Self-destructive effects of magnetically-doped ferromagnetic topological insulators Posted: 19 Jan 2015 12:43 PM PST A new atomic-scale study of the surface properties of certain ferromagnetic topological insulators reveals that these materials exhibit extreme, unexpected, and self-destructive electronic disorder.

New laser for computer chips: International team of scientists constructs first germanium-tin semiconductor laser for silicon chips Posted: 19 Jan 2015 09:45 AM PST The first semiconductor consisting solely of elements of main group IV has been revealed by researchers. The germanium-tin (GeSn) laser can be applied directly onto a silicon chip and thus creates a new basis for transmitting data on computer chips via light: this transfer is faster than is possible with copper wires and requires only a fraction of the energy.

New high-speed 3-D microscope -- SCAPE -- gives deeper view of living things Posted: 19 Jan 2015 09:45 AM PST SCAPE, a new microscope that images living things in 3-D at very high speeds, has been developed by engineers. The microscope uses a simple, single-objective imaging geometry that requires no sample mounting or translation, making it possible to image freely moving living samples. Its ability to perform real-time 3-D imaging at cellular resolution in behaving organisms could be transformative for biomedical and neuroscience research, experts say.

Dawn spacecraft delivers new image of dwarf planet Ceres Posted: 19 Jan 2015 08:31 AM PST As NASA's Dawn spacecraft closes in on Ceres, new images show the dwarf planet at 27 pixels across, about three times better than the calibration images taken in early December. These are the first in a series of images that will be taken for navigation purposes during the approach to Ceres.

How planetary building blocks evolved from porous to hard objects Posted: 19 Jan 2015 06:09 AM PST Thinking small has enabled an international team of scientists to gain new insight into the evolution of planetary building blocks in the early solar system. Planetary scientists study chondritic meteorites to reconstruct planet formation. These meteorites are made of a mixture of solid chondrules, millimeter-sized beads (the approximate width of a penny) that became embedded in a fluffy matrix.

Extremely short, sharp flash of radio waves from unknown source in the universe, caught as it was happening Posted: 19 Jan 2015 05:32 AM PST A strange phenomenon has been observed by astronomers right as it was happening -- a 'fast radio burst'. The eruption is described as an extremely short, sharp flash of radio waves from an unknown source in the universe.

Geographic clusters of underimmunization identified in Northern California Posted: 19 Jan 2015 05:32 AM PST Researchers used spatial analysis software and electronic medical records to identify clusters of underimmunization and vaccine refusal among Kaiser Permanente members in Northern California, according to a study.

Optic fiber for recording the temperature in extreme industrial environments Posted: 19 Jan 2015 05:30 AM PST Optic fiber is normally used in the field of telecommunications to transmit information using light, but a group of researchers developed a technique that makes it possible to use optic fiber as a thermometer in extreme industrial environments.

Switchable adhesion principle enables damage-free handling of sensitive devices even in vacuum Posted: 19 Jan 2015 05:30 AM PST Researchers enhanced the Gecko adhesion principle such that adhesion can be switched on and off in vacuum.

New composite protects from corrosion from high mechanical stress Posted: 19 Jan 2015 05:30 AM PST A new composite material prevents metal corrosion in an environmentally friendly way, even under extreme conditions. It can be used wherever metals are exposed to severe weather conditions, aggressive gases, salt, heavy wear or high pressures.

President Lincoln’s cottage 3D laser-scanned by researchers Posted: 16 Jan 2015 01:14 PM PST A team of undergraduate students traveled to Washington to document President Lincoln's Cottage -- the only designated national monument in the District of Columbia -- using 3D laser scanning technology. Images collected from the scanning will support preservation research, potentially impacting historical interpretation and public outreach at the site, which was used by Lincoln and his family to escape the summer heat of downtown Washington.
