Ohio State swimmers Lindsey Clary and Liz Li take success into NCAA


OSU junior Lindsey Clary poses for a picture at the Big Ten championships. Credit: Courtesy of OSUThe last time the Ohio State women’s swimming and diving team had a better performance at the conference championships than it did last month, no members on the current roster were born.Thanks in large part to two standout meets from junior Lindsey Clary and sophomore Liz Li, who secured two individual titles each, the Buckeyes took fourth place as a team at the Big Ten championships. Now they’re looking to repeat that success as they compete at the NCAA championships in Atlanta from March 16 to 19. Overall, the Buckeyes took home five titles, including one relay win — the first time since 1991 that the Buckeyes won a Big Ten relay event. Li, along with classmate Macie McNichols and seniors Annie Jongekrijg and Rachael Dzierzak, won the 200-yard freestyle relay, beating their own school record, while setting a pool record in the process. To add the icing on the cake, the relay team’s winning time also qualified it for the national championships.Clary had qualified for nationals at the Ohio State Invitational in November, so her training program was adjusted to have her be at her peak in Atlanta. As such, she went into the conference meet at a disadvantage relative to the other swimmers. Even though she didn’t have much to gain personally, Clary said she used the opportunity to accumulate points for her team as a catalyst to drive her.“Going into Big Tens I knew that I was in spots to score for my team,” Clary said. “I kind of used that as motivation, I knew I was in a good spot rested or not, I knew that I could get the job done.”She broke the pool record on her way to the Big Ten title in the 400-yard individual medley with a time of 4:03.64. She now enters the NCAA championships as the second seed.“My coach and I have talked a lot about how I’m going to be in the mix for the (national) title for the 400 (individual medley),” Clary said. “It’s definitely never even been a thought for me, so when my coach said that in the fall in one of my goal meetings I was like, ‘(Wow), he’s crazy.’ But I guess seeing the psych sheet and seeing what I did at Big Tens with little to no rest, it really pumps me up, so I’m pretty excited to see how that plays out, as well as my mile and 500.”Clary also won the 1,650-yard freestyle — the mile — and is seeded third in the event heading into the national championships. She took third in the conference in the 500-yard freestyle, which results in her qualifying for the NCAAs in that race, as well.As for the other Buckeye who won two individual titles, Li said she fell ill while resting for the conference championships, but she used inspiration from her teammates and coaches to gain confidence heading into the meet.“I was really sick, and I got tired mentally and psychologically. I felt like I might not perform well during Big Tens,” Li said. “I was so concerned about that, but my teammates and the coaching staff encouraged me, and they believed in me that I could do a good job.”OSU sophomore Liz Li poses for a picture at the Big Ten championships. Credit: Courtesy of OSULi won the 50-yard freestyle with a time of 21.80 seconds and is the second seed in the event at the NCAA championships. This was the first time that a Buckeye had won the Big Ten 50-yard freestyle title since 1982.Not being the top-ranked swimmer in the event isn’t necessarily a bad thing, Li said. “I feel like maybe that’s a great opportunity for me to improve myself, because I love people in front of me who are faster than me to lead me to my best,” she said.The sophomore also captured the conference title in the 100-yard butterfly and will be the No. 12 seed heading into the national championships. In her third event at the conference meet, she was out-touched in the 100-yard freestyle and had to settle for second place, but she will have another shot as the eighth seed in Atlanta.Clary said she thinks the team’s resurgence is because of a change within the team atmosphere, which has been a focus for the Buckeyes this season.“We’ve brought in a lot of outside aspects to help our culture and just team building and bonding with each other,” Clary said. “We’ve made that more of a priority, and I think the team has really bought into the program and the process.”OSU coach Bill Dorenkott credited good personnel and individual discipline outside of practice and competitions as the reason for the team’s success this postseason.“It took a while to get the culture where we want it, and that’s an everyday process,” Dorenkott said. “The decisions that the girls are making away from the pool, there’s a cumulative effect there, and you’re seeing the results of that. It just took a while to get the right people in the program and fit them into the proper roles.”The season doesn’t end for the Buckeyes in Atlanta. Seventeen members of the team are planning to compete in their respective Olympic trials for the chance to swim in Rio de Janeiro in August. read more


Mens Basketball Second half struggles give Ohio State 6244 loss to No


Ohio State redshirt senior guard Keyshawn Woods attempts a shot against Michigan State at the Breslin Center in East Lansing on Feb. 17. Photo: Casey Cascaldo | Photo EditorEAST LANSING, Mich — A sea of white hindered Ohio State while it tried to establish its offense. Each time the shot clock was under 10 seconds, the Michigan State student section counted down to one, seemingly leading to a rushed shot even when five seconds were left on the clock. C.J. Jackson, one of only two players on Ohio State’s roster that has played in East Lansing before, seemed unfazed. The senior guard, with five seconds left on the shot clock, put up a 3 from the top of the 3-point line as if time had expired. He sunk it, giving Ohio State the early 7-2 lead. But even as Ohio State showed spurts of offensive potential in the first half, inexperience and inconsistency reigned, and the sea of white rejoiced as the Buckeyes (16-9, 6-8 Big Ten) fell to No. 11 Michigan State (21-5, 12-3 Big Ten) 62-44 on Sunday. It was the least amount of points Ohio State has scored in a game this season. After shooting 40 percent from the field in the first half, making 3-of-6 from deep, Ohio State struggled with offensive consistency in the second, making 4-of-21 from the field and 1-of-9 from 3. The Buckeyes scored 13 points in the second half compared to Michigan State’s 37 and did not record a field goal in the final 7:40. Facing a defense that limits opponents to shoot 37.3 percent from the field, Ohio State head coach Chris Holtmann said struggling to score has been a challenge, but something he expected to see in this team. “It’s not like we didn’t expect that we were going to have trouble scoring this year,” Holtmann said. “We had an expectation that that was going to be something. We just have to keep taking good shots.” WIth the game tied at 39, Michigan State redshirt senior forward Kenny Goins sparked the Spartans’ second-half momentum, hitting a 3. But Jackson answered on the next possession with his second 3 in three tries. Jackson finished the game with eight points, making 1-of-6 opportunities from inside the 3-point line. But redshirt junior guard Kyle Ahrens answered with a 3 of his own, beginning a 10-0 Spartans run and putting a dagger through the hopes of the Buckeyes victory. “If they are all hype making shots, it’s tough to make shots when the crowd is going crazy and they are all hyped up on defense,” sophomore guard Musa Jallow said.In the second half, Michigan State made 12-of-26 attempts from the floor, shooting 42.9 percent from 3. As the crowd got behind the Michigan State offense, especially in the second half, Holtmann said it was hard to watch his team implode offensively. “It’s frustrating when you are struggling to score as much as you are struggling to score,” Holtmann said. “I think that is frustrating for guys because you tie so much of yourself to your offense.” In the first half, momentum favored the road team. The Ohio State offense came out hot, taking a 14-5 lead in the first seven minutes of the game. Sophomore forward Kaleb Wesson, in his second matchup with Michigan State junior forward and Gahanna, Ohio-native Nick Ward, scored six of the 14 points. Wesson finished the game with 12 points, the only Ohio State player with double-digit points, and nine rebounds.With Ward sidelined for the majority of the first half with a hand injury, Wesson said he feels like he battled in the post, but said he was unhappy with his six missed shots.But the runs continued in the first half. After redshirt junior Kyle Ahrens and Ward brought the Spartans back to within two, senior guard Matt McQuaid hit a corner 3 with Ohio State freshman forward Justin Ahrens draped over him, giving the Spartans its first lead of the day. With the Spartans holding onto a one-point lead heading into the final three minutes of the first half, Jallow hit a 3, igniting a 7-0 run and giving the Buckeyes a 31-25 halftime lead. This was the expectation for Jallow heading into the second half of play. “Just come back for another 20 minutes and play as hard as we did in the first half,” Jallow said. “When the game ended, we weren’t as good as we were in the first half.” Despite a six-point Ohio State lead heading into the second half, Michigan State began the half with a 7-1 run, tying the game at 32. However, offensive success came to a stand still for both the Spartans and the Buckeyes a the start of the half, combining to make two of 12 total shots, with Ohio State missing its first six. After the first half of play, Jallow felt this game was in the grasp of Ohio State. But after scoring 13 points in the second half, Jallow said this loss hurts. “It leaves a bad taste in your mouth because we knew this was a winnable game and we just didn’t do enough to pull it out in the second half,” Jallow said. Ohio State will travel home to take on Northwestern on Wednesday at the Schottenstein Center at 8:30 p.m. Updated at 4:32 p.m. with quotes from sophomore guard Musa Jallow, sophomore forward Kaleb Wesson and head coach Chris Holtmann. read more

Samsung said it doesn’t comment on rumors or speculation. Apple made the controversial move to remove the 3.5mm port when it released the iPhone 7 in 2016. Google, OnePlus, Huawei and others followed suit by removing the jack from their flagship phones, with Samsung being the most notable phone maker keeping it. Physical buttons appear to be slowly on the way out as more phone makers look to create sleeker designs.

Biologist suggests carbon monoxide as an energy source for microbes on Mars


first_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. In order for life to have existed on Mars (or if it still does in a place we have not found yet) it would have to have an energy source of some kind. Prior research has suggested such a source might be nitrogen, the same energy source for most plants here on Earth—a recent report by researchers studying data from Curiosity rover, describes nitrates found in the soil. In this new effort, King takes a different approach, he believes that carbon monoxide may hold the key to life on Mars.King took soil samples from three places here on Earth that have very dry climates and very salty soil, the Atacama desert in Chili, the Bonneville Salt Flats in Utah and a part of the big island in Hawaii. In studying the samples, he found that the soil did indeed pull carbon monoxide out of the air and held onto it. He suggests the same process could occur on Mars, as its atmosphere has more carbon monoxide in it than does ours. He goes further to suggest that the mysterious, recurring slope lineae—dark streaks that change color seasonally on Mars, might be due to carbon monoxide being pulled into the soil. He believes that carbon monoxide could represent the missing piece in the search for life on Mars: the energy source. As evidence of the possibility, he points out two microbes (Halorubrum str. BV1 and Alkalilimnicola ehrlichii MLHE-1) that live on Earth that use carbon monoxide as an energy source, one of which has also been shown able to tolerate salt concentrations that are similar to those found in Martian soil.Unfortunately, there is no mechanism for testing King’s ideas, neither of the rovers on Mars has the equipment needed for that kind of test. He will have to wait until 2021, when NASA plans to send a probe to the Red planet that is capable of detecting microbes in the soil. Explore further Valles Marineris, Mars. Credit: NASA (Phys.org)—Gary King, a biologist at Louisiana State University has put forth the idea that if life did exist on Mars, it very possibly could have survived by using carbon monoxide. In his paper published in Proceedings of the National Academy of Sciences, he discusses his study of microbes in soil samples collected here on Earth that are able to pull in carbon monoxide and why it might relate to life on Mars. Journal information: Proceedings of the National Academy of Sciencescenter_img More information: Carbon monoxide as a metabolic energy source for extremely halophilic microbes: Implications for microbial activity in Mars regolith, Gary M. King, PNAS, DOI: 10.1073/pnas.1424989112AbstractCarbon monoxide occurs at relatively high concentrations (≥800 parts per million) in Mars’ atmosphere, where it represents a potentially significant energy source that could fuel metabolism by a localized putative surface or near-surface microbiota. However, the plausibility of CO oxidation under conditions relevant for Mars in its past or at present has not been evaluated. Results from diverse terrestrial brines and saline soils provide the first documentation, to our knowledge, of active CO uptake at water potentials (−41 MPa to −117 MPa) that might occur in putative brines at recurrent slope lineae (RSL) on Mars. Results from two extremely halophilic isolates complement the field observations. Halorubrum str. BV1, isolated from the Bonneville Salt Flats, Utah (to our knowledge, the first documented extremely halophilic CO-oxidizing member of the Euryarchaeota), consumed CO in a salt-saturated medium with a water potential of −39.6 MPa; activity was reduced by only 28% relative to activity at its optimum water potential of −11 MPa. A proteobacterial isolate from hypersaline Mono Lake, California, Alkalilimnicola ehrlichii MLHE-1, also oxidized CO at low water potentials (−19 MPa), at temperatures within ranges reported for RSL, and under oxic, suboxic (0.2% oxygen), and anoxic conditions (oxygen-free with nitrate). MLHE-1 was unaffected by magnesium perchlorate or low atmospheric pressure (10 mbar). These results collectively establish the potential for microbial CO oxidation under conditions that might obtain at local scales (e.g., RSL) on contemporary Mars and at larger spatial scales earlier in Mars’ history.
