first_imgLast month, Tedeschi Trucks Band found the time to sit down with NPR’s World Cafe during soundcheck at the Keswick Theatre in Glenside, Pennsylvania. Recordings of their two-night residency are featured on in the 52- minute stream, including “Anyhow,” “Let Me Get By,” “I Want More,” “Within You Without You / Just As Strange,” as well as some discussion on what it’s like for the power couple to have full control in the studio, having just produced and released Let Me Get By.Ultimately, it’s about the band. It’s about the adventurous risks that each member of the 12-piece outfit was able to take in the studio with uninterrupted opinions and flow. You’ll also hear a little from Derek Trucks about the final days of The Allman Brothers Band, the time he’s dedicated to his family, and about what it was like having their bassist Tim Lefebvre secretly record with David Bowie on his final album Blackstar, while also on the road and recording with TTB.Listen to the full session via NPR:last_img read more


first_imgMost galaxies, including the Milky Way, have a supermassive black hole at their center weighing millions to billions of suns. But how do those black holes grow so hefty? Some theories suggest they were born large. Others claim they grew larger over time through black hole mergers, or by consuming huge amounts of gas.New research by astronomers at the University of Utah and the Harvard-Smithsonian Center for Astrophysics (CfA) shows that supermassive black holes can grow big by ripping apart double-star systems and swallowing one of the stars.“Black holes are very efficient eating machines,” said Scott Kenyon of the CfA. “They can double their mass in less than a billion years. That may seem long by human standards, but over the history of the galaxy it’s pretty fast.”“I believe this has got to be the dominant method for growing supermassive black holes,” added lead author Benjamin Bromley of the University of Utah.The study was published in the April 2 online edition of the Astrophysical Journal Letters.Their work follows up on the 2005 discovery, by a team of CfA astronomers led by Warren Brown, of hypervelocity stars — stars that were flung out of the galactic center by gravitational forces and are traveling fast enough to escape the Milky Way.Hypervelocity stars originate from a binary star system that wanders too close to the Milky Way’s central black hole. Tidal forces capture one star and eject the other. The star that is captured into orbit around the black hole later becomes fodder for the galactic monster.“We put the numbers together for observed hypervelocity stars and other evidence, and found that the rate of binary encounters [with our galaxy’s supermassive black hole] would mean most of the mass of the galaxy’s black hole came from binary stars,” Bromley says. “We estimated these interactions for supermassive black holes in other galaxies and found that they too can grow to billions of solar masses in this way.”As many as half of all stars are in binary pairs, so they are plentiful in the Milky Way and other galaxies.The new study looked at each step in the process of a supermassive black hole eating binary stars, and calculated what would be required for the process to match observations. Their simulations accurately predicted the rate at which hypervelocity stars are produced (one every 1,000 to 100,000 years). The theory also fit the rate of “tidal disruption events” observed in other galaxies, which happen when stars are shredded and pulled into supermassive black holes.Their theory shows that the Milky Way’s supermassive black hole has doubled to quadrupled in mass during the past 5 billion to 10 billion years by eating stars.“When we look at observations of how stars are accumulating in our galactic center, it’s clear that much of the mass of the black hole likely came from binary stars that were torn apart,” said Bromley.last_img read more


first_imgConsuming greater amounts of unsaturated fats is associated with lower mortality, according to a study from Harvard T.H. Chan School of Public Health. In a large study population followed for more than three decades, researchers found that greater consumption of saturated and trans fats was linked with higher mortality rates than consuming the same number of calories from carbohydrates. Most importantly, replacing saturated fats with unsaturated fats conferred substantial health benefits. This study provides further support for the 2015-2020 Dietary Guidelines for Americans that emphasize the types of fat rather than total amount of fat in the diet.The study is the most detailed and powerful examination to date of how dietary fats impact health. It suggests that replacing saturated fats like butter, lard, and fat from red meat with unsaturated fats from plants — such as olive, canola, and soybean oils — can confer substantial health benefits and should continue to be a key message in dietary recommendations.The study will be published online today in JAMA Internal Medicine.“Our study shows the importance of eliminating trans fat and replacing saturated fat with unsaturated fats,” said senior author Professor Frank Hu. Stephanie Mitchell/Harvard Staff Photographer“There has been widespread confusion in the biomedical community and the general public in the last couple of years about the health effects of specific types of fat in the diet,” said Dong Wang, S.D. ’16, a research fellow in the Department of Nutrition at Harvard Chan School and the study’s lead author. “This study documents important benefits of unsaturated fats, especially when they replace saturated and trans fats.”The study included 126,233 participants from two large, long-term studies — the Nurses’ Health Study and the Health Professionals Follow-Up Study — who answered survey questions every two to four years about their diet, lifestyle, and health for up to 32 years. During the follow-up, 33,304 deaths were documented. Researchers from Harvard Chan School and Brigham and Women’s Hospital examined the relationship between the types of fats in the participants’ diets and overall deaths among the group during the study period, as well as deaths due to cardiovascular disease (CVD), cancer, neurodegenerative disease, and respiratory disease. Different types of dietary fat had different associations with mortality, the researchers found. Trans fats — on their way to being largely phased out of food — had the most significant adverse impact on health. Every 2 percent higher intake of trans fat was associated with a 16 percent higher chance of premature death during the study period. Greater consumption of saturated fats was also linked with greater mortality risk. When compared with the same number of calories from carbohydrates, every 5 percent increase in saturated fat intake was associated with an 8 percent higher risk of overall mortality.Conversely, intake of high amounts of unsaturated fats, both polyunsaturated and monounsaturated, was associated with between 11 percent and 19 percent lower overall mortality compared with intake of the same number of calories from carbohydrates. Among the polyunsaturated fats, both omega-6, found in most plant oils, and omega-3 fatty acids, found in fish and soy and canola oils, were associated with lower risk of premature death.The types of fat that replaced other types of fat had specific health effects, the researchers found. For example, people who replaced saturated fats with unsaturated fats, especially polyunsaturated fats, had significantly lower risk of death overall during the study period, as well as lower risk of death from CVD, cancer, neurodegenerative disease, and respiratory disease, compared with those who maintained high intakes of saturated fats. The findings for cardiovascular disease are consistent with many earlier studies showing reduced total and LDL (“bad”) cholesterol when unsaturated fats replace trans or saturated fats.People who replaced saturated fats with carbohydrates had only a slightly lower mortality risk. In addition, replacing total fat with carbohydrates was associated with modestly higher mortality. This was not surprising, the authors said, because carbohydrates in the American diet tend to be primarily refined starch and sugar, which have a similar influence on mortality risk as saturated fats.“Our study shows the importance of eliminating trans fat and replacing saturated fat with unsaturated fats, including both omega-6 and omega-3 polyunsaturated fatty acids. In practice, this can be achieved by replacing animal fats with a variety of liquid vegetable oils,” said senior author Frank Hu, professor of nutrition and epidemiology at Harvard Chan School and professor of medicine at Harvard Medical School.Other Harvard Chan School researchers involved in the study included Yanping Li, Stephanie Chiuve, Meir Stampfer, JoAnn Manson, Eric Rimm, and Walter Willett.The study was supported by research grants from the National Institutes of Health.SaveSaveSaveSaveSave Related Butter’s benefits melt away Harvard researchers debunk controversial paper on saturated fat and heart health last_img read more

Pic Mark CallejaALMOST half of Brisbane home hunters would buy a studio apartment in their ideal location over the ‘Great Australian Dream’ of a quarter acre block and white picket fence.New research has found size doesn’t matter anymore when it comes to property, with nearly 42 per cent of aspiring homeowners in the Queensland capital happy to sacrifice space for location.That’s greater than the national consensus, with about a third of would-be home buyers across the country taking the same view.And Brisbane would-be buyers would be willing to pay as much as $350,000 for a studio, which only averages around 30 sqm.The Gateway Credit Union/Ipsos poll of more than 1000 respondents reveals the obsession with owning a big home with a backyard may be at a turning point — even in Brisbane.GET THE LATEST REAL ESTATE NEWS DIRECT TO YOUR INBOX HEREThe research comes as Brisbane’s long-predicted apartment oversupply is being realised, providing more opportunities for home buyers to pick up an inner-city unit for a bargain.Gateway Credit Union chief executive Paul Thomas said smaller properties offering a convenient lifestyle in suburbs close to city centres and public transport were more desirable than ever before.“Studio apartments were once considered the lowly cousin of the one-bedroom,” Mr Thomas said.“Today, however, they are a well-suited housing option for mature downsizers and younger generations that are struggling to get a foot on the property ladder.”More from newsMould, age, not enough to stop 17 bidders fighting for this home2 hours agoBuyers ‘crazy’ not to take govt freebies, says 28-yr-old investor2 hours agoThe research reflected this, with nearly 80 per cent of Brisbane respondents believing studio apartments were a good way for first home buyers to break into the market.Queensland’s fastest growing areasRare Edwardian home up for auctionSpectacular water hole a real treatWhen it comes to age, Baby Boomers are most willing to take a studio apartment in an ideal location (44.8 per cent), followed by Millennials (30.8 per cent) and then 30 to 49 year olds (27.5 per cent).Perhaps surprisingly, the majority of people surveyed in Brisbane (79.1 per cent) said they would be willing to pay as much as $350,000 for a studio apartment.It’s a trend that’s only likely to continue to grow, with the Australian Bureau of Statistics estimating that one-person households will reach 3.2 million in 2031 — more than a quarter of all households.But there is a catch with buying a studio apartment — many lenders have strict criteria when it comes to securing a home loan.“Very few lenders will consider providing a home loan for any space below 50 sqm,” Mr Thomas said.Follow Liz Tilley on Twitter @liztilley84last_img read more


first_imgNew Delhi: Coming into 2019 World Cup, England team had played a number of finals in the history of the mega event. But despite that, the Englishmen weren’t able to get their hands on the coveted trophy. However, this time around, the Brits were deemed as one of the favourites to win the championship.The same was for the reason that Eoin Morgan and Co entered the tournament as the ICC’s number-one ranked ODI team. Moreover, the fact that the Brits were playing at home, made many experts and pundits believe that England can come out trumps. The English team lost three matches in the league stages and was also in danger of getting eliminated before the semis, but the team worked regressively with the full fortitude and didn’t disappoint their fans.In the semi-final, the defeated five-time champions Australia at the Edgbaston and then upstaged New Zealand on boundary count in the final at the iconic Lord’s Cricket Ground in London. The match went down to the Super Over, which also got tied after which the number of boundaries had to be taken into account. Meanwhile, the England fans were delighted by Morgan and Co’s performance in the crunch moments.One of the fans was a popular model, named Bethany Lily April, who has a stunning 135.7 thousand followers on Twitter. She congratulated the national team on the victory at the Home of Cricket, posting three pictures where she was seen doing a strip-tease. The model captioned the three pictures and wrote, “Well done England #CricketWorldCup2019”Here’s the Tweet: Well done England #CricketWorldCup2019 pic.twitter.com/Yla9dkI1VH— Bethany lily april (@BethanyLilyA) July 14, 2019 For all the Latest Sports News News, ICC World Cup News, Download News Nation Android and iOS Mobile Apps.last_img read more


first_imgVeteran athlete Ricardo Cunningham is hoping that his own self-drive and self-belief will help him to make the best of what is left of his time on the track. He has his sights set on a successful year in either the 800 metres or 400m hurdles this year. Thirty-six-year-old Cunningham is hoping that he will be able to make one last hurrah and qualify for the 2016 Olympics in Brazil. “I have been encouraged over the years to try the 400m hurdles. My personal best over the 400m is 46.20 seconds, and the 800m has given me a lot of strength, and this event (400m hurdles) is a combination of speed and strength. It’s just for me to work on putting both speed and strength together in order to improve over the hurdles,” he told The Gleaner. The former Racers Track Club athlete, now at Cameron Blazers, finished top of the field at the recent MVP Track and Field Classic. It was his second competitive 400m hurdles, and the many-time national 800m champion clocked 50.28 seconds, the third-fastest time of the night. Ansert Whyte (49.39) of Racers Track Club and his teammate, Javarn Gallimore (50.09), finished ahead of Cunningham. Cunningham explained that the aim is to “do whatever it takes to get in the top three at trials”. Despite being in what many would consider the twilight of an athlete’s career, Cunningham is aiming to outperform his younger rivals at the National Senior Championships in June. No doubt, it will be a much sterner test than his 800m pet event where he has a personal best of 1:47.14 minutes. “It’s a new event; it’s going OK. It requires a lot of technique, but I am enjoying it thus far. The focus hasn’t been shifted from the 800m as I am still preparing for both events. They go hand in hand.”last_img read more


first_img(Visited 373 times, 1 visits today)FacebookTwitterPinterestSave分享0 In the Darwinian mindset, natural disasters are the seedbeds of creativity and progress.Most people don’t find bombs and explosions particularly useful for building functional structures. Sometimes an old structure needs to be removed by intelligently-placed explosives so that a new building can be erected on a site. Architects, though, don’t generally employ terrorists as construction workers, nor do artists create art with tornadoes. Musicians are not generally inspired by rumbling landslides for their themes.mass extinction … set the scene for the rise and age of the dinosaursCommon sense, though, gets tossed aside in evolutionary circles. Consider Science Daily‘s headline, “Volcanic eruptions triggered dawn of the dinosaurs.” By saying that widespread destruction “set the scene” for the rise of the dinosaurs, the reporter implies that natural disasters unleash the creative power of evolution:Huge pulses of volcanic activity are likely to have played a key role in triggering the end Triassic mass extinction, which set the scene for the rise and age of the dinosaurs, new Oxford University research has found.The Triassic extinction took place approximately 200 million years ago, and was proceeded by the dinosaur era. One of the largest mass extinctions of animal life on record, the casualty list includes large crocodile-like reptiles and several marine invertebrates. The event also caused huge changes in land vegetation, and while it remains a mystery why the dinosaurs survived this event, they went on to fill the vacancies left by the now extinct wildlife species, alongside early mammals and amphibians.Rebecca Morelle at the BBC News echoes the theme: “Volcanoes ‘triggered dawn of dinosaurs’.” Now while one can understand the obliteration of some inhabitants allowing other existing inhabitants to fill in the vacant niche, these articles go further, implying that the destructive power of volcanoes actually ‘triggered’ new pulses of evolutionary progress, turning early dinosaurs and mammals into bigger and better creations of natural selection. While not expressly claiming this, the news articles clearly imply it by saying that natural terror “set the stage” for dinosaur evolution, and placing the “age of dinosaurs” right after the extinction event. The BBC says,Lead author Lawrence Percival, from the Earth sciences department at Oxford University, said: “The dinosaurs were able to exploit those ecological niches that were left vacant by the extinction.”Morelle refers to a paper in PNAS, “Mercury evidence for pulsed volcanism during the end-Triassic mass extinction.” The paper asserts that mercury found in late Triassic layers corresponding to the extinction period (200 million Darwin Years ago), indicates widespread volcanism was going on. Whether volcanism is the best or only mechanism for mercury deposition, geophysicists can debate. But the paper, remarkably, says nothing about evolution, dinosaurs or mammals. The closest phrase is “subsequent biotic recovery,” which could mean a return to the status quo ante, not the beginning of a round of major evolutionary innovations.An article in The Conversation by two of the paper’s authors, though, shows them buying into the terror theory of life. Percival and his colleague Tamsin Mather at Oxford say that the volcanic catastrophe “made space for the remaining dinosaurs (and other species) to flourish.” The idea is also evident in their title, “New evidence that volcanic eruptions triggered the dawn of the dinosaurs.”The notion that destruction “set the stage” for evolutionary progress does not come from the data, but from a prior assumption that natural terror entails a creative force of some kind. Give animals a new niche via natural terror, and they will evolve upward to bigger and better forms.Cartoon by Brett Miller. Used by permission.Other Destructive Agents of Evolutionary ProgressAnother example of the mindset that terror brings good things to life can be seen in Elizabeth Howell’s headline at Astrobiology Magazine, “Sun’s UV Light Helped Spark Life.” Without doubt, ultraviolet radiation is a destructive force for life today. The high-energy rays give us sunburn and skin cancer, cause genetic mutations, and tend to disrupt useful molecules. Fortunately, our ozone layer protects us from much of the natural terror. So why consider UV a creator? The mindset is clear in her opening sentence. “High energy, ultraviolet radiation from the Sun is a known to hazard to life,” she begins, with a dramatic turn in the word yet, “yet the energy provided by our star has played an important role as the essential driver of life on Earth.” She reports on astrobiologists fully aware of the destructive potential of UV light who, nonetheless, think of it as a creative force.In this oxygen-poor, prebiotic world, solar energy may have provided the jolt to transform simple organic molecules into more complex ones, which were used as the building blocks of biology and life.Without oxygen, more UV radiation would have reached the “prebiotic soup” where molecules were trying to evolve in the evolutionary creation myth. But oxygen was likely present in some amount—and it, too, is a destructive force for molecules of biotic interest. A couple of exceptions of more complex molecules formed under lab conditions does not disprove the rule: UV and oxygen destroy what a cell would need to come together. In their mindset, though, these astrobiologists combine two destructive forces into veritable crucibles of life, much as Stanley Miller did with his spark discharges. Lightning only turns things to life in Frankenstein movies; in the real world, it kills or injures people.What other natural terrors acted as creative forces in Darwinian visions? A Mars-sized impact made possible a finely-tuned earth-moon system; the rise of oxygen created complex metabolism; erosion led to 20 new phyla in the Cambrian explosion; a comet or meteor strike created mammal diversity; ice ages enabled mammoths to emerge; antibiotics invented resistant bacteria; cosmic rays generated the genetic mutations that natural selection acted on to build endless forms most beautiful. Once intelligent design is ruled out, the only creators left are the destroyers.Even within their own belief system, there is no reason to think any one of the evolutionary bursts of innovation is connected to the preceding destructive event. Think about how the Surtsey volcano was quickly populated by extant organisms once the lava cooled. The hot lava did not create the organisms. No! Their embedded genetic instructions enabled them to “exploit” new resources made available through a colonization sequence that shows purpose and plan to fill the earth and restore the biosphere. What about hot lava could do that? Will it create more effectively if lightning strikes the lava? Maybe a meteor hitting the lava will help it “set the stage” for the “emergence” of life. Come on, people; this is stupid.Evolutionists aren’t really materialists. By employing destruction as their creator, Darwinians expose themselves as worshipers of Shiva.last_img read more


first_imgWe have shown this magnificent video before of a landing in thick fog using autoland taken from the cockpit of a Boeing 757 by Hjörleifur Jóhannesson.Many readers have asked us to put it back up on the news feed so here we go.The Category 3A approach is to Oslo Gardemoen Airport. The wind is calm with visibility of just 225 meters on the runway.Autoland systems were developed to enable aircraft to land virtually blind although they can be used in all levels of visibility.However there are limits to the amount of wind component that an autoland system can handle.For instance for a 747-400 the maximum headwind is 25 kts (28mph / 46km/hr), maximum tailwind 10 kts and a maximum crosswind of 25 kts.However for the autoland to work an airport must be equipped with an appropriate Instrument Landing System (ILS) or Microwave Landing System (MLS). There are various levels of ILS capability.CAT 1 has a decision height for the pilot of 200ft (61m) and the pilot must be able to see 2400ft (55m) down the runway. For CAT 11 the decision height is 100ft (30m) and a runway visual range of 1000ft (300m). CAT111a 100ft and 660ft, CAT111b 50ft and 246ft.Most airports have only a CAT 1 capability.The first aircraft to be certified to CAT III standards was a Sud Aviation Caravelle in December 1968 followed by the Hawker-Siddeley Trident in May 1972 to CAT IIIa. It achieved CAT IIIb  in 1975.The Trident had been certified to CAT II in February 1968.In the video listen for the heights being called out by the aircarft’s systems. The 757 enters the fog at 500ft and the first lights of the runway are seeen at just 100ft above the runway.Music on the video is by Paul Schwartz, Cantilena from the Aria 2: New Horizon album.

first_imgWritten by Christopher Plein, Ph.D. West Virginia University and MFLN Military Caregiving Team MemberChanges in Health PolicyThere is an old saying that the only thing that is constant is change. Like most adages, there is a lot of wisdom in this statement. But it provides little comfort for those who are dealing with the stresses of change. In the weeks ahead we will be exploring the concept of change – in organizations, in our professional lives, in society, and in policy and politics. Change will be the focus of a Virtual Conference hosted by the Military Families Learning Network entitled ‘Learning Through Change,’ and will be held from September 26-29, 2017. In addition, in this and my next blog, I will be discussing how change is a product of historical influences and present compromises. Understanding how change is influenced by the past and by the present can help us better encourage and manage change.In this blog, I am going to briefly talk about change in the context of politics and policy from a historical perspective. As a political scientist, I have spent much of my career examining how public policies, like Medicaid and the more recent Affordable Care Act, have been developed and implemented.Many of us are familiar with Lin-Manuel Miranda’s highly-praised hit Broadway musical, Hamilton. For many, it’s a must see – and it certainly is on my list, but I probably will have to wait for the movie to come out. As the wonderful book that the play is based on, Ron Chernow’s Hamilton (Penguin 2004), clearly shows, Alexander Hamilton was often frustrated because he could not achieve his goals of creating a more centralized government in the new United States. He ran into the fundamental reality that new laws and policies must build on existing legal and institutional foundations.In short, change is shaped by history. For example, Hamilton and the other framers of the Constitution had to take into account that states like New York and Virginia, as well as 11 others, were already well established. They could not be replaced with an entirely new system of government. As a result of constitutional decisions made some 230 years ago, we live in a federal system where not all policies mesh clearly between the states and Washington, D.C., or among the states themselves.We have explored how our federal system can create challenges for military families moving across state lines in past MFLN Military Caregiving webinars on Medicaid. This is also key to understanding current controversies surrounding the ACA and its future – some of which we have explored in previous blogs such as ‘A Little Medicaid Summer Reading’ and ‘The Affordable Care Act – What You Need to Know.’Much of the turbulence surrounding the Affordable Care Act (ACA) reflects how change is contingent on the past and moves uncertainly into the present and future. If we set politics aside, which is admittedly hard to do in today’s partisan environment, we can see that the law has been both hobbled and enabled by existing arrangements in the states, at the federal level, and in the marketplace.As radical as some have made it out to be, the ACA was developed in the context of, and depends on, existing public and private structures. Think of the ACA as a software upgrade where existing law, policy and health systems are the operating platform. We both a sense of comfort and frustration, we regularly encounter software upgrades with our favorite and most needed programs. Changes are necessary, but it would be impractical to completely replace existing systems. It is easy to apply this analogy to the policy arena. Believe it or not, the major provisions of the ACA build on statutory platforms that were first established in the 1930s and 1940s (the Social Security Act and the Public Health Service Act respectively). Existing government agencies at both the state and federal level were tasked with implementing most of the ACA.   The ACA relies on the private sector to provide insurance in the new “exchanges” which have been the subject of so much debate and controversy. Healthcare providers and systems operate much as they have done before. But like all software upgrades (especially big ones) there are bugs, problems, and unanticipated consequences.If he were alive today, Alexander Hamilton would no doubt be highly interested, perhaps a little chagrined, and no doubt impressed by the lasting legacy of the Constitution’s framers.   For example, when originally passed, the ACA all but mandated that the states expand Medicaid to new low-income populations. This was challenged by many states in the courts, with the argument being made that this did not respect state power and responsibilities in the federal system. In making its decision, the Supreme Court reached back to the time of Hamilton and ruled that the states should have more flexibility in deciding whether or not to expand Medicaid coverage. As a result, many states have expanded Medicaid – but a good number have not. Again, the past shapes change.Join me next week as we look at another force that shapes change….compromise. This MFLN-Military Caregiving concentration blog post was published on August 4, 2017.last_img read more
