first_imgThe Search for Extraterrestrial Intelligence (SETI) may seem a different subject than origin of life (OOL), but researchers in both depend on each other’s assumptions.  The common bond is illustrated in a SETI article on Space.com today.  Devon Burr of the SETI institute wrote an article not about intelligent aliens trying to broadcast signals to us, but about Saturn’s moon Titan, where no aliens are known to exist.  Let Burr explain the connection himself:As we search for extraterrestrial life, Earth in some sense always provides our framework.  The data indicate that life does in fact exist on this planet, and it existed here sometime before about 3.5 billion years ago (give or take a couple hundred million years).  However, thanks to plate tectonics and other pesky processes, we’re missing some critical information about this early time.  This includes information about how life got started on Earth.    Titan may come to our rescue….As many astrobiologists have asserted, Titan is supposed to resemble the early Earth in deep freeze.  The “chemical evolution” taking place there may provide clues to how life supposedly arose here out of a primitive soup.  Probably, it never got very far because of the cold on Titan, where water cannot exist as a liquid.  He mentions that a few astrobiologists still hold out hope that some kind of exotic life based on methane or ethane chemistry may have evolved there.  Still, it’s a long way to amphioxus as well as from it (02/23/2006), but that should not be a problem for natural selection, given enough time.    At the end of the article, Burr states, “continued spacecraft investigation of Titan may tell use about life on Earth in the ancient past.  In the exploration for life, Titan and Earth symbolize spatial and temporal symbiosis.”    The January 2007 issue of Sky and Telescope arrived on newsstands and contains a story that could be called the flip side of Burr’s interplanetary symbiosis.  Its provocative cover story is, “Is the Earth contagious?”  Selby Cull speculates about “reverse panspermia,” the idea that microbial life on Earth could have migrated to the other planets of our solar system – including Titan.  Large meteor impacts could have lofted material into orbit that eventually found its way to Mars, Europa or other planets or moons, complete with bacterial hitchhikers.  So even if future astronauts detect life on Titan, it might have a familiar genetic signature.    Selby Cull assumes that such a meteor impact wiped out the dinosaurs, clearing ecological niches for mammals – a claim that is highly controversial (10/24/2006).  So, for presenting that as fact, among other flights of fancy, he wins Stupid Evolution Quote of the Week for his ending lines: “If one day we find fossil bacteria on another world, will genetic testing be able to distinguish a citizen of Titan from an expatriate from Earth?  Depending on what we find, we may never be able to tell whether they are truly aliens or just exiled earthlings – displaced by the very catastrophe that made human life possible.”There is a continuum of belief from big bangers to astrobiologists to chemical evolutionists to Darwinian biologists to SETI researchers.  They are all blood brothers sharing a common mythology.  A phylogenetic search of the evolution memes show that astrobiologists and SETI enthusiasts and complete wackos spring from a common ancestor.  They will believe anything, make the wildest unsupported statements, and uniformly ignore evidence for design that stares them in the face.  Their eyes and ears appear to be tuned to mystical fantasies incomprehensible to reasonable humans.  Maybe they are from another planet.(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_imgThe opportunities of the digital age could be the engine of growth for South Africa, delegates heard at the Vision 2030 Summit. It needed more investment in skills and infrastructure, but it could use technology to push local innovation.The digital age offers South Africa the opportunity to change the face of our economy. (Image: Strike a pose photography)Sulaiman PhilipInvestment in information and communications technology infrastructure today will bear fruit before the National Development Plan (NDP) ends in 2030. Embracing the opportunities of the digital age could be the engine of growth in South Africa. This was the view of speakers at the Vision 2030 Summit held in Johannesburg between 21 and 22 June.As Limpopo Premier Chupu Mathabatha pointed out in his keynote address, to work towards a possible future we need to be able to visualise it. The NDP is that vision. “The people of South Africa, united in their diversity, have all embraced this future as visualised in the NDP. The challenge for all of us is to put shoulder to the wheel and work in unity towards this shared future.”The South African contextBrand South Africa’s head of research, Dr Petrus de Kock, set the context upon which South Africa needs to build. South Africa, despite its many challenges, remains a magnet for investment. For South Africans, it still offers the best opportunity for personal development. “We talk about vision but to transform our world we need imagination.”The world, De Kock pointed out, was still recovering from the economic meltdown of 2008. In some countries, especially Western economies, that had led to more aggressive inward-looking policies. South Africa had escaped the worst and as future growth would be driven by the Asian/African axis, we could grow if we were ready.“We talk about vision but to transform our world we need imagination,” Dr de Kock speaking at the Vision 2030 Summit. (Image: Strike a Pose Photography)The country and its people remained open and welcoming he said, and pointed to our tolerance as a society. “We exist in a unique context. We are unique in our constitutional acceptance of difference, religious tolerance for example. This is the identity of who we are.”The future can be in ICTPost and Telecommunications Deputy Minister Stella Ndabeni-Abrahams — like the speakers who spoke after her — championed the benefits of the Fourth Industrial Revolution. She has been a strong advocate for the benefits that that will accrue to South Africa if we embrace the digital world.“We need to integrate digital goals into our day to day lives. We need to become comfortable with the changes and benefits that will come. Most importantly, we need to be more than just consumers of the internet.”Ndabeni-Abrahams said South Africans needed to embrace the 21st century. The digital age, she said, would allow the country to show off the innovation of which we were capable. The deputy minister acknowledged that South Africa faced infrastructure challenges, but added that innovative solutions would help to make the best use of the infrastructure we had.“We have launched the Internet for All with a pilot project in the OR Tambo municipality. The idea is that no matter where you are, you will have access. We can find solutions that have South African characteristics.”Beyond infrastructure, South Africa’s shortage of skills in digital industries had hamstrung the growth of the sector. In response to this dearth, she pointed to the public-private programme with Google, which had undertaken to train 5 million coders over five years, as the way forward.“We need to work together to breach the skills gap. We need to find these innovative ways forward, solutions that show that not only are we spending, but that we’re gaining on more digitally advanced nations.”InfrastructureOne of the important benefits of the digital age highlighted by the deputy minister would be the lower cost of communication. Working towards lowering costs while still innovating was Siemens’ history in South Africa since it started doing business in the country in 1860.Sabine Dall’Omo, Siemens South Africa chief executive, highlighted the company’s relevance in South Africa. Its operations contributed R6.8-billion to gross domestic product (GDP) and its technology lay at the heart of 31 mega projects. From the first telegraph built, the company had been “driving innovation and now driving digitisation”.A benefit of the digital age often overlooked was the way technology was making it easier and cheaper to transfer technology to developing nations. This benefit had allowed Siemens to use innovations developed in more mature economies to benefit South Africa.It did so in the automotive industry, for example: “One hundred and twenty thousand cars — or 50% — of cars produced in South Africa are built using Siemens technology.”Siemens’ Sabine Dall’omo and Dr Petrus de Kock being interviewed after their presentations. (Image: Strike a Pose Photography)eCommerceTo highlight the importance of the internet to economic growth, the Chinese TELE company Huawei monitored sales on one day — 18 June 2017. The study highlighted the power and opportunity presented by e-commerce.Huawei studied the buying habits of people on T-Mall, the Chinese online shopping service.It found:In a five-minute spell 200 tons of milk powder were bought onlineIn a seven-minute period 200 million nappies were boughtIn a 26-minute spell 10 million lipsticks were boughtThe fastest time between order and delivery was 13 minutes85% of all orders that day were made on a mobile deviceThis, in the words of Leonard Chang, Huawei’s managing director of corporate industry development and marketing, showed the power e-commerce had to create economic miracles. If South Africa was to meet the growth requirements of the NDP it needed to embrace digitisation. “Connectivity is not only a human right but an economic growth right.”Digitisation could be the engine for growth. While South Africa had among the strongest ICT policy frameworks, investment from the government and the public sector had lagged. The company’s research had shown that for every additional dollar (about R12) invested in ICT infrastructure there could be a $5 benefit to GDP growth by 2025.In the recently released Huawei 2017 Global Connectivity Index, it was reported that South Africa led Africa in terms of connectivity but lagged behind the rest of the world. “If we go at the same pace as we do today, we may never catch up with the frontrunners. At the same time, we must realise there is no shortcut in climbing the ladder of digital transformation.”The NDP was a start, but the vision was never enough, Chang warned. The country needed to move faster to close the digital divide. South Africa needed a strong action plan with achievable targets. One area that needed improvement was building ICT talent.Building skillsMymoena Ismail, the CEO of the National Electronic Media Institute of South Africa (Nemisa), believes South Africa was closing in on the Mobile Moment – when there was at least one mobile smartphone per citizen.She explained that the world was close to a new kind of future. “We are going to see a convergence of a new kind of tech, one that seamlessly merges physical, digital and biological spheres. If we do not take advantage and adapt, we will not benefit.”Her organisation focused on developing e-skill capacity in South Africa by offering training courses across the country. “We are part of the solution to ensure South Africa has the necessary skills to be leaders in the Fourth Industrial Revolution.”In his address, Mathabatha said the NDP identified a stronger and better educational system and a more equal society as the keys to unlock economic growth. “The NDP envisions a South Africa where everyone feels free yet bound to others; where everyone embraces their full potential, a country where opportunity is determined not by birth, but by ability, education and hard work.“This is a vision embraced by all South Africans. The challenge, as I have said, is about navigating the routes towards such a future.”Would you like to use this article in your publication or on your website?

first_imgPolls suggest the Liberals and Conservatives are running neck-and-neck, while the NDP and Greens are fighting for third.The NDP are launching their campaign today in London, Ont., one of the regions of the province they feel they’ll be able to hold onto seats. The Greens are in their own comfort zone of British Columbia, where Elizabeth May will launch her campaign in Victoria.At the dissolution of Parliament, the Liberals hold 177 seats, the Conservatives 95, the NDP 39, the Bloc 10 and the Greens 2. There are eight independents — including former Liberal cabinet ministers Jane Philpott and Jody Wilson-Raybould. The People’s Party of Canada has one seat and former New Democrat Erin Weir sits as a member of the Co-operative Commonwealth Federation. Five seats are vacant.Under the law, the election must be Oct. 21. Trudeau’s plan calls for him to fly immediately to British Columbia for a rally in the NDP-held riding of Vancouver-Kingsway.Haunting Trudeau on the trail will be the SNC-Lavalin scandal, given fresh life this morning after the Globe and Mail reported the RCMP’s investigation into potential obstruction of justice in the matter has been stymied by the shroud of cabinet confidence.Asked what his government is hiding, Trudeau says his office gave the largest waiver of cabinet confidences in Canadian history but added anything more.Before jumping on his own campaign plane this morning, a fired-up Conservative Leader Andrew Scheer said the story showcases his belief that Trudeau has lost the moral authority to govern.“Over the next five weeks I will be explaining the reasons why Justin Trudeau has lost that authority and our alternative plan,” he said in French.Scheer will spend Day 1 of the campaign in Quebec and Ontario. OTTAWA — Justin Trudeau has kicked off his bid for re-election after emerging from Rideau Hall to ask Gov. Gen. Julie Payette to dissolve Parliament.With that starts a 40-day campaign that will see the Liberal leader make the pitch to Canadians that he should be given a second term.He says that the election is a chance for Canadians to vote for the kind of Canada they want to live in.last_img read more

Two of the league’s worst and less-interesting teams — the DetroitPistons and Charlotte Bobcats – consummated a trade that hardly will alter the fate of their respective teams.Guard Ben Gordon, who never fit in Detroit, was shipped with a future first-round pick to the Bobcats for nomad forward Corey Maggette.“We welcome Corey Maggette to our organization in a transaction that provides us with a veteran scorer and defender in addition to increased roster flexibility moving forward,” said Joe Dumars, President of Basketball Operations. “We thank Ben Gordon for his commitment to our organization over the last three years and wish him the best in the future.”Gordon, 29, averaged 12.5 points and 2.4 assists in 26.9 minutes per game last season. He is on the books for $12.4 million in 2012-13 and has a player option worth $13.2 million for 2013-14.Maggette, 32, averaged 15.0 points and 3.9 rebounds in 27.6 minutes per game, although he appeared in less than half of Charlotte’s games because of injury. Maggette is entering the final year of a contract that will pay him $10.9 million. Detroit makes the sixth team he has played for in his career.The Bobcats actually acquired Maggette in a 3-team trade involving the Milwaukee Bucks and Sacramento Kings on the night of the 2011 NBA Draft. He didn’t last long. His merry-go-around figures to continue swinging after a brief stay in Detroit. read more

Malik Hooker talks to the media at Ohio State’s Pro Day on March 23, 2017 at the Woody Hayes Athletic Center. Credit: Screenshot Courtesy of Colin Hass-Hill | Assistant Sports DirectorAll 32 NFL teams were on hand at Ohio State’s Pro Day on Thursday at the Woody Hayes Athletic Center to watch the best athletes coach Urban Meyer’s program has to offer in the 2017 draft class.But the best athlete wasn’t even competing.Former OSU safety Malik Hooker was in the crowd of 122 NFL representatives that included seven general managers and nine head coaches. Dressed in a Michael Jordan “23” sweatshirt, Jordan brand shorts and shoes, the potential top-10 pick was talking with the NFL elites as he continues his recovery from his sports hernia and torn labrum surgeries in January.Because of his injuries, Hooker isn’t able to showcase his skills that he displayed in the 2016 season, when he broke a school record with three interceptions returned for touchdowns and recorded a total seven interceptions. Lucky enough for Hooker, his work on the gridiron doesn’t need to be supported by gaudy measurables at combines or pro days to earn consideration as a top pick.But that hasn’t stopped him from wishing he was performing for the teams who are interested in him.“Just being anxious to get back out there and show everybody that, like I said about Marshon (Lattimore), I am who I am on film,” Hooker said. “Ain’t no secrets about it. (I) feel like that’s just more so just wanting to compete again. I haven’t ran since the Clemson game in January, so just trying to get back in the mix of things.”Hooker said he has heard from nearly every NFL team, mostly discussing his injury, recovery and expected return time. For now, he said he’s ahead of schedule.The All-American safety said he has started to run in the pool and is roughly eight weeks away from being back to full-time football activities. He also posted a video on Twitter last week of him catching a ball while side-shuffling on a treadmill.pic.twitter.com/kPfDL9IGf5— Malik Hooker (@MalikHooker24) March 17, 2017“It’s more so just taking it step by step,” Hooker said. “I have to get my legs back under me and condition and stuff like that. It’s more so my body type of thing, waiting until my body feels like it’s ready to get back out there and compete.”As the process continues until the NFL draft on April 27, Hooker said his patience is being tested. Not being able to go in the NFL Combine, not participating in his pro day and having to watch his teammates perform in the pro day makes it that much more difficult for a competitor like Hooker to remain patient in his rehabilitation process.But he has found one thing to do in his spare time: sign a contract with the Jordan brand.Hooker told reporters that he signed with the brand last week, which is why he was dressed in apparel designed with the image of the NBA legend.“It’s definitely a great thing,” he said. “They don’t sign too many people. For me to be in that position to say that I signed with Jordan is definitely a blessing and a shocking thing for me.”Former Buckeye cornerback Marshon Lattimore has recently climbed draft boards, projected as high as No. 3 to the Chicago Bears by NFL.com’s Charley Casserly. If Hooker was able to run in the 40-yard dash, or perform in any of the drills, his stock might have risen as well.However, Hooker is still projected as a high first-round pick, likely in the top 10, and he said that worrying about his draft stock or where he will be selected takes away from the experience of preparing for the NFL.“There’s a lot of great DBs in this group for sure,” he said. “So for me to be rated as a top DB is definitely an unbelievable thing and a blessing.” read more
