From Shakespeare to Star Trek and beyond: a Medline search for literary and,other allusions in biomedical titles -- BMJ [clip]

Thought this was a new perspective on the biomedical literature and a way of turning some light research and text searching into something interesting.

BMJ. 2005 Dec 24;331(7531):1540-2.     
>From Shakespeare to Star Trek and beyond: a Medline search for literary and other allusions in biomedical titles.
Goodman NW.
OBJECTIVES: To document biomedical paper titles containing literary and
other allusions. DESIGN: Retrospective survey. SETTING: Medline (1951 to
mid-2005) through Dialog Datastar. MAIN OUTCOME MEASURE: Allusions to
Shakespeare, Hans Christian Andersen, proverbs, the Bible, Lewis Carroll, and
movie titles, corrected and scaled for five year periods 1950-4 to 2000-4.
RESULTS: More than 1400 Shakespearean allusions exist, a third of them to
"What's in a name" and another third to Hamlet-mostly to "To be or not to be."
The trend of increasing use of allusive titles, identified from Shakespeare and
Andersen, is paralleled by allusions to Carroll and proverbs; the trend of
biblical allusions is also upward but is more erratic. Trends for newer
allusions are also upwards, including the previously surveyed "paradigm shift."
Allusive titles are likely to be to editorial or comment rather than to original
research. CONCLUSIONS: The similar trends are presumably a mark of a particular
learnt author behaviour. Newer allusions may be becoming more popular than older
ones. Allusive titles can be unhelpful to reviewers and researchers, and many
are now cliches. Whether they attract readers or citations is unknown, but
better ways of gaining attention exist.

Google Gene Project Comes into Question


BLUF: a novel FAD-binding domain involved in sensory transduction in microorganisms


UniProtKB/Swiss-Prot entry Q01371 [WC1_NEUCR] White collar 1 protein

May function as a transcription factor involved in light regulation. Binds and affects blue light regulation of the AL-3 gene. WC1 and WC2 proteins interact via homologous PAS domains, bind to promoters of light regulated genes such as FRQ, and activate transcription.

The LOV Domain Family: Photoresponsive Signaling Modules Coupled to Diverse Output Domains

Here, we review the properties of the light, oxygen, or voltage (LOV) family of blue-light photoreceptor domains, a subset of the Per-ARNT-Sim (PAS) superfamily. These flavin-binding domains, first identified in the higher-plant phototropins, are now shown to be present in plants, fungi, and bacteria. Notably, LOV domains are coupled to a wide array of other domains, including kinases, phosphodiesterases, F-box domains, STAS domains, and zinc fingers, which suggests that the absorption of blue light by LOV domains regulates the activity of these structurally and functionally diverse domains.

Bioinformatics on the Brink
Email: Kate Fodor - kfodor@the-scientist.com
The Scientist 2004, 18(24):34
Published         20 December 2004
When a working map of the human genome was announced in June 2000, it was immediately clear that it would open new avenues of study and transform the life sciences, both in academia and in industry. One of the many new opportunities was in bioinformatics: the use of computers to rapidly scan databases, analyze sequence data, and help predict protein structure based on DNA sequence. Companies and universities would be eager to purchase bioinformatics tools to help them manage the massive amounts of genomics and proteomics data they would be generating.
That has, indeed, turned out to be true. But for a number of reasons, the market opportunity for bioinformatics tools hasn't been as expansive as was thought, and many companies have suffered as a result.....
Despite the struggles that bioinformatics companies are experiencing, heavyweight, diversified IT companies such as IBM and Sun Microsystems show no signs of shying away from partnerships with the smaller companies or giving up on the bioinformatics market. "All the large IT vendors are getting very involved in life science," Zimmerman says. The big companies don't actually develop bioinformatics software, but they see opportunity in partnering with the software developers by providing hardware, service, and support for bioinformatics tools, and selling the complete package to firms involved in drug discovery.

Lowering Expectations at Science's Frontier
Jeon Kyung Woo/Newsis via Reuters
Published: January 15, 2006
THERE is considerable disorder in heaven when stem-cell scientists are chided by the Roman Catholic Church for the folly of pursuing "miracle cures." But such are the paradoxes generated by the implosion of a South Korean researcher's widely believed claims to have created human embryonic stem cells from patients.....The contrast between the fallibility of Dr. Hwang's claims and the general solidity of scientific knowledge arises from the existence of two kinds of science - a distinction that is often blurred when new advances are reported first by scientific journals and then by the news media. There is textbook science and frontier science, and the two types carry quite different expiration dates.
Textbook science is material that has stood the test of time and can be largely relied upon. It may include findings made just a few years ago, but which have been reasonably well confirmed by other laboratories. Science from the frontiers of knowledge, on the other hand, is wild, untamed and often either wrong or irrelevant to future research. A few years after they are published, most scientific papers are never cited again. Scientific journals try to impose order on the turbulent flow of new claims by having expert reviewers assess their merit. But even at the best journals, reviewers provide only a rough screen. Many papers slip through that later turn out to be innocently wrong. A few, like Dr. Hwang's, are found to be fraudulent....

BOOK REVIEWED - Robustness and Evolvability in Living Systems
by Andreas Wagner
When sitting on an aeroplane, we obviously hope that it won't crash. A tacit assumption behind this wish is that our biological system isn't about to crash either. It so happens that these systems share several features. Both have specific parts that serve certain functions. The plane was designed by engineers, who were in turn designed by evolution through natural selection. Both systems seem robust and yet fragile, but how can we reconcile these two seemingly opposing features? One answer is that they are robust and fragile to different perturbations, being particularly robust to perturbations that are common in their 'niche'. Another answer is that robustness can be in a trade-off with other features, such as price and reproduction rate...

Genetics. 2005 Aug;170(4):1501-13. Epub 2005 May 23.
Copy correction and concerted evolution in the conservation of yeast genes.
Pyne S, Skiena S, Futcher B.
The yeast Saccharomyces cerevisiae and other members of the genus Saccharomyces are descendants of an ancient whole-genome duplication event. Although most of the duplicate genes have since been deleted, many remain, and so there are many pairs of related genes. We have found that poorly expressed genes diverge rapidly from their paralog, while highly expressed genes diverge little, if at all. This lack of divergence of highly expressed paralogous gene pairs seems to involve gene correction: one member of the pair "corrects" the sequence of its twin, and so the gene pair evolves as a unit. This correction presumably involves gene conversion and could occur via a reverse-transcribed cDNA intermediate. Such correction events may also occur in other organisms. These results support the idea that copies of poorly expressed genes are preserved when they diverge to take on new functions, while copies of highly expressed genes are preserved when they are needed to provide additional gene product for the original function.

Michigan had distinguished itself, Levin had been informed: the state boasted two Davidson Fellows, and he had clearly been told these teenagers came trailing brainy superlatives. ''Genius loves company,'' announced the September press release about the students who had won scholarships awarded annually since 2001 by the Davidson Institute for Talent Development, a foundation that supports ''profoundly intelligent'' youths, a more recent term for off-the-charts children. ''Seventeen prodigies,'' the press release went on, were ''to be honored at the Library of Congress for contributions to society'' in the fields of science, math, technology, music and literature....

Trends Genet. 2005 Jan;21(1):21-5.
Microeconomic principles explain an optimal genome size in bacteria.
Ranea JA, Grant A, Thornton JM, Orengo CA

Bacteria can clearly enhance their survival by expanding their genetic
repertoire. However, the tight packing of the bacterial genome and the fact that
the most evolved species do not necessarily have the biggest genomes suggest
there are other evolutionary factors limiting their genome expansion. To clarify
these restrictions on size, we studied those protein families contributing most
significantly to bacterial-genome complexity. We found that all bacteria apply
the same basic and ancestral 'molecular technology' to optimize their
reproductive efficiency. The same microeconomics principles that define the
optimum size in a factory can also explain the existence of a statistical
optimum in bacterial genome size. This optimum is reached when the bacterial
genome obtains the maximum metabolic complexity (revenue )
for minimal regulatory genes (logistic cost).
