| Tool for nonstatisticians automatically generates models that glean insights from complex datasets Posted: 15 Jan 2019 02:43 PM PST Researchers are hoping to advance the democratization of data science with a new tool for nonstatisticians that automatically generates models for analyzing raw data. |
| Breakthrough in ice-repelling materials Posted: 15 Jan 2019 01:23 PM PST Icy weather is blamed for multibillion dollar losses every year in the United States, including delays and damage related to air travel, infrastructure and power generation and transmission facilities. Now researchers have reported creating a durable silicone polymer coating capable of repelling ice from any surface. |
| Pore size influences nature of complex nanostructures Posted: 15 Jan 2019 01:23 PM PST In new research that could help inform development of new materials, chemists have found that the empty space ('pores') present in two-dimensional molecular building blocks fundamentally changes the strength of these van der Waals forces, and can potentially alter the assembly of sophisticated nanostructures. |
| New evidence of superconductivity at near room temperature Posted: 15 Jan 2019 01:23 PM PST Researchers have taken a major step toward reaching one of the most sought-after goals in physics: room temperature superconductivity. |
| Einstein-de Haas effect has a central role in ultrafast demagnetization processes Posted: 15 Jan 2019 01:23 PM PST The Einstein-de Haas effect, first demonstrated more than a century ago, provides an intriguing link between magnetization and rotation in ferromagnetic materials. Researchers have now found that the effect has also a central role in ultrafast processes that happen at the sub-picosecond timescale -- and thus deliver fresh insight into materials that might form the basis for novel devices. |
| Brilliant glow of paint-on semiconductors comes from ornate quantum physics Posted: 15 Jan 2019 11:41 AM PST A new wave of semiconductors that can be painted on is on the horizon. It bears the promise of revolutionizing lighting all over again and of transforming solar energy. Ornate quantum particle action, revealed here, that drives the new material's properties defies the workings of established semiconductors. |
| Engineers 3D print smart objects with 'embodied logic' Posted: 15 Jan 2019 11:41 AM PST Using stimuli-responsive materials and geometric principles, engineers have designed structures that have 'embodied logic.' Through their physical and chemical makeup alone, they are able to determine which of multiple possible responses to make in response to their environment. |
| New effect in the interaction of plasmas with solids discovered Posted: 15 Jan 2019 10:28 AM PST If a plasma comes in contact with a solid, under certain circumstances the surface is changed fundamentally and permanently. Researchers have now discovered a surprising effect, in which the electronic properties of the solid material, such as its electrical conductivity, can be changed in a controlled, extremely fast and reversible manner, by ion impact. |
| Power stations driven by light Posted: 15 Jan 2019 10:28 AM PST The smallest building blocks within the power stations of organisms which get their energy directly from the sun are basically miniature reactors surrounded by collectors which capture photons and forward them to the center. The close correlation between structure and interaction of the components boosts productivity, a strategy which researchers are using for increasing the efficiency of solar technology. |
| Mathematical model can improve our knowledge on cancer Posted: 15 Jan 2019 09:44 AM PST Researchers have developed a new mathematical tool, which can improve our understanding of what happens when cells lose their polarity (direction) in diseases such as cancer. The result is advancing our understanding of how the fertilized egg cell develops into a complete organism. Biological shapes, like individual organs or an entire body, can be reproduced or maintained with great accuracy, just like in the embryonic development or during the adult stage. |
| Keeping roads in good shape reduces greenhouse gas emissions Posted: 15 Jan 2019 09:44 AM PST Keeping road pavement in good shape saves money and energy and reduces greenhouse gas emissions, more than offsetting pollution generated during road construction, according to a new study. |
| Light up logic: Engineers perform computational logic with light Posted: 15 Jan 2019 09:11 AM PST For the first time, researchers performed logic operations -- the basis of computation -- with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods used open up research possibilities including low-power, high-performance computer chips. |
| Multimaterial 3D printing used to develop fast response stiffness-tunable soft actuator Posted: 15 Jan 2019 09:11 AM PST Researchers have designed and fabricated a fast-response, stiffness tunable (FRST) soft actuator which is able to complete a softening-stiffening cycle within 32 seconds. |
| Bike share programs show infrequent helmet use, little disparity among neighborhoods Posted: 15 Jan 2019 09:11 AM PST People riding free-floating bike share rentals in Seattle are wearing helmets infrequently, according to a new analysis. Only 20 percent of bike share riders wore helmets in the study, while more than 90 percent of cyclists wore helmets while riding their own bikes. Different research on the free-floating bike share systems showed that bikes were usually available in all Seattle neighborhoods across economic, racial and ethnic lines. However, more bikes were located in more-advantaged neighborhoods. |
| Dissidents under authoritarian rule: Staying anonymous yet trustworthy Posted: 15 Jan 2019 09:11 AM PST Minority and dissident communities face a perplexing challenge in countries with authoritarian governments. They need to remain anonymous to avoid persecution, but also must establish a trustworthy identity in their communications. An interdisciplinary group of researchers has designed an application to meet both of these requirements. |
| Serious problems with forensic software Posted: 15 Jan 2019 08:19 AM PST New research finds significant flaws in recently released forensic software designed to assess the age of individuals based on their skeletal remains. The researchers report that, on average, the software's age estimates are off by more than 14 years. |
| Animals may get used to drones Posted: 15 Jan 2019 08:19 AM PST A new study shows that over time, bears get used to drones. Previous work indicated that animals behave fearfully or show a stress response near drone flights. Using heart monitors to gauge stress, however, researchers here found that bears habituated to drones over a 3 to 4-week period and remained habituated. |
| Sugary stent eases suturing of blood vessels Posted: 15 Jan 2019 08:19 AM PST A team has concocted a sugar-heavy stent to reduce the margin of error in a delicate surgical procedure. |
| Understanding physics could lead to big gains in shale oil recovery Posted: 15 Jan 2019 08:19 AM PST Oil companies are missing out on vast sums of recoverable oil in unconventional reservoirs, according to experts. |
| Experiments detect entropy production in mesoscopic quantum systems Posted: 15 Jan 2019 08:19 AM PST One of the most important aims of contemporary scientific research is finding out what makes the production of entropy predominate. This aim explains the current interest in studying mesoscopic systems, which are not as small as individual atoms but nevertheless display well-defined quantum behavior. |
| Marine bacterium sheds light on control of toxic metals Posted: 14 Jan 2019 01:11 PM PST An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper. Although essential to life, metal ions can also generate reactive oxygen species (ROS) -- highly reactive molecules that damage cells as they try to form bonds with other molecules. In humans, reactive oxygen species are linked to aging and also to diseases such as cancers. |
