MSNBC News reported that Carl Sagan’s popular 13-part series Cosmos is returning to TV this week, digitally remastered and enhanced with new up-to-date animations. The 1980 series, which began with its own Agnus Dei invocation “The cosmos is all that is, all that ever was, and all that ever will be,” went far beyond the study of stars and galaxies. It preached a profoundly atheistic, evolutionary world view of the meaning of life, its origin and destiny, and even cosmopolitics. Facing the camera in one episode, Sagan stated emphatically (after showing a case of microevolution), “Evolution is a fact, not a theory. It really happened.” Stick-figure animations made up for the fossil record by showing smooth transitions from single cell to man. Religious people, especially Christians, were routinely portrayed in a negative light – except for the Hindus, who got surprisingly good press from the science popularizer who really knew how to put the b in “billions.”Oh good. Now we can all laugh again as Sagan shows people, cities, spaceships and everything in the zoo and tells us, with all seriousness, “These are some of the things hydrogen atoms do, given fifteen billion years of cosmic evolution.” Maybe the series should be renamed Cosmics.(Visited 16 times, 1 visits today)FacebookTwitterPinterestSave分享0
Time to rewrite the textbooks again. Earth started out wet, scientists now claim, overturning decades of dogma.“Earth may have kept its own water rather than getting it from asteroids,” reads a story title in Science Magazine , a summary of a paper in Science. The authors concluded, from divination of lavas on Baffin Island collected in 1985 (Astrobiology Magazine), that the mantle must have gained its water directly from the protoplanetary nebula.Astronomers had been telling the public for many years that Earth started out dry and got its water from comets. When the deuterium ratio of comet ice turned out to be too high, they had a problem.Now, however, instead of apologizing for their mistake, they are bragging that the discovery is “exciting” and suggests that habitable planets may be much more common throughout the universe. For Science Magazine, Julia Rosen writes,In the prevailing model of an initially dry Earth, hydrating the planet seemed like “more of a one-off event,” Hallis says. However, if the planet managed to keep water from the solar nebula before it evaporated away, there’s no reason other planets couldn’t do the same thing. Hallis says that her results could mean that water-rich planets like Earth are not so rare after all.Live Science joins this chorus, claiming “the study could also have far-reaching implications for deciphering where water came from — and how it was lost over time — on other planets in the solar system, and even on planets orbiting distant stars.”The new theory messes up old beliefs, Rosen indicates, that bits of meteoric rock called carbonaceous chondrites had brought water to the Earth. It also violates tradition that the dust disk was too hot at Earth’s radius to hold any water. To get around that objection, they had to get sneaky:Traditionally, the main objection to this idea has been that the inner portion of the protosolar nebula, where Earth formed, would have been too hot for water to hang around. But Hallis’s team suggests that water floating around in the nebula snuck into our nascent planet by adsorbing to dust particles. They cite previous modeling work suggesting that this mechanism could allow a significant amount of water to survive the brutal temperatures and violent processes by which dust particles coalesced to form planets.The paper admits that temperatures in the habitable zone would have been 440 to 1340 degrees Kelvin. Those water molecules would have needed a tight grip to hang on to the dust. Maybe they “snuck” onto the back side of the grains to avoid the solar wind.The researchers merely assumed that these dust grains would clump into planetesimals and then planets. They spoke of Earth’s accretion six times in the short paper without explaining how tiny dust grains accrete, which they usually don’t. And there’s another problem keeping the traditionalists clinging to their traditions:However, some scientists aren’t ready to abandon the asteroid hypothesis just yet. That’s because, on top of bringing water, they are also believed to have delivered much of Earth’s so-called volatile elements, namely, carbon, nitrogen, and noble gases, says Conel Alexander, a cosmochemist at the Carnegie Institution for Science in Washington, D.C. To explain the abundance of these elements, there would have had to have been enough impacts to also deliver Earth’s water, he says. “That still seems to me the simplest and most attractive explanation.”Ciesla says that the new results will force scientists to re-evaluate the process of Earth’s formation. Perhaps the team’s adsorption model is correct, or perhaps water came to Earth aboard a kind of asteroid that hasn’t yet been found, or that no longer exists because it all went into making the Earth. “What we have to do is try to understand what fits and what doesn’t,” he says.The perhapsimaybecouldness index of all these articles is non-trivial. Of special note is the appeal to what “would have had to have been,” that uses the verb have three times in six words. It also seems a bit unscientific to appeal to entities that have never been found or no longer exist.They’re at least getting warmer. The Earth started out with all of its water, according to a textbook that never needs revising. (Visited 77 times, 1 visits today)FacebookTwitterPinterestSave分享0

Even when smart media entities have been proactive in approaching the new digital paradigm – the world of smartphones and tablets, social and serendipity – they have failed either through poor decision making or not putting in a full effort.The CNN DifferenceBut CNN is different. Where many newspapers and cable companies have faltered, CNN has thrived. A lot of the credit goes to the cable news company’s acquisition of Zite, the makers of a popular iPad news app. Zite is a social content discovery engine. It uses signals from sources like Twitter and Facebook to determine what a subscriber likes to read and deliver content they might not find otherwise. It began as an iPad app and was acquired by CNN in Aug. 2011.Many ZIte users cringed when they heard that CNN was taking over. The acquisition had all the hallmarks of the failed strategies that have been replayed over and over in big media since the advent of the Web: aging media behemoth thinks it can innovate by acquiring hot new media startup, then runs it into the ground.For Zite’s part, it was apprehensive about being acquired in the first place.“To be blunt, we had no desire for Zite to be acquired after what happened at Microsoft,” said Zite CEO Mark Johnson. Johnson was part of Powerset, a semantic search startup that was acquired by Microsoft in 2008. Johnson notes that out of about 60 people from Powerset that went to Microsoft, only about six of them are left at the company. So when CNN approached Zite about an acquisition last year, Johnson was wary about going in that direction. A Surprisingly Happy MarriageThe acquisition has turned out well for both parties. Instead of CNN gutting the Zite team and letting the product languish, Zite got its own office in San Francisco and has actively hired more employees. “I had very frank conversations with [KC Estenson, CNN senior vice president and general manager of digital] about what the structure would be,” Johnson said. On the flip side, Zite has provided CNN with a variety of positive elements. Estenson noted that Zite gives CNN a presence on the West Coast with the ability to “tap the mindset of San Francisco.” CNN digital has a history of thinking progressively about online news dissemination. Zite gave CNN a distinct mobile discovery engine with backend technology that could be worked into CNN’s homepage. The next phase was to make sure that Zite survived the acquisition.Estenson was very cognizant of Johnson’s concerns. “We wanted Mark and the team to have the freedom to try new things,” Estenson said. Zite Kept Growing After The AcquisitionZite has spread from an iPad-only app to a variety of platforms, including the iPhone as well as Android tablets and smartphones. The company launched branded advertising and a publisher program. Last week it launched its first integration with the parent company, called CNN Trends, powered by the Zite technology stack. CNN Trends pairs original CNN coverage with popular related stories from around the Web. “CNN is what you need to know, Zite is what you want to know,” Estenson explained. So, why has the CNN/Zite partnership worked so well?Many people thought that an old media company like CNN would not understand what Zite was doing and eventually force it to bend to the larger company’s will. That has not happened.To CNN’s benefit, it recognized that it had bought not just a popular news discovery app, but the technology behind it.Zite started as a group of researchers in Vancouver that had a product called Worio (Web Of Research, Iteration One), which provided serendipitous discovery through a search engine. Worio was built around the concept of personalized search that recognized not just what you were searching for, but the topics related to it. The approach of personalized news and content discovery is what appealed to CNN. Estenson says that topic personalization will be the future of how big media brands need to market content.CNN Kept An Open MindThe fact that Zite has survived the CNN acquisition suggests that the cable news giant kept an open mind when it approached Zite. CNN recognized that it needed some skin in the mobile game and Zite has provided that – along with key backend technology to improve CNN’s homepage.In the end, the combinattin has formed a rare success story in an arena where new media and old media typically fight for eyeballs: a mutually beneficial relationship built on trust and respect.“There is a deep respect from me and the other CNN execs for the Zite team,” Estenson said. “We are not bullshitting about how much we get along and how well we work together.” What it Takes to Build a Highly Secure FinTech … Why IoT Apps are Eating Device Interfaces Role of Mobile App Analytics In-App Engagement
You could say the villagers here look the bull in the eye. There was a time when Baghpat was notorious for its gun-toting dacoits. But the local people wanted a more honourable reputation for their district.And you can’t say they haven’t succeeded. You still hear the click of triggers being,You could say the villagers here look the bull in the eye. There was a time when Baghpat was notorious for its gun-toting dacoits. But the local people wanted a more honourable reputation for their district.And you can’t say they haven’t succeeded. You still hear the click of triggers being pulled and the loud retorts as the guns fire, particularly in Johri village. But the idea is not to frighten people into giving up their material wealth. Winning medals is.In the past three years marksmen from Johri, 50 km from Delhi, have won medals in national and international shooting tournaments. Seema Tomar won a gold and a bronze at the 1999 Kathmandu South Asian Federation (SAF) Games.Zakir Khan and Shweta Choudhary won medals at the Meeting of Shooting Hopes contest held at Plzen in the Czech Republic. Vivek Singh – gold medal winner at the Asian, Commonwealth, SAF and National Games – even got the Arjuna Award in 1999.The man behind the transformation of this tiny village is a native who works in Delhi as a physician. Rajpal Singh, 51, got hooked to shooting when he saw the sport at the 1982 Delhi Asiad. He was so captivated that he took up the sport, becoming proficient enough at it to win a few national medals.But it was Rajpal’s decision to set up a 10-m shooting range at his village that put Johri on India’s sports map. Started in the courtyard of a dilapidated haveli, the Johri Rifle Club failed to generate enthusiasm.advertisement”Initially, the villagers felt I was misleading their children who needed to work in the fields,” says Rajpal. The club started with four trainees, most of them children of Rajpal’s friends. The turnaround came when two elderly women became members.During her regular visits to the club – she escorted her granddaughter to the range every day – Prakasho Tomar, 68, developed a fascination for shooting. Encouraged by Rajpal and her own family, Tomar started practising seriously.Soon her sister-in-law Chandro, 65, joined in. Finding these grey-haired matrons training with air pistols, the villagers started sending their children to Rajpal’s classes. Today, the club’s membership has crossed 200-and Johri sends big contingents to the national championships.AGE NO BAR: Sexagenarian Prakasho Tomar trains with youngsters at the Johri Rifle ClubAll this when Rajpal’s shooters train with antiquated weapons on a primitive, thatch-roofed range. The Sports Authority of India (SAI) has provided air pistols to the club’s two international medal winners – Seema and Zakir – but most members train with donated or loaned weapons.Rahul Gandhi, son of former prime minister Rajiv Gandhi and once a Rajpal trainee, gifted an imported air pistol. So did Jayant Singh, son of Union Agriculture Minister Ajit Singh. Rajpal’s son Vivek contributed Rs 50,000 of the Rs 1.5 lakh he got as the cash component of the Arjuna Award.All these have helped. Following their good performances, a few of Rajpal’s disciples now train on SAI scholarships; five are sponsored by organisations like Air-India and Indian Airlines. Shooting has even helped Rajpal’s two sons find jobs with the Indian Airlines.Rajpal divides time between his work at Municipal Corporation of Delhi dispensaries and the shooting range in Johri. “I believe in lighting one candle with another. Now people I have trained are imparting training to others in Johri and other places,” he says. For instance, Farooq Pathan, a former trainee, now coaches at Meerut University and Kuldeep Tomar is the official coach of Delhi University.Rajpal himself has trained the national shooting teams of Nepal and Mauritius. He also helped Punjab Chief Minister Parkash Singh Badal set up a national shooting academy in Badal village in his state. Fear of political and administrative interference has prevented Rajpal from approaching the Government for funds. “I will ask for the Government’s help only after my trainees prove their mettle,” he says.SAI has not responded to his request for the adoption and upgradation of the Johri Rifle Club. But even if the club fails to get recognition, Rajpal has the consolation of knowing that his aim to improve the fortunes of youngsters in Johri through his beloved sport has hit the bull’s-eye.
Oklahoma State’s offensive line depth has suffered a big hit for 2018.Junior center Tyler Moore announced on twitter Monday afternoon that he is retiring from football because of back injuries.“This is gonna be a hard one. For those who do not know,, I had a Lumbar Microdiscectomy on both my L4 and L5 vertebrate in my back in March earlier this year. I have been through rigorous rehab since and have faced trials and tribulations that has shaken me to my foundation. This didn’t worry me, I knew exactly what I was getting into; I did this for the love of my sport and the people that I have met through it and I was okay with that. In my treatments I have had many set backs, but none as bad as this recent episode. I began to experience recurring symptoms that I had before my surgery, such as harsh pain in my back and shooting pains coming down my legs; which also includes not having sensation in my right foot since my injury. Me and my family went to see my surgeon to see exactly what was going on and discussed a potential revision surgery for my back, making a total of two back surgeries at 21 years old. It deeply saddens me to tell y’all that I am pursuing a medical retirement from my football career here at OSU. This decision was not made hastily or lightly, and was made in consideration of my future quality of life after football. I want to thank Coach Gundy and all the support staff at Oklahoma State for accepting me into their family and letting me continue my education, which otherwise might not have been possible without.”Moore is a 6-foot-4, 305-pound center from Galena Park, Texas who transferred to Minnesota back in January. He started 20 straight games at center for the Gophers before suffering the back injury that forced him to have surgery.While he never saw the field for OSU and was sitting out this season due to NCAA transfer rules, the loss is a blow to the Cowboy’s line depth in the future. Moore would have been one of the front-runners to replace senior Brad Lundblade, who will exhaust his eligibility at the end of the season.If you’re looking for the comments section, it has moved to our forum, The Chamber.

By Jorge Barrera APTN National NewsManitoba Keeewatinowi Okimakanak Grand Chief David Harper’s plan to classify sponsors for the upcoming Assembly of First Nation election event in Winnipeg by traditional clan designations has upset some chiefs in his organization.Chiefs gathered at the AFN’s annual general assembly in Halifax this week selected MKO to host the election for national chief in Winnipeg this coming December.The dismal state of MKO’s finances, however, has led MKO-member chiefs to question whether the organization had the financial ability to host such a large and important event. The organization has been warned the federal Aboriginal Affairs department could put it into co-management or third party management if it doesn’t get its books in order.Yet, despite this, Harper said during the AFN assembly MKO was “financially ready” to host the event.Harper refused requests from APTN National News for an interview.A spokesperson for MKO said the organization would be relying on the Manitoba government, Tourism Winnipeg and third-party sponsors to help pay the bills.In an effort to attract cash, MKO plans to award Bear, Eagle, Sturgeon and Wolf Clan designation to sponsors, according to a sponsorship package obtained by APTN National News. The sponsorship package was drawn up on the assumption the AFN election would be held on Sept. 30.APTN National News confirmed the sponsorship clan plan remains the same for the December event.The document shows that a sponsor who contributes $75,000 or more to the AFN election event will be classified as Bear Clan. An Eagle Clan designation will go to sponsors who contribute $50,000, a Sturgeon Clan designation will be bestowed on sponsors contributing $25,000 and the Wolf Clan goes to sponsors who put up $15,000.Bear, Eagle and Sturgeon Clan-level sponsors will get a chance to attend a private reception with the newly elected national chief, according to the document. All clan-designated sponsors will have a seat on the planning committee for the event.The use of traditional clan designation, however, has upset some MKO member chiefs.“Trying to utilize our sacred clan system for the purpose of this nature is not right. As Indigenous people, a clan system is very sacred to us and to use it as an economic development strategy is not something we should do,” said an MKO-member chief who requested anonymity. “That is not right using our sacred clan system.”Harper’s plan to sell sponsorships for a “spiritual services event” to coincide with the AFN election is also causing concern. Harper, who is a born-again Christian, has organized Gospel jamborees to coincide with MKO events and there is suspicion among some MKO chiefs that the organization’s money is used to support revival services.“There were certain things that were not budgeted for that the grand chief insisted would get funded,” said another MKO member chief. “There were certain revivals (Evangelical Christian services) that he would associate with the businesses we were doing. He has these Gospel jamboree that are usually loosely connected to events that MKO hosts and he would us MKO funds for this.”An official with MKO, who was not authorized to speak on behalf of the organization, said revival and “prayer services” are paid for by sponsorship dollars.Harper is facing increasing discontent from the MKO chiefs who voted him into the job. There is a move to oust the grand chief over allegations of financial mismanagement and suspect transactions with MKO dollars.MKO is facing major financial difficulties, according to documents obtained by APTN National News that showed the organization faced a $976, 025 accumulated deficit as of March 2013.MKO member chiefs say they have received little information about the current state of the organization’s finances. MKO.MKO is currently under a forensic investigation called for the executive council of chiefs. The results of the most recent phase of the forensic audit is expected to be tabled at MKO’s chiefs meeting next week in Norway House First Nation, Man.The forensic audit report will reveal that laptops and cell phones were tampered with before they were handed over to auditors conducting the investigation, according to a copy obtained by APTN National News.Harper is also facing allegations he tried to obstruct the forensic [email protected]@JorgeBarrera
SALT LAKE CITY — New Year’s Eve revelers in Utah could find themselves with more than a hangover as 2019 dawns. If they drink and drive, they could end up on the wrong side of the nation’s newest and lowest DUI threshold.The 0.05 per cent limit goes into effect Sunday, despite protests that it will punish responsible drinkers and hurt the state’s tourism industry by adding to the reputation that the predominantly Mormon state is unfriendly to those who drink alcohol. The state’s old limit was 0.08 per cent, the threshold in most states.For Utah lawmakers, the change is a safety measure aimed at encouraging people not to drive at all if they’ve been drinking.The change was easily approved in 2017 by the Legislature, which is mostly Mormon and mostly Republican, and signed into law by Gov. Gary Herbert, also a Republican and member of The Church of Jesus Christ of Latter-day Saints. The religion teaches its members to abstain from drinking alcohol.“The vast majority of people nationwide think that if a person has been drinking they shouldn’t be driving,” said Republican Rep. Norm Thurston, who sponsored the measure.The change means that depending on things such as food intake, a 150-pound man could be over the 0.05 limit after two beers in an hour, while a 120-pound woman could exceed it after a single drink in that time, according to figures from the National Highway Traffic Safety Administration.The National Transportation Safety Board also backs the change, and many in the hospitality industry worry that other states will follow suit. Utah was among the first to adopt the now-standard 0.08 threshold decades ago, and lawmakers in four states — Washington, Hawaii, Delaware and New York — have floated measures to lower their DUI limit in recent years. None has passed.“Other states proposing the 0.05 law, don’t just follow blindly in the footsteps of Utah,” said Jackson Shedelbower, a spokesman for the American Beverage Institute, a national restaurant group.In 2017, the group took out newspaper ads in Utah, neighbouring states and in USA Today, featuring a fake mugshot under a large headline reading, “Utah: Come for vacation, leave on probation.”It’s unfair that smaller people could violate the new threshold after just one or two drinks in quick succession, even though they’re no more impaired than someone talking on a hands-free cellphone, his group argues.NTSB member Bella Dinh-Zarr countered that fears about the law are overblown. Nearly 100 countries have a similar limit, and it hasn’t correlated with less drinking per-capita. Federally funded research indicates the standard could save some 1,500 lives a year if adopted around the U.S., she said.“The restaurant industry should support this because it keeps their customers alive and drinking,” Dinh-Zarr said.Utah’s law takes effect as the state basks in the news that the U.S. Olympic Committee chose Salt Lake City over Denver as a future bid city, most likely for the 2030 Winter Olympics. State tourism officials say they’re not concerned about the law driving away visitors.With the increased use of Uber and other ride-hailing apps, many people going out for a night on the town don’t set foot in their own cars. In Utah, DUI arrests have dropped more than 50 per cent over the past seven years despite a booming population, according to state figures.Even if the law doesn’t present a practical problem, it could scare off some visitors who see the state as rigid about liquor laws, said David Corsun, director of the Daniels College of Business’ Fritz Knoebel School of Hospitality Management. Still, it’s hard to say how big the impact might be.“If you really want to ski Utah, you’re going to ski Utah. You’re just going to figure it out,” Corsun said.Police, meanwhile, say they’re aiming to stop dangerous drivers, not target people who might have had a drink or two and could be in violation of the lowered DUI threshold.“You can’t just stop someone who left a bar because you suspect they may have used alcohol,” said Sgt. Nick Street with the Utah Highway Patrol.Still, patrons of Salt Lake City’s burgeoning bar scene do feel unfairly singled out by the change.Stopping for a whiskey after work with her sister at the upscale pub Beerhive, Maude Romney, 29, said she’ll likely only go to places she can walk to from her downtown home.“I’m paranoid about it already,” she said.A DUI charge can be expensive and have long-term effects on careers.In a booth in a corner, recent Ohio transplant Rob Wheatley, 50, said he drinks to try new craft beers, not to get drunk. He’s skeptical that the law will be a serious deterrent for binge drinkers.“I don’t know if it’s going to change anyone’s behaviour,” he said. “If they’re going to have a beer, they’re going to have a beer.”Lindsay Whitehurst, The Associated Press
