The North Carolina Museum of Natural Sciences hosts the final offering of its Charles Darwin Lecture Series on Tuesday, November 24 -- the 150th anniversary of Darwin's landmark publication of "The Origin of Species." Join Museum paleontologist and science historian Paul Brinkman for a free presentation titled "Charles Darwin's Beagle Voyage and the Origin of 'The Origin.'"
Dr. Brinkman completed his PhD in History of Science at the University of Minnesota with research in the history of 19th-century natural sciences, especially geology and paleontology. He has published a number of articles on Darwin, museum history, and...

In this study, we introduced two novel theoretical models, one based on neutral drift and the other assuming natural selection, by focusing on a common property of the distribution of mRNA abundance among a variety of eukaryotic cells, which reflects the result of long-term evolution. Our results demonstrated that (1) our models can reproduce two independently found phenomena simultaneously: the time development of gene expression divergence and Zipf's law of the transcriptome; (2) cytological constraints can be explicitly formulated to describe long-term evolution; (3) the model assuming that natural selection optimized r...

We present here the results of two trials run against free-flying Anopheles gambiae populations comparing the effects of two insect repellents (either DEET or KBR 3023, also known as icaridin) and an organophosphate insecticide at low-doses (pirimiphos-methyl, PM) used alone and in combination on bed nets. We showed that mixtures of PM and the repellents induced higher exophily, blood feeding inhibition and mortality among wild susceptible and resistant malaria vectors than compounds used alone. Nevertheless the synergistic interactions are only involved in the high mortality induced by the two mixtures. These field trials...

Dozens of researchers, clinicians, and ethicists sent a letter asking the NIH to fund research on medical ethics, conflicts of interest, and industry influence on prescribing behavior. Why? They note that stimulus funding has increased the NIH budget significantly, but the agency has “no mechanism for funding research on how commercial interests affect the choice of medical therapeutics.”
In their Nov. 17 letter, they write NIH director Francis Collins that the “NIH funds a substantial portion of the generation and dissemination of evidence, but the uptake of that evidence and its translation into clinica...

Article-Level Metrics and the Evolution of Scientific Impact:
Formally published papers that have been through a traditional prepublication peer review process remain the most important means of communicating science today. Researchers depend on them to learn about the latest advances in their fields and to report their own findings. The intentions of traditional peer review are certainly noble: to ensure methodological integrity and to comment on potential significance of experimental studies through examination by a panel of objective, expert colleagues. In principle, this system enables science to move forward on the c...

Conclusions
The results of the study indicate that Norwegian physicians have a limited knowledge of the key aspects of EBM but a positive attitude towards the concept. They had limited experience in the practice of EBM and were rather indifferent to the impact of EBM on medical practice. For solving a patient problem, physicians would rather consult a colleague than searching evidence based resources such as the Cochrane Library.

The wastewater released from industry often contains high levels of toxic heavy metals, which can kill organisms, damage ecosystems, and accumulate in the foodchain. Electroplating, lead smelting, mining, and countless other processes produce enormous volumes of such wastewater.
In a perfect world, remediation would be powered by a renewable energy supply, there would be no solid waste to dispose of, and the heavy metal contaminants could be recycled back into the industrial process with minimal losses. That would be industrial Utopia, of course, but something close might exist if scientists can genetically modify aquatic ...

In this study, by using a transgenic rat expressing ChR2 specifically in the RGCs under the regulation of a Thy-1.2 promoter, we tested the possibility that direct photoactivation of RGCs could restore effective vision. Although the contrast sensitivities of the optomotor responses of transgenic rats were similar to those observed in the wild-type rats, they were enhanced for visual stimuli of low-spatial frequency after the degeneration of native photoreceptors. This result suggests that the visual signals derived from the ChR2-expressing RGCs were reinterpreted by the brain to form behavior-related vision.

The creative editors or Spontaneous Generations: A Journal for the History and Philosophy of Science (see earlier mention here) are planning a focused discussion section on scientific instruments in a forthcoming issue of the journal.
With the “practical turn” in history and philosophy of science came a renewed interest in scientific instruments. Although they have become a nexus for worries about empiricism and standards of evidence, instruments only rarely feature as primary sources for scholars in the history and philosophy of science. Even historians of technology have been accused of underutilizing the evidence em...

This year, roughly 66,000 people will be diagnosed with non-Hodgkin lymphoma, while another 22,000 will be diagnosed with cancers of the brain. In parallel, our pet dogs also suffer from a range of similar spontaneous cancers. For thousands of years, humans and dogs have shared a unique bond--breathing the same air, drinking the same water, and living in the same environment. During the 21st century this relationship is now strengthene...

Mandatory Disclosure of Pharmaceutical Industry-Funded Events for Health Professionals:
We are in a period of unprecedented scrutiny of the relationships between the pharmaceutical industry and doctors [1]-[4]. Legislators are now considering how they might become involved in the regulation of these practices. This is a telling comment on the perceived failure of the medical profession to regulate itself and of self-regulation by industry. But r...

Laura Bonetta wrote an excellent article for the science journal Cell recently in which she quoted various science types who use Twitter on the subject of whether or not scientists should be tweeting. It’s a topic I’ve discussed more generally regarding scientists’ use of social media and online networking communities.
Anyway, she asked my opinion on a few matters regarding twitter and quoted me at some length. But, as is the way with such articles, which I’ve experienced from all three angles now, as interviewer, interviewee, and editor, she trimmed off the fat and rind from my responses, so I aske...

UPDATE – NOV 5: Still working through the almost 650 members of the list, but now up to the P’s.
Pressure was on from lots of science tweeps for to categorise my scientwist list…so I’ve made a start.
The spillover (lots of tweeps in the T to Z group from the TweepML.org version of my scientwist list have now each been given a category as I cannot squeeze them into the 500 limit for the main scientwist list.
Everyone else will get a second list assignment where appropriate as follows:
bio – med, health, psy, bioinformatics, pharma

Okay. Okay. Pressure was on to categorise my scientwist list…so I’ve made a start.
First off, the spillover (lots of tweeps in the T to Z group from the TweepML.org version of my scientwist list, which has 650 members or thereabouts) have now each been given a category as I cannot squeeze them into the 500 limit for the main scientwist list.
Everyone else from 0 to A to S are currently getting a second listing where appropriate as follows:
bio – including med, health, psy, bioinformatics, pharma
chem – all chemical sciences
earth – geo, environment, climate, oceans
physics – physics and...
