Should CO2 emissions be regulated?

This week’s question concerns the EPA’s regulation of greenhouse gas emissions. Last Thursday, the US Senate failed to pass legislation that would have prevented the Environmental Protection Agency (EPA) from regulating CO2 emissions from large factories, electric power companies, and automobiles.

What do you think? Should CO2 emissions be regulated? Yes or no?

Monitoring Carbon Dioxide Underground

A technique originally applied to monitor the flow of contaminants into shallow groundwater supplies has been repurposed by Lawrence Livermore National Laboratory researchers to monitor carbon dioxide pumped deep underground for storage.

Scientists Use Nanoscale Architecture to Make Efficient Solar Cell

A thin film solar cell must be thick enough to collect a sufficient amount of light, yet it needs to be thin enough to extract current. Boston College physicists found a way to resolve the "thick & thin" challenge through a nanoscale solar architecture based on the coaxial cable.

Should Google be liable for "bad" directions that lead to injury?

This week's question concerns a recent news item about how a Utah woman injured by a motorist while following a Google Maps route has filed a lawsuit claiming Google supplied unsafe directions (the motorist is also named in the lawsuit). The woman used her phone to download directions from one end of Park City, UT, to the other. Google Maps led her to a four-lane boulevard without sidewalks that was "not reasonably safe for pedestrians," according to the lawsuit. The woman believed she could reach a sidewalk on the other side of the boulevard and therefore tried to cross. A car struck her before she even reached the median. The woman received multiple bone fractures that required six weeks of rehabilitation.

What do you think? Should Google be liable for "bad" directions that lead to injury? Yes or no?

Formula for the Removal and Remediation of Polychlorinated Biphenyls in Painted Structures

An activated metal treatment system (AMTS) removes and destroys polychlorinated biphenyls (PCBs) found in painted structures or within the binding or caulking material on structures. It may be applied using a “paint-on and wipe-off” process that leaves the structure PCB-free and virtually unaltered in physical form.

Low-Noise Current Controller Increases Detection of Trace Gases

A low-noise current controller developed at DOE's Pacific Northwest National Laboratory was recently licensed to Wavelength Electronics Inc. (Bozeman, MT). The device delivers stable and reliable power to the lasers used in gas sensors, for use in analyzing trace atmospheric gases.

Kaman Precision Products/ Measuring, Middletown, CT, has introduced the KD-2446, a high-precision proximity sensor system that offers RoHS and CE compliance in a compact DIN package. With a 10-KHz analog output and threshold-adjustable 3.3-KHz switched output, the sensor is designed for high-speed automated manufacturing and process control applications. The sensor provides 0.008%FS resolution and 0.56%FS switch point hysteresis. Applications include displacement, vibration, sorting, and event capture. The sensor uses inductive eddy current technology that measures without touching the target, and works with both ferrous and non-ferrous targets. The system consists of two sub-assemblies: the sensor with integral cable, and the signal conditioning or electronics module. Input voltage is variable from 12 to 24 V DC, and gain is adjustable for up to 22 V output (with 24 Vdc input). The system comes standard with one of two production sensor configurations: the 9C or the 5CM. Both rugged sensors are rated for continuous operation up to 400 °F.

NASA Engineers Improve GPS Signal Reception

GPS (Global Positioning System) navigational devices are as ubiquitous as cell phones, freely used by commercial and government users to determine location, time, and velocity. These tools, however, are only as good as the signals they receive. NASA engineers from Goddard Space Flight Center in Greenbelt, MD, have found a way to improve the reception of those signals.

Software Improves Access to NASA Earth Models

Frontier Grid Platform for distributed computing
Parabon Computation
Reston, VA

Access to complex climate modeling and simulation models from NASA’s Earth-observing satellites will be easier after development of a Web-based system from Parabon Computation. The company is working with NASA’s Goddard Space Flight Center (Greenbelt, MD) to help scientists access climate models. The models would be hosted as a Web service so users can access and run them in a Web browser, without the use of a local copy of the application.

Custom Assembly Helps Create Medical-Grade Saline in Space

BioConnect® bag and tubing assemblies
Cole-Parmer Instrument
Vernon Hills, IL

BioConnect custom bag and tubing assemblies supplied the materials and services to catalyze the production of a prototype for the Intravenous Fluid Generation (IV Gen) technology demonstration on the International Space Station. Funded through NASA’s Human Research Program, a team from NASA’s Glenn Research Center (Cleveland, OH) and ZIN Technologies (Cleveland) seeks to produce medical-grade saline solution in a zero-gravity environment. If successful, the process solves the challenge of packing IV solution that expires during the shuttle cycle, and alleviates mass and volume storage constraints.
