Citation: Radioactive isotope of tin confirmed to have doubly magic nucleus (2010, May 28) retrieved 18 August 2019 from https://phys.org/news/2010-05-radioactive-isotope-tin-doubly-magic.html Protons and neutrons in nuclei occupy orbital shells in a similar way to electrons in atoms. Nuclear magic numbers were first identified in 1948 by Maria Goeppert-Mayer, who shared in the 1963 Nobel prize for physics for her work on developing the nuclear shell model. Nuclear magic numbers are the numbers of nucleons (protons or neutrons) that form full (closed) outer shells in an atomic nucleus, like the magic numbers of electrons in helium, neon and other noble (super-stable) gases. The magic numbers for nuclei are 2, 8, 20, 28, 50, 82, and 126, while for electrons the magic numbers are 2, 8, 18, 32, and 50.Magic proton or neutron numbers give the nucleus greater stability and stronger binding, and are therefore usually more common than nuclei with unfilled orbital shells. In doubly magic nuclei both proton and neutron shells are filled, leading to even stronger binding and stability. The outer shells of doubly magic nuclei are rigidly spherical.Other confirmed doubly magic nuclei include helium-4, oxygen-16, lead-208, calcium-49, and nickel-48, which are abundant and stable, and nickel-56, which was discovered in 1998 and is less stable than the others, having a half-life of just 5.9 days. Tin-132 is even more unstable with a half-life of only four seconds, which has made confirmation of its doubly magic nature difficult. It has 50 protons and 82 neutrons, and is the first confirmed doubly magic isotope that is both neutron-rich and radioactive.Kate Jones, from the Department of Physics and Astronomy at the University of Tennessee in Knoxville, Tennessee, and her colleagues used a cyclotron reactor at the Oak Ridge National Laboratory dating from the 1950s to carry out the experiments. Jones said they were excited to have managed the feat, when most people thought it would not be possible until newer facilities were available.One method used to identify doubly magic nuclei has been to strip neutrons from the isotope and examine the properties of the stripped-off neutrons to infer the structure of the nucleus. To do this a film is made of the isotope in question, and this is then hit with a beam of deuterium (an isotope of hydrogen having one proton and one neutron).Tin-132’s extremely short half-life made this process impossible, so Jones and her team reversed it, using the isotope as the firing beam instead of as the film being hit. They accelerated a beam of tin-132 to about 10 percent of the speed of light and fired it at a target of deuterated polyethylene. As the tin-132 collides with the target some of the neutrons are stripped from the deuterium molecules to form tin-133, leaving the deuterium proton to fall back to the target. The researchers then analyzed the energy and angular distribution of the particles and were able to confirm the stripped neutron fell into a separate orbital shell above the closed inner shells of tin-132, which means the nucleus must be robustly spherical as expected for a doubly magical nucleus.The research findings will help physicists studying what is called the R-process, which is thought to be the process by which over half the elements heavier than iron are created through a series of neutron captures on seed nuclei such as nickel-56, probably in neutron star mergers or in collapsing supernovae.The research paper is published in the journal Nature.

Research team devises better method for mapping orbitals of molecules

first_img Molecular orbitals represent regions in a molecule where an electron is likely to be found; they are derived using mathematical formulas and are represented by cloudlike drawings with multiple nodes that are supposed to represent where electrons can go and are meant to demonstrate how molecules can share those electrons in chemical interactions or bonding. Since it was first invented in 1981, using the STM has generally been the best method available for creating images of individual atoms and their electronic properties. The STM is basically a piece of equipment with a metal appendage that has a tip width of just a few atoms. The tip is moved back and forth in the air very close to a sample being studied. Voltage is then applied allowing electrons to move between the tip and the sample. Doing so allows for measuring of the density of electrons on the surface of the material being studied which is then used to build the models.Unfortunately however, traditional STM has not been able to map orbitals of single molecules. This is because the density of electrons on the surface of an object, don’t give up the mathematical orbital nor does it have a fine enough resolution. Also there is the problem of having to place the sample on a metal surface which can hide what is going on with the molecules that comprise the sample. In the new approach the team solved the easiest part of the problem by coating the surface that the sample lays on with salt. Next, to improve resolution, they stuck a single carbon monoxide molecule on the end of the tip; this because carbon monoxide molecules have the property of having its outermost lobes paired close, with one positive the other negative phased. Such an arrangement makes the tip more sensitive to the sample material placed below it. Using this method the researchers were able to map the structure of the nodes of the molecular orbitals which allowed them to create images based on the places that held electrons. © 2011 PhysOrg.com More information: High-Resolution Molecular Orbital Imaging Using a p-Wave STM Tip, Phys.

The images of the frontier molecular orbitals show an increased lateral resolution compared with those of the bare tip and reflect the modulus squared of the lateral gradient of the wave functions. The contrast is explained by tunneling through the p-wave orbitals of the CO molecule. Comparison with calculations using a Tersoff-Hamann approach, including s- and p-wave tip states, demonstrates the significant contribution of p-wave tip states.via Physics Viewpoint Experiments Prove Existence of Atomic Chain Anchors This document is subject to copyright.

However, little is known about the ontogenetic origin of this capacity. Here we track the development of vocal combinatorial capacity in three species of vocal learners, combining an experimental approach in zebra finches (Taeniopygia guttata) with an analysis of natural development of vocal transitions in Bengalese finches (Lonchura striata domestica) and pre-lingual human infants. We find a common, stepwise pattern of acquiring vocal transitions across species. In our first study, juvenile zebra finches were trained to perform one song and then the training target was altered, prompting the birds to swap syllable order, or insert a new syllable into a string. All birds solved these permutation tasks in a series of steps, gradually approximating the target sequence by acquiring new pairwise syllable transitions, sometimes too slowly to accomplish the task fully. Similarly, in the more complex songs of Bengalese finches, branching points and bidirectional transitions in song syntax were acquired in a stepwise fashion, starting from a more restrictive set of vocal transitions. The babbling of pre-lingual human infants showed a similar pattern: instead of a single developmental shift from reduplicated to variegated babbling (that is, from repetitive to diverse sequences), we observed multiple shifts, where each new syllable type slowly acquired a diversity of pairwise transitions, asynchronously over development. Collectively, these results point to a common generative process that is conserved across species, suggesting that the long-noted gap between perceptual versus motor combinatorial capabilities in human infants1 may arise partly from the challenges in constructing new pairwise vocal transitions.center_img (Phys.org) —A team of researchers from Japan, Israel and the U.S. has found evidence that suggests birds and human infants learn to string syllables together in roughly the same way: through stepwise improvement. In their paper published in the journal Nature, the team describes how they taught songbirds to sing a new tune and compared an analysis of the results with sounds made by human infants saved in a database. Journal information: Nature The remarkable process that allows humans to learn to talk as they move through various stages of development has been the focus of a lot of research. To gain some insight into the process, researchers have often turned to the animal world—less complicated systems are easier to study. In this new effort, the researchers looked first at zebra finches. Prior research has led most in the field to believe that songbirds such as finches learn how to voice syllables by listening to the birds around them. After that, the ability to string them together into song is innate—it just happens. In this new research, the team has found evidence that it’s not innate, but is instead the result of a lot of work on the part of the bird.To come to this conclusion the team removed three young finches from others of their kind and taught them to sing in the lab. As expected, the birds picked up syllables rather quickly, mimicking the sounds they were played. Next, they were taught to string two syllables together, such as sound A and sound B. Then, they added another syllable, but introduced it as a pair, BC. Then finally, they asked the birds to sing the whole song, ABC, ABC, etc. But that was only the beginning, next the researchers taught the birds to sing another song that was made up of the same sounds, but in a different order: ACB. In studying how the birds went about learning the new song, the researchers discovered that they did so in stepwise fashion, trying out different parts before putting the whole song together. That proved, the researchers claim, that learning songs in songbirds, is not innate.

Credit: Ofer Tchernichovski and CHILDES database But that wasn’t the end of the study, the researchers found another team in Japan had been conducting a very similar study with Bengalese finches and came up with nearly identical results. Intrigued, they began looking at sounds made by babies that have been stored in a research database. After much analysis, they discovered that the infants were following a nearly identical path in learning to string syllables together to make words as the birds had done to make songs.The results of this research suggest that the basic underpinnings that lead to language development in people, is similar to song development in birds.last_img read more

Models show injecting aerosols into the atmosphere to prevent hurricanes possibly feasible

first_img(Phys.org)—An international team of Earth scientists has used eight Earth system model simulations of climate under the Geoengineering Model Intercomparison Project to predict the change in the number of hurricanes and other types of tropical storms that would occur over the next fifty years if sulfate aerosols were injected into the atmosphere to mitigate the impact of global warming. In their paper published in Proceedings of the National Academy of Sciences, the researchers describe the models and what they showed and suggest that such injections if done on a massive scale, might prove moderately effective—though they note that a different type of aerosol would have to be used to prevent harm to the ozone layer. As the planet keeps warming and efforts to reduce greenhouse gas emissions enough to make a difference fail, scientist have begun turning to other ways to mitigate problems in the future related to warmer temperatures and higher ocean levels, such as an increase in the number and intensity of hurricanes. One such technique that has been discussed in public forums, is injecting aerosols into the atmosphere in areas where tropical storms form—the shadowing effect would cool the air above the ocean preventing such storms from forming. In this new effort, the researchers used standard oceanographic models to attempt to learn whether such a technique might be viable.After inputting data meant to model an injection of sulfate aerosols over the next 50 years, in two different ways, the researchers found that the idea would likely work, but not as well as might be expected. The first modeled the impact of a volcano eruption-sized amount of aerosol injection while the second sought to mimic an increase in injection amounts to match the projected increase of greenhouse gas emissions. Because the second approach appeared to be the more likely outcome in real life, the researchers used that model to make their predictions. They found that if approximately 10 billion tons of such aerosols were pumped into the atmosphere annually, the result would be a halving of Katrina-sized hurricanes over the next half century. They equate it to mimicking a Pinatubo-sized eruption every two years—something they describe as very expensive, but doable.Of course, they note, there is no chance that such injections will begin anytime soon, because injecting that much sulfate aerosols into the atmosphere would destroy the ozone layer. But, their findings do suggest that if another, safer aerosol could be found, such a technique might prove viable. © 2015 Phys.org Hurricane Isabel (2003) as seen from orbit during Expedition 7 of the International Space Station.

Moore et al. Atlantic hurricane surge response to geoengineering, Proceedings of the National Academy of Sciences (2015). DOI: 10.1073/pnas.1510530112AbstractDevastating floods due to Atlantic hurricanes are relatively rare events. However, the frequency of the most intense storms is likely to increase with rises in sea surface temperatures. Geoengineering by stratospheric sulfate aerosol injection cools the tropics relative to the polar regions, including the hurricane Main Development Region in the Atlantic, suggesting that geoengineering may mitigate hurricanes. We examine this hypothesis using eight earth system model simulations of climate under the Geoengineering Model Intercomparison Project (GeoMIP) G3 and G4 schemes that use stratospheric aerosols to reduce the radiative forcing under the Representative Concentration Pathway (RCP) 4.5 scenario. Global mean temperature increases are greatly ameliorated by geoengineering, and tropical temperature increases are at most half of those temperature increases in the RCP4.5. However, sulfate injection would have to double (to nearly 10 teragrams of SO2 per year) between 2020 and 2070 to balance the RCP4.5, approximately the equivalent of a 1991 Pinatubo eruption every 2 y, with consequent implications for stratospheric ozone. We project changes in storm frequencies using a temperature-dependent generalized extreme value statistical model calibrated by historical storm surges and observed temperatures since 1923. The number of storm surge events as big as the one caused by the 2005 Katrina hurricane are reduced by about 50% compared with no geoengineering, but this reduction is only marginally statistically significant. Nevertheless, when sea level rise differences in 2070 between the RCP4.5 and geoengineering are factored into coastal flood risk, we find that expected flood levels are reduced by about 40 cm for 5-y events and about halved for 50-y surges.

New type of kill switch to prevent genetically modified microbes from wreaking

first_img 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. Science Fiction writers dreamed up the idea of mad scientists creating microorganisms that somehow get out into the world and kill everyone long before modern scientists had the skill to actually do it—but now that technology does exist and along with it fear that in trying to do something good, such as creating a cure for a bacterial disease, researchers could create a monster virus that not only harms patients, but jumps to others and causes serious harm or death. That fear is not ungrounded, as most biological researchers will attest, and that is why some of them are working on making genetically modified organisms safe. The idea is to modify genes to cause the organism to note when some chemical is present, and if so, to self-destruct—a modified virus or bacteria, for example, would die if exposed to a chemical present in the atmosphere. While such an approach is deemed practical by many, others would like to have access to a means for using the same technique on different organisms—those who hold patents on GMOs, for example, would like to be able to kill off their product if it gets into the hands of another entity. To meet that need, the researchers with this new effort came up with two new types of kill switches, which they have named ‘Deadman’ and ‘Passcode.’The Deadman solution is a new take on the kill switch idea from old time trains, a certain chemical must always be present or the modified microbe will die. Passcode, on the other hand is more complex, it combines the idea of a needed chemical and the absence of another. Microbes could be modified to be able to live only in the presence of two different molecules, for example, and the absence of another, or the reverse could be true. The designer could choose whichever “passcode” they desire.The main hurdle facing these new ideas and any others that may come along, of course, is in being able to prove that the microbes they modify will not evolve in ways that overcome the kill switches, either alone or by interacting with native microbes, making such efforts moot and possibly putting everyone at risk.

Researchers study interstellar medium in the galaxy NGC 3665

first_imgUsing ESA’s Herschel telescope a team of Chinese researchers has performed analysis of the interstellar medium in the early-type galaxy NGC 3665. The study offers insights into physical properties of the matter between its star systems. The results were presented January 16 in a paper published on arXiv.org. 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. Discovered by William Herschel in 1789, NGC 3665 is a lenticular early-type galaxy located some 108 million light years away. However, contrary to typical early-type galaxies, NGC 3665 is abundant in cool gas and has a low star formation rate surface density. Studying gas, dust and other matter in this galaxy, especially in its interstellar medium, could therefore explain the galaxy’s low star formation efficiency.A group of astronomers led by Meng-Yuan Xiao of the Nanjing University in China, has carried out an analysis of the physical properties of the interstellar medium in NGC 3665. For their research, they used far-infrared photometric and spectroscopic data obtained by ESA’s Herschel Space Observatory – an infrared telescope operating in space from 2009 to 2013. The dataset provided by Hershel was complemented by observations conducted with the Calar Alto Observatory (CAHA) in Spain.The observational campaign allowed the researchers to physically characterize NGC 3665’s interstellar medium by obtaining its fundamental parameters, which could improve our understanding of this atypical galaxy and star formation process taking place there.”In this paper, we focus on the photometric observations of NGC 3665 at 100, 160, 250, 350 and 500 µm, obtained with the Photodetector Array Camera and Spectrometer (PACS; – 4 – Poglitsch et al. 2010) and the Spectral and Photometric Imaging REceiver (SPIRE; Griffin et al. 2010) onboard Herschel, with five fine-structure lines of [N ii] 122 and 205 µm, [C ii] 158 µm, [O i] 63 µm, and [C i] 370 µm. We also perform optical spectroscopic observations of NGC 3665 with the CAHA 3.5m telescope,” the scientists wrote in the paper.According to the study, the researchers found that neutral and ionized gas in NGC 3665 have extended structures and follow the carbon monoxide line gas disk distribution, adding that the fluxes are stronger at the center.Furthermore, Xiao’s team estimates that the dust-to-stellar mass ratio of NGC 3665 is about 0.0011, which is nearly three times larger than the mean value of local lenticular galaxies. When it comes to the gas-to-dust mass ratio, this value is approximately 182, similar to that in our Milky Way galaxy. According to the authors of the paper, these findings, together with the calculated star formation rate of around 1.7 solar masses per year, suggest that NGC 3665 has large gas reservoirs and less star formation.Moreover, the researchers found that NGC 3665 has a weak active galactic nucleus in its central region, a very weak ultraviolet radiation field and has the lowest gas heating efficiency in photodissociation regions among different kinds of galaxies. The astronomers conclude that the new findings, compared with results provided by previous studies, indicate that suppressed star formation in NGC 3665 is most possibly caused by its compact, massive bulge through stabilizing cool gas reservoirs. © 2018 Phys.org Citation: Researchers study interstellar medium in the galaxy NGC 3665 (2018, January 29) retrieved 18 August 2019 from https://phys.org/news/2018-01-interstellar-medium-galaxy-ngc.html More information: The Physical Characteristics of Interstellar Medium in NGC 3665 with Herschel Observations, arXiv:1801.05110 [astro-ph.GA] arxiv.org/abs/1801.05110AbstractWe present the analysis of the physical properties of the interstellar medium (ISM) in the nearby early-type galaxy NGC 3665, based on the far-infrared (FIR) photometric and spectroscopic data as observed by the Herschel Space Observatory. The fit to the spectral energy distribution reveals a high dust content in the galaxy, with the dust-to-stellar mass ratio of Mdust/M∗ ∼ 1.1 × 10−4 that is nearly three times larger than the mean value of local S0+S0a galaxies. For the ionized regions (H~textsc{ii} regions), the electron density (ne) is around 49.5 ± 11.9 cm−3 based on the [N~textsc{ii}],122,mum/[N~textsc{ii}],205,mum ratio. For the photodissociation regions, the heating efficiency is in the range of 1.26 × 10−3 and 1.37 × 10−3 based on the ([C~textsc{ii}]+[O~textsc{i}],63,mum)/LTIR, which is slightly lower than other local galaxies; the hydrogen nucleus density and the strength of FUV radiation field are n ∼ 104 cm−3 and G0 ∼ 10−0.25, respectively. The above results are consistent with the presence of weak AGN and a low level of star-forming activity in NGC 3665. Our results give strong support to the `morphological quenching’ scenario, where a compact, massive bulge can stabilize amount of cool gas against star formation.
