Boldly illuminating biology’s ‘dark matter’July 16, 2013 [image: phylogenetic_inference] The phylogenetic trees are based on up to 38 marker genes and sequences are collapsed at the phylum level occluding subgroups such as the Geoarchaeota which clusters within the Crenarchaeota. Phyla containing SAGs from this study are highlighted in red. Superphyla (TACK, DPANN, Terrabacteria, FCB, PVC and Patescibacteria) are highlighted with colour ranges. The phylogenetic robustness (monophyly score) of phyla and superphyla is indicated by a small circle on the node: black circle (node was resol... mais »

New theory uncovers cancer’s deep evolutionary roots Authors predict that if cancer cells are saturated with oxygen but deprived of sugar, it will slow them down or even even kill them July 16, 2013 This typical four-week-old human embryo looks similar to fish embryos, with proto-gills and a tail.(credit: University of New South Wales) A new way to look at cancer — by tracing its deep evolutionary roots to the dawn of multicellularity more than a billion years ago — has been proposed by Paul Davies of Arizona State University’s Beyond Center for Fundamental Concepts in Science in colla... mais »

New mode of cellular communication discovered in the brain Glial cells provide protective proteins and genetic information to neurons July 18, 2013 Exosomes (“exosomen” in German) are small vesicles that contain proteins and nucleic acids. They are commonly present in close proximity to nerve cell axons, where they are ideally positioned to supply protective substances. Scale bar: 50 microns. (Credit: Institute of Molecular Cell Biology) Johannes Gutenberg University Mainz (JGU) researchers have discovered a new form of communication between neurons and neighboring of a specific type o... mais »

‘Intelligent knife’ tells surgeon if tissue is cancerous in 3 secondsJuly 19, 2013 [image: intelligent_knife] (Credit: Imperial College London) Scientists have developed an “intelligent knife” (iKnife) that can tell surgeons immediately whether the tissue they are cutting is cancerous or not. In the first study to test the iKnife invention (based on “rapid evaporative ionization mass spectrometry (REIMS)) in the operating theater, iKnife diagnosed tissue samples from 91 patients with 100 per cent accuracy. It instantly (within 3 seconds) provided information that normally takes up to ... mais »

Dennis Normile A clinical trial led by cardiologist Hiroaki Matsubara of Kyoto Prefectural University of Medicine indicated that the blockbuster hypertension drug valsartan lowers the risk of stroke and angina for some patients. A university investigation, however, concluded that data had been manipulated; after reanalysis, the reduced risk of stroke and angina disappeared. The paper was retracted and Matsubara resigned from the... mais »

Let’s Spend Some Time Apart: Long Distance Relationships Are Deeper A study takes a closer look at why absence makes the heart grow fonder. By Belinda Luscombe @youselessJuly 18, 2013 [image: BA10266]Absence, according to the latest research, does make the heart grow fonder — as long as there’s videochat, IMing, telephones or texting. About three million spouses in the U.S. live far each away from each other, even though they’d prefer to live together, and the new study, published in the *Journal of Communication*, found that the separation did not have such a negative effect on their ... mais »

Promising Alzheimer's 'drug' halts memory loss posted by news on june 26, 2013 - 9:30pm CHICAGO --- A new class of experimental drug-like small molecules is showing great promise in targeting a brain enzyme to prevent early memory loss in Alzheimer's disease, according to Northwestern Medicine® research. Developed in the laboratory of D. Martin Watterson, the molecules halted memory loss and fixed damaged communication among brain cells in a mouse model of Alzheimer's. "This is the starting point for the development of a new class of drugs," said Watterson, lead author of a paper on ... mais »
