ShareTweetSharePinThomas LetangGeneral Secretary of the Dominica Public Service Union (DPSU), Thomas Letang has said that PSU members have the right to select candidates who are best equipped to manage the affairs of the country.Speaking at news conference on Thursday 9th May, 2019, Letang said two brochures have been created to re-enforce DPSU’s democratic values.“As a union, we believe we have a right, not to tell our members who to vote for, but we have a right to provide some guidelines to our members,” he said.“Therefore, we have prepared a brochure which is written as part of the effort to PSU to re-enforce our democratic values for creating interest in the issues involved in voting and to help the Dominican people who are eligible to vote to exercise that duty with care, integrity and confidence,” Letang stated.He elaborated, “Public sector employees and citizens in general must cast their vote for leadership that is committed to making their life better by showing willingness to address issues aimed at national development. Better salary and wages and improved working conditions should be given priority. ” he said. “Vote a government which is willing to listen to, and respect your union and to negotiate in good faith and within reasonable time. It is wrong to accept bribes for your vote. Your government should be willing to address the problem of large numbers of public officers who have not been appointed after many years in this service.”Letang said politics affects every conceivable aspect of Dominica’s development and encouraged a free and fair general election.Letang pointed out that the minimum wage of Dominica has been the same for the past 21 years and has been trying to get this matter of salary negotiations to begin, stating that the only development made in that regard was the letter of acknowledgement of their proposals to the government.He said that on numerous occasions letters have been written to the relevant authorities and the prime minister of the various issues that affect public officers. “As far it applies to nurses, transportation to work, security concerns, concerns at the Princess Magret Hospital (PMH) and various health centers, teachers, the questions of appointment, fire officers’ appointments, conditions of work, protective equipment, building conditions, poor living conditions, the question of salaries and the list goes on,” Letang explained.The PSU General Secretary went on to say that the Prime Minister has been meeting with public officers to discuss “personal matters” without the PSU general body stating that it is “unheard “of in the history of the Caribbean that any Prime Minister can function as an employer of the public service.Members of the PSU will hold a briefing on May 23rd , 2019 where decisions will be made on their next course of action.

Reviewed by James Ives, M.Psych. (Editor)Dec 14 2018New research from Seattle Children’s Research Institute and UW Medicine’s Sports Health and Safety Institute found concussion rates among football players ages 5-14 were higher than previously reported, with five out of every 100 youth, or 5%, sustaining a football-related concussion each season.Published in the Journal of Pediatrics, the study summarizes the research team’s key findings from data collected during two, 10-week fall seasons in partnership with the Northwest Junior Football League (NJFL). Licensed athletic trainers from Seattle Children’s treated and recorded concussion from the sidelines at NJFL games to allow researchers to characterize concussions in this age group – from how often players sustained a head injury to factors that influenced their risk of injury.”Measuring the incidence of concussion in grade-school and middle-school football players is essential to improving the safety of the game,” said Dr. Sara Chrisman, an investigator in the research institute’s Center for Child Health, Behavior and Development and lead author on the study. “It’s hard to determine the impact of prevention efforts if we don’t know how often these injuries occur at baseline.”Getting accurate data in a difficult to track age groupPart of the reason prior studies may have underestimated the incidence of concussion in youth football by as much as 4% is because they relied on incomplete injury reports from team managers, coaches or other data sources. Despite an American Academy of Pediatrics recommendation that athletic trainers provide medical coverage for youth football, the use of athletic trainers is not as prevalent in grade-school and middle-school football leagues. It is likely that some youth with concussion in this age group go undiagnosed in the absence of a medical professional on the sidelines.To provide a more accurate snapshot of concussion incidence, the current study provided licensed athletic trainers for medical surveillance at all NJFL league games and practices during the 2016 and 2017 seasons. The athletic trainers helped researchers identify 51 football-related concussions among the 863 youth they followed as part of the study, with 133 of those players participating in the study for two seasons.In addition to reporting on concussion incidence, researchers found two-thirds of concussions occurred during games, almost half from head-to-head contact. Follow-up surveys found a history of prior concussion was associated with a two-fold greater risk of concussion, and a history of depression was associated with a five-fold greater risk of concussion.”We’re just starting to piece together how factors such as prior injury or depression may contribute to a child’s risk of concussion. Our study revealed patterns about who was most at risk for concussion, and these are areas we hope to explore in future studies,” said Chrisman, who is also an assistant professor of pediatrics at the University of Washington School of Medicine.Related StoriesResearchers identify gene mutations linked to leukemia in children with Down’s syndromePerinatal depression screenings may overlook women having suicidal ideationRevolutionary gene replacement surgery restores vision in patients with retinal degenerationResearchers found most youth returned to school within a few days, but half took longer than 13 days to return to sport and longer than three weeks to return to baseline symptoms.Youth concussion hits home for one familyAndrew Ronneberg, 14, is a naturally gifted quarterback and cornerback for the NJFL’s North Creek Jaguars.His mom, Tonya Ronneberg, has always invested in the latest equipment to give him extra protection on the field – from built in sensors that detect hard hits to purchasing Andrew his own helmet since age 8. When Andrew experienced a concussion during a game in the 2017 season, Ronneberg was glad a Seattle Children’s athletic trainer was on the sideline.”An opposing player had grabbed Andrew by the arm and flung him to the ground, causing him to land on his head hard,” she said. “The athletic trainer saw it right away and took him out of the game.”After seeing a sports medicine specialist the next week, Andrew stayed home from school for a few days and missed the rest of the football season. He didn’t mind taking the online follow-up surveys that were part of the research study and returned to play for the Jaguars in the 2018 season.”We felt it was important to participate in the study because no one else had captured information on players like Andrew before,” Ronneberg said. “When you start following players at a young age and continue to gather information through high school and college, you create a more detailed history that can help researchers better understand concussions in football players.”More research needed to promote safe playRecreation and sports related concussions affect up to 1.9 million youth in the U.S. each year. Led by Dr. Frederick Rivara, the director of the Seattle Pediatric Concussion Research Collaborative and professor of pediatrics at the University of Washington School of Medicine, the NJFL study is one of several studies underway at Seattle Children’s dedicated to improving understanding of youth concussion and finding better ways to prevent, diagnose and treat it.”This study lays the groundwork for new efforts to prevent head injuries in youth football,” said Chrisman, who also leads research using pre-game safety huddles to promote safe play. “Making sports safer for youth is at the core of our research.”Source: https://pulse.seattlechildrens.org/new-findings-on-concussion-in-footballs-youngest-players/
Apr 24 2019Texting patients with schizophrenia and their lay health supporters in a resource-poor community setting is more effective than a free-medicine program alone in improving medication adherence and reducing relapses and re-hospitalizations, according to a study published April 23 in the open-access journal PLOS Medicine by Wenjie Gong of Central South University in Hunan, China, Dong (Roman) Xu of Sun Yat-sen University Global Health Institute, Guangdong, China and colleagues. Credit: Marco Verch, Flickr Source:https://www.plos.org Schizophrenia is a leading cause of disability and, in low- and-middle-income countries, the treatment gap remains high; even when treatment is available, adherence to antipsychotics is low. Mobile phone text messaging has been shown to be useful to strengthen community- and family-based care in resource-poor settings due to its availability, reliability, and ease of use. But there has been no clear evidence that texting improves treatment adherence, symptoms or functioning in people with schizophrenia. Gong and colleagues hypothesized that mobile phone texting could improve schizophrenia care in resource-poor community settings compared with a free-medicine, community-based program alone. To test this idea, the researchers developed an intervention called LEAN (Lay health supporters, Electronic platform with mobile texting for medication reminders, health education and monitoring, Award of token gifts for positive behavioral improvement, and integration into health systems).Related StoriesResearchers explain how ‘viral’ agents of neurological diseases ended up in our DNAExploring how schizophrenia and depression are related to drug consumptionResearchers find new physical evidence in the brain for types of schizophreniaIn this randomized controlled trial, 278 community-dwelling villagers with schizophrenia in Hunan, China were randomized into two groups. Both groups received a nationwide community-based mental health program that provided free antipsychotic medications, and participants in the intervention group also received LEAN, which featured a lay health supporter and text messages for medication reminders, health education, monitoring of early signs of relapses, and facilitated linkage to primary health care. The results showed significant improvement in medication adherence with a mean of 0.48 in the control group, where 1 represents complete adherence in the past month, as compared with 0.61 in the intervention group at 6 months (adjusted mean difference 0.12 [95% CI 0.03–0.22, p=0.013]). This 27% relative improvement is larger than the 15–18% range reported for other text-message interventions. Moreover, there was an apparent reduction in the risk of relapse in 34.2% (40 of 117) control participants as compared with 21.7% (26 of 120) interventional participants, and a decrease in re-hospitalizations in 20.5% (25 of 122) controls as compared with 7.3% (9 of 123) interventional participants. According to the authors, texting was able to effectively address low medication adherence at marginal cost in rural China, and further research could investigate the LEAN program for potential benefits in people with schizophrenia in other low- and-middle-income countries with resource constraints.

(Editor)May 9 2019A new Journal of Diabetes study from China, which has the highest number of people with diabetes among all countries, found that type 2 diabetes was linked with an elevated risk of 11 types of cancer in men and 13 types of cancer in women.The possible association between diabetes and cancer risk has long been speculated, but previously reported findings have been inconsistent. In the largest study to date concerning the association between type 2 diabetes and cancer risk in mainland China, investigators examined information from the Shanghai Hospital Link database. They identified 410,191 adults with type 2 diabetes (and without a history of cancer) from July 2013 to December 2016.

Comcast says it’s dropping out of the bidding war for Twenty-First Century Fox’s entertainment business, instead focusing on its bid for Sky. (AP Photo/Matt Rourke, File) Comcast had been dueling with Disney for Twenty-First Century Fox, but Comcast said Thursday that it would not raise its $66 billion offer for Fox. The Walt Disney Co. had topped Comcast’s bid by offering $71 billion.The U.S. Department of Justice has approved Disney’s bid as long as Disney, which owns the national sports network ESPN, sells Fox’s 22 regional sports networks. Fox shareholders are set to vote on Disney’s offer July 27. Explore further Disney CEO Bob Iger said he was “extremely pleased” with Comcast’s announcement.”Our focus now is on completing the regulatory process and ultimately moving toward integrating our businesses,” he said in a statement.GBH Insights analyst Daniel Ives said called Comcast’s move “the final chapter in this soap opera.” He said Comcast’s focus now is on getting Sky “to build a strong beachhead content strategy in Europe.”Sky operates in Austria, Germany, Ireland, Italy and the U.K. It has 22.5 million customers, attracted by offerings such as English Premier League soccer and “Game of Thrones.”Fox has been trying to buy the 61 percent of Sky it doesn’t already own. The idea was to sell Sky to Disney as part of the broader deal. Last week, Comcast made a bid that values Sky at $34 billion, compared with $32.5 billion in Fox’s offer.Disney said in a regulatory filing last week that Fox might not raise its bid to compete with Comcast’s offer, meaning Comcast is likely to end up with Sky and Disney the rest of Fox that’s up for sale.

Citation: Comcast drops Fox bid, paving way for sale to Disney (2018, July 19) retrieved 18 July 2019 from https://phys.org/news/2018-07-twenty-first-century-fox-comcast.html Comcast can now focus on its pursuit of European pay-TV operator Sky, a deal that would give the Philadelphia-based cable and media company a larger presence outside the U.S.The moves come as the media landscape is shifting dramatically. Cable and telecom companies are buying content makers to compete with popular streaming services such as Netflix and Amazon. These emerging services are both creating their own content and distributing it outside of traditional cable and TV networks. Although internet providers like AT&T and Comcast directly control consumer access to the internet in a way that Amazon, YouTube and Netflix do not, they still face threats as those streaming services gain in popularity.Big media companies now want to control all aspects of TV shows and movies that people watch, from creating the videos to distributing them though television channels, movie theaters, streaming services and other ways people watch entertainment. Controlling the process this way helps companies gather valuable data on their customers and their entertainment-consuming habits, which they can then use to sell advertising.AT&T bought Time Warner last month for $81 billion and has already launched its own streaming service, called Watch TV, with Time Warner channels such as TBS and TNT, among other networks, for $15 a month.Disney has its own streaming service in the works, and the addition of Fox’s movies and shows would help boost that offering. Disney owns Marvel Studios, but some characters including the X-Men had already been licensed to Fox. A sale means the X-Men and the Avengers could reunite in future movies.If the deal closes, Disney would also get a controlling stake in the existing streaming service Hulu.
Citation: From Echo Auto to Alexa: Hits and misses from Amazon’s new product reveal (2018, September 24) retrieved 17 July 2019 from https://phys.org/news/2018-09-echo-auto-alexa-amazon-product.html The Echo speakers got the most attention. And pundits had fun with a talking Alexa microwave and clock. Here’s a $50 dongle that plugs into any car USB port. Where do we sign up? (Amazon is making the Auto tool available to “invite-only” customers for $24.99 and eventually will release it to the public for $49.99)Of the speakers, Amazon spent much of its presentation touting prettier speakers (the Dot and Echo Plus have more style this year), but the device that’s getting the biggest push is the revamped Echo Show.This is the Echo speaker with a video monitor that started slowly when it was first introduced in 2017. The original Echo had a small 7-inch video screen, and while it originally cost $229, you can pick up the older model now for $129.99.The new Echo has a 10-inch screen, improved speakers and a beefier body. Going from 7 inches to 10 inches doesn’t sound like much, but trust me, this is a huge move that will be noticed in kitchens from here to Paris.What the Echo Show now looks like is a megacomputer, a fat iPad, with a beautiful screen that could eliminate computer use or the kitchen TV for many people. And it makes video phone calls, shows lyrics from songs and lets you share your photos. That would improve life for many people—passing around the phone to view pictures is getting boring.The knock on the Show when it launched is that there was little video available for viewing. At first, Google’s YouTube was available, until a corporate spat saw Google remove it. So now Amazon has a workaround—a web browser, to watch YouTube or other online video sites.And taking us full circle, the new Recast has more functionality than say, my DVR in that video recorded can be viewed in multiple places—the TV, phones, tablets and, of course, the Echo Show. Again, turning the Show into the small family TV.If there were any losers from the event, it would have to be classic Echo speakers. More stylish, better sound, so Amazon says, but compared to a talking microwave, a TV replacement for the kitchen, an affordable DVR for cord cutters and the ability to have Alexa join us on car rides, the plain, basis Echo just seems so … yesterday.Unless we’re whispering to it, right? Alexa, send up breakfast: Amazon launches Echo for hotels Explore further But the DVR and auto stick stole Amazon’s new product launch show, hands down.Amazon invited a handful of journalists to its headquarters here Thursday to show off its new line of holiday products, which will be available in October and November.The updated portfolio of Echo-connected speakers have better sound, improved aesthetics and useful tools. I love the new whisper trick—speak softly to Alexa and she will speak softly back to you.But I spend more time watching TV than I do whispering. And not a day goes by that I’m not usually driving.In terms of being useful, the hits from the presentation came when Amazon hit us where we live. —The Fire TV Recast DVR is a consumer-friendly machine for cord cutters, a way to finally record our favorite TV shows (very few DVRs are available for this) without a pesky monthly fee. Recast starts at $229—period. Compare this to the granddaddy of DVRs, TiVo, whose Bolt box is $199, plus $15 monthly for service. (And most cable operators charge around $20 to $30 monthly to rent their DVRs.)Spoiler alert: The Recast is strictly for cord cutters. It doesn’t work with cable boxes but instead with home antennas, answering a need for those who watch broadcast shows but don’t have a way to tape them. —The Echo Auto is an ingenious little device, the size of an old iPod Nano, that plugs into the USB port in your car and your phone. Voila, you now have Alexa in the car.I have Bluetooth in my Hyundai Elantra and can make calls and little else. I can’t ask for on-demand music or podcasts, I can’t request directions or local restaurants.So I welcome this $50 device that could do all of that, plus all those Alexa skills that theoretically would work in the car.Alexa, find me the nearest gas station.Alexa, where’s the closest McDonald’s?Alexa, how many miles away is the nearest motel?Those are things all of us need.Sure, there are auto alternatives out there, most notably Apple’s CarPlay and Android Auto, but they are add-ons you buy with a new car purchase or as after-purchase accessories, costing from $299 to $399, plus installation. ©2018 USA Today Distributed by Tribune Content Agency, LLC.

Smart motorways can reduce the speed limit to manage congestion. Credit: Bill Boaden, CC BY-SA Provided by The Conversation Citation: Increasing the speed limit won’t get the traffic moving faster (2018, October 5) retrieved 17 July 2019 from https://phys.org/news/2018-10-limit-wont-traffic-faster.html One argument for increasing the speed limit is that it – and most roads – were designed for a different generation of vehicles. Every road has a design speed, defined as the rate at which 85% of drivers choose to travel in free flow conditions. Design speeds in current UK standards range from 50km/h (31mph) to 120km/h (75mph) depending on the type of road. A road’s design speed isn’t necessarily the same thing as the legal speed limit.The road is then built to ensure that it can be used safely at this design speed. This includes ensuring curves aren’t so sharp that vehicles slide off the road, and that drivers can see far enough ahead to stop safely in an emergency. This means any vehicles that go faster than the design speed are at a higher risk of collision.Many argue that these design parameters are based on historical designs and that modern vehicles have more effective brakes and handling. If this is true, it would mean existing road design standards are conservative and the risks of driving faster than the design speed have been reduced. A wide-ranging review of the standards, including a look at changes to vehicle design, is to be completed by 2020 and may lead to updates in the way roads are built.But even if today’s vehicles can safely drive faster than our roads’ design speed, 95% of all road crashes have human error as a factor. Most of us are simply not the good drivers we think we are. The recent launch of a national campaign highlighting the failure of drivers on England’s roads to keep a safe distance illustrates this point only too well. Higher speeds gives us less time to respond and react to a critical situation. As such, it’s perhaps unsurprising that a recent OECD study across ten countries has found that increasing road speed, including on motorways, consistently leads to a disproportionate increase in the number and severity of crashes. And more crashes leads to more congestion and longer journey times.Best case scenarioBut putting all this aside and assuming you were able to continuously drive safely on the motorway at the speed limit, how much time would a 10mph increase typically save you? Despite carrying large volumes of traffic in a relatively safe manner when compared with other routes, motorways comprise just a small proportion of the UK road network. The start and end of any trip tend to be on local roads in urban areas, inevitably forming the slowest part of any journey, and this would not benefit from the change in the speed limit.Government statistics show that 88% of trips on motorways are less than 50 miles in length. Assuming it were possible to drive continuously at 80mph instead of 70mph, the time saving on such a journey would be only five minutes at the very most.So all things considered, on a good day, increasing the motorway speed limit would save the majority of motorists just enough time to make a cup of tea. Whether drinking tea will boost national productivity is a matter for an entirely separate debate. But, aside from the question of whether being able to get to meetings faster would really impact national productivity, would raising the motorway speed limit even make that much of a different to journey times?The main problem with this idea is that persistent congestion often prevents people from travelling at the existing speed limit. A former chief executive of the Highways Agency suggested we should even expect peak time motorway speeds as low as 40mph on some routes. Another problem is phantom traffic jams, which usually occur when drivers are travelling too fast in comparison to the traffic around them. If one driver rapidly brakes, the driver behind them will have to do the same and so on until a whole line of traffic is forced to stop. The way the UK has primarily tried to tackle the issue of congestion in recent years is not by building more roads but by introducing so-called smart motorways. These use electronic signs to change the speed limit depending on the flow of traffic. Ironically, by keeping drivers travelling slower, smart motorways can help prevent phantom traffic jams and ensure everyone gets to their destination faster. This technology can also be used to allow even higher speeds when there are fewer cars on a road. In the Netherlands, smart motorways have been introduced in combination with an increase in the motorway speed limit from 120km/h (75mph) to 130km/h (81mph). But drivers travelling during peak times tend not to benefit from the higher limit because congestion causes the smart motorway to reduce the speeds, so any potential productivity boost is limited.

The UK should raise its motorway speed limit for cars and vans to 80mph as a way of increasing national productivity, a government minister recently suggested. It’s a perennial political idea that has already been proposed and then ruled out by the government at least once in the past decade. Despite claims that the current 70mph limit is embedded in the national psyche, 48% of car drivers choose not to comply with it.

Clinical information and genetic data contained within electronic health records (EHRs) represents a major source of useful information for biomedical research but accessing it in a useful way can be difficult. Writing in the International Journal of Intelligent Engineering Informatics, Hassan Mahmoud and Enas Abbas of Benha University and Ibrahim Fathy Ain Shams University, in Egypt, discuss the need for innovative and effective methods for representing this huge amount of data. They point out that there are data mining techniques as well as ontology-based techniques that can play a major role in detecting syndromes in patients efficiently and accurately. A syndrome is defined as a set of concomitant medical symptoms and indicators associated with a given disease or disorder.The team has reviewed the state of the art and also focused on reviewing the well-known data mining techniques such as decision trees (J48), Naïve Bayes, multi-layer perceptron (MLP), and random forest (RF) techniques and compared how well they each perform in the classification of a particular syndrome, heart disease.The team concludes that in experiments with a public data set, the RF classifier provides the best performance in terms of accuracy. In the future, they suggest that data mining will benefit healthcare and medicine significant for building a system able to detect a specific syndrome.

Our future depends on a transition away from fossil fuels. To map out a path, we need to get to grips with how, and why, the use of coal, gas and oil has risen to unsustainable levels. Most fossil fuels are consumed not by individuals, but by and through large technological systems, such as electricity networks, urban transport systems, built environments, and industrial and agricultural systems. While the media offers plenty of advice on how individuals can cut consumption, how to transform or supersede these technological systems is much less obvious.These unsustainable systems are deeply embedded in day-to-day life. For example, fossil-fuel-driven power stations on average use roughly three units of energy to produce one unit as electricity, while further energy is lost in transmission networks. Steel and cement are also produced in energy-inefficient ways, and used to construct heat-hungry buildings. To engineers, these are all huge opportunities for energy conservation.Car-based urban transport systems could hardly be more fuel-inefficient. That is why Atlanta in the US, a spread-out city dominated by suburban housing and car transport (including many SUVs), has 11 times the greenhouse gas emissions per head of Barcelona, Spain, which has a similar number of people, with similar income levels, but is more compact, with better public transport and a relatively car-free centre.The best way to interpret the growth in fuel consumption is by starting with the evolution of these technological systems, and the way they are embedded in social and economic systems. As I argued in my recent book Burning Up: A Global History of Fossil Fuel Consumption, such an approach can help us through a dizzying array of statistics, which themselves reflect a range of political views of consumption. Here is a guide to the most often-used ones: Provided by The Conversation Citation: Why it’s so hard to trace the patterns of unsustainable fossil fuel use (2019, March 27) retrieved 17 July 2019 from https://phys.org/news/2019-03-hard-patterns-unsustainable-fossil-fuel.html What about big corporations?Attributing emissions to fuel-producing companies helps to highlight the role of corporations. The Climate Accountability Institute’s brilliant research shows that nearly two thirds of carbon dioxide emitted since the 1750s can be traced to the outputs of the 90 largest fossil fuel and cement producers.Some headlines proclaim that these corporations are therefore “responsible” for climate change. But that’s only half the story. They produce fuel, others consume it. A list of the companies that do so – electricity producers, metals and engineering consortia, car makers, construction companies, petrochemicals and agriculture giants – would be longer and more complex, because fossil fuel use is so integral to all types of economic activity.So we need sector-by-sector breakdowns, and the International Energy Agency (IEA) publishes those. Flow charts can help visualise things, and materials flow researchers, such as the authors of Sustainable Materials With Both Eyes Open, do those. Then the numbers need interpreting; the bulky Global Energy Assessment had a shot at that.Companies and governments may be hiding things of course. There are tell-tale signs in IEA statistics: more than three times the amount of fuel used for global aviation is used on “other energy industry own use and losses” – that is, fuel the energy companies have either lost, or lost track of. And IEA reports on energy efficiency, which rely on companies to detail improvements, are full of complaints that crucial information is withheld.Military use is largely hidden. The US Department of Defense was in the 2000s the world’s biggest single consumer of commercial energy, wolfing down more than Nigeria. And at least we have that information: many countries simply don’t report military fuel use.Tracing fossil fuel use is not simple. The focus needs to shift from individual consumption to the big technological systems by and through which most fossil fuels are used, and the social and economic factors that make them work the way they do. A harsh light needs to shine on companies that consume the fuels, as well as the producers. Consumption-per-head statistics measure a country’s total energy use, and divide it by the number of people in the country. Developing nations use these figures at international climate talks, to underline the historic inequality of consumption. For example, in 2014 the US consumed 31 times more energy products per head than Bangladesh; three decades earlier in 1984, it was 71 times more. But no US citizen consumes those quantities of energy products directly. His or her share is mostly swallowed by the technological systems. Even those car drivers in Atlanta do not control their own consumption: it’s difficult to live there without a car, except in hardship.These numbers also hide inequality within nations, such as between an extravagant SUV driver and an unemployed cyclist. The prominent economist Thomas Piketty and his colleague Lucas Chancel tried to correct for that anomaly. Using wealth statistics, they estimated individuals’ fuel use, from the super-rich to the poorest, and found even more eye-watering contrasts. But such approaches still do not account for the technological systems that consume most fuels.Including ‘outsourced’ emissionsConsumption-based emissions statistics filter out the effect of one aspect of international inequality. They count greenhouse gases emitted in manufacture according to the countries where products are used, instead of where they are made. So emissions “embedded” in a steel bar, produced in a carbon dioxide-belching coal-fired furnace in China and exported to the US, are counted as American. These numbers underline that, even today, the vast bulk of fossil fuel use is in, or for, the global north.

27 Oddest Medical Case Reports 10 Medical Conditions That Sound Fake but Are Actually Real 10 Strangest Medical Cases of 2018 A man in Gaza with an extremely rare skin condition dubbed “tree man syndrome” says his life has been changed by a pioneering surgical treatment, according to news reports. The man, 44-year-old Mahmoud Taluli, has undergone four surgeries in the last two years to remove extensive, wood-like lesions on his hands, according to NPR. Prior to the surgeries, Taluli hadn’t been able to use his hands for more than a decade. “After years of suffering and solitude, I can finally live a normal life,” Taluli told NPR. “I can play with my children. I can go to family events. I no longer need to cover my hands when I go out in public.”Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65907-tree-man-gaza-surgery.html?jwsource=cl已复制直播00:0000:3500:35 Taluli has a rare genetic condition called epidermodysplasia verruciformis, which makes him much more susceptible to skin infections caused by the human papillomavirus (HPV), compared with the average person, according to a 2010 report of the condition published in the journal Disease Markers. People with this condition have immune system problems that prevent them from properly fighting off HPVs — a group of more than 150 related viruses. In healthy people, HPVs often don’t cause symptoms, but in people with epidermodysplasia verruciformis, the infections lead to the formation of wart-like skin lesions, which progress to malignant tumors in about 50% of patients, according to the 2010 report. There is no cure or standard treatment for the condition. Taluli’s treatment has involved doctors making deep incisions into the skin to remove thousands of lesions, NPR reported. This tissue removal often requires skin grafts from other parts of his body to help with healing. The treatment has allowed Taluli to use his hands again, but it is not a cure — new growths continue to show up, and Taluli will need a fifth operation this summer to remove these new lesions, as well as some scar tissue, NPR reported. Still, the treatment has been largely successful in improving Taluli’s hand function. “We didn’t know if there would be anything viable left of his hands, but thank God it’s working,” Dr. Michael Chernofsky, a hand and microvascular surgeon at Hadassah Medical Center in Jerusalem, who treated Taluli, told NPR. Ultimately, doctors hope to develop a treatment that can help Taluli’s immune system better fight HPV, NPR reported. Another man with epidermodysplasia verruciformis hasn’t fared as well. Last month, it was reported that Abul Bajandar of Bangladesh had asked doctors to amputate his hands due to pain from the condition, according to Fox News. Although Bajandar has had more than 20 surgeries to remove skin lesions, the growths appear to be coming back worse than before. Chernofsky told NPR that amputation is usually not a good idea, because the patient would likely still experience pain from severed nerves.

About 80% of all the matter in the cosmos is of a form completely unknown to current physics. We call it dark matter, because as best we can tell it’s…dark. Experiments around the world are attempting to capture a stray dark matter particle in hopes of understanding it, but so far they have turned up empty. Recently, a team of theorists has proposed a new way to hunt for dark matter using weird “particles” called magnons, a name I did not just make up. These tiny ripples could lure even a fleeting, lightweight dark matter particle out of hiding, those theorists say. [The 11 Biggest Unanswered Questions About Dark Matter] The dark matter puzzle We know all sorts of things about dark matter, with the notable exception of what it is.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65887-quasiparticles-could-unmask-dark-matter.html?jwsource=cl已复制直播00:0000:3500:35 Even though we can’t directly detect it, we see the evidence of dark matter as soon as we open up our telescopes to the wider universe. The first revelation, way back in the 1930s, came through observations of galaxy clusters, some of the largest structures in the universe. The galaxies that inhabited them were simply moving too quickly to be held together as a cluster. That’s because the collective mass of the galaxies gives the gravitational glue that keeps the cluster together — the greater the mass, the stronger that glue. A super-strong glue can hold together even the fastest moving galaxies. Any faster and the cluster would simply rip itself apart. But there the clusters were, existing, with galaxies buzzing around within them far faster than they should given the mass of the cluster. Something had enough gravitational grip to hold the clusters together, but that something was not emitting or interacting with light. This mystery persisted unresolved through the decades, and in the 1970s astronomer Vera Rubin upped the ante in a big way through observations of stars within galaxies. Once again, things were moving too fast: Given their observed mass, the galaxies in our universe should’ve spun themselves apart billions of years ago. Something was holding them together. Something unseen. [11 Fascinating Facts About Our Milky Way Galaxy] The story repeats all across the cosmos, both in time and space. From the earliest light from the Big Bang to the largest structures in the universe, something funky is out there. Searching in the dark So dark matter is very much there — we just can’t find any other viable hypothesis to explain the tsunami of data in support of its existence. But what is it? Our best guess is that dark matter is some kind of new, exotic particle, hitherto unknown to physics. In this picture, dark matter floods every galaxy. In fact, the visible portion of a galaxy, as seen through stars and clouds of gas and dust, is just a tiny lighthouse set against a much larger, darker shore. Each galaxy sits within a large “halo” made up of zillions upon zillions of dark matter particles. These dark matter particles are streaming through your room right now. They’re streaming through you. A never-ending rain shower o’ tiny, invisible dark matter particles. But you simply don’t notice them. They don’t interact with light or with charged particles. You are made of charged particles and you are very friendly with light; you are invisible to dark matter and dark matter is invisible to you. The only way we “see” dark matter is through the gravitational force; gravity notices every form of matter and energy in the universe, dark or not, so at the largest scales, we observe the influence of the combined mass of all these countless particles. But here in your room? Nothing. Unless, we hope, there’s some other way that dark matter interacts with us normal matter. It’s possible that the dark matter particle, whatever the heck it is, also feels the weak nuclear force — which is responsible for radioactive decay — opening up a new window into this hidden realm. Imagine building a giant detector, just a big mass of whatever element you have handy. Dark matter particles stream through it, almost all of them completely harmlessly. But sometimes, with a rarity depending on the particular model of dark matter, the passing particle interacts with one of the atomic nuclei of the elements in the detector via the weak nuclear force, knocking it out of place and making the entire mass of the detector quiver. Enter the magnon This experimental setup works only if the dark matter particle is relatively heavy, giving it enough oomph to knock out a nucleus in one of those rare interactions. But so far, none of the dark matter detectors around the globe have seen any trace of an interaction, even after years and years of searching. As the experiments have ground along, the allowable properties of dark matter have slowly been ruled out. This isn’t necessarily a bad thing; we simply don’t know what dark matter is made of, so the more we know about what it isn’t, the clearer the picture of what it could be. But the lack of results can be a little bit worrying. The heaviest candidates for dark matter are getting ruled out, and if the mysterious particle is too light, it will never be seen in the detectors as they’re set up right now. That is, unless there’s another way that dark matter can talk to regular matter. In a recent article published in the preprint online journal arXiv, physicists detail a proposed experimental setup that could spot a dark matter particle in the act of changing the spin of electrons (if, in fact, dark matter can do that). In this setup, dark matter can potentially be detected, even if the suspect particle is very light. It can do this by creating so-called magnons in the material. Pretend you have a chunk of material at a temperature of absolute zero. All the spins — like tiny little bar magnets — of all the electrons in that matter will point in the same direction. As you slowly raise the temperature, some of the electrons will start to wake up, wiggle around and randomly point their spins in the opposite direction. The higher you raise the temperature, the more electrons wind up flipped — and each of those flips reduces the magnetic strength by just a little bit. Each of those flipped spins also causes a little ripple in the energy of the material, and those wiggles can be viewed as a quasiparticle, not a true particle, but something you can describe with math in that way. These quasiparticles are known as “magnons,” probably because they’re like tiny, cute little magnets. So if you start off with a really cold material, and enough dark matter particles strike the material and flip some spins around, you’ll observe magnons. Because of the sensitivity of the experiment and the nature of the interactions, this setup can detect a lightweight dark matter particle. That is, if it exists.

11 Fascinating Facts About Our Milky Way Galaxy Can a chameleon build a galaxy? According to new computer models, yes. This isn’t a surrealist joke but rather the implication of recent simulations that aim to explain the inner workings of dark energy, a mysterious force that is driving apart everything in the universe. The findings, published July 8 in the journal Nature Astronomy, lend support to a model of dark energy known as Chameleon Theory. Hints of dark energy were first discovered in the late 1990s, when cosmologists measured the light from distant supernovas and realized that the stars were dimmer than expected, suggesting that the fabric of spacetime was not only expanding, but accelerating in its expansion. Physicists proposed the existence of a force that worked in opposition to gravity, pushing things away from one another, rather than pulling them together.

The problem is that leading physics theories predict that the value of the vacuum’s energy should be 120 orders of magnitude higher than what cosmologists observe from actual measurements of dark energy in the universe, said Li. So physicists have sought out alternate explanations, including Chameleon Theory. The theory proposes a new force, atop the four already known, mediated by a particle called the chameleon particle, according to an explainer in Sky and Telescope magazine. The chameleon force would act like dark energy, driving apart galaxies in the cosmos. But having an unexpected fifth force comes with its own dilemma — how come our instruments have never before seen such a particle? The theory suggests that chameleon particles, like their reptilian namesakes, can blend into their surroundings to evade detection. Rather than changing color, these particles change mass. In high-density environments, such as that near Earth, they have a high mass and are therefore difficult to detect. This is why we don’t see the effects of chameleon particles on our solar system, but rather only on extremely large cosmological scales, where, overall, matter is sparse, according to the theory. In order to test Chameleon Theory, researchers have run powerful computer simulations, spinning virtual dark matter — an as-yet-unknown substance vastly outweighing visible matter in the universe — with the four known forces plus chameleon particles to create celestial structures like our solar system, according to a statement. But until now, processing-power limitations have meant that the models could not include ordinary, visible matter, like protons and electrons. Li and his colleagues used supercomputers to finally include the ordinary particles alongside everything else and produce galaxy-scale structures. “The simulations show that realistic galaxies, like our own Milky Way, can form despite the complicated behavior of gravity in [Chameleon Theory],” Li said. The team hopes further modeling will reveal ways to distinguished the theory from other hypotheses about dark energy, he added. So do these ideas challenge Einstein’s theory of general relativity, as has been widely reported? “Challenge is a strong word,” Jeremy Sakstein, a physicist at the University of Pennsylvania in Philadelphia who was not involved in the work, told Live Science. To test general relativity, it’s useful to have competing theories, he added, and this new research represents a step toward making predictions about what these alternatives might see on cosmological scales. 8 Ways You Can See Einstein’s Theory of Relativity in Real Life The 11 Biggest Unanswered Questions About Dark Matter Originally published on Live Science.by Taboolaby TaboolaSponsored LinksSponsored LinksPromoted LinksPromoted LinksYou May LikeVikings: Free Online GamePlay this for 1 min and see why everyone is addicted!Vikings: Free Online GameUndoTruthFinder People Search SubscriptionOne Thing All Liars Have in Common, Brace YourselfTruthFinder People Search SubscriptionUndoGundry MD Total Restore SupplementU.S. Cardiologist: It’s Like a Pressure Wash for Your InsidesGundry MD Total Restore SupplementUndoArticles VallyDad Cuts Daughter’s Hair Off For Getting Birthday Highlights, Then Mom Does The UnthinkableArticles VallyUndoKelley Blue Book2019 Lexus Vehicles Worth Buying for Their Resale ValueKelley Blue BookUndoCNETMeet the US Navy’s new $13 billion aircraftCNETUndo
Shipwrecks Gallery: Secrets of the Deep Disasters at Sea: 6 Deadliest Shipwrecks More than 100 World War II-era shipwrecks decorate the seafloor around Indonesia, Malaysia and Singapore — and now, there are two fewer. According to Dutch media reports, a pair of submarines that sank off the coast of Malaysia in 1941 mysteriously vanished late last week, leaving behind only some broken scraps and ghostly outlines in the sand. The wrecked subs — Dutch vessels named HNLMS O 16 and HNLMS K XVII — also contained the remains of 79 crewmen, which are now missing. [17 Mysterious Shipwrecks You Can See on Google Earth] How does a shipwreck simply disappear? According to Dutch government officials, the subs were likely stolen by scrap-metal scavengers, who have made a habit of pilfering old wrecks from the region. As many as 40 World War II-era ships have been partially or completely dismantled by scavengers, a 2017 report by the Guardian found, resulting in the desecration of the remains of some 4,500 crewmen who went down with their ships.Headbutting Tiny Worms Are Really, Really LoudThis rapid strike produces a loud ‘pop’ comparable to those made by snapping shrimps, one of the most intense biological sounds measured at sea.Your Recommended PlaylistVolume 0%Press shift question mark to access a list of keyboard shortcutsKeyboard Shortcutsplay/pauseincrease volumedecrease volumeseek forwardsseek backwardstoggle captionstoggle fullscreenmute/unmuteseek to %SPACE↑↓→←cfm0-9接下来播放Why Is It ‘Snowing’ Salt in the Dead Sea?01:53 facebook twitter 发邮件 reddit 链接https://www.livescience.com/65894-dutch-wwii-era-submarines-vanished.html?jwsource=cl已复制直播00:0000:3500:35 Salvaging a shipwreck usually requires blowing the vessel apart with explosives, then spending days or weeks hauling any valuable metals up onto the surface with a crane. For their trouble, scavengers can come away with millions of dollars’ worth of steel per ransacked ship, plus other spoils, such as copper cables and phosphor bronze propellers, according to the Guardian article. Wartime shipwrecks are protected under international treaties as the unmarked graves of departed soldiers — however, that has not stopped salvagers from destroying the wrecks of the American, British, Dutch, English, Australian and Japanese vessels resting in South East Asian waters. In March 2018, Malaysian officials signed an agreement with the Dutch foreign minister to better protect Dutch war wrecks in Malaysia’s waters. (Parts of Malaysia were once under Dutch colonial rule.) The agreement followed a string of particularly serious shipwreck desecrations; in 2016, the wrecks of three Dutch warships vanished from the bottom of the Java Sea off the coast of Indonesia, along with the remains of 2,200 people, the Guardian reported.

state politics Published on Rajasthan Pradesh Congress President Sachin Pilot – PTI COMMENT SHARE SHARE EMAIL Rajasthan December 25, 2018 Having announced loan wavier for farmers, the Rajasthan government will soon roll out some other measures to enhance the ecosystem for the farming community and for the youth in need of jobs, Deputy Chief Minister Sachin Pilot said.He said farmers’ issues and job creation for youngsters will dominate the agenda of the new Congress government in the state.Pilot, after the formation of the Rajasthan Cabinet, said work has begun and the government will start delivering on the promises made in the party’s election manifesto.“We have started working from the very first day by announcing farm loan waiver. Agrarian crisis is on the top of the agenda and very soon, there will be quick and substantive steps by the government to enhance the ecosystem for farming community to make sure that farming becomes a profitable venture,” Pilot told PTI.“We will very soon start job creation on priority basis. These are the two issues which we will be going to be principally focused on because Rajasthan deserves a government that delivers on these two fronts,” he said.The deputy chief minister said the manifesto will be given to the chief secretary, like previous times, and it will be made an official document for the government to function.“The policy promises the Congress party has made will become a firm official commitment as we move forward,” he said. The loan waiver for farmers was announced by Chief Minister Ashok Gehlot on December 19, two days after taking oath. According to a government order, farmers’ entire short-term crop loan from cooperative banks and agriculture loans up to Rs two lakh from nationalised and other banks have been waived, putting a burden of Rs 18,000 crore on the exchequer. Asked about the availability of the financial resources to bear the burden, Pilot said the government was “capable” to face the challenge. “Resource management is not a big deal if there is a political will. The previous UPA government had waived 72,000 crore of farmers’ loan and we can also do it. So, I believe, the government is fully capable and equipped to deal with any challenge,” he said. Pilot, who is also the president of the party’s state unit, said the announcement of loan waiver has not only helped farmers but also gave a message to them that the new government is ready to listen and redress their grievances. Similarly for job creation, Pilot said, the work will begin and a system for continuous job creation and recruitment will be made. “We have shown our commitment. The first decision was of loan waiver, which will be followed by other measures. Farmers and youths were never the priorities of the previous BJP government,” he claimed. Talking about the cabinet expansion held on Monday, Pilot said it was a balance between youths and experienced leaders and was an “energetic” cabinet. “Ours is a forward looking, fully charged energetic cabinet in Rajasthan and the government is fully equipped to deal with the challenges and meet the expectations of people,” he added.
