RNA interference (RNAi) is an important process used by many different organisms to regulate the activity of genes. The animation takes you on an audio-visual journey through the steps of gene expression and... mais »
Nanotechnology
*A nanowire endoscope for imaging inside a single cell* December 22, 2011 [image: Endoscope Sensing] An endoscope that can provide high-resolution optical images of the interior of a single living cell, or precisely deliver genes, proteins, therapeutic drugs or other cargo without injuring or damaging the cell, has been developed by researchers from Berkeley Lab and the University of California (UC) Berkeley. The researchers attached a tin-oxide nanowire waveguide to the tapered end of … more… Reconfigurable silicon nanowire transistors December 22, 2011 [image: Universal transistor]... mais »
Memory
*Neuroscientists identify a master controller of memory* December 23, 2011 When you experience a new event, your brain encodes a memory of it by altering the connections between neurons. This requires turning on many genes in those neurons. Now, neuroscientists at MIT’s McGovern Institute for Brain Research have identified what may be a master gene that controls this complex process. The findings reveal some of … more…
Galaxy at dawn of time
* NASA telescopes help find rare galaxy at dawn of time* December 23, 2011 [image: Distant galaxy] Astronomers using NASA’s Spitzer and Hubble space telescopes have discovered that one of the most distant galaxies known is churning out stars at a shockingly high rate. The blob-shaped galaxy, called GN-108036, is the brightest galaxy found to date at such great distances. The galaxy, which was discovered and confirmed using ground-based telescopes, is 12.9 … more…
Google to Reach Consumers
Using Google’s Data to Reach Consumers By ANDREW ADAM NEWMAN Published: December 22, 2011 THE viruses that Google researchers usually focus on are those that strike computers, but in recent years, they have studied those that infect people, too.

CLINICAL PRACTICE The Chronic Fatigue Retraction: Good Science Takes Time It was a long time coming: a journal retracts a controversial 2009 paper linking a virus to chronic fatigue. The good news? Faulty data can't hide. By ALICE PARK | @aliceparkny | December 22, 2011 [image: fatigue] It’s been a tough week for the editors of the venerable journal *Science*. First came the controversy surrounding their decision, at the request of government security officials, to omit key details in a paper describing how researchers had managed to create an aerosolized form of the deadly H5N1 bird ... mais »

Seu objetivo principal é fornecer informações georreferenciadas e espacializadas sobre a realidade gaúcha, estabelecendo comparações entre os municípios, os demais estados brasileiros e alguns países selecionados, colaborando desta forma, para a formulação das políticas públicas.
Parkinson's Disease
Potential Biomarker for Parkinson's Disease Identified Megan Brooks Authors and Disclosures December 21, 2011 — Phosphorylated alpha-synuclein, which may be detected in blood plasma, shows promise as a diagnostic biomarker for Parkinson's disease (PD), researchers report in the December issue of the *Journal of the Federation of American Societies for Experimental Biology* (the *FASEB Journal*). Alpha-synuclein is believed to play a "pivotal role" role in the development of the synucleinopathies, PD, and dementia with Lewy bodies (DLB), Penelope G. Foulds, PhD, from the University of...mais »
Alzheimer's Disease
Blood Signature May Predict Alzheimer's Disease Deborah Brauser Authors and Disclosures December 21, 2011 — A molecular signature found in serum samples may predict future development of Alzheimer's disease (AD), even before the first symptoms of the disease occur in patients, new research suggests. In a cohort study of more than 100 elderly patients with mild cognitive impairment (MCI), investigators found that those who progressed to AD less than 4 years later had a molecular signature suggesting a state of increased hypoxia. "The study is important, as it identifies molecular chang...mais »
