Producing a model that looks like a human organ isn't enough for surgeons to practice on. Models also must mimic the feel of the real thing, and now that's possible with a 3D printer that can be tuned to produce varying degrees of elasticity.
A new energy system collects energy from the sun in the form of concentrated solar power and then stores that heat in such a way to sustain operation after the sun goes down. The CONTISOL concept, developed at the German Aerospace Center, heats two air-filled chambers: one that pipes hot air into a reactor to produce hydrogen and another that stores the hot air until evening, when it's released to continue the reaction.
A 4D camera developed at two California universities offers a 138-degree field of view that provides the data robots need to quickly calculate the distance to objects from a single image. It's a big improvement on the multiple images currently required to perform the same function.
Antimatter is touchy stuff that annihilates when it encounters ordinary matter and is usually confined to the place where it's created for research purposes. Scientists at CERN's Antiproton Decelerator in Geneva are planning to send a tiny amount of antimatter to another lab in Germany by creating billions of antiprotons to be stored in a vacuum and transported by an ordinary truck -- albeit a truck equipped with radiation shielding in the event of the worst happening.
Half of women who work in science, technology, engineering and math say they have experienced discrimination, including being paid less than men and being treated as if they are inept, according to a Pew Research Center study. Women who face the most discrimination include those with postgraduate degrees and those working in male-majority settings, the study finds.
The proposed Mountain Valley Pipeline in Virginia now has federal clearance to proceed. However, the natural gas pipeline builders still must obtain approval from the Virginia Department of Environmental Quality for anything more than tree removal, amid state concerns over erosion and sediment control.
The borough of Greencastle, Pa., has made plans for stream restoration, bioretention projects and street sweeping to curb the pollutants it's responsible for sending downstream into the Chesapeake Bay. It's anticipated the plan will cut sediment pollutant loads by 10%, yielding reductions of 3% and 5% in nitrogen and phosphorus, respectively.
Myersville, Md., will try to meet its MS4 obligations with a new ordinance that monitors property owners and penalizes those dumping pollutants into the city's storm system. However, the Myersville solution differs from state recommendations and will be reviewed.
The McKinley Channel flood control project in Alamogordo, N.M., lost federal funding under new regulations, but the Army Corps of Engineers says it has since pared projected construction costs. Now the redesigned project is only a few million dollars short, the Corps' Lt. Col. James Booth told city commissioners.
