Sweeping air devices for greener planes

October 21, 2014 8:36 am | News | Comments

The large amount of jet fuel required to fly an airplane from point A to point B can have negative impacts on the environment and a traveler's wallet. With funding from NASA and the Boeing Company, engineers from Caltech and the Univ. of Arizona have developed a device that lets planes fly with much smaller tails, reducing the planes' overall size and weight, thus increasing fuel efficiency.

Starfish shell-mimicking crystals could advance 3-D printing pills

October 21, 2014 8:19 am | by Nicole Casal Moore, Univ. of Michigan | News | Comments

In a design that mimics a hard-to-duplicate texture of starfish shells, Univ. of Michigan engineers have made rounded crystals that have no facets. The team calls the crystals "nanolobes". The nanolobes' shape and the way they're made have promising applications. The geometry could potentially be useful to guide light in advanced LEDs, solar cells and non-reflective surfaces.

High blood-sugar levels may harden heart valves

October 21, 2014 8:05 am | by Mike Williams, Rice Univ. | News | Comments

Rice Univ. bioengineers have found new evidence of a possible link between diabetes and the hardening of heart valves. A Rice laboratory, in collaboration with the Univ. of Texas Health Science Center at Houston Medical School, discovered that the interstitial cells that turn raw materials into heart valves need just the right amount of nutrients for proper metabolic function.

Getting the salt out

October 21, 2014 7:54 am | by David L. Chandler, MIT News Office | News | Comments

The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that’s much saltier than seawater, after leaching salts from rocks deep below the surface. Now researchers at Massachusetts Institute of Technology and in Saudi Arabia say they have found an economical solution for removing the salt from this water.

World record in data transmission with smart circuits

October 21, 2014 7:39 am | News | Comments

Fewer cords, smaller antennas and quicker video transmission. This may be the result of a new type of microwave circuit that was designed at Chalmers Univ. of Technology. The research team behind the circuits currently holds an attention-grabbing record: 40 Gbps, about twice as fast as the previous record at 140 GHz. The results will be presented at a conference this week in San Diego.

CDC releases revised Ebola gear guidelines

October 20, 2014 11:29 pm | by Mike Stobbe - Associated Press - Associated Press | News | Comments

Federal health officials on Monday issued new guidelines to promote head-to-toe protection for health workers treating Ebola patients. Officials have been scrambling to come up with new advice for protective gear since two Dallas nurses became infected while caring for the first person diagnosed with the virus in the U.S.

When emotions control objects

October 20, 2014 11:51 am | by Cécilia Carron, EPFL | Videos | Comments

Sensors developed by SmartCardia, a spin-off from EPFL in Switzerland, use various biological vital signs to transmit data to a host of everyday objects. This data, which includes heart rate, respiration activity, skin conductivity and physical exertion, can be used dim a light, control immersive playing on a computer, and track yoga exercises in real time.

Study: Odors, chemicals above health standards caused by “green building” plumbing

October 20, 2014 11:27 am | by Emil Venere, Purdue Univ. | News | Comments

Several types of plastic pipes in eco-friendly green buildings in the U.S. have been found to leach chemicals into drinking water that can cause odors and sometimes exist at levels that may exceed health standards. Purdue Univ. engineering professor Andrew Whelton will detail these findings during the 2014 U.S. Green Building Council’s Greenbuild International Conference & Exposition on Oct. 24 in New Orleans.

Atomic trigger shatters mystery of how glass deforms

October 20, 2014 11:04 am | News | Comments

Research at Oak Ridge National Laboratory has cracked one mystery of glass to shed light on the mechanism that triggers its deformation before shattering. The study improves understanding of glassy deformation and may accelerate broader application of metallic glass, a moldable, wear-resistant, magnetically exploitable material that is thrice as strong as the mightiest steel and ten times as springy.

Multispectral Imaging Camera

October 20, 2014 10:40 am | Product Releases | Comments

Teledyne DALSA has introduced its Piranha4 2k quadlinear line scan camera featuring red, green and blue (RGB) outputs plus a near-infrared (NIR) channel for multispectral imaging. The quadlinear Piranha4 is built around Teledyne DALSA’s advanced CMOS image sensor design. Wafer-level dichroic filters enable spectrally independent RGB and NIR outputs, enhancing detection capability for a wide range of machine vision applications, including print, bank note inspection, electronics manufacturing, food and material sorting.

Imaging electric charge propagating along microbial nanowires

October 20, 2014 10:37 am | News | Comments

The claim by microbiologist Derek Lovley and colleagues at the Univ. of Massachusetts Amherst that the microbe Geobacter produces tiny electrical wires, called microbial nanowires, has been mired in controversy for a decade, but the researchers say a new collaborative study provides stronger evidence than ever to support their claims. Their finding involves a new imaging technique, electrostatic force microscopy.

Syringe Drive for Precise Liquid Handling

October 20, 2014 10:31 am | Product Releases | Comments

Hamilton’s Laboratory and Sensors Div. has introduced the Hamilton Precision Syringe Drive 6 (PSD/6); a compact, full-height pump for precision dispensing of small to large volumes. The Hamilton PSD/6 is the newest full-height syringe pump to join the Hamilton PSD family, and performs all standard liquid handling functions including dispensing, serial dispensing and diluting.

EU seeking to create $1.27 billion Ebola fund

Solutions in Search of Problems: Spectroscopy Takes Flight

October 20, 2014 10:07 am | by Yvette Mattley, PhD, Senior Applications Specialist and Rob Morris, Marketing Operations Manager, Ocean Optics | Ocean Optics | Articles | Comments

Spectral sensing is so pervasive that most take it for granted. Even miniature spectrometers have been embraced by late adopters. Yet, spectroscopy has moved beyond routine laboratory and test measurements to take on ever-more sophisticated applications. In this article we explore how familiar spectral sensing technologies—and new ways to exploit them—are today addressing a wider range of measurement problems than ever.
