Billion-euro boost to EU science

By | July 20, 2010

European science is set for a serious shot in the arm, after the European Union's commissioner for research and innovation announced yesterday (19th July) that the EU will invest approximately €6.4 billion in research and development on the continent through 2011. Image: S. Solberg J. via WikimediaThe investment package, the largest ever infusion of funding into research activities across Europe, will create more than 165,000 jobs and help save struggling economies, said Ireland's M&aacut

iPSCs less pliable than ESCs?

By | July 19, 2010

Stem cells derived from adult tissues may be less able to differentiate into different tissues than those derived from embryos, because adult cells appear to retain an "epigenetic memory" of the cell type from which they were derived, according to two mouse studies published this week in Nature journals. An iPSC colonyImage: Jose M. Polo andKonrad HochedlingerThe papers show that induced pluripotent stem cells (iPSCs) "are not truly similar to [embryonic stem cells] when examined at a high reso

Video: Transcription, live

By | July 18, 2010

For the first time, scientists have devised a way to watch and analyze, in real time, the transcription of a single gene in a living human cell. Published online today (July 18) in Nature Methods, researchers at Bar-Ilan University in Israel describe their system to visualize and track the kinetics of transcription, including the speed and fluctuations of transcription of a single gene. Yaron Shav-Tal and colleagues at Bar-Ilan used their technique, which involves tagging the mRNA product from

Brain 'stars' help breathing

By | July 15, 2010

Cells originally believed to be no more than support for neurons have been getting a second-look lately, and a recent study suggests they may be critical to a fundamental bodily function: breathing. The finding, published online today (July 15) by linkurl:Science,;http://www.sciencemag.org/ further expands scientists' vague understanding how astrocytes -- glial cells in the brain named for their star-shape -- function in the brain, and offers a new way to investigate disorders associated with r

Longevity debate: Chips to blame?

By | July 14, 2010

At the heart of a feverish debate over the validity of a linkurl:recent genome-wide association study (GWAS) of centenarians;http://www.the-scientist.com/blog/display/57543/ is the authors' possible misuse of gene chips in different testing groups, part of an ongoing issue affecting other GWAS research. How this variation might impact the validity of the longevity findings, however, including the 150 SNPs associated with extreme longevity, is unclear. SNP chips are at the center of the longev

Q&A: How to study scientists

By | July 14, 2010

Scientists spend their time trying to uncover the most effective and efficient techniques and their impact on research, but what about the most effective and efficient scientists, and how they impact the field? linkurl:Pierre Azoulay;http://pazoulay.scripts.mit.edu/ of MIT's Sloan School of Management talked with The Scientist about his work on what influences the productivity of scientific researchers, and how productive scientists can, in turn, influence the scientific community.

#1 Gene for autoimmunity Rare genetic variants in the protein sialic acid acetylesterase (SASE) are linked to common human autoimmune diseases, including type 1 diabetes, arthritis, and Crohn's disease. In mice, defects in the protein have been linked to problems in B-cell signaling and the development of auto-antibodies. I. Surolia, et al., "Functionally defective germline variants of sialic acid acetylesterase in autoimmunity," Nature, 466:243-7. Epub 2010 Jun 16. linkurl:Eval;http://f1000b
