| Flowing against the stream: Inanimate beads behave in lifelike ways Posted: 01 May 2015 12:16 PM PDT Synthetic microscopic beads sense changes in their environment and self-propel to migrate upstream, a step toward the realization of biomimetic microsystems with the ability to sense and respond to environmental changes.  |
| Long-term galactic cosmic ray exposure leads to dementia-like cognitive impairments Posted: 01 May 2015 12:16 PM PDT What happens to an astronaut's brain during a mission to Mars? Nothing good. It's besieged by destructive particles that can forever impair cognition, according to a radiation oncology study. Exposure to highly energetic charged particles -- much like those found in the galactic cosmic rays that bombard astronauts during extended spaceflights -- cause significant damage to the central nervous system, resulting in cognitive impairments.  |
| The language of invention: Most innovations are rephrasings of past inventions Posted: 01 May 2015 09:54 AM PDT Most new patents are combinations of existing ideas and pretty much always have been, even as the stream of fundamentally new core technologies has slowed, according to a new study.  |
| NASA Completes MESSENGER Mission with Expected Impact on Mercury's Surface Posted: 01 May 2015 08:34 AM PDT A NASA planetary exploration mission came to a planned, but nonetheless dramatic, end April 30 when it slammed into Mercury's surface at about 8,750 mph and created a new crater on the planet's surface.  |
| Pulsar with widest orbit ever detected Posted: 01 May 2015 08:15 AM PDT A team of highly determined high school students discovered a never-before-seen pulsar. Further observations by astronomers using the GBT revealed that this pulsar has the widest orbit of any around a neutron star and is part of only a handful of double neutron star systems.  |
| New exoplanet too big for its star challenges ideas about how planets form Posted: 01 May 2015 06:59 AM PDT The discovery of a strange exoplanet orbiting very close to a small cool star 500 light years away is challenging ideas about how planets form.  |
| Twenty exoplanets are now available for naming proposals Posted: 01 May 2015 06:58 AM PDT The 20 most popular exoplanets have been made available for naming proposals from registered clubs and non-profit organizations.  |
| Social factors may not be necessary to produce or explain conformity Posted: 30 Apr 2015 05:23 AM PDT Behavioral conformity has been studied extensively and is commonly explained in terms of social pressure or impact. Surprisingly, however, recent research suggests that social factors may not be necessary to produce or explain conformity. According to their study people may simply confuse memories of their own behavior with memories of the behavior of others, and then reproduce mental "averages" thereof.  |
| Human brain inspires computer memory Posted: 28 Apr 2015 05:17 AM PDT How is it possible to create computer memory that is both faster and consumes less energy? Researchers have unlocked the physical mechanisms involved in new-generation magnetic memory, and have shown that these mechanisms could be used as "synapses" in a new type of neuro-inspired system, able to learn how to store and retrieve information.  |
