Developmental processes in all living organisms are controlled by genes. At the same time there is a continuous metabolism taking place. Recent research in Austria has analyzed this interaction in flowering plants. For the first time, changes in metabolism were linked to 3-D morphometric data using micro-computed tomography (micro-CT) for the first time.
The discovery of buckyballs helped usher in the nanotechnology era. Now, researchers from Brown Univ. and colleagues from China have shown that boron, carbon’s neighbor on the periodic table, can form a cage-like molecule similar to the buckyball. Until now, such a boron structure had only been a theoretical speculation.
The creators of a unique kit containing 3-D printed anatomical body parts say it will revolutionize medical education and training, especially in countries where cadaver use is problematic. The “3D Printed Anatomy Series”, developed by experts in Australia, is thought to be the first commercially available resource of its kind. The kit contains no human tissue, yet it provides all the major parts of the body required to teach anatomy.
Scientists in Israel have recently constructed, for the first time, a photonic router that enables routing of single photons by single photons. At the core of the device is an atom that can switch between two states. The state is set just by sending a single particle of light, or photon, from the right or the left via an optical fiber. The innovation could help overcome difficulties in building quantum computers.
A cheap, portable, microchip-based test for diagnosing type-1 diabetes could speed up diagnosis and enable studies of how the disease develops. Handheld microchips distinguish between the two main forms of diabetes mellitus, which are both characterized by high blood-sugar levels but have different causes. Until now, making the distinction has required a slow, expensive test available only in sophisticated healthcare settings.
Marilyn Minus, a materials expert and assistant professor at Northeastern Univ., is exploring directed self-assembly methods using carbon nanotubes and polymer solutions. So far, she’s used the approach to develop a polymer composite material that is stronger than Kevlar yet much lighter and less expensive. Minus is now expanding this work to incorporate more polymer classes: flame retardant materials and biological molecules.
Rutgers Univ. researchers have developed a technology that could overcome a major cost barrier to make clean-burning hydrogen fuel. The new catalyst is based on carbon nanotubes and may rival cost-prohibitive platinum for reactions that split water into hydrogen and oxygen.
Biophysics researchers have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion process that powers life on our planet. The findings could potentially help engineers make more efficient solar cells and energy storage systems.
In the movie “Terminator 2,” the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.
The song says a spoonful of sugar helps the medicine go down, but a study says that kind of imprecise measurement can lead to potentially dangerous dosing mistakes. The results, published online in Pediatrics, underscore recommendations that droppers and syringes that measure in milliliters be used for liquid medicines—not spoons.
Citing an anthrax scare and other safety problems, the Centers for Disease Control and Prevention on Friday said it shut down two research labs and stopped shipping highly dangerous germs to other labs. An incident at one of the closed Atlanta laboratories could have accidentally exposed workers in three labs to anthrax last month. A second, previously undisclosed problem earlier this year involved deadly bird flu.
The addition of elements to the surface of graphene can modify the material’s physical and chemical properties, potentially extending the range of possible applications. Recently performed theoretical calculations at RIKEN in Japan show that the addition of oxygen to graphene on copper substrates results in enhanced functionalization. The resulting structure, known as an enolate, make support applications that require catalytic response.
According to recent research in the U.K. , use of electronic health records to understand the best available treatment for patients, from a range of possible options, is more efficient and less costly for taxpayers than the existing clinical trial process.
Perovskites continue to entice materials scientists with their mix of conductivity, ferroelectricity, ferromagnetism, and catalytic activity. In recent years, scientists realized that they could vastly improve the properties of perovskites by assembling them into thin films, but nobody knew the reason why. But studying the chemistry layer-by-layer, experts working with x-ray beamline at Argonne National Laboratory are getting close.
Terracon Corp. has introduced of new production-sized mixing tank, the TerraPro Mixer, designed to meet the need of life sciences companies for a high-performance mixer that can be delivered quickly. The TerraPro Mixer is ideal for media and buffer preparation.
Bruker has announced the release of Inspire, the first integrated scanning probe microscopy infrared system for 10-nm spatial resolution in chemical and materials property mapping. The new and unique Inspire system incorporates Bruker’s proprietary PeakForce IR mode to enable nanoscale infrared reflection and absorption mapping for a wide range of applications.
The Allen Institute for Brain Science and research partners have collaborated to launch a new technology called Virtual Finger, which allows scientists to move through digital images of small structures like neurons and synapses using the flat surface of their computer screens. The development is intended to make 3-D imaging studies orders of magnitude more efficient.
Lighting is crucial to the art of photography, but they are cumbersome and difficult to use properly. Researchers at Massachusetts Institute of Technology and Cornell Univ. aim to change that by providing photographers with squadrons of small, light-equipped autonomous robots that automatically assume the positions necessary to produce lighting effects specified through a simple, intuitive, camera-mounted interface.
The South Korean display panel maker LG has developed an 18-inch flexible display that can be rolled into the shape of a thin cylinder, a step toward making a large display for flexible TVs. Although not as sharp as the latest ultra-high definition flat screens, the new display has a resolution of 1200 pixels by 810 pixels and maintains its function when it is rolled up.
The solar panels that Idaho inventor Scott Brusaw has built aren't meant for rooftops. They are meant for roads, driveways, parking lots, bike trails and, eventually, highways. Brusaw, an electrical engineer, says the hexagon-shaped panels can withstand the wear and tear that comes from inclement weather and vehicles, big and small, to generate electricity.
Defining what makes a star “sun-like" is as difficult as defining what makes a planet "Earth-like." A solar twin should have a temperature, mass and spectral type similar to our sun. We also would expect it to be about 4.5 billion years old. However, it is notoriously difficult to measure a star's age so astronomers usually ignore age when deciding if a star counts as "sun-like."
Nuclear engineers at Oregon State Univ. have developed a small, portable and inexpensive radiation detection device that should help people all over the world better understand the radiation around them, its type and intensity and whether or not it poses a health risk.
Meet the seven new dwarf galaxies. Yale Univ. astronomers, using a new type of telescope made by stitching together telephoto lenses, recently discovered seven celestial surprises while probing a nearby spiral galaxy. The previously unseen galaxies may yield important insights into dark matter and galaxy evolution, while possibly signaling the discovery of a new class of objects in space.
Scientists at Stanford Univ. and the Dept. of Energy (DOE)’s SLAC National Accelerator Laboratory have found a way to estimate uncertainties in computer calculations that are widely used to speed the search for new materials for industry, electronics, energy, drug design and a host of other applications. The technique, reported in Science, should quickly be adopted in studies that produce some 30,000 scientific papers per year.
