Worm Genes Show Non-Evolutionary Pattern

first_imgBiologists at New York University compared genes of roundworms to look for evidence of evolutionary ancestry.  What they found was not what they expected.  They found more genetic variation between outwardly-similar worms than between mice and men.  Their results were published online in PNAS June 7.1    The roundworm Caenorhabditis elegans is a model lab organism for genetic studies.  Kiontke et al. compared it with 7 other worms of the same genus and four other related species.  They first devised a family tree of the worms, based on commonly-accepted phylogenetic techniques.  Despite the fact that only subtle morphological differences exist between most of the species, they found major differences in intron counts (with intron loss apparently much more frequent than intron gain).  They also deduced that a specialized form of hermaphroditism (ability to self-fertilize) evolved separately in two species, C. elegans and C. briggsae, by convergent evolution.  Summarizing all the differences they found, they stated with obvious surprise that “despite the lack of marked morphological diversity, more genetic disparity is present within this one genus than has occurred within all vertebrates.”    The amount of genetic diversity between these worms is all the more surprising considering the impact one change can sometimes have.  In another paper published in PNAS the same day,2 a team of scientists studied a genetic disease called progeria that makes children die of old age at 13.  The disease is caused by a single point mutation in one spot, the lamin A gene, that is important in maintaining the structure of the nucleus.    Why the worms show so much genetic diversity despite little outward visible difference was puzzling to the biologists.  They postulated it might be due to stabilizing selection (influences that, despite genetic changes, produce results analogous to treading water or running in place).  Alternatively, “developmental constraints may limit the ‘evolvability’ of Caenorhabditis,” they suggested.  Or maybe the worms’ molecular clock ticks at much higher rates than in higher organisms, although they dispute the idea.    They leave it as an unsolved puzzle how similar-looking worms could show more genetic diversity than vertebrates (including mice, rats, hamsters, zebrafish and humans).  “It had been noted previously that the genetic distance between humans and chimpanzees seemed too small to account for their substantial organismal differences.  However,” they observe, “the situation is strikingly reversed in Caenorhabditis.”1Kiontke et al., “Caenorhabditis phylogeny predicts convergence of hermaphroditism and extensive intron loss,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0403094101, published online before print June 7, 2004.2Goldman et al., “Accumulation of mutant lamin A causes progressive changes in nuclear architecture in Hutchinson-Gilford progeria syndrome,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0402943101, published online before print June 7, 2004.Molecular phylogenetics is not providing the evidence of common ancestry for which evolutionists had hoped.  Since it looks like an exercise in futility, can we move on to better things now?

OSU won, 34-24.Credit: Shelby Lum / Photo editorThe No. 24 Ohio State women’s volleyball team is looking to put a halt to a five-match losing streak, but will have to take down another top-15 opponent to do it.The Buckeyes, in the midst of a 2-7 start to Big Ten play, are scheduled to face No. 13 Nebraska at 7 p.m. at St. John Arena.Coming off a three-set loss to No. 2 Penn State, freshman setter Maggie Heim said in an email that she and her teammates will have to keep their heads up in order to end their losing streak.“Keeping a very positive demeanor both on and off the court is huge,” she said. “Our energy and passion for the game will play a big role in a quick bounce back.”Heim said the 3-0 loss at Penn State “revealed many things that we need to work on.” She also said she has “no doubt” the Buckeyes will be able to get back in the mix by the end of their conference schedule.OSU started the season 12-0 in non-conference play before dropping then-No. 10 Michigan at home in its first Big Ten match, but have since slid down not only the conference rankings, but the American Volleyball Coaches Association Top 25 Poll.A win against Nebraska is likely the only thing that could keep the Buckeyes, once ranked as high as No. 12, from falling out of the poll completely.While it would help the team’s standings, junior setter Taylor Sherwin, who has recently been splitting time with Heim, said in an email it would “feel awesome” and spark the team for the rest of the season if they could get a win against Nebraska.Junior defensive specialist Alyssa Winner said in an email a victory over Nebraska at home would feel even better than beating the Cornhuskers 3-1 on their home court last season.In the short term, the Buckeyes recognize that they have to improve their offensive efficiency. The team hit minus .030 in the loss to Penn State, and Winner said they know how to get it done.“Keep working as a team on our tempos and holding blockers on the other side of the net to get open looks,” she said.Heim said the Buckeyes have to take a new mindset heading into the Nebraska match.“Playing with a chip on our shoulder like we have nothing to lose will also help,” she said.While the Penn State match marked the end of three games on the road, OSU will only be back in Columbus for a single match. The Buckeyes head back out on the road for matches against Michigan State in East Lansing, Mich., Nov. 1. read more

ESPNs Stephen A Smith talks sports journalism and the game of life

ESPN’s Stephen A. Smith spoke to students at an event hosted by OUAB on March 30 at the Ohio Union. Credit: Courtesy of OUABIn a collaborative event with Block ‘O,’ OUAB hosted ESPN personality Stephen A. Smith Thursday night at Ohio State.In front of a sold-out crowd of more than 1,700 people at the Archie Griffin Grand Ballroom in the Ohio Union, Smith spoke to those in attendance about ESPN, journalism in the 21st century, and the ‘game of life.’Prior to his talk with moderator Dr. Lanier Holt — an assistant professor in the School of Communications — Smith sat down with The Lantern for an exclusive interview, covering a number of topics, including why he first started in the sports industry.“If you are about the business of acquiring information, then you’re prepared for anything,” Smith said. “It came down to my abilities as a journalist, my ability to acquire information and to be in constant pursuit of the truth. As long as I’m doing that and I’m fair-minded and morally sound in the process, then I’m good.”Smith has long been known as an impassioned, no-nonsense personality. His career changed in 2012 when he joined ESPN’s First Take, a sports debate show that allowed Smith to fully showcase his talents.He continues to be a staple of the show to this day despite the departure of former co-host Skip Bayless.“I enjoy it,” Smith said. “I have a career, and there’s a difference between a job and a career. A job is doing what you have to do to maintain and elevate your quality of life. A career is doing what you want to do. It just so happens to do the same as a job. That want to is incredibly important because then you don’t feel like you’re working, so you’re in position to do more things.”It’s no secret that Smith has been the subject of much controversy throughout his career, controversy that began well before his time with First Take. While his straight-shooter approach might have made him a lightning rod of sorts, there isn’t a single thing Smith would change about himself.“It’s very, very important to me,” Smith said. “It’s what built my career. I wasn’t this way when I got on television. I wasn’t this way when I became a columnist. I became a columnist and got on television because I was this way. That’s what got me here. I don’t want to be any other way, and I make sure my audience knows that every time they see me.”Smith added that he understands why some think his takes are controversial.“I’m fearless, and it seems as though some think I don’t take the ramifications or consequences into consideration. They’re wrong, I do. I consider everything. I just believe that the truth will set you free. The closer I get to the truth, the better I feel. If I feel I’m being phony in any way, literally a sickness overcomes me.”When his talk with Dr. Holt began, Smith provided a backdrop of who he was and why he was speaking at OSU.“I don’t run from anything,” Smith said. “A lot of times when you see hesitancy in some matters, that’s ESPN, not me. They want you to monitor what you address and how you address it. My response to them is that it’s all intertwined. There’s no separation between sports and the outside world.”Smith graduated in 1991 from Winston-Salem State University – a historically black college in North Carolina – and soon began his career as a sports journalist. He emphasized the importance of getting a college education, which is a validation of potential in his eyes.“You need to understand that you’re here to get an education,” Smith said. “Your degree is a piece of paper that says you can read, write, and comprehend. It validates and authenticates your potential. What you do with it is on you.”Getting that degree is the easy part, though. It’s the mentality that you adopt afterwards that’ll make the difference between success and failure in life, Smith said.“Everything in life comes with a price,” he said. “You can pay now, or you can pay later, but you’re going to pay. The sooner you adopt that mentality, you’ll have a one-up on everyone else. The real world that awaits, and they don’t care about you. It’s filled with the haves and have nots, and there are a lot more have nots floating around.”Switching gears midway through the night onto Ohio sports, Smith stated that the Cleveland Cavaliers LeBron James is not only the best small forward to ever play in the NBA, but that Buckeye fans need not worry about the future of their football team.“I’m not worried about it,” Smith said. “(Coach) Urban Meyer is 61-6 since he’s been at OSU. I imagine that they can win the National Championship. I expect it to be between OSU and Michigan for the Big Ten title. You have (an) elite program here. ”Smith ended the lively night with a question and answer session with the crowd. It was the inside details about his personal life that made the biggest impact on second-year sophomore Wyatt Crosier.“I kind of thought it’d be all about sports,” Crosier said. “I really liked how he really motivated me. He was really funny, and I loved the event’s format. It was a great night.”As the crowd continued to hang on Smith’s every word, he delved deeper into his beliefs and personal life. Smith didn’t mince words when describing why he is the way he is.“I was born with a passion,” Smith said. “I mean what I say and I say what I mean. I try to speak intelligently and I don’t make excuses. Reasons are reasons why things happen. Excuses are made when you’re trying to get absolved of what you’ve done. I’m not trying to get anything absolved.” read more

Totti tells a crazy story involving jail

first_imgThe Italian legend was visiting a prison and one fan volunteered to stay one more week in order to meet the former Roma footballerFans can go to great lengths to show their support for their teams.Others will go crazy if they get to meet their heroes in real life.And that’s what Italian football legend Francesco Totti remembers about a prison visit, where a fan volunteered to stay longer to meet his idol.The former Roma star tells in his book how in 2006 he visited Rebibbia prison in Rome with the whole squad.Rick Karsdorp, Roma, Serie AKarsdorp reveals he had too much stress at Roma Manuel R. Medina – September 14, 2019 The Dutch defender has been with the Gialorrossi since 2017, but he has not enjoyed his time in the Italian Lega Serie A.“We went to visit the prison and take a tour of the cells, where everyone was detained. Everyone was very happy because for them to see a player inside was like seeing the Pope,” he was quoted by The Daily Mail.“There was this lad there that kept shouting, ‘Me! Me! Me!’ and wanted, at absolutely all costs, to take a photo with me. No-one would let him through, but he started to push his way forward and try and get closer to me to take a photo. I did not really understand why he was so determined.”The inmate was scheduled to be released one week before Totti’s visit, but he wrote a letter to the prison warden begging him to allow him to stay.“Even if I lived for another 100 years, I’ll never again have a chance like this to have my photo taken alongside Totti,” the inmate wrote in the letter.last_img read more
