Darwinian Dogma Doubted: Cave Fish Go Blind on Purpose

first_imgContrary to previous belief, blind cave fish have the genes to build eyes but turn them off during development, reports Science Now. When a body part is no longer needed, scientists usually assume that mutations accumulate in the genes controlling the structure, eventually preventing it from working or being made.  “That was the dogma,” says Stephen Ekker of the University of Minnesota, Twin Cities.  But because the cave fish eyes are actively killed, natural selection is probably doing its thing, says Jeffery.  And that, he adds, might come as a surprise even to Darwin, who thought the cave fishes’ loss of sight might be an exception to the rules of natural selection.  The next step, of course, will be to figure out what the fish gain by losing their sight.So it’s not simply an issue of “use it or lose it,” the article states; “new research suggests that for some cave-dwelling fishes, blindness results from the careful coordination of gene expression, not simply from lack of use.”    Science News also reported this story, describing how the researchers could induce blindness in sighted fish by controlling the expression of a gene, and could partially restore sight in blind fish with different gene regulation.  The article ends, “Because the genes orchestrate both mouth and eye development, the blind fish may have lost their eyes as t hey gained a more effective mouth—a useful feature for catching food in the dark.”Creationists have argued that natural selection eliminates things, rather than constructing them, so this is no surprise.  What is surprising is that the eyes did not merely degenerate through disuse, and that the response could have occurred quickly through changes in the regulation of one gene during development.  Maybe there is a functional reason why this gene is being switched off in the darkness of the cave environment.  Maybe with eyes not in the way, it helps enhance the other senses the fish will need when sight is not possible.  Whatever the reason, natural selection cannot be credited with creating new function, because both eyes and mouths already functioned well. (Visited 37 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Report: Four Programs Lobbying Big 12 For Expansion

first_imgThe Big 12 Conference's logo.With lots of chatter surrounding Big 12 expansion, we’ve already brought you our opinion on how the next phase of conference realignment could unfold. Now, ESPN has some intriguing information regarding which schools the Big 12 could target if it does indeed expand. According to Big 12 writer Jake Trotter, four institutions have already begun lobbying the Big 12 for consideration: Houston, Memphis, UCF and Colorado State. From Trotter:With Big 12 expansion back on the table, officials from the University of Houston, the University of Memphis, University of Central Florida and Colorado State University have been lobbying members of the Big 12’s composition committee, according to documents ESPN.com has obtained.West Virginia president Gordon Gee is one of three Big 12 presidents on the committee, which is charged with exploring expansion candidates. Documents reveal that Gee has been busy in that role in recent months, which has included a trip to the University of Houston in late November.Additionally, Trotter says FedEx, which is headquartered in Memphis, is offering major sponsorship of Big 12 football and basketball if the Tigers are added to the league. This was originally part of Memphis’ pitch to the old Big East a few years back. Documents obtained show FedEx primed to back Memphis’ Big 12 candidacy, prepared to sponsor Big 12 title game: https://t.co/Fa8jbDEbwS— Jake Trotter (@Jake_Trotter) May 10, 2016The most interesting aspect of Trotter’s report? Probably that UConn and Cincinnati are nowhere to be found, considering those are two schools many have linked to the Big 12, including us here at College Spun.  Also, would Oklahoma and Texas, the two premier programs in the league, really be okay with these additions? Or would they look to bolt for greener pastures? Whatever the answer, buckle up because the realignment well may start turning fast and furiously. [ ESPN ]last_img read more

Ohio States Devin Smith separates from Buckeyes receivers

Devin Smith might be the best wide receiver Ohio State has. The sophomore playmaker has looked the part through the first three games of the season, catching 13 passes for 233 yards and three touchdowns. He had a one-handed touchdown grab against Miami (Ohio) that will be played on highlight reels for years to come and the game-winning score against California last Saturday. The statistics and big plays might speak for themselves, but they don’t have to anymore. “(Tuesday) at practice, coach Meyer was talking to the team, and he told me that he feels I’m the best receiver in the unit,” Smith said, as he cracked in to a smile. Smith’s quarterback, sophomore Braxton Miller, said he agrees with Meyer. What separates Smith from his teammates, Miller said, is a little bit of everything. “First of all is his speed. He has great hands. I’d say his routes too, the way he gets open, he gets open really fast,” Miller said. Smith’s attributes have certainly been on display during OSU’s first three games this season. What has possibly stood out most, though, has been his ability to go up and pluck balls out of the air. That skill is what allowed Smith to make his one-handed catch against the RedHawks, and it is the cause for one of his two touchdowns last Saturday against the Golden Bears. The skill is not just something Smith possesses; it is something that is preached to all of the OSU wide receivers every day at practice by wide receivers coach Zach Smith, but the sophomore wide receiver probably does it best. “Whenever the ball is in the air, it’s yours. That’s our mentality with this group,” Zach Smith said. “Every time the ball is thrown to us we have to go get it.” Devin Smith has had a few low moments so far this season too, including two dropped passes last Saturday against California. His hands are something he said he works on heavily. “My hands are pretty good. I work on them every single day. Those two drops in the game, it happens. You got to bounce back and my teammates did a great job keeping my head up,” Devin Smith said. While Devin Smith has received a good amount of praise recently from his coaches and teammates, the positive reinforcement has not always been there. Outside of a game-winning catch against Wisconsin, Devin Smith’s 2011 freshman season was fairly unmemorable. He had 14 catches, one more than this year’s total three games into the season, and 294 yards, a mark only 61 yards higher than his current output this season. Meyer said he was not extremely impressed with Devin Smith when he first arrived at OSU. “I did compliment him (Tuesday) because he’s a different guy. He was nothing like this in spring ball,” Meyer said. Devin Smith has come a long way since the spring, and even since the beginning of the season, according to Meyer. “He had a good week. He’s one of … I just hate to say this because they turn backwards sometimes, but he’s really done a nice job. He’s a pleasant guy to be around,” Meyer said. The high praise given to Devin Smith by Meyer this week has made the sophomore wide receiver hungrier for more success. “Ever since (Tuesday), I’ve approached the game differently, now that (Meyer) feels I’m the best receiver on this team,” Devin Smith said. His approach to the game now centers on what he can do to help the team apart from just catching passes. “Just making sure I’m doing everything I can for this football team, no matter what it is – blocking, running routes, whatever it is I can do for this team,” Devin Smith said. Smith’s approach to the game is set to be on display Saturday against Alabama Birmingham. Kickoff is scheduled for noon at Ohio Stadium. read more

With raised sprits Ohio State mens basketball focuses on Penn State

Junior center Amir Williams dunks the ball during a game against Iowa Jan. 12 at the Schottenstein Center. OSU lost, 84-74.Credit: Shelby Lum / Photo editorThe night is darkest before the dawn, and for the No. 24-ranked Ohio State men’s basketball team (16-4, 3-4), that dawn might have arrived.After struggling through a four-game losing streak — the program’s longest since February 2008 — the Buckeyes got back on track with a 62-55 victory against Illinois last Thursday.Freshman forward Marc Loving said just getting a win helped raise spirits in the locker room.“Our moods are definitely a lot lighter than what they were during the four-game losing streak,” Loving said Tuesday. “I would say there’s been a lighter load going into the next game. I feel like a weight’s been lifted off of us, get a little monkey off our back. Going into this next game, we definitely have a mindset that we’ve got to execute and get stops defensively because that’s what we key on.”It’s been more than two weeks since OSU headed into a game off a win, and some players are hoping their problems have been fixed.Junior center Amir Williams, who saw his minutes decline during the losing streak, said a lot of time in practice has been dedicated to two things: defense and shooting.“We spent a lot of time these past few days working on our defense and a lot with our shooting,” Williams said Tuesday. “That’s mainly been a problem that we’ve had in the past, guys were just driving by us and not playing our principles on defense so we just got back to the basics and broke down what we had to do defensively to keep teams from scoring against us and just get up a lot of shots offensively. We’ve been putting a lot of time into shooting the ball.”Williams added that another four-game losing streak has to be prevented at all costs for a team with as high of goals like OSU’s.“We can’t take any team for granted,” Williams said. “This is a tough conference to play in night in and night out so we’re going to continue to build … That four-game losing streak is something that can’t happen to us again. We’re going to have losses and we’re going to win some games but we can’t just not show up to play like we did those last four games.”Next up, the Buckeyes are set to take on Penn State (10-10, 1-6) and will be hoping to contain their leading scorers, redshirt-junior guard D.J. Newbill (17.2 points per game) and graduate-senior guard Tim Frazier (16.5 points per game).OSU coach Thad Matta said despite the Nittany Lions’ record, they will not be overlooked by the Buckeyes.“You look at Penn State, they’ve been in every single game they’ve played this season and had some of the craziest losses I’ve seen in terms of the ball didn’t bounce their way,” Matta said Tuesday. “Obviously Frazier and Newbill have shown, not only this year but throughout their career, that they can go into an arena and get 30 on you … but you get a pretty good feel of who they’re trying to get shots for and we’ve got to do a pretty good job of locking those guys down the best we can.”The last time OSU lost to Penn State was Jan. 10, 2004. Tipoff is scheduled for Wednesday at 7 p.m. at the Schottenstein Center. read more

Borough Looks At Switching To Borough Manager

first_imgCooper: “This ordinance is something I have believed in for a very long time. We have had mayors in this borough that were very qualified and we’ve had mayors that were not. So this is not an attack on this administration solely.” A public hearing will be held at the borough meeting on Tuesday. If it passes the assembly the question would go on the fall ballot for voters to decide on October 1. Facebook0TwitterEmailPrintFriendly分享The Kenai Peninsula Borough has begun to scratch the surface on a debate on whether or not to move towards a borough management style instead of the current mayor style. In a ordinance put before the borough assembly, under a manager form of government, the mayor would still be elected areawide but no longer be the chief administrator of the borough. Instead, a borough manager would be appointed by majority vote of the assembly on the basis of administrative qualifications to serve as the chief administrator. center_img Currently, twelve of the state’s 19 boroughs employ a manager to administer day-to-day operations versus a mayor. The ordinance was introduced by Assemblywoman Kelly Cooper, and Assemblyman Hal Smalley. The mayor would serve as chair of the assembly, still be able to participate in assembly discussions, may vote on assembly actions in the case of a tie, and may veto assembly actions, according to the ordinance. last_img read more
