| Static killers? Relevance of Natural Killer cells Posted: 06 Sep 2013 06:58 AM PDT Mammals contain cells whose primary function is to kill other cells in the body. The so-called Natural Killer (NK) cells are highly important in defending our bodies against viruses or even cancer. Scientists at the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) provide evidence that NK cell activity can be influenced by phosphorylating a protein (STAT1) in NK cells. The results, which could be of immediate therapeutic relevance, are published in the journal Cell Reports.        |
| New Connection between Stacked Solar Cells Can Handle Energy of 70,000 Suns Posted: 06 Sep 2013 06:46 AM PDT North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar energy devices and reduce the cost of solar energy production. The new connections can allow these cells to operate at solar concentrations of 70,000 suns worth of energy without losing much voltage as “wasted energy” or heat.     |
| Space around others perceived just as our own Posted: 06 Sep 2013 06:38 AM PDT A study from Karolinska Institutet has shown that neurons in our brain 'mirror' the space near others, just as if this was the space near ourselves. The study, published in the scientific journal Current Biology, sheds new light on a question that has long preoccupied psychologists and neuroscientists regarding the way in which the brain represents other people and the events that happens to those people.     |
| The quasar and its Fata Morgana Posted: 06 Sep 2013 06:31 AM PDT Bonn astronomers discover how the image of a distant quasar splits into multiple images by the effects of a cloud of ionized gas in our own Milky Way Galaxy. Such events were predicted as early as in the 1970s, but the first evidence for one now has come from observations performed with the telescope array VLBA and analysed in the Max Planck Institute for Radio Astronomy.     |
| Molecular Marker Predicts Patients Most Likely to Benefit Longest From Two Popular Cancer Drugs Posted: 05 Sep 2013 10:02 AM PDT Johns Hopkins scientists have identified a molecular marker called “Mig 6” that appears to accurately predict longer survival -- up to two years -- among patients prescribed two of the most widely used drugs in a class of anticancer agents called EGFR inhibitors.     |
| Common virus is a new target for cancer treatment Posted: 05 Sep 2013 09:53 AM PDT Treatment for the common cytomegalovirus (CMV) has been shown to give seriously ill cancer patients a much improved prognosis. The treatment study was conducted on patients with malignant glioblastoma, but might also be effective in the future on a number of other forms of cancer. The study, which was led by scientists at Karolinska Institutet and Karolinska University Hospital, is now published in the scientific periodical The New England Journal of Medicine.     |
| Cheaper Chinese solar panels are not due to low-cost labour Posted: 05 Sep 2013 07:48 AM PDT A study of the photovoltaic industries in the US and China shows that China's dominance in solar panel manufacturing is not driven solely by cheaper labour and government support, but by larger-scale manufacturing and resulting supply-chain benefits.     |
