Restricting nuclear power has little effect on the cost of climate policies

October 2, 2012 9:03 am | News | Comments

Applying a global energy-economy computer simulation that fully captures the competition between alternative power supply technologies, a team of scientists from the Potsdam Institute for Climate Impact Research and the University of Dayton, Ohio, analyzed trade-offs between nuclear and climate policies. They found that incremental costs due to policy options restricting the use of nuclear power do not significantly increase the cost of even stringent greenhouse-gas emissions reductions.

Researchers make call for specialty metals recycling

September 24, 2012 2:56 pm | News | Comments

According to recent paper published by Yale University scientists, an international policy is needed for recycling scarce specialty metals that are critical in the production of consumer goods. Specialty metals account for more than 30 of the 60 metals on the periodic table, and their rapidly accelerating usage in many industries makes the complete lack of recycling a concern.

Study: Tradeoffs needed in battling urban heat island effects

September 11, 2012 4:15 am | News | Comments

A team of researchers from Arizona State University have found that warming resulting from megapolitan expansion is seasonally dependent, with greatest warming occurring during summer and least during winter. Painting the roofs of buildings white can combat this effect, but not without consequences for the region’s hydroclimate.

EPA releases nanomaterial case study regarding nanoscale silver

August 6, 2012 6:05 am | News | Comments

The U.S. Environmental Protection Agency has completed and published a comprehensive environmental assessment (CEA) framework study of engineered nanoscale silver, specifically with regard to its behavior in disinfectant sprays. Though not a formal assessment, many factors such as product life cycle, environmental transport and fate, exposure-dose in receptors, and potential impacts in these receptors are covered in the report.

DOE grant goes to lithium-ion battery development

August 6, 2012 5:43 am | News | Comments

Washington University in St. Louis recently landed a $2 million U.S. Dept. of Energy grant with $1.2 million in matching funds from the university to design a battery management system for lithium-ion batteries that will guarantee their longevity, safety and performance.

NSF reports on state-by-state R & D activities

August 3, 2012 5:20 am | News | Comments

A recent report released by the National Science Foundation (NSF) found state government agency expenditures for research and development totaled $1.2 billion in fiscal year 2009, a 7% increase over the fiscal 2007 total of $1.1 billion. The survey marked the first time NSF asked state agencies to classify their R&D according to specific categories.

Gas drilling research suffers from lack of funding

August 2, 2012 10:28 am | by Kevin Begos, Associated Press | News | Comments

Is gas drilling ruining the air, polluting water and making people sick? The evidence is sketchy and inconclusive, but a lack of serious funding is delaying efforts to resolve those pressing questions and creating a vacuum that could lead to a crush of lawsuits, some experts say.

NREL study shows renewable energy potential in every state

August 2, 2012 5:35 am | News | Comments

A new study of renewable energy’s technical potential finds that every state in the nation has the space and resource to generate clean energy. The National Renewable Energy Laboratory produced the study, which looks at available renewable resources in each state and establishes an upper-boundary estimate of development potential.

23andMe seeks FDA approval for personal DNA test

August 1, 2012 3:24 am | by Matthew Perrone, AP Health Writer | News | Comments

For years, the Silicon Valley company has resisted government regulation, arguing that it simply provides consumers with information, not a medical service. Genetic test maker 23andMe, however, is now asking the Food and Drug Administration to approve its personalized DNA test in a move that, if successful, could boost acceptance of technology that is viewed skeptically by leading scientists who question its usefulness.

Federal panel supports Kansas biosecurity lab project

July 15, 2012 2:20 pm | by John Milburn, Associated Press | News | Comments

A government-backed committee of the National Research Council issued a report Friday saying the United States would have adequate biosecurity protections even if plans for a proposed $1.14 billion lab in Kansas are scaled back.

Can fracking pollute water? Study tries to answer

July 13, 2012 3:51 am | by Kevin Begos, Associated Press | News | Comments

A drilling company in southwestern Pennsylvania has given researchers at National Energy Technology Laboratory access to a commercial drilling site, a move that may provide some of the first solid answers to a controversial question: Can gas drilling fluids migrate and pose a threat to drinking water?

Study: Natural gas “much-needed tool” in climate battle

July 10, 2012 2:54 pm | News | Comments

The conclusion of a new study by Cornell University Professor Lawrence M. Cathles shows that, no matter the timeframe considered, substituting natural gas energy for all coal and some oil production provides about 40% of the global warming benefit that a complete switch to low-carbon sources would deliver. And, it would be a far quicker option than going to sources like nuclear or solar.

DARPA creates program to promote robotic actuation efficiency

July 5, 2012 7:41 am | News | Comments

Humans and animals have evolved to consume energy very efficiently for movement. If robotic actuation can be made to approach the efficiency of human and animal actuation, the range of practical robotic applications will greatly increase. To help this progression, DARPA has created the M3 Actuation program with the goal of achieving a 2,000% increase in the efficiency of power transmission and application.

FDA panel sees little use for metal-on-metal hips

July 2, 2012 6:38 am | by Matthew Perrone, AP Health Writer | News | Comments

Government health experts said Thursday there are few reasons to continue using metal-on-metal hip implants, amid growing evidence that the devices can break down early and expose patients to dangerous metallic particles. The devices were originally marketed as a longer-lasting alternative to older ceramic and plastic models. But recent data from the U.K. and other foreign countries suggests they are more likely to deteriorate.

China on Wednesday defended its export curbs on rare earths used in high-tech products as an environmental measure and rejected a World Trade Organization challenge by the United States, Europe, and Japan.

Study: U.S. must encourage development of Canadian oil sands

June 12, 2012 5:03 am | News | Comments

To successfully reduce the United States' dependence on fuels from outside North America, the government must pursue policies that foster the diversion of Canadian oil sands crude to U.S. Gulf Coast refineries, according to a new study by Rice University's Baker Institute for Public Policy.

Commercial space race gets crowded behind SpaceX

May 24, 2012 12:24 pm | by Seth Borenstein, AP Science Writer | News | Comments

NASA has hired Space Exploration Technologies Corp. to deliver cargo to the International Space Station, but will eventually add astronauts. And the space agency is hiring other companies, too. Several firms—at least eight—think they can make money in space and are close enough to Musk's company to practically surf in his spaceship's rocket-fueled wake.

A new look at prolonged radiation exposure

May 15, 2012 3:42 am | by Anne Trafton, MIT News Office | News | Comments

A new study from Massachusetts Institute of Technology scientists suggests that the guidelines governments use to determine when to evacuate people following a nuclear accident may be too conservative. The study found that when mice were exposed to radiation doses about 400 times greater than background levels for five weeks, no DNA damage could be detected.

First of two papers on lab-made bird flu published

May 3, 2012 5:09 am | by Malcolm Ritter, AP Science Writer | News | Comments

Four months ago the U.S. government sought to block publication of two studies about how scientists created an easily spread form of bird flu. Now a revised version of one paper is seeing the light of day with the government's blessing. The second paper, which is more controversial because it involves what appears to be a more dangerous virus, is expected to be published later.
