Coating the mouth with BPA-containing food does not lead to higher than expected levels of BPA in blood, according to a new study. The study concludes that oral exposure does not create a risk for high exposures. BPA, also known as bisphenol A, is used to make some plastics and to seal canned food containers against bacterial contamination. Food, which picks up trace amounts of BPA from packaging, is the major source of human exposure.
The idea of computing systems based on controlling atomic spins just got a boost from new research performed at MIT and Brookhaven National Laboratory. By constructing tiny "mirrors" to trap light around impurity atoms in diamond crystals, the team dramatically increased the efficiency with which photons transmit information about those atoms' electronic spin states, which can be used to store quantum information.
McPherson’s Deep UV Luminescence Spectrophotometer extends capabilities for material science and novel, efficient lighting research. McPherson has announce improved optical characterization systems for spectral measurements from the vacuum ultraviolet (VUV) to the near infrared. The vacuum ultraviolet universal spectrophotometer is an optical test system optimized for emitting samples like phosphors or photo- and electro-luminescent crystals.
The Rad-icon 3030 detector features 3,096 x 3,100 pixel resolution, an active area of 30.6 x 30.7 cm and 99-micron pixel size. Rad-icon detectors deliver real-time frame rates of up to 30 fps, high sensitivity and superb resolution in a large area device that is fully integrated and available with a fast, reliable Gigabit Ethernet or Camera Link interface.
Clippard Instrument Laboratory Inc., manufacturer of miniature pneumatic products, has just released their all-new full-line catalog. This new edition features over 10 new product lines including specifications, technical drawings and application highlights throughout.
The Keysight data acquisition solution uses signal resampling which provides on-board enhancement of the range analysis and offers a stable ADC signal sampling cadence. The solution focuses on the clock stability while acquiring the signal in order to avoid sampling cadence changes. This adverse effect on signal acquisition typically occurs when an external k-clock is used.
Dolomite Microfluidics has developed an innovative range of Micro Droplet Systems for automatic, seamless production of monodispersed droplets. Built around Dolomite’s pulseless pressure pumps, connectors and chips, Micro Droplet Systems benefit a wide range of applications, including compartmentalized chemistry and high-throughput experiments.
IONICON PTR-TOF systems are capable of measuring trace gas samples in real-time with a high mass resolving power. The new “fastGC” module adds an optional chemical separation step before the analysis. The module consists of a short GC column with an advanced heating concept for ultra-fast heating and equally fast cooling rates which makes this pre-separation step nearly real time.
AMSBIO has announced the availability of ultra-specific and extensively validated monoclonal antibodies under the UltraMAB brand. Screening of candidate antibodies against greater than 10,000 human proteins, using a High Density Protein Microarray Platform, has resulted in the identification of the most specific monoclonal antibodies (UltraMAB antibodies) available for cancer biomarkers and other important diagnostic targets.
Scientists have demonstrated a nanoscale memory technology for superconducting computing that could hasten the advent of an urgently awaited, low-energy alternative to power-hungry conventional data centers and supercomputers. In recent years, the stupendous and growing data demands of cloud computing, expanded Internet use, mobile device support and other applications have prompted the creation of large, centralized computing facilities.
HEMCO UniFlow PVC Acid Digestion Hoods are specifically designed and built for work with high volumes and concentrations of acids. With the interior including the worksurface of the fume hood fabricated one piece of PVC, the sash of clear polycarbonate and the exterior of the hood constructed of composite polyresin, the entire superstructure is totally non-metallic and extremely chemical resistant to meet the demands of acid digestion procedures.
Scientists from Yale Univ. have devised a way to ensure genetically modified organisms (GMOs) can be safely confined in the environment, overcoming a major obstacle to widespread use of GMOs in agriculture, energy production, waste management and medicine.
Nature packs away carbon in chalk, shells and rocks made by marine organisms that crystallize calcium carbonate. Now, research suggests that the soft, organic scaffolds in which such crystals form guide crystallization by soaking up the calcium like an "ion sponge". Understanding the process better may help researchers develop advanced materials for energy and environmental uses, such as for removing carbon dioxide from the atmosphere.
As nanomachine design rapidly advances, researchers are moving from wondering if the nanomachine works to how long it will work. This is an especially important question as there are so many potential applications, for instance, for medical uses, including drug delivery, early diagnosis, disease monitoring, instrumentation and surgery.
A new study by Univ. of Kentucky Markey Cancer Center researchers suggests that targeting a key enzyme and its associated metabolic programming may lead to novel drug development to treat lung cancer. Cancer cells undergo metabolic alterations to meet the increased energy demands that support their excess growth and survival.
