Scientists identify quantum differences between light and heavy water

first_imgScientists know that light water (H2O) and heavy water (D2O) have similar but not identical structures. Using quantum mechanics, researchers have recently identified several differences between the two water isotopes that previous research had not predicted. Alan Soper from the Rutherford Appleton Laboratory in Oxfordshire, UK, and Chris Benmore from Argonne National Laboratory in Argonne, Illinois, have published their results in a recent issue of Physical Review Letters.Chemically speaking, D2O is an isotope of normal H2O, with each of the deuterium atoms having one neutron while the normal hydrogen atoms have no neutrons. The extra neutrons make heavy water about 10% denser than H2O, which can be seen when heavy water ice cubes sink in a glass of normal water. Biologically, this difference means that large amounts of heavy water can have harmful effects on animals, although it would take about two weeks of consuming only D2O and no H2O to kill a human.In their study, Soper and Benmore investigated the differences between light and heavy water on the quantum level. They used a combination of techniques – x-ray diffraction, neutron diffraction, and computer simulation – to discover the underlying mechanisms for why heavy water is more structured than light water, as previous research has indicated.“The task of understanding the structure and properties of any material is immense, and, in the case of water, is doubly difficult because of (a) the very keen interest in its properties, which are actually rather amazing and complicated compared to many common liquids, and (b) the difficulty of getting really reliable data on its properties,” Soper told PhysOrg.com. “The significance of our results is that they will challenge the theoreticians to come up with better models for water, something that has often eluded them and which even today is a subject of much study and endeavor.”Soper explained that some of their results could be controversial, since they contrast with predictions. First, the scientists found that H2O has a longer intramolecular OH bond than D2O’s corresponding OD bond length. Specifically, the OH bond is longer by about 0.03 angstroms, or 3%. Second, the intermolecular hydrogen bond (which connects two separate molecules) is shorter in H2O than in D2O. Here, the difference is about 0.07 angstroms, or 4%. Neither of these differences in bond length had been predicted in previous studies. Mussels are inspiring new technology that could help purify water and clean up oil spills A molecule of water: the red atom is oxygen, and the gray atoms are either hydrogen (light water) or deuterium (heavy water). Physicists have investigated the underlying mechanisms for why heavy water is more structured than light water.

While previous research had predicted an overall broadening of the H2O structure compared to the D2O structure, Soper and Benmore have pinpointed three specific differences, some of which are in opposition to earlier predictions.For one thing, the intermolecular OH peak is more asymmetric in H2O than D2O. Also, the distance between the hydrogen atoms on neighboring molecules is about 2% larger for H2O than in D2O. Finally, the number of hydrogen bonds per water molecule is less in H2O than in D2O (3.62 vs. 3.76). Together, these structural differences give light water a broader structure, and heavy water a narrower, more tetrahedral shape.Soper said that some of these unexpected results (such as the large degree of asymmetry in the hydrogen bond in H2O compared to D2O and the OH/OD bond length difference) may be contested by computer simulators. He also explained that the hydrogen bond length is caused by small electron movements that impact the proton (in hydrogen) or deuteron positions. Since the proton has a smaller mass than the deuteron, it sits higher in the quantum potential well (that holds the hydrogen atom) compared with the deuteron’s lower position in its potential well. “If that potential well is now perturbed by an approaching water molecule forming a hydrogen bond, then because the proton is higher in the well, it is more likely to be influenced by the approaching water molecule, drawing it away from the parent oxygen, more so than the deuteron, which is deeper in the well, and therefore less sensitive to perturbations from neighboring water molecules,” Soper said. This effect may play a role in the difference between the OH and OD bond lengths.The researchers also explained that understanding the structures of light and heavy water might not have any immediate applications, but could help researchers in a variety of fields down the road.“There is no obvious immediate impact from understanding these structures, apart from the obvious point that it will no doubt spur theoreticians to greater efforts to see if they can understand our findings,” Soper said. “Water is arguably the most important material in the human environment. Though there are lots of other materials we can and do study, somehow water captures major interest because of its fundamental importance to us. “Ultimately, if we understand water better, we will become better at predicting its properties, such as its ability to form crystals and water droplets in the atmosphere which in turn can cause immensely damaging storms as a consequence, its ability to act as the medium in which life has evolved, as the medium in which proteins will fold to their native structures, as the material used by our industry to both heat and cool, as the material used as a solvent and as a cleaner. The list is rather endless!”More information: Soper, A.K. and Benmore, C.J. “Quantum Differences between Heavy and Light Water.” Physical Review Letters 101 065502 (2008).Copyright 2008 PhysOrg.com.

Can you talk Apple patent calls on iPhone status check system

first_img More information: Patentvia AppleInsider Credit: USPTO (Phys.org) —An Apple iPhone invention would allow you to check the availability status of another iPhone user before you make the phone call. The advantage for the caller would be avoiding being dumped into voice mail without knowing when it would be a good time to call. The invention is not something available to Apple users; it is only a patent filing, which was published Thursday by the US Patent and Trademark Office. The application was originally filed in February 2012. Inventors are named as Devrim Varoglu and Swapnil Dave. The patent title is “Methods to Determine Availability of User Based on Mobile Phone Status.” The status information might include more information than whether the person is free to take the call: Remaining battery life, time zone, current location, strength of the callee’s signal (if it is indicated that the remote mobile phone is in an area that does not have a good reception, the local user may decide not to call) and whether the callee is in some special mode—normal, vibrate, airplane. Explore further Anti-Spoofing Bill Would Protect Caller ID According to the patent, “if the remote mobile phone is operating in a vibration mode, a user of the local mobile phone may interpret that the user of the second mobile phone does not want to be called upon. In this example, the local user may defer calling or send an email or a text instead.”Apple’s patent would reduce uncertainty of how likely the callee would be able to return a call quickly, and the caller could decide, after viewing the status on screen, whether to complete the call or to use another communication mode such as email.On the callee’s side, the advantage might be a way to avoid rings that can interrupt an office meeting, or any other event.How it works: The iPhone owner sets preferences and user sharing policies on the iPhone, which then reports to the server at preset intervals. As such, the phone automatically reports the operating status and conditions to a server; the process is taking place in the background. On the caller’s side, the device would display the contact’s operating status data automatically. The patent makes note of why this would be advantageous as compared with conventional caller ID. “Caller ID service is conventionally available to provide a callee with limited information about a call for call screening purposes, with the callee usually having very few options to manage the call. In particular, for most callees, the only available actions are to accept the call or decline it by either not answering or allowing an answering machine or voice mail system to respond. The caller in such cases has no control over whether or not the call will be accepted.”More advanced Caller ID services can provide the callee with limited interaction with the caller to assist the call screening process, thereby giving both the caller and the callee more control over the call. However, despite the limited interaction, the caller still has no effective way of knowing when the callee is willing to accept their call.” © 2013 Phys.org Citation: Can you talk?

Marmosets found to learn to take turns when vocalizing

first_img © 2015 Phys.org More information: Vocal turn-taking in a non-human primate is learned during ontogeny, Published 22 April 2015. DOI: 10.1098/rspb.2015.0069 AbstractConversational turn-taking is an integral part of language development, as it reflects a confluence of social factors that mitigate communication. Humans coordinate the timing of speech based on the behaviour of another speaker, a behaviour that is learned during infancy. While adults in several primate species engage in vocal turn-taking, the degree to which similar learning processes underlie its development in these non-human species or are unique to language is not clear. We recorded the natural vocal interactions of common marmosets (Callithrix jacchus) occurring with both their sibling twins and parents over the first year of life and observed at least two parallels with language development. First, marmoset turn-taking is a learned vocal behaviour. Second, marmoset parents potentially played a direct role in guiding the development of turn-taking by providing feedback to their offspring when errors occurred during vocal interactions similarly to what has been observed in humans. Though species-differences are also evident, these findings suggest that similar learning mechanisms may be implemented in the ontogeny of vocal turn-taking across our Order, a finding that has important implications for our understanding of language evolution. Explore further Citation: Marmosets found to learn to take turns when vocalizing (2015, April 22) retrieved 18 August 2019 from https://phys.org/news/2015-04-marmosets-vocalizing.html In the primate world, only humans are able to listen to a sound made by someone else and mimic it, a skill that has led to communication and the different languages spoken around the world. Scientists know that part of communicating involves one person listening to what another says, before responding. This requires an ability to understand what it means to take turns when vocalizing. In this new study, the researchers have found that a young marmoset (a small silvery coated South American monkey) was also able to learn to take turns as part of vocalizing.In their study, the researchers studied the vocalizations of a pair of captive marmoset twins (and their parents) over the first year of their life and report that they observed two parallels to language development. The first was that taking turns when vocalizing was a learned behavior. The second was that the young marmosets were essentially taught to take turns vocalizing by their parents in ways that are similar to the methods human parents use to teach children to wait for another person to finish speaking before they try to speak themselves.In watching the monkeys as they grew, the researchers noted that if a youngster made a vocalization while a parent was vocalizing, that vocalization was typically ignored by the adult, which resulted over time in the youngster learning to wait for the adult to finish before vocalizing. They noted that as time passed, the young monkeys became less likely to interrupt—though it was more pronounced with their mother than with their father.The researchers suggest their findings indicate a learning mechanism that is similar across all primates which could lead to a better understanding of the development of language in humans. (Phys.org)—A trio of researchers with the University of California has found that marmosets learn to wait for others to stop making noise before they vocalize, at a very young age. In their paper published in Proceedings of the Royal Society B, Cecilia Chow, Jude Mitchell and Cory Miller describe a study they undertook with young marmoset twins and their parents and what they learned by doing so.center_img Journal information: Proceedings of the Royal Society Common marmoset.

Diamond inclusions suggest free flowing water at boundary between upper and lower

first_img Citation: Diamond inclusions suggest free flowing water at boundary between upper and lower mantle (2018, March 9) retrieved 18 August 2019 from https://phys.org/news/2018-03-diamond-inclusions-free-boundary-upper.html More information: O. Tschauner et al. Ice-VII inclusions in diamonds: Evidence for aqueous fluid in Earth’s deep mantle, Science (2018). DOI: 10.1126/science.aao3030AbstractWater-rich regions in Earth’s deeper mantle are suspected to play a key role in the global water budget and the mobility of heat-generating elements. We show that ice-VII occurs as inclusions in natural diamond and serves as an indicator for such water-rich regions. Ice-VII, the residue of aqueous fluid present during growth of diamond, crystallizes upon ascent of the host diamonds but remains at pressures as high as 24 gigapascals; it is now recognized as a mineral by the International Mineralogical Association. In particular, ice-VII in diamonds points toward fluid-rich locations in the upper transition zone and around the 660-kilometer boundary.Press release A team of researchers from the U.S., China and Canada has found evidence in diamonds of free-flowing water in the boundary between Earth’s upper and lower mantle. In their paper published in the journal Science, the group describes analyzing inclusions in diamonds spewed from volcanoes and what they found. 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. The researchers were looking for molecular forms of carbon dioxide as part of carbon cycling in the Earth’s mantle when they came across evidence of something else. They had collected diamonds spewed from volcanoes (or pushed to the surface by other geologic activity) in Zaire, China, Sierra Leone and other locations in southern Africa, and were studying them by bouncing X-rays off the diamonds’ inclusions, when they came across samples of ice VII—a form of ice that does not occur naturally at the surface. The find was significant, because ice VII forms at very high pressure—approximately the amount of pressure found at depths of 610 to 800 kilometers beneath the Earth’s surface. This, the team notes, suggests that water must have been freely flowing at such depths to form the inclusions they observed. Such depths, they further note, fall into the transition zone in the mantle, a part of the Earth’s interior that is still a source of mystery.Prior research has shown that the mantle is made up mostly of hot rock under a lot of pressure. It has a lower layer, closest to the core, a transition layer, and an upper layer that eventually meets the crust. Prior research has also shown that the upper mantle has some water, which hints that there may also be water in the transition layer. The diamonds the researchers were studying would have been encased in liquid somewhere in the transition zone. The high temperatures there would not have allowed them to crystallize, however—it was only as they moved to the surface that crystallization would have occurred. The high pressure would have been maintained inside the diamond, but the temperature would have dropped dramatically. The idea of water moving around in the transition layer is intriguing, the team reports, because it has implications for tectonic plate shifting. Using Argonne’s Advanced Photon Source, researchers identified a form of water known as Ice-VII, which was trapped within diamonds that crystallized deep in the Earth’s mantle.

Rath Yatra This year hot wheels to replace ageold chariot

first_imgDarjeeling: Even the Gods haven’t been able to resist the luxury of modern technology. Lord Jagannath, his brother Lord Balabhadra and sister Devi Subhadra are all set to trade their age-old chariot for fast wheels in Siliguri for this year’s Rath Yatra.On the occasion of the Chariot festival on Friday, the trio will be heading to their aunt’s house (Gundicha temple) in Innova cars.As custom has it, on the day of Rath Yatra, Lord Jagannath, accompanied by his siblings, comes out in wooden chariots and takes a ride to the aunt’s house, meeting devotees en route. After spending a week at his aunt’s house, they return back to the main temple. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killed”Earlier, we used to take Lord Jagannath, Lord Balabhadra and Devi Subhadra on a single chariot through the main thoroughfares of Siliguri. They used to then return to the temple premises and were kept on a specially-prepared platform for a week before returning to the main temple. This year, however, there is a change,” stated Nam Krishna Das, Communication Officer, ISKCON, Siliguri. This year, a spot has been earmarked in Shivmandir on the outskirts of Siliguri town opposite gate number 2 of the North Bengal University. A pandal has been erected where religious festivities will be held for a week. The Lord and his siblings will be putting up in the house of a devotee, adjacent to this spot, which will be treated as the Gundicha Temple. Also Read – Naihati: 10 councillors return to TMC from BJPThe police were reluctant to give permission for the slow-moving chariots to be pulled to Shivmandir through the congested roads. “We then decided to use Innovas to transport the Gods. This will help avoid the traffic jams,” added Das.However, devotees need not worry. The trio will first take a trip around Siliguri in the wooden chariot (like previous years), return to the temple and then ride three separate Innovas to the Gundicha temple.”Every year we have one single Rath (chariot.) However, we have decided to have three smaller sized hydraulic chariots from next year. Overhead wires are a big problem so we have designed hydraulic chariots that can negotiate through the overhead wires and cables,” added the communication officer. The old wooden chariot has got a fresh coat of paint. The Lords will traverse the ISKCON temple, Sevok Road, Hill Cart Road, Haiderpara route to return to the ISKCON temple in the wooden chariot. From the temple they will then proceed to their aunt’s house in Shivmandir in Innovas.”It is not possible to transfer the idols to the cars from the Rath in the middle of the road. Hence, after the chariot ride, they will first return to the temple,” explained Das.last_img read more

An emerging family of lightweight tablets can convert to a notebook-like device and back.Take the Transformer Prime by Asus, a tablet powered by Android’s Ice Cream Sandwich operating system that comes with a full full-size detachable keyboard dock. What you get is a full-featured tablet that’s thin and weighs a little less than a pound a half.While the detachable keyboard can be more useful for typing than a separate Bluetooth keyboard or typing directly on the tablet display, the real reason to consider the Transformer Prime is data connectivity. It comes with an HDMI port, Micro SD Card Reader and USB port. And the ability to plug into most external displays such as monitors and projectors can transform it into a mobile presentation tool.The Transformer Prime starts at about $500 for the 32GB version — comparable to other less business-friendly tablets such as the new iPad from Apple.Related: 6 Tips for Building Better iPad Presentations Listen Now 3.

Elon Musk and Mark Zuckerberg Are Arguing About AI But Theyre Both

first_img 5 min read In Silicon Valley this week, a debate about the potential dangers (or lack thereof) when it comes to artificial intelligence has flared up between two tech billionaires.Facebook CEO Mark Zuckerberg thinks that AI is going to “make our lives better in the future,” while SpaceX CEO Elon Musk believes that AI a “fundamental risk to the existence of human civilization.”Who’s right?Related: Elon Musk Says Mark Zuckerberg’s Understanding of AI Is ‘Limited’ After the Facebook CEO Called His Warnings ‘Irresponsible’They’re both right, but they’re also both missing the point. The dangerous aspect of AI will always come from people and their use of it, not from the technology itself. Similar to advances in nuclear fusion, almost any kind of technological developments can be weaponized and used to cause damage if in the wrong hands. The regulation of machine intelligence advancements will play a central role in whether Musk’s doomsday prediction becomes a reality.It would be wrong to say that Musk is hesitant to embrace the technology since all of this companies are direct beneficiaries of the advances in machine learning. Take Tesla for example, where self-driving capability is one of the biggest value adds for its cars. Musk himself even believes that one day it will be safer to populate roads with AI drivers rather than human ones, though publicly he hopes that society will not ban human drivers in the future in an effort to save us from human error.What Musk is really pushing for here by being wary of AI technology is a more advanced hypothetical framework that we as a society should use to have more awareness regarding the threats that AI brings. Artificial General Intelligence (AGI), the kind that will make decisions on its own without any interference or guidance from humans, is still very far away from how things work today. The AGI that we see in the movies where robots take over the planet and destroy humanity is very different from the narrow AI that we use and iterate on within the industry now. In Zuckerberg’s view, the doomsday conversation that Musk has sparked is a very exaggerated way of projecting how the future of our technology advancements would look like.Related: The Future of Productivity: AI and Machine LearningWhile there is not much discussion in our government about apocalypse scenarios, there is definitely a conversation happening about preventing the potentially harmful impacts on society from artificial intelligence. White House recently released a couple of reports on the future of artificial intelligence and on the economic effects it causes. The focus of these reports is on the future of work, job markets and research on increasing inequality that machine intelligence may bring.There is also an attempt to tackle a very important issue of “explainability” when it comes to understanding actions that machine intelligence does and decisions it presents to us. For example, DARPA (Defense Advanced Research Projects Agency), an agency within the U.S. Department of Defense, is funneling billions of dollars into projects that would pilot vehicles and aircraft, identify targets and even eliminate them on autopilot. If you thought the use of drone warfare was controversial, AI warfare will be even more so. That’s why here it’s even more important, maybe even more than in any other field, to be mindful of the results AI presents.Explainable AI (XAI), the initiative funded by DARPA, aims to create a suite of machine learning techniques that produce more explainable results to human operators and still maintain a high level of learning performance. The other goal of XAI is to enable human users to understand, appropriately trust and effectively manage the emerging generation of artificially intelligent partners.Related: Would You Fly on an AI-Backed Plane Without a Pilot?The XAI initiative can also help the government tackle the problem of ethics with more transparency. Sometimes developers of software have conscious or unconscious biases that eventually are built into an algorithm — the way Nikon camera became internet famous for detecting “someone blinking” when pointed at the face of an Asian person or HP computers were proclaimed racist for not detecting black faces on the camera. Even developers with the best intentions can inadvertently produce systems with biased results, which is why, as the White House report states, “AI needs good data. If the data is incomplete or biased, AI can exacerbate problems of bias.”Even with the positive use cases, the data bias can cause a lot of serious harm to society. Take China’s recent initiative to use machine intelligence to predict and prevent crime. Of course, it makes sense to deploy complex algorithms that can spot a terrorist and prevent crime, but a lot of bad scenarios can happen if there is an existing bias in the training data for those algorithms.It important to note that most of these risks already exist in our lives in some form or another, like when patients are misdiagnosed with cancer and not treated accordingly by doctors or when police officers make intuitive decisions under chaotic conditions. The scale and lack of explainability of machine intelligence will magnify our exposure to these risks and raise a lot of uncomfortable ethical questions like, who is responsible for a wrong prescription by an automated diagnosing AI? A doctor? A developer? Training data provider? This is why complex regulation will be needed to help navigate these issues and provide a framework for resolving the uncomfortable scenarios that AI will inevitably bring into society.
