Surprising material could play huge role in saving energy: Tin selenide is best at converting waste heat to electricity

Surprising material could play huge role in saving energy: Tin selenide is best at converting waste heat to electricity | Science technology and reaserch | Scoop.it
One strategy for addressing the world's energy crisis is to stop wasting so much energy when producing and using it, such as in coal-fired power plants or transportation. Nearly two-thirds of energy input is lost as waste heat. Now scientists have discovered a surprising material that is the best in the world at converting waste heat to useful electricity. This outstanding property could be exploited in solid-state thermoelectric devices, with potentially enormous energy savings.

Nanostructures with applications in infrared and terahertz ranges

Nanostructures with applications in infrared and terahertz ranges | Science technology and reaserch | Scoop.it
Scientists have created a compound semiconductor of nearly perfect quality with embedded nanostructures containing ordered lines of atoms that can manipulate light energy in the mid-infrared range. More efficient solar cells, less risky and higher resolution biological imaging, and the ability to transmit massive amounts of data at higher speeds are only a few applications that this unique semiconductor will be able to support.

Knowledge transfer between computers: Computers teach each other Pac-Man

Knowledge transfer between computers: Computers teach each other Pac-Man | Science technology and reaserch | Scoop.it
Researchers have developed a method to allow a computer to give advice and teach skills to another computer in a way that mimics how a real teacher and student might interact. Researchers had the agents -- as the virtual robots are called -- act like true student and teacher pairs: student agents struggled to learn Pac-Man and a version of the StarCraft video game. The researchers were able to show that the student agent learned the games and, in fact, surpassed the teacher.

How light affects our brain's performance: Photic memory for executive brain responses

How light affects our brain's performance: Photic memory for executive brain responses | Science technology and reaserch | Scoop.it
It has long been known that light exerts powerful effects on the brain and on our well-being. Light is not only required for vision but is also essential for a wide range of “non-visual” functions including synchronization of our biological clock to the 24h day-night cycle. A novel photoreceptor has now been shown to be an essential component for relaying light information to a set of so-called non-visual centers in the brain. Continuous changes in light throughout the day also change us, new research suggests.

Biostatistics approach to genetics yields new clues to roots of autism

Biostatistics approach to genetics yields new clues to roots of autism | Science technology and reaserch | Scoop.it
Researchers have developed a statistical method for genetic screens that improves the classic genome-wide association screen, and, applying to autism, have uncovered genes related to the disorder that had not been suggested in previous analyses. The scientists offer evidence that beginning treatment in infants at the first symptoms could change the course of the disease, possibly preventing the permanent “pruning” of neurons, which occurs during the first two years of life, from cementing autistic symptoms in place.

Your memory is no video camera: It edits the past with present experiences | Science technology and reaserch | Scoop.it
Your memory is a wily time traveler, plucking fragments of the present and inserting them into the past, reports a new study. In terms of accuracy, it's no video camera. Rather, memory rewrites the past with current information, updating your recollections with new experiences to aid survival. Love at first sight, for example, is more likely a trick of your memory than a Hollywood-worthy moment.

Fabricating nanostructures with silk could make clean rooms green rooms | Science technology and reaserch | Scoop.it
Engineers have demonstrated that it is possible to generate nanostructures from silk in an environmentally friendly process that uses water as a developing agent and standard fabrication techniques. This approach provides a green alternative to the toxic materials commonly used in nanofabrication while delivering fabrication quality comparable to conventional synthetic polymers. Nanofabrication is at the heart of manufacture of semi-conductors and other electronic and photonic devices.

Overcoming structural uncertainty in computer models

Overcoming structural uncertainty in computer models | Science technology and reaserch | Scoop.it
A computer model is a representation of the functional relationship between one set of parameters, which forms the model input, and a corresponding set of target parameters, which forms the model output. A true model for a particular problem can rarely be defined with certainty. The most we can do to mitigate error is to quantify the uncertainty in the model. Scientists have now offered a method to incorporate judgments into a model about structural uncertainty that results from building an 'incorrect' model.
