Without water, DNA bases fall apart quickly. Any origin-of-life models expecting the building blocks of DNA (nucleotides) to stick around for long are going to suffer, say researchers from Oregon State University. The molecules can enter a “dark state” in which they are highly vulnerable to UV radiation. This idea was once considered “scientific heresy” – so much so that the researchers “had a lot of sleepless nights” defending the idea from critics:The core of the debate, [Wei] Kong [professor of chemistry] said, relates to the behavior of the nucleic acid bases – adenine, thymine, guanine and cytosine – which as A-T and G-C base pairs form DNA and ultimately become the blueprint for all living things. One of the most basic premises of biochemistry is that these nucleic acid bases are very stable, as they would have to be to prevent rampant mutations and make an organized genetic structure possible. But studies at OSU, which were done with highly sophisticated electron spectroscopy, showed that the alleged stability of the nucleic acid bases in DNA is largely a myth. (Emphasis added in all quotes.)Isolated DNA bases, in other words, do not have the stability scientists thought they did. They are extremely vulnerable to UV damage for short periods:The lifetime of the dark state is not long – a nanosecond is one billionth of a second. But it’s more than enough time for DNA mutations to happen, Kong said. And the existence of this dark state raised questions about how life ever could have begun, given that the genetic carriers were so easily mutated or destroyed during this very brief but very vulnerable time. “When the bases of DNA were first being formed billions of years ago [sic], the atmosphere was actually quite hostile,” Kong said. “It was a period prior to any protective ozone layer on Earth and the ultraviolet radiation was very strong. So if primordial DNA bases were forced into this vulnerable dark state, they should have incurred large amounts of photochemical damage that would have made the very survival of these bases difficult, let alone further evolution of life.”At this point, the press release takes a dramatically optimistic turn: the dark state disappears in the presence of water. “So if water were present, the earliest DNA bases would have been able to survive and eventually help form the basis for ever-more-complex life forms,” they claim. The findings suggest, Kong said, how water could have been an absolutely essential compound to allow early DNA bases to remain stable, resist mutation, and ultimately allow for the evolution of life….“What this is really telling us is that life is a unified process,” Kong said. “It’s not just a group of DNA bases, but it’s also the physical environment in which they exist. Later on, as life became more evolved [sic], there were other ways to achieve genetic stability. But at first, it simply may not have been possible without water.”So while the news seems bad, they were able to spin it positively by adding water: “the presence of water was the key to the evolution of life on Earth, making it possible for life to emerge [sic] from what was once a hostile and unforgiving primordial soup of chemicals and radiation” [sic]. In other words, don’t try freeze-dried primordial soup.The only good news here is that these researchers have not completely obliterated all hope. This is not good news for the OOL (origin-of-life) school. They have constrained further a hopeless situation (see online book). This “radical heresy” removes any possibility of key building blocks forming away from water. Remember when Steve Benner postulated ribose forming in a desert with boron, because it was too unstable in water? (11/05/2004) Now, the poor guy has to make the ribose in the desert (hoping that UV radiation won’t destroy it there), then get it into the water where the A, C, T, G or uracil are, hoping somehow that they will join up with phosphates on some clay mineral, and then link into polynucleotide chains that can both code for information and perform enzymatic functions (RNA World), but also find a safe haven in some membrane that is not so tight it becomes a death trap. Sounds like a hard story to sell to Congress. Things are not going too well for astrobiology these days.(Visited 8 times, 1 visits today)FacebookTwitterPinterestSave分享0
We couldn’t live without the weak force, the least understood and underappreciated natural force.David Armstrong wants to educate people about the weak force. In a press release from the College of William and Mary, Joseph McClain introduces us to the physicist who thinks people should appreciate a property of the universe without which life could not exist.Armstrong came to William & Mary in 1994. Now, as Chancellor Professor of Physics, divides his time between Small Hall and the Jefferson Lab, where he collaborates on a number of particle-physics experiments, most of which involve the weak force. When Armstrong talks about his work to people who don’t speak physics, he starts by explaining that the weak force is one of the four fundamental interactions that keep the universe running.Without the weak force, the sun and life would be impossible.“Two of them are familiar to most of us,” Armstrong said. “Gravity: it keeps the planets in orbit around the sun and keeps us affixed to the Earth. Electricity and magnetism: We’ve learned since Maxwell that they’re two aspects of the same force. We’re familiar with those, and electromagnetism is what’s responsible for the electrons staying in orbit around the nucleus. Basically, all of chemistry arises from electricity and magnetism.”Less familiar to the lay public, he said, are the two nuclear forces. The strong force holds together the protons and neutrons (and their constituent quarks) in the nucleus. The last, and least familiar, of the fundamental interactions is the weak force, responsible for certain kinds of radioactive decay.“Unlike those other interactions, I can’t give you an example of something that’s held together by the weak force,” Armstrong said. “But the weak force is incredibly important, because life wouldn’t exist without it.”How so? What has the weak force done for you lately? Well, it gives you sunlight. It also gives you medical imaging.He pointed out that the fusion process in the sun, whereby hydrogen atoms glom onto one another to become helium, is an example of the weak force in action. A critical step in that reaction chain takes place through the weak force, so in fact the weak force drives the sun’s nuclear furnace.“If the weak interaction were significantly stronger than it is, then the sun would have burned out years ago,” he said. “If the weak interaction were weaker, then the sun wouldn’t have ignited.”“Certain kinds of radioactive decay, which are often useful in things like medical imaging, take place through the weak interaction,” he explained.Physics aficionados can read more about the weak force in the article. One of the weird characteristics of the weak force, he explains, is that it violates a symmetry of nature called parity. “And, for scientists, the odd-one-out parity status of the weak force gives Armstrong and other physicists an entry point into the pursuit of new physics, beyond the Standard Model.”This implies that the “Standard Model” is not a complete account of matter and energy. So yes, young physics student, there is more to discover. The rest of us can be thankful that we have a beautiful star, the sun, giving us a remarkably constant flow of energy to the Earth.Paul wrote, “God chose what is weak in the world to shame the strong” (I Corinthians 1:27). Isn’t it just like God to amaze modern physicists with something they call “weak” that turns out to be critical for life?To be dazzled by little-known facts that make life possible, read Michael Denton’s new book Children of Light. He shares the remarkable coincidences between the sun and earth that allow for the existence of large, complex creatures like humans. It almost looks designed, doesn’t it? In a podcast on ID the Future, Denton is at a loss for words to explain how astonishing the fine-tuning in the laws of physics are for our benefit.(Visited 445 times, 1 visits today)FacebookTwitterPinterestSave分享0
IBM South Africa corporate citizenship manager Sydney Hadebe and Sci-Bono CEO David Kramer. Sci-Bono helps to stimulate children’s natural curiosity and focus it on science. A hands-on approach makes learning more interesting for youngsters.(Images: Anish Abraham) MEDIA CONTACTS • Sci-Bono Discovery Centre +27 11 639 8400 RELATED ARTICLES • Sci-Bono CEO gets French knighthood • Denel helps maths, science pupils • Fostering SA’s young scientists • Pushing the science envelope • Global award for young SA innovatorAnish Abraham The Sci-Bono Discovery Centre, South Africa’s largest science centre, is aiming to boost education in mathematics, science and technology by invoking the inherent curiosity of children, and teaching them new ideas and concepts while they play and interact with the many exhibits that it hosts. Established by the Gauteng Department of Education and the private sector in 2004, the centre seeks to address the scarce skills needs of South Africa by contributing to the effective delivery of quality maths, science and technology education in all schools in the province. According to Sci-Bono CEO David Kramer, science centres are a rather recent phenomenon, with the first one taking shape in San Francisco in 1984. Known as the Exploratorium, it is one of the four biggest centres of its kind in the world, and was set up by physicist and educator Frank Oppenheimer as a way through which ordinary citizens could keep in touch with the latest advances in technology. Oppenheimer was no stranger to advances in technology – his brother Robert was one of the developers of the world’s first nuclear weapon. Since those early days, Kramer said, there were now over 30 000 science centres and museums across the world, and that there is hardly a major city that does not have one. He pointed out that the difference between science museums and science centres was that centres were not about exhibitions that people merely looked at, but were filled with interactive exhibits, made so that visitors could engage with them and learn new things. “There are 35 science centres in South Africa, but Sci-Bono is the flagship,” he said. They range in sizes from huge warehouses to a small room.Programmes and activities Kramer said that Sci-Bono had a programme of activities and projects taking place throughout the year, and its outreach programme targets schoolchildren who are unable to travel from outlying areas into Johannesburg. Programmes include a Rocket Science Club where pupils learn to design, build and launch rockets that are capable of flying several hundred metres into the air; and a robotics programme, whose participants have even competed at international level. While working on these projects, Kramer said, the children were guided and mentored by “professionals and not teachers”.Similarly, the guides who take the children around the various exhibits are young BSc graduates with a passion for science and technology – ensuring that children learn while having fun.Helping kids to learn Sci-Bono is unique, given the relationship the centre has with the Gauteng Department of Education, in that it also had a big role to play in curriculum delivery and teacher training in the fields of maths and science. The centre also runs a supplementary tuition programme in 137 sites across the province, where schoolchildren can go to learn, with highly skilled teachers from some of the province’s leading schools being brought in on the day to teach. “Over 80% of the schools that come here are from a previously disadvantaged environment, we provide them with free admission and transport,” Kramer said, adding that while wealthier schools were asked to pay for admission fees, no cash-strapped schools would be turned away. This was possible because of funding from the provincial education department, and means that Sci-Bono is not reliant on admission fees for survival.Comprehensive career guidance Another unique point is that Sci-Bono has an attached career centre. “It is a full service career centre that provides guidance and counselling,” Kramer said, adding that it was one of the few places where students from disadvantaged backgrounds could undergo free psychometric and aptitude testing. In this way, the centre not only directed the curiosity of children into the world of maths and science, but also helped improve the flow of potential candidates studying these subjects at a tertiary level. Kramer said they expected to have 206 000 visitors to the centre over the course of the year, while also reaching out to an additional 150 000 pupils through their various outreach programmes. “We are not just a conventional science centre, but we are also the control room for maths and science in Gauteng,” he said.
Share Facebook Twitter Google + LinkedIn Pinterest If you have read my previous article, when I wrote on Brazil’s corn production and the massive export record established this year, a question might have popped into your mind. How on earth is Brazil being able to export so much corn (and soybeans) if the country is well known for its terrible logistics? And, if you are really into the agricultural markets, memories of some famous photos of dozens of trucks waiting in line on some muddy road may have emerged. Some Brazilian regions still have serious logistical problems, especially when compared to the United States. In 2018, the cost per metric ton to ship soybeans from Davenport, Iowa to Shanghai, China through the U.S. Gulf reached $88.80, according to USDA data. For Sorriso, Mato Grosso (Brazil’s top producer state), shipping soybeans to the same Chinese region, using the Brazilian port of Santos, cost $122.08 per metric ton.That difference, of course, means that farmers who grow soybeans in Sorriso, located 1,190 miles from the port of Santos, in southeastern Brazil, received less for their production. While farmers in Davenport got $9.15 per bushel, the 2018 average price received by farmers in Sorriso was $8.33.The main reason for that difference is the type of transportation used to move grains from producing regions to export ports in each country. While the United States has a well-developed transportation system based on an efficient combination of rail, barge and truck, Brazil heavily relies on trucks, for many reasons that include some choices made in the past such as government incentives to the automotive industry in the early 1950s, which contributed to pushing railroads aside. Geographical and environmental peculiarities, along with several economic crises, also played a role in putting trucks and poorly maintained roads at the center of Brazil’s transportation system.The big increase in grain production in Brazilian central and northern states over the last three decades just added more drama to an already poor infrastructure, resulting in trucks stuck along the way, trying to reach ports that had not been built to attend that kind of demand. Brazil’s main ports, Santos and Paranaguá, were built in the late nineteenth century, to ship coffee produced in the states of São Paulo and Paraná, not soybeans and corn grown more than 1,000 miles away.Although southern states continue to be very significant in grain production, Brazil’s production map has turned upside down since the 1990s, with central and northern states becoming more and more important. Thirty years ago, they produced 36% of Brazil’s soybean and corn output. Now, they represent 61%.What Brazil needed, therefore, was to turn its logistics upside down too, avoiding, as far as possible, covering such long distances using only trucks. And some important changes have been made for a few years now, through private and public investment in road improvements, rail, barge and, last but not least, ports in the north of the country.Five years ago, the so-called “Northern Arc ports” shipped 19% and 12% of Brazil’s soybean and corn exports, respectively. Now in 2019, their share jumped to 32% and 33%. By the end of the year, 35 million metric tons of soybeans and corn will be shipped by the northern ports, compared to 11.1 million in 2014.That is a great achievement, no doubt. But much is yet to be done, especially when it comes to improving roads and railroads between producing regions and the northern ports. And investors seem to be interested in doing that, especially the Chinese, who recently announced infrastructure projects in the states of Maranhão and Pará. It might take time, probably several decades, to have something remotely similar to what the United States has. But it seems that Brazil has finally woken up.
Trying to search for old tweets can be a pain. Twitter’s own search engine brings back limited results and the top search engines like Google and Bing are so focused on real-time that trying to get something older than a couple of days is almost impossible. Often times you will find yourself scrolling through your timeline looking for that one tweet you sent months ago. If you tweet a lot, that is a giant hassle.PostPo.st thinks that it has come up with the solution. When you sign up for the service PostPost will determine 200 of your most relevant follows and index up to 400 tweets for each user. If some of the people you follow are also PostPost users then nearly all of their tweets will indexed. PostPo.st attempts to be as comprehensive a Twitter search engine that exists today.PostPo.st will not only bring you back search terms with your keyword in the tweet but it will also partially index the Web pages of the link that was tweeted. The example that Brad Noble, founder and product designer or PostPo.st, uses is that of “tsunami.”“Tweets are often terse. Especially those with links in them,” Noble said. “In order to account for that, we index not only the Tweets themselves, but also key parts of target pages. So, a search for “tsunami” can bring back Tweets that are about the ‘tsunami’ even though they don’t have the word ‘tsunami’ in them. Here’s an example.”PostPo.st stops the number of relevant followers at 200 because it is following Dunbar’s Number, the theoretical limit of the number of people with whom any one person can maintain a significant social relationship. This does two things: A) attempts to bring you the most relevant search results and B) takes a significant load off of PostPo.st’s servers. If PostPost did not truncate the number of relevant followers and tweets it indexes it would not provide the useful information that you are looking for and every search that you do the engine would be crawling everybody you follow and all their tweets. The end result would be a very poor search result.The interface of PostPo.st is not unlike a historical version of social media aggregator Storify that just went to public beta this week. If a user has posted a picture with a tweet, PostPo.st will open that picture in the search timeline the same way that Storify does when manually curating feeds. A good example of this was adult magazine Penthouse, which signed up for the service April 27 and tweeted a picture tweet search history for adult star Nikki Benz (no nudity, mostly safe for work).

The number of dials a salesperson makes is easily measured. So is the time they spend speaking with prospects and clients. The hours they work is also easily captured. You can also count the number of emails a salesperson has sent.The value of a potential opportunity is also easy to measure. Whether the opportunity is measured by revenue, gross profit, or margin, it’s relatively easy to determine the value of a deal.The days an opportunity has lived in a certain stage is very simple arithmetic. You subtract the date the opportunity entered the stage from today’s date to determine the number of days (or weeks, or months, or years if you allow your pipeline to be stuffed with what are actually leads).You can also verify that you have the necessary deals to reach your goals by ensuring that you have 300 percent of your goal in your pipeline at all times. This is easily measured and requires the smallest amount of math.While all of these measurements provide good and useful information, sales effectiveness cannot be collapsed into objective measures alone. The difference between success and struggling to produce results is found in more subjective measures, none of which lend themselves to objective measurement.Subjective Measurements and ContextHow effective is the salesperson making the calls or sending the emails? Is there enough value being created for the client who receives the communication to agree to their request for a meeting? If the results are not forthcoming, then focusing on objective measurements is of no use to you in making an improvement.The value of an opportunity, as easily measured as it may be, provides little to no information at all about the likelihood of your capturing it. It says nothing about how compelled the client is to change, how well the salesperson is doing helping them, or how susceptible you are to a competitive threat. You can only determine the real value of the opportunity to your organization by looking at more subjective factors.Why has a deal been in a stage for longer than normal? Why did a deal move through a stage faster than expected? Does more time mean the deal is at greater risk of being lost? Does less time mean that the deal is progressing fast because the client is seriously motivated to change or because they are skipping the commitments they need to make to really change?Objective measurements provide one small part of a much larger picture. Reducing everything to what can be measured is to ignore the subjective factors that give you a fuller picture of what is true. The subjective is more difficult to assess, but the conversations necessary to surface the subjective factors that can’t be easily quantified is how you improve your results.Qualitative measurements are what allows you to determine what the objective measurements mean.

Prime Minister Narendra Modi’s claim in his monthly radio programme Mann Ki Baat that he used to listen to “Rabindra Sangeet” — songs composed by Rabindranath Tagore — at 5.30 a.m. has created a controversy in the bard’s home State.Former All India Radio (AIR) officials and Opposition party leaders have questioned the claim.“Around 5.30 a.m., Rabindra Sangeet would play on radio and I had a habit of listening to Rabindra Sangeet waking up early in the morning. However, I didn’t know the language (Bengali),” the Prime Minister said in Sunday’s Mann Ki Baat. Former Assistant Director of AIR Kolkata Jagannath Basu said he was not aware of any radio station during that time (PM’s childhood) that broadcasted Rabindra Sangeet at 5.30 a.m. He pointed out that AIR Kolkata broadcasts Rabindra Sangeet in a programme at 7.45 a.m.‘Casual remark’“I am not aware whether any radio station broadcasts Rabindra Sangeet at that time (5.30 a.m). Everyone knows that Rabindra Sangeet is played on AIR Kolkata’s programme at 7.45 a.m. It was very popular back then,” Mr. Basu told The Hindu. Mr. Basu, however, added that perhaps the Prime Minister mentioned that time of 5.30 a.m. “casually” as it would be difficult for him to tell the specific time.Scoffing at the Prime Minister’s remarks, Trinamool Congress (TMC) general secretary and State Education Minister Partha Chatterjee said: “The Prime Minister’s remarks show that he doesn’t practice what he preaches. He should know when Rabindra Sangeet is played on radio. I really cannot understand what radio station he was talking about.”State Congress president Adhir Ranjan Chowdhury was sceptical about the Prime Minister’s comments. “I have never heard that Rabindra Sangeet was played on radio at 5.30 a.m. Hopefully, one can know through an RTI query,” he told journalists.‘Left with no issues’State BJP vice-president Sayantan Basu argued that the Opposition had no issues to speak about and hence were raising a hue and cry about the Prime Minister’s remark. “How do they know when Rabindra Sangeet was played on radio at that time (during Prime Minister’s childhood),” he asked.
With tent cards featuring little known para athletes, giant screens beaming para sports and waiters requesting guests to ‘adopt and sponsor’ para athletes, a pub in Kolkata is going the extra mile to promote para sports.Set up by IT and management professionals in the city’s Salt Lake Sector V area, Five Mad Men is a unique sports pub or “gastro play pub”, as the owners prefer calling it here, that focusses on making sports more accessible to people with disabilities.“When we decided on opening the pub, we knew that the theme would be around sports… We are trying to contribute to the sports scene in the country in our own small way,” Sayan Roy, one of the co- founders of the sports pub said.Spread over an area of 5,000 sq. feet, the sports pub can accommodate 450 people, and has one the biggest screen that any pub can boast of: 200 sq. feet.“Other than the giant screen, we have five big television screen playing different sports at any given time. Guests can also indulge in games such as poll, carom, foosball, dart boards, air hockey and X-box,” Sourav Sinha, another founder said.While the pub was launched a few months ago, the idea to promote para sports struck the founders earlier this month. As a beginning, they adopted two para athletes — Ajibur Rahman Molla and Sufia Molla — for one year and promised to take care of their nutritional and training requirements.They have also decided to charge ₹10 for each bill, which will be spent on the welfare of regional para-athletes.“Since we get around 200 visitors on a given day, we can set about ₹2,000 aside for the cause. The amount is enough for one para athlete’s nutritional and training requirements for a month,” Mr. Roy said. What is encouraging is that people are not turning down requests to pay extra. If all goes well, they may consider raising the amount in future. Shuvojit Moulik, founder of Civilian Welfare Foundation, who has worked with founders of Five Mad Men, pointed out that awareness about para sports in India is woefully low. “With initiatives like Five Mad Men, we hope to increase the awareness among the people,’” he said.‘Improves quality of life’Welcoming the initiative, Anusheela Brahmachary, a sports psychologists, said that sports can help in overcoming disability. Studies have shown that sports improves quality of life of people with disabilities and helps in their social inclusion.Sufia Molla, a national level para swimmer with hearing and speech disability and sponsored by the pub, said it is not just about individual athletes like her, but to all those people born with disabilities. Initiatives like these can instill confidence and help them compete in sports.
In-form Iraq dazzled yet again, blanking a rudderless Chile 3-0 to register their first ever win in the Under-17 FIFA World Cup and stayed firmly in contention for a knockout berth in the competition on Wednesday.The star of the day for Iraq was striker Mohammed Dawood, who scored a brace (sixth and 68th minutes). He missed out on a hat-trick when his penalty was blocked by goalkeeper Rodrigo Cancino in the dying minutes of the Group F game before a good crowd at the Vivekananda Yuva Bharati Krirangan.Chile’s Diego Valencia put the ball in his own net in the 81st minute to complete the misery for the South American outfit.Iraq, who had lost all their three group matches in their only previous appearance in the tourney in 2013, managed their first point on Sunday when they warmed their way into the fans’ hearts by holding two-time champions Mexico to a 1-1 draw.With four points from two games, the Asian U-16 champions now need only a draw against England in their last group game on Saturday to sail into the Round of 16.On the other hand, Chile are staring at the barrel having lost both their encounters, conceding as many as seven goals.FIFA Photo On Wednesday, Chile were under the pump from the beginning, conceding a goal early, with the dangerous Dawood firing a right footer into the net from an acute angle, despite being hemmed in by two Chile defenders. Dawood had failed to control the ball in his first attempt, but quickly recovered ground to excel in scoring his second goal of the tournament, that earned all round applause from the 40,000-plus crowd in the galleries.advertisementThe margin was doubled midway into the second half. The fleet-footed Dawood looked menacing as he almost managed to cut through two Chilean defenders, but was brought down by a desperate Martin Lara. Dawood himself took the free kick — a low one that swerved in to give the forward his third goal in the competition.Nine minutes from time, substitute Valencia struck an own goal following a corner from the left, sealing Chile’s fate in the game, and may be, in the tournament, as well.It was a completely one-sided match, with the Asian side making constant forays into the rival defence, and enjoying 68 per cent of ball possession in the first half, and 59 per cent overall,The Chileans, who made four changes to the starting line up that collapsed 0-4 to England three days back, seemed out of sort. They hardly managed an attempt at the Iraqi goal, as their attempts fizzled out in the rival defensive third.The Iraqis, who started on a rousing note, could well have doubled the lead in the 13th minute when Bassam Shakir latched on to a cross from Muntadher Mohammed and unleashed the left footer, but the ball was off target.Down 0-1 at the break, Chile tried to show more purpose in the initial minutes of the second session, but Antonio Diaz’s left footer narrowly missed the target.But Iraq seized the initiative soon after, with Dawood coming close to scoring in the 50th minute.The highly-rated striker in fact could have finished off the day with a hat-trick, had he managed to score from a penalty in stoppage time, after he was brought down inside the box. However, Cancino fisted off the set-piece, and the rebound landed on the roof of the net.
