The millions of people worldwide who suffer from the painful bladder disease known as interstitial cystitis (IC) may soon have a better, long-term treatment option, thanks to a controlled-release, implantable device invented by Massachusetts Institute of Technology Prof. Michael Cima and other researchers. The device is a pretzel-shaped silicone tube that could be inserted into the bladder, slowly releasing lidocaine over two weeks.
The phase-out of traditional incandescent bulbs in the U.S. and elsewhere, as well as a growing interest in energy efficiency, has given LED lighting a sales boost. That trend could be short-lived as key materials known as rare earth elements become more expensive. Scientists at Rutgers Univ., however, have now designed new materials for making household LED bulbs without using these ingredients.
Scientists report that they have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide. This finding has resulted in a unique electric generator and could point the way to mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.
The CAPCELL PAK from JM Science is a high-performance liquid chromatography (HPLC) column integrating the excellent separation performance of silica-based, polymer-coated packing material. CAPCELL PAK essentially provides columns of reversed phase partition mode, normal phase partition mode, and ion exchange mode.
Keithley Instruments has developed a free app for Android-based smartphones and tablets that interacts with a Keithley Series 2600B SourceMeter SMU instrument via its front panel USB interface. The app, called IVy, offers benchtop Series 2600B instrument users a fast, easy-to-use touchscreen tool for characterizing 2- and 3-terminal devices.
Iron catalysts remove oxygen inexpensively, but are susceptible to rust or oxidation in biofuel production. Precious metals that resist corrosion are even less efficient at removing oxygen. But adding just a touch of palladium to the iron produces a catalyst that quickly removes oxygen atoms, easily releases the desired products, and doesn't rust, according to scientists at Pacific Northwest National Laboratory and Washington State Univ.
The European Space Agency has confirmed the time and place it will attempt to land the first spacecraft on a comet. The unmanned probe Rosetta will release a 100-kg (220-lb) lander on Nov. 12 in a maneuver that will take about seven hours.
Univ. of California, Berkeley scientists have taken proteins from nerve cells and used them to create a “smart” material that is extremely sensitive to its environment. This marriage of materials science and biology could give birth to a flexible, sensitive coating that is easy and cheap to manufacture in large quantities.
Mark Skwarek has raised over $30,000 on the group fundraising site Kickstarter to launch Semblance Augmented Reality (AR). His company aims to liberate video games from the TV and turn them into physical experiences, such as battling militants in New York’s Central Park. He's poised to release Semblance AR's first app for iOS and Android phones.
Researchers from the Univ. of Sheffield have found vital new evidence on how to target and reverse the effects caused by one of the most common genetic causes of Parkinson’s. Mutations in a gene called LRRK2 carry a well-established risk for Parkinson’s disease, however the basis for this link is unclear.
Using 3-D printing and novel semiconductors, researchers at Oak Ridge National Laboratory have created a power inverter that could make electric vehicles lighter, more powerful and more efficient. At the core of this development is wide bandgap material made of silicon carbide with qualities superior to standard semiconductor materials.
In a recent article published in the Review of Scientific Instruments, a research team led by scientists at Lawrence Livermore National Laboratory describe a technique for 3-D image processing of a high-speed photograph of a target, "freezing" its motion and revealing hidden secrets. This technique is particularly applicable in targets that are "shocked."
The proteins that drive DNA replication are some of the most complex machines on Earth and the process involves hundreds of atomic-scale moving parts that rapidly interact and transform. Now, scientists have pinpointed crucial steps in the beginning of the replication process, including surprising structural details about the enzyme that "unzips" and splits the DNA double helix so the two halves can serve as templates for DNA duplication.
Officials at a Chicago-based startup, Sagamore-Adams Laboratories LLC, say innovations discovered in Purdue University's School of Nuclear Engineering are being commercialized to address challenges in improving radiation detection and making sealants and adhesives safer. They have developed technology that could lead to radiation sensors that cost less and provide better information than traditional sensors.
NASA’s MAVEN spacecraft has provided scientists their first look at a storm of energetic solar particles at Mars and produced unprecedented ultraviolet images of the tenuous oxygen, hydrogen and carbon coronas surrounding the Red Planet. In addition, the new observations allowed scientists to make a comprehensive map of highly variable ozone in the Martian atmosphere underlying the coronas.
