Computer scientists have developed a technique that uses anisotropic triangles (triangles with sides that vary in length depending on their direction) to make 3-D images. The technique finds a practical application of the Nash embedding theorem, which was named after mathematician John Forbes Nash Jr., subject of the film "A Beautiful Mind".
Within the pharmaceutical industry, the rapid identification, elucidation and characterization of synthetic, process impurities and degradation products is an intense and comprehensive undertaking. In the development of a formulated drug substance, the U.S. Food and Drug Administration (FDA) requires that all impurities introduced in the proposed process above 0.1% must be isolated and fully characterized.
A city car under development at Ohio State Univ. has no engine, no transmission and no differential. It weighs half as much as a conventional car and is powered by battery-power motors in each of its four wheels. But it needs help from a computer to stay stable and operating smoothly, which is why the research team is designing sophisticated algorithms for the vehicle's onboard computer.
Increasingly, medical professionals are using electronic medical systems that provide lists of laboratory tests from which medical professionals can choose. Now, a Univ. of Missouri researcher and her colleagues have studied how to modify these lists to ensure health professionals order relevant tests and omit unnecessary lab tests, which could result in better care and reduced costs for patients.
Iris scans, fingerprint scans, facial and voice recognition are tools that improve security while making our lives easier, says Stephen Elliott, director of international biometric research at Purdue Univ. His basement lab is a place where emerging biometric technologies are tested for weaknesses before they can go mainstream.
As transistors get smaller, they also become less reliable. So far, computer-chip designers have been able to work around that problem, but in the future, it could mean that computers stop improving at the rate we’ve come to expect. A third possibility, which some researchers have begun to float, is that we could simply let our computers make more mistakes.
In the hugely popular game Minecraft, players can freely build and create their own world by mining and stacking different types of bricks in a sandbox-like environment. Because of its customizable dynamic, the game has also become a background platform for many user-generated modifications, or "mods". Researchers and the developers of Minecraft have built a new Google-funded mod that introduces quantum mechanics into the game's landscape.
Honeycomb sandwich panels, with their high strength-to-weight ratios, have significant advantages over monocoque construction for certain applications. Twin-skinned plates/shells with a honeycomb core are widely used in the aerospace industry for structures such as aircraft fuselages, engine cowlings and impact protection shields.
Advances in computer storage have created collections of data so huge that researchers often have trouble uncovering critical patterns in connections among individual items, making it difficult for them to realize fully the power of computing as a research tool. Now, computer scientists at Princeton Univ. have developed a method that offers a solution to this data overload.
Accurate and rapid testing for drug toxicity just became easier, thanks to a half-dozen Rice Univ. student interns working at Houston-based startup Nano3D Biosciences (n3D). The bioengineering and nanoscale physics students just wrapped up a year-long effort to aid the company in developing a new method for conducting high-throughput, in vitro cytotoxicity assays.
Oscilloscopes display and measure the wave shape of an electrical signal. High-performance oscilloscopes, which are capable of measuring signals at very high frequencies, are primarily used in high-speed applications. Agilent Technologies recently released the Infiniium 90000 Q-Series oscilloscope, which is the world’s highest bandwidth commercially available real-time oscilloscope and the first to reach the 60-GHz barrier.
The modeling and simulation of various manufacturing processes is important because, in many cases, it’s impractical or even impossible to measure the specific operating parameters involved that contribute to the resulting products. This is particularly true in high-temperature processes like blast furnaces or the welding of large metal structures such as those used in shipbuilding and reactor vessels.
Over the past three years, 300,000 gamers have helped scientists with genomic research by playing Phylo, an online puzzle game. Now, the McGill Univ. researchers who developed the game are making this crowd of players available to scientists around the globe. The idea is to put human talent to work to improve on what is already being done by computers in the field of comparative genomics.
For those wanting to keep their distance from health threats like E. coli-contaminated lettuce or the flu, there are two upcoming apps for that. Pacific Northwest National Laboratory hosted a competition last summer where graduate students used Android development tools and web-based analytics to design mobile apps that could help fight the threats of food-related illnesses and the flu.
For NASA, data pour in every day like rushing rivers. Spacecraft monitor everything from our home planet to faraway galaxies, beaming back images and information to Earth. All those digital records need to be stored, indexed and processed so that researchers can use the data to understand Earth and the universe beyond. Now, software engineers are coming up with new strategies for managing such large and complex data streams.
Researchers have developed software that allows them to map unknown environments based on the movement of a swarm of insect cyborgs, or “biobots.” The software would also allow public safety officials to determine the location of radioactive or chemical threats, if the biobots have been equipped with the relevant sensors.
Details have been released by IBM Research on Watson-related cognitive technologies that are expected to help physicians make more informed and accurate decisions faster and to cull new insights from electronic medical records (EMR). The new computing capabilities allow for a more natural interaction between physicians, data and EMRs.

Food and Drug Administration officials say they will now begin regulating applications and gadgets that work with smartphones to take medical readings and help users monitor their health.
North Carolina State Univ. researchers have developed a way for search engines to provide users with more accurate, personalized search results. The challenge in the past has been how to scale this approach up so that it doesn’t consume massive computer resources. Now the researchers have devised a technique for implementing personalized searches that is more than 100 times more efficient than previous approaches.
Computers will someday soon automatically provide short video digests of a day in your life, your family vacation or an eight-hour police patrol, say computer scientists at the Univ. of Texas at Austin. The researchers are working to develop tools to help make sense of the vast quantities of video that are going to be produced by wearable camera technology such as Google Glass and Looxcie.
From Sept. 16 to 18, 2013, top leaders from the White House and U.S. science agencies and their international colleagues will gather for three days in Washington, D.C., for a major meeting of the Research Data Alliance (RDA). More than 850 researchers and data experts belong to the RDA, which focuses on the development and adoption of common tools, harmonized standards and infrastructure needed for data sharing by researchers.
Richard Van As, a South African carpenter, lost four fingers from his right hand to a circular saw two years ago. He was unable to afford the tens of thousands of dollars to get a myoelectric hand, which detects a muscle's electric impulses to activate an artificial limb. He decided to build his own hand, made from cables, screws and thermoplastic, using only the Internet and a 3-D printer. He has since fitted 170 people with Robohands.
