Using high speed video, transmission electron microscopy, spectrometry, energy dispersive x-ray spectroscopy, and computer modeling, a Univ. of California, Berkeley graduate student has unraveled the mystery of the disco clams flashing “lips”. Most people assumed the glowing mantle was the result of bio-luminescence, but Lindsey Dougherty has found it is caused by something else entirely.
Researchers compare the processing of biological fluid samples with searching for a needle in a haystack—only in this case, the haystack could be diagnostic samples, and the needle might be tumor cells present in just ppm concentrations. Now, a new way of processing these samples could make such detections possible in real time.
Think of the human body as an intricate machine whose working parts are proteins: molecules that change shape to enable our organs and tissues to perform tasks such as breathing, eating or thinking. Of the millions of proteins, 500 in the kinase family are particularly important to drug discovery. Kinases are messengers: They deliver signals that regulate and orchestrate the actions of other proteins.
The summer weather is here, and if you’ve been out in the sun, you’re probably craving some ice cream to cool off. In the American Chemical Society’s latest Reactions video, American Univ. Asst. Prof. Matt Hartings, breaks down the chemistry of this favorite frozen treat, including what makes ice cream creamy or crunchy, and why it is so sweet.
Without a specific search term in mind, it can be surprisingly hard to find information on the Internet , or to know how to start searching. To help, computer scientists have created the first fully automated computer program that teaches everything there is to know about any visual concept. Called Learning Everything about Anything (LEVAN), the program searches millions of books and images to learn all possible variations of a concept.
Thirty years have passed since 3-D printers first appeared, but only recently have they hinted at a new era of manufacturing. The first working 3-D printer was created in 1984 by Chuck Hull of 3D Systems Corp. This early device, based on stereolithography, gave way to the first truly practical 3-D printing technology patented by the Massachusetts Institute of Technology in 1993.
Scientists in Switzerland have invented a molecule that can easily and quickly show how much drug is in a patient’s system. All that is needed to perform accurate measurements is a conventional digital camera. The result of innovative protein engineering and organic chemistry, the molecule has been shown to work on a range of common drugs for cancer, epilepsy and immunosuppression.
The need for robust password security has never been more critical than now, as people use smartphones or tablets to pay bills and store personal information. A new Rutgers study shows that free-form gestures can be used to unlock phones and grant access to apps. These gestures are less likely to be observed and reproduced than than traditional methods such as typed passwords.
Rice Univ. scientists have created an Earth-friendly way to separate carbon dioxide from natural gas at wellheads. A porous material invented by the Rice laboratory of chemist James Tour sequesters carbon dioxide, a greenhouse gas, at ambient temperature with pressure provided by the wellhead and lets it go once the pressure is released. The material shows promise to replace more costly and energy-intensive processes.
A Swiss-made solar-powered aircraft has made a successful inaugural flight as its makers prepare for what they hope will be the first round-the-world solar flight. The aircraft spent 2 hours and 17 minutes in the air above western Switzerland early Monday. The Solar Impulse 2 is a bigger and better version of a single-seat prototype that first took flight five years ago and can theoretically stay airborne indefinitely.
The first preclinical study of a new Rice Univ.-developed anticancer technology found that a novel combination of existing clinical treatments can instantaneously detect and kill only cancer cells without harming surrounding normal organs. The research reports that Rice’s “quadrapeutics” technology was 17 times more efficient than conventional chemoradiation therapy against aggressive, drug-resistant head and neck tumors.
The SuperDraco thruster, an engine that will power SpaceX’s Dragon spacecraft to orbit, has completed a test regimen held over the last month at SpaceX’s Rocket Development Facility in Texas. This qualification test involves a variety of conditions conditions including multiple starts, extended firing durations and extreme off-nominal propellant flow and temperatures.
A team of researchers has successfully tracked single molecules inside living cells with carbon nanotubes. Through this new method, the researchers found that cells stir their interiors using the same motor proteins that serve in muscle contraction. The study, which sheds new light on biological transport mechanisms in cells, appears in Science.
At this year’s IEEE International Conference on Robotics and Automation, a research team introduced a new wrinkle on the idea of printable robots: bakable robots. In two new papers, the researchers demonstrate the promise of printable robotic components that, when heated, automatically fold into prescribed 3-D configurations.
Neuroscientists, engineers and physicians are teaming up for an ambitious five-year, $26 million project to develop new techniques for tackling mental illness. By using devices implanted in the brain, they aim to target and correct malfunctioning neural circuits in conditions such as clinical depression, addiction and anxiety disorders.
