The research and development of biofuels is beginning to attract investment from large international companies, including those traditionally associated with their fossil fuel predecessors.
A series of news articles published in Nature evaluate recent shifts in interest and investment in jatropha and algae as biofuel feedstocks, as well as techniques to produce cellulosic ethanol and liquid fuel directly from biomass (content requires subscription or payment).
With the announcement this........ Read more »

People are no more fearful of crossing a street with a young male skinhead in it than they are a street with a smartly dressed woman present, unless, that is, a CCTV camera is overhead. The new finding appears to undermine one of the key justifications for Britain's network of 4.2 million surveillance cameras: that they provide reassurance to the public. It seems that the sight of a CCTV camera can have the opposite effect, cueing the perception of a threat. Dave Williams and Jobuda Ahmed presen........ Read more »

The idea that the kachina cult was not an indigenous development among the Pueblos but was instead introduced from the south seems to have originated with a 1974 article by Polly and Curtis Schaafsma. As they note, while some previous scholars had noted some elements of the cult that suggested Mesoamerican influence, the general consensus [...]... Read more »

There’s an old adage that pops up all the time not just in reference to conservation, but in the subject area of “you name it.” And for this very reason it has become quite ubiquitous.

A study out today in the journal Marine Ecology Progress Series shows that global warming could have a major effect on the fishing industry by forcing large fish populations from their original habitats. About half of the fish stocks studied in the Atlantic ocean, many of them commercially valuable species, have shifted northward over the [...]

One of my favorite cartoons as a child was "Speed Racer." It featured an all-American boy (first name, "Speed," last name, "Racer") engaging in that most American of pastimes: driving fast cars. Except that "Speed Racer" wasn't really American; it was made in Japan, and the original Japanese voices were crudely overdubbed in English. Perhaps I can be excused for not noticing the Japanese origins of the show -- I was only 10 years old. Even now, as an ........ Read more »

As I continue to catch up on my articles, this post is about an article by Rambold and colleagues that was published in the Journal of Neurochemistry. The researchers’ study was designed to identify compounds that would interfere with the propagation of the pathologic prion protein. The two compounds investigated in the present article were the main components of green tea, epigallocatechin gallate (EGCG) and gallocatechin gallate (GCG). This was an in vitro study that us........ Read more »

A new study on ecological restoration efforts in Minnesota illustrates the dangers of establishing native plant species using non-local sources.
For the last 30 years, organizations and landowners have been working to restore native vegetation to dunes at Park Point along the western shore of Lake Superior. At first glance, it might not seem like such a big deal that these projects have been planting American beachgrass in Minnesota using propagules from source populations in Michigan.

If there is a physical property in the world that provides useful information, chances are that at least some animals will have evolved a sensory system to exploit it. The Earth’s magnetic field is no exception: it provides useful and reliable information to navigate the globe. There has been extensive research into whether and how animals may use the magnetic field for navigation, and although most agree that it is being used, the nature of how this information is processed can still be a........

A supply chain as a virtual enterprise network. That is the underlying reasoning in the 2009 paper How to improve supply chain flexibility using strategic supply chain networks by Herwig Winkler.

Aging is associated with well described changing in sleep patterns.
Total sleep time decreases, elderly sleep less
It takes longer before falling a sleep
Elderly go to bed earlier and they awake earlier
There sleep architecture has changed, the slow wave sleep on EEG is reduced, REM sleep is reduced
They’re easier aroused from sleep
They sleep fragmented with many arousals

I happened across a nice little editorial that was published last year in the British Medical Journal that I am saddened to have not seen sooner. It is a piece written by a father of a 25-year-old who died of variant Creutzfeldt-Jakob disease (vCJD). In this short piece, he describes his experience of being involved in several advisory committees on the treatment of human prion diseases as a layperson. I would like to highlight a few of his comments. First, he was surprised to........ Read more »
