A Most Lively Virus

by Merry Youle in Small Things Considered

Morphologically speaking, the viruses of mesophilic and moderately thermophilic bacteria and archaea are a dull bunch. Of 5,100 surveyed, 97% are ho-hum head-and-tail phages—icosahedral heads with helical tails. The remainder were tailless icosahedra or filaments, except for two spindle-shaped oddballs. If you'd like more structural excitement, best to go virus hunting in geothermally-heated aquatic environments above 80 ºC—the hot springs, mud holes, and deep-sea hydrothermal vents—and b........

But is it grammar?

by Mark D. in The Ideophone

Finally, some commentaries on Evans & Levinson 2009 — a recent BBS paper that argues for linguistic diversity and against Universal Grammar— are trickling down the blogosphere. Nigel Duffield's "Roll up for the mystery tour" argues that "Universal Grammar ... walks free from the courtroom", based on the crucial point that "facts about attained, endstate grammars bear only tangentially on theories of UG". Which leads me to wonder: is it grammar?... Read more »

Use of Multiple Proteases for Improved Protein Digestion

by gkobs in Promega Connections

One of the approaches to identify proteins by mass spectrometry includes the separation of proteins by gel electrophoresis or liquid chromatography. Subsequently the proteins are cleaved with sequence-specific endoproteases. Following digestion the generated peptides are investigated by determination of molecular masses or specific sequence. For protein identification the experimentally obtained masses/sequences are compared with theoretical [...]... Read more »

The many lives of an inverted genomic region

by Razib Khan in Gene Expression

About five years ago Kari Stefansson published an interesting paper, A common inversion under selection in Europeans. The basic thrust of the results was that a particular genomic region in Europeans exhibited a pattern of variation whereby there was one variant which was inverted in relation to the modal type. They labelled them “H2″ and [...]... Read more »

Do you remember the sheer terror you felt, when you first started your medical school clinical rotations? Your first two years were probably spent in classrooms and small-group labs discussing anatomy, pharmacology, pathology, etc.Then BAM! You are thrown into the deep end of the pool. You are now on a clinical team of medical professionals taking care of actual patients!Some students fare better than others during this abrupt transition period.

You either believe in it all, or you don’t

by Tom Rees in Epiphenom

Many people believe in fate. When bad or good things happen, they tend to think they happened for a reason – even for events that are entirely random (winning the lottery, for instance). Often, people think that these things happen because some guiding hand or supernatural force caused them.So the question is, why are these delusions so common? Do we humans have an inbuilt predisposition (a cognitive bias) that leads us to anthropomorphize events? That’s one explanation that’s been suggest........ Read more »

Ecosystem services from agriculture

by Paul Spraycar in Beyond Climate Change

The agricultural sector stands to benefit from the use of markets to create value for the non-commodity benefits they provide to society. Researchers writing in Ecological Economics identify specific actions to be taken to shape the form and function of markets for ecosystem services provided by agriculture.To facilitate effective interactions between buyers and sellers, market actors must address issues of regulation, market design, program coordination (e.g., with other incentives for providin........

Models on how to integrate health service and research varies from country to country.

Opportunity costs of overharvesting tuna

by Paul Spraycar in Beyond Climate Change

A major opportunity – worth $3 billion over the next half century – in the Western and Central Pacific Ocean may be lost by the tuna fishing industry, which risks declining profits in the face of declining tuna stocks.Capturing this additional economic value would more than double the industry’s profits by mid-century, according to a projection published in this month’s Conservation Letters: 'Bioeconomic losses from overharvesting tuna.' The authors developed a ........ Read more »
