NASA scientist offers perspective on the factors that may lead to life on a planet(Phys.org)—NASA space scientist Pamela Conrad has offered a Perspective piece in the journal Science, reminding readers that the search for life on planets such as Mars, isn't limited to just looking for water. Instead, she notes, most researchers believe that a combination of events must occur, likely simultaneously for life to get a start and then to be maintained. | |
Cosmic impacts might help synthesize organic compoundsBullets of ice shot at high speeds can deposit organic compounds on surfaces they strike. The new findings suggest that comets might, indeed, have helped deliver key ingredients of life to Earth and perhaps elsewhere, researchers say. | |
Two spiral galaxies in the process of mergingAt this time of year, there are lots of gatherings often decorated with festive lights. When galaxies get together, there is the chance of a spectacular light show as is the case with NGC 2207 and IC 2163 | |
Magnetic fields on solar-type starsThe Sun rotates slowly, about once every 24 days at its equator although the hot gas at every latitude rotates at a slightly different rate. Rotation helps to drive the mechanisms that power stellar magnetic fields, and in slowly rotating solar-type stars also helps to explain the solar activity cycle. In the case of solar-type stars that rotate much faster than does the modern-day Sun, the dynamo appears to be generated by fundamentally different mechanisms that, along with many details of solar magnetic field generation, are not well understood. Astronomers trying to understand dynamos across a range of solar-type stars (and how they evolve) have been observing a variety of active stars, both slow and fast rotators, to probe how various physical parameters of stars enhance or inhibit dynamo processes. | |
Comet 67P/Churyumov-Gerasimenko in living colorRosetta's OSIRIS team have produced a color image of Comet 67P/Churyumov-Gerasimenko as it would be seen by the human eye. As anticipated, the comet turns out to be very grey indeed, with only slight, subtle colour variations seen across its surface. | |

How to take photos of Earth while whizzing past at 17,000 MPHWhen you're flying above Earth in a spaceship or space station, taking a clear picture below is more than a point-and-shoot job. As NASA astronaut Don Pettit explains in this video, you need to account for the motion of your little craft to get the best pictures below. And Pettit should know, being a photographer who captured many stunning timelapses in space. | |
Building a worldwide genetic library BRIC-by-BRICA house is only as good as its foundation. Built solid and strong, the resulting structure should last for decades.

Novel computational modeling, GI tract microorganismsDr. Arul Jayaraman, professor of chemical engineering at Texas A&M University and holder of the Ray B. Nesbitt Professorship, has collaborated with researchers from Tufts University School of Engineering in the computational evaluation of gastrointestinal (GI) tract microorganism function. The journal Nature Communications published the findings in a November 20 edition. | |
Researchers tame the inflammatory response in kidney dialysisFrequent kidney dialysis is essential for the approximately 350,000 end-stage renal disease (ESRD) patients in the United States. But it can also cause systemic inflammation, leading to complications such as cardiovascular disease and anemia, and patients who rely on the therapy have a five-year survival rate of only 35 percent. Such inflammation can be triggered when the complement cascade, part of the body's innate immune system, is inadvertently activated by modern polymer-based dialysis blood filters. New work by Penn researchers has found an effective way to avoid these problems by temporarily suppressing complement during dialysis. Their work appears online in Immunobiology ahead of print. | |

Still no alternative to the theory that Columbus brought syphilis across the AtlanticIn 1495 a horrific new disease appeared in Europe. Acquired by sexual contact and initially spread through Europe by mercenary soldiers from the army of King Charles VIII of France returning from a successful invasion of Italy, this new disease was extraordinarily unpleasant. Commentators at the time described dark green "boils that stood out like acorns," accompanied by a stench so vile that if you smelt it you would imagine yourself infected, and by pains so severe that it was "as if the sick had laid upon a fire". | |
Newly-identified gene mutation could help explain how breast cancer spreadsA newly-identified genetic mutation could increase our understanding of how breast cancer spreads and potentially guide treatment options for women with the disease, according to a study from Magee-Womens Research Institute (MWRI) and the University of Pittsburgh Cancer Institute (UPCI) presented today at the 2014 San Antonio Breast Cancer Symposium. | |

New, personalized online community helps patients live with dangerous heart rhythmMany people experience a slight quivering or racing heart at some point and usually give it little notice. But for those diagnosed with atrial fibrillation (AFib), that irregular heartbeat can be a serious condition that can increase the risk of stroke and needs medical attention. | |
ELECTRX has the nerve to envision revolutionary therapies for self-healingMany chronic inflammatory diseases and mental health conditions affecting military service members and veterans involve abnormal activity in the peripheral nervous system, which plays a key role in organ function. Monitoring and targeted regulation of peripheral nerve signals offer great promise to help patients restore and maintain their health without surgery or drugs. Current neuromodulation devices are typically used as a last resort, however, because they are relatively large (about the size of a deck of cards), require invasive surgical implantation and often produce side effects due to their lack of precision. DARPA's Electrical Prescriptions (ElectRx) program is seeking innovative research proposals to help transform neuromodulation therapies from last resort to first choice for a wide range of diseases. | |
Atypical development of language in children"I have always been fascinated by language," says Professor Nikki Botting.
