Five-step plan for green design
by sciencebase in Sciencebase Science Blog
I recently saw a research paper discussing the lack of tools for designers hoping to make their products greener, more environmentally benign, sustainable even. The paper focused more on the likes of coming up with a green espresso machine and offered a five-step scheme for getting the green credentials booked into a the design and [...]Five-step plan for green design is a post from: Sciencebase Science Blog

In which I serve up a big fattie for my self-perceived critics
by DrugMonkey in DrugMonkey
There is an interesting paper that I just ran across which will possibly please a certain segment of my audience. You see, it provides a bit of a test of the hypothesis frequently bandied by my commenters that anti-drug messages backfire. That if you tell adolescents all sorts of bad things are going to happen to them if they try an illicit drug once, and it doesn't happen, somehow you are actually encouraging them to try the drug again. This general area is an occasional interest of mine and yo........ Read more »

Deep Brain Stimulation for Schizophrenia?
by Dr Shock in Dr Shock MD PhD
In short, a recent article proposed to do deep brain stimulation for schizophenia. Schizophrenia has positive-, negative- and cognitive symptoms (see the figure above). The authors propose the DBS for positive symptoms. Their approach is based on current models of the neurocircuitry of psychosis .
They hypothesize:
that chronic, high frequency electrical stimulation (HFS) of [...]

The ecosystem services balancing act
by Paul Spraycar in Beyond Climate Change
A recent paper in Ecology Letters, “Understanding relationships among multiple ecosystem services,” addresses the relationship among multiple ecosystem services at a single site, addressing in particular one consequence of maximizing one ecosystem service: other services often decline substantially.
Despite growing interest in ecosystem services, the authors contend that much of the research literature is limited by only considering a single ecosystem service, or at most two service........ Read more »

Switchable DNA nanostructures for Energy and Data Storage
by Olexandr Isayev in olexandrisayev.com
The Brookhaven team, has been refining techniques to use strands of artificial DNA as a highly specific kind of Velcro or glue to link up nanoparticles. Such DNA-based self-assembly holds promise for the rational design of a range of new materials for applications in molecular separation, electronics, energy conversion, and other fields. But none of these structures has had the ability to change in a programmable manner in response to molecular stimuli — until now. “Now we’re u........ Read more »

The Brain in CRPS-More Barriers or New Opportunities
by Lorimer Moseley in BodyInMind
From a biological perspective, I find CRPS very perplexing. So do many other people—the community of scientists that are pursuing better treatments, through a better understanding of the basic mechanisms, or by developing better animal models of CRPS, or by undertaking clinical investigations and clinical trials, stretches across many countries and many scientific and clinical disciplines. With all of those supposedly clever people working on it, one might expect that by now [........ Read more »

The extended twilight of the mammoths
One of Charles R. Knight's wonderful paintings of woolly mammoths walking through the snow of ancient Europe. On display at the Field Museum in Chicago.
When did the last woolly mammoths die?
There is no easy answer to the question. In its heyday the woolly mammoth (Mammuthus primigenius) was distributed across much of the northern hemisphere, from southern Spain to the eastern United States, and the entire species did not simply lay down and die at one particular moment. Some populations........ Read more »

The Truth About Organic Farming
by Christie Wilcox in Nutrition Wonderland
In the past year or two, certified organic sales have jumped around 30% to about $52 billion (2008 dollars) worldwide despite the fact that organic foods cost up to three times as much as those produced by conventional methods. More and more, people are shelling out their hard-earned cash for Certified Organic. Imagine, people say: you can improve your nutrition while helping save the planet from the evils of conventional agriculture – a complete win-win. And who wouldn’t buy organic........ Read more »

Cancer genomes
by Joe Dunckley in Cotch
Since sequencing the human genome, the Sanger Institute in the UK and the US National Human Genome Research Institute have turned their sights -- and their vast sequencing capacities -- to cancer. Cancers can be thought of as genomic diseases, caused by somatic mutations, and progressing by the accumulation of further mutations. Last week, Nature published online the papers describing two new cancer genomes, bringing the total number of human cancer genome sequences published to five...... Read more »
