| In breast cancer metastasis, researchers identify possible drug target Posted: 27 Jan 2013 10:42 AM PST The spread of breast cancer to distant organs within the body, an event that often leads to death, appears in many cases to involve the loss of a key protein, according to researchers, whose new discoveries point to possible targets for therapy.  |
| Poor sleep in old age prevents the brain from storing memories Posted: 27 Jan 2013 10:42 AM PST The connection between poor sleep, memory loss and brain deterioration as we grow older has been elusive. But for the first time, scientists have found a link between these hallmark maladies of old age. Their discovery opens the door to boosting the quality of sleep in elderly people to improve memory.  |
| Cities affect temperatures for thousands of miles Posted: 27 Jan 2013 10:42 AM PST Even if you live more than 1,000 miles from the nearest large city, it could be affecting your weather. New research shows that the heat generated by everyday activities in metropolitan areas influences major atmospheric systems, raising and lowering temperatures over thousands of miles.  |
| Toward 2-D devices: Single-atom-thick patterns combine conductor and insulator Posted: 27 Jan 2013 10:42 AM PST Scientists have created a process to make patterns in atom-thick layers that combine a conductor -- graphene -- and an insulator -- hexagonal boron nitride. The process may lead to new possibilities for two-dimensional electronics.  |
| Demagnetization by rapid spin transport Posted: 27 Jan 2013 10:42 AM PST The fact that an ultrashort laser pulse is capable of demagnetizing a ferromagnetic layer in a jiffy has been well-known since approximately 1996. What we don't yet understand, however, is how exactly this demagnetization works. Now, physicists have shown that it turns out not to be the light pulse itself that prompts demagnetization.  |
| Accelerating neutral atoms on a table top Posted: 27 Jan 2013 10:42 AM PST Conventional as well as compact laser-based particle acceleration schemes hinge on accelerating electric fields and are therefore ineffective for neutral atoms, which do not respond to these fields. Researchers have now generated a table-top mega-electron-volt neutral atom source. The technique involves the stripping of eight electrons per Argon atom in a cluster, accelerate the ions and subsequently put back the electrons into the ions with 100 percent conversion efficiency.  |
| Patients' own skin cells are transformed into heart cells to create 'disease in a dish' Posted: 27 Jan 2013 10:42 AM PST Researchers have unveiled the first maturation-based "disease in a dish" model for arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C). The model was created using induced pluripotent stem cells and a new method to mimic metabolic maturity. This model is likely more relevant to human ARVD/C than other models and therefore better suited for studying the disease and testing new treatments.  |
| NASA's Tracking and Data Relay Satellite System offers upgrade to vital communications net Posted: 27 Jan 2013 07:28 AM PST NASA's Tracking and Data Relay Satellite System, also known as the Space Network, will get an upgrade this month when the agency launches the first of a new generation of communications satellites to connect man of NASA's spacecraft to their control centers and mission data centers.  |
| Organizing human specimen collections: Getting the best out of biobanks Posted: 25 Jan 2013 07:42 AM PST The diversity of biobanks, collections of human specimens from a variety of sources, raises questions about the best way to manage and govern them, finds a new study. The research highlights difficulties in standardizing these collections and how to make these samples available for research.  |
| Fantasy sports users spend more time in front of television on gamedays Posted: 25 Jan 2013 07:39 AM PST As the weekend approaches, you may notice your household's fantasy sports user paying more attention to the television, according to a new study.  |
