The robot’s grippers, which don’t ever actually touch the surface as the robot climbs, operate on Bernoulli’s principle of fluid dynamics. Da Vinci surgical robot makes a tiny paper airplane More information: IEEE Spectrum The robot was developed by researchers at the University of Canterbury in New Zealand, with the results published in a recent ICRA paper by Matthew Journee, et al. According to Bernoulli’s principle, when a fluid (such as air) moves faster, its pressure decreases. To generate extremely fast-moving air, the researchers designed round grippers with tiny 25-μm gaps around the rim, out of which high-speed air can be forced. This design can compress the airflow so much that the air reaches supersonic speeds of Mach 3. The fast-moving air creates a low-pressure vortex inside the grippers that’s strong enough to pull the robot toward nearby surfaces, such as walls and ceilings, without actually touching them. The robot can roll on its two wheels, but the grippers are separated from the surface by a small gap.

Non-contact Bernoulli grippers have previously been used to pick up lightweight objects, especially those that are sterile or fragile. But in order to use the principle to enable a robot to climb, the researchers had to make the grippers five times stronger than the conventional version. They achieved this increase in strength by the carefully designed gaps, without the need for additional air pressure.The non-contact grippers could have applications in industrial inspections, and should be available in the coming months.

Play Image rotation filmed for a light beam propagating through a 10cm length of ruby rod, spinning the rod first clockwise and then anti-clockwise (as viewed from the camera position). Video: Science, DOI: 10.1126/science.1203984 To test this theory, the team created a square beam of green light, which they then directed at a spinning cylinder made entirely of ruby. The light was sufficiently strong enough to shine all the way through the cylinder, creating a square image on the other side. To see if the image was being rotated as the cylinder spun, the exact location of the projected image was noted, then the cylinder was spun in the opposite direction, to see if it would then be in a different position; which of course, it was. With the cylinder spinning at 30 revolutions per second, they found that the projected image was rotated about a third of a degree. They also found that increasing the amount of light tended to increase the amount of rotation of the projected image, in some cases, by as much as ten degrees.The research team note in their paper that they believe one application of this phenomenon could be its use in image encoding, just as current methods now include an image’s intensity. Scientists drag light by slowing it to speed of sound (PhysOrg.com) — In what might at first seem obvious, but isn’t after further thinking, a group of physicists from the United States and Canada have demonstrated, for the first time, that images generated by light, can be rotated via a rotating medium. In a paper published in Science, physicists Sonja Franke-Arnold, Graham Gibson, Robert W. Boyd and Miles J. Padgett describe how they were able to replicate the effects of light shifting via a moving medium, in a spinning medium, opening the door to a possible new way of encoding transmitted images. Explore further Scientists have long known that when a light is shone through certain moving material, that the light itself can be shifted along with it, due to the photons being absorbed and then released by the atoms in the medium. The effect has been demonstrated over the years and can be seen in the simplest of venues, such as light shining through a waterfall. Until now however, no one has shown that a similar effect might apply to a rotating medium.The idea is that if a beam of light, projected in a certain shape, such as a square for example, were to be shone through a spinning medium, such as a round block of glass, the image would emerge on the other side, but not exactly opposite; it would be off, just a little bit, in the direction of the spin. The amount of shifting would of course depend on both the speed of revolution of the cylinder and on the medium used, as some, such as rubies are able to cause more of a drag, per se, on the light as it moves through, than others.center_img More information: Rotary Photon Drag Enhanced by a Slow-Light Medium, Science 1 July 2011: Vol. 333 no. 6038 pp. 65-67 DOI: 10.1126/science.1203984ABSTRACTTransmission through a spinning window slightly rotates the polarization of the light, typically by a microradian. It has been predicted that the same mechanism should also rotate an image. Because this rotary photon drag has a contribution that is inversely proportional to the group velocity, the image rotation is expected to increase in a slow-light medium. Using a ruby window under conditions for coherent population oscillations, we induced an effective group index of about 1 million. The resulting rotation angle was large enough to be observed by the eye. This result shows that rotary photon drag applies to images as well as polarization. The possibility of switching between different rotation states may offer new opportunities for controlled image coding.via PhysicsWorld Citation: Physicists demonstrate rotated light images (2011, July 6) retrieved 18 August 2019 from https://phys.org/news/2011-07-physicists-rotated-images.html © 2010 PhysOrg.com PausePlay% buffered00:0000:00UnmuteMuteDisable captionsEnable captionsSettingsCaptionsDisabledQuality0SpeedNormalCaptionsGo back to previous menuQualityGo back to previous menuSpeedGo back to previous menu0.5×0.75×Normal1.25×1.5×1.75×2×Exit fullscreenEnter fullscreenlast_img read more

Android apps are full of potential leaks finds study

first_imgCredit: Sascha Fahl, et al. (Phys.org)—Many Android apps are capable of falling victim to Man in the Middle (MITM) attacks. How many? Far too many. Thousands of apps in the Google Play mobile market present vulnerabilities because of the way that protocols are implemented—namely, the Secure Sockets Layer (SSL) and Transport Layer Security (TLS). That Android apps are open to malware by now is a yawn-evoking statement if there ever was one, but a new paper provides findings that are making this week’s headlines. Computer science researchers from Philipps University of Marburg and Leibniz University of Hannover in Germany showed that Android apps that are used by over 180 million people can expose banking, social networking and email information.

Android users get malware with their apps More information: Research paper: www2.dcsec.uni-hannover.de/fil … android/p50-fahl.pdfVia Arstechnica © 2012 Phys.org They identified 41 apps available on the Google Play mart that leak sensitive information in traveling between smartphones and servers. The researchers used a smartphone with Android 4.0 Ice Cream Sandwich in their investigations. They installed potentially vulnerable apps on the phone and set up a WiFi access point with a Man in the Middle (MITM) SSL proxy. They equipped the SSL proxy with a self-signed certificate or with one that was signed by a trusted CA, but for an unrelated host name. Of the 100 apps selected for manual audit, 41 apps proved to have exploitable vulnerabilities. They captured credentials for numerous major services. “Furthermore, Facebook, email and cloud storage credentials and messages were leaked, access to IP cameras was gained and control channels for apps and remote servers could be subverted.”Their paper, testily called “Why Eve and Mallory Love Android: An Analysis of Android SSL (In)Security,” discovered the apps that have SSL code that either accepts all certificates or all hostnames for a certificate and thus are potentially vulnerable to MITM attacks.What also troubled the authors was the inability of many people in their survey to even recognize security threats attached to applications. “The results of our online survey with 754 participants showed that there is some confusion among Android users as to which security indicators are indicative of a secure connection, and about half of the participants could not judge the security state of a browser session correctly,” they said.Regarding secure connections, the researchers found that 47.5% of non-IT experts believed to be using a secure connection while the survey was served over HTTP. In addition, 34.7% of participants with prior IT education thought that they were using a secure channel when they were not. Only 58.9% of experts and 44.3% of non-experts correctly identified that they were using a secure or insecure connection when prompted.In summing up, the authors pointed to a need for more education and easier tools that can enable the secure development of Android apps. They also called attention to the need for research to identify which countermeasures can ensure the right mix of usability, security benefits and economic incentives for large-scale deployment.Android by the numbers merits that kind of care. Android is the most used smartphone operating system in the world. Building on the contributions of the open-source Linux community and more than 300 hardware, software, and carrier partners, Android has become the fastest-growing mobile operating system. The numbers keep shifting, but Android’s market share currently stays over 50 percent. Android users download more than 1.5 billion apps and games from Google Play each month, and the number is growing.last_img read more

Managing complexity Novel protein folding tool vastly simplifies understanding how sequence encodes

first_img Citation: Managing complexity: Novel protein folding tool vastly simplifies understanding how sequence encodes structure (2016, November 29) retrieved 18 August 2019 from https://phys.org/news/2016-11-complexity-protein-tool-vastly-sequence.html (Phys.org)—Protein folding is the process by which a polypeptide (a linear organic polymer chain consisting of many amino acid residues, or monomers) transforms from a random coil into the 3D conformation in which it can perform its biological function. Since different proteins fold into a range of very different shapes, the Protein Data Bank (PDB) – a database archive comprising experimentally-determined three-dimensional structures of large biological molecules, including numerous protein conformations – can be disarmingly complex. This is problematic because that space is fundamental to understanding how sequence encodes structure. Recently, however, scientists at Dartmouth College deconstructed the universe of known protein structures into reusable building blocks that they term tertiary structural motifs, or TERMs. (Structural motifs are compact blocks of a 3D protein structure.) They found that 50% of PDB protein conformations were described – at sub-Angstrom resolution – by a surprisingly small group of roughly 600 TERMs. Moreover, TERMs allowed them to discern sequence–structure relationships. The researchers state that these results can be used for protein structure prediction, protein design and other applications. In addition, some 600 TERMs describe 50% of the known protein structural universe at sub-Angstrom resolution. “This refers to the level of degeneracy we discovered in the protein structure space.” That only ~600 TERMs are required to describe half of all residues and inter-residue contacts in known protein structures suggests that at the local structural level, there just are not that many structural patterns that naturally emerge. There are, of course, a large number of more rare geometries, and full coverage of the protein structural universe requires tens or even hundreds of thousands of TERMs – but nevertheless, the majority of protein structure does appear to be quite degenerate at the local level.”As to the specific implications of their study for protein structure prediction, protein design, and other applications, Grigoryan points out that the major implication for protein design and structure prediction is the novel means of mining for sequence-structure relationships. “Statistical potentials, derived from known protein structures, have been employed for decades in both of these applications. However, such potentials typically describe the statistics associated with isolated simplistic structural features, like dihedral angles, individual interatomic or interresidue distances, or burial environments. However, TERMs offer the potential to describe sequence statistics in the context of holistic structural environments, which would be much more useful for both design and prediction.” Specifically, he explains, in design, this would allow for a better understanding of what sequences would or would not form the target structure; for prediction, it would help drive structural sampling towards structures whose TERMs are most consistent with the modeled structure. “A potential limitation is the amount of available data, because not all TERMs have sufficient known instances to synthesize accurate sequence models,” he acknowledges. “However, the early results shown in our paper, as well as some unpublished results in our lab, point to the fact that TERM-based statistics are already providing non-trivial insights that in many cases, other methods are unable to easily capture – and this is only going to get better as the amount of structural data continues to accumulate.”When asked about the implications of their work for synthetic genomics and synthetic proteomics, Grigoryan said “It’s a good question. I can certainly see a future in which a truly robust method for computational protein design serves as a key element in synthetic genomics and proteomics applications. I’d say that in terms of our current design techniques, we’re not quite there today – but our goal with TERM-based and other developments – as well as the general goal of our field – is certainly to keep improving the robustness of our methods, so that one day, we can offer them as black-box solutions to folks in other disciplines, whether that be materials science, biomedicine, or synthetic biology.”Moving forward, Grigoryan says that the team is focused on extending the capabilities of their TERM-based techniques to both protein design and structure prediction. “We’re also very interested in introducing ensemble-based modeling approaches into protein design: Since protein structural states are really conformational ensembles, the language of statistical mechanics is most appropriate for describing their behavior. Therefore, we’re pursuing methods for introducing statistical mechanics-based calculations towards improving the accuracy and robustness of protein design methods.”In addition to protein design and structure prediction, Grigoryan sees their study as having strong implications for our fundamental understanding of protein structure in general. “I think the new look at the protein structural universe our study offers can help not only with modeling and designing proteins, but it can also help with teaching about protein structure. The ideas of modularity and representation of standard motifs,” he concludes, “have already made their way into my own teaching here at Dartmouth.” Fig. 1. Discovering TERMs that optimally describe the protein structural universe. (A) A candidate motif is defined around each residue in the database, structural matches (from within the database) to each motif are identified using MASTER (58), and these matches are used in defining the coverage of every motif.

(B) A diverse selection of high-priority TERMs that span from one- to five-segment motifs, shown in the first to fifth columns, respectively. Shown in each column are representatives from the three most common secondary-structure classes for the given number of segments (SI Appendix, SI Methods). In both A and B, each TERM is represented with ten randomly chosen matches along with its centroid. The text underneath each TERM is formatted as follows: r; n (s/c) where r is the rank of the TERM in the set cover (lower rank corresponds to higher priority), n is the number of unique matches, s is the total fraction of universe elements covered by the TERM, and c is the marginal fraction of the universe elements covered by the TERM (i.e., fractional coverage of those elements not already covered by preceding TERMs in the set cover). Mackenzie CO, Zhou J, Grigoryan G (2016} Tertiary alphabet for the observable protein structural universe. Proc Natl Acad Sci USA 113(47):E7438-E7447. Grigoryan adds that by using residues and contacts rather than an a priori structural alphabet, defining the motif candidates was much easier. “It seemed particularly natural to define one candidate motif for every residue in the structural database,” he notes, “such that the motif would capture the residue and all of its contacts – that is, the motif would describe that residue’s local structural environment.” More information: Tertiary alphabet for the observable protein structural universe, PNAS November 3, 2016, Published online before print, doi:10.1073/pnas.1607178113 Researchers find possible universal code of protein structure A key finding discussed in the paper was that universal TERMs provide an effective mapping between sequence and structure. “Because universal TERMs recur many times in unrelated proteins,” Grigoryan tells Phys.org, “compiling the list of occurrences of each TERM allows us to start gleaning sequence rules that may underlie each of these structural motifs. The question was whether these sequence rules reflected fundamental determinants of structure, or simply noise from a limited structural database potentially biased by arbitrary evolutionary choices or the selection of proteins whose structures have been solved.” The team resolved this through a series of experiments in which they demonstrated that a significant component of the sequence statistics emerging from TERM matches does likely emerge from fundamental sequence-structure relationships.In effect, the natural utilization of TERMs provides a means of uncovering sequence–structure relationships. “Let’s say a given TERM is consistent of a two-strand beta sheet interacting with an alpha helix at a particular characteristic crossing angle and distance,” Grigoryan illustrates. “If we happen to have, for example, 600 instances of this motif from unrelated proteins, we essentially have 600 different examples of nature having made this structure with different amino-acid sequences. We can then use these 600 sequences to begin to understand what sequence features may be required or preferred to form such a structure – and we can do this for any TERM with sufficiently high usage in nature.”It turns out that by using this approach systematically for all TERMs contained in a given protein backbone structure, sequence variability predicted from TERM data agrees closely with evolutionary variation. “We can deduce a statistical model of what sorts of sequences would be likely to fold to that structure,” he explains. “If we then ask this model to produce a whole bunch of such sequences, we find that the emergent sequence variability is often in close agreement to the evolutionary variability observe for the corresponding protein.” © 2016 Phys.org This document is subject to copyright.

Prof. Gevorg Grigoryan discussed the paper that he and his co-authors published in Proceedings of the National Academy of Science of the United States of America. One of the primary challenges in their study was decomposing the set of known protein structures into standard reusable tertiary structural motifs. “The main challenge here was probably knowing where to begin,” Grigoryan tells Phys.org. “Our overarching goal was to describe, in his words, an alphabet of protein structure.” However, he points out that – unlike with text – the researchers were not able to visually determine where one structural unit (metaphorically a letter) began and another ended. “The number of ways in which we can potentially partition protein structure is extremely large, and so the task of finding a good decomposition seemed overwhelming.”The scientists addressed this problem by not defining a priori what the letters of the structural alphabet should be, but rather defining the task that these letters should accomplish – that is, describing the set of all residues and residue pair contacts observed in known protein structures. Next, they selected the smallest set of reusable building blocks they’re named tertiary structural motifs, or TERMs, that would achieve this goal.Another hurdle in determining the set of universal TERMs that capture all structure in the PDB was the difficult task of sifting through 13 million candidate TERMs, and describing which residues and contacts in known protein structures they individually explained. “Our previously-developed, efficient structure search algorithm MASTER helped us resolve this – but the total amount of computational time involved was still quite large, so we had to make use of a computer cluster.” A computer cluster is a single logical unit comprising multiple networked-linked computers.

Delhi govt to ban tobacco chewing from Monday

first_img“We have decided to come up with a notification to ban chewable tobacco in all forms from Monday in Delhi. Under this, no one will be allowed to sell, purchase or store chewable tobacco,” Delhi Health Minister Satyendra Jain told reporters on Friday.He said enforcement teams of Delhi Police as well as the health department have been asked to conduct surprise inspections across the city to ensure that the ban is implemented. “The teams have been told to be active on this,” Jain said. However, no such ban will be enforced on cigarettes. Health Department officials said there was a Delhi government notification in September 2012 which was in pursuance of a series of directions from the Supreme Court to ban gutkha in the city.

So, the purpose of banning gutkha was not served. Therefore, the health department last year started with a new proposal to ban all raw chewable tobacco products in Delhi, a senior official said.According to officials, gutkha is also being supplied to retailers in Delhi from neighbouring states of Uttar Pradesh and Haryana. Stepping up its efforts towards tobacco control, the health department has also launched an innovative drive, creating a ‘Tobacco Aware Citizens’ Directory’ to spread an awareness about its harmful effects.Sources in the government said the ban on the sale, purchase and storage of chewable tobacco in all forms would be for the next one year and thereafter, the government will re-notify it. “Lieutenant-Governor Najeeb Jung has already given his nod and the government will issue the notification to ban chewable tobacco in all forms from Monday,” said a senior government official.last_img read more
