Nanotechnology news

	United States, China team explore energy harvesting Six authors have described their work in harvesting energy in a paper titled "Ultrathin, Rollable, Paper-Based Triboelectric Nanogenerator for Acoustic Energy Harvesting and Self-Powered Sound Recording." Translation: A paper microphone may help charge your cellphone. Jacob Aron in New Scientist wrote about their work; he said one benefit of such a microphone is that it could harvest acoustic energy to top up a phone charge on the go. The team, from the Georgia Institute of Technology in the U.S. and Chongqing University and Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, China, published their paper in ACS Nano last month.
	Happily ever after: Scientists arrange protein-nanoparticle marriage Fastening protein-based medical treatments to nanoparticles isn't easy. With arduous chemistry, scientists can do it. But like a doomed marriage, the fragile binding that holds them together often separates.
	Researchers succeed in light-controlled molecule switching Scientists at the University of Konstanz and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are working on storing and processing information on the level of single molecules to create the smallest possible components that will combine autonomously to form a circuit. As recently reported in the academic journal Advanced Science, the researchers can switch on the current flow through a single molecule for the first time with the help of light.
VTT creates efficient method of producing metallic nanoparticles VTT Technical Research Centre of Finland Ltd has developed a new, cost-efficient method of producing various types of metallic nanoparticles. Nanoparticles can be used in applications such as conductive and magnetic inks, medical diagnostics and drug dosing, tailoring the electrical and magnetic properties of polymers and energy technology. VTT is seeking a party interested in commercialising the technique.
	Researchers establish theoretical framework for graphene physics Since the discovery of graphene about a decade ago, scientists have been studying ways to engineer electronic band gaps in the material to produce semiconductors which can create new electronic devices. A team of researchers from Yale-NUS College, the Center for Advanced 2D Materials and Department of Physics at the National University of Singapore (NUS) and the University of Texas at Austin (UT Austin) have established a theoretical framework to understand the elastic and electronic properties of graphene. The findings were published in February 2015 in Nature Communications.

Physics news

	Quantum model helps solve mysteries of water Water is one of the most common and extensively studied substances on earth. It is vital for all known forms of life but its unique behaviour has yet to be explained in terms of the properties of individual molecules.
	Liquid crystal bubbles experiment arrives at International Space Station An experiment led by the University of Colorado Boulder arrived at the International Space Station today and will look into the fluid dynamics of liquid crystals that may lead to benefits both on Earth and in space.

Earth news

	Mountain of electrical waste reaches new peak A record amount of electrical and electronic waste hit the rubbish tips in 2014, with the biggest per-capita tallies in countries that pride themselves on environmental consciousness, a report said Sunday.
	Source of Earth's ringing? French team views ocean waves Three researchers in France have authored "How ocean waves rock the Earth: Two mechanisms explain microseisms with periods 3 to 300 s," published in Geophysical Research Letters, a journal of the American Geophysical Union (AGU). The paper attempts to explain the source of Earth's ringing sound.
	Study shines new light on the source of diamonds A team of specialists from four Australian universities, including the University of Western Australia, has established the exact source of a diamond-bearing rock for the first time.
	Ocean currents impact methane consumption Large amounts of methane - whether as free gas or as solid gas hydrates - can be found in the sea floor along the ocean shores. When the hydrates dissolve or when the gas finds pathways in the sea floor to ascend, the methane can be released into the water and rise to the surface. Once emitted into the atmosphere, it acts as a very potent greenhouse gas twenty times stronger than carbon dioxide. Fortunately, marine bacteria exist that consume part of the methane before it reaches the water surface. Geomicrobiologists and oceanographers from Switzerland, Germany, Great Britain and the U.S. were able to show in an interdisciplinary study that ocean currents can have a strong impact on this bacterial methane removal. Nature Geoscience has published the study today.
	Uranium isotopes carry the fingerprint of ancient bacterial activity The oceans and other water bodies contain billions of tons of dissolved uranium. Over the planet's history, some of this uranium was transformed into an insoluble form, causing it to precipitate and accumulate in sediments. There are two ways that uranium can go from a soluble to an insoluble form: either through the action of live organisms - bacteria - or by interacting chemically with certain minerals. Knowing which pathway was taken can provide valuable insight into the evolution and activity of microbial biology over Earth's history.
	Necessity at the roots of innovation: The scramble for nutrients intensifies as soils age Confronted by extreme scarcity of nutrients in an Australian dune ecosystem, the leaves of different plant species converge on a single efficient strategy to conserve phosphorus, an essential nutrient. But it is a different story underground, say researchers, including Ben Turner, staff scientist at the Smithsonian Tropical Research Institute. Plants on older dunes draw from a full bag of tricks, and take advantage of nearly all of the known adaptations for acquiring nutrients to capture the phosphorus they need.
	Soil nutrients may limit ability of plants to slow climate change Many scientists assume that the growing level of carbon dioxide in the atmosphere will accelerate plant growth. However, a new study co-written by University of Montana researchers suggests much of this growth will be curtailed by limited soil nutrients.
	Canada revises upward CO2 emission data since 1990 Canada revised its greenhouse gas emission data from 1990 to 2013 in a report Friday, showing it had higher carbon dioxide discharges each year, and a doubling of emissions from its oil sands.
	China's struggle for water security Way back in 1999, before he became China's prime minister, Wen Jiabao warned that water scarcity posed one of the greatest threats to the "survival of the nation".
	5 years after BP spill, drillers push into riskier depths Five years after the nation's worst offshore oil spill, the industry is working on drilling even further into the risky depths beneath the Gulf of Mexico to tap massive deposits once thought unreachable. Opening this new frontier, miles below the bottom of the Gulf, requires engineering feats far beyond those used at BP's much shallower Macondo well.
Israeli port city closes 5 factories over cancer fears The mayor of Haifa, Israel's third largest city, ordered Sunday the closure of five petrochemical plants following a health ministry warning linking high cancer rates to air pollution.
Impacts of Deepwater Horizon oil spill to marine organisms on the Gulf Coast On April 20, 2010, an explosion on the Deepwater Horizon (DWH) rig caused a release of 200 million gallons of oil into the Gulf of Mexico before the well was capped on July 15, 2010. Close to 100,000 kilometers, including more than 1,000 total linear miles of coastlines in Louisiana, Alabama, Mississippi and Florida were affected. A number of methods were used to prevent the oil from reaching the shoreline, including an estimated 1.9 million gallons of dispersant. Dispersants are one of the most controversial of these methods and are typically used when other methods are not adequate.
	Comparing climate models to real world shows differences in precipitation intensity Precipitation is difficult to represent in global climate models. Although most single-column models can reproduce the observed average precipitation reasonably well, there are significant differences in their details, including mean precipitation intensity. Scientists evaluated the performance of seven single-column models, used by global models to complex processes, by comparing simulated surface precipitation with observations.
	Study shows seafood samples had no elevated contaminant levels from oil spill A sampling of more than 1,000 Gulf of Mexico fish, shrimp, oysters and blue crabs taken from Cedar Key, Fla., to Mobile Bay, Ala., between 2011 to 2013, shows no elevated contaminant levels, according to a seafood safety study conducted by Dr. Andrew Kane and colleagues at the University of Florida. In fact, some 74 percent of the seafood tested showed no quantifiable levels of oil contaminants at all.
	Team studies intricacies of marine snow formation in the Gulf of Mexico following Deepwater Horizon oil spill Five years ago today, the Deepwater Horizon (DWH) oil rig exploded in the Gulf of Mexico. Since then, scientists have continued to study the effects of the largest environmental disaster in the history of the petroleum industry.
	Obama says 'no greater threat to planet than climate change' US President Barack Obama said Saturday that climate change poses the world's biggest single threat.
	Sharing knowledge for the sustainable and safe use of chemicals HEROIC researchers have developed a roadmap towards the sustainable and safe use of chemicals, combining environmental and human risk assessments.
	How radiative fluxes are affected by cloud and particle characteristics To understand how the Earth will change as emissions from fossil fuel combustion change, climate models calculate a complex and changing mix of clouds and emissions that interact with solar energy. To narrow the range of possible answers from these calculations in the Community Atmosphere Model version 5 (CAM5), researchers analyzed the effect of 16 parameters, proven numerical stand-ins for atmospheric processes, on the flux of energy at the top of the atmosphere. They found that the flux of energy entering and exiting the top of the atmosphere is the main driver of surface temperature change.
	As US assumes Arctic Council chairmanship, new report emphasizes cooperation over conflict Although the media often portray the Arctic as a new "Great Game" ripe for conflict, a group of international Arctic experts co-chaired by Dartmouth College released recommendations today aimed at preserving the polar north as an area for political and military cooperation, sustainable development and scientific research.
Nuclear waste drums appear stable after signs of reactions Federal officials say dozens of drums of radioactive waste at one of the nation's premier weapons laboratories are stable after some showed signs of chemical reactions over the past year.

Astronomy & Space news

	Cold cosmic mystery solved: Largest known structure in the universe leaves its imprint on CMB radiation In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.
	Astronomers probe inner region of young star and its planets Astronomers have probed deeper than before into a planetary system 130 light-years from Earth. The observations mark the first results of a new exoplanet survey called LEECH (LBT Exozodi Exoplanet Common Hunt), and are published today in the journal Astronomy and Astrophysics.
	Pulsing light may indicate supermassive black hole merger As two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a "binary," or two black holes in such close orbit they are gravitationally bound to one another. In a new study, astronomers at the University of Maryland present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries.
	Dawn glimpses Ceres' north pole After spending more than a month in orbit on the dark side of dwarf planet Ceres, NASA's Dawn spacecraft has captured several views of the sunlit north pole of this intriguing world. These images were taken on April 10 from a distance of 21,000 miles (33,000 kilometers), and they represent the highest-resolution views of Ceres to date.

	Cosmologically complicating dust The universe was created 13.7 billion years ago in a blaze of light: the big bang. Roughly 380,000 years later, after matter (mostly hydrogen) had cooled enough for neutral atoms to form, light was able to traverse space freely. That light, the cosmic microwave background radiation (CMBR), comes to us from every direction in the sky uniformly ... or so it first seemed. In the last decades, astronomers discovered that the radiation actually has very faint ripples and bumps in it at a level of brightness of only a part in one hundred thousand – the seeds for future structures, like galaxies.
	Curiosity rover making tracks and observations NASA's Curiosity Mars rover is continuing science observations while on the move this month. On April 16, the mission passed 10 kilometers (6.214 miles) of total driving since its 2012 landing, including about a fifth of a mile (310 meters) so far this month.

Chemistry news

	Plausibility of the vibrational theory of smell The vibrational theory of olfaction explains several aspects of odorant detection that theories based purely on receptor binding do not. It provides for additional selectivity through receptors that are tuned to specific vibrational bands of the odorants they bind, and also through the subsequent conduction of electrons across the odorant, presumably by a tunneling mechanism. A lot of people seem like the theory, or at least its main theorist, Luca Turin. Over the years, efforts to prove, or disprove the vibrational theory have progressed through a long series of olfactory touchstones: molecular enigmas like carvone, acetophenone, or benzaldehyde, whose experimentally perceived scent is a seemingly fickle amalgam of various molecular vibrations, mirror images, and isotopes.

Electron transfer challenges common fluorescence technique Tryptophan is an amino acid, one of the building blocks of proteins. It is used extensively to study how proteins change their 3D structure, and also how they interact with other proteins and molecules. This is studied with a fluorescence technique called FRET, which measures the transfer of energy from tryptophan to another molecule. But in some cases, FRET data could be distorted because tryptophan transfers an electron instead of energy. Using a unique spectroscopic technique, scientists at EPFL have now confirmed for the first time that this is indeed the case. The study, which has far-reaching implications for the effectiveness of FRET, is published in PNAS.

Research highlights the importance of 'self-DNA' for maintaining diversity among species In natural plant communities, diversity is maintained by limits set on each plant by itself. This involves a detrimental effect of self-DNA (DNA from the same species released during decomposition) on the plant's and its offspring's growth. New research finds that this process not only regulates plant populations but may also be generalized to a range of additional organisms including algae, protozoa, fungi, and animals.

	Pancreatic cancer loses viral defenses when talking with supporting cells Ottawa researchers have unlocked a way to make pancreatic cancer cells more vulnerable to cancer-killing viruses, known as oncolytic viruses. Outlined in a paper published today by Nature Medicine, the scientists have discovered how they can exploit the communication, or cross-talk, between pancreatic cancer and a specific cell type that supports the tumour. They found that this cross-talk weakens the ability of both cell types to fight off cancer-fighting viruses.
	Pancreatic cancer breakthrough: Scientists turn cancer cells into normal cells A new research study has shown that pancreatic cancer cells can be coaxed to revert back toward normal cells by introducing a protein called E47.

	Gene signatures predict doxorubicin response in K9 osteosarcoma There are two chemotherapies commonly used to treat bone cancer in dogs: doxorubicin and carboplatin. Some dogs respond better to one drug than to the other. But until now, the choice has been left largely to chance. New work by University of Colorado Cancer Center members at Colorado State University Flint Animal Cancer Center presented today at the American Association for Cancer Research (AACR) Annual Meeting 2015 demonstrates a gene expression model that predicts canine osteosarcoma response to doxorubicin, potentially allowing veterinary oncologists to better choose which drug to use with their patients. The approach is adopted from and further validates a model known as COXEN (CO-eXpression gEne aNalysis), developed at the CU Cancer Center by center director Dan Theodorescu, MD, PhD, which is currently in clinical trials to predict the response of human tumors to drugs.
New combo of immunotherapy drugs is safe, shrinks tumors in metastatic melanoma patients Once again, researchers at Penn's Abramson Cancer Center have extended the reach of the immune system in the fight against metastatic melanoma, this time by combining the checkpoint inhibitor tremelimumab with an anti-CD40 monoclonal antibody drug. The first-of-its-kind study found the dual treatments to be safe and elicit a clinical response in patients, according to new results from a phase I trial to be presented at the AACR Annual Meeting 2015 on Sunday, April 19.
Driver of non-small cell lung cancer, FGFR1, also in 23 percent of small cell lung cancer Significant new treatments are available or in clinical trials for non-small cell lung cancer. The same explosion in treatment options is not true for the disease's cousin, small cell lung cancer, the less common and more aggressive form of the disease. Results presented by the University of Colorado Cancer Center at the American Association for Cancer Research Annual Meeting 2015 show the presence of a known driver of non-small cell lung cancer in small cell lung cancer, implying that promising treatments in development for the first may be applicable to the second form of the disease as well.
Leading doctors warn that sepsis deaths will not be curbed without radical rethink of research strategy Leading doctors today [Monday 20 April, 2015] warn that medical and public recognition of sepsis—thought to contribute to between a third and a half of all hospital deaths—must improve if the number of deaths from this common and potentially life-threatening condition are to fall.
Animal study shows why long-time consumption of soyfoods reduces breast cancer recurrence Women diagnosed with breast cancer are often told not to eat soyfoods or soy-based supplements because they can interfere with anti-estrogen treatment. But new research being presented at the American Association for Cancer Research (AACR) Annual Meeting 2015 could eventually impact that advice, because in animals, a long history of eating soyfoods boosts the immune response against breast tumors, reducing cancer recurrence.
Immunotherapy drug pembrolizumab shows promise for mesothelioma patients The PD-1 inhibitor pembrolizumab, a cancer immunotherapy drug, shrank or halted growth of tumors in 76 percent of patients with pleural mesothelioma, a rare and deadly form of cancer that arises in the outer lining of the lungs and internal chest wall, according to a new study from researchers in the Perelman School of Medicine at the University of Pennsylvania. Patients diagnosed with the disease, which is tied to exposure to asbestos, have a median survival rate of about one year.

	Successfully managing fatigue in people with multiple sclerosis Fatigue is one of the most commonly reported and debilitating symptoms of multiple sclerosis (MS) and can significantly reduce an individual's quality of life. Unlike the tiredness that we all experience sometimes, fatigue in those with MS can have a hugely negative impact – it can limit or stop people from doing day-to-day activities and things that really matter to them. It is the main reason why people with MS stop working. Research undertaken at Bournemouth University (BU) has been tackling the challenge of managing fatigue in people with MS, with encouraging results.

Reduction in opioid prescribing, overdoses associated with pharma industry changes Results of a new study led by Boston Medical Center (BMC) researchers, in collaboration with Harvard Medical School (HMS), indicate that the introduction of abuse-deterrent OxyContin, coupled with the removal of propoxyphene from the US prescription marketplace, may have played a role in decreasing opioid prescribing and overdoses. The findings, published in JAMA Internal Medicine, showed that these two changes led to a 19 percent drop in prescription opioid supply that was mirrored by a 20 percent drop in prescription opioid overdose between August 2010 and December 2012. The drop in prescription opioid overdose was partially offset by an increase in overdose due to heroin, an illicit opioid.
	Two tested approaches to treating childhood obesity appear effective A MassGeneral Hospital for Children (MGHfC) study comparing two protocols for the treatment of childhood obesity finds that both were successful in limiting one-year weight gain in obese children. Both interventions, described in a paper published in the April 20 issue of JAMA Pediatrics, combine use of information technology to provide clinicians with the most up-to-date guidelines for the management of obesity in children with tools designed to help families manage behaviors related to obesity and fitness.
Fake malaria drugs not as common as previously reported A rigorous analysis of antimalarial drug quality conducted in Cambodia and Tanzania found no evidence of fake medicines, according to new research published in the American Journal of Tropical Medicine and Hygiene.
Global pandemic of fake medicines poses urgent risk, scientists say Poor quality medicines are a real and urgent threat that could undermine decades of successful efforts to combat HIV/AIDS, malaria and tuberculosis, according to the editors of a collection of journal articles published today. Scientists report up to 41 percent of specimens failed to meet quality standards in global studies of about 17,000 drug samples. Among the collection is an article describing the discovery of falsified and substandard malaria drugs that caused an estimated 122,350 deaths in African children in 2013. Other studies identified poor quality antibiotics, which may harm health and increase antimicrobial resistance. However, new methodologies are being developed to detect problem drugs at the point of purchase and show some promise, scientists say.

	Throwing light on how to conduct a personalized pancreas cancer clinical trial After performing thousands of unsuccessful experiments in his attempt to perfect the light bulb, Thomas Edison famously remarked: "I have not failed, not once. I've discovered ten thousand ways that don't work."
	Cancer gene unintentionally ends the life of cancer cells, turns off life supporting genes Myc cancer gene empowers tumor cells to relentlessly divide but simultaneously, provokes a cell suicide process called apoptosis. Myc controls cells by commanding the expression of every tenth of the genes in the nucleus of a tumor cell. However, in spite of more than two decades of intense research, no Myc motivated killer genes have been found. A team of researchers from the University of Wurzburg, Germany, and the University of Helsinki, Finland, discovered that searching Myc motivated killer genes is akin to barking up the wrong tree. The new findings suggest that Myc makes cancer cells vulnerable to cell death by repressing well-being genes, which are essential for maintaining the life of the cells.
	Pill-taking can be less yucky for kids, study review finds Many sick kids can't or won't swallow pills—and that can make them sicker. But there may be some pretty simple ways to help the medicine go down, a new study says.

	Study suggests new drug strategy for insulin-influenced tumor growth Drugs that target insulin pathways to slow or stop the growth of brain tumors are going in the right direction but appear to be on the wrong track, according to new research at Rice University.
Decreased red blood cell clearance predicts development and worsening of serious diseases Massachusetts General Hospital (MGH) investigators have found the probable mechanism underlying a previously described biomarker associated with the risk of developing serious diseases ranging from cancer to cardiovascular disease and the risk of serious complications. In a paper published in the American Journal of Hematology, the research team reports finding that higher levels of a measure routinely taken as part of the complete blood count - the extent of variation in the size of red blood cells - is caused by reduced clearance of aging cells from the bloodstream. Hundreds of studies since 2007 have found that elevations in this measure - called RDW for RBC (red blood cell) distribution width - predicted the development, progression and risk of death from many conditions.
Long non-coding RNA modulates colorectal cancer metabolism Long non-coding RNAs (lncRNA) are unusual in that they don't encode proteins like normal RNA. Yet they do play a role in regulating cellular functions and interest cancer researchers.
	DNA abnormalities found in children with chronic kidney disease A significant proportion of children with chronic kidney disease (CKD) have unsuspected chromosomal imbalances, including DNA anomalies that have been linked to neurocognitive disorders, according to a new Columbia University Medical Center (CUMC) study.

One test for all infections If you're returning from abroad with a fever, your doctor will likely test you for malaria. You'll give multiple blood samples at the lab, and if the results are inconclusive, you'll face yet another round of tests.
Changes in cancer epigenome implicated in chemotherapy resistance and lymphoma relapse Genomic studies have illuminated the ways in which malfunctioning genes can drive cancer growth while stunting the therapeutic effects of chemotherapy and other treatments. But new findings from Weill Cornell Medical College investigators indicate that these genes are only partly to blame for why treatment that was at one point effective ultimately fails for about 40 percent of patients diagnosed with the most common form of non-Hodgkin Lymphoma.
Extending natalizumab up to 8 weeks shown safe and effective in patients with MS In a study of 1,964 patients with multiple sclerosis (MS) led by researchers at the NYU Langone Multiple Sclerosis Comprehensive Care Center, extending the dose of natalizumab from 4 weeks up to 8 weeks was shown to be well-tolerated and effective in patients, and resulted in no cases of the potentially fatal side effect progressive multifocal leukoencephalopathy (PML).
PTSD common in ICU survivors Post-traumatic stress disorder is often thought of as a symptom of warfare, major catastrophes and assault. It's rarely considered in patients who survive a critical illness and stay in the intensive care unit (ICU). However, in a recent Johns Hopkins study, researchers found that nearly one-quarter of ICU survivors suffer from PTSD. They also identified possible triggers for PTSD and indicated a potential preventive strategy: having patients keep ICU diaries. The findings will be published in the May issue of Critical Care Medicine.

	New signaling pathway discovered in HER2-positive breast cancer, and two powerful drug targets One of the most promising ideas in cancer treatment is to apply a lesson learned in the fight against AIDS (Acquired Immune Deficiency Syndrome): simultaneously attacking a pathological process at different points of weakness can, in some cases, deal a knock-out blow. Just as the so-called AIDS "cocktail" directs multiple agents against multiple targets, so too might future anti-cancer cocktails be directed at multiple, highly specific targets in known cancer pathways. One key in cancer is knowing precisely which targets to hit, in which combinations, for the illness takes many different forms and works through a stunning variety of biological mechanisms.
	New study unravels why common blood pressure medicine can fail Every year, more than 120 million prescriptions are written worldwide for thiazide drugs, a group of salt-lowering medicines used to treat high blood pressure.
