Scientists are beginning to get at least partial answers for scientific mysteries by carefully observing and testing to see how things work.Waving corals. Some soft corals pulsate regularly. Why is that? Why would they perform motion that is energetically costly? PhysOrg reported that scientists at Hebrew University of Jerusalem wanted to solve this “old scientific mystery.”One of the most fascinating and spectacular sights in the coral reef of Eilat is the perpetual motion of the tentacles of a coral called Heteroxenia (Heteroxenia fuscescens). Heteroxenia is a soft coral from the family Xeniidae, which looks like a small bunch of flowers, settled in the reef walls and on rocky areas on the bottom of the reef. Each “flower” is actually a living polyp, the basic unit which comprises a coral colony. Apparently, the motion of these polyps, resembling flowers that are elegantly spreading out and closing up their petals, is unique in the animal kingdom.Researchers found that the corals take a “siesta” for a half hour every day. They will also stop pulsing for a few minutes after being touched. By measuring the water flow around the corals, the researchers found that the pulsations effectively stir the water around these filter feeders to enable new nutrient-rich water to flow in. It also removes excess oxygen and brings in carbon dioxide, raising the rate of photosynthesis for symbiotic algae. “The findings of this study indicate that pulsation motions are a highly efficient means for sweeping away water from the pulsating body, and for an increased mixing of dissolved matter between the body and the surrounding medium,” the report said. The answer to this biological mystery was not just for curiosity: “These two processes (expulsion of medium and mixing of solutes) may lead to future applications in engineering and medicine.”Baby turtles: Surely everyone who has watched TV footage of baby sea turtles scurrying across the sand toward the water thinks it’s cute. Scientists agree, but ask questions beyond: how do the turtles travel so effectively, several body lengths per second, across soft sand? Science Daily tells how researchers at Georgia Tech tried to mimic the action with “Flipper-Bot,” a robot with paddle-like limbs (see video of the turtles and the robot on YouTube). A Georgia Tech biologist first filmed the hatchlings traveling toward a light at night. Their clumsy-looking limbs are actually quite effective at scurrying over sand without moving it much. They can control their wrists depending on the medium. “On hard ground, their wrists locked in place, and they pivoted about a fixed arm,” the scientist explained. “On soft sand, they put their flippers into the sand and the wrist would bend as they moved forward.” A robot model proved this is a good way to travel; it gives a high angle of attack, and reduces drag. The article suggested that the new information “could ultimately provide clues to how turtles evolved to walk on land with appendages designed for swimming,” but one of the researchers quickly admitted, “We don’t have solid results on the evolutionary questions yet….”Homing pigeons: A mystery of bird navigation is closer to being solved. PhysOrg reported that Viennese and Australian scientists have “added some important pieces” to the puzzle of how birds navigate, a skill that allows some species to span the globe on the wing. It turns out every bird (but not humans) has little iron balls in sensory neurons. “Remarkably, each cell has a single iron ball, and it’s in the same place in every cell,” they noted. Even ostriches have them. Perhaps these are the “elusive magnetoreceptors” that respond to the earth’s magnetic field. A previous theory has been discredited. It turns out that iron-rich clusters thought to exist in pigeon beaks were just blood cells. If the iron in the sensory neurons is involved in birds’ magnetic sense, scientists still do not know how they work: “we’re a long way off understanding how magnetic sensing works,” one of the scientists said; “we still don’t know what these mysterious iron balls are doing.”The classical “scientific method” of observation, hypothesis, and testing can answer questions about “how things work” if they are amenable to repeated observation, as in these cases. Stories about “how they got that way” by evolution are far less useful. When scientists approach things as if they work for a purpose, whether coral pulsations or turtle flippers, they usually get two rewards: satisfying explanations that can bear repeated testing, and applications that can improve human life. Liberate these scientists from the ball and chain of having to add a Darwinian just-so story to their work.Speaking of birds, a great new film on bird flight is coming from Illustra Media. Watch for the news here. It contains a truly stunning story of migration, as well as other cutting-edge findings that were obtained by good observational scientific methods. The film will illustrate a common experience in scientific research: when scientists look more closely at natural phenomena, they usually find answers that are far more dynamic and wonderful than previously thought: answers that transcend language and cause us to stand in awe.
The Aligarh Muslim University Students’ Union has welcomed the decision of the All India Muslim Personal Law Board (AIMPLB) to file a review petition challenging the Supreme Court’s Ayodhya verdict. A statement issued by AMUSU president Salman Imtiaz said the verdict “appeared one-sided in the conclusion.”“We consider the building of the temple over the land of the mosque as a humiliation, injustice, and subjugation of Muslim minorities. It appears a step towards the creation of Hindu domination in India wherein Muslims will be rendered to second-grade citizens,” Mr Imtiaz said.He further said the AMUSU was committed to the cause of Babri Masjid, and it would never allow India to lose its constitutional core. “We are happy with many details in the judgment that have strengthened the constitutional framework of the nation, and outrightly rejected Hindu chauvinism,” the statement said.

It’s official: Amar’e Stoudemire is a New York Knickerbocker no more. The team waived the veteran forward Monday, ending his Knicks tenure midway through his fifth season with the club (one in which he’s due $23.4 million in salary).ESPN’s sources reported that the Dallas Mavericks are waiting in the wings to pick up Stoudemire for the stretch run, provided he clears waivers Wednesday evening. But before he signs with Dallas, it’s worth stopping for a moment and asking: Where does Stoudemire’s ill-fated Knicks contract — he was doomed by bad knees — rank among the NBA’s worst (if not ever, at least in recent memory)?It’s not particularly simple to assess the value of NBA contracts for a number of reasons, many data-related, so consider this a very approximate effort. Stoudemire has produced 8.1 wins above replacement (WAR) over the previous five seasons, during which he’s been paid a total of $99,743,996 (both numbers include the 2014-15 season). About $95.4 million of that was paid above what the Knicks could have delivered to a replacement-level (zero-WAR) player making the NBA’s minimum salary,1Using the minimum salaries listed here for players with at least two seasons of NBA service. so effectively New York paid about $11.8 million for each of Stoudemire’s wins above replacement during his stay in the Big Apple.Needless to say, that wasn’t a bargain. Using Basketball-Reference.com’s transaction database, it’s difficult to discern actual trades from free-agent signings that utilized the sign-and-trade mechanic of the NBA’s collective bargaining agreement. But all players who were either traded or signed as free agents between May and October 2010 (a group that includes Stoudemire and any other blockbuster free agent) were paid $1.4 billion to produce 509.4 WAR. At the going rate, that means it would have been reasonable to expect Stoudemire’s $95.4 million to turn into 33.7 WAR. By this accounting, Stoudemire’s production since the 2010-11 season fell short of his expectations by 25.6 WAR.As a comparison, LeBron James, the biggest-name free agent signed the same summer, was paid $83.4 million above the minimum over the ensuing five seasons (granted, not all of it by the same team under the same contract), which would seem to portend 29.5 WAR; instead, James posted 82.8 WAR for a surplus of 53.3 WAR.The bargaining agreement contains various arcane provisions that often result in tragicomic salary leaderboards.2Between Stoudemire, Kobe Bryant, Joe Johnson, Carmelo Anthony and Dwight Howard, the league’s five highest-paid players have produced fewer WAR together (9.5) than either James Harden or Stephen Curry have by themselves this season. But Stoudemire’s disappointing play stands out as particularly egregious. And it isn’t like there aren’t other contenders for the “worst contract” crown. For example, the Detroit Pistons in 2009 signed Ben Gordon to a five-year, $55 million deal that saw him deliver a below-replacement level -3.5 WAR — yet even Gordon’s 23.8-WAR shortfall was not as bad as Stoudemire’s.According to this method of comparing actual five-year WAR to expected WAR from salary, Stoudemire’s signing ranks as the worst offseason acquisition3Lumping in trades and free-agent signings out of necessity since the summer of 1996, when Basketball Reference’s transactions begin to be relatively complete. Here are the particulars of his badness, along with the next 29 worst offseason prizes of the same span:

This investiture is the largest the Mission here in the Turks and Caicos Islands. The theme for the joint service was “Lord, transform me for your service”.The Minister of Education, Youth, Sports and Library Services, Hon. Connolly, attended the event and brought remarks on behalf of her Ministry. She said; “It is my pleasure to bring greetings on behalf of the Ministry of Education, Youth, Sport and Library Services at this very important ceremony. I want to acknowledge all of the elders and leaders of the Seven Day Adventist Church who are here with us today to support all of these amazing young people. Today you are making a very important public commitment. You are making a commitment to service, service to your God, your church, your community and your people. I congratulate you! I am proud of you!”She further told the youth present that; “I understand that the Pathfinders Club is a very well established and important one for the Seventh Day Adventist Church. When I heard of the work that you do with young people, assisting with homework, conducting evangelism, visiting the children’s home and giving of your time and talents to our country, I was more than proud of you and even more elated to be here.“Willingly engaging in service is a commendable act. This will prepare you well for the future, not only on your CVs but for leadership on a whole. The Bible itself admonishes that if you want to be Great in the Kingdom, you must be a servant of all! Indeed, we are admonished in 1 Peter 4 verses 10 and 11 to ‘use our gifts to serve one another, so that God may be Glorified’. You heeded that call!”She encouraged the gathering of youth by reminding them that they have a role to play in today’s society. She told them that; “You are powerful and you have potential! Remember David was only a boy when he killed a giant, Jehoash was 7 years old when he became King of Judah and Josiah was 8 years old when he became King in Jerusalem. Look around you, Look at how many people have invested in you being here; your parents, your minister, your teachers and your friends. You have to take the opportunity today to encourage one another.”“I look at you and I am reminded that today’s youth are the leaders of tomorrow. Each of you have something that you are destined to do, whether that is raising a beautiful family, succeeding in a profession, being CEO of a large cooperation or leading your community into a better future. You all have a role to play. We, The Turks and Caicos Islands, need you. As you move forward in your journey towards being an adult, a responsible citizen of the Turks and Caicos Islands, I want you to remember that you are never alone.” Hon. Connolly stated that she enjoyed the event and the participation of the youth in the service. She left words of encouragement for the youth at the service and hoped that she was an inspiration to them. She said; “I want to leave these few words of encouragement with you because I know as young people, involved in community work you will have some challenging times. When you feel discouraged or heartbroken, ask God to transform you so that you can be of service to Him.“Concentrate on what God is calling you to do rather than the naysayer’s personal agendas. You will struggle with this all your life, so the sooner you discipline yourself the better. Just like Elijah, you probably have more supporters than you think you have. Hang around positive-minded people, people you trust and who trust you, to help you continually mature as a person and leader.“I’m so proud of all of you here today. I’m proud of this gathering. I know you all can move forward with God as the center of your life. Live to serve Him. I believe in you, and I can’t wait to see everything you all will achieve for your generation and generations to come.” Recommended for you The Luxury of Grace Bay in Down Town Provo

Kolkata: This is a sight which one can behold only in the City of Joy. When the fire-fighters were giving their best to douse the devastating fire at Bagree Market, a group of locals came forward to support them by distributing water, food and tea.It was from almost 3 am on Sunday that the fire-fighters were battling hard to control the fire. They worked under an extremely difficult situation with heavy smoke billowing out of the windows of the building. Additional policemen were also deployed at the spot to ensure that the fire-fighters could work without facing any difficulty. Personnel of the Disaster Management Group were also there to restore normalcy at the earliest. Also Read – Rain batters Kolkata, cripples normal lifeApart from the men in uniform, another set of people were found working relentlessly, distributing food and water among those who were battling the blaze. The firefighting continued for more than 19 hours and the group of people had been working since morning. In a bid to ensure that the rescuers get food, around 500 packets containing pulao were distributed. Again, in the evening, tea was distributed and another 1,000 food packets were distributed after sundown. It may be mentioned that whenever there is any such situation, a good number of people from the city come together to carry out such works. The same thing was witnessed when the Vivekananda Flyover collapsed and the rescue work continued for three to four days. Food and water were distributed so that people working at the spot could get some food as and when required. Some locals from Ekbalpore came to the site where the Majerhat bridge caved-in on September 4 and they were found distributing cakes, biscuits and water among the rescuers.
