| Titan glowing at dusk and dawn Posted: 22 Oct 2014 02:01 PM PDT New maps of Saturn's moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one.       |
| Thermal paper cash register receipts account for high bisphenol A (BPA) levels in humans Posted: 22 Oct 2014 11:36 AM PDT BPA from thermal paper used in cash register receipts accounts for high levels of BPA in humans. Subjects studied showed a rapid increase of BPA in their blood after using a skin care product and then touching a store receipt with BPA.  |
| Highly effective new anti-cancer drug shows few side effects in mice Posted: 22 Oct 2014 11:35 AM PDT A new drug, OTS964, can eradicate aggressive human lung cancers transplanted into mice, scientists report. It inhibits the action of a protein that is overproduced by several tumor types but is rarely expressed in healthy adult tissues. Without it, cancer cells fail to complete the cell-division process and die.  |
| As permafrost soils thaw soil microbes amplify global climate change Posted: 22 Oct 2014 10:14 AM PDT Scientists have discovered how an invisible menagerie of microbes in permafrost soils acts as global drivers of Earth processes such as climate via gas exchange between soils and the atmosphere. These findings will help climate modelers more accurately predict Earth's future climate.  |
| Posted: 22 Oct 2014 10:06 AM PDT The HARPS instrument at ESO's La Silla Observatory in Chile has been used to make the most complete census of comets around another star ever created. Astronomers have studied nearly 500 individual comets orbiting the star Beta Pictoris and has discovered that they belong to two distinct families of exocomets: old exocomets that have made multiple passages near the star, and younger exocomets that probably came from the recent breakup of one or more larger objects.  |
| Mathematical model shows how brain remains stable during learning Posted: 22 Oct 2014 09:30 AM PDT Complex biochemical signals that coordinate fast and slow changes in neuronal networks keep the brain in balance during learning, according to an international team of scientists. Neuronal networks form a learning machine that allows the brain to extract and store new information from its surroundings via the senses. Researchers have long puzzled over how the brain achieves sensitivity and stability to unexpected new experiences during learning -- two seemingly contradictory requirements.  |
| Human skin cells reprogrammed directly into brain cells Posted: 22 Oct 2014 09:30 AM PDT Scientists have described a way to convert human skin cells directly into a specific type of brain cell affected by Huntington's disease, an ultimately fatal neurodegenerative disorder. Unlike other techniques that turn one cell type into another, this new process does not pass through a stem cell phase, avoiding the production of multiple cell types, report researchers.  |
