Director Rodney Ruoff's research group from the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS) at the Ulsan National Institute of Science and Technology (UNIST) has reported a truly single layer (i.e., adlayer-free) large area graphene film on large area copper foils. This might seem like the latest in a series of seemingly similar declarations on single layer graphene. However, this achievement differs from other thousands of previous publications in that none of them had described truly single layer graphene over large area.
Variants in the gene ARMC5 may be associated with high blood pressure among blacks, according to a National Institutes of Health study led by researchers at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). The study team identified 17 variants in the ARMC5 gene that were associated with high blood pressure by analyzing genetic research databases that include those of African descent. The study is published in the July 3, 2019, issue of the Journal of the American Heart Association.
Poorer overall diet quality was linked with an increased risk of becoming frail in a study of U.S. community-dwelling older adults, published in the Journal of the American Geriatric Society. The quality of the overall diet appeared to be more important than protein intake for a lower risk of frailty.
A tsunami holds its wave shape over very long distances across the ocean, retaining its power and 'information' far from its source.
In communications science, retaining information in an optic fibre that spans continents is vital. Ideally, this requires the manipulation of light in silicon chips at the source and reception end of the fibre without altering the wave shape of the photonic packet of information. Doing so has eluded scientists until now.
Researchers have conquered the monumental task of manufacturing scalable nanoprobe arrays small enough to record the inner workings of human cardiac cells and primary neurons.
Specimens kept in the collection of the Institute of Beneficial Insects at the Fujian Agriculture and Forestry University (FAFU, China) revealed the existence of two previously unknown species of endoparasitoid wasps. Originally collected in 2013, the insects are known to inhabit prairies and bushes at above 3,400 m, which is quite an unusual altitude for this group of wasps.
An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.
Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus electricity from wind power plants. However, the platinum used in fuel cells is rare and extremely expensive, which has been a limiting factor in applications up to now.
Scientists at the University of Birmingham have shed fresh light on the mechanism used by certain types of bacteria to protect themselves against attack.
Gram negative bacteria can cause diseases such as pneumonia, cholera, typhoid fever and E. coli infections, as well as many hospital acquired infections. They are increasingly resistant to antibiotics - and this is partly because of the way they are built.
Named after a Celtic goddess of the Sun, SULIS is a UK-led solar science mission, designed to answer fundamental questions about the physics of solar storms. The mission consists of a cluster of small satellites and will carefully monitor solar storms using state-of-the-art UK technology, as well as demonstrating new technologies in space. Lead Investigator on the project, Dr Eamon Scullion of Northumbria University, will reveal plans for the mission on Wednesday, 3 July at the Royal Astronomical Society's National Astronomy Meeting in Lancaster.
In a major collaborative effort, researchers at the Lewis Katz School of Medicine at Temple University and the University of Nebraska Medical Center (UNMC) have for the first time eliminated replication-competent HIV-1 DNA - the virus responsible for AIDS - from the genomes of living animals. The study, reported online July 2 in the journal Nature Communications, marks a critical step toward the development of a possible cure for human HIV infection.
Techniques developed by astronomers could help in the fight against breast and skin cancer. Charlie Jeynes at the University of Exeter will present his and Prof Tim Harries team's work today (3 July) at the RAS National Astronomy Meeting (NAM 2019) at the University of Lancaster.
A large part of astronomy depends on the detection and analysis of light. For example, scientists study the light scattered, absorbed and re-emitted in clouds of gas and dust, obtaining information on their interior.
Scientists from the University of Bristol and the Technical University of Denmark have found a promising new way to build the next generation of quantum simulators combining light and silicon micro-chips.
In the roadmap to develop quantum machines able to compete and overcome classical supercomputers in solving specific problems, the scientific community is facing two main technological challenges.
For centuries, humans have been expanding their understanding of the world through more and more precise measurement of light and matter. Today, quantum sensors achieve extremely accurate results. An example of this is the development of atomic clocks, which are expected to neither gain nor lose more than a second in thirty billion years. Gravitational waves were detected via quantum sensors as well, in this case by using optical interferometers.
Scientists from Far Eastern Federal University (FEFU), V.I. Vernadsky Crimean Federal University, Dmitry Mendeleev University of Chemical Technology, and Far Eastern Branch of the Russian Academy of Sciences (FEB RAS), assumed the risks of primary skin cancer and its recurrences can be significantly reduced by applying the ointment with antisense oligonucleotides which are short DNA, RNA fragments used in oncology to suppress the synthesis of tumor proteins. A related review was published in Molecules.
Producing high-quality and realistic water wave animations that interact with complex objects is often computationally expensive with designers frequently opting for methods that are fast to compute but of lower quality. Researchers at the Institute of Science and Technology Austria (IST Austria) have developed a technique to produce more realistic water wave animations at a similar computational expense as compared to current approaches. The results are published in the journal ACM - Transactions on Graphics today.
