Nanotechnology news

Scientists create 'nano-reactor' for the production of hydrogen biofuel

Scientists at Indiana University have created a highly efficient biomaterial that catalyzes the formation of hydrogen—one half of the "holy grail" of splitting H2O to make hydrogen and oxygen for fueling cheap and efficient cars that run on water.

Ternary-layered separator to retard the shuttle of polysulfides towards highly-stable lithium–sulfur batteries

High-energy-density batteries are essential to meet the demand for future applications in portable electronics and electrical vehicles. Owing to the theoretical energy density of 2600 Wh/kg, the lithium-sulfur battery is considered one promising candidate for next-generation, high-energy battery solutions. However, shortcomings in fast capacity degradation and low cycling efficiency haven't been solved, which hinders the practical application of lithium sulfur battery system. A researcher at Tsinghua University has proposed a ternary-layered separator system for lithium-sulfur batteries with long lifespan, high coulombic efficiency, and high sulfur utilization.

Physics news

Coulomb blockade in organic conductors found, a world first

Generally, organic conductors has disorder structures so charge transfers from one place with high conductivity to another place with high conductivity. In such occasions, Coulomb blockade of charge transport takes place. It was thought that Coulomb blockade took place in low dimensional aggregates of inorganic particulates only at very low temperatures.

Cold fermions keep distance from each other

Today, quantum optical experiments provide methods to prove the rules that have been thought of and pressed into elegant mathematical equations in those days. In this regard, scientists in the Quantum Many-Body Division of Professor Immanuel Bloch at the Max Planck Institute of Quantum Optics have made a big step forward.

Beam-beam compensation scheme doubles proton-proton collision rates at RHIC

Accelerator physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have successfully implemented an innovative scheme for increasing proton collision rates at the Relativistic Heavy Ion Collider (RHIC). More proton collisions at this DOE Office of Science User Facility produce more data for scientists to sift through to answer important nuclear physics questions, including the search for the source of proton spin.

Ames Laboratory scientist's calculation featured on cover of PRL

Research performed by U.S. Department of Energy's Ames Laboratory Associate Scientist Durga Paudyal was recently featured on the cover of the November 13, 2015, issue of Physical Review Letters.

Earth news

Melting of massive ice 'lid' resulted in huge release of CO2 at the end of the ice age

A new study reconstructing conditions at the end of the last ice age suggests that as the Antarctic sea ice melted, massive amounts of carbon dioxide that had been trapped in the ocean were released into the atmosphere.

Large and increasing methane emissions from northern lakes

Methane is increasing in the atmosphere, but many sources are poorly understood. Lakes at high northern latitudes are such a source. However, this may change with a new study published in Nature Geoscience. By compiling previously reported measurements made at a total of 733 northern water bodies - from small ponds formed by beavers to large lakes formed by permafrost thaw or ice-sheets - researchers are able to more accurately estimate emissions over large scales.

Worldwide electricity production vulnerable to climate and water resource change

Climate change impacts and associated changes in water resources could lead to reductions in electricity production capacity for more than 60% of the power plants worldwide from 2040-2069, according to a new study published today in the journal Nature Climate Change. Yet adaptation measures focused on making power plants more efficient and flexible could mitigate much of the decline.

Meltwater from the Greenland ice sheet releasing faster

The firn layers of the Greenland ice sheet might store less meltwater than previously assumed. Researchers from the USA, Denmark and the University of Zurich fear that this could lead to increased release of the meltwater into the oceans.

Boosting farm yields to restore habitats could create greenhouse gas 'sink'

New research into the potential for sparing land from food production to balance greenhouse gas emissions has shown that emissions from the UK farming industry could be largely offset by 2050. This could be achieved if the UK increased agricultural yields and coupled this with expanding the areas of natural forests and wetlands to match its European neighbours.

Enough oxygen long before animals rose

Oxygen is crucial for the existence of animals on Earth. But, an increase in oxygen did not apparently lead to the rise of the first animals. New research shows that 1.4 billion years ago there was enough oxygen for animals - and yet over 800 million years went by before the first animals appeared on Earth.

Volcano in Nicaragua spews gas and lava

A volcano in Nicaragua that has been dormant for 110 years spewed gas and lava Sunday for the second time in a month.

Traces of islandic volcanoes in a northeastern German lake

Traces of volcanic ash originating from islandic volcanoes have been found in the sediments of Laker Tiefer See in the Nossentiner-Schwinzer Heide natural park in Mecklenburg-Vorpommern. This allows to more precisely date climate changes of the last 11500 years. An international team of geoscientists lead by the GFZ German Research Centre for Geosciences detected traces of in total eight volcanic eruptions on Island of which six could be precisely identified. The oldest eruption occurred 11400 years ago and the youngest from AD 1875 has been also described in historical documents.

Rare chance at never-before-studied Kimberley reef

The weather gods conspired to provide a rare chance to survey a remote and rarely visited section of north Kimberley reef recently, with footage that will inform the future study of reefs through climate change.

Manure applications elevate nitrogen accumulation and loss

Nitrogen (N) is an essential nutrient for plant growth, and nitrogen fertilization - including the application of manures - is a major management strategy in agriculture across the globe. However, the overuse and misuse of manures has resulted in the accumulation of surplus N in soil and its eventual migration to soil layers and groundwater. The authors of a new study found that the environmental risks of manure applications in high-input greenhouse environments may outweigh the benefits, and recommend that the role of manures be reexamined.

California braces for series of El Nino storms

After all the talk, El Niño storms have finally lined up over the Pacific and started soaking drought-parched California with rain expected to last for most of the next two weeks, forecasters said Monday.

Never rains but it pours for guano-hit Rome

Weekend rain washed away the dangerous pollution that has afflicted Rome in recent weeks but left city authorities with a new headache: roads and pavements made treacherous by bird droppings.

Tools for protecting drinking water

We place high demands on the quality of our drinking water. If pathogens or toxic substances found their way into the piping system, many people could become infected or injured very quickly. That's why this risk must be kept low. To do this, experts have developed technologies for a comprehensive monitoring, early warning and emergency management system.

NASA-NOAA's Suomi NPP satellite sees Ula moving away from Fiji

Tropical Cyclone Ula affected the Fiji group of islands over the weekend of January 2 and 3. Early on January 4, NASA-NOAA's Suomi NPP satellite showed the storm moved south as all Fiji warnings were dropped.

The Mississippi River floods more often than it used to, and at higher levels. Richard Knaup thinks he knows why.

Astronomy & Space news

Searching for water in the atmosphere of a Neptune-mass exoplanet HAT-P-26b

(Phys.org)—HAT-P-26b is an inflated, Neptune-mass exoplanet located about 437 light years from Earth, which orbits its parent star HAT-P-26 every 4.23 days. The planet has a relatively low surface gravity that is well suited for atmospheric characterization. However, we still know very little about the gas layer around this distant alien world. A team of astronomers led by Kevin B. Stevenson of the University of Chicago wants to change that, presenting new insights on the atmosphere of this celestial body.

Strong magnetic fields discovered in majority of stars

Strong magnetic fields discovered in majority of stars—Finding to impact understanding of stellar evolution

No fireworks in the galactic center

The center of our Milky Way galaxy, about twenty-five thousand light years from Earth, is invisible to us in optical light because of the extensive amounts of absorbing, intervening dust. Radiation at many other wavelengths, however, including the infrared, radio, and energetic X-rays, can penetrate the veiling material. At the heart of the galactic center is a supermassive black hole, SagA*, with about four million solar-masses of material. It is a relatively dim object, and shows some slight flickering that is thought to be the result of small blobs of material randomly accreting onto a disk around it. Its general passivity distinguishes SagA* from many other supermassive black holes in other galactic centers that actively accrete and heat large amounts of material, and then eject powerful bipolar jets of fast-moving charged particles.

Rotational clock for stars needs recalibration

New work from a team of astronomers led by Carnegie's Jennifer van Saders indicates that one recently developed method for determining a star's age needs to be recalibrated for stars that are older than our Sun. This is due to new information about the way older stars spin, as spin rate is one of the few windows into stellar ages. Their findings, published in Nature, have implications for our own Solar System, as they indicate that our own Sun might be on the cusp of a transition in its magnetic field.

Will 2016 be the year Elon Musk reveals his Mars colonial transporter plans?

Scientists teach bacterium a new trick for artificial photosynthesis

Trainers of dogs, horses, and other animal performers take note: a bacterium named Moorella thermoacetica has been induced to perform only a single trick, but it's a doozy. Berkeley Lab researchers are using M. thermoacetica to perform photosynthesis – despite being non-photosynthetic – and also to synthesize semiconductor nanoparticles in a hybrid artificial photosynthesis system for converting sunlight into valuable chemical products.

The origins of abiotic species

How can life originate from a lifeless chemical soup? This question has puzzled scientists since Darwin's 'Origin of species'. University of Groningen chemistry professor Sijbren Otto studies 'chemical evolution' to see if self-organization and autocatalysis will provide the answer. His research group previously developed self-replicating molecules—molecules that can make copies of themselves—and have now observed diversification in replicator mutants. They found that if you start with one ancestral set of replicator mutants, a second set will branch off spontaneously. This means that ecological diversity as encountered in biology may well have its roots at the molecular level. The results were published on Jan. 4, 2016, in Nature Chemistry.

New study models adhesion force as key to contact between two rough, yet elastic, surfaces

Imagine a new type of tyres whose structure has been designed to have greater adhesion on the road. Quite a timely discussion during the long winter nights. French physicists have now developed a model to study the importance of adhesion in establishing contact between two patterned, yet elastic, surfaces. Nature is full of examples of amazing adjustable adhesion power, like the feet of geckos, covered in multiple hairs of decreasing  size. Until now, most experimental and theoretical studies have only focused on the elastic deformation of surfaces, neglecting the adhesion forces between such surfaces. This new approach just published in EPJ E, by Laetitia Dies and colleagues from the Paris Sud University, France, matters when the scale of adhesive forces, is comparable to elastic forces on materials such a tyres. 

Biology news

Tiniest chameleons deliver most powerful tongue-lashings

Chameleons are known for sticking their tongues out at the world fast and far, but until a new study by Brown University biologist Christopher Anderson, the true extent of this awesome capability had been largely overlooked. That's because the smallest species hadn't been measured.

A worm with five faces

For eight years, a research team headed by Ralf Sommer and Matthias Herrmann travel to Réunion Island in the Indian Ocean. The scientists from the Max Planck Institute of Developmental Biology have now discovered a new nematode species on the island. The discovered nematodes live inside of fig plants and at first sight they look totally different. Much to their surprise, the scientists found that all the worms belong to a single species, which can develop five different mouth forms. The nematodes are genetically identical, however their food source decides on the mouth form. They are an extreme example of evolutionary divergence within a species.

An ancient symbiosis founded entirely on exploitation, not mutual benefit

Use of anticholinergic drugs does not increase risk for dementia in Parkinson's disease patients

Recent evidence has shown a greater risk of dementia, in particular Alzheimer's disease (AD), in individuals using anticholinergic medications regularly. These drugs are widely used by older adults to treat bladder dysfunction, mood, and pain, and many of them are available without prescription. Since these drugs are often used to treat both motor symptoms and non-motor symptoms in patients with Parkinson's Disease (PD), there is concern for increased risk of dementia. Contrary to expectations, a study in the current issue of the Journal of Parkinson's Disease determined that the cognitive performance of PD patients taking anticholinergic medications did not differ from those who did not.

New national perioperative guideline for the delivery of quality care for geriatric surgical patients released

CHICAGO: Responding to the needs of the country's growing older adult population, a new collaborative best practices guideline was released today for optimal care of older adults immediately before, during, and after surgical operations (a timeframe known as the "perioperative" period). The new consensus-based guideline was developed by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP®) and the American Geriatrics Society's (AGS) Geriatrics-for- Specialists Initiative (GSI), with support from The John A. Hartford Foundation. With more than 40 million older adults living in the U.S. today—and with that number expected to nearly double to 89 million by 2050*—providing expert guidance on surgical care is key since the need for surgical services increases with age and targeted guidance during the perioperative period can speed recovery.

Improving access to clinical trials when biopsies are required

The requirement for tumor tissue specimens and associated analyses in order to participate in clinical trials appears to be a significant barrier to clinical trial enrollment and may delay treatment. Potential solutions to reducing or eliminating these barriers include routine tissue banking at diagnosis, easing use of available diagnostic samples, development of less invasive tests, faster turnaround time at central laboratories or allowing for local testing and more resources for timely tissue collection.

Why too much evidence can be a bad thing

(Phys.org)—Under ancient Jewish law, if a suspect on trial was unanimously found guilty by all judges, then the suspect was acquitted. This reasoning sounds counterintuitive, but the legislators of the time had noticed that unanimous agreement often indicates the presence of systemic error in the judicial process, even if the exact nature of the error is yet to be discovered. They intuitively reasoned that when something seems too good to be true, most likely a mistake was made.

Students with influence over peers reduce school bullying by 30 percent

Curbing school bullying has been a focal point for educators, administrators, policymakers and parents, but the answer may not lie within rules set by adults, according to new research led by Princeton University.
