The discovery of a more effective method to estimate polluting emissions from nitrogen fertilizers Explore further Professor Joseph Almog has developed a spray that can detect urea nitrate, a powerful explosive that can be created by non-professionals in relatively simple back-yard facilities. Urea nitrate is commonly used by Palestinian terrorists in Israel, as well as in suicide bombers’ belts and in the 1993 World Trade Center bombing in New York. Although urea nitrate is a colorless crystalline substance that is similar in appearance to sugar, Almog has developed a chemical color test, where a suspect´s hands are wiped with treated cotton, which will then turn bright red if the individual had recently touched urea nitrate. The test is based on the formation of a red dye in the chemical reaction between the chemical p-dimethylaminocinnamaldehyde and urea nitrate under neutral conditions.Almog and research student Nitay Lemberger, who are from Hebrew University´s Casali Institute of Applied Chemistry in Jerusalem, have added the bomb detector test to an arsenal of other forensics tests. Almog, a former Israeli Police Brigadier General and Director of the Identification and Forensic Science Division of the Israeli Police, has done previous research on color changing test fluids. His inventions include Ferrotrace, a chemical that turns dark violet when sprayed on hands that have recently held a pistol or grenade, an agent that reveals hidden fingerprints, as well as a kit that can identify a wide variety of explosives.While other methods exist to detect urea nitrate, the spray is much simpler and less expensive, and has the potential to be widely used. Another advantage is that the spray can detect minute traces of the explosive not only on hands, but also on door handles, luggage containers and vehicles. The chemical can also distinguish with a high level of accuracy between sugar or other similar white powders and urea nitrate.More information: Casali Institute of Applied Chemistry, Hebrew University Press Release Citation: Israeli Scientist Invents Bomb Detector Spray (2007, October 30) retrieved 18 August 2019 from https://phys.org/news/2007-10-israeli-scientist-detector.html A cotton swab, sprayed with a color-changing chemical, will turn red after contact with urea nitrate.

More information: Environmental science: The hidden costs of flexible fertility, Nature 485, 441 (24 May 2012) doi:10.1038/485441aUrgent public debate is needed over a European proposal to regulate environmental levels of the active ingredient in birth-control pills, say Richard Owen and Susan Jobling. Journal information: Nature Explore further Chinese team develop fuel cell that can clean water as it generates electricity One class of drug in particular has many environmentalists concerned; those that are found in birth control pills. One such ingredient in the “pill” is ethinyl estradiol, which is a type of estrogren. In people, it helps prevent pregnancy, in other organisms, however, it might cause problems with the development of sexual organs leading to infertility or birth defects. This is possible because when wastewater is treated before being dumped back into an ocean, lake or river, no attempt is made to remove this particular chemical. And that is why a college professor and a ecotoxicologist have teamed up to write a paper (published in the journal Nature) suggesting that a public discourse on the matter be held before public officials decide whether to dedicate funds to cleaning such drugs from wastewater, or not.Millions of women the world over take the pill every day; its development and use has given modern women the freedom to make choices their ancestors never dreamed of. But as with most advances in science, there is a price to pay and it can be found in the possibility of intersex fish and other amphibians that live in habitats close to where effluent from wastewater treatment facilities is pumped. The emphasis is on the possibility of it happening though, as thus far, it has not been proved that this occurs outside of testing labs.In their paper, Richard Owen and Susan Jobling argue that decision-making regarding expenditures to clean such chemicals from wastewater should follow a public discourse. This is in response to the announcement that the European Parliament legislative committee is set to decide whether to recommend to the full Parliament, allocating some €35 billion for cleaning the chemical from wastewater across Europe, in November. They don’t believe such an important issue should be addressed and decided in private, without input from non-invited scientists or those that will be footing the bill, i.e. regular people.They say whatever decision is made will likely set a precedent, which other countries are sure to follow, which makes it all the more important that as many voices as possible be heard. (Phys.org) — As people go about their daily lives, it’s easy to overlook the impact their lifestyle has on the environment. Resources are used and as a result of their use, certain elements are placed back into the environment, some of which many people may not even think about. One of these is what happens to chemicals we take in after our bodies finish with them? Some are breathed into the air though most are flushed down the toilet after being deposited into our feces and urine. Workers at waste treatment facilities could point out chemical ingredients found in shampoos, for example, or those used in the production of food for another and most particularly drugs that we take to keep our various ailments at bay. © 2012 Phys.Org Citation: Pair call for public discourse on treating wastewater contaminated with birth control pill chemicals (2012, May 24) retrieved 18 August 2019 from https://phys.org/news/2012-05-pair-discourse-wastewater-contaminated-birth.html This document is subject to copyright.

Play This high-speed video shows the robot jumping over thirty times its height in ~119ms. Credit: Wiley The trick, the researchers note, is to get the robot to jump in a way that is useful. In this case, it means in a way that keeps the robot reasonably level so that it can land on its feet. That requires fine tuning the amount of gas delivered to the tubes embedded in its legs. Explosions, they say, rather than blasts of air, or the releasing of springs, allows for a much more forceful jump. So well have their experiments gone so far that they say their little robots are now only constrained by the tubes that connect them. Important also is determining if the robot body can withstand the blast, and thus far, the team says, it’s come through with flying colors. © 2013 Phys.org This document is subject to copyright.

Instead of building stronger legs, or using compressed air, they are imbedding tubes in its legs that when filled with methane and oxygen and ignited, cause an explosion that propels the robot into the air. Using this technique, the researchers have managed to get a small rubbery, three legged robot to “jump” more than 30 times its own height. They report their results in a paper they’ve had published in Angewandte Chemie. In the quest to build robots with ever greater capabilities, researchers in the past couple of years have turned away from hard shelled programmable machines, to designs based on soft materials—they’re generally lighter and more amendable to changes in the environment. To that end, George Whitesides and colleagues at Harvard have been creating robots made out of rubbery silicone and then testing them to see what they can be made to do. In this latest test, the researchers built a three legged robot, that isn’t really able to do anything except jump. It’s connected via tubes to a base that delivers the gasses and of course the spark that sets it off. Explore further

No one of course has ever seen one, or been able to prove it exists. This is because, they say, of how weak it is compared to the other forces, such as electromagnetism—to be able to see it, some have suggested, would require a device so massive that it would collapse in on itself into a black hole. For this reason, some researchers have suggested that we will never be able to see it. In their paper, Krauss and WIlczek suggest that it might not be necessary to see it, because there might be a way to infer its existence by measuring the CMB.Their idea is that in the early universe, just after the Big Bang, as inflation was occurring—gravitational waves should have been created which in turn would have caused photons present in the CMB to scatter in a certain pattern. Finding that pattern, they continue, would mean finding evidence of a particle that was carrying the gravitational force—the graviton. And if evidence for the existence of a graviton could be found, then physicists would finally have their universal theory. They add that they believe that dimensional analysis could provide a link between those early gravitational waves and Planck’s constant, which is of course used in quantum mechanics.There are a couple of issues with the new theory—the first is that technology does not yet exist to measure the CMB in a way that would allow scientists to detect those early gravitational waves. Another is proving that any polarization found in the CMB can indeed be attributable to gravitational waves and not some other mechanism, force or process. More information: Using Cosmology to Establish the Quantization of Gravity, arXiv:1309.5343 [hep-th] arxiv.org/abs/1309.5343AbstractWhile many aspects of general relativity have been tested, and general principles of quantum dynamics demand its quantization, there is no direct evidence for that. It has been argued that development of detectors sensitive to individual gravitons is unlikely, and perhaps impossible. We argue here, however, that measurement of polarization of the Cosmic Microwave Background due to a long wavelength stochastic background of gravitational waves from Inflation in the Early Universe would firmly establish the quantization of gravity.

An analysis of community detection in networks shows that detection algorithms are better at identifying ill-defined communities than well-defined communities. This paradox suggests that algorithms may have greater success if they redefine their definition of a community. Credit: Radicchi, et al. ©2014 EPLA This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. While networks are used to represent a diverse range of interactions—from social to biological to physical—all networks share many of the same basic features. One common feature is their internal organization in communities. In intuitive terms, communities are well-connected subgroups (such as social cliques) within the larger network. In network terms, community structure is defined as a subgroup of nodes whose total number of internal links (links with each other) is larger than its total number of external links (links with nodes outside the subgroup). While identifying communities defined in this way may seem fairly straightforward, community detection is actually quite complicated in large, complex networks. Nevertheless, it is crucial for understanding the structural and dynamical properties of networks, and thus using networks to their full potential. For this reason, researchers have developed algorithms aimed at community detection. The problem is, when a community’s total number of internal links is only a little bit larger than its total number of external links, the algorithms may not detect the community. That is, the algorithms can only detect communities whose average value of the difference between the numbers of internal and external links surpasses a certain detectability threshold. The detectability threshold value changes in response to different network properties, although it is of course always greater than zero. Virtually all community detection algorithms face this limitation, making the limitation appear universal. In his new paper, Radicchi has discovered something that may call for a reconsideration of this seemingly universal limitation. His findings cut right to the heart of the definition of a community.The traditional definition of a community, as stated above, is based on averages. That is, if a community’s total number of internal links is larger than its total number of external links, the average node also has more internal than external links. However, any individual node could be very different than the average node. For example, some nodes may have more external links than internal links. Also, some nodes may have lots of links, both internal and external, while other nodes have very few links of either kind. Journal information: Europhysics Letters (EPL) More information: Filippo Radicchi. “A paradox in community detection.” EPL, 106 (2014) 38001. DOI: 10.1209/0295-5075/106/38001 Looking at nodes in this way is important because these properties affect the value of the detectability threshold—but not in the way that one would expect. As Radicchi explains, some communities are more high quality and better defined than others. High-quality, well-defined communities are those in which many individual nodes have more internal than external links. On the other hand, low-quality, ill-defined communities are those in which many nodes have more external than internal links, even though the community’s total number of internal links is still larger than the total number of external links (so it still falls under the definition of a “community”). It would seem that high-quality communities would be easier to detect than low-quality ones. But this is exactly the opposite of what Radicchi found. Instead, his main results counterintuitively show that the value of the detectability threshold is inversely proportional to the quality of the community. He thinks that the reason why high-quality communities are more difficult to detect for algorithms is that the algorithms are actually detecting subgroups that do not fully fit the intuitive definition of communities. This finding suggests that, if current algorithms could be modified to better detect the intuitive properties of communities, then they would likewise be better at detecting high-quality communities than low-quality communities. By the same token, these better algorithms might no longer be restricted by the “universal limitation” detectability threshold. As Radicchi explained, improving community detection algorithms could have wide-reaching implications for many different types of networks.”The detection of communities in graphs represents a way to ‘simplify’ the system under observation,” Radicchi told Phys.org. “Identifying the way in which nodes are organized in communities and how communities are organized in macro communities (i.e., hierarchical structure) is, in a certain sense, similar to drawing a map of the network. Depending on their level in the hierarchical structure, communities can play the same role as those played by cities, counties, states, countries and continents in the organization of locations in geographical maps. Concrete applications of community detection algorithms range from the design of efficient navigation protocols in the Internet to the creation of efficient systems of recommendation of commercial products to customers.” © 2014 Phys.org Harnessing the predictive power of virtual communities (Phys.org) —Sometimes paradoxes can be frustrating, but other times they can reveal something that was previously hidden.

More information: Locomotion control of hybrid cockroach robots, Journal of the Royal Society Interface, DOI: 10.1098/rsif.2014.1363AbstractSupernatural belief presents an explanatory challenge to evolutionary theorists—it is both costly and prevalent. One influential functional explanation claims that the imagined threat of supernatural punishment can suppress selfishness and enhance cooperation. Specifically, morally concerned supreme deities or ‘moralizing high gods’ have been argued to reduce free-riding in large social groups, enabling believers to build the kind of complex societies that define modern humanity. Previous cross-cultural studies claiming to support the MHG hypothesis rely on correlational analyses only and do not correct for the statistical non-independence of sampled cultures. Here we use a Bayesian phylogenetic approach with a sample of 96 Austronesian cultures to test the MHG hypothesis as well as an alternative supernatural punishment hypothesis that allows punishment by a broad range of moralizing agents. We find evidence that broad supernatural punishment drives political complexity, whereas MHGs follow political complexity. We suggest that the concept of MHGs diffused as part of a suite of traits arising from cultural exchange between complex societies. Our results show the power of phylogenetic methods to address long-standing debates about the origins and functions of religion in human society. (Phys.org)—A team of researchers at Texas A&M University has found a way to control the path a cockroach takes as it walks using wireless technology. In their paper published in Journal of the Royal Society Interface, the team, made up of mechanical engineers and entomologists, describe how they created little backpacks for the bugs and implanted electrodes to allow for movement control. Cockroaches are durable, of that there is little question, they live in places where others cannot. That makes them attractive research subjects. In this effort, the researchers sought to duplicate or improve on efforts by other teams attempting to remotely control insects or even rats or mice. In this case, the team created a small backpack and filled it with a very tiny microcontroller, wireless receiver and of course a battery. Next, they inserted electrodes into the body of a test cockroach to stimulate the bug’s nervous system. After putting the backpack on the cockroach and connecting the electrodes, the team found that they could control the movement of the bug by introducing stimulation to either its right or left side, similar to reins on a horse. That allowed them to direct the cockroach as it moved around in test areas. The approach, was not perfect, of course, the team found that the cockroach responded correctly approximately 60 percent of the time—but that could be enough, because if the bug does not respond correctly the first time, it can be given another jolt to correct its path.Such studies straddle ethical boundaries, some have noted, if humans create cyborgs to crawl into misbehaving nuclear reactors or skittle around in debris looking for survivors after earthquakes, for them, does that cross a moral line? What if the technology moves to dogs, cats or even monkeys?There is also the question of how well the technology might work in practice, prior research has found that sometimes the creature under study grows used to the electrode stimulation and begins to ignore it. The team in Texas appears unfazed, they next plan to see if they can achieve the same results with electrodes placed outside the body, avoiding the need for implants.

Researchers prefer citing researchers of good reputation Journal information: Proceedings of the National Academy of Sciences Most people probably realize that collaborations generally result in better work, both in and out of the sciences, due to the beneficial results of more minds working simultaneously on one or more problems, but do things work out better when two people work on multiple projects over many years, versus individuals building a career with serial pairings with different partners? That is what Petersen sought to learn.To find out, he studied publications by 473 physicists and biologists over the course of their careers, which covered 94,000 papers and involved 166,000 collaborators. In so doing, he discovered that between 60 and 80 percent of any given researchers’ collaborations lasted just one year or even less. He also identified what he terms super-ties, where pairs of collaborators worked together for decades—sometimes working together on roughly half of their projects. When comparing researchers that were part of super-ties against those that engaged in serial pairings, he found long-term pairings increased publication numbers for an individual researcher by, on average, 17 percent. Thus he concludes that long-term pairings on collaborative efforts are likely to increase a researcher’s publication productivity and in so doing boost his or her career development and success. Petersen’s paper also highlights what some consider a problem in scientific publications—people doing just enough work on an effort to get their name on a paper, bolstering their resumes by appearing as a researcher/author on multiple papers and thus engaging in multiple collaborations—in effect, gaming the system. Also, Petersen’s efforts focused on collaborative pairs—what is still not clear is whether researchers who are part of larger groups who collaborate together for many years gain the same sort of productivity boost. More information: Quantifying the impact of weak, strong, and super ties in scientific careers, Alexander Michael Petersen, PNAS, DOI: 10.1073/pnas.1501444112 AbstractScientists are frequently faced with the important decision to start or terminate a creative partnership. This process can be influenced by strategic motivations, as early career researchers are pursuers, whereas senior researchers are typically attractors, of new collaborative opportunities. Focusing on the longitudinal aspects of scientific collaboration, we analyzed 473 collaboration profiles using an egocentric perspective that accounts for researcher-specific characteristics and provides insight into a range of topics, from career achievement and sustainability to team dynamics and efficiency. From more than 166,000 collaboration records, we quantify the frequency distributions of collaboration duration and tie strength, showing that collaboration networks are dominated by weak ties characterized by high turnover rates. We use analytic extreme value thresholds to identify a new class of indispensable super ties, the strongest of which commonly exhibit >50% publication overlap with the central scientist. The prevalence of super ties suggests that they arise from career strategies based upon cost, risk, and reward sharing and complementary skill matching. We then use a combination of descriptive and panel regression methods to compare the subset of publications coauthored with a super tie to the subset without one, controlling for pertinent features such as career age, prestige, team size, and prior group experience. We find that super ties contribute to above-average productivity and a 17% citation increase per publication, thus identifying these partnerships—the analog of life partners—as a major factor in science career development. © 2015 Phys.org (Phys.org)—Alexander Michael Petersen, a researcher with the Lucca Institute for Advanced Studies in Italy has conducted a study looking into one measure of scientific career success—publication—and found that those people that pair with another researcher to form a long term collaboration, tend to have more productive careers.
