Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. But scientists say they have developed a new software-based method that finds leaks even when they’re small, which could help prevent serious incidents and save money for customers and industry.
So long Silicon Valley. These days entrepreneurs and engineers are flocking to a place better known for surfing waves than the Web. Amid the palm trees and purple sunsets of the Southern California coastline, techies have built "Silicon Beach."
The AN/AAR-57 Common Missile Warning System (CMWS) helps protect Army aircraft from attack by shoulder-launched missiles and other threats. To keep this defensive system operating at maximum effectiveness, the Army periodically updates the software on the more than 1,000 AN/AAR-57 units in use around the world.
Though it garners few headlines, carbonic acid, the hydrated form of carbon dioxide, is critical to both the health of the atmosphere and the human body. However, because it exists for only a fraction of a second before changing into a mix of hydrogen and bicarbonate ions, carbonic acid has remained an enigma. A new study has yielded new information about carbonic acid with important implications for geological and biological concerns.
When studying extremely fast reactions in ultra-thin materials, two measurements are better than one. A new research tool invented by researchers at Lawrence Livermore National Laboratory (LLNL), Johns Hopkins Univ. and NIST captures information about both temperature and crystal structure during extremely fast reactions in thin-film materials.
Nature has developed a wide variety of methods for guiding particular cells, enzymes and molecules to specific structures inside the body: White blood cells can find their way to the site of an infection, while scar-forming cells migrate to the site of a wound. But finding ways of guiding artificial materials within the body has proven more difficult.
Action-packed science-fiction movies often feature colorful laser bolts. But what would a real laser missile look like during flight, if we could only make it out? How would it illuminate its surroundings? The answers lie in a film made by researchers in Poland who have captured the passage of an ultrashort laser pulse through the air.
Though neurobiologists have tried for half a century to better understand the brains of jumping spiders, no one has succeeded. The liquid in spiders’ bodies is pressurized, and they move with hydraulic pressure and muscles. But with a new technique using a tiny tungsten recording electrode, researchers have made recordings of neurons associated with visual perception inside the poppy seed-sized brain the spider.
While astronomers and geneticists embrace the concept, the culture of ecology still has a ways to go. Research by Michigan State Univ., published in the current issue of Bioscience, explores the paradox that although ecologists share findings via scientific journals, they do not share the data on which the studies are built.
Developing invisible implantable medical sensor arrays, a team of Univ. of Wisconsin-Madison engineers has overcome a major technological hurdle in researchers’ efforts to understand the brain. The team described its technology, which has applications in fields ranging from neuroscience to cardiac care and even contact lenses, in Nature Communications.
A startup company in Scotland is working to capitalize on the tons of waste produced by one of the country’s most valued industries and turn the dregs of whisky-making into fuel. Celtic Renewables, formed in 2011, has refined its process based on a century-old fermentation technique and is now taking the next step toward a commercial plant.
E+E Elektronik’s OILPORT 30 handheld meter accurately measures the water activity (aw) and temperature (T), and calculates the absolute water context x (ppm) of industrial oils. Users can store up to 10 sets of oil specific parameters in the handheld to be used for correct calculations of the water content in various oils.
Shimadzu Scientific Instruments has introduced its Open Solutions QuantAnalytics software package, an LC/MS/MS data tool for the pain management and clinical markets. The software increases the speed and efficiency of data processing and review by allowing users to highlight and review results that are of specific importance to clinicians.
Measuring oil content in wastes is nothing new to the petrochemical industry. Whether it’s produced water from onshore or offshore sites, effluents from refineriers or drill cuttings and drilling mud, limits on hydrocarbon levels need to be met. With the increase of hydraulic fracturing in the U.S., more public attention has been focused on the need for regulations and limits.
After 116 days of being subjected to extremely frigid temperatures like that in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA’s Goddard Space Flight Center. Operating a telescope powerful enough to reveal the first galaxies forming 13.5 billion years ago requires incredibly cold temperatures: about -387 F.
