By studying thorium, silicon and iron concentrations in the Martian soil (based on the Gamma Ray Spectrometer data collected from onboard the Odyssey) David Baratoux, Michael Toplis and their colleagues have been able to deduce that Mars has cooled by about 80°C (176°F) over the past two or three billion years, which some have noted is slower than that for Earth.The researchers focused on twelve different volcanic plains on the Martian surface, each of a different age. Thorium, a radioactive element was chosen as one of the study agents due to the fact that when it’s heated it doesn’t get locked in with other elements, which makes it a good source of information for mantle temperatures when it is transported to the surface via volcanic activity (plus the fact that it continually emits gamma rays). Studying silicon in the volcanic soil, on the other hand, helps to gauge melting depth; and iron can be used to help figure out how accurate the first two are.The researchers were able to come to these conclusions because it is already well understood that the composition of magma pushed to the surface through melting of mantle rocks (creating volcanoes) is controlled by depth, temperature and pressure exerted before being forced to the surface. With data from the GRS they were able to measure the composition percentages of the studied elements and the degree of variation between them, and also to calculate the degree of melting; to which they were able to apply mathematical modeling that gave them the pace of cooling.In addition to coming up with a reasonable estimate of planet cooling, the team also came up with evidence to suggest that Mar’s lithosphere is thickening. By studying changing temperature patterns on Mars, and other planets, researchers hope to gain new insights into how our own planet might behave as the future unfolds. © 2010 ( — French researchers from the University of Toulouse have published a paper in Nature, that describes how they used data from NASA’s Mars Odyssey (currently orbiting the planet) to ascertain the amount of cooling that Mars has undergone over billions of years.

Exhumation of Shakespeare to determine cause of death and drug test

first_img Explore further © 2010 Thackeray is best known for his controversial suggestion nearly a decade ago which pointed to the possibility that Shakespeare had been a regular cannabis smoker. Utilizing forensic techniques, Thackeray examined 24 pipes which had been discovered in Shakespeare’s garden and determined that they had been used to smoke the drug.Citing that even after 400 years, Shakespeare is still one of the most famous people in history, Thackeray hopes to be able to end the question of how he died and establish a health history. With new state-of-the-art computer equipment he hopes to create a three dimensional reconstruction of Shakespeare. The hope is to be able to determine the kind of life he led, any diseases of medical conditions he may have suffered from and what ultimately caused his death.The new technology, nondestructive analysis, will not require the remains to be moved but will instead scan the bones. They are also hoping to collect DNA from Shakespeare and his wife and sister, all who are buried at Holy Trinity Church.Thackeray also hopes to find evidence to back his controversial claims years ago regarding Shakespeare’s marijuana smoking. Examining the teeth could provide the evidence they need. If they are able to discover grooves between the incisor and canine teeth, it could show them he was chewing on a pipe.This plan however goes against the final wishes of Shakespeare himself who had the following words engraved on his tomb: “Good frend for Jesus sake forebeare, To dig the dust encloased heare, Bleste be the man that spares thes stones, And curst be he that moves my bones.”The Church of England denies that any requests have been made to exhume Shakespeare’s body but Thackeray and his team hopes to gain approval in time to be able to make the determination before the 400th anniversary of his death in 2016.

(A) The behavioral setup is inside a bigger tank so that fish are acclimatized to the same water for 1 d before the experiment, housed in waiting containers in groups of 8–10 fish. At 1 h before the experiment, each fish is isolated and fed with frozen artemia in an individual container. The fish stays in the individual container until placed in the release chamber and gently pushed into the waiting chamber with a net that fits tightly between the walls to prevent the fish from going back to the release chamber. The door to the setup is then lifted and, once the fish enters the setup, it is closed. The camera records for 5 min from the opening of the door. After the experiment, the fish is pushed back to the release chamber, where it is caught. Then, a segment of wall opposite to the entrance door is removed, and water from outside is pumped into the central chamber so that odors are washed out.

This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of Surprisingly, this subtle change led to different mathematics that closely matched both the stickleback and zebrafish data. Confident in their new rule, the team tried using existing data in the Argentine ant obtained by Dr. Andrea Perna and his collaborators at Uppsala University in Sweden. "Beautiful, it worked again," says de Polavieja. "We'd found that a simple neural property could give us a rule for behavior in collectives that matched data very well for very different species." De Polavieja notes that their key innovation was theoretical. "Most previous rules were proposed as phenomenological rules to fit data," he explains. "Here we'd proposed to base these kinds of rules on Bayesian estimation, and had taken the right steps to obtain a rule that worked very well when compared to data."One of the study's key findings was that the different counting systems used by animals, including humans, can emerge from the common principle of using social information to make good decisions. "It turns out that both absolute and relative counting systems found experimentally are derived from our theory as particular cases," de Polavieja explains. "This came as a surprise, as it's not clear that social interactions are behind counting – but note that social interactions can be so important for survival that they might have a great impact on how animals count."The scientists are already charting their future research directions. "We're doing theoretical and experimental innovations," de Polavieja points out. "The main ones relate to more natural experiments in which animals move in space-time and not simply choose among a discrete set of options. We're extending the theory to cope with this general case and working on a tracking system to automatically follow each animal in a group." In addition, they're using their results to ask some basic questions, such as Why do animals aggregate? Which neural circuits most influence collective behavior? "We're moving in both directions."De Polavieja also sees their findings having a wider impact. "We're in the early stages of testing these results in human data," he concludes. "We're comparing our theoretical results with existing data on how humans get influenced by others – and since it's proving successful, we'll soon start our own experiments. I dream of being able to produce a theory that could help humans make group decisions." Journal information: Proceedings of the National Academy of Sciences Explore further (—Ethologists – those who study animal behavior under natural conditions – have long recognized that groups of various species, or animal collectives, use a variety of decision-making systems. For example, some species choose from among various behavioral options based on the number of animals that have already selected each alternative; other species follow Weber's Law, in which the relative number is the deciding factor; and for others, more complicated rules are involved. Recently, however, scientists at Instituto Cajal, Consejo Superior de Investigaciones Científicas, Spain, identified a single Bayesian-based decision-making rule underlying this observed diversity. Moreover, the researchers then experimentally demonstrated that this single rule quantitatively explains decision-making in zebrafish, and in existing datasets of argentine ants and sticklebacks. This suggests, they conclude, that decision-making based not just on individual behavioral, neurobiological, and psychological factors, but on social information, obtains across species – including humans. Dr. Gonzalo G. de Polavieja, Dr. Sara Arganda and doctoral student Alfonso Pérez-Escudero faced a variety of challenges in their study. "I started, together with Alfonso, to think about how to generate a theory of how individuals decide in groups," de Polavieja tells "It seemed to us that estimation of which of the available options to take using the behaviors of other animals was a good starting point. I knew from years of work in Neurobiology that all brains need to make estimations about the structure of the world from ambiguous sensory data. From this simple idea, we worked out the mathematics." The researchers used mathematics known as Bayesian estimation, but they generalized the equations to handle the case of an animal using other animals to improve estimations – and the mathematics they obtained were simple enough to make comparisons with data."We then used data on sticklebacks, from Dr. Ashley Ward and his collaborators at the University of Sidney in Australia, to compare our rule with data – and it worked very well," de Polavieja continues. "This gave us confidence to try our own experiments in zebrafish – but the theory failed this time. Then we made an apparently subtle change in our theory. Until this point we'd assumed that an animal was estimating which option was best to take, but then developed a very similar theory that estimated whether an option was a good one."last_img read more

Most experiments that claim to show the quantum Zeno paradox fall short

first_img Explore further Physicists present a non-destructive technique for measuring at the atomic scale ( —By their very nature, unstable particles will eventually decay, some faster than others. But according to the quantum Zeno paradox (QZP), an unstable particle that is observed continuously has been said to never decay. Though counterintuitive, this effect has been claimed to show up experimentally in numerous ways. Now in a new study, physicist Peter Toschek at the University of Hamburg in Hamburg, Germany, has argued that most of these experiments do not provide sufficient evidence of the QZP. By identifying the sufficient conditions necessary for proving the QZP, he confirms the validity of the paradox while probing deeper into its origins. © 2013 All rights reserved. Toschek’s paper, “The quantum Zeno paradox: A matter of information,” is published in a recent issue of EPL.”The QZP holds for all unstable quantum systems whose transition (or ‘decay’) is electromagnetically induced,” Toschek told .As he explained, most experiments that have claimed to prove the QZP (or its manifestation, the quantum Zeno effect) rely on measurements of “expectation values,” which are group averages that don’t provide information on individual objects, in particular on their survival times. Instead, he explains that the outcomes of quantum measurements should represent “eigenvalues,” which do provide information on individual quantum objects. He explains that the survival time of a particle can be derived from uninterrupted sequences of the detected eigenvalue of the initial, undecayed state of the quantum system (particle plus radiation field), provided an individual quantum object is addressed.For example, in some experiments that use light-irradiated atoms to demonstrate the QZP, a continuous measurement has been approximated by a series of short light pulses irradiating a group of 5,000 unstable atoms. Then the mean decay rate of the atoms has been measured. The results of these experiments show that the mean decay rate decreases when the pulse repetition rate increases, and this finding has been interpreted as evidence of the QZP.In these experiments, the measurement of the average decay rate of the entire group of atoms generates an expectation value, a classical quantity with a deterministic result—apart from small fluctuations from “projection noise.” In contrast, quantum measurements are known to show conditionally random results.In order to come up with eigenvalues instead of expectation values, Toschek explains that measurements of the decay process should be characterized by individual survival times. Importantly, this condition lies in the definition of the QZP. Further, the effects of each light pulse on the atom should be recorded. In this way, the information on the state of the atom gained by a measurement affects the prediction of the average of results. The results of classical measurements (like those measuring the mean decay rate) are insufficient to demonstrate the QZP because they are indistinguishable from results of other effects, such as spectral line-broadening by radiative saturation of an atomic resonance line.”So far, wide-spread misconception has claimed the QZP to be the cause of simple phenomena (for example, the ‘power broadening’ of irradiated atoms), which involve neither quantum measurements nor the Zeno effect (extension of the survival time under measurement),” Toschek said.While most of the claims for demonstration of the QZP have fallen short of satisfying both the criteria for being “quantum” and “Zeno,” a few experiments have met all the requirements and provide sufficient evidence to support the existence of the QZP. So the results of the current paper don’t question the validity of the paradox. Rather, they distinguish it from well-understood and unsurprising effects and present an explanation of the paradoxical aspects in terms of the transfer of quantum information.

Substrates change nanoparticle reactivity

first_img Citation: Substrates change nanoparticle reactivity (2015, June 30) retrieved 18 August 2019 from c(4 × 2)-2CO structures with TB and BB site occupations on a curved Pd(111) top facet. Credit: (c) 2015 PNAS, doi: 10.1073/pnas.1506939112 Chemical reactions on nanoparticles are dependent on properties that are not normally encountered on regular materials. One important property is the physical orientation of the nanoparticles with each other. In bulk reactions, bond distance and particle size are fixed features and the environment plays a more pivotal role. This is not the case in nanoscale materials where greater or smaller distances, orientation, and morphology between two particles can affect nanoparticle reactivity. One way to control nanoparticle orientation is to deposit metal nanoparticles on a substrate surface. It is only recently that scientists have begun to understand the role that substrate morphology plays in nanoparticle properties, including reactivity. In the case of Pd on a TiO2 substrate, Yim, et al. found that the strain within Pd nanoparticles changes when they are formed across the TiO2 substrate steps. This strain affects Pd reactivity.CO adsorbs onto the Pd nanoparticles with (111) top facet in three known adsorption sites at concentrations greater than 0.5 monolayers. As the concentration of CO increases, CO will fill bridge sites on palladium nanoparticles as well as hollow sites. It will then fill a combination of atop (directly on top of palladium nanoparticles) and hollow sites. However, where the Pd nanoparticle lattice curves, CO will bond in different sites.STM analysis shows that the Pd curvature is due to growth across the step on the TiO2 substrate. This leads to the Pd nanoparticles layering over the substrate steps in way reminiscent of laying a piece of carpet over a step. This leads to curved Pd nanoparticles described as having top (111) facets.To understand how the curved Pd morphology changes its reactivity, STM studies were performed after 0.5 monolayers of CO were adsorbed onto the Pd surface. Analyses showed that there were different regions of CO. One region has CO molecules occupying bridge sites as is expected when CO is adsorbed on to a Pd/TiO2 system. Another region, however, showed an atop-bridge configuration, which had not been reported for Pd(111) surfaces. Investigation of another step island showed that CO molecules occupy a combination of atop- and face- centered cubic hollow sites, another unobserved configuration for this system. Computational analyses showed that this difference in CO registry on the curved Pd nanoparticles is probably due to particle strain across the steps. Particle strain has been shown in other systems to affect adsorption of molecules on nanoparticles, although these systems do not show particle strain as localized as on the curved Pd nanoparticles across the TiO2 step islands shown in the work by Yim, et al. The Pd layer seems to elongate across the step edge and shrink in the direction perpendicular to the step edge, causing tensile strain and compression strain. This strain changes how CO interacts with Pd. CO typically binds to Pd at a 90-degree angle and has a double bond character. However, in these new orientations CO is 21.4-degrees from the normal of the Pd nanoparticle and displays a single bond character.This research has two important implications for nanoparticle-substrate interactions: First, it shows how substrate morphology plays a role in nanoparticle reactivity. Namely, “carpet growth” over step islands probably happens in other systems and may explain changes in reactivity. Second, changing the substrate morphology may be a way to tune nanoparticle reactivity. More information: “Influence of support morphology on the bonding of molecules to nanoparticles” PNAS, DOI: 10.1073/pnas.1506939112AbstractSupported metal nanoparticles form the basis of heterogeneous catalysts. Above a certain nanoparticle size, it is generally assumed that adsorbates bond in an identical fashion as on a semiinfinite crystal. This assumption has allowed the database on metal single crystals accumulated over the past 40 years to be used to model heterogeneous catalysts. Using a surface science approach to CO adsorption on supported Pd nanoparticles, we show that this assumption may be flawed. Near-edge X-ray absorption fine structure measurements, isolated to one nanoparticle, show that CO bonds upright on the nanoparticle top facets as expected from single-crystal data. However, the CO lateral registry differs from the single crystal. Our calculations indicate that this is caused by the strain on the nanoparticle, induced by carpet growth across the substrate step edges. This strain also weakens the CO–metal bond, which will reduce the energy barrier for catalytic reactions, including CO oxidation. Journal information: Proceedings of the National Academy of Sciences Parkinson’s disease appears associated with many cancers in Taiwancenter_img (—Nanoscale materials tend to behave differently than their bulk counterparts. While there are many theories as to why this happens, technological advances in scanning tunneling microscopy (STM) have allowed researchers to investigate many of these causes by looking at the properties of a single nanoparticle. One area that requires further investigation is how substrate topology affects nanoparticle reactivity. Using the well-known interaction between carbon monoxide (CO) and substrate-supported palladium (Pd) nanoparticles, researchers from the London Centre for Nanotechnology and University College London have demonstrated, for the first time, that the topology of the titanium dioxide (TiO2) substrate affects Pd nanoparticle reactivity.

Rubbery carbon aerogels greatly expand applications

first_img Researchers create shape-memory aerogels with rubber-like elasticity Explore further Citation: Rubbery carbon aerogels greatly expand applications (2018, March 19) retrieved 18 August 2019 from Journal information: Nature Communications The researchers, led by Chao Gao, Zhen Xu, and others at Zhejiang University, have published a paper on the highly stretchable carbon aerogels in a recent issue of Nature Communications.”We showed the possibility that neat inorganic materials can also possess rubbery elasticity,” coauthor Fan Guo at Zhejiang University told “The rubbery carbon aerogel opens a new material species that combines ultra-lightness, temperature-invariant high elasticity, and robust mechanical performance.”Due to the growing demand for stretchable electronics, researchers have recently been investigating methods to improve the elasticity of carbon aerogels, which typically are not very elastic. In the new work, the scientists designed carbon aerogels consisting of both graphene (a two-dimensional material) and multi-walled carbon nanotubes (CNTs, a one-dimensional material), assembled into four orders of hierarchical structures ranging from the nanometer to centimeter scale. To fabricate the material into aerogels, the researchers created an ink composed of graphene oxide and nanotubes, and then formed the aerogels via inkjet printing.In tests, the researchers demonstrated that the new aerogels exhibit a tensile strength that is 5 times higher than that of previous aerogels. They found that strong atomic bonding between the graphene and CNTs results in a synergistic effect, leading to greater stretching elasticity and stability. In addition, the new aerogels can withstand extreme temperatures, unlike most previous attempts at stretchable aerogels in which the aerogels become viscous or brittle when exposed to heat or cold.To demonstrate one possible application, the researchers attached three of the new stretchable aerogels onto the joints of a snake-like robot. The aerogels function as sensors to monitor the robot’s movements and configurations. Unlike conventional sensors that can detect only one-way deformation, the aerogel sensors can distinguish between multiple configurations, suggesting the possibility of a new generation of sensors with the ability for logic identification of sophisticated shape changes.Other potential applications of the stretchable aerogels include wearable electronic devices, aerospace applications, energy generation and storage, as well as using them as lightweight mechanical devices, especially in extreme temperature conditions.”This rubbery carbon aerogel opens many possibilities,” Guo said. “First, the strength and Young’s modulus [a measure of tensile elasticity] of carbon rubbers are lower than that of polymer elastomers. In general, the Young’s modulus of polymer rubbers are 1-2 orders of magnitude higher than our carbon rubbers. “Second, we are striving to make carbon aerogels more mechanically robust in order to bear extreme and complicated deformations, such as higher elongation and torsion. Meanwhile, more applications of this new carbon rubber can be explored and other types of inorganic rubbers can be achieved by means of this hierarchical synergistic assembly methodology.” More information: Fan Guo et al. “Highly stretchable carbon aerogels.” Nature Communications.

Published in Nature Communications Researchers have designed carbon aerogels that can be reversibly stretched to more than three times their original length, displaying elasticity similar to that of a rubber band. By adding reversible stretchability to aerogels’ existing properties (which already include an ultralow density, light weight, high porosity, and high conductivity), the results may lead to a host of new applications of carbon aerogels.

Mahabharata witnessed the Great War and destruction of life. It is not a tale of how a kingdom was won or lost  , it is a narrative of human tragedy. So is the Second World War, which witnessed a brutal destruction, death and the rise of Fascism. The recent conflicts in the Middle East and Palestine. Is not a full scale war as we understand now, but the brutality of the conflict has led to millions dead, homeless, and without any hope of a Nation/ State. Also Read – ‘Playing Jojo was emotionally exhausting’Many stories of Mahabharata were in ‘oral tradition’ in ancient India. It has at least 3 compositional layers. The first one is a Kshatriya tale with the name of ‘Jaya’, which is essentially a war-story. It is a poetic narrative of the battle of Kurukshetra.In the second layer, some tales based on the eternal notions of morality were incorporated into it. Human qualities like kindness, forgiveness, truthfulness and self-command were appended to the ‘Jaya’ to form the ‘Bharata’. And much later, in the beginning of the Gupta period, its final stratum was created. This is called the Brahmanical addition which primarily comprises elaborate eulogies of the deities and the Brahmins and is widely considered to be of poor literary value.
