Nanotechnology news

	Heart-shaped Li-ion battery printed on a cup shows batteries can be printed almost anywhere Scientists have developed a new technique that can print batteries on almost any surface, which is expected to be essential for future flexible electronics such as roll-up displays, smart electronic clothing, and Google Glass-type devices. Whereas today's Li-ion batteries can be fabricated only in fixed shapes and sizes, such as cylinders or pouch cells, the new Li-ion batteries can be printed in their entirety—including electrodes and electrolyte—almost anywhere. The researchers even predict that in the future the batteries could be printed with a 3D printer into various 3D shapes.
	Large-area integration of quantum dots and photonic crystals produce brighter and more efficient light Recently, quantum dots (QDs)—nano-sized semiconductor particles that produce bright, sharp, color light—have moved from the research lab into commercial products like high-end TVs, e-readers, laptops, and even some LED lighting. However, QDs are expensive to make so there's a push to improve their performance and efficiency, while lowering their fabrication costs.
	A new technique for making 2D transistors from dual-phase TMD crystals Molybdenum ditelluride (MoTe2)  is a crystalline compound that, if pure enough, can be used as a transistor. Its molecular structure is an atomic sandwich made up of one molybdenum atom for every two tellurium atoms.  It was first made in the 1960s via several different fabrication methods, but until last year, it had never been made in a pure enough form to be suitable for electronics.
	Pouring fire on fuels at the nanoscale There are no magic bullets for global energy needs. But fuel cells in which electrical energy is harnessed directly from live, self-sustaining chemical reactions promise cheaper alternatives to fossil fuels.

Physics news

	Fermilab experiment sees neutrinos change over 500 miles Scientists on the NOvA experiment saw their first evidence of oscillating neutrinos, confirming that the extraordinary detector built for the project not only functions as planned but is also making great progress toward its goal of a major leap in our understanding of these ghostly particles.
	Focused laser power boosts ion acceleration An international team of physicists has used carbon nanotubes to enhance the efficiency of laser-driven particle acceleration. This significant advance brings compact sources of ionizing radiation for medical purposes closer to reality.
	Innovative components for an imaging system in the terahertz range Terahertz frequencies offer the unique feature of displaying things that in other frequency ranges such as the visible, microwave or X-ray, would be impossible. So they are able to image a ceramic weapon or a parcel bomb hidden under clothing, or skin cancer in its early stages, and even the properties of certain foods. In her PhD thesis, read at the NUP/UPNA-Public University of Navarre, Itziar Maestrojuán-Biurrun has developed specific technology for imaging applications in this frequency range.
	Charge density and optical properties of multicomponent crystals Optical materials serve a major role in modern sciences and technology. Many of the devices we use feature technology resulting from material discoveries in this fast moving area of research. Nowadays, the need for more efficient devices and minimisation in optoelectronics requires a novel approach towards crystal engineering of functional solids.

Earth news

	End-Permian mass extinction may have been driven by an ocean teeming with life (Phys.org)—The Permian geologic period that ended the Paleozoic era climaxed around 252 million years ago with a sweeping global mass extinction event in which 90 to 95 percent of marine life became extinct. It would take 30 million years for planetary biodiversity to recover. Understanding the contributing factors of the end-Permian mass extinction is critical to understanding and perhaps mitigating the current anthropogenic climate change.
	Delta cities, wealthy or not, face rising risk from sinking land Coastal deltas are becoming more at risk of flooding due to land subsidence, or the gradual sinking of the Earth's surface, and sea-level rise.
	In Africa, more smoke leads to less rain, NASA shows A new NASA study shows that agricultural fires in North Africa reduce the region's rainfall during the dry season, in a longstanding example of humans unintentionally modifying weather and regional climate. The study is the first to use satellite observations to answer the question of how smoke from these fires affects rainfall.
	Fish go deep to beat the heat A James Cook University study shows fish retreating to deeper water to escape the heat, a finding that throws light on what to expect if predictions of ocean warming come to pass.
	Researcher calls for more natural baseline data collection in world's oceans In the spring of 2010, the Deepwater Horizon drilling platform exploded, initiating an uncontrolled deep-water oil and gas blowout from the Macondo wellhead. The uncontrolled hydrocarbon discharge continued for 85 days and the environmental impacts were substantial.
When is the price right for selling water? Research from the University of Adelaide has provided new insights into how Australian farmers and irrigators may respond to certain market conditions, and when they are more likely to sell their water entitlements.
	The social value of flood alleviation Climate change is predicted to increase the frequency and severity of flooding in coming years. For more effective flood alleviation, a recently published study recommends schemes that consider the social impact of floods as well as the economic damages.
	Cutting emissions through biofuels will lead to water shortages – study Climate change mitigation could actually increase water shortage in some areas rather than reduce it, according to new research. The source of the problem is clear: greater demand for biofuels, intended to reduce emissions from fossil fuels, requires massive increases in irrigation in productive but relatively arid American farmland.
	Philippines' Aeta people 'beggars' in their own land Philippine bush man Edward Serrano struck two rocks together and wrapped the faint spark in wood shavings, building a fire in much the same way Stone Age man must have done two million years ago.

Astronomy & Space news

	Bright spots and a pyramid-shaped mountain on Ceres Striking 3-D detail highlights a towering mountain, the brightest spots and other features on dwarf planet Ceres in a new video from NASA's Dawn mission.
	Scientists discover elusive gamma-ray pulsar with distributed computing project Gamma-ray pulsars are remnants of explosions that end the lives of massive stars. They are highly-magnetized and rapidly rotating compact neutron stars. Like a cosmic lighthouse they emit gamma-ray photons in a characteristic pattern that repeats with every rotation. However, since only very few gamma-ray photons are detected, finding this hidden rhythm in the arrival times of the photons is computationally challenging. Now, an international team led by researchers at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) in Hannover, Germany, has discovered a new gamma-ray pulsar hidden in plain sight in data from the Fermi Gamma-ray Space Telescope. The improved, adaptive data analysis methods and the computing power from the distributed volunteer computing project Einstein@Home were key to their success.
	Salt flat indicates some of the last vestiges of Martian surface water Mars turned cold and dry long ago, but researchers at the University of Colorado Boulder have discovered evidence of an ancient lake that likely represents some of the last potentially habitable surface water ever to exist on the Red Planet.
	Corrected sunspot history suggests climate change not due to natural solar trends The Sunspot Number is a crucial tool used to study the solar dynamo, space weather and climate change. It has now been recalibrated and shows a consistent history of solar activity over the past few centuries. The new record has no significant long-term upward trend in solar activity since 1700, as was previously indicated. This suggests that rising global temperatures since the industrial revolution cannot be attributed to increased solar activity.
	Q&A: A look at the science on Hawaii's Mauna Kea Atop Hawaii's Mauna Kea, where some Native Hawaiians have been peacefully protesting the construction of what would be one of the world's largest telescopes, astronomers have spent the past 40 years observing our universe and helping make some of the most significant discoveries in their field.
	Saturn's rings in a supercomputer Why do some planets, like Saturn or Jupiter, have rings, while others, like Earth or Mars, do not? It turns out that "size does not matter"—gas giants like Saturn are not the only bodies that can possess rings; even tiny asteroids do. According to a recent discovery of the Spitzer Space Telescope, the remote asteroid Chariklo, which is only 260 km in diameter, also has rings.
	Stealing Sedna Turns out, our seemly placid star had a criminal youth of cosmic proportions.
	The moons of Saturn Saturn is well known for being a gas giant, and for its impressive ring system. But it would it surprise you to know that this planet also has the second-most moons in the solar system, second only to Jupiter? Yes, Saturn has at least 150 moons and moonlets in total, though only 53 of these moons have been given official names.
	Taking plants off-planet – how do they grow in zero gravity? Gravity is a constant for all organisms on Earth. It acts on every aspect of our physiology, behavior and development – no matter what you are, you evolved in an environment where gravity roots us firmly to the ground.
	Space mining is closer than you think, and the prospects are great In this week's Q&A on the ABC, the American cosmologist Neil deGrasse Tyson gushed about the prospects of mining in space, and the benefits that might afford humanity.
	Perseid meteors to light up summer skies The evening of Wednesday 12 August into the morning of Thursday 13 August sees the annual maximum of the Perseid meteor shower. This year, a new moon makes prospects for watching this natural firework display particularly good.
	NASA Goddard involved in New Horizons from start Three billion miles of space travel and 26 years of careful planning and execution ago, New Horizons Principal Investigator Alan Stern, now of the Southwest Research Institute in Boulder, Colorado, gave his first talk about a theoretical mission to Pluto at the weekly science symposium at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Chemistry news

	Copper clusters capture and convert carbon dioxide to make fuel Capture and convert—this is the motto of carbon dioxide reduction, a process that stops the greenhouse gas before it escapes from chimneys and power plants into the atmosphere and instead turns it into a useful product.
	Mathematical kinetics model accurately depicts grain-level corrosion plaguing metal alloys A core concern for any structural material is maintaining a prolonged, effective service life. Notably, critical metal alloy failures typically initiate beyond the naked eye, where intergranular (between the grains) oxidation combines with stress corrosion, causing cracks. Even worse, these corrosive attacks ultimately can result in total metal alloy failure. In their work examining intergranular attack of alloys under hydrothermal conditions, scientists from PNNL's ACMD Division Computational Mathematics group, Physical Sciences Division, and Energy and Environment Directorate developed a mathematical model that is directly comparable to experimental data in predicting how fast oxygen penetrates binary alloys and the resulting depletion of select elements in the materials that leads to failures. Their work reveals insights into oxidation mechanisms at the atomic level that provide a new perspective on ways to improve materials durability.
	Protein may trigger cancer cell's metabolism New research from the University of Central Florida has shed light on the workings of a particular protein found in the human body that could have future implications for the treatment of cancer and neurodegenerative conditions.

	Researchers look to CNVs to better understand human ethnic diversity (Phys.org)—A large team of international researchers has undertaken a study to better understand the genetic mechanism behind ethnic diversity. In their paper published in the journal Science, the team describes their study, their results and their plans for the future.
	Model demonstrates link between species' traits, competitive success, environmental conditions Researchers at Yale University and the University of Georgia have developed and experimentally tested a new mathematical model that helps explain when and where species are likely to outcompete or coexist with one another. The results, just published in Proceedings of the Royal Society B, are a first step toward understanding how changing environmental conditions may affect species distributions.
	Climate change causes timing shifts in fish reproduction Research by Rebecca Asch, a recent graduate of Scripps Institution of Oceanography at UC San Diego, shows a strong correlation between warmer ocean temperatures and changes in the timing of fish reproduction.
	Switching mouse neural stem cells to a primate-like behavior When the right gene is expressed in the right manner in the right population of stem cells, the developing mouse brain can exhibit primate-like features. In a paper publishing August 7th in the Open Access journal PLOS Biology, researchers at the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) succeeded in mimicking the sustained expression of the transcription factor Pax6 as seen in the developing human brain, in mouse cortical progenitor cells. This altered the behavior of these cells to one that is akin to that of progenitors in the developing primate neocortex. Consequently, the mouse progenitors generated more neurons - a prerequisite for a bigger brain.
	How yeast doubled its genome—by mating between species The common baker's yeast (Saccharomyces cerevisiae) is used to make bread, wine and beer, and is the laboratory workhorse for a substantial proportion of research into molecular and cell biology. It was also the first non-bacterial living thing to have its genome sequenced, back in 1996. However, when the sequence of that genome emerged it appeared that the scientists were seeing double - the organism seemed to have two very different versions of many of its genes. How could this have happened?
	Linking cell-population to whole-fish growth Every year, more than a million fish are used for toxicity testing and scientific research in the EU alone, and around 400 fish are needed for a single fish early-life stage test. Such toxicity tests are often required by regulatory authorities for new chemical substances, as fish are particularly sensitive to contaminants in water at early developmental stages. However, the increasing use of experimental animals is ethically questionable. In addition, conventional tests are complex, expensive and take weeks or months to complete. Alternative approaches are therefore being sought by scientists, regulators and industry. A promising new method has now been demonstrated by an Eawag study, conducted in collaboration with the ETH, the EPFL and the University of York (UK).
	Pupil shape linked to animals' ecological niche While the eyes may be a window into one's soul, new research led by scientists at the University of California, Berkeley, suggests that the pupils could also reveal whether one is a hunter or hunted.
	Mutations linked to genetic disorders shed light on a crucial DNA repair pathway Dividing cells are prone to errors, and so they must be prepared to summon sophisticated emergency systems to deal with potential damage. One type of division-derailing mishap can occur when assault by certain chemicals causes two strands of DNA to permanently connect when they shouldn't, in what scientists call interstrand crosslinks (ICLs). Properly fixing these crosslinks is crucial to preventing cancer, maintaining tissues, and fertility.
	Land animals proliferate faster than aquatic counterparts Of the nearly 1.5 million known animal species on Earth, those with backbones come in a stunning array of shapes and sizes. Vertebrates include fish, amphibians, reptiles, birds and mammals, and the number of species within these groups can vary wildly. For example, there are only six species of lungfish and only 25 crocodilians—but roughly 10,000 birds and 9,700 lizards and snakes.
	Giant spider webs make another appearance in Dallas area While traveling down CA Roan Drive in Rowlett recently, people have been exposed to an "eerie" sight on a number of trees lining that route, said Mike Merchant, Texas A&M AgriLife Extension Service urban entomologist in Dallas.
	A model for ageing Life is short, especially for the killifish, Nothobranchius furzeri: It lives for only a few months and then its time is up. During that short lifespan it passes through every phase of life from larva to venerable old fish. Its brief life expectancy – unusual for a vertebrate – has long fascinated Dario Valenzano of the Max Planck Institute for Biology of Ageing in Cologne. During a ten-year period he has made it a model organism for research into ageing.
	Giraffes aren't dangerous – but they will soon be endangered An American trophy hunter has kicked off another social media furore after defending a recent giraffe kill in South Africa by claiming they were "very dangerous animals". In one sense she is right – giraffes are big and strong and you certainly wouldn't want one kicking you. But attacks on humans are very rare.
	Different tools to deal with medfly pest Research has revealed a management technique involving sterilising the Mediterranean fruit fly (Ceratitis capitata) is a more cost effective alternative of eradicating the pest in the face of a looming pesticide ban.
	Gene splicing in lice and the challenge of clothing A terrific article recently published in Molecular Biology and Evolution, "Alternative Splice in Alternative Lice," provides a compelling example of maximizing genome information – adaptation of the louse Pediculus humanus to the new habitat created when our ancestors invented clothing.
	GPS transmitters can protect animals from poaching The killing of the lion Cecil in a national park in Zimbabwe by a big-game hunter has sparked worldwide outrage. Researchers at the University of Oxford had outfitted Cecil with a GPS collar to monitor his behaviour. It was only thanks to this special tag that the cause of the animal's death was cleared up. At the Max Planck Institute for Ornithology in Radolfzell, scientists also use transmitters to observe the behavior of different species of animals. The data collected through telemetry is so accurate that it can help to quickly locate killed animals and clear up their cause of death. From 2016, the satellite-based system Icarus will also capture the global movement patterns of animals. Icarus will thus significantly improve the protection of endangered species.

	New breakthrough in the molecular characterization of acute myeloid leukemia The multidisciplinary team comprising the Leucégène research group, a major project headed by Dr. Guy Sauvageau of the Institute for Research in Immunology and Cancer (IRIC) at the Université de Montréal and Dr. Josée Hébert of Maisonneuve-Rosemont Hospital (MRH), has just published a series of important observations on the genetic and molecular characteristics of two leukemia subtypes in the prestigious journal Nature Genetics. The results of the study also suggest the possibility of a new combinatorial therapeutic approach for certain leukemias. The goal of the Leucégène project is to develop new tools for a more detailed classification of patients suffering from acute myeloid leukemia (AML) with a view to improving outcomes and more effectively guiding the choice of available treatment options. AML is a highly aggressive blood cancer that kills close to 1,000 people a year in Canada. Because this is a very complex cance! r, current prognostic tests are imprecise in assessing risks and treatment choices in most patients.
