Namely, the batteries, which measure 18mm in diameter and 65 mm in length, will offer a 4.0Ah capacity – that’s almost 30% higher than the largest capacity (3.1Ah) of today’s batteries of the same size. Panasonic plans to use the batteries primarily in notebook PCs, in which the Si-alloy anode makes it possible to cut the volume of a standard notebook PC battery pack by about half. Panasonic also hinted at using the batteries in vehicles in the future, although the battery’s weight will have to be reduced. Si-alloy’s attraction lies in its high theoretical capacity, which is at least 10 times greater than the capacity of graphite. However, one of the greatest challenges in developing Si-alloy-anode batteries is increasing their short charge/discharge cycle lifetime. During charge and discharge, the batteries have a large volumetric change of about 400%, which decreases their lifetime. With improved fabrication techniques and other modifications, Panasonic claims to have reduced the deterioration caused by the volumetric change. The company says that its Si-alloy-anode batteries can still maintain at least 80% capacity after 500 charge/discharge cycles. As the tech news site Nikkei notes, Panasonic’s commercial launch should further accelerate the Si-alloy development competition. Si-alloy anodes could accelerate the rate of increase of battery capacity. Capacity has been increasing at about 11% annually until now, but this new development represents an annual increase of 18%.

Many battery manufacturers are developing Si-alloy anodes, with Hitachi Maxell having previously announced plans to begin volume production by the end of fiscal 2009. Now, with its announcement of beginning volume production in 2012, Panasonic is the first company to reveal specifications of its Si-alloy anode product.
(Phys.org) —”If we want to exploit a rigorously hardened and tested type of computing system or networks of this type of computing system, we have to break new ground. Covert channels are communication channels utilizing means for communications that have not been designed for communication at all.” So begins a bracing paper published last month in the Journal of Communications. Titled “On Covert Acoustical Mesh Networks in Air,” the paper discusses devices that can support stealthy communication preventing immediate detection of the covert channels. The authors, Michael Hanspach and Michael Goetz, are research associates at the Fraunhofer Institute for Communication, Information Processing and Ergonomy (FKIE), in Wachtberg, Germany. Explore further More information: Research paper: On Covert Acoustical Mesh Networks in Air, www.jocm.us/index.php?a=show&catid=124&id=600 The authors warned that “Acoustical networking as a covert communication technology is a considerable threat to computer security and might even break the security goals of high assurance computing systems based on formally veriﬁed micro kernels that did not consider acoustical networking in their security concept.” Researchers in the past have described acoustic wave propagation used in underwater setups but the authors in their research did something different. “The underlying network stack is based on a communication system that was originally designed for robust underwater communication. We adapt the communication system to implement covert and stealthy communications by utilizing the near ultrasonic frequency range. We further demonstrate how the scenario of covert acoustical communication over the air medium can be extended to multi-hop communications and even to wireless mesh networks.”The authors showed that establishing covert acoustical mesh networks in air is feasible in setups with commonly available business laptops. (The authors noted that a covert acoustical mesh network can be conceived as a botnet or malnet that is accessible via nearfield audio communications.) For their experimental setup, they used five laptops as the mesh network participants. They installed Debian 7.1 on each laptop. Commenting on their work, Dan Goodin of Ars Technica said the new research shows that “high-frequency networking is easily within the grasp of today’s malware.” In an email, Hanspach said that commonly available laptops can communicate over their internal speakers and microphones, and form a covert acoustical mesh network. Over that network, “information can travel over multiple hops of infected nodes, connecting completely isolated computing systems and networks (e.g., the internet) to each other.”The authors, in their paper, also discussed countermeasures against covert acoustical mesh networks. These include the use of lowpass filtering in computing systems and a host-based intrusion detection system for analyzing audio input and output to detect irregularities.

© 2015 Phys.org Do micro-organisms explain features on comets? Kee noted that we are able in any realistic sense to detect only life forms that have a terrestrial-based biochemistry, so we would probably bet on bodies that have liquid water and some form of geological free energy source. He puts his hopes on space probes looking at out-of-equilibrium gas distributions in exo-planetary atmospheres. However, any potential findings revealed by these probes would be only an indication, without the capability to definitively determine the existence of alien lifeforms.We could also turn to meteorites in the ongoing search for E.T. and hope that these rocks came from a parent body that may have harbored life. If we’re lucky, relics of life are contained within that sample and have not been destroyed. Kee surprisingly admits that luck is really the key condition here.”As most of these relics are likely to have been fossilized in some way, we would need to cash in on some more luck so that we can demonstrate sufficient differences between such relics and potential abiotic mechanisms of formation on earth—chemical compositional differences, isotopic ratio’s mineral morphologies or, most valuable perhaps, presence of specific molecules which could only be produced by biogenic processes, etcetera,” he said.The biggest challenge is to clearly identify if the life forms existed on the studied meteorites a long time prior to re-entry into the Earth’s atmosphere. Before that is established, any new finding would be just a potential signature of extraterrestrial life. For example, in 2011, Richard B. Hoover, an astrobiologist of NASA’s Marshall Space Flight Center, claimed he had found the remains of living organisms from a parent celestial body in a rare class of meteorites, called CI1 carbonaceous chondrites.”The complex filaments found embedded in the CI1 carbonaceous meteorites represent the remains of indigenous microfossils of cyanobacteria,” Hoover claimed.His team used Environmental (ESEM) and Field Emission Scanning Electron Microscopy (FESEM) to analyze the meteorite samples, studying internal surfaces. For comparison, Hoover compared the samples to those of terrestrial minerals and biological materials.Hoover’s claims sparked controversy and NASA distanced from his conclusions, pointing out his lack of expert peer reviews. The findings were soon debunked after publication.More recently, two scientists suggested that the comet 67P/Churyumov-Gerasimenko, which is studied by the European Space Agency’s Rosetta spacecraft, hosts microbial alien life. The University of Buckingham’s Chandra Wickramasinghe and his colleague, Max Wallis of the University of Cardiff, insist that the characteristic features on the comet, including a black, carbon-containing crust and underlying ice; large, smooth ‘seas’; flat-bottomed craters and a surface peppered with mega-boulders, might only be explained by the presence of life.But the last week’s claims also sparked skepticism among other scientists specializing in the search for extraterrestrial life, debunking the newly presented hypothesis. The researchers rejecting the new findings emphasize that complex organics are generated in many places in the solar system through photochemistry and this is evidence for anything other than abiotic chemistry.So far, we haven’t found any convincing proof of alien life embedded in meteorites. However, Kee, undeterred by the long-lasting search and continuous skepticism, is looking to the future with hope.”In order to receive Willy Wonka’s Golden Ticket of Astrobiology, we would need to be ready to search as many meteorites as we can get hold of, which we already do. Overall, I reckon we would need to be lucky. But hey, many people have won the lottery. The trick is to keep buying the tickets,” Kee concluded. Explore further (Phys.org)—As we become more advanced in astronomy, continuously searching and finding lots of potentially habitable extrasolar planets that could harbor alien life, it seems that it’s not a matter of if but when we will find extraterrestrial organisms. However, the real tough problem here is: How we could determine if the alien life has really been found? “The question is not so much ‘when will we find extraterrestrial life?’ But ‘when will we know we have found extraterrestrial life?'” Terence Kee, the President of the Astrobiology Society of Britain told Phys.org. “My feeling is that we may indeed find signs of life in a few decades, but whether we will be unambiguously able to identify it as ‘extraterrestrial life’ – as opposed to terrestrial contamination or abiotic far-from-equilibrium processes – in such a short time-frame, I’m not so sure.” This is the “South Pillar” region of the star-forming region called the Carina Nebula. Like cracking open a watermelon and finding its seeds, the infrared telescope “busted open” this murky cloud to reveal star embryos tucked inside finger-like pillars of thick dust.

Citation: End-Permian mass extinction may have been driven by an ocean teeming with life (2015, August 7) retrieved 18 August 2019 from https://phys.org/news/2015-08-end-permian-mass-extinction-driven-ocean.html Scientists have speculated that during the Permian period, venting of oceanic hydrogen sulfide gas killed off most eukaryotes and allowed oceanic prokaryotes to flourish. An international collaborative of researchers has conducted an analysis of the chemistry embedded in oceanic geologic formations, providing new geochemical evidence for this theory. The study, published in the Proceedings of the National Academy of Sciences, links the end-Permian mass extinction event with climate change, geologic weathering, and widespread marine anoxia as a result of biogeochemical sulfur and carbon cycles.The reduction of sulfates in the ocean by microbes is an important pillar of the sulfur cycle. Most of the hydrogen sulfide in the ocean is reoxidized, with a fraction buried in sediment. Release from the sediment is another important factor, affecting sulfide formation and reactive iron availability. A notable increase in hydrogen sulfide would have affected the oceanic environment in a host of complex ways, creating major changes in biodiversity.The current study demonstrates successive enhanced organic matter degradation by microbial sulfate reduction. This produces hydrogen sulfide, which is toxic for most eukaryotes, killing them by interfering with mitochondrial energy production. Rather than a so-called “Strangelove” ocean in which all life dies off, the study proposes a huge reduction of species richness—a decline in marine biodiversity of around 80 percent. Carbonate-associated sulfate isotope data compiled by the researchers demonstrates that widespread euxenic zones resulted in sulfide toxicity, driving the marine biodiversity loss during this period. Under low competition pressure, prokaryotic life rapidly occupied the resulting vacant ecospaces. It’s a remarkable portrait of biological productivity that contradicts the idea of an entirely dead ocean. The researchers note that this scenario also reinforces the idea that life forms influence seawater chemistry. The authors write, “This study also emphasizes that, besides the property of organisms to construct a habitable planet, they can also act as a catalyst for destruction,” noting that marine life would have been quite different with the flourishing of prokaryotes.Geologic data from the Early Triassic that followed records increased sequestration of sulfur sourced from pyrite owing to the lack of eukaryotic organisms that would have irrigated oceanic sediments with O2 via burrowing. These and other processes generated a negative feedback loop of the carbon cycle in which enhanced production and sequestration of organic carbon was stimulated by global warming and rates of chemical weathering. “The prolonged disturbance after the end-Permian mass extinction contradicts a fast return (<100 ky) to predisturbance climate and carbon cycle," the authors note.The authors conclude that post-extinction marine prokaryote domination, particularly the sulfate-reducing microbes, might have exerted enormous influence on the carbon cycle in the Early Triassic, affecting marine conditions and global climate, preventing the planet's recovery for a long period of time.

The partitioning of sulfur among different exogenic reservoirs by biological and physical processes was of importance for this biodiversity crisis, but the exact role of bioessential sulfur in the mass extinction is still unclear. Here we show that globally increased production of organic matter affected the seawater sulfate sulfur and oxygen isotope signature that has been recorded in carbonate rock spanning the Permian−Triassic boundary. A bifurcating temporal trend is observed for the strata spanning the marine mass extinction with carbonate-associated sulfate sulfur and oxygen isotope excursions toward decreased and increased values, respectively. By coupling these results to a box model, we show that increased marine productivity and successive enhanced microbial sulfate reduction is the most likely scenario to explain these temporal trends. The new data demonstrate that worldwide expansion of euxinic and anoxic zones are symptoms of increased biological carbon recycling in the marine realm initiated by global warming. The spatial distribution of sulfidic water column conditions in shallow seafloor environments is dictated by the severity and geographic patterns of nutrient fluxes and serves as an adequate model to explain the scale of the marine biodiversity crisis. Our results provide evidence that the major biodiversity crises in Earth’s history do not necessarily implicate an ocean stripped of (most) life but rather the demise of certain eukaryotic organisms, leading to a decline in species richness. (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. Explore further
A disappearing feast: Mean flows remain slim after eating eddies Journal information: Nature (Phys.org)—A team of researchers at the University of Cambridge has succeeded in creating turbulence in a Bose–Einstein condensate (BEC) and in the process, have possibly opened the door to a new avenue of research. In their paper published in the journal Nature, the team describes how they achieved this feat and the evidence they found for a cascade. Brian Anderson with the University of Arizona offers a News & Views piece describing the work done by the team in the same journal issue and offers a brief overview of the characteristic distribution of kinetic energy in turbulent fluids. Explore further More information: Nir Navon et al. Emergence of a turbulent cascade in a quantum gas, Nature (2016). DOI: 10.1038/nature20114AbstractA central concept in the modern understanding of turbulence is the existence of cascades of excitations from large to small length scales, or vice versa. This concept was introduced in 1941 by Kolmogorov and Obukhov, and such cascades have since been observed in various systems, including interplanetary plasmas, supernovae, ocean waves and financial markets. Despite much progress, a quantitative understanding of turbulence remains a challenge, owing to the interplay between many length scales that makes theoretical simulations of realistic experimental conditions difficult. Here we observe the emergence of a turbulent cascade in a weakly interacting homogeneous Bose gas—a quantum fluid that can be theoretically described on all relevant length scales. We prepare a Bose–Einstein condensate in an optical box, drive it out of equilibrium with an oscillating force that pumps energy into the system at the largest length scale, study its nonlinear response to the periodic drive, and observe a gradual development of a cascade characterized by an isotropic power-law distribution in momentum space. We numerically model our experiments using the Gross–Pitaevskii equation and find excellent agreement with the measurements. Our experiments establish the uniform Bose gas as a promising new medium for investigating many aspects of turbulence, including the interplay between vortex and wave turbulence, and the relative importance of quantum and classical effects. Scientists have learned a lot about the nature of turbulence in fluids over the past several hundred years, some of which surrounds the way kinetic energy is distributed among components that have different momenta—which can be seen in action, as Anderson notes, by stirring cream into a cup of coffee. But until now, no one had succeeded in producing turbulence in a BEC, in which a gas of bosons is cooled to near absolute zero causing them to occupy the lowest possible quantum state, thereby allowing for viewing quantum phenomena—Anderson calls them “microscopic droplets of atomic gasses.”In this new effort, the researchers conducted experiments designed to discover what might happen if turbulence were introduced to a BEC, in this case, one made of rubidium atoms captured in a laser-created virtual box—this type of setup provided uniform density of the atoms. The team then applied a timed magnetic field that served to shake up the cloud of atoms, which added energy to the system. They then determined the momentum distribution. For small time intervals, they found most of the atoms in the cloud were in a low-momentum mode—more shaking pushed the atoms into a higher momentum mode. After approximately two seconds, the researchers found evidence of a cascade of excitations by releasing the cloud and capturing what occurred with a 2-D camera.The method used by the team to cause the turbulence in a BEC is likely to be used as a model for future experiments involving quantum turbulence.

© 2017 Phys.org One of the types of pollutants emitted by cars and trucks is nitrogen oxides (NOx), in particular NO2 and nitric oxide (NO). These pollutants have been in the news in Europe over the past couple of decades because many truck and car owners have chosen to switch to vehicles powered by diesel fuel, which costs less than gasoline—but such vehicles also emit more NOx. To combat air pollution, officials in Europe and the U.K have enacted emissions standards that have resulted in less NOx emitted into the atmosphere. But most such emissions have applied only to NO2, which has muddied the standards. Making things ever murkier—such standards have been based on the percentage of NO2 in total NOx emissions. This is because not only do vehicles emit NO2 directly, but NO turns into NO2 over time once released into the air. Now, it appears that the percentages that officials have been using to set their standards has been wrong.To get an accurate measurement of the true percentage of NO2 in the NOx being emitted by vehicles, the researchers analyzed data from roadside monitors across Europe. In looking at the data, they found that NO2 percentages had risen, as expected, during the period 1995 to 2010 (as people converted to diesel) but then as emissions regulations came into effect, the percentage of NO2 leveled off and has remained at those levels ever since. These levels, the researchers note, are roughly half of what is described by air quality policy, which suggests Europe may reach mandated levels sooner than thought. Gentner and Fulizi Xiong suggest the group’s finding could have also implications for developing nations as well because consumers there tend to buy used diesel vehicles from Europe. 5,000 ‘Dieselgate’ deaths in Europe per year: study Credit: CC0 Public Domain This document is subject to copyright.

(Phys.org)—A team of researchers at the University of York in the U.K. has found that the proportion of nitrogen dioxide (NO2) in nitrogen oxides in European traffic emissions is smaller than has been thought. In their paper published in the journal Nature Geoscience, the group describes analyzing data from roadside monitors over the course of many years and what they found by doing so. Drew Gentner and Fulizi Xiong with Yale University offer a News and Views perspective on the work done by the team in the same journal issue and suggest that the team’s findings could have implications for air pollution standards organizations in many more places than just Europe. Journal information: Nature Geoscience More information: Stuart K. Grange et al. Lower vehicular primary emissions of NO2 in Europe than assumed in policy projections, Nature Geoscience (2017). DOI: 10.1038/s41561-017-0009-0AbstractMany European countries do not meet legal air quality standards for ambient nitrogen dioxide (NO2) near roads; a problem that has been forecasted to persist to 2030. Although European air quality standards regulate NO2 concentrations, emissions standards for new vehicles instead set limits for NOx —the combination of nitric oxide (NO) and NO2. From around 1990 onwards, the total emissions of NOx declined significantly in Europe, but roadside concentrations of NO2—a regulated species—declined much less than expected. This discrepancy has been attributed largely to the increasing usage of diesel vehicles in Europe and more directly emitted tailpipe NO2. Here we apply a data-filtering technique to 130 million hourly measurements of NOx , NO2 and ozone (O3) from roadside monitoring stations across 61 urban areas in Europe over the period 1990–2015 to estimate the continent-wide trends of directly emitted NO2. We find that the ratio of NO2 to NOx emissions increased from 1995 to around 2010 but has since stabilized at a level that is substantially lower than is assumed in some key emissions inventories. The proportion of NO x now being emitted directly from road transport as NO2 is up to a factor of two smaller than the estimates used in policy projections. We therefore conclude that there may be a faster attainment of roadside NO2 air quality standards across Europe than is currently expected.

Citation: Warped diffusive radio halo detected around the galaxy NGC 4565 (2019, July 23) retrieved 18 August 2019 from https://phys.org/news/2019-07-warped-diffusive-radio-halo-galaxy.html Using the LOw-Frequency ARray (LOFAR), astronomers have discovered a diffuse radio halo around the spiral galaxy NGC 4565. The finding, reported in a paper published July 16 on the arXiv pre-print server, could shed more light on the nature of NGC 4565, disclosing important insights about star-forming activity and the distribution of cosmic-ray electrons in this galaxy. Radio haloes are commonly observed around late-type spiral galaxies seen in an edge-on orientation. Studies show that the emission in radio halos is dominated by the non-thermal radio continuum component, indicative of cosmic ray electrons (CRe) and magnetic fields.Very little is known about the transport of cosmic rays in galaxies other than Milky Way. Low-frequency radio continuum observations have the potential to change this. They allow to investigate the oldest CRe far away from star formation sites in the halos of galaxies.So a team of astronomers led by Volker Heesen of University of Hamburg in Germany used LOFAR to conduct deep, low-frequency (144 MHz) observations of NGC 4565. Located about 38.8 million light years away, the target is a late-type spiral galaxy at an almost edge-on orientation. It is a quiescent galaxy with a low star-formation rate and an average mass surface density.”We have observed the nearby edge-on spiral galaxy NGC 4565 with LOFAR at 144 MHz in the radio continuum to measure the distribution of CRe and magnetic fields,” the astronomers wrote in the paper.During the observations, the astronomers detected a warp in the radio continuum of NGC 4565 that is reminiscent of a neutral hydrogen line (HI) warp and identifying a slight flaring of the galaxy’s radio halo. The researchers assume that this flaring is caused by the warp as the vertical intensity profiles are asymmetric, which is in agreement with the warp. According to the study, a minimum age for the warp was estimated at approximately 130 million years. This is the spectral age of the galaxy’s CRe, during which they are transported into the warp.Taking into account the results, the astronomers concluded that the NGC 4565 may be in the aftermath of a period with more intense star formation. They added that the galaxy has a relatively old population of CRe that has slowly diffused away from the star-forming disc.”The weak outflow that may be seen at higher frequencies was therefore probably stronger in the past, which explains the diffusive low-frequency radio halo,” the scientists wrote.Emphasizing that NGC 4565 could be in transition from an outflow- to an inflow-dominated phase, the researchers noted that this could explain why it behaves differently to NGC 7462, the only other galaxy in which they have detected a diffuse radio halo. They added that their research proves the significance of LOFAR observations for improving the understanding of cosmic rays and galaxy evolution.
