The increased transmissibility is believed to arise from a change in the virus’s spike protein that can allow the virus to more easily enter cells. These and other studies on the new variant were released before peer review to share their findings quickly.Additionally, there is some evidence that patients infected with the new B.1.1.7 variant may have a higher viral load. That means they may expel more virus-containing particles when they breathe, talk, or sneeze.As professors who study fluid dynamics and aerosols, we investigate how airborne particles carrying viruses spread. There is still a lot that scientists and doctors don’t know about the coronavirus and its mutations, but there are some clear strategies people can use to protect themselves.Airborne particles are still the biggest problemThe SARS-CoV-2 variants are believed to spread primarily through the air rather than on surfaces.When someone with the coronavirus in their respiratory tract coughs, talks, sings or even just breathes, infectious respiratory droplets can be expelled into the air. These droplets are tiny, predominantly in the range of 1-100 micrometers. For comparison, a human hair is about 70 micrometers in diameter.The larger droplets fall to the ground quickly, rarely traveling farther than 6 feet from the source. The bigger problem for disease transmission is the tiniest droplets – those less than 10 micrometers in diameter – which can remain suspended in the air as aerosols for hours at a time.How effective are different types of masks? UNSW/Thorax.With people possibly having more virus in their bodies and the virus being more infectious, everyone should take extra care and precautions. Wearing face masks and social distancing are essential.Spaces and activities that were previously deemed “safe,” such as some indoor work environments, may present an elevated infection risk as the variant spreads.The concentration of aerosol particles is usually highest right next to the individual emitting the particles and decreases with distance from the source. However, in indoor environments, aerosol concentration levels can quickly build up, similar to how cigarette smoke accumulates within enclosed spaces. This is particularly problematic in spaces that have poor ventilation.With the new variant, aerosol concentration levels that might not have previously posed a risk could now lead to infection.What can you do to stay safe?1) Pay attention to the type of face mask you use, and how it fits.Most off-the-shelf face coverings are not 100% effective at preventing droplet emission. With the new variant spreading more easily and likely infectious at lower concentrations, it’s important to select coverings with materials that are most effective at stopping droplet spread.When available, N95 and surgical masks consistently perform the best. Otherwise, face coverings that use multiple layers of material are preferable. Ideally, the material should be a tight weave. High thread count cotton sheets are an example. Proper fit is also crucial, as gaps around the nose and mouth can decrease the effectiveness by 50%.2) Follow social distancing guidelines.While the current social distancing guidelines are not perfect – 6 feet isn’t always enough – they do offer a useful starting point. Because aerosol concentration levels and infectivity are highest in the space immediately surrounding anyone with the virus, increasing physical distancing can help reduce risk. Remember that people are infectious before they start showing symptoms, and they may never show symptoms, so don’t count on seeing signs of illness.3) Think carefully about the environment when entering an enclosed area, both the ventilation and how people interact.Limiting the size of gatherings helps reduce the potential for exposure. Controlling indoor environments in other ways can also be a highly effective strategy for reducing risk. This includes increasing ventilation rates to bring in the fresh air and filtering existing air to dilute aerosol concentrations.On a personal level, it is helpful to pay attention to the types of interactions that are taking place. For example, many individuals shouting can create a higher risk than one individual speaking. In all cases, it’s important to minimize the amount of time spent indoors with others.The CDC has warned that B.1.1.7 could become the dominant SARS-CoV-2 variant in the U.S. by March. Other fast-spreading variants have also been found in Brazil and South Africa. Increased vigilance and complying with health guidelines should continue to be of the highest priority.This article is republished from The Conversation under a Creative Commons license.

Umphrey’s McGee continue to impress on their West Coast March run, stopping at the Crystal Ballroom in Portland, OR for a fiery performance. The group wasted no time getting to work, opening with “Dump City” and raging through the first set with versions of “In The Black” and “Go To Hell.” One of the first highlights from the show came during “Nemo,” when guitarists Brendan Bayliss and Jake Cinninger joined keyboardist Joel Cummins for an all-out keyboard jam. What fun!Another big bust-out was a cover performance of Ween’s “Transdermal Celebration,” which the group debuted during the Godboner set with Gene Ween at Summer Camp Music Festival (watch the full set here). Since we don’t have footage from last night’s second-ever performance of the Ween song, we’ll have to settle for the debut version:The rest of the show continued to impress, with jams like “Triple Wide > Speak Up” and a “1348 > Made 2 Measure > 1348” medley.

Press Association Phil Neville is set to become the latest recruit to David Moyes’ coaching team at Manchester United. Although there has been no official confirmation, it is understood Neville was at the renamed Aon training complex on Thursday morning for the first full day of training since Moyes was installed as Sir Alex Ferguson’s replacement. It would represent yet another switch from Everton following the earlier appointments of Steve Round, Chris Woods and Jimmy Lumsden. However, in Neville’s case it also brings a vast amount of experience of life at United. Neville made 386 appearances in 11 seasons as a first-team player with the Red Devils. During that time he won six Premier League titles, three FA Cups and the Champions League before leaving to join Everton in 2005, where he overcame some initial scepticism to become a crowd favourite. Neville confirmed his intention to retire at the end of last season, although new Everton boss Roberto Martinez had claimed he intended to speak with the 36-year-old about a coaching role. However, a return to the club he supported as a boy was always likely to prove attractive and it is no surprise Moyes has opted to build on the close working relationship he developed with Neville during their time together at Goodison Park. Neville has never made any secret of his desire to push forward with a coaching career and this summer was part of Stuart Pearce’s backroom team at the European Under-21 Championship. In addition to bringing a sense of continuity following the departures of not only Ferguson but also his assistants Mike Phelan, Eric Steele and Rene Meulensteen, Neville will provide a useful link between the dressing room and the manager. There has still been no word on Wayne Rooney’s status though, with the formal talks that had been anticipated on Wednesday apparently put on hold. Rooney has returned for pre-season in good condition though, which, by his own admission, has not always been the case. And despite the massive upheaval at Old Trafford this summer, that has also seen the exit of chief executive David Gill, the atmosphere is said to be upbeat ahead of the new campaign, which begins next Wednesday when United head off on their five-match summer tour of the Far East and Australia.
First place in the AFC South will be on the line when the Colts (6-4) travel to play the Texans (6-4) on “Thursday Night Football” (8:20 p.m. ET, Fox, Amazon Prime Video, NFL Network). Indianapolis leads the division because of beating Houston at home earlier. Houston right now would make the playoffs as the AFC No. 6 seed.Should the Colts win, they would go from the No. 4 behind the Chiefs to No. 3. Should the Colts lose, they would drop to No. 7 behind the Raiders, to whom they lost. Should the Texans win, they would go from No. 6 to No. 3. Should the Texans lose, they would drop to No. 7, too, hoping the Raiders lose to the Jets on Sunday to get back to No. 6.Here’s everything to know about betting on Colts vs. Texans in Week 12, including updated odds, trends and our expert’s prediction for “Thursday Night Football.”MORE: Get the latest NFL odds & betting advice at Sportsbook ReviewColts vs. Texans odds for ‘Thursday Night Football’Spread: Texans by 3.5Point total: 45Odds: Colts -103, Texans -107The Texans are basically a little more than home-field favorites here after getting crushed on the road by the Ravens. The spread has gone up to 4 points in their favor for some sportsbooks. The Colts are coming off a convincing home win over the Jaguars.Colts vs. Texans all-time seriesThe Colts have dominated the series since it began in 2002 when the Texans entered the NFL, going 28-8. The Colts have won three straight and five of six, including the teams’ wild-card playoff meeting last January, 21-7. The Texans beat the Colts in overtime in Indianapolis last September.Three trends to know— 57 percent of spread bettors are going with the Texans. 57 percent of moneyline bettors are going with the Colts.— With Deshaun Watson and Jacoby Brissett as the quarterbacks, despite injury concerns on both offenses, 55 percent of bettors like the game to go over the point total.— The Texans are 2-5 against the Colts over the past three seasons. Only 3 of the past 8 games between the teams have gone over.Three things to watchWill Fuller return?The Texans need some wide receiver pop downfield to help DeAndre Hopkins and Watson. Will Fuller was close to coming back from his hamstring injury against the Ravens and is a game-time decision to see his first action since Week 7. Should he go, it would be a huge needed boost to Watson against the Colts’ secondary.No Mack — but likely yes HiltonThe Colts will be without Marlon Mack, who fractured his hand against the Jaguars. That means they turn to a committee of Jonathan Williams, Jordan Wilkins and Nyheim Hines for the eary-down and receiving load. Williams was great against the Jaguars, but the Texans are a better run defense. But Colts wide reciever T.Y. HIlton, a noted Houston killer, looks like he’s returning from his calf injury. The Colts will need to throw more often and effectively with Brissett to win.Frank Reich vs. Bill O’BrienReich’s aggressive coaching staff has gotten the better of O’Brien’s early in their sideline rivalry. The Colts play a lot of close games are are good at winning battles of attrition, despite recent losses to the Dolphins and Steelers. O’Brien needs to have his team push the right buttons late to avoid a mild upset. Stat that mattersThe Texans are the No. 13 run defense in the NFL, allowing on average 102 yards per game, but they give up 4.7 yards per carry. The Colts rank No. 9, at 96.8 yards per game at 4.3 yards per carry. This game will likely be won through the air by either Watson or Brissett. The Colts are No. 11 there, while the the Texans are No. 29.Colts vs. Texans predictionWatson had a rough outing in Baltimore but will rebound at home to lift his team in a crucial game. The Colts’ offense is missing its top power back Mack, and although Brissett will grind and deliver some big pass plays to Hilton and others to keep the Colts in it, Watson will deliver the game-winning drive late.Texans 24, Colts 20

The hire-and-fire policy of owner Roman Abramovich means managers have a limited shelf life and players have previously exploited the policy.This is not the same group as the one that defied Andre Villas-Boas or masterminded a Champions League win under Roberto Di Matteo, when the senior players were said to be more influential than the interim manager.But the incident suggested there could be a leadership vacuum at Stamford Bridge.Sarri replaced Antonio Conte in July and got off to a flying start, with Chelsea unbeaten for the first 18 competitive games.But recent results have included the 6-0 mauling at City, a 4-0 loss at Bournemouth and a 2-0 defeat by Manchester United in the FA Cup at Stamford Bridge.After the Spurs game, Chelsea have a run of what appear to be winnable fixtures before away matches against Liverpool and Manchester United in April.But the question is whether Sarri still has authority in the dressing room and whether he will be given the time to turn things around. Chelsea keeper Kepa ArrizabalagaLondon, United Kingdom | AFP | Kepa Arrizabalaga’s extraordinary refusal to be substituted by Maurizio Sarri in Sunday’s League Cup final heaps the pressure on the beleaguered Chelsea boss as he desperately seeks consistency. The Spaniard twice required treatment late in extra-time against Manchester City at Wembley, with the match heading for penalties, so the Italian boss planned for his substitution.Willy Caballero, who saved three penalties for City in their 2016 League Cup final win, was readied to go on, but Kepa declined to leave the pitch — sparking confusion and angering Sarri.Even after the bizarre incident, the world’s most expensive goalkeeper had the chance to be a hero.He saved Leroy Sane’s penalty in the shootout, but could have done better with Sergio Aguero’s effort that slipped under his body as Pep Guardiola’s side retained the trophy with a 4-3 shootout win after a goalless draw.Victory at Wembley might have bought Sarri time, particularly coming so soon after a 6-0 humbling by the same opponents in the Premier League.But instead the 60-year-old Italian, who is yet to win a trophy in his managerial career, must prepare his players to host high-flying Tottenham in the Premier League on Wednesday, knowing he cannot afford to slip further behind the top four.Sarri, Kepa and David Luiz, the closest player to Kepa throughout the incident, were “on message” after the match at Wembley, all insisting it was a misunderstanding, not insubordination.“The coach has the power over the group. He has our respect,” Luiz said. “For me, there is not a problem here for that. We all believe in his philosophy, we all believe in the way he wants us to play.”But former Chelsea skipper John Terry said the former Napoli coach was in a difficult situation, with the incident coming after weeks of speculation over his future and concerns over his style of play, dubbed “Sarri-ball”.“It leaves Sarri in a tough place,” he told Sky Sports. “I’m surprised he didn’t force him to come off.”Ex-Chelsea striker Chris Sutton described the scenes as “mutiny at Chelsea”.
