydrogen and oxygen gases using solar energy with a solar-to-hydrogen conversion efficiency of 1.7 percent, the highest reported for any oxide-based photoelectrode system.

  • "Without fancy equipment, high temperature or high pressure, we made a nanoporous semiconductor of very tiny particles that have a high surface area," says Choi, whose work is supported by the National Science Foundation. "More surface area means more contact area with water, and, therefore, more efficient water splitting."
  • "Since no one catalyst can make a good interface with both the semiconductor and the water that is our reactant, we choose to split that work into two parts," Choi says. "The iron oxide makes a good junction with bismuth vanadate, and the nickel oxide makes a good catalytic interface with water. So we use them together." The dual-layer catalyst design enabled simultaneous optimization of semiconductor-catalyst junction and catalyst-water junction.
  • In a study published last week in the journal Science, Choi and postdoctoral researcher Tae Woo Kim combined cheap, oxide-based materials to split water into hydrogen and oxygen gases using solar energy with a solar-to-hydrogen conversion efficiency of 1.7 percent, the highest reported for any oxide-based photoelectrode system.

    I am an advocate of switching to hydrogen for combustion engines.  One of the best reasons is that combustion produces water.  Furthermore, it is much safer than most people believe.  (Your car is not going to turn into the Hindenburg.) In Ben Bova's Book "Break Throughs" he talked of huge floating solar powered hydrogen producing plants.  In Room's "The Hype About Hydrogen" he painfully points out that H2 production is still not cost effective enough to complete with Gasoline.  That said, research like this leaves us hope for the future.

Sperm can pass trauma symptoms through generations, study finds | The Verge - 0 views

2014 trauma inheritance physiology psychology medicine research LL-Pub

  • People who experience early childhood trauma, like abuse or war, often exhibit a number of hormonal imbalances. The mechanisms involved are poorly understood, but most scientists agree that traumatic events alter gene expression, which then causes misregulations in a number of biological processes. But whether these changes can actually be passed down to offspring is a controversial question, because it would imply that acquired traits — traits that aren't actually encoded in DNA, but rather arise following certain experiences — are somehow being passed down through generations.
  • 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

    An interesting article on how trauma may be handed down but not by psychological transference nor DNA but by some other means of physiology. In other words, it is neither handed down from environment nor DNA.

  • Tetrahydrocannabinol, or THC, the active psychedelic ingredient in cannabis, has known anti-tumoral effects, Donald P. Tashkin, M.D., a pulmonologist at UCLA who has studied marijuana for more than 30 years, told weather.com. “It’s been shown by a large number of investigators to [reduce] growth of brain, lung, breast, prostate and thyroid cancer cells in animal models,” he said.

  • 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.

  • There is “absolutely no comparison” between the safety of marijuana and tobacco smoke, Dr. Tashkin added, noting that the latter is the top cause of preventable deaths in the United States. No one has ever overdosed on marijuana, and no major studies have found a significant increase in lung cancer risk from the drug.
