Researchers have incorporated the lifecycle of phytoplankton and zooplankton— small, often microscopic animals at the bottom of the food chain— into a novel mechanistic model for assessing the global ocean carbon export.
A new report describes the National Nanotechnology Initiative vision and goals and the strategies by which these goals are to be achieved, including specific objectives within each of the goals.
The March issue of Laboratory Equipment details the extensive use of pure water in a laboratory environment. The cover story elaborates on the technologies and demand for higher performance, easier-to-use and more flexible lab water systems. The How To illustrates a method to avoid cross-contamination in milling applications, and the annual Purchasing Intent Study provides a finanical and scientific outlook on the future of lab equipment. Other articles detail mobile solutions in the healthcare industry and Raman excellence in geological applications.
Nanounity is now offering the Pemtron SEMART PS-250 scanning electron microscope (SEM) provides users with quick and easy operation, offering high performance at a reasonable price. With the power of the PS-230, the 250 allows users to work with larger samples up to 140 mm, while retaining 3 nm spatial resolution.
Datacolor has released CHROMACAL, a color calibration system for microscopy. Color in science is critical for evaluation, comparison, communications and decision-making; therefore, establishing and maintaining the integrity of color throughout the image capture and communication cycle is essential.
The I-3033 stage insert from ASI fits a standard 110 x 160 mm opening found in most automated XY stages. The unit offers an autoclavable stainless steel dish chamber with replaceable 25 mm glass coverslip bottoms in both 20 and 25 mm diameter sizes.
EDAX’s Octane TEM (transmission electron microscope) Series offers modules sized from 30 to 100 mm2, and provides solid angles up to 1.1 steradian. Built with EDAX Smart detector design, the detectors allow optimal geometry inside the TEM column and maximize data collection.
FEI’s Tecnai Femto ultrafast electron microscope (UEM) enables scientists to explore ultrafast events and processes that occur at the atomic and molecular spatial scale over time spans measured in femtoseconds (10-15 seconds). These include such fundamental processes as the absorption of light energy and its transformation into heat or mechanical changes (photoactuation) and the crystallization or recrystallization of materials—including large biological molecules for structural analysis.
Whatever the reasons, this winter’s pattern has resulted in two months (as this is written) of cold weather 20 to 40 degrees below the normal averages in the entire region from the Mississippi River to the Atlantic Ocean, affecting nearly 200 million Americans. And the rains seen in the UK surpassed anything seen in that area since they started keeping records several hundred years ago.
Increasing analytical instrumentation capabilities are expected to drive the demand for higher performance, easier-to-use and more flexible lab water systems.
Because of California's lingering drought, millions of young California salmon could soon be migrating to the ocean via freeways instead of the Sacramento River.
Mobile solutions are revolutionizing healthcare, bringing point-of-care and personalized medicine to the forefront of the industry.
Raman spectroscopy can accurately identify various mineral components in a geological sample, as well as provide detailed structural information.
A Japanese government-funded laboratory says that it is considering retracting a research paper describing a simple way of turning ordinary cells from mice into stem cells.
The malaise in research laboratory spending that enveloped 2013 looks to be replaced by solid, albeit modest, growth in 2014.
