	Super-resolution system reveals mechanics of tiny 'DNA walker' Researchers have introduced a new type of "super-resolution" microscopy and used it to discover the precise walking mechanism behind tiny structures made of DNA that could find biomedical and industrial applications.
	Nanotube growth moving in the right direction For the first time, Lawrence Livermore National Laboratory scientists and collaborators have captured a movie of how large populations of carbon nanotubes grow and align themselves.
	Unique properties of 2-D materials and metals grown on carbon-coated surfaces Two-dimensional materials are a bit of a mind-bending concept. Humans live in a three-dimensional world, after all, where everything observed in our natural world has height, width, and depth. And yet when graphene—a carbon material unique in its truly flat, one-atom-deep dimension—was first produced in 2004, the mind-bending concept became reality and an unexplored frontier in materials science.

Physics news

	Researchers use artificial neural network to simulate a quantum many-body system (Phys.org)—A pair of physicists with ETH Zurich has developed a way to use an artificial neural network to characterize the wave function of a quantum many-body system. In their paper published in the journal Science, Giuseppe Carleo and Matthias Troyer describe how they coaxed a neural network to simulate some aspects of a quantum many-body system. Michael Hush with the University of New South Wales offers a Perspectives piece on the work done by the pair in the same journal issue and also outlines the problems other researchers have faced when attempting to solve the same problem.
	Quest to settle riddle over Einstein's theory may soon be over Astronomy experiments could soon test an idea developed by Albert Einstein almost exactly a century ago, scientists say.
	New study of ferroelectrics offers roadmap to multivalued logic for neuromorphic computing Research published Wednesday, in Nature Scientific Reports lays out a theoretical map to use ferroelectric material to process information using multivalued logic - a leap beyond the simple ones and zeroes that make up our current computing systems that could let us process information much more efficiently.
	New laser technology enables more sensitive gravitational-wave detectors One year ago, the first direct detection of gravitational waves was announced. Laser experts from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI), from the Leibniz Universität Hannover, and from the Laser Zentrum Hannover e.V. (LZH) played leading roles in this discovery, because their super-precise laser technology at the heart of the LIGO instruments in the USA enabled the detection of weak gravitational-wave signals. Now, AEI researchers have presented two new technologies capable of further increasing the sensitivity of future gravitational-wave detectors. The Max Planck Society now strengthens the development of laser systems for third-generation gravitational-wave detectors. The AEI, in collaboration with the LZH, receives over the next five years 3.75 million Euro research funding for the development of novel lasers Zentrum Hannover receives over the next five years 3.75 million Euro research funding for the development of novel lasers and stabilization methods.

The source of the signal is a long-lost cosmological phenomenon called "oscillon". The journal Physical Review Letters has published the results.

Earth news

	Sea-level change in Southeast Asia 6,000 years ago has implications for today For the 100 million people who live within 3 feet of sea level in East and Southeast Asia, the news that sea level in their region fluctuated wildly more than 6,000 years ago is important, according to research published by a team of ocean scientists and statisticians, including Rutgers professors Benjamin Horton and Robert Kopp and Rutgers Ph.D. student Erica Ashe. That's because those fluctuations occurred without the assistance of human-influenced climate change.
	Car drivers cause the most pollution in London – but are least exposed to it themselves Car drivers in London are causing the most pollution per commuter, a new study by the University of Surrey has found. But drivers themselves are the commuters least exposed to harmful particulate matter (PM), when compared with those taking the Underground or the bus.
	Simulation suggests two plumes involved in producing Deccan Traps (Phys.org)—A pair of researchers with the University of Quebec has found evidence that suggests the formation of the Deccan Traps igneous province came about due to two eruptions from two distinct plumes. In their paper published in the journal Science, Petar Glišović and Alessandro Forte, describe how they created a computer simulation able to depict events that occurred in what is now India over 60 million years ago.
	Researchers develop genetic tool to improve arsenic studies Environmental engineers are making it easier to identify the bacterial species responsible for releasing a form of arsenic that contaminates the water supplies of millions of people worldwide.
	A daily disturbance from the upper atmosphere leaves its footprints on tropical rainfall No matter where you live, rain seems to fall more often at certain times of day, whether it is seen in the daily afternoon rainstorm or a typical overnight shower. Indeed, statistically, long-term average rainfall tends to cluster at certain times of the 24-hour cycle, but that time frame varies depending on location. A team of scientists led by postdoctoral researcher Takatoshi Sakazaki at UH Mānoa's International Pacific Research Center (IPRC) has analyzed satellite-based observations and computer model simulations of tropical rainfall variation throughout the day in an effort to determine the root cause of the temporal patterns. Their results, published recently in Geophysical Research Letters, show that daily tropical rainfall distribution is significantly shaped by heating of the upper atmosphere.
Cattle pastures and other degraded lands become new oil palm plantations A new study published last week in the journal Environmental Research Letters by researchers at the University of Puerto Rico offers the first regional look at lands being converted to palm oil plantations in Latin America. Palm oil is a primary ingredient in processed foods, soaps, cosmetics, and biofuel. Growth of the palm oil industry has caused widespread deforestation in Southeast Asia, a concern among conservationists, the private sector, and consumers.

	New insights into the roles of different subareas in the prefrontal cortex Whether the brain responds to an external stimulus or not depends significantly on the balance between areas of excitation and inhibition in the prefrontal cortex (PFC). Synaptic connections in the front of the cerebral cortex enable the brain to make a conscious decision on whether to react to a stimulus with movement or not. However, the roles of the individual regions in the PFC and how they work together in this decision-making process were unknown until now. An international team led by Stefanie Hardung from the research group of Professor Ilka Diester, a member of Bernstein Center Freiburg and the Cluster of Excellence BrainLinks-BrainTools, has now identified the roles five subareas in the prefrontal cortex play in making decisions on movement. Their results were now published in the journal Current Biology. This study may be of particular significance for the further investigation of impulse control disorders.

Scientists can predict in the lab whether a drug will be effective for individual colorectal tumours Colorectal carcinomas arise in different forms, so all treatments do not work for all patients. OncoTrack, a public-private consortium supported by the Innovative Medicines Initiative Joint Undertaking, has conducted one of Europe's largest collaborative academic-industry research projects to develop and assess novel approaches for identification of new markers for colon cancer. Scientists from the OncoTrack Consortium, including researchers from the Max Planck Institute for Molecular Genetics in Berlin and the Institute's spin-off Alacris Theranostocs, have analysed tumour samples from patients with this type of cancer in a preclinical study. In particular, the scientists looked for biomarkers, i.e. molecules that are typical of the different tumour sub-groups and provide valuable information for diagnosis and potential treatment. Among other things, the research team discovered molecules that can predict the effectiveness of two drugs commonly used to treat this disease: Cetuximab, which inhibits the receptor for the epidermal growth factor (EGFR), and the chemotherapy drug 5FU.
