first_img Currently, to keep track of a game, soccer fans have the option of reading textual information of the game’s key events in near-real-time, or listening to audio of the text transferred to voice. However, these options require a user’s full concentration and, as in the audio case, can be distracting to others. On the other hand, using vibrations to inform users where on the field the ball is being kicked, as well as which team has possession, could provide a discreet and easy way for users to follow a game while, say, walking down the street.The technology is being developed by a team of researchers consisting of Shafiq ur Réhman, Li Liu, and Haibo Li, all from Umeå University in Umeå, Sweden, along with Jiong Sun from Ericsson Research in Stockholm. The group’s study on their experiments and user tests will appear in an upcoming issue of IEEE Transactions on Multimedia.“Vibration could offer a ‘private’ channel and very efficient information encoding (even lower than SMS [short message service, or text messaging]),” Réhman told their method, a cell phone is synchronized with the ball in the real field, most likely through manual input. As the researchers note, the ball is the focus of most of the attention, which can be seen by TV cameras constantly following the ball. Every time the ball is kicked, the phone vibrates. Depending on where the ball is located on the field (which is divided into five segments), the phone vibrates at a specific frequency and duration. For example, when the ball is kicked in midfield, the phone produces a light, short vibration. When a player scores a goal, the vibration is stronger and longer. Depending on which team has the ball, the vibration is also different. In a more advanced version, the researchers plan to have a goal event trigger a switch to streaming video so users can watch an instant replay. (Streaming an entire game would require a very large amount of power for mobile devices.)“How to design ‘intuitive’ vibration patterns (a kind of ‘Braille codes’) to represent dynamic game information – that is the most challenging part of making the vibrotactile technique easy and informative for users,” said Réhman.In user tests, the researchers found that participants could follow the game based on the vibrotactile method sufficiently easily and quickly for the method to be interesting. After an initial experience with the technique, participants received brief training by watching a soccer game and experiencing synchronized vibrations. In post-training tests, participants demonstrated greater accuracy at following the games, although the average efficiency decreased because participants spent more time thinking about the signals after training.Although rendering rich information, such as soccer games, by vibration on mobile phones is rather new for researchers and users, most participants responded positively to the vibrotactile concept of live game information. In the future, the researchers hope to integrate vibration with visual and audio information to integrate the three basic senses of touch, sight, and hearing, in order to give users a richer emotional experience. Réhman added that, in the future, the technology will be commercialized by the Umeå-based spinoff company, Videoakt AB ( information: Shafiq ur Réhman, Jiong Sun, Li Liu, and Haibo Li. “Turn Your Mobile Into the Ball: Rendering Live Football Game Using Vibration.” IEEE Transactions on Multimedia.

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. Most everyone knows by now about the problems with carbon dioxide in the atmosphere—most agree that it’s causing global warming. But there is another greenhouse gas that is also of concern: methane. Though it doesn’t stay in the atmosphere as long, it’s better at blanketing the planet, causing warming. For that reason, scientists and governments attempt to monitor how much is being emitted into the atmosphere due to manmade actions so that plans for reducing it can be put into place. The prime culprits are the oil and gas industry, and livestock (though likely a significant source, amounts of methane emitted by human flatulence is not counted.) In this new effort, the researchers have found that the actual amounts being emitted by both sources in the U.S. don’t match what the government has been reporting.Back in 2004, the ENVISAT satellite with a special sensor aboard took measurements of gasses in the atmosphere across the planet. The researchers used that data to create a map of methane emissions all across the U.S., focusing most specifically on areas where high volumes of methane emissions could be seen. They compared their map with other maps created by other teams using data collected from airplanes and found agreement in areas covered by the planes. In comparing what they found with data supplied by the EPA, however, the researchers found differences in the amounts reported for both livestock and the oil and gas industry.Specifically, the researchers found satellite data showed livestock emitted 13 million tons of methane over the summer in 2004 (the EPA reported 9.7 million tons). They found the satellite data also showed that the combined emissions of the oil and gas industry amounted to 7 million tons (the EPA reported 9.9 million tons).Unfortunately the sensor on the satellite was unable to show methane amounts after 2004, thus more data is not available. That will change soon however as a new satellite with sophisticated atmospheric gas monitoring sensors aboard is set to launch next year. Explore furthercenter_img Journal information: Journal of Geophysical Research – Atmospheres Analysis of data received from a satellite in 2004 has shown that at least during that year, livestock in the U.S. emitted more methane into the atmosphere than did the oil and gas industry. In their article published in Journal of Geophysical Research: Atmospheres, a team of researchers from Harvard University, California Institute of Technology and the University of California studying the data note that such emissions were far higher than was reported by the U.S. Environmental Protection Agency (EPA).

first_img Sediments in Gulf of Naples reveal impact on Roman water distribution after Vesuvius eruption © 2017 A small team of researchers from France and the U.K. has found evidence of lead pipe construction by the early Romans in soil samples taken from harbors near ancient Rome. In their paper published in Proceedings of the National Academy of Sciences, the group outlines their study, which included extracting core samples from Ostia and Portus harbors and analyzing them. The ancient Romans were well known for their water management techniques. Many of the aqueducts they built to carry water from nearby mountains to Rome still remain today. But the Romans also developed innovative techniques to distribute the water once it reached the city and for carrying sewage from the city to nearby ocean harbors for dumping. Prior research has shown that the water was carried by terracotta or wooden pipes during some time periods. But there was also a period when lead pipes were used, and the researchers with this new study have found further evidence of them.To find evidence of the lead pipes, the researchers drilled down into 177 sites at the nearby Ostia and Portus harbors, pulling sediment samples from each. They then carbon dated the cores and subjected them to chemical analysis. In so doing, they were able to date the various layers of sediment in the harbor and the amount of lead in each.The team reports that lead levels in the sediment spiked at around 200 B.C. and remained high until around 250 A.D. This, they suggest, indicates that lead pipes used by the Romans were the likely source of the lead contaminants in the harbor soil. Their assessment also suggests that the Romans began using lead piping approximately 150 years earlier than prior studies have shown. The timing of introduction of lead piping would then have come approximately 150 years after the Romans began using the aqueduct system. They note also that the timing of the reduction of lead levels in the sediment coincides with the empire’s Imperial period—a time during which civil wars were raging, making it impossible to maintain the extensive plumbing system.The findings are expected to offer insight into the timeline of events in ancient Rome, and perhaps establish whether the use of the pipes resulted in lead poisoning among the people of the city, including its leaders.

first_img Markers of diet and behaviour in chimpanzee dental calculus More information: Multiproxy evidence for leaf-browsing and closed habitats in extinct proboscideans (Mammalia, Proboscidea) from Central Chile. PNAS. are so-called ecosystem engineers and are considered key players in hypotheses about Late Pleistocene megafaunal extinctions. However, knowledge about the autoecology and chronology of the proboscideans in South America is still open to debate and raises controversial views. Here, we used a range of multiproxy approaches and new radiocarbon datings to study the autoecology of Chilean gomphotheres, the only group of proboscideans to reach South America during the Great American Biotic Interchange (∼3.1 to 2.7 million years before present). As part of this study, we analyzed stable isotopes, dental microwear, and dental calculus microfossils on gomphothere molars from 30 Late Pleistocene sites (31° to 42°S). These proxies provided different scales of temporal resolution, which were then combined to assess the dietary and habitat patterns of these proboscideans. The multiproxy study suggests that most foraging took place in relatively closed environments. In Central Chile, there is a positive correlation between lower δ13C values and an increasing consumption of arboreal/scrub elements. Analyses of dental microwear and calculus microfossils have verified these leaf-browsing feeding habits. From a comparative perspective, the dietary pattern of South American gomphotheres appears to be constrained more by resource availability than by the potential dietary range of the individual taxa. This multiproxy study is aimed at increasing knowledge of the life history of gomphotheres and thus follows an issue considered one of the greatest challenges for paleontology in South America, recently pointed out by the need to thoroughly understand the role of ecological engineers before making predictions about the consequences of ecosystem defaunation. © 2018 Although world-famous consulting detective Sherlock Holmes prided himself on his deductive prowess, in truth, a great many of his astounding observations resulted from inductive reasoning, by which he arrived at conclusions about events that he did not observe based on the evidence at hand. Similarly, biologists, ecologists and paleontologists strive to describe the world that existed before humans could observe or record it, based only on fossil information. Via induction, they attempt to reconstruct the prevailing climate during biological epochs, the dietary habits and behaviors of extinct animals, and the lineages of creatures for which sparse fossil evidence is available.

B.P.” Explore further A warm and dry environment from the Tagua Tagua site (North Central Chile, Pleistocene / Holocene) Credit: Martín Chávez (artist). When Holmes examines the scene of a crime, he observes everything around him to collect multiple data points from which to draw conclusions. Modern paleontology might describe this as a multiproxy methodology, in which the analysis is complemented by multiple sources of information. A recent multiproxy analysis by an international collaborative of researchers has produced a vivid picture of the dietary habits of extinct proboscideans in Central Chile, thereby also informing a picture of South American microclimates that Holmes might approve of.Gompotheres were elephant-like mammals that lived 12 to 1.6 million years ago during the Miocene and Pliocene epochs. Chilean gompotheres were the only group of proboscideans to reach South America, and survived to the end of the Pleistocene. Biologists refer to gompotheres as “ecosystem engineers,” animals that significantly modify their habitats. They strongly affect species richness and geographic heterogeneity within their domains.Paleontologists have recognized an array of dietary categories based on the dental morphology evidenced in fossils, including browsing, grazing and mixed feeding. However, because dietary patterns are strongly influenced by the environment, dental morphology alone may not provide enough evidence to draw conclusions about dietary habits. For the current study, the researchers analyzed multiple points of evidence to determine the diets of Chilean gompotheres, including stable isotopes, dental microwear, and dental calculus microfossils derived from molar fossils found at 30 Late Pleistocene sites. Gompotheres have previously been classified as browsers based on their dental morphology. Browsers favor soft shoots, fruit and leaves, by contrast with grazers, which eat grass and ground vegetation. But consider modern elephants, which have grazing dental morphology. The authors observe that elephants are mixed-feeders, with a tendency toward browsing. The multiple sources of evidence, with heavy weight on the decay of the isotopes present in the samples, led the researchers to the conclusion that most of the feeding took place in closed environments. They also conclude that the diet of gompotheres was more influenced by resource availability than by potential dietary range. However, samples from North Central Chile had evidence of an exclusive leaf-browsing environment. This reflects the environmental variability of the transition from the Pleistocene to the Early Holocene. One Querero specimen had evidence of an open, dry environment, and was particularly valuable to the multiproxy analysis—although dental microwear and dental calculus microfossil analysis suggested it was a leaf browser, the bulk of the evidence favored the conclusion that it lived in a more arid environment in which woodland and shrub striatum were predominant. The researchers believe that their approach prevents misleading conclusions that can be drawn from single sources, and that it is highly applicable to the study of such biologically rich regions as South America. The study, titled “Multiproxy evidence for leaf-browsing and closed habitats in extinct proboscideans (Mammalia, Proboscidea) from Central Chile,” is published in the Proceedings of the National Academy of Sciences.last_img read more

Scale = 10 cm. Credit: PeerJ (2019). DOI: 10.7717/peerj.6614 Mastodon were large animals that resembled modern elephants. They existed during parts of the Miocene and Pleistocene epochs, and were related to mammoths. They have been extinct for approximately 3000 years. Scientists have known of their existence for approximately 200 years—and they have been studied extensively, which makes the discovery of a new species very much a surprise.The new discovery did not come about due to a new dig—indeed, the bones that gave evidence of the new species have been held in several museums throughout California for over 20 years. The discovery was accidental—some of the team members were doing a study of mastodon teeth and found differences between the samples in California and those that were from other parts of North America. Those in California had molars that were smaller and less wide compared to those from mastodons in other places. This finding prompted the team to take a closer look, which revealed that the specimens also had more vertebrae, lacked a lower tusk and had femurs that were somewhat different.The California fossils were found at Diamond Valley Lake in the 1990s, where 100,000 skeletal fossils were unearthed—the area is now covered over by an emergency water reservoir, so it is unlikely that more will be found. The researchers note that in addition to the obvious physical differences, there is evidence that the animals living in California were isolated from other species for thousands of years, and that they lived during the Pleistocene. They suspect there are also genetic differences. The researchers claim that the cumulative evidence strongly points to the discovery of a new species, making it the first new North American mastodon species reported in 50 years. Other researchers will have to review the work and conduct studies of their own before the new find can be officially recognized as a new species: Mammoth pacificus.

In their paper published in the journal Science Advances, the group describes their new type of carrier and how well it worked with test mice. © 2019 Science X Network The upconversion nanoparticles convert near-infrared light into ultraviolet light, inducing the cleavage of linker and triggering the on-demand release of Cas9 with subsequent gene edting. Credit: Yujun Song, Nanjing University CRISPR-Cas9 gene editing tools are a coming revolution in treating genetic conditions, and scientists continue to test their abilities in a variety of applications. One area of study has involved looking for a replacement carrier system—the current approach uses a virus to carry the gene editing tool into a particular cell. Early on, researchers knew that the virus approach was not viable because of possible responses from the immune system, or worse, the threat of initiating tumors. In this new effort, the team in China has come up with an entirely new way to deliver the gene editing tool using two kinds of light.Their carrier system consists of nanoparticles that are sensitive to low-energy near-infrared radiation (NIR) and that emit UV light. When NIR is shone on the nanoparticles, the light is absorbed and converted to UV light, which is emitted. Inside of a cell, the package is activated by shining NIR onto the skin, where it penetrates into the body and makes its way to the gene editing tool. When the NIR is converted to UV light, it cuts molecules in the carrier package, releasing the gene editing tool to do its work.In practice, a CRISPR-Cas9 tool was delivered directly by the team to a cancer tumor inside of a mouse via injection. When it was safely in place, the researchers shone NIR on the skin covering the location where the tumor (and gene editing tool) was located. When UV light released the package, it went to work editing a protein that allowed a tumor to grow—the end result was a reduction in tumor size.The researchers suggest their work shows not only that a light-based carrier can work with CRISPR-Cas9 gene editing, but that it can do so safely and with direct benefits.
