The process is complex, and takes about 72 hours.The sperm are “morphologically normal” (normal-looking), the researchers said. It is not known whether the tiny cells are up to the job of creating babies.The next step, the team said, is to try and give life to rats with rat sperm created using the method.“We must see if the baby rats are normal, whether they are able to reproduce,” project member Philippe Durand told journalists in Lyon.Then there will be a battery of tests with the lab-manufactured human sperm, to compare it to ordinary sperm, and finally clinical trials.The work has not yet been validated through publication in a peer-reviewed science journal.But the team said in a statement their work “opens the way for therapeutic avenues that have been eagerly awaited by clinicians for many years.”“From a testicular biopsy in these infertile men, the scientists will be able to obtain spermatozoa in vitro,” said the statement.However, Nathalie Rives, an infertility expert from Rouen in northern France, cautioned: “We are not there yet”.“Before this technique can find any practical application, it must be proven to work with (cells) from the testes of prepubescent boys and men who have trouble generating sperm,” she told AFP.In August 2011, scientists in Kyoto said they had successfully coaxed sperm cells from mouse embryonic stem cells.

Nedd wants son to focus on batting ahead of 2020 U-19 World Cup-Proud of Junior Cricketer-of-the-Year AwardSeptember 18, 2020 | By admin | No Comments | Filed in: fofabvlic.
FORMER Guyana off-spinner Garvin Nedd said he’s pleased with his son Ashmead’s achievements this year, following his team’s maiden Regional Super50 title win and being named the 2019 Guyana Cricket Board (GCB) junior cricketer of the year.Need, who will return home for the holidays after being on Windies U-19 duties in the Tri-Series versus England and Sri Lanka, has endured a whirlwind past few weeks. His West Indies Emerging Players (WIEP) upset the entire Regional Super50 roster to win their first ever major title a few weekends back.Nedd then ended with 7 wickets, including a 5-Fer from five games played in the Tri-Series despite the Windies missing out on the final spot. At last Wednesday’s GCB Awards ceremony, Nedd bagged the highest Junior award: Cricketer-of-the-Year and, due to his absence, his father received the award on his behalf.Nedd Snr told Chronicle Sport on Saturday that he was overly impressed with the strides Ashmead has made in recent times, adding that he was privileged to accept the award on behalf of his son.Garvin and Ashmead Nedd“As a parent and coach, it’s good to see the improvements that he has been making to his cricket. We did some remodeling on his bowling action from the last World Cup, so I think its showing now because he’s bowling much better”.The 18-year-old spinner, who has a few hundreds and a double hundreds in domestic cricket, made his batting skills a crucial part of his arsenal whether it was for the WIEP or the WI U-19 team, which he helped save on a few occasions with some rock-solid innings.His father said with the World Cup just around the corner, batting is one of the areas he wants Ashmead to work harder on. “One of my concerns for him is the batting. I think he’s a much better batsman and if he continues to work on his stroke-play and assessing the conditions when batting, I think he is well on his way to becoming a genuine bowling all-rounder.” Nedd Snr. Stated.The West Indies U-19 players will now enjoy the Christmas holiday season before getting back into full game-mode as the 2020 U-19 World Cup bowls off from January 17 to February 9 in South Africa.
Cody Bellinger homer gives Dodgers their first walkoff win of season Though he is reluctant to sing Betts’ praises as a hitting coach too loudly, Barnes has said his new teammate has been instrumental in getting him on the right path at the plate.“Mookie’s great. I can’t say enough about him and what he’s doing in the clubhouse,” Barnes said. “He’s helped me tremendously. I don’t know if he wants it all out there. He kind of wants it under the radar. But he’s helped me swing-wise. He really has. Just talking about the game, talking hitting. He’s helped me in the cage. He’s been in there with me, watched me swing.“That just shows you what kind of teammate he is for him to take time out of his day to help someone else. He’s been great.”Barnes said Betts “reached out to me which was pretty cool.”“He just thought he could help and he really has,” Barnes said. How Dodgers pitcher Ross Stripling topped the baseball podcast empire Dodgers hit seven home runs, sweep Colorado Rockies Newsroom GuidelinesNews TipsContact UsReport an Error Fire danger is on Dave Roberts’ mind as Dodgers head to San Francisco Dodgers manager Dave Roberts calls Barnes’ offensive reclamation project a collaboration among Barnes, Betts and hitting coaches Brant Brown and Robert Van Scoyoc.“Mookie just kind of did some things to free up his mind, give him some clarity, give him some cues, some keys mechanically,” Roberts said. “It has landed with Austin. Just using the big part of the field, staying in the strike zone and some things mechanically that they’ve talked through. It’s paid big dividends up to this point.”Barnes said part of the breakthrough has been mechanical. But being in a better place mentally has also been a big factor in rediscovering the skill set that made him a .298 hitter in the minor leagues and a .289 hitter during his first full season in the big leagues three years ago.“It’s nice going up there, feeling like you’re going to hit the ball hard,” he said. “I think they kind of play off each other a little bit (the mental side and swing mechanics). I made a couple adjustments mechanics-wise. When you’re hitting the ball on the barrel, that shoots your confidence up at the plate. They kind of work hand in hand.”GONSOLIN SENT DOWNRight-hander Tony Gonsolin pitched a career-high six innings in Tuesday’s win, extending his scoreless streak over three starts this season to 14 2/3. But that wasn’t enough to change the Dodgers’ plans.After throwing those six innings, Gonsolin would have been unavailable for a few days. With the Dodgers currently using a six-man starting rotation, his turn wouldn’t come up again until Monday, an off day. So Gonsolin was sent back to the Dodgers’ alternate training site Wednesday and lefty reliever Victor Gonzalez was recalled.Roberts acknowledged that Gonsolin’s performance is “very much” forcing the Dodgers to reconsider how they might use him going forward — but not yet.“I think the way he pitched — performance certainly does matter,” Roberts said. “I don’t think that right now we have to be set in the rotation to finish the season or even think about the postseason. But Tony has done everything he can do. That’s a good thing for the Dodgers. Our message to Tony was just to continue to keep that edge, keep pitching well and be ready. Certainly what he’s done here in three starts is not lost on anyone.”ALSOAfter throwing three innings in a simulated game Tuesday, left-hander Alex Wood (shoulder inflammation) is scheduled to throw a four-inning sim game on Monday. …The Dodgers had planned to move their secondary training site from USC to the minor-league stadium in Rancho Cucamonga when students returned to campus. With no plans for students to attend classes in the near future, however, the Dodgers will keep their training site at USC for the duration of the season. …Right-hander Josh Sborz, catcher Rocky Gale and utilityman Zach McKinstry traveled with the Dodgers as the taxi squad for the two-game series in Seattle.Related Articles Dodgers’ Max Muncy trying to work his way out of slow start Austin Barnes has heard a lot of voices over the past two seasons as he tried to rediscover his identity as an offensive player.The ones inside his head were probably the worst.“I feel good mentally up there right now. I feel free up there mentally,” the Dodgers catcher said Tuesday. “I was a little clouded before. It’s hard to hit like that, that’s for sure.”The freedom Barnes has found recently has resulted in a seven-game hitting streak (through Tuesday) during which he is 12 for 24 with five multi-hit games. And Mookie Betts gets credit for an assist.
