By physically compressing a silicon waveguide – and thus allowing variations in the way light travels through the material – scientists have discovered a key to creating a silicon electro-optic modulator. This method could greatly decrease the cost of modern computers. Explore further Organic solar cells that last 10 years in space “Inside your computer, there are a bunch of small black components,” explains Rune Jacobsen, coauthor of a recent paper in Nature on strained silicon. “There is a silicon die inside each component, and it is in these chunks of silicon where all the ‘magic’ happens.”Silicon, considered the material of choice in electronics for decades, now has one more reason to be at the top. Scientists have observed electro-optical effects in silicon, which is the ability to convert electronic signals into optical signals. Previously silicon was thought to have limited optical properties due to its strong symmetrical traits and lack of an electro-optic coefficient.“We discovered a method that induces an electro-optic effect in silicon, which is done by deposition of a straining layer on top of the silicon crystal,” says Jacobsen. “The straining expands, and hence it deforms, the crystal structure of the silicon underneath [see figure]. This is not difficult, but until we made the discovery, it was not realized that you could make silicon electro-optically active by breaking the crystal symmetry.”The straining layer, composed of silicon nitride glass, compresses the silicon waveguide, a structure that guides light waves in the silicon. Using this straining method to break silicon’s crystal symmetry, the team has realized the possibility of using silicon to modulate a beam of light.The glass straining layer acts purely as a physical strain, asymmetrically compressing the silicon waveguide so that the waveguide expands horizontally. This physical change enables silicon’s bulk refractive index to vary linearly under the influence of an external applied electric field, creating electro-optic effects. “The index change is caused by a perturbation of the electron orbitals, which is the fastest physical process possible at room temperature,” says Jacobsen. “The time constant is typically lower than 10-15 seconds; i.e. the effect can be as fast as 1,000,000 GHz.”Another way to put it is that the electric field can slow the velocity of light waves in silicon due to the material’s broken symmetry. Once applied, the electric field can instantaneously determine whether or not light travels through a silicon modulator. “Such an electro-optic modulator is typically used when transmitting data, where transmitted light corresponds to a ‘1’ bit and no light to a ‘0’ bit,” wrote the scientists.This design differs from previous demonstrations of silicon modulators, which have used an electric current traveling through the silicon to achieve modulation. “In our demonstration, we use an electric field to achieve modulation instead of electric current,” says Jacobsen. “In 1987, Richard Soref et al. showed that you can make a modulator by leading an electrical current through the silicon and then changing the size of the current (ref: Soref, R. A. & Bennett, B. R. Electrooptical effects in silicon. IEEE J. Quant. Electron. QE-23, 123–129 (1987)). However, today, almost 20 years after the demonstration, you cannot buy commercial silicon components based on this technique, and it is still unsure if the technique is good enough for commercial use.”To negate the possibility of an electric current in this experiment, the scientists sandwiched a spacing layer made of silica glass between the silicon waveguide and the straining silicon glass on top. With this arrangement, no electric current travels through the waveguide. “The advantage to using silicon compared with other electro-optics materials is the price,” says Jacobsen. “If you can use silicon, the price will potentially become very low.”Citation: Jacobsen, Rune S. et al.

Motorized knee can make you run faster

first_img Overweight men at risk of osteoarthritis of both hip and knee 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 motorized knee comes in a 5 kg kit, part of which straps to your leg, and part of which (the control unit and battery) is worn as a backpack. The device is not designed to help people who are physically handicapped, but is designed to support the flex of the knee for people who just want to run more efficiently. The strap-on knee assistant allows runners to jog steadily at 7.5 km/h, but using 30% less muscle power than they would use for unassisted running. The researchers do not say how much of the saving in muscle power is offset by carrying the 5 kg weight of the gadget.The research team who developed the device is confident it will be commercialized within the next three years, and that there is a market for it. There are similar devices that help the physically handicapped walk, but the new gadget will be much smaller and lighter by the time it comes to market, and is intended for healthy people who just want to run more efficiently. Video: Robot suit HAL(Hybrid Assistive Limb) The motorized knee has a small motor that helps flex the knee, a sensor that detects the degree of flexing of the knee, and a safety lever.One apparent flaw in the idea seems to be that most joggers seem to jog precisely because they want to build up muscle power and get fit, and so the device would in effect mean they would have to jog for longer to get the same benefit to their fitness level. This may make the gadget a contender for next year’s “Ignobel” awards . It might possibly be useful for people recovering from a knee replacement or other knee operation, but if so, the researchers don’t mention the possibility, and have not designed it for rehabilitation or other medical purposes.Tsukuba University also developed the Robot Suit HAL, (Hybrid Assistive Limb) which is a cyborg-type robot that can help paralysed people learn to walk.

Water still has a few secrets to tell

first_img “Due to long range interactions, you can obtain a ‘solid like’ behavior in certain types of measurements for liquids,” Jan Swenson, one of the scientists on the project, tells PhysOrg.com. “These hidden slow dynamics has been suspected, but because they are impossible to observe straight on in dielectric measurements, they have been difficult to find. We are quite happy that we have come up with a method that can help us probe a little more deeply into the dynamical behavior of water and other liquids.” Swenson, and his colleagues, Helén Jansson and Rikard Bergman, have started to use a method demonstrating for the first time that water can exhibit a very slow relaxation process. Their results can be seen in Physical Review Letters: “Hidden Slow Dynamics in Water.”“It all started when we were studying protein solutions,” Swenson explains. “We used Teflon films to reduce conductivity and electrode polarization, and then measured the solvents and the proteins. We saw low frequency dynamics in the solvent, and saw that it was not due to the protein.” Swenson and his peers decided to see if it was perhaps due to the Teflon, but then saw it wasn’t, although the Teflon film plays an important role in identifying water’s hidden dynamics, due to its suppression of electrode polarization and conductivity. “Without a different way of analyzing this and using the Teflon film, it was practically impossible to see these dynamics.”For the most part, though, slow dynamics have a rather small effect. “This is a very weak feature,” Swenson concedes. “It does not dramatically change the behavior of liquids, but it is an interesting feature that could be of importance. Understanding it could be useful, at least in better understanding the structure and behavior of liquids.”Swenson thinks that these dynamics might apply to all hydrogen bonded liquids. “So far, it appears that this might be universal. We have been looking at different liquids, and have seen something similar. However, we have only tried it with hydrogen bonded liquids.” The next step, then, is to analyze liquids without hydrogen bonds. “We want to see if it has something to do with the hydrogen bonds. Are these dynamics related to the strength of the hydrogen bonds on the short range scale? We want to test as many liquids as we can to see the results.”In the end, it appears that there is more that we can learn from studying water, and its dynamics. “We always have a lot to learn, and it could prove helpful for our understanding,” Swenson says.

Researchers develop mRNA based flu vaccine

first_img RNA is a molecule that performs various functions in living organisms related to the regulation of expression of genes. mRNA is a type of RNA molecule whose function is to carry genetic information from DNA to the ribosome, which tells cells which proteins to manufacture. Introducing mRNA that has been preprogrammed to specify particular proteins into an animal or person can cause a predictable immune response – in this case targeting an infectious agent such influenza. The researchers report that their designer vaccine has demonstrated an ability to instill protective immunity in mice, ferrets and pigs.Currently, it takes up to six months to create and manufacture a flu vaccine; cultures of the virus are grown in chicken eggs and once mature are mixed with other ingredients to create a solution that can be injected into a person that causes their immune system to attack if the virus is ever detected in the body. Other new research has focused on cell cultures but that process also takes months. In contrast the new vaccine takes just six weeks to produce and the researchers report that thus far, it has shown itself to be just as effective as traditional vaccines in preventing flu symptoms.The researchers also report that the vaccine can be easily manufactured in large quantities and unlike other flu vaccines, doesn’t require refrigeration. They also noted in addition to providing immunity for averaged age animals, it also worked equally well in both very young and very old mice.To date, the team has tested the vaccine against several class A flu viruses, which include H1N1pdm09, swine flu and the H5N1 bird flu virus and have found it to be effective against all of them. It is not known yet if the same results might be found with its use in humans, though that the team reports, is the ultimate objective. More information: Protective efficacy of in vitro synthesized, specific mRNA vaccines against influenza A virus infection, Nature Biotechnology (2012) doi:10.1038/nbt.2436AbstractDespite substantial improvements, influenza vaccine production—and availability—remain suboptimal. Influenza vaccines based on mRNA may offer a solution as sequence-matched, clinical-grade material could be produced reliably and rapidly in a scalable process, allowing quick response to the emergence of pandemic strains. Here we show that mRNA vaccines induce balanced, long-lived and protective immunity to influenza A virus infections in even very young and very old mice and that the vaccine remains protective upon thermal stress. This vaccine format elicits B and T cell–dependent protection and targets multiple antigens, including the highly conserved viral nucleoprotein, indicating its usefulness as a cross-protective vaccine. In ferrets and pigs, mRNA vaccines induce immunological correlates of protection and protective effects similar to those of a licensed influenza vaccine in pigs. Thus, mRNA vaccines could address substantial medical need in the area of influenza prophylaxis and the broader realm of anti-infective vaccinology.

Inventor creates replica of Vermeer painting using modified camera obscura

first_imgThe Music Lesson by Johannes Vermeer © 2013 Phys.org New rheumatoid arthritis treatment shown to be effective: Half of all patients symptom-free within six months Explore further Citation: Inventor creates replica of Vermeer painting using modified camera obscura (2013, December 3) retrieved 18 August 2019 from https://phys.org/news/2013-12-inventor-replica-vermeer-camera-obscura.html (Phys.org) —Inventor Tim Jenison may have finally solved the mystery of how famed Dutch painter Johannes Vermeer was able to create paintings that so closely resembled photographs. His five year mission to learn Vermeer’s secrets has been filmed and a documentary made describing what he’s learned. More information: via VanityFair 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. Johannes Vermeer was a 17th century painter who stunned the world by suddenly appearing on the painting scene producing impressively realistic paintings, all seemingly without any training. Critics at the time suggested he “cheated” by using a device called a camera obscura, which is essentially a lens and mirror set up in a way to allow for better reference—it would be akin to painting using a photograph posted next to the canvas. The argument surfaced again in 2006 when modern painter David Hockney announced that the only way Vermeer could have painted the pictures he made, were by using some sort of mirror and lens contraption. The problem with the argument was that it couldn’t explain how the lighting could have come out the way it did—a mirror/lens device would have produced an image that was upside down.Shortly after Hockney’s announcement, millionaire inventor Tim Jenison became intrigued by the argument. His background was in optics, so it seemed a natural way to pass his time investigating the possibilities. Instead of a hobby, however, it became more of an obsession. Jenison traveled to Amsterdam to see an example for himself. He claims that led to an epiphany—one so strong that he learned Dutch so he could read original texts. He learned about early paints and how to make mirrors and lenses himself. Eventually, he even faithfully recreated the room and sunlight conditions of where Vermeer sat while painting “The Music Lesson,” one of his most famous pieces.As time passed, Jenison became convinced he had an inkling of how Vermeer pulled off his trick—he’d added another mirror to his camera obscura, causing the image it created to become right side up. By positioning a lens and two mirrors just right, he found he could create what would look like a photograph, just next to the canvas, allowing for simple replication of an actual setting. Putting all that he’d learned together, Jenison created what he believes are the conditions Vermeer was working under. And to prove his point, he even created a stunning painting of his own—one that very closely resembles “The Music Lesson.” He says, he’s 90 percent sure he’s solved the mystery. That last ten percent, he says, is there because he can’t figure out how Vermeer managed to hide the knowledge of his improved camera obscura.last_img read more

Researchers combine terra preta finds with statistics to map early Amazonian population

first_imgProbabilities of terra preta occurrence based on predictive models.. The black line indicates a potential cultural boundary where the probability of terra preta formation decreases and disappears and is replaced by alternative subsistence strategies in southwestern Amazonia. Credit: doi: 10.1098/rspb.2013.2475 (Phys.org) —A team of researchers from the U.S. and Brazil has created a virtual map of possible ancient human population centers in the Amazonian jungle by using statistical methods that connect modern terra preta areas. In their paper published in Proceedings of the Royal Society B: Biological Sciences, the team describes how they applied archeological site information with statistics to come up with a way to guess where other early population sites might be. Despite years of work, modern scientists still don’t really know much about the people that populated that Amazonian basin prior to the arrival of European explorers. The dense jungle growth has made it difficult to study the area, and the preponderance of poor soils suggests that the area could not have supported large groups of people anyway—the soil would not support the farming necessary to support them. In more recent times, some evidence (ancient roads and earthworks) has been uncovered that indicates that large settlements of people may indeed have indeed populated the area, which would have been made possible by a soil enrichment technique known as terra preta (adding nutrients that resulted in fertile “black earth” that can still be seen today.). Because very few terra preta sites have been found, researchers aren’t sure if they are few and far between, or if there are more simply hidden in the jungle. To find out, the researchers with this new effort created maps that displayed all of the known terra preta locations. They then noted geographical details about each site and discovered there were some possible correlations between them, e.g most tended to exist on bluffs overlooking rivers. Using such information, they applied statistical analysis to maps of the area and came up with a model that predicted where other terra preta locations may be found. Their results indicate that more than three percent of the total Amazonia basin may be hiding terra preta sites.The team has not been able to test their maps yet, so it’s not yet known how accurate their guesses may be, but the hope is that by uncovering more terra preta sites, more information can be gleaned from the area to help uncover chapters of human history in South America that until now have remained hidden.

Various indicators can be used to gauge the impact of pre-Columbian societies, but the formation of nutrient-enriched terra preta soils has been widely accepted as an indication of long-term settlement and site fidelity. Using known and newly discovered terra preta sites and maximum entropy algorithms (Maxent), we determined the influence of regional environmental conditions on the likelihood that terra pretas would have been formed at any given location in lowland Amazonia. Terra pretas were most frequently found in central and eastern Amazonia along the lower courses of the major Amazonian rivers. Terrain, hydrologic and soil characteristics were more important predictors of terra preta distributions than climatic conditions. Our modelling efforts indicated that terra pretas are likely to be found throughout ca 154 063 km2 or 3.2% of the forest. We also predict that terra preta formation was limited in most of western Amazonia. Model results suggested that the distribution of terra preta was highly predictable based on environmental parameters. We provided targets for future archaeological surveys under the vast forest canopy and also highlighted how few of the long-term forest inventory sites in Amazonia are able to capture the effects of historical disturbance.center_img Journal information: Proceedings of the Royal Society B Explore further Researchers find renewable energy leftovers could fertilize, cut carbon emissions Citation: Researchers combine “terra preta” finds with statistics to map early Amazonian population centers (2014, January 8) retrieved 18 August 2019 from https://phys.org/news/2014-01-combine-terra-preta-statistics-early.htmllast_img read more

Study suggests there are only two tiger subspecies

first_img Big cats are disappearing from the wild, with one of the most prominent being the tiger—they live on islands in and around Indonesia and on the Asian continent, from parts of Russia to Southeast Asia, and there is a big effort to save them. Up till now, there have been nine “official” tiger subspecies: Bengal, South China, Siberian, Sumatran, Malayan, Indochinese, Caspian, Bali and Javan. But these new researchers suggest that there are really only two subspecies: continental and sunda. The former would include all tigers living on the Asian continent, while the latter would include all those living on islands.The researchers came to this conclusion after conducting a study both of existing literature and of examples of tiger bones and other tiger parts in museums—more specifically they looked at bone structure, fur patterns and genetic makeup. They note that despite some genetic differences, there was just not enough evidence to separate continental tigers into different subspecies—the same held true for island tigers, though they do note that there was more than enough evidence to separate continental and sunda tigers.The team suggests that if others would accept their results, it might mean helping some of the more endangered tigers survive. South China tiger numbers are so low now, for example, that unless something big is done to save them, they will join Caspian, Bali and Javan tigers on the extinct list. They suggest introducing other continental tigers into the area, as was done in the U.S. to save the Florida panther—if they were considered to be the same subspecies than no dilution would occur.And added bonus of re-categorizing the tiger subspecies’ might be a reexamination of the entire system used to categorize animals and perhaps an overhaul resulting in a system that clearly defines where subspecies lines should be drawn. (Phys.org)—A team of researchers with affiliations to institutions in Germany, Denmark and the U.K. has concluded after extensive research, that there are really only two subspecies of tigers, as opposed to the nine that have been widely accepted for many years. In their paper published in Science Advances, the team describes their analysis of tiger similarities and differences and why they believe there are only two subspecies and why changing the classification could help save some of them. © 2015 Phys.org Citation: Study suggests there are only two tiger subspecies (2015, June 29) retrieved 18 August 2019 from https://phys.org/news/2015-06-tiger-subspecies.html This document is subject to copyright.

DOI: 10.1126/sciadv.1400175AbstractAlthough significantly more money is spent on the conservation of tigers than on any other threatened species, today only 3200 to 3600 tigers roam the forests of Asia, occupying only 7% of their historical range. Despite the global significance of and interest in tiger conservation, global approaches to plan tiger recovery are partly impeded by the lack of a consensus on the number of tiger subspecies or management units, because a comprehensive analysis of tiger variation is lacking. We analyzed variation among all nine putative tiger subspecies, using extensive data sets of several traits [morphological (craniodental and pelage), ecological, molecular]. Our analyses revealed little variation and large overlaps in each trait among putative subspecies, and molecular data showed extremely low diversity because of a severe Late Pleistocene population decline. Our results support recognition of only two subspecies: the Sunda tiger, Panthera tigris sondaica, and the continental tiger, Panthera tigris tigris, which consists of two (northern and southern) management units. Conservation management programs, such as captive breeding, reintroduction initiatives, or trans-boundary projects, rely on a durable, consistent characterization of subspecies as taxonomic units, defined by robust multiple lines of scientific evidence rather than single traits or ad hoc descriptions of one or few specimens. Our multiple-trait data set supports a fundamental rethinking of the conventional tiger taxonomy paradigm, which will have profound implications for the management of in situ and ex situ tiger populations and boost conservation efforts by facilitating a pragmatic approach to tiger conservation management worldwide.last_img read more
