Air pollution regulations issued by the U.S. Environmental Protection Agency are estimated to save thousands of lives annually. A new study by researchers at Indiana Univ. says these estimates are more uncertain than commonly believed. Researchers analyzed the costs and expected lifesavings of nine regulations issued between 2011 and 2013. The bulk of these regulations require national emissions standards for hazardous air pollutants.
Polymer solar cells are a hot area of research due to both their strong future potential and the significant challenges they pose. It is believed that thanks to lower production costs, they could become a viable alternative to conventional solar cells with silicon substrates when they achieve a power conversion efficiency of between 10 and 15%.
Reporting on their study with lab-grown human cells, researchers at The Johns Hopkins Univ. and the Univ. of Maryland say that blocking a second blood vessel growth protein, along with one that is already well-known, could offer a new way to treat and prevent a blinding eye disease caused by diabetes.
Scientists at Brookhaven National Laboratory have just taken a big step toward the goal of engineering dynamic nanomaterials whose structure and associated properties can be switched on demand. In a paper appearing in Nature Materials, they describe a way to selectively rearrange the nanoparticles in 3-D arrays to produce different configurations, or phases, from the same nanocomponents.
Scientists at Argonne National Laboratory have found a way to use tiny diamonds and graphene to give friction the slip, creating a new material combination that demonstrates the rare phenomenon of “superlubricity.” The five-person Argonne team combined diamond nanoparticles, small patches of graphene and a diamond-like carbon material to create superlubricity, a highly-desirable property in which friction drops to near zero.
Rice Univ. researchers have developed a method to detect rare DNA mutations with an approach hundreds of times more powerful than current methods. The technique allows the researchers to find a figurative needle in a haystack that’s smaller than any needle.
Global warming will bring much more sneezing and wheezing to Europe by mid-century, a new study says. Ragweed pollen levels are likely to quadruple for much of Europe because warmer temperatures will allow the plants to take root more, and carbon dioxide will make them grow more. Other factors not related to man-made climate change will also contribute.
Lofty living may make babies vulnerable to sudden infant death syndrome, according to a Colorado study that found higher risks above 8,000 ft (2,400 m). While the research shows that the SIDS rate in Colorado's tall mountains is very low, it's still two times greater than in the Denver area and other regions where the altitude is less than 6,000 ft (1,800 m). The results echo earlier research done in Austria's Alps.
The world’s first reference material to help ensure laboratories accurately “map” DNA for genetic testing, medical diagnoses and future customized drug therapies is now available from NIST. The new reference material, NIST RM 8398, is a “measuring stick” for the human genome, the coded blueprints of a person’s genetic traits.
It looks like a Slinky suspended in motion. Yet this photonics advancement, called a metamaterial hyperlens, doesn’t climb down stairs. Instead, it improves our ability to see tiny objects. The hyperlens may someday help detect some of the most lethal forms of cancer.
Univ. of California, Berkeley researchers have developed algorithms that enable robots to learn motor tasks through trial and error using a process that more closely approximates the way humans learn, marking a major milestone in the field of artificial intelligence. They demonstrated their technique, a type of reinforcement learning, by having a robot complete various tasks without pre-programmed details about its surroundings.
Omega Engineering’s new series of CE-compliant ultrasonic leak detectors features an ultrasonic sound range of 20 to 100 kHz. The HHLT-1 series is suitable for pressure and vacuum system leak detection, exhaust system, tanks and pipe leak testing, as well as steam trap inspection and gas leaks in general.
Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner.
Data centers are one of the largest and fastest-growing consumers of electricity in the U.S. The industry has been shifting from open-air cooling of these facilities to increasingly complex systems that segregate hot air from cold air. When it comes to cost savings, there are definite advantages to the aisle containment systems, which have been estimated to save 30% of cooling energy.
The efficiency of synchrotron light sources is heavily dependent on the vacuum quality within the beam lines, small mass spectrometers (RGAs) are routinely utilized to provide real-time vacuum monitoring for confirmation of contaminant status, and the associated radiation level is a potential issue. Hiden Analytical manufactures quadrupole mass spectrometers with radiation hardened electronics having operation established at radiation levels in the regime of 1x10E7 Rads per annum.
