Perfect Acoustics in Greek Theaters: Just a Myth
Ancient Greek theaters — at least three famous ones — do not live up to their claims of perfect acoustics.
Researchers Use A SPIM System with Two Lenses to View High Quality Biospecimens
Researchers from the National Institutes of Health and the University of Chicago improved the speed, resolution and light efficiency of an optical microscope by switching from a conventional glass coverslip to a reflective, mirrored coverslip and applying new computer algorithms to process the resulting data.
Artificial Sweetners in Groundwater Signal Contamination from Septic Systems
Researchers have determined that the presence of artificial sweeteners in rural groundwater is evidence of local septic system wastewater contamination.
New Ultrafast Scan Rate Miniature Spectrometer for High Speed Applications!
The Ocean FX® from Ocean Optics is a versatile spectrometer with acquisition speed up to 4,500 scans per second, onboard averaging of up to 5,000 spectra for improved signal to ratio (SNR) and minimal data transfer time. Ocean FX is an excellent choice for high-speed process applications, measurement of fast events, and reaction monitoring!
Satellite Measures Space-Based Indicators of Surface Ozone Trends
The Dutch-Finnish Ozone Monitoring Instrument aboard NASA's Aura satellite is monitoring concentrations of formaldehyde and nitrogen dioxide -- both agents in ozone formation.
Moving Bus Stop Locations Could Cut Riders' Pollution Exposure
Consequently, the research team believes that exposure to pollutants would be dramatically reduced by moving bus and light rail stops 120 feet from high-traffic intersections.
Watch: Beating Cancer at its Own Game
By reprogramming the genetic material of cancer cells, researchers have found a way to disable their most impressive ability: that of adapting and surviving.
Watch: Mechanical Engineers Design the Perfect Yo-Yo
The challenge of designing the perfect yo-yo proves to be fertile ground for Georgia Tech students learning about mechanical design and computer-aided manufacturing.
Decorative Drinking Glasses Can Contain Harmful Levels of Lead, Cadmium
Using portable x-ray fluorescence (XRF) spectrometry to analyze different drinking glass types such as tumblers, beer and wine glasses, and jars, researchers determined that lead levels on some of the glassware exceeded limits — in some cases by as much as 1,000 times.
10 Percent of Meat Dishes Sold in Mexico Contain Horse Meat, According to Study
According to a study conducted by researchers from the School of Veterinary Medicine at Mexico's National Autonomous University, nearly 10 percent of the meat sold in five Mexican cities contained horse DNA.
Optical Device May Lead to Cleaner Air and Skies
A new optical device at Sandia National Laboratories that helps image pollutants in combusting fuel sprays might lead to clearer skies in the future.
Study Looks at Consumer Feelings About Lab-grown Meat
Although complex to produce, researchers believe that developing actual meat that doesn’t require raising and killing animals might be a future solution to issues surrounding meat consumption.
Asteroid Wipes Out Dinosaurs But Delivers Cancer Destroyer
Iridium is rare on our planet but abundant in meteoroids, and can be manipulated to kill cancer without harming healthy cells.
'World's Shortest Laser Pulse' Provides Unprecedented Atomic Access
By creating a laser pulse on the time scale of electrons, researchers can now observe — and control — chemical reactions with an unprecedented level of resolution.
Medical Diagnostics Inspire NASA’s Extraterrestrial Sample Triage Plans
Leave it to engineers to apply a principle of medical diagnostics to the “triage” of extraterrestrial rocks and other samples before they are shipped to Earth.
Pan-and-Tilt Pipe Camera with Flexible Push Cable
Extremely durable pan-and-tilt pipe camera that produces bright, crisp and colorful images facilitates inspection and measurement of pipes and ductwork in plumbing, HVAC and well and sewage tank applications.
Newly Developed Filters Use Nanoparticles to Prevent Slime Buildup
Researchers at the University of Pennsylvania’s School of Engineering and Applied Science have a new way of making membranes that could address this problem. Their method allows them to add in a host of new abilities via functional nanoparticles that adhere to the surface of the mesh.
Safer Water Using UV Light
Inspired by an experience involving contaminated well water in her rural Kentucky hometown, Ph.D. student Natalie Hull is exploring the different wavelengths of ultraviolet radiation needed to kill dangerous drinking water pathogens.
Research Could Save Money and Reform Nuclear Waste Reprocessing
Rutgers-New Brunswick scientists have been seeking a better way to capture radioactive iodides in spent nuclear reactor fuel. They have developed an extremely efficient “molecular trap” that can be recycled and reused.
Video Gaming Technology Inspires Advance in Medical Imaging
A microchip like the one used in a Wii gaming system is being used to leverage inexpensive, portable ultrasound technology into invaluable 3D imaging.
