(PhysOrg.com) — Critics of the Space Program can utter a sigh of relief. Finally, an innovation with a good suds head on it. A colloborative effort between the Russian Academy of Science, Okayama University and Sopporo Breweries in Japan has developed a beer that uses 100-percent barley grown on the International Space Station. The barley was grown on the ISS during a five-month period along with lettuce, wheat and peas as part of a life-sustaining long term growing project.

Sopporo Breweries is not selling the 100-liters of Space Barley Beer it has created. Instead, 30 Japanese couples have been selected to taste Space Barley at a special event in Tokyo in January. Sopporo´s Junichi Ichikawa, a managing director of strategies for the brewery, says the Space Barley brand is unique insofar as it´s top Black Label brand uses additional ingredients like rice. Space Barley is made completely with the ISS barley. There is no commercially made beer like the Space Barley Brand. Beer is not included in the ISS menu due to the alcohol content and its potential for creating a gaseous product of digestion. Sopporo Brewery is hoping the Space Barley product could eventually become available for astronauts to sip a cool one while spending months aboard the space station. The news of the Space Barley Beer came about when it was discovered that a cargo of miso and mackerel, seaweed soup and green tea was sent to the International Space Station recently to sustain astronauts. According to a Russian cosmonaut, potatoes can be eventually grown on the ISS. He is quoted as saying, “pototoes can be grown for food, not for vodka production.” Sopporo Breweries is one of the oldest beer producers world-wide. It began in 1876 under a different name and under the direction of Seibei Nakagawa who studied beer making in Germany. The first beer label, Sopporo Lager reflects the Pioneer´s symbol, the Northern Star. © 2008 PhysOrg.com This document is subject to copyright.

The company is to invite on board some relevant industry partners, including NAND flash memory makers SanDisk, Micron, and Samsung. The goal is to explore a new SSD form-factor derived from mSATA. Reports are that Intel is harnessing PC manufacturers and storage specialists to work out a new storage standard, specifically, called the Next Generation Form Factor (NGFF).The standard mSATA SSDs set specific limits to the printed circuit board size, while the new NGFF would allow for larger printed circuit boards to be made. It is expected that the next generation of NGFF SSD for the 2013 Ultrabooks will feature the same width and thickness but will have a longer PCB.Intel’s recruits—Micron, SanDisk and Samsung Electronics—will help Intel to make Next Generation Form Factor (NGFF) better. Five length standards under consideration by Intel for the next generation of SSDs include 20mm, 42mm, 60mm, 80mm and 120mm.The NGFF will allow Intel to push beyond current limitations of 512 gigabytes of flash storage without changing the thickness or width of drives. According to reports, the 42mm, 60mm and 80mm are the likely sizes. Work on the specifications is expected to continue through September. The new drives will be on the market next year.The news comes none too soon for those familiar with the designs in question. The NGFF specs will allow disparate Ultrabook manufacturers to support a single SSD physical standard and will thereby make the industry a better environment overall, according to a recent article in The SSD Review. “I can’t imagine how many times an Ultrabook owner has cracked open their case in hopes of an upgrade, only to find that the SSD they want to swap out is in some obscure proprietary format, or worse yet, is soldered onto the motherboard.

Intel wants a new SSD connectivity standard because it needs to put to rest some issues with the mSATA standard. The latter stands for Mini-SATA, an interface connector. The current mSATA-specification SSDs used in Ultrabooks are limited in capacity. It is impossible to fit in more than four or six chips of NAND flash memory, and Ultrabooks would be limited to 512 GB of storage. Intel is not about to live with that limitation. © 2012 Phys.Org
Everlasting Quantum Wave: Physicists Predict New Form of Soliton in Ultracold Gases Copyright 2013 Phys.org All rights reserved. This material may not be published, broadcast, rewritten or redistributed in whole or part without the express written permission of Phys.org. The physicists, Alexander L. Gaunt, Richard J. Fletcher, Robert P. Smith, and Zoran Hadzibabic at the University of Cambridge in the UK, have published their study on the superheated BEC in a recent issue of Nature Physics.As the physicists explain, a superheated BEC is reminiscent of superheated distilled water (water that has had many of its impurities removed), which remains liquid above 100 °C, the temperature at which it would normally boil into a gas. In both cases, the temperature—as defined by the average energy per particle (boson or water molecule)—rises above a critical temperature at which the phase transition should occur, and yet it doesn’t. In BECs and distilled water, the inhibition of a phase transition at the critical temperature occurs for different reasons. In general, there are two types of phase transitions. The boiling of water is a first-order phase transition, and it can be inhibited in clean water because, in the absence of impurities, there is in an energy barrier that “protects” the liquid from boiling away. On the other hand, boiling a BEC is a second-order phase transition. In this case, superheating occurs because the BEC component and the remaining thermal (non-condensed) component decouple and evolve as two separate equilibrium systems.The physicists explain how this mechanism works in more detail. In equilibrium, a BEC can only exist below a critical transition temperature. If the temperature is increased towards the critical value, the BEC should gradually decay into the thermal component. The particles flow between the two components until they have the same chemical potential (a measure of how much energy it takes to add a particle to either component), or in other words, until they are in equilibrium with each other. However, maintaining this equilibrium relies on the interactions between the particles.

(Phys.org) —At very low temperatures, near absolute zero, multiple particles called bosons can form an unusual state of matter in which a large fraction of the bosons in a gas occupy the same quantum state—the lowest one—to form a Bose-Einstein condensate (BEC). In a sense, the bosons lose their individual identities and behave like a single, very large atom. But while previously BECs have only existed below a critical temperature, scientists in a new study have shown that BECs can exist above this critical temperature for more than a minute when different components of the gas evolve at different rates. Explore further Here, the researchers demonstrated that in an optically trapped potassium-39 gas the strength of interactions can be reduced just enough so that the two components remain at the same temperature, but the particle flow between them is slowed down and their chemical potentials decouple. This condition makes it possible for the BEC to maintain a higher chemical potential than the surrounding thermal component, and thus survive far above its equilibrium transition temperature.”The thing that prompted this work was a previous paper of ours on measuring the equilibrium BEC transition temperature as a function of the interparticle interaction strength,” Smith told Phys.org. “At the time we noticed that something funny was happening at very low interaction strengths: the transition temperature seemed higher than it should be by up to 5%. We realized that this was probably due to non-equilibrium effects, but could not explain it fully. Also, the effect was much smaller than we demonstrated now. Only after fully understanding the equilibrium properties of a BEC in an interacting gas we could come back to this problem, demonstrate a much clearer effect, and explain it quantitatively.”In the new study, the physicists experimentally demonstrated that a BEC could persist in the superheated regime (at temperatures above the critical temperature) for more than a minute. They also showed that that they could cause the BEC to rapidly boil away by strengthening the interatomic interactions to their normal levels, confirming the presence of the superheated state. The scientists predict that extending a BEC’s lifetime by tuning the interactions could have several applications.”Generally, atomic BECs are increasingly used for applications such as atom interferometry and precision measurements, and might also find applications in quantum information processing and computing,” Smith said. “For all those applications one wishes to preserve the coherent BEC for as long as possible, e.g., to perform a longer (hence more precise) measurement or more quantum-information type operations. Our work shows that it is possible to significantly extend the lifetime of a coherent BEC exposed to the experimentally unavoidable decohering thermal environment.”In the future, the researchers plan to further investigate the physical mechanism behind superheating.”We are primarily interested in further fundamental understanding of the superheating phenomenon,” Smith said. “The funny thing is that the system is simultaneously in equilibrium in some respects (e.g., the BEC and the thermal component have the same temperature, the BEC has an equilibrium shape for the given number of condensed atoms, etc.) and out of equilibrium in other ways (primarily the fact that the number of condensed atoms is much higher than expected in equilibrium). This poses new question about how we define equilibrium in a quantum system, which we would like to understand better. Practical applications might come later, fully exploiting their potential being reliant on more complete fundamental understanding. “Also, it turns out that condensation in 2D systems is even more interesting than in 3D, and we plan to study superheating and other non-equilibrium phenomena for an ultracold 2D Bose gas.”
Even before RHIC began operating in 2000, some people worried that the unprecedented experiment would pose risks of potentially catastrophic scenarios. Some of the concerns included the creation of a black hole or production of strange matter that could result in the destruction of the Earth, possibly within seconds. In 1999, before the collider opened, the media attention on the subject prompted BNL to form a committee of scientists to investigate the probability of such catastrophic scenarios. A few months later, the committee concluded that RHIC was safe. RHIC has now been running for nearly 15 years, and scientists have used it to make many fascinating discoveries, such as that of a quark-gluon plasma with a temperature of 4 trillion K. This liquid-like substance is unlike any kind of normal matter and recreates the conditions that existed during the first seconds of the universe.But due to budget cuts, in 2013 a government advisory panel recommended shutting down RHIC in the coming years as funding is put toward other projects. The US Consolidated Appropriations Act of 2014, passed just a few weeks ago, includes a provision for the establishment of a nine-member commission to evaluate the cost-effectiveness of all of the US national labs, including RHIC. It’s called the Commission to Review the Effectiveness of the National Energy Laboratories.According to Eric E. Johnson, Associate Professor of Law at the University of North Dakota, and Michael Baram, Professor Emeritus at Boston University Law School, this may also be a good time to reevaluate the safety risks at RHIC. They have written an opinion piece on the subject that is posted at International Business Times.Johnson and Baram are calling for the new commission to look into the risks of RHIC destroying the Earth in addition to evaluating the financial aspects. A large part of the motivation for their appeal is because of the ongoing upgrades to RHIC. The collider is preparing for its 14th run, where it will be operating at 18 times the luminosity for which it was originally designed. The high luminosity will enable scientists to conduct more detailed studies of the quark-gluon plasma’s properties and investigate how it transitions into the normal matter that we see in the universe today. Another area that Johnson and Baram argue begs some scrutiny is that RHIC is now running at lower energies than in the past. Somewhat counterintuitively, lower energies may pose a higher risk than higher energies. In the original risk assessment report in 1999, the scientists stated that “Elementary theoretical considerations suggest that the most dangerous type of collision is that at considerably lower energy than RHIC.” That assessment referenced RHIC’s original design energy of 100 GeV. Over the years, lower-energy experiments were performed, and the 2014 run will include three weeks at 7.3 GeV.Johnson and Baram are concerned that these changes might increase the possibility that the collider will generate strangelets, hypothetical particles consisting of up, down, and strange quarks. Some hypotheses suggest that strangelet production could ignite a chain reaction converting everything into strange matter.In their opinion piece, Johnson and Baram quote Sir Martin Rees, Astronomer Royal of the United Kingdom, who stated that the Earth would then become “an inert hyperdense sphere about one hundred metres across.”Along with other critics concerned with safety, Johnson and Baram are concerned that the original risk assessment in 1999 was biased because all of the committee members were either planning to participate in RHIC experiments or had a deep interest in the RHIC’s data. The diversity of the new commission may allow it to overcome that problem.Since the new commission will reflect a broad range of expertise in science, engineering, management, and finance, Johnson and Baram think that “this gathering of talent is a unique opportunity to ensure the RHIC gets the rigorous, independent risk analysis it has long warranted.””The luminosity upgrade, along with other evolutions of the RHIC program—including running collisions at different energies—suggests that the question of risk needs a fresh look,” Johnson told Phys.org. “For example, one of the reassurances given in the original safety report in 1999 was that the RHIC would run at a relatively high energy that would make strangelet formation less likely. But now the RHIC is being run at much lower energies. So, a re-evaluation is in order.”Bottom line, I can’t say whether or not the RHIC program is so risky that it should be shut down. But I do think it’s clear that the original safety assessment lacked independence and that it is now woefully outdated. The Commission to Review the Effectiveness of the National Energy Laboratories is an opportunity to look at the issue in a fair and complete way.”In the end, the dilemma raises the question of whether and how to perform unbiased low-probability, high-impact risk assessment for large science experiments—and whether it’s possible to achieve this feat in a way that satisfies everyone.

New protein nanoparticles allow scientists to track cells and interactions within them Scientists have studied animals, such as homing pigeons, that are able to use the Earth’s magnetic field to orient themselves, for quite some time, but have yet to uncover the actual mechanism behind the ability. In this new work, the researchers believe they may have found the underlying chemistry, even if they have not been able to connect it directly to magnetic sensing.The researchers picked up where other research left off—with a light sensing protein called cryptochrome that has been identified in the eyes of some animals–some have suggested it may play a part in magnetic sensing. But, because the protein is not sensitive to magnetism, the team reasoned that it might team up with another protein that is. To find out, they searched the genome of a fruit fly that is known to sense magnetic fields, until they found a gene responsible for creating a protein (called CG8198, which they renamed to MagR) that would respond to iron. They then polymerized that protein and coupled it with cryptochrome and then watched, using a microscope, what happened when iron objects were brought near. The team reports that the protein complex lined up like a needle in a compass.The researchers acknowledge that their findings do not prove that the protein complex is responsible for magnetic sensing, but suggest it seems possible—if the protein complex lined up inside the eye of a pigeon, for example, it could cause a reaction with other proteins or even cells, that in turn could impact nerve cells. They note that the protein complex exists in many organisms that have demonstrated magnetic sensing, including in the eyes of pigeons—they are calling on the research community to conduct other studies to determine if removing the complex from magnetic sensing insects or animals, causes them to lose their magnetic sensing abilities, which could indirectly prove that they form the basis for the ability. If such efforts prove fruitful, then the next logical step would be to study the complex further as it exists inside living animals to determine exactly how it works.

A magnetic protein biocompass, Nature Materials (2015). DOI: 10.1038/nmat4484AbstractThe notion that animals can detect the Earth’s magnetic field was once ridiculed, but is now well established. Yet the biological nature of such magnetosensing phenomenon remains unknown. Here, we report a putative magnetic receptor (Drosophila CG8198, here named MagR) and a multimeric magnetosensing rod-like protein complex, identified by theoretical postulation and genome-wide screening, and validated with cellular, biochemical, structural and biophysical methods. The magnetosensing complex consists of the identified putative magnetoreceptor and known magnetoreception-related photoreceptor cryptochromes (Cry), has the attributes of both Cry- and iron-based systems, and exhibits spontaneous alignment in magnetic fields, including that of the Earth. Such a protein complex may form the basis of magnetoreception in animals, and may lead to applications across multiple fields.

Stimuli-responsive microstructures are of key importance for the creation of adaptable systems, which can have interesting applications in soft robotics and biosciences. For practical application, however, materials need to be compatible with aqueous environments while also enabling the manufacturing of 3-D structures, for instance, using 3-D printing. “3-D printing by direct laser writing is a powerful technique enabling the manufacturing of almost all arbitrary stable structures in the micrometer range,” Marc Hippler, one of the researchers who carried out the study, told TechXplore. “However, for many applications, especially in the biomedical field, it is desirable to change the properties of the resulting microstructure on demand, as this enables the step from passive to active systems. We wanted to present a powerful and versatile technique to create such structures.” In order to achieve complex actuation patterns, researchers need to use materials that react differently to external stimuli, such as temperature and light. Hippler and his colleagues thus developed new 3-D hetero-microstructures based on N-isopropylacrylamide, a temperature-responsive monomer that is commercially available. Using their method, the researchers successfully created active structures that exhibit a large-amplitude response to changes in temperature. In addition, they showed that the response of these structures can be activated both globally, by changing the water temperature, and locally, by illuminating the desired microstructure with a laser focus.

Credit: Hippler et al. “We demonstrated a very versatile and powerful technique that can be employed and used by other people,” Hippler said. “I think three of the main aspects of our study are the creation of materials with largely different properties out of a single photoresist, the strong actuation due to a mild stimulus and the opportunity to use light to trigger the response. Due to this versatility, we didn’t focus on one particular application, but highlighted different possibilities.” In the future, these findings could inform the development of materials with applications in a variety of fields, including microfluidics, soft robotics and biosciences. Hippler will now continue working on this system, specifically focusing on biological experiments.”Additionally, we will be investigating other stimuli-responsive material systems with interesting properties that could be used for direct laser writing,” he said.

DOI: 10.1038/s41467-018-08175-w Journal information: Nature Communications “One important goal of our study was to achieve strong responses with a ‘mild’ stimulus,” Hippler said. “By increasing the temperature only slightly above room temperature we stay in a physiological range, which makes the system interesting for biological applications. One could, for example, think about single cells in 3-D scaffolds that are mechanically stimulated by their environment. We also demonstrated that this technique could be useful for other fields, such as microfluidics or soft robotics.”Hippler and his colleagues demonstrated that by changing the local exposure dose in 3-D laser lithography, the material parameters could be altered on demand. They then explored this possibility further to create 3-D architectures with large amplitude and complex responses.

Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAppreciating the Bengal government’s endeavour in giving a detailed memorandum in advance that helped them to get a clear picture on the state’s specific demands, Singh maintained: “The Bengal government has brought out very forcefully the need for the Finance Commission to look at the legacy issue of the debt overhang…and it could be redressed in a manner so that it doesn’t become a permanent drag on the economy of Bengal.”When asked about its reaction on the state’s demand for debt restructuring, the chairman said: “The views of the Finance Commission will be contained in the recommendations of the commission, which we will submit to the President of India. But a very robust presentation on the overhang of the debt issues was certainly very forcefully brought out both by the Chief Minister formally and in the detailed memorandum which was submitted to us.” The Chief Minister has maintained in the meeting that the last seven years have been challenging for Bengal, as ithas faced the legacy of huge debt burden and has repaid Rs 2.25 lakh crore in interest and principal and in the 2018-19 fiscal, it has to pay Rs 46,000 crore.Highlighting the revenue gap against the projected GST revenue in Bengal that was 33.4 percent in August 2017 and has registered a surplus of 3 percent by March 2018, the Chief Minister has also placed the demand that the share of the states in the divisible pool be increased from 42 to 50 percent and this comes when the revenue deficit grant is of Rs 90,136.48 crore.Singh also said: “We were also assured by the Finance minister that following detailed discussion with CSSO, anydiscrepancy with regard to the key macro-economic features has now been reconciled and it is expected that some time in August, the new figures based on the reconciliation with CSSO would be published.”
