Nanotechnology news

	Meet the high-performance single-molecule diode A team of researchers from Berkeley Lab and Columbia University has passed a major milestone in molecular electronics with the creation of the world's highest-performance single-molecule diode. Working at Berkeley Lab's Molecular Foundry, a U.S. Department of Energy (DOE) Office of Science User Facility, the team used a combination of gold electrodes and an ionic solution to create a single-molecule diode that outperforms the best of its predecessors by a factor of 50.
	Like paper, graphene twists and folds into nanoscale machines The art of kirigami involves cutting paper into intricate designs, like snowflakes. Cornell physicists are kirigami artists, too, but their paper is only an atom thick, and could become some of the smallest machines the world has ever known.
	Probe enables tumor investigation using complementary imaging techniques An organic dye that can light up cancer cells for two powerful imaging techniques providing complementary diagnostic information has been developed and successfully tested in mice by A*STAR researchers.
	Graphene supercurrents go ballistic Researchers with Europe's Graphene Flagship have demonstrated superconducting electric currents in the two-dimensional material graphene that bounce between sheet edges without scattering. This first direct observation of the ballistic mirroring of electron waves in a 2d system with supercurrents could lead to the use of graphene-based Josephson junctions in applications such as advanced digital logic circuits, ultrasensitive magnetometers and voltmeters.

Physics news

	Researchers demonstrate the world's first white lasers More luminous and energy efficient than LEDs, white lasers look to be the future in lighting and light-based wireless communication.
	Researchers build bacteria's photosynthetic engine Nearly all life on Earth depends on photosynthesis, the conversion of light energy into chemical energy. Oxygen-producing plants and cyanobacteria perfected this process 2.7 billion years ago. But the first photosynthetic organisms were likely single-celled purple bacteria that began absorbing near-infrared light and converting it to sulfur or sulfates about 3.4 billion years ago.
	Japanese team fires world's most powerful laser (Phys.org)—A team of researchers and engineers at Japan's Osaka University is reporting that they have successfully fired what they are claiming is the world's most powerful laser. In their paper published in the journal Plasma Physics and Controlled Fusion in 2012, the team described their laser and how it works.
	Physicists close in on world's most sensitive resonators In their quest to make the world's most precise sensors, Cornell physicists have developed a novel method of manipulating mechanical resonators to be sensitive enough to work at the quantum scale.
	Rogue wave theory to save ships Physicists have found an explanation for rogue waves in the ocean and hope their theory will lead to devices to warn ships and save lives.
	Scientists unlock secrets of stars through aluminium Physicists at the University of York have revealed a new understanding of nucleosynthesis in stars, providing insight into the role massive stars play in the evolution of the Milky Way and the origins of the Solar System.
	Detecting small metallic contaminants in food via magnetization The detection of metallic contaminants in foods is important for our health and safety. However, existing inspection methods have limitations. For instance, the X-ray radiation method cannot detect contaminants with sizes smaller than 1 mm with current practical X-ray levels, and it cannot be applied for the inspection of foods that have lactic acid bacteria because X-ray radiation causes ionization of such foods.
	Colonoscopies of the future: Adjustable-focus endoscope helps to reduce discomfort Colonoscopy is a safe and effective medical procedure that's proven to saves lives. Used for routine cancer screening, it can help identify colon tumors in their early stages. In addition, it is a key non-surgical imaging technique that allows doctors to spot ulcers, polyps or bleeding inside the large intestines of their patients safely, avoiding complications that an exploratory surgery might induce.
	NIST PET phantoms bring new accuracy to medical scans Teaming with a medical equipment company, researchers at the National Institute of Standards and Technology (NIST) have demonstrated the first calibration system for positron emission tomography (PET) scanners directly tied to national measurement standards. Better calibrations of the machines potentially can increase the accuracy of their diagnostic images by several times, according to NIST scientists.

Earth news

	Playing 'tag' with pollution lets scientists see who's 'it' Using a climate model that can tag sources of soot from different global regions and can track where it lands on the Tibetan Plateau, researchers have determined which areas around the plateau contribute the most soot—and where. The model can also suggest the most effective way to reduce soot on the plateau, easing the amount of warming the region undergoes.
	New research will boost grasp of North American carbon cycle For centuries, people have transformed and splintered landscapes and ecosystems in North America. This radical altering of nature makes it tough for scientists to analyze the continent's life-sustaining carbon cycle—the biological, geological and chemical routes the element carbon takes to shift among earth, water and atmosphere.
	Earth sciences researcher examines string of related disasters striking Nepal For Nepal, the hits just keep coming.
Researcher finds way to cut cost, save water and help the environment by changing one simple thing Sanjay Shukla looked out over row upon row of tomato and pepper plants and had an idea: What would happen if he made the compacted soil rows taller and more narrow?

	Antarctic research and king crabs connect the climate change dots Biological science student and antarctic researchers shipped out this past winter to the wilds of the Antarctic in pursuit of rare and valuable data as part of the bi-annual SeaScience Expedition. The Antarctic is a place of extremes, relatively untouched by man and an ideal location to research the impact of climate change.
The challenge of mining rare-earth materials outside China Five years ago, the cost of rare-earth materials that are critical for today's electronics went through the roof. An export quota set by China, which mines most of the world's rare earths, caused the price run-up. Though short-lived, the occurrence spurred calls for developing mines outside China, but whether others can challenge the country's dominance remains to be seen, reports Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.
Ongoing recovery efforts take toll on hurricane survivors Superstorm Sandy continues to affect the lives of tens of thousands of New Jersey residents, in the form of unfinished repairs, disputed claims, and recurrent mold. These after-effects still linger for Sandy-impacted residents, and are associated with increased odds of residents experiencing mental health distress, post-traumatic stress disorder (PTSD), and depression.
	As desert encroaches, Niger turns to natural gas Threatened by the advance of a desert that already covers two-thirds of Niger, the poor Sahel nation hopes to halt rapid deforestation by promoting natural gas.

Astronomy & Space news

	First detection of lithium from an exploding star The chemical element lithium has been found for the first time in material ejected by a nova. Observations of Nova Centauri 2013 made using telescopes at ESO's La Silla Observatory, and near Santiago in Chile, help to explain the mystery of why many young stars seem to have more of this chemical element than expected. This new finding fills in a long-missing piece in the puzzle representing our galaxy's chemical evolution, and is a big step forward for astronomers trying to understand the amounts of different chemical elements in stars in the Milky Way.
	Brown dwarf stars host powerful aurora displays, astronomers discover Brown dwarf stars host powerful aurora displays just like planets, astronomers have discovered.
	New names and insights at Ceres Colorful new maps of Ceres, based on data from NASA's Dawn spacecraft, showcase a diverse topography, with height differences between crater bottoms and mountain peaks as great as 9 miles (15 kilometers).
	NASA Mars orbiter preparing for Mars lander's 2016 arrival With its biggest orbit maneuver since 2006, NASA's Mars Reconnaissance Orbiter (MRO) will prepare this week for the arrival of NASA's next Mars lander, InSight, next year.
	Dense star clusters shown to be binary black hole factories The coalescence of two black holes—a very violent and exotic event—is one of the most sought-after observations of modern astronomy. But, as these mergers emit no light of any kind, finding such elusive events has been impossible so far.
Spaceship pilot describes harrowing free fall after breakup Free-falling miles above the desert, his test spaceship ripped to pieces and the frigid air hard to breathe, pilot Peter Siebold struggled through crippling injuries to turn on his oxygen and just to stay conscious.
	Russia schedules first Proton rocket launch since crash Russia on Wednesday set a date for the first Proton rocket launch since an engine failure in May saw a Mexican satellite destroyed.
	Mystery at misfits flat An amateur has discovered a trove of meteorites on Misfits Flat dry lake in Nevada. No meteorites had been found at this tiny lakebed before. In an unusual twist, at least some of those turn out to have fallen less than 300 years ago.
	Eris' moon Dysnomia Ask a person what Dysnomia refers to, and they might venture that it's a medical condition. In truth, they would be correct. But in addition to being a condition that affects the memory (where people have a hard time remembering words and names), it is also the only known moon of the distant dwarf planet Eris.
	Faces of the solar system "Look, it has a tiny face on it!"
	Neptune's moon of Triton The planets of the outer solar system are known for being strange, as are their many moons. This is especially true of Triton, Neptune's largest moon. In addition to being the seventh-largest moon in the solar system, it is also the only major moon that has a retrograde orbit – i.e. it revolves in the direction opposite to the planet's rotation. This suggests that Triton did not form in orbit around Neptune, but is a cosmic visitor that passed by one day and decided to stay.
Annual Perseid meteor shower promises a fine display The annual Perseid meteor shower is one of the best and most reliable meteor showers of the year. It peaks every year around the 12th/13th August, and under ideal conditions produces a maximum frequency of meteors, or zenith hourly rate, up to around 100 meteors per hour. If you have never seen a meteor, this August—weather permitting—will provide the ideal opportunity. The weather is still reasonably mild, and the Moon, whose light often drowns out many faint meteors, is waning towards New Moon on the 14th and so will not interfere with the peak of this year's shower.
	NASA tells lawmakers to brace for more Pluto secrets revealed by mission Hoping to capture lawmakers' imaginations and perhaps loosen their purse strings, NASA officials said Tuesday that the new scientific information gleaned from the New Horizons mission to Pluto was "revolutionizing" what they know about the icy dwarf planet.
	NASA's MMS formation will give unique look at magnetic reconnection On July 9, 2015 the four spacecraft of NASA's Magnetospheric Multiscale, or MMS, mission began flying in a pyramid shape for the first time. The four-sided pyramid shape—called a tetrahedron—means that scientists' observations will be spread out over three dimensions.

Technology news

	Researchers mount successful attacks against Tor network—and show how to prevent them With 2.5 million daily users, the Tor network is the world's most popular system for protecting Internet users' anonymity. For more than a decade, people living under repressive regimes have used Tor to conceal their Web-browsing habits from electronic surveillance, and websites hosting content that's been deemed subversive have used it to hide the locations of their servers.

	Fujitsu develops technology to visualize the energy required to execute software Fujitsu Laboratories today announced that it has developed technology that precisely calculates the energy required to execute various software programs running on server CPUs, for energy-efficient programming. Servers equipped with Intel-made CPUs include a power-control mechanism that can measure power consumption for the CPU as a whole. Until now, however, it was not possible to calculate the energy required to execute software on a core-by-core basis, so it has been difficult to take a software-based approach to reducing power consumption. Now Fujitsu Laboratories has developed technology that uses information that can be tracked at the individual core level, such as clock cycles and cache-hit percentages, to estimate energy consumption in detail, down to the program module level. This makes energy-efficient programming a more efficient process, contributing to both lower overall server energy usage and, by using surplus power! , higher software performance. Details of this technology are being presented at the Summer United Workshops on Parallel, Distributed and Cooperative Processing 2015 (SWoPP 2015), opening in Beppu, Oita Prefecture, on August 4.

Chemistry news

	Researchers develop technology to reduce cost of purifying natural gas Researchers at Queen's University Belfast have developed a cutting-edge method of reducing the carbon dioxide content of natural gas, a process of major economic and environmental importance in the oil and gas industry.
	Don't call them stiff: Metal organic frameworks show unexpected flexibility Metal organic frameworks (MOFs) are proving to be incredibly flexible with a myriad of potential applications including as antimicrobial agents, hydrogen-storage materials and solar-cell components. And despite their rigid-sounding name, researchers are reporting that MOF structures are also dynamic—much more so than previously thought. They report this discovery, which could lead to the synthesis of brand-new types of materials, in ACS Central Science.
	Boxfish shell inspires new materials for body armor and flexible electronics The boxfish's unique armor draws its strength from hexagon-shaped scales and the connections between them, engineers at the University of California, San Diego, have found.
	Yarn from slaughterhouse waste ETH researchers have developed a yarn from ordinary gelatine that has good qualities similar to those of merino wool fibers. Now they are working on making the yarn even more water resistant.
	Phosphorus-based ligand facilitates palladium-catalyzed complex molecules The scope and productivity of an essential palladium-catalyzed coupling reaction that generates complex molecules has been improved thanks to A*STAR research that uses low-reactivity materials.
	Figuring out how to make tastier wines using fewer pesticides Wine-making is steeped in age-old traditions, but to address the threat of pests and concerns over heavy pesticide use, vintners are turning to science. With the goal of designing better grape breeds, scientists are parsing the differences between wild American grapes—which make terrible wine but are pest-resistant—and the less hardy grape species pressed for fine wines worldwide. They report their findings in ACS' Journal of Agricultural and Food Chemistry.
	An all-natural sunscreen derived from algae For consumers searching for just the right sunblock this summer, the options can be overwhelming. But scientists are now turning to the natural sunscreen of algae—which is also found in fish slime—to make a novel kind of shield against the sun's rays that could protect not only people, but also textiles and outdoor materials. They report on their development in the journal ACS Applied Materials & Interfaces.
	Toward a safe antiobesity drug that could block fat absorption To help address the global obesity epidemic, scientists are developing a new class of compounds called "micelle sequestrant polymers," or MSPs, that could prevent fat particles from getting absorbed in the body and thus potentially reduce weight gain.

Biology news

	Researchers design first artificial ribosome Researchers at the University of Illinois at Chicago and Northwestern University have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins and enzymes within the cell. The engineered ribosome may enable the production of new drugs and next-generation biomaterials and lead to a better understanding of how ribosomes function.
	Stressed out plants send animal-like signals University of Adelaide research has shown for the first time that, despite not having a nervous system, plants use signals normally associated with animals when they encounter stress.
	Study shows a way to tell if your hamster is happy (Phys.org)—A pair of researchers at Liverpool John Moores University in the U.K. believe they have found a way to measure happiness in hamsters. In their paper published in Royal Society Open Science, Emily Bethell and Nicola Koyama describe behavioral studies they carried out with hamsters, what they learned and why they believe their results indicate that hamsters, like other mammals, have feelings, or moods.
	Structures reveal basis of recurring urinary tract infections While the best antibiotics can wipe out most of the bacteria that cause notoriously difficult urinary tract infections, a few "sleeper cells" often remain. These "persisters," as they are called, survive by going dormant, essentially sleeping through the attack that kills off their more active brethren.
	Researchers discover new type of mycovirus Researchers, led by Dr Robert Coutts, Leverhulme Research Fellow from the School of Life and Medical Sciences at the University of Hertfordshire, and Dr Ioly Kotta-Loizou, Research Associate at Imperial College, have discovered a completely novel type of mycovirus.

	Simulated seawater flooding decreases growth of vegetable seedlings Crop production in coastal areas is threatened by seawater intrusion, which increases soil salinity. Excessive salinity in soil and irrigation water, in combination with waterlogging, can significantly affect the growth and quality for agricultural crops, especially those vegetables that are sensitive to salinity. A new study determined salt-tolerant vegetable seedlings for coastal area production.
Study of birds' sense of smell reveals important clues for behavior and adaptation From slight sparrows to preening peacocks to soaring falcons, birds have long been known to possess distinct abilities in their sense of smell, but little has been known about the evolution of olfaction.
	USDA scientist helps Texas sorghum growers reduce water use As water becomes more precious in the Texas High Plains, more farmers are likely to turn to sorghum because it's more drought tolerant than corn and produces higher yields under moderate to severe drought. With recent droughts and water shortages, many farmers have suffered major losses raising corn. The problem is compounded because the region depends on the Ogallala Aquifer for water, which is being depleted. Many farmers' wells are pumping less water today than in the past.
	Varying animal research standards are leading to bad science Scientific research sometimes requires the use of animals. It's a fact. And as long as that is the case, we need to do everything in our power to minimise the distress for laboratory animals. This is not just for the sake of the animals, but also for the sake of science itself. We know that the quality of life of an animal can actually affect its physiology and, thereby, the research data.
	Management strategies to reduce catfacing in peaches For producers of peaches and other orchard-grown produce, managing the orchard floor can present challenges. Unwelcome vegetation on the orchard floor competes with trees for water and nutrients reducing tree growth and productivity, and can be a host for pathogens and insect pests. Utilizing best practices for irrigation and vegetation management in the orchard helps growers to optimize tree growth, fruit yield, and fruit size. Scientists at North Carolina State University published a study in the May 2015 issue of HortScience that includes guidelines that can help increase tree vigor and fruit yield, and limit damage from hemipteran or "catfacing" insects - pests that damage and distort peaches and other fruit.
	Light-emitting diode sole-source lighting effective in bedding plant seedling production In northern latitudes, producers of bedding plants depend on supplemental lighting during the late winter and early spring growing seasons. Unfortunately, these peak times for young plant production are also the darkest. Researchers have determined that a minimum amount of photosynthetic light (daily light integral; DLI) is necessary to produce high-quality young plants in greenhouses. In northern latitudes, though, the average greenhouse photosynthetic DLI can fall far short of optimal levels, resulting in delayed production and poor quality plants.
Malic acid encourages sweet cherry cracking "Cracking" is a problem for sweet cherry production wherever the high-value crop is grown. However, despite considerable research, the reason that this phenomenon occurs has not been clear. In a new study, Andreas Winkler, Max Ossenbrink, and Moritz Knoche reveal their discovery of what makes sweet cherries crack.
End-of-production LED lighting increases red pigmentation in lettuce Growing vegetables in greenhouses extends crop production seasons in northern latitudes, but the greenhouse environment is far from ideal for providing plants with optimal photosynthetic light. In fact, available photosynthetic daily light in greenhouses can be reduced by up to 50% or more by the structures' glazing material, superstructure, and shading. In northern latitudes, low light is considered the most limiting environmental factor in greenhouse vegetable production.

Medicine & Health news

	Women's immune system genes operate differently from men's, study finds A new technology for studying the human body's vast system for toggling genes on and off reveals that genes associated with the immune system toggle more frequently, and those same genes operate differently in women and men.
	Long telomere length associated with increased lung cancer risk A large-scale genetic study of the links between telomere length and risk for five common cancers finds that long telomeres are associated with an increased risk of lung adenocarcinoma. No significant associations between telomere length and other cancer types or subtypes were observed. The study, led by scientists from the University of Chicago, uses a novel method to measure genetic predisposition for telomere length, rather than physiological measures which are confounded by factors such as age and lifestyle. The findings are published in Human Molecular Genetics on July 29, 2015.
	Proof-of-concept study shows successful transport of blood samples with small drones In a proof-of-concept study at Johns Hopkins, researchers have shown that results of common and routine blood tests are not affected by up to 40 minutes of travel via hobby-sized drones.
	Antibiotics increase risk of hearing loss in patients with deadly bacterial infections Seeking to stem the tide of permanent hearing loss from the use of life-saving antibiotics, researchers at Oregon Health & Science University have found that patients stricken with dangerous bacterial infections are at greater risk of hearing loss than previously recognized. Inflammation from the bacterial infections substantially increased susceptibility to hearing impairment by increasing the uptake of aminoglycoside antibiotics into the inner ear, the researchers report. Their findings are published in online in the journal Science Translational Medicine.
	Using proliferative properties of cancer cells to rejuvenate cardiac progenitor cells In a way, trying to repair age-related heart damage and trying to fight cancer are opposite problems. Your heart cells' ability to regenerate themselves and proliferate into new, young cells degrades as you get older. They simply lose their proficiency at cell division. Cancer cells, on the other hand, are too good at proliferating. They don't know when to stop, and the overgrowth results in tumors.
