Opening communication lines between propulsion and airflow poses new questions Posted: 11 Oct 2018 10:34 AM PDT On the runway to more fuel-efficient aircraft, one alternative propulsion scheme being explored is an array of electrically powered ducted fans. The fans are distributed across the wing span or integrated into the wing. Researchers have gained new understanding in how the fans and especially their precise placement on the aircraft can affect the cross-conversation between propulsion and the airflow around the wing. |
Posted: 11 Oct 2018 08:24 AM PDT For the first time, physicists have built a unique topological insulator in which optical and electronic excitations hybridize and flow together. |
Posted: 11 Oct 2018 08:24 AM PDT Researchers from Japan have taken a step toward faster and more advanced electronics by developing a way to better measure and manipulate conductive materials through scanning tunneling microscopy. |
The culprit of superconductivity in cuprates Posted: 11 Oct 2018 06:05 AM PDT Researchers have uncovered an underlying mechanism related to the materials dependence in copper-based high-temperature superconductors. The research may open a new avenue for designing materials with high-temperature superconductivity. |
Versatile molecular system extends the promise of light-activated switches Posted: 10 Oct 2018 10:24 AM PDT A newly-developed molecule is easy to make, simple to work with and may potentially be used for the development of targeted medications and high-density memory devices with the volume of a speck of a dust. |
Color-changing contact lens could enhance monitoring of eye disease treatments Posted: 10 Oct 2018 09:49 AM PDT For all the good they do, eye drops and ointments have one major drawback: It's hard to tell how much of the medication is actually getting to the eye. Now scientists report that they have developed a contact lens that changes color as drugs are released. This visual indicator could help eye doctors and patients readily determine whether these medications are where they should be. |
Innovative sensing technique could improve greenhouse gas analysis Posted: 10 Oct 2018 08:19 AM PDT An international team of researchers has used an unconventional imaging technique known as ghost imaging to make spectroscopic measurements of a gas molecule. |
A break from the buzz: Bees go silent during total solar eclipse Posted: 10 Oct 2018 07:55 AM PDT In an unprecedented study of a solar eclipse's influence on bee behavior, researchers organized citizen scientists and elementary school classrooms to set up acoustic monitoring stations to listen in on bees' buzzing -- or lack thereof -- as the August 2017 total solar eclipse passed over North America. The results were clear and consistent at locations across the United States: Bees stopped flying during the period of total solar eclipse. |
Engineers develop process to 3-D print cells to produce human tissue such as ligaments and tendons Posted: 10 Oct 2018 07:55 AM PDT Scientists have developed a method to 3-D print cells to produce human tissue such as ligaments and tendons to greatly improve a patient's recovery. A person with a badly damaged ligament, tendon, or ruptured disc could simply have new replacement tissue printed and ultimately implanted in the damaged area. |
Nail polishes with 'n-free' labels are not necessarily free of toxic compounds Posted: 10 Oct 2018 06:36 AM PDT Consumers are growing more knowledgeable about the potential health effects of nail polish, and manufacturers have taken action. They have started removing potentially toxic ingredients and labeling their products as being free of those substances. However, these labels aren't always accurate, and reformulated products aren't necessarily safer, according to a new report. |
Synergy in two-dimensional materials, membranes research clear in professor's new work Posted: 10 Oct 2018 06:36 AM PDT Two-dimensional materials and membranes were once separate fields, but synergistic opportunities are resulting in exciting new developments at their intersection. |
Supercomputer predicts optical properties of complex hybrid materials Posted: 09 Oct 2018 08:50 AM PDT Computational models of layered hybrid perovskites open new material design space for light-based applications such as LEDs and water purification. |
Artificial intelligence helps reveal how people process abstract thought Posted: 09 Oct 2018 08:50 AM PDT As artificial intelligence becomes more sophisticated, much of the public attention has focused on how successfully these technologies can compete against humans at chess and other strategy games. A philosopher has taken a different approach, deconstructing the complex neural networks used in machine learning to shed light on how humans process abstract learning. |
Newly discovered bacterium rids problematic pair of toxic groundwater contaminants Posted: 09 Oct 2018 08:50 AM PDT Researchers have detailed the discovery of the first bacterium known capable of simultaneously degrading the pair of chemical contaminants -- 1,4-Dioxane and 1,1-DCE. |
