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.
A recent review of retractions in medical and biological peer-reviewed journals finds the percentage of studies withdrawn because of fraud or suspected fraud has jumped substantially since the mid-1970s. In 1976, there were fewer than 10 fraud retractions for every 1 million studies published, compared with 96 retractions per million in 2007.
As data centers continue to come under scrutiny for the amount of energy they use, researchers at University of Toronto Scarborough have a suggestion: turn the air conditioning down. Their latest research suggests that turning up the temperature could save energy with little or no increased risk of equipment failure.
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.
From Napster to iTunes to Pandora, the methods by which the public can obtain and share music have rapidly progressed. Future groundbreaking innovations may need to wait, though, as the next generation of technology is being stymied by the very copyright laws that seek to protect the industry, says Rutgers-Camden University professor Michael Carrier in a new article for a law journal..
According to data from a 2008 Business R&D and Innovation Survey by the National Science Foundation, businesses perform the lion's share of their R&D activity in just a small number of geographic areas, particularly the San Jose-San Francisco-Oakland area and the New York-Newark-Bridgeport area.
A neutron detector developed for studies focused on life science, drug discovery, and materials technology has been licensed by PartTec Ltd. The Indiana-based manufacturer of radiation detection technologies is moving the technology developed at Oak Ridge National Laboratory toward the commercial marketplace.
Founded in 2002, the Statistical and Applied Mathematical Sciences Institute (SAMSI) is one of eight mathematical institutes funded by the NSF’s Division of Mathematical Sciences, and the only one that focuses on statistics and applied mathematics. SAMSI’s funding has recently been renewed by the National Science Foundation (NSF) for five years.
NASA recently picked three aerospace companies to build small rocketships to take astronauts to the International Space Station. This is the third phase of NASA's efforts to get private space companies to take over the job of the now-retired space shuttle. The companies will share more than $1.1 billion. Two of the ships are capsules like in the Apollo era and the third is closer in design to the space shuttle.
In 2010, Sandia National Laboratories researcher Jeff Tsao and Harry Saunders of The Breakthrough Institute in Oakland, Calif., predicted that light-emitting diodes would have a similar improvement in productivity—but not less energy use—that occurred upon the introduction of the Edison light bulb. Now, they have reprised their report to emphasize conclusions they say were misinterpreted by the media.
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.
According to a recent National Science Foundation report, the amount of R&D funding that passed through universities to others for collaborative projects during fiscal years 2000 to 2009 grew more rapidly than overall academic R&D expenditures. Federal initiatives and technological advances are thought to be contributing factors to this trend.
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.
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.
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.
More and more companies are turning to simplified procedures to help tackle complex product design tasks. At the Massachusetts Institute of Technology, work on Design Structure Matrix analysis is helping heavyweight companies improve their products, production lines and organizations by transforming product design into a productive routine.
Do you have what it takes to be an ethical hacker? Can you step into the shoes of a professional paid to outsmart supposedly locked-down systems? "Control-Alt-Hack", a new card game developed by University of Washington computer scientists, gives teenage and young-adult players a taste of what it means to be a computer-security professional defending against an ever-expanding range of digital threats.
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.
Nuclear weapons testing may at first glance appear to have little connection with climate change research. But key Cold War research laboratories and the science used to track radioactivity and model nuclear bomb blasts have today been repurposed by climate scientists.
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?
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.
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.
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.
In a speech Wednesday, ExxonMobil CEO Rex Tillerson said fears about climate change, drilling, and energy dependence are overblown. He acknowledged that burning of fossil fuels is warming the planet, but said society will be able to adapt and dependence on other nations for oil is not a concern as long as access to supply is certain.
South Africa and Australia had competed fiercely against each other for the Square Kilometer Array telescope project, which will become the world’s biggest instrument when built. Recently, the consortium overseeing the effort decided to award it to both countries, with South Africa getting the lion’s share of the radio dishes.
