Nanotechnology news

	Scientists show how salt lowers reaction temperatures to make novel materials A dash of salt can simplify the creation of two-dimensional materials, and thanks to Rice University scientists, the reason is becoming clear.
	Scientists create gold nanoparticles in water An experiment that, by design, was not supposed to turn up anything of note instead produced a "bewildering" surprise, according to the Stanford scientists who made the discovery: a new way of creating gold nanoparticles and nanowires using water droplets.
	Robot developed for automated assembly of designer nanomaterials Van der Waals heterostructures are assemblies of atomically thin two-dimensional (2-D) crystalline materials that display attractive conduction properties for use in advanced electronic devices.
	New record on squeezing light to one atom: Atomic Lego guides light below one nanometer All electronic devices consist of billions of transistors, the key building block invented in Bell Labs in the late 1940s. Early transistors were as large as one centimeter, but now measure about 14 nanometers. There has also been a race to further shrink devices that control and guide light. Light can function as an ultra-fast communication channel, for example, between different sections of a computer chip, but it can also be used for ultra-sensitive sensors or novel on-chip nanoscale lasers.
	New cancer monitoring technology worth its weight in gold A new blood test using gold nanoparticles could soon give oncologists an early and more accurate prognosis of how cancer treatment is progressing and help guide the on-going therapy of patients.
	Electrochemical tuning of single layer materials relies on defects Perfection is not everything, according to an international team of researchers whose 2-D materials study shows that defects can enhance a material's physical, electrochemical, magnetic, energy and catalytic properties.
	Peptide induces chirality evolution in a single gold nanoparticle For the first time, scientists have successfully created optically active, chiral gold nanoparticles using amino acids and peptides. Many chemicals significant to life have mirror-image twins (left-handed and right-handed structures), a characteristic that is conventionally called chirality. This study describes how chirality, which is typically observed in organic molecules, can be extended to three-dimensional metallic nanostructures. This newly discovered synthesis method was described in Nature and was featured on the cover.
	Graphene changes elastic properties depending on applied force A group of scientists, including specialists from Landau Institute for Theoretical Physics (ITF), has described a universal characteristic in which many unique graphene properties are "hidden." Abnormal graphene behavior can be fully characterised by the Poisson ratio, which determines a material's capability to shrink or extend in a transverse dimension. Moreover,scientists found key factors that can influence this characteristic. The results are published in Physical Review B.

Physics news

	Diamond can turn flexible when made into ultrafine needles, researchers find Diamond is well-known as the strongest of all natural materials, and with that strength comes another tightly linked property: brittleness. But now, an international team of researchers from MIT, Hong Kong, Singapore, and Korea has found that when grown in extremely tiny, needle-like shapes, diamond can bend and stretch, much like rubber, and snap back to its original shape.
	New research could literally squeeze more power out of solar cells Physicists at the University of Warwick have today, Thursday 19th April 2018, published new research in the fournal Science today 19th April 2018 (via the Journal's First Release pages) that could literally squeeze more power out of solar cells by physically deforming each of the crystals in the semiconductors used by photovoltaic cells.
	New microscope captures detailed 3-D movies of cells deep within living systems Our window into the cellular world just got a whole lot clearer.
	Researchers use diamond impurities to see on the microscopic scale It's not often that you see 50-year-old equipment in a modern physics laboratory, let alone find it at the center of cutting-edge research. But then, most such labs aren't run by Ronald Walsworth.
	Atoms may hum a tune from grand cosmic symphony Researchers playing with a cloud of ultracold atoms uncovered behavior that bears a striking resemblance to the universe in microcosm. Their work, which forges new connections between atomic physics and the sudden expansion of the early universe, was published April 19 in Physical Review X and featured in Physics.
	Integrating optical components into existing chip designs Two and a half years ago, a team of researchers led by groups at MIT, the University of California at Berkeley, and Boston University announced a milestone: the fabrication of a working microprocessor, built using only existing manufacturing processes, that integrated electronic and optical components on the same chip.
	Researchers find new way of exploring the afterglow from the Big Bang Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background radiation. The new results predict the maximum bandwidth of the universe, which is the maximum speed at which any change can occur in the universe.
	For nuclear weapons reduction, a way to verify without revealing In past negotiations aimed at reducing the arsenals of the world's nuclear superpowers, chiefly the U.S. and Russia, a major sticking point has been the verification process: How do you prove that real bombs and nuclear devices—not just replicas—have been destroyed, without revealing closely held secrets about the design of those weapons?
	Writing and deleting magnets with lasers Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia have found a way to write and delete magnets in an alloy using a laser beam, a surprising effect. The reversibility of the process opens up new possibilities in the fields of material processing, optical technology, and data storage.
	Ultrafast electron oscillation and dephasing monitored by attosecond light source Collaborative research team of Prof. Jun Takeda and Associate Prof. Ikufumi Katayama in the laboratory of Yokohama National University (YNU) and Nippon Telegraph and Telephone (NTT) have reported petahertz electron oscillation. The periodic electron oscillations of 667-383 attoseconds (10-18 of a second) is the fastest that has ever been measured in direct time-dependent spectroscopy in solid-state material.
	Electromagnetic wizardry: Wireless power transfer enhanced by backward signal An international research team including scientists from the Moscow Institute of Physics and Technology and ITMO University has proposed a way to increase the efficiency of wireless power transfer over long distances and tested it with numerical simulations and experiments. To achieve this, they beamed power between two antennas, one of which was excited with a back-propagating signal of specific amplitude and phase. The study is detailed in a paper published in Physical Review Letters and briefly reported in the American Physical Society journal Physics.
	Diamond-like carbon is formed differently to what was believed – machine learning enables development of new model Researchers at Aalto University and Cambridge University have made a significant breakthrough in computational science by combining atomic-level modeling and machine learning. For the first time, the method has been used to realistically model how an amorphous material is formed at the atomic level: that is, a material that does not have a regular crystalline structure. The approach is expected to have impact on the research of many other materials.
	Charge density wave inhomogeneity and pseudogap in 1T-TiSe2 1T-TiSe2 has been widely studied in the past few decades as one of the typical charge density wave (CDW) materials. Recently, superconductivity was realized in this system through Cu intercalation, pressure or electric gating, forming a dome-shaped superconductivity phase diagram. Owing to this resemblance to high -Tc cuprates, much attention has been paid to 1T-TiSe2 to understand the superconducting mechanism and its interplay with CDW. However, it is still under debate whether CDW competes with superconductivity or not. Via tuning the dopant level, 1T-TiSe2 system can undergo the transition from CDW to superconductivity, and thus provides an ideal platform to study the relationship between these two states.

Earth news

	Researchers find that swarms of tiny organisms mix nutrients in ocean waters Swarms of tiny oceanic organisms known collectively as zooplankton may have an outsize influence on their environment. New research at Stanford shows that clusters of centimeter-long individuals, each beating tiny feathered legs, can, in aggregate, create powerful currents that may mix water over hundreds of meters in depth.
	Hurricane Harvey: Research shows most fatalities occurred outside flood zones A Dutch-Texan team found that most Houston-area drowning deaths from Hurricane Harvey occurred outside the zones designated by government as being at higher risk of flooding: the 100- and 500-year floodplains. Harvey, one of the costliest storms in US history, hit southeast Texas on 25 August 2017 causing unprecedented flooding and killing dozens. Researchers at Delft University of Technology in the Netherlands and Rice University in Texas published their results today in the European Geosciences Union journal Natural Hazards and Earth System Sciences.
	Great Barrier Reef corals can survive global warming for another century Using genetic samples and computer simulations, evolutionary biologists have made a glass-half-full forecast: Corals in the Great Barrier Reef have enough genetic variation to adapt to and survive rising ocean temperatures for at least another century, or more than 50 years longer than previous estimates have suggested.
	California has worst US air pollution: report California has the most polluted cities in the United States, a report issued on Wednesday said, as President Donald Trump's administration seeks to force the state to weaken its vehicle emissions standards.
	Support rises for controversial Canada pipeline Support in Canada for a pipeline expansion to move oil to the Pacific coast for shipping to new markets overseas is rising, polling showed Wednesday as protests against it followed the prime minister to Britain.
	Alpine grassland productivity not sensitive to climate warming on third pole The Tibetan Plateau has experienced more rapid climate warming than the global average, coupled with greater inter-annual variation in precipitation over the past 50 years. How will such dramatic climate change influence the structure and function of alpine grasslands? Interest in this topic is high because of its importance to the sustainable development of animal husbandry and the livelihood of Tibetan inhabitants.
	California's next major earthquake could cause $100 billion in losses, strand 20,000 in elevators What will happen when the next big earthquake hits northern California? A team of researchers including CU Boulder Professor Keith Porter will explore that question at an event today marking the anniversary of the 1906 temblor that leveled much of San Francisco.

	Climate change could alter ocean food chains, leading to far fewer fish in the sea Climate change is rapidly warming the Earth and altering ecosystems on land and at sea that produce our food. In the oceans, most added heat from climate warming is still near the surface and will take centuries to work down into deeper waters. But as this happens, it will change ocean circulation patterns and make ocean food chains less productive.
	Small changes in rainforests cause big damage to fish ecosystems Freshwater fish diversity is harmed as much by selective logging in rainforests as they are by complete deforestation, according to a new study.
	No-go warning as Japan volcano erupts for first time in 250 years A volcano in southern Japan erupted for the first time in 250 years on Thursday, spewing steam and ash hundreds of metres into the air, as authorities warned locals not to approach the mountain.
	Eurasian atmospheric circulation anomalies can persist from winter to the following spring Surface air temperature (SAT) anomalies have pronounced impacts on agriculture, socioeconomic development, and people's daily lives. For example, the record-breaking hot summer over many parts of the Eurasia resulted in broad wildfires and serious economic losses. Many studies have demonstrated that atmospheric circulation anomalies play an important role in modulating the SAT variations. Hence, the persistent characteristics of the Eurasian atmospheric circulation anomalies are crucial for the seasonal prediction of the Eurasian SAT. A question is whether the Eurasian atmospheric circulation anomalies can persist from winter to the following spring.
	How does the Pacific Walker circulation respond to strong tropical volcanism? Recently, Mount Agung in Bali erupted again, attracting considerable attention. A potentially very large eruption could also take place in Bali. Strong tropical volcanic eruptions (SVEs) like this not only pose serious human risk, but can affect Earth's climate.
	Thousands of tons of e-waste is shipped illegally to Nigeria inside used vehicles A two-year study into used electrical and electronic equipment (UEEE) sent to Nigeria, mostly from European ports, has revealed a continuing "severe problem" of non-compliance with international and national rules governing such shipments.
	Deepwater horizon—the lasting impact of America's largest oil spill On April 20, 2010, the Deepwater Horizon oil platform operated by BP, was disconnecting from a recently discovered oil reservoir 50 miles south of Louisiana when a cascade of equipment malfunctions caused a high-pressure explosion, killing 11 rig workers. For two days the rig burned then sank. As response crews worked to extinguish surface fires, oil and gas from the broken drill pipe was spewing a mile deep in the Gulf of Mexico.
Toward a new water paradigm Good intentions are not the same as good results - as much as half of all water and sanitations systems in developing countries fail after five years.

	Virtually modelling the human brain in a computer Neurons that remain active even after the triggering stimulus has been silenced form the basis of short-term memory. The brain uses rhythmically active neurons to combine larger groups of neurons into functional units. Until now, neuroscientists have, for the most part, studied these and other properties with the help of network models, each of which is only able to recreate a single property. Scientists at the Max Planck Institute for Brain Research in Frankfurt have now shown how the new model can be used to investigate multiple properties in parallel. According to their calculations, all the properties share a common basis: ion channels in the cell membrane that control how strongly neurons are electrically stimulated. The emergence of these properties does not require synaptic plasticity – a finding that helps explain, for example, why some psychoactive drugs can have far-reaching side effects.

	Far-red fluorescent silk can kill harmful bacteria as biomedical and environmental remedy A silk hybrid material attacks bacteria when illuminated by a green light, thanks to a far-red fluorescent protein researchers transferred to its genetic makeup.
	Light-controlled current transport by charged atoms demonstrated for the first time Light makes some materials conductive in a previously unforeseen way. In silicon solar cells, electrons flow when the sun shines. However, scientists at the Stuttgart-based Max Planck Institute for Solid State Research have now come up with a surprise: in a special perovskite, another material used for solar cells, light not only releases electrons, but also electrically charged atoms, known as ions. Moreover, this novel photoeffect is extremely large. Ion conductivity increased by a factor of one hundred. For solar cells made from the material investigated here, the high light-induced ion conductivity is rather damaging; the consequences, however, can now be specifically counteracted. From the point of view of the researchers in Stuttgart, the effect is ground-breaking in itself, as it makes novel, light-controlled electrochemical applications conceivable, such as batteries directly charged by light.

Drug combination targeting HSP90 and BRAF is safe and effective in advanced melanoma Patients with advanced or metastatic melanoma have been able to live longer cancer-free lives because of several new therapies approved over the last decade, such as BRAF and MEK inhibitors. However, despite the success of these targeted agents, most patients eventually develop drug resistance and their cancer regrows. A team of researchers at Moffitt Cancer Center have been working to learn more about how melanoma becomes resistant to BRAF inhibitors in order to develop new treatment strategies. They tested whether a drug targeting heat shock protein 90 (HSP90) combined with the BRAF inhibitor vemurafenib could be a safe and potentially effective strategy to treat patients with melanoma. Their study was published online ahead of print in Clinical Cancer Research.
Landmark study links tumor evolution to prostate cancer severity Findings from Canadian Prostate Cancer Genome Network (CPC-GENE) researchers and their collaborators, published today in Cell, show that the aggressiveness of an individual prostate cancer can be accurately assessed by looking at how that tumour has evolved. This information can be used to determine what type and how much treatment should be given to each patient, or if any is needed at all.
	Study may explain why some triple-negative breast cancers are resistant to chemotherapy Triple-negative breast cancer (TNBC) is an aggressive form of the disease accounting for 12 to 18 percent of breast cancers. It is a scary diagnosis, and even though chemotherapy can be effective as standard-of-care, many patients become resistant to treatment. A team at The University of Texas MD Anderson led a study which may explain how resistance evolves over time, and potentially which patients could benefit from chemotherapy.
	Chip-based blood test for multiple myeloma could make bone biopsies a relic of the past The diagnosis and treatment of multiple myeloma, a cancer affecting plasma cells, traditionally forces patients to suffer through a painful bone biopsy. During that procedure, doctors insert a bone-biopsy needle through an incision to get a bone marrow sample—or make a larger incision and remove a section of bone via surgery.
	More students report carrying guns in Chicago than New York or Los Angeles More students report carrying guns in Chicago than in New York or Los Angeles, a new Northwestern Medicine study shows.

	British pilots score high on burnout scale—but still perform well A study among British airline pilots shows that 20 percent of them have scores on a burnout scale that are comparable to those of people that are under burnout treatment. Surprisingly, the same study shows that only one of the 1147 pilots that participated, did not meet the performance standards at the regular flight simulator training. The authors argue that airline companies need to offer better support and facilities to their pilots to help them cope with their stressful jobs. Their work is published in the journal Ergonomics.

3-D human 'mini-brains' shed new light on genetic underpinnings of major mental illness Major mental illnesses such as schizophrenia, severe depression and bipolar disorder share a common genetic link. Studies of specific families with a history of these types of illnesses have revealed that affected family members share a mutation in the gene DISC1. While researchers have been able to study how DISC1 mutations alter the brain during development in animal models, it has been difficult to find the right tools to study changes in humans. However, advancements in engineering human stem cells are now allowing researchers to grow mini-organs in labs, and gene-editing tools can be used to insert specific mutations into these cells. Researchers from Brigham and Women's Hospital are leveraging these new technologies to study the effects of DISC1 mutations in cerebral organoids - "mini brains" - cultured from human stem cells. Their results are published in Translational Psychiatry.
