If you picture a solar panel, it’s most likely dark blue or black, and rigid and flat. Now...
Lightning darts across the sky in a flash. And even though we can use lightning rods to increase...
In a study that contradicts the received wisdom on health impacts of climate change, scientists say that we shouldn’t expect substantial reduction in winter deaths as a result of global warming. This new research is published in Environmental Research Letters.
The tiny hairs of Saharan silver ants possess crucial adaptive features that allow the ants to regulate their body temperatures and survive the scorching hot conditions of their desert habitat. According to a new research paper, the unique triangular shape and internal structure of the hairs play a key role in maintaining the ant’s average internal temperature below the critical thermal maximum of 53.6 C (128.48 F).
Researchers have found an easy way to produce carbon nanoparticles that are small enough to evade the body's immune system, reflect light in the near-infrared range for easy detection and carry payloads of pharmaceutical drugs to targeted tissues. Unlike other methods of making carbon nanoparticles, the new approach generates the particles in a few hours and uses only a handful of ingredients, including store-bought molasses.
Like homing pigeons, humans have a nose for navigation because our brains are wired to convert smells into spatial information, new research shows. While humans may lack the scent-tracking sophistication of, say, a search-and-rescue dog, we can sniff our way, blindfolded, toward a location whose scent we’ve smelled only once before.
Researchers have used ultra-short pulses of x-rays to film shock waves in diamonds. The study headed by DESY scientists opens up new possibilities for studying the properties of materials. Thanks to the extremely bright and short x-ray flashes, the researchers were able to follow the rapid, dynamic changes taking place in the shock wave with a high spatial, as well as a high temporal, resolution.
NASA's Hubble Space Telescope has detected a stratosphere, one of the primary layers of Earth's atmosphere, on a massive and blazing-hot exoplanet known as WASP-33b.
Planets with volcanic activity are considered better candidates for life than worlds without such heated internal goings-on. Now, graduate students at the Univ. of Washington have found a way to detect volcanic activity in the atmospheres of exoplanets, or those outside our solar system, when they transit, or pass in front of their host stars.
Origami, the Japanese art of paper folding, can be used to create beautiful birds, frogs and other small sculptures. Now a Binghamton Univ. engineer says the technique can be applied to building batteries, too. Seokheun "Sean" Choi developed an inexpensive, bacteria-powered battery made from paper.
Univ. of California, Davis, researchers have identified the molecular interactions that allow capsaicin to activate the body’s primary receptor for sensing heat and pain, paving the way for the design of more selective and effective drugs to relieve pain. Capsaicin is the ingredient that makes chili peppers spicy and hot.
Scientists have now monitored the chemical processes during a photographic exposure at the level of individual nanoscale grains in real-time. The advanced experimental method enables the investigation of a broad variety of chemical and physical processes in materials with millisecond temporal resolution.
Computers and water typically don't mix, but in Manu Prakash's lab, the two are one and the same. Prakash, an assistant professor of bioengineering at Stanford, and his students have built a synchronous computer that operates using the unique physics of moving water droplets.
Researchers from Brown University are developing a new algorithm to help robots better plan their actions in complex environments. It’s designed to help robots be more useful in the real world, but it’s being developed with the help of a virtual world — that of the video game Minecraft.
Dandelions are modest plants that are an excellent alternative source for a raw material of high demand: natural rubber, the fundamental ingredient in rubber products. Fraunhofer researchers have established the basis for the large-scale production of high quality rubber with Russian dandelion.
If you lived on one of Pluto's moons, you might have a hard time determining when, or from which direction, the sun will rise each day. Comprehensive analysis of data from NASA's Hubble Space Telescope shows that two of Pluto's moons, Nix and Hydra, wobble unpredictably.
What if your doctor told you that your weight is somewhere between 100 and 400 lbs.? With any ordinary scale every patient can do better at home. Yet, one patient can't: the Milky Way. Even though today we peer deeper into space than ever before, our home galaxy's weight is still unknown to about a factor of four.
Male moths locate females by navigating along the latter's pheromone (odor) plume, often flying hundreds of meters to do so. Two strategies are involved to accomplish this: males must find the outer envelope of the pheromone plume, and then head upwind. Can understanding such insect behavior be useful for robotics research?
Engineers at Massachusetts Institute of Technology and the Univ. of California at San Diego have devised a new way to detect cancer that has spread to the liver, by enlisting help from probiotics, beneficial bacteria similar to those found in yogurt. Many types of cancer, including colon and pancreatic, tend to metastasize to the liver. The earlier doctors can find these tumors, the more likely that they can successfully treat them.
The DNA encoding all life on Earth is made of four building blocks called nucleotides, commonly known as “letters,” that line up in pairs and twist into a double helix. Now, two groups of scientists are reporting for the first time that two new nucleotides can do the same thing, raising the possibility that entirely new proteins could be created for medical uses.
Every year, an estimated half-million Americans undergo surgery to have a stent prop open a coronary artery narrowed by plaque. But sometimes the mesh tubes get clogged. Scientists report in ACS Nano a new kind of multi-tasking stent that could minimize the risks associated with the procedure. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job.
A team of researchers has, for the first time, predicted the occurrence of aurorae visible to the naked eye on a planet other than Earth. Mars' upper atmosphere may be indeed closer to Earth's than previously thought. Researchers showed that the upper atmosphere of Mars glows blue depending on the activity of the sun.
A Univ. of Melbourne study shows that glancing at a grassy green roof for only 40 sec markedly boosts concentration. The study, published in the Journal of Environmental Psychology, gave 150 students a boring, attention-sapping task. The students were asked to press a key as a series of numbers repeatedly flashed on a computer screen, unless that number was three.
Rice Univ. researchers have developed a method to detect rare DNA mutations with an approach hundreds of times more powerful than current methods. The technique allows the researchers to find a figurative needle in a haystack that’s smaller than any needle.
Most people see defects as flaws. A few Michigan Technological Univ. researchers, however, see them as opportunities. Twin boundaries may present an opportunity to improve lithium-ion batteries. The twin boundary defects act as energy highways and could help get better performance out of the batteries. This finding turns a previously held notion of material defects on its head.
Last summer, MIT researchers published a paper describing an algorithm that can recover intelligible speech from the analysis of the minute vibrations of objects in video captured through soundproof glass. In June, researchers from the same groups will describe how the technique can be adapted to infer material properties of physical objects, such as stiffness and weight, from video.
Fans of homebrewed beer and backyard distilleries already know how to employ yeast to convert sugar into alcohol. But a research team led by UC Berkeley bioengineers has gone much further by completing key steps needed to turn sugar-fed yeast into a microbial factory for producing morphine and potentially other drugs, including antibiotics and anti-cancer therapeutics.
