Estimation of Algae Growth Stage, Growth Rate, and Lipid Content

Applications include diesel fuel production, renewable energy, biofuels, and pharmaceuticals. Ames Research Center, Moffett Field, California This invention provides a method using light of different wavelengths to estimate freshwater and marine algae growth stage and algae growth rates as well as lipid content in standard media. Light absorption by the algae is measured for a specified light intensity in each of two or more narrow wavelength ranges, correcting for absorption in the medium without algae. The net light absorption is compared with a reference set of absorption values for the algae at different growth stages.

Isotopic Biomarkers for Rapid Assessment of Bone Mineral Balance in Biomedical Applications

Advanced isotope tracer techniques are explored. Lyndon B. Johnson Space Center, Houston, Texas Development of new treatments for metabolic bone disease, and evaluation of the effectiveness of existing therapies in individual patients, are severely hampered by the lack of any reliable tool for quickly measuring changes in bone mineral balance in response to treatment. A new tracerless calcium isotope biomarker of bone mineral balance fills this need. When properly applied, the calcium isotope biomarker reveals changes in bone mineral balance with unprecedented speed and detail, and has the potential to dramatically improve the treatment for diseases such as osteoporosis. A complementary strontium isotope biomarker provides, with equal rapidity, information on the speed of exchange of calcium between soft tissue and mineralized compartments.

Optically Modulated Miniature Magnetometer

This instrument may replace two separate instruments that are often needed together to study magnetic fields. Goddard Space Flight Center, Greenbelt, Maryland The optically modulated miniature magnetometer (OMMM) is intended to replace two separate instruments (each with their respective mass and power allotments) that are commonly needed together for scientific studies of magnetic fields — a triaxial fluxgate vector magnetometer and an optically pumped alkali vapor scalar magnetometer. For all vector instruments, the scalar data is necessary for calibrating the vector data.

How to Turn Your Engineers Into Product Design Superheroes

Today's innovative companies are built on the shoulders of the engineering teams responsible for designing products. Smart companies invest in tools that translate into better products. A modern Product Lifecycle Management (PLM) solution removes tedious admin responsibilities, streamlines the design environment, and empowers engineers to collaborate more efficiently with other departments. In short, PLM enables engineers to make the organization more profitable by allowing them to spend more time focused on the task they do best: designing innovative, world-class products. In this whitepaper, we focus on how PLM empowers engineers to spend more time on product design by optimizing their relationship with the different departments across the organization with which they must interact.

Simulations Reveal Material with Record-Setting Melting Point

Using advanced computers and a computational technique to simulate physical processes at the atomic level, researchers at Brown University have predicted that a material made from hafnium, nitrogen, and carbon would have the highest known melting point: 4,400 kelvins (7,460 degrees Fahrenheit), about two-thirds the temperature at the surface of the sun.

Molds for Medical Technology

The demand for productivity in the field of medical consumables is consistently growing at a rapid rate. The growth of the world’s population, expanding urbanization, aging societies, and increasing self-medication are contributing to this growing demand, despite manufacturers’ limited production space. Costs continue to rise, and manufacturers are increasingly looking at stack molds for their capability to double the output while reducing waste.
