Nanotechnology news

	Researchers publish new synthesis technique for developing nanostructured materials Researchers at Illinois Tech recently unveiled a major breakthrough in nanotechnology processing that reduces the time, and increases the amount of product that can be manufactured on an industrial scale. The new technique makes nanotechnology economically viable for numerous applications, including pollution control for vehicles, reduction in waste heat from vehicles and electronics, and removal of toxic waste from water.
	Researchers resolve a problem that has been holding back a technological revolution Imagine an electronic newspaper that you could roll up and spill your coffee on, even as it updated itself before your eyes.
	Quantum dots with impermeable shell: A powerful tool for nanoengineering Unique optical features of quantum dots make them an attractive tool for many applications, from cutting-edge displays to medical imaging. Physical, chemical or biological properties of quantum dots must, however, be adapted for specific applications. Unfortunately, quantum dots prepared by chemical methods using copper-based click reactions destroy the ability of quantum dots to emit light. Russian scientists have shown, however, that zinc oxide (ZnO) quantum dots prepared by a new method, after modification by the click reaction via copper ions, fully retain their ability to emit light.
	'Sniffer plasmons' could detect explosives Physicists from the Moscow Institute of Physics and Technology (MIPT) have found that graphene might be the ideal material for manufacturing plasmonic devices capable of detecting explosive materials, toxic chemicals, and other organic compounds based on a single molecule, according to an article published in Physical Review B.
	Does ecology reach all the way down to the subatomic scale? Imagine you could stop being human-sized for a while and shrink down to the size of a bacterium, roughly one-millionth of your current stature. At this scale, you would stop being bound by gravity and instead discover that viscosity is the dominant factor, making the air feel more like swimming through a gloopy swamp.
	Down to the wire: Researchers and new bacteria Scientists sponsored by the Office of Naval Research (ONR) have genetically modified a common soil bacteria to create electrical wires that not only conduct electricity, but are thousands of times thinner than a human hair.

Physics news

	Physicist claims to have observed quantum effects of Hawking radiation in the lab for the first time (Phys.org)—Jeff Steinhauer, a physicist at the Israel Institute of Technology, has published a paper in the journal Nature Physics describing experiments in which he attempted to create a virtual black hole in the lab in order to prove that Stephen Hawking's theory of radiation emanating from black holes is correct —though his experiments are based on sound, rather than light. In his paper, he claims to have observed the quantum effects of Hawking radiation in his lab as part of a virtual black hole—which, if proven to be true, will be the first time it has ever been achieved.
Hexagonal boron nitride semiconductors enable cost-effective detection of neutron signals One of the most critical issues the United States faces today is preventing terrorists from smuggling nuclear weapons into its ports. To this end, the U.S. Security and Accountability for Every Port Act mandates that all overseas cargo containers be scanned for possible nuclear materials or weapons.
	Studying blood flow dynamics to identify the heart of vessel failure When plaque, fatty deposits that build up on the inside of arteries, rupture and block blood flow, the results can be deadly. Such hardening of the arteries, also called atherosclerosis, typically leads to heart disease, the leading cause of death in the United States. Despite years of therapeutic advances, scientists are still figuring out how and why these deposits develop, searching for a way to reduce the number of heart attacks and strokes.
	Spin polarization by strong field ionization Strong field ionization has been studied for over half a century. Yet, the role of electron spin during this process has been largely overlooked. Surprisingly, our joint experimental and theoretical study shows that a chance of detaching spin-up or spin-down electron from an atom can be very different.
	Physicists to enhance accuracy of the world's most powerful synchrotron According to the head of the TPU researcher Alexander Potylitsyn at the Department of Applied Physics, X-ray and laser radiation are commonly used in modern medicine, but separately from each other. X-rays allow doctors to superficially scan the patient's body. However, it is impossible to see inside a specific biological object, for example, blood vessels near the heart. The problem of medical X-ray sources is related to their scattering processes inside structures; therefore, only a small amount of energy reaches the targeted area of the body, significantly reducing diagnostic capabilities. By contrast, laser light comprises a focused energy flow that is not dissipated. But lasers can't penetrate structures thicker than 30 cm, and because this radiation is high temperature, there is a danger of damage to human body tissues.
	Scientists produce microresonators with unprecedented precision Researchers from Aston University and ITMO University demonstrated a new method to fabricate optical microresonators with unprecedented precision of less than the diameter of a single hydrogen atom and 100 times less than the current fabrication precision of similar devices. The possibility of creating microresonators with this precision can enable the development of more complex optical circuits and possibly allow engineers to use light for long-term information storage.
	How to create sounds that only you can hear in a venue Picture your typical busy cafe or restaurant that's full of people. The diners are usually all forced to listen to the same music that's pumped into the venue via the speakers.
	New 3-D thermal imaging capability for satellites Scientists from the National Physical Laboratory (NPL) have developed a new technique for taking 3D thermal images of satellites. The technique is being developed for prospective use at the European Space Agency's (ESA) largest vacuum facility, the Large Space Simulator (LSS). The measurements will better allow measurement data to be compared with thermal models, verifying their accuracy.
	Dusty plasma in the universe and in the laboratory In 1981, the Voyager 2 space probe took intriguing images of Saturn's rings as it passed by the giant planet on its way to Uranus.
	Cosmology: Lore of lonely regions A research group led by Ludwig-Maximilians-Unversitaet (LMU) in Munich physicist Nico Hamaus is calculating the dynamics of cosmic voids and deriving new insights into our entire universe.

Earth news

	New Antarctic ice discovery aids future climate predictions A team of British climate scientists comparing today's environment with the warm period before the last ice age has discovered a 65% reduction of Antarctic sea ice around 128,000 years ago. The finding is an important contribution towards the challenge of making robust predictions about the Earth's future climate.
	Companies can reduce carbon footprint by giving consumers green choices Companies can reduce the carbon footprint of their supply chains and improve customer satisfaction by giving consumers information and tools to make green choices, according to research conducted by the Energy Department's National Renewable Energy Laboratory (NREL) and published in the Proceedings of the National Academy of Sciences.
	Sticky organic molecules hop aboard oily floaters and may influence the amount of sunlight reflected by marine clouds Exiting the airport, travelers catch a taxi, Uber, or bus ride to their next stop. Seafaring sugar molecules floating near the ocean's surface take a similar tack. Instead of taxis, they hitch a ride on oily molecules floating by.
	Big fish—and their pee—are key parts of coral reef ecosystems Coral reefs wouldn't be the same without their beautiful fish.
	Melting glaciers pose threat beyond water scarcity: floods The tropical glaciers of South America are dying from soot and rising temperatures, threatening water supplies to communities that have depended on them for centuries. But experts say that the slow process measured in inches of glacial retreat per year also can lead to a sudden, dramatic tragedy.
Female scientists to sample plastics in all five Great Lakes Female scientists from the U.S. and Canada will set sail Aug. 20 on all five Great Lakes and connecting waterways to sample plastic debris pollution and to raise public awareness about the issue.
	Fewer low clouds in the tropics With the help of satellite data, ETH scientists have shown that low-level cloud cover in the tropics thins out as the earth warms. Since this cloud cover has a cooling effect on the climate, the two-degree warming target may therefore be reached earlier than many models have predicted.
Can we economically outgrow climate change damages? Not for hurricanes we can't When hurricanes like Katrina in 2005 or Sandy in 2012 impact on highly populated regions they bring about tremendous damages. More than 50 percent of all weather-related economic losses on the globe are caused by damages due to tropical cyclones. Researchers from the Potsdam Institute for Climate Impact Research (PIK) now analyzed the magnitude of future hurricane losses in relation to economic growth. Showcasing the United States they found that financial losses per hurricane could triple by the end of the century in unmitigated climate change, while annual losses could on average rise by a factor of eight. Most importantly and contrary to prevalent opinion, they conclude that economic growth will not be able to counterbalance the increase in damage.
	Sea ice strongly linked to climate change in past 90 000 years Expansion and retreat of sea ice varied consistently in pace with rapid climate changes through past 90,000 years, a new study in Nature Communications shows.
Technique for cheaper shale oil extraction Researchers at the Moscow Institute of Physics and Technology (MIPT) have developed mathematical models and software enabling Russian shale oil producers to reduce development costs. Multiple hydraulic fracturing (aka hydrofracking) is a standard shale oil extraction technique. It involves the high-pressure injection of fluid into a horizontal borehole. The fluid used is typically water with sand or other specially designed additives (called proppants). The rock formation is first fractured by water, allowing oil to flow freely into the borehole. When the pressure is released, the fractures are held open by the proppant. This speeds up oil extraction and increases production output. However, this technique relies on preliminary calculations; if these are ignored, enormous financial losses could result.
	NASA sees wind shear affecting Tropical Storm Chanthu Visible imagery from NASA's Aqua satellite showed wind shear was affecting Tropical Storm Chanthu as it moved parallel to the big island of Japan early on Aug. 16. Chanthu is expected to make landfall and move north over the island of Hokkaido.

In their paper published in the Astronomical Journal, William Bottke and David Nesvorný with Southwest Research Institute in Boulder Colorado and David Vokrouhlický with Charles University in the Czech Republic outline their reasons for believing the meteorite did not come from the asteroid, but from much farther out.
	An ancient Mayan Copernicus For more than 120 years the Venus Table of the Dresden Codex—an ancient Mayan book containing astronomical data—has been of great interest to scholars around the world. The accuracy of its observations, especially the calculation of a kind of 'leap year' in the Mayan Calendar, was deemed an impressive curiosity used primarily for astrology.
	Pulsar-based spacecraft navigation system one step closer to reality Pulsars are highly magnetized, rotating neutron stars that emit electromagnetic radiation at regular intervals. They are often dubbed "lighthouses" of the universe as their emission is beamed; thus, the pulse of radiation is seen only each time the beam sweeps across the line of sight. A spacecraft navigation method known as XNAV, based on X-ray signals emitted from pulsars, has recently taken a leap forward, thanks to a study conducted by U.K. scientists from the National Physical Laboratory (NPL) and the University of Leicester.

	Scientists 'teach' hydrogen to penetrate in metal surfaces through oxidate layers Oxidate layers on metal surfaces are a barrier for hydrogen penetration in and out of metal. In experiments conducted at the Plasma Physics Department at MEPhI , it has been shown that hydrogen penetration through oxidate layers can be manipulated through radiation of surface oxide by atomic and ion flows. In particular, hydrogen penetration through the surface and its capture by metals accelerates under the radiation of the oxidate surface by hydrogen atoms or hydrogen plasma with thermal velocity. If a surface radiating ion or atomic flow has an oxygen admixture, hydrogen removal from metal takes place. This phenomenon has been called "radiation enhanced penetration" (REP).

	We've been wrong about the origins of life for 90 years For nearly nine decades, science's favorite explanation for the origin of life has been the "primordial soup". This is the idea that life began from a series of chemical reactions in a warm pond on Earth's surface, triggered by an external energy source such as lightning strike or ultraviolet (UV) light. But recent research adds weight to an alternative idea, that life arose deep in the ocean within warm, rocky structures called hydrothermal vents.
	Researchers discover the hidden potential of disordered proteins Prostate cancer, Alzheimer's, Parkinson's...these three diseases are associated with proteins that share a common feature, namely disordered regions that have no apparent rigid three-dimensional structure.

	Soybean science blooms with supercomputers Knowledge of the soybean in the U.S. has come a long way since its humble start, namely as seeds smuggled by ship from China in the 1700s. A sanction back then from emperor Qianlong prevented trade outside of Canton. Undeterred, a former seaman with the East India Trading Company named Samuel Bowen first brought soybeans to Savannah, Georgia, in 1765. A couple of years later Bowen filed a patent for a new way of making sago (a starchy cake), vermicelli (noodles), and soy sauce from soybeans. Soybeans on colonial soil also got noticed by Benjamin Franklin, who wrote of their universal use in China as a cheese, which we now call tofu.

	New cancer type with PIK3CA mutations A newly defined type of colorectal and endometrial cancer involves at least two somatic mutations in the mismatch repair genes (MMR): MLH1, MSH2, MSH6, PMS2. This double somatic MMR cancer has no germline mutations in the MMR genes, unlike tumors due to hereditary Lynch syndrome. Double somatic MMR cases, along with Lynch syndrome and MLH1 gene hypermethylation cases, exhibit microsatellite instability (MSI). This hypermutable phenotype is caused by the loss of DNA mismatch repair activity.
New guidance for administering hemorrhage prevention treatment Tranexamic acid (TXA) is currently being administered to injured patients by many prehospital air and ground systems, despite a lack of evidence supporting or refuting its efficacy in preventing hemorrhage.

	Old church records help assess the impact of childhood disease and why people live longer The Great Exhibition of 1851, housed in London's Crystal Palace, showcased the newest of culture and science – including the world's largest diamond, a precursor to the fax machine and barometer which worked entirely through leeches. Living conditions were tough, but having survived to the age of 20, a young Londoner attending the exhibition could expect to live until around 60. A century and a half later, 20-year-old Londoners watching the Olympics down the pub can expect to live to the age of 80.
	How your body clock determines whether you'll get ill or not From vitamin C and echinacea to warm clothes and antibacterial soap, there's no shortage of ideas about how to prevent and manage colds and flu. Unfortunately, many of these are not based on solid scientific evidence. In fact, medical researchers are only starting to unravel the range of factors that affect our susceptibility to getting an infection. Now we have discovered that our body clock plays an important role – making us more prone to get infected at certain times of the day.
Professor pursues approach to diabetes that makes daily injections obsolete Unlike type 2 diabetes, type 1 diabetes often afflicts the young with an indifference to lifestyle and dietary habits. It begins when the immune system attacks the insulin-producing cells in the pancreas. Insulin is necessary for balancing blood sugar levels, and it allows the body to use these sugars for energy or store glucose for future use. Without this hormone, blood sugar levels will skyrocket, leading to severe health problems and even death.
Washington's foster children experience 'justice by geography,' report finds A new report from The Access to Counsel Project at the UW School of Law sheds light on how inconsistent practices and policies in Washington state dependency (child abuse and neglect) courts leave many children without an advocate in decisions that shape every aspect of their lives.

	Molecule prevents effect of chemotherapy Annually about 2000 Danish patients with colorectal cancer are treated with chemotherapy. Today, a range of different chemotherapeutic regimens are available. However, deciding which regimen to use is not easy. Unfortunately, it is currently impossible to predict which regimen will be most beneficial for the individual patient and for a large number of patients their cancer cells are actually resistant to the chosen treatment. Roughly half of the treated patients do not benefit from their first-line treatment - the cancer cells are not killed - and the patients sometimes only experience the serious side effects of the treatment.

Steroid treatment in very low birth weight infants may contribute to vision problems Because of the beneficial effect of corticosteroids on lung function, especially in infants who are ventilator dependent, corticosteroids are, at times, administered to very low birth weight neonates to treat established or evolving lung disease. However, it has long been suspected that steroids may have negative neurodevelopmental effects on very premature infants. In a study in the Journal of the American Association for Pediatric Ophthalmology and Strabismus (AAPOS), researchers found that for very premature infants with birth weights of less than 500 grams, there was a 1.6 times increased risk for retinopathy of prematurity (ROP) and a 1.7 times greater chance for advanced ROP.
	Researchers identify key elements of cellular response to proteasome dysfunction Maintaining appropriate levels of proteins within cells largely relies on a cellular component called the proteasome, which degrades unneeded or defective proteins to recycle the components for the eventual assembly of new proteins. Deficient proteasome function can lead to a buildup of unneeded and potentially toxic proteins, so cells usually respond to proteasome dysfunction by increasing production of its component parts. Now two Massachusetts General Hospital (MGH) investigators have identified key molecules in the pathway by which cells in the C. elegans roundworm sense proteasome dysfunction, findings that may have application to treatment of several human diseases.
Most physicians recognize shaken baby syndrome as a medical diagnosis A University of Colorado School of Medicine researcher and colleagues have conducted the first-ever survey of physicians on the validity of "abusive head trauma" as a medical diagnosis.

Study details sources of discrepancies between initial and final pathology reports When should a surgeon stop cutting? The answer can depend on whether a patient's tissue does or does not contain cancer cells. This is the kind of question answered by a technique known as "intraoperative consultation by frozen section" - basically, a surgeon removes a small tissue sample, which is frozen and sent to a hospital's pathology department for lightning-fast analysis. A pathologist examines the tissue and returns an answer to the surgeon, who may base surgery decisions on the results. In addition to this intraoperative consultation, part of the tissue sample is "fixed" for a more measured analysis, resulting in a final evaluation about 24 hours later.
Bone marrow-derived stem cells offer blood transplant patients better quality of life A large, nationwide study published in the journal JAMA Oncology found that people who received transplants of cells collected from a donor's bone marrow the original source for blood stem cell transplants, developed decades ago had better self-reported psychological well-being, experienced fewer symptoms of a common post-transplant side effect called graft-vs.-host disease and were more likely to be back at work five years after transplantation than those whose transplanted cells were taken from the donor's bloodstream.
