Researchers from North Carolina State Univ. have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by these so-called “aberrating layers.” The researchers addressed this problem by designing customized metamaterial structures that take into account the acoustic properties of the aberrating layer and offsetting them.
Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as "active" sites. But scientists lack basic information about their function because the states thought to be critical to their chemical abilities cannot be experimentally observed.
Researchers from Oregon State Univ. and other institutions have developed a new biomarker called “SDMA” that can provide earlier identification of chronic kidney disease in cats, which is one of the leading causes of their death. A new test based on this biomarker, when commercialized, should help pet owners and their veterinarians watch for this problem through periodic checkups, and treat it with diet or other therapies.
A potential path to identify imperfections and improve the quality of nanomaterials for use in next-generation solar cells has emerged from a collaboration of Univ. of Oregon and industry researchers. To increase light-harvesting efficiency of solar cells beyond silicon's limit of about 29%, manufacturers have used layers of chemically synthesized semiconductor nanocrystals.
New findings by a Johns Hopkins Univ.-led team reveal long unknown details about carbon deep beneath the Earth’s surface and suggest ways this subterranean carbon might have influenced the history of life on the planet. The team also developed a new, related theory about how diamonds form in the Earth’s mantle.
Recent studies showing acid ceramidase (AC) to be upregulated in melanoma, lung and prostate cancers have made the enzyme a desired target for novel synthetic inhibitor compounds. In Angewandte Chemie, scientists with the Univ. of California, Irvine School of Medicine and the Italian Institute of Technology describe the very first class of AC inhibitors that may aid in the efficacy of chemotherapies.
A new discovery about the atomic structure of uranium dioxide will help scientists select the best computational model to simulate severe nuclear reactor accidents. Using the Advanced Photon Source, a team of researchers found that the atomic structure of uranium dioxide (UO2) changes significantly when it melts.
The R&D 100 Awards have a 50+ year history of recognizing excellence in innovation, earning the name the “Oscars of Invention." And at the annual event, the high rollers of the science and technology industry were honored on stage for their innovative, high-tech products and processes that are, or will, make a difference in our everyday lives.
Scientists at the world's largest smasher announced today that they have discovered two new subatomic particles never seen before that could widen our understanding of the universe. An experiment using the European Organization for Nuclear Research's Large Hadron Collider found the new particles, which were predicted to exist, and are both baryons made from three quarks bound together by a strong force.
Mark Hart, a scientist and engineer at Lawrence Livermore National Laboratory, has been awarded the 2015 Surety Transformation Initiative (STI) Award from the National Nuclear Security Administration’s Enhanced Surety Program. The STI award aims to stimulate and encourage the development of potentially transformational nuclear weapon surety technologies and explore innovative, preferably monumental shift solutions, to unmet surety needs.
Univ. of Utah engineers have developed a polarizing filter that allows in more light, leading the way for mobile device displays that last much longer on a single battery charge and cameras that can shoot in dim light. Polarizers are indispensable in digital photography and LCD displays, but they block enormous amounts of light, wasting energy and making it more difficult to photograph in low light.
Engineers have created a new way to use lidar technology to identify and classify landslides on a landscape scale, which may revolutionize the understanding of landslides in the U.S. and reveal them to be far more common and hazardous than often understood. The new, non-subjective technology can analyze and classify the landslide risk in an area of 50 or more square miles in about 30 mins.
Flexible electronic sensors based on paper have the potential to cut the price of a wide range of medical tools, from helpful robots to diagnostic tests. Scientists have now developed a fast, low-cost way of making these sensors by directly printing conductive ink on paper.
New research has found that one of the world's most prolific bacteria manages to afflict humans, animals and even plants by way of a mechanism not before seen in any infectious microorganism—a sense of touch. This unique ability helps make the bacteria Pseudomonas aeruginosa ubiquitous, but it also might leave these antibiotic-resistant organisms vulnerable to a new form of treatment.
A widely presumed problem of aging is that the brain becomes less flexible or plastic, and that learning may therefore become more difficult. A new study led by Brown Univ. researchers contradicts that notion with a finding that plasticity did occur in seniors who learned a task well, but it occurred in a different part of the brain than in younger people.
Argonne National Laboratory has announced a new intellectual property licensing agreement with AKHAN Semiconductor, continuing a productive public-private partnership that will bring diamond-based semiconductor technologies to market. The agreement gives AKHAN exclusive rights to a suite of breakthrough diamond-based semiconductor inventions developed by nanoscientist Ani Sumant of Argonne’s Center for Nanoscale Materials.
As hands come in left and right versions that are mirror images of each other, so do the amino acids and sugars within us. But unlike hands, only the left-oriented amino acids and the right-oriented sugars ever make into life as we know it. Scientists know the other varieties exist because when they synthesize these amino acids and sugars in a laboratory, roughly equal numbers of left- and right-facing arrangements form.
Now that car makers have demonstrated through hybrid vehicle success that consumers want less-polluting tailpipes, they are shifting even greener. In 2015, Toyota will roll out the first hydrogen fuel-cell car for personal use that emits only water. An article in Chemical & Engineering Newsexplains how hydrogen could supplant hybrid and electric car technology.
Inspired perhaps by Harry Potter's invisibility cloak, scientists have recently developed several ways to hide objects from view. The latest effort, developed at the Univ. of Rochester, not only overcomes some of the limitations of previous devices, but it uses inexpensive, readily available materials in a novel configuration.
A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space microphones. Researchers at Cardiff Univ. are trying to work out the possible sounds scientists might expect to hear when the ultra-sensitive LIGO and Virgo detectors are switched on in 2015.
Carpe diem…seize the day. This Latin phrase, coined by the Roman poet Horace in 23 BC, is used often to encourage us to take full advantage of the opportunities each day provides. In modern times with seemingly limitless amounts of data on any conceivable subject available at our fingertips, organizations globally are developing strategies to leverage this growing data volume to enhance business success.
Additive manufacturing, widely known as 3-D printing, offers many advantages over traditional manufacturing methods such as injection molding and machining, which limit a part’s geometry and size. By freeing manufacturers from these design constraints, additive manufacturing helps create complex parts that spark innovation and save companies time and money.
