To learn new motor skills, the brain must be plastic: able to rapidly change the strengths of connections between neurons, forming new patterns that accomplish a particular task. However, if the brain were too plastic, previously learned skills would be lost too easily. A new computational model explains how the brain maintains the balance between plasticity and stability, and how it can learn similar tasks without interference.
Univ. of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where stability is important.
The Titan Arm, a robotic device invented by Univ. of Pennsylvania engineering students, looks and sounds like part of a superhero's costume. But its creators say it's designed for ordinary people—those who need either physical rehabilitation or a little extra muscle for their job. The arm can help its wearer carry an additional 40 pounds.
Even as Silicon Valley speaks out against the U.S. government's surveillance methods, technology companies are turning a handsome profit by mining personal data. Tarnished by revelations that the National Security Agency trolls deep into the everyday lives of Web surfers, companies like Apple, Facebook, Google, and Microsoft are aggressively battling any perception that they voluntarily give the government access to users' information.
With one stomp of his foot, Zhong Lin Wang illuminates a thousand light-emitting diode (LED) bulbs, with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps from a fingertip to a doorknob when you walk across carpet on a cold, dry day. Wang and his research team have learned to harvest this power and put it to work.
Students may soon be able to touch some of the theoretical concepts they are taught in their physics classes thanks to a new idea devised by a group of researchers in England. In just eight hours and at the cost of around 15 euros, they were able to use a commercially available 3-D printer to create their own object based on a mathematical model that described how forest fires can be started and how they eventually spread over time.
A connected vehicle network, with vehicles exchanging information with the highway infrastructure and other vehicles using wireless communications, could improve traffic safety, mobility and environmental impacts. Southwest Research Institute, which has considerable expertise in intelligent vehicle development, is now serving as an official Connected Vehicle Affiliated Test Bed for this technology.
An ultrasonic microscope emits a high frequency sound at an object, and the reflected sound captured by its lens is converted into a 2-D image of the object under scrutiny. Prof. Naohiro Hozumi in Japan is developing the technology to monitor living tissue and cell specimens for medical purposes.
The information and communications technologies (ICT) industry, and the significant level of R&D that supports it, is driven by constant change in consumer preferences, market demand and technological evolution. The ICT industry is the largest private-sector R&D investor in the U.S., performing nearly one-third of the total.
Transistors, the workhorses of the electronics world, are plagued by leakage current. This results in unnecessary energy losses, which is why smartphones and laptops, for example, have to be recharged so often. Researchers have recently shown that this leakage current can be radically reduced by “squeezing” the transistor with a piezoelectric material. Using this approach, they have surpassed the theoretical limit for leakage current.
Are electrons truly round? More specifically, is the electron’s charge between its poles uniform? A group at JILA has tackled this difficult question and has developed a method of spinning electric and magnetic fields around trapped molecular ions to measure the tiny electrons. They haven’t yet matched other electric dipole moment measurement techniques, but eventually the new method should surpass them.
A researcher team from Spain and Italy say that when envisioning in vivo microrobots of the future, we should forget cogwheels, pistons and levers. These miniature robots will be soft, and behave much like euglenids, tiny unicellular aquatic animals. Their work in studying these creatures have given them insights on how to design soft robots with effective mechanical structures.
High-temperature superconductors exhibit a frustratingly varied catalog of odd behavior, such as electrons that arrange themselves into stripes or refuse to arrange themselves symmetrically around atoms. Now two physicists propose that such behaviors, and superconductivity itself, can all be traced to a single starting point, and they explain why there are so many variations.
Researchers have combined cutting-edge experimental techniques and computer simulations to find a new way of predicting how water dissolves crystalline structures like those found in natural stone and cement. The research could have wide-ranging impacts in diverse areas, including water quality and planning, environmental sustainability, corrosion resistance and cement construction.
The ChemCam laser instrument aboard NASA’s Curiosity rover fired its 100,000th shot recently, chronicling its adventures on Mars with a coffee-table-book’s worth of spectral data that might rival snapshots gathered during a long and satisfying family vacation here on Earth. ChemCam zaps rocks with a high-powered laser to determine their composition and carries a camera that can survey the Martian landscape.
The Information Age will get a major upgrade with the arrival of quantum processors faster and more powerful than today’s supercomputers. For the benefits of this new Information Age 2.0 to be fully realized, however, quantum computers will need fast and efficient multi-directional light sources. While quantum technologies remain grist for science fiction, a team of researchers has taken an important step towards efficient light generation.
Two German researchers have used a simple energy balance analysis to explain how the Earth’s water cycle responds differently to heating by sunlight than it does to warming due to a stronger atmospheric greenhouse effect. This difference, their work shows, implies that reflecting sunlight to reduce temperatures may have unwanted effects on the Earth’s rainfall patterns.
DNAnexus has announced a collaboration with Stanford Univ. that has resulted in a new 1000 Genomes Project data set of genetic variation. Launched in January 2008, the 1000 Genomes Project was the first international effort to sequence a large number of individual genomes with the goal of developing a comprehensive and freely accessible resource on human genetic variation.
Sometimes the cure can be worse than the disease. Pharmaceutical drugs are known for their potential side effects, and an important aspect of personalized medicine is to tailor therapies to individuals to reduce the chances of adverse events. Now researchers from North Carolina State Univ. have updated an extensive toxicology database so that it can be used to track information about therapeutic drugs and their unintentional toxic effects.
An international multidisciplinary team including researchers at the Univ. of Illinois at Urbana/Champaign and the National Institute of Biomedical Imaging and Bioengineering has developed a sophisticated ”electronic skin” that adheres non-invasively to human skin, conforms well to contours, and provides a detailed temperature map of any surface of the body.
The outer shell of a droplet of oil on a surface has a thin skin which allows it to hold its shape like a small dome. Researchers at the Univ. of Missouri have developed a technique to form a virtual wall for oily liquids that will help confine them to a certain area, aiding researchers who are studying these complex molecules. The finding could also help halt industrial oil spills.
A collaboration of physicists and engineers has found a new way to control electron spins not with a magnetic field but with a mechanical oscillator. This demonstration of electron spin resonance that’s “shaken, not stirred” showed that an oscillator can drive the transitions of electron spins within defects commonly found in the crystal lattice of a diamond.
