Evidence for cryptic diversity in the “pan-Antarctic” springtail Friesea antarctica and the description of two new species.

first_imgThe invertebrate terrestrial fauna of Antarctica is being investigated with increasing interest to discover how life interacts with the extreme polar environment and how millions of years of evolution have shaped their biodiversity. Classical taxonomic approaches, complemented by molecular tools, are improving our understanding of the systematic relationships of some species, changing the nomenclature of taxa and challenging the taxonomic status of others. The springtail Friesea grisea has previously been described as the only species with a “pan‐Antarctic” distribution. However, recent genetic comparisons have pointed to another scenario. The latest morphologicalstudy has confined F. grisea to the sub‐Antarctic island of South Georgia, from which it was originally described, and resurrected F. antarctica as a congeneric species occurring on the continental mainland. Molecular data demonstrate that populations of this taxon, ostensibly occurring across Maritime and Continental Antarctica, as well as on some offshore islands, are evolutionarily isolated and divergent and cannot be included within a single species. The presentstudy, combining morphological with molecular data, attempts to validate this hypothesis and challenges the taxonomic status of F. antarctica, suggesting that two additional new species, described here as Friesea gretae sp. nov. and Friesea propria sp. nov., are present in ContinentalAntarctica.last_img read more

Redknapp: Rio leads by example

first_imgRio Ferdinand does not need the captain’s armband to spearhead QPR’s Barclays Premier League survival fight, according to Harry Redknapp. Hull boss Steve Bruce is determined not to set the bar too high for his side this season but is targeting an improvement on last term’s 16th-place finish and a run to the FA Cup final and Europe. He said: “We’ve done fantastically well over the last couple of years. We’ve never been here (in the Premier League) for two years so that is the challenge. “In my experience the second season is always the most difficult because the expectation has risen a bit. “We’ve brought in four or five players to strengthen the squad. The man thing is for the club to stay in the Premier League and that’s what we’ve got to do. “Everybody expects us to be better than we were last year and if we can manage it that would great.” Bruce expects a tough opener at Loftus Road against Redknapp’s men who will be aiming to copy the Tigers’ own survival masterplan in their first season back in the top flight. And despite predictions the London outfit could struggle, the Hull boss is particularly wary of the threat posed by striker Loic Remy, provided the Rs are able to keep hold of him in the remainder of the transfer window. “Harry has managed to hang onto Loic Remy which I believe is key for them,” added Bruce. “He’s a very good striker and no disrespect to QPR, but he is arguably the best player in the bottom half of the division with the talents he’s got.” Clint Hill remains Rangers’ official club skipper, but Ferdinand is favourite to lead the side on the field in the former Crystal Palace defender’s absence. The pairing of Ferdinand and Steven Caulker in QPR’s new-look back three could limit Hill’s starting chances this term. Redknapp said he will review the on-field captaincy on a weekly basis any time Hill does not secure a starting berth. Press Association “I haven’t really looked at a vice-captain, I’m not one that gets that bothered about it,” said Redknapp ahead of Saturday’s league opener against Hull. “Making Rio captain, would it make him any different? Not really. He would talk and boss people just the same. “I haven’t spoken to anyone, I haven’t spoken to Clint, but we’ll probably take it as it comes each week, depending on who’s in the team. “It can change. Rio’s had a fantastic impact, he’s just class around the place. “He just oozes class, he’s a top player and you can’t replace that. He’s been there and done it all, he’s won everything there is to win, so we’re just delighted to have him here. “He’ll definitely be a big influence on Steven (Caulker), I think he’ll be a big influence on all the players. “They look at how he trains, how he works: every day he comes in, works hard, lives his life right, he’s always at the front of what we’re doing in training and he’s in great condition. “He’s a model professional.” last_img read more

All By Myself

first_imgWhat would you do if you had a last minute overnight layover in Las Vegas? For most of us it would be an excuse to party on the Strip until sunrise. Richard Dunn however, got a little more creative. He gave up a night of partying in favour of a night in with his iPhone, filming a music video to Celine Dion’s “All By Myself.”So how does one “all by himself” alone in an airport manage to capture a spectacular video almost as good as Celines? Richard explains his approach. “I had a person behind a ticket counter give me a roll of luggage tape before she left. I then used a wheelchair that had a tall pole on the back of it and taped my iPhone to that. Then I would put it on the moving walkway for a dolly shot,” Dunn wrote on his Vimeo page. “I also used the extended handle on my computer bag and taped the iPhone to my handle. I would tuck different stuff under the bag to get the right angle. For the escalator shot I had to sprint up the steps after I got my shot so the computer bag didn’t hit the top and fall back down. Quite fun!”You can see the brilliant video (below) of Dunn lip-syncing to Celine’s hit while wandering through the vacant airport. We hope this is not a one hit wonder for him!last_img read more

Bafana in Mandela Challenge draw

first_img14 November 2011A stunning free kick by Katlego Mphela saw Bafana Bafana come from behind to earn a 1-all draw with Africa’s top ranked team, Cote D’Ivoire, in the annual Nelson Mandela Challenge in Port Elizabeth on Saturday.The result means South Africa remains undefeated in five matches against the Ivorians, with one win and four draws.Pitso Mosimane’s men had fallen behind on an own goal by Siboniso Gaxa, but Mphela’s second-half free kick left goalkeeper Boubacar Barry rooted to the spot.It was the best possible reply the Mamelodi Sundowns’ striker could muster towards a section of the crowd that had booed him throughout the first half.‘Mphela is the best we have’Coach Mosimane was less than impressed by the boo boys and offered his backing for the striker at the post-match press conference, saying: “If there is anyone better than Mphela, I want that name. All the coaches and journalists must give me that name. We need that name. It’s a fact, Mphela is the best we have.”Immediately after the game, in an on-field interview, he had expressed his disappointment in the number of opportunities his charges had spurned.Overall, Mosimane was positive about his side’s performance. “We did well and showed that we can play well against the best, but we are not there yet, not convincing enough,” he said.“At the end, it was a credible performance and I think we redeemed ourselves to give the country what it deserves.”SatisfiedThe Ivorians’ coach, Francois Zahoui, said that he too was on the whole satisfied with his team’s showing, although he admitted they have plenty to work on before the African Cup of Nations finals, which kick off on 21 January 2012.Playing in new jerseys, South Africa started the game off fairly well, but Gervinho was giving Tsepo Masilela a tough time, and matters became worse when Masilela suffered an injury which forced him from the field after 26 minutes.He was replaced by Siboniso Gaxa, which meant replacing a natural left-footer with a right-footed player on the left. Interestingly, in the first half, Siphiwe Tshabalala, a left-footer, was used wide on the right. It didn’t work, but when he returned to the left in the second stanza, he shone.The Ivorians’ fired the first shot of the contest when winger Seydou Doumbia forced an early save out of Bafana net-minder Moeneeb Josephs.Good chanceMphela had a good chance to put Bafana in front a quarter-of-an-hour into the game after Reneilwe Letsholonyane played him in with a neat ball, but Mphela’s weak left-footed effort was easily dealt with by the goalkeeper.The visitors then appeared to have a clear-cut penalty disallowed after Gervinho was brought down in the box. The Ivorians were angered by the non-call, so much so that captain Didier Zokora earned himself a caution because of his protesting.With 30 minutes played, Barry pulled off a good save of a Morgan Gould header, which came from a Tshabalala free kick.Own goalSix minutes later the deadlock was broken when Gaxa headed into his own net after some miscommunication in defence, which gave the Ivory Coast a 1-0 advantage.Goalie Josephs was called on to make a save with his feet from Doumbia with five minutes remaining, but the final chance of the half went the way of South Africa when Kagisho Dikgacoi set up Mphela, but he again failed to find a meaningful finish.Stunning precisionSeven minutes into the second stanza, Bafana levelled matters when Mphela took responsibility for a free kick on the left hand side of the field and with stunning precision found the bottom right hand corner of Barry’s net with his shot.Buoyed by the goal, Bafana upped the pressure on Cote D’Ivoire and Barry needed some sharp reflexes to prevent Siaka Tiene netting an own goal.On the hour-mark, the Elephants almost took the lead again, but Josephs did well to keep out efforts by Doumbia and Gradel Max.The level of play dropped a little as the game drew towards its conclusion, but with the end nearing Anele Ngcongca found Mphela with a cross from the right. The striker’s header was stopped by Barry, and Ngconga’s effort to slot the rebound was snuffed out.Would you like to use this article in your publication or on your website?

Passive House in the Woods Goes Energy-Positive

first_img RELATED ARTICLES Passive House in the (Wisconsin) WoodsPassive House in the Woods Opens Its DoorsBlog Review: Tim EianWisconsin Electric Cooperative Jolts Passivhaus Owner The house is equipped with a solar hot water system, a 4.7-kW photovoltaic system, and a ground-loop system and liquid-to-air heat exchanger designed to pre-warm, pre-cool, and dehumidify the ventilation air as needed.Getting to positiveBased on PHPP calculations, Eian explained, as much as 80% of the heat load over the course of the year has been covered by passive solar gain.“While we predicted this with our energy models,” Eian wrote in the TE Studio blog, “we found and learned through monitoring that some equipment and appliances use more energy than assumed. On the flip side, user behavior plays a major role as well and can effectively lower energy consumption over the predicted model.”Eian also pointed out to GBA that more performance tracking will be needed to create an accurate picture of monitored usage. TE Studio summarized the monitoring data for 2011 in a report to the building’s owner, Gary Konkol, a general-practice physician, but at this point that information isn’t being released to the public.So monitoring will continue and, Eian adds, “no changes to the building’s systems or performance are scheduled. On whole, the building performs as predicted and the owner is very excited about it.” As the clock wound down on 2011, marking a full year of monitoring for Passive House in the Woods, in frosty Hudson, Wisconsin, it became clear that the building’s design, construction, and renewable-energy systems had combined to deliver net-zero-energy performance, and then some.Tim Eian, of Minneapolis-based TE Studio, designed the home to meet the Passivhvaus standard and teamed up with Morr Construction Services, of Shoreview, Minnesota, to turn the plans into reality. The 1,940-sq.-ft. home was certified by the Passive House Institute U.S. in October, and Eian recently reported on the TE Studio blog that it had produced more energy than it used in 2011.The home’s above-grade walls are built from 11-in.-thick insulated concrete forms (ICFs) clad with an exterior-insulation and finish system (EIFS) that brought the overall R-value of the walls to 70. The slab, which sits on 12 in. of extruded polystyrene, is designed to deliver R-60 thermal resistance, and the flat roof, with an average of 14 in. of polyisocyanurate insulation, is rated at R-95.last_img read more

Delhi University’s high cut-offs make admission difficult for boys

first_imgHigh percentages for B. Com (Honours) in DU’s recent cut-off list have left the male applicants particularly disappointed.With the first cut-off percentage for this discipline having crossed the mark of absurdity on Tuesday, there was a general air of disappointment among commerce students.”I got 93 per cent in my Class XII boards and I was sure I would get a seat in a good college for B. Com ( Honours) or Economics ( Honours). But that was before the first list came out,” Ankita Tyagi, an aspiring student, said.The cut-off for commerce has been the highest among all programmes on offer.Male students with an aggregate between 90 per cent and 94 per cent are now left with limited options.Colleges available to these students include the Atma Ram Sanatan Dharam College, College of Vocational Studies, Shaheed Bhagat Singh College and Motilal Nehru College.A large number of all-girls colleges in DU means that boys applying for the same courses have even fewer opportunities to go to the institution of their choice.”While I will get Delhi College of Arts and Commerce with a 94 per cent score, girls have the option of getting a better college such as IP College,” Rohan Singh, who had come to Hindu College on Wednesday to check its cut- off list, said.Although DU’s first cut- offs did exclude hundreds from taking admission in many sought after colleges, there were happy faces on the North Campus too.Aditi Verma, who got 96.25 in Class XII boards, was ecstatic as she made the cut for SRCC. “I had heard colleges were going to increase their cut- off marks this year so, even after getting a good percentage, I had my fingers crossed,” she said.advertisementNeha Singh, a humanities student who scored 94.3 per cent in boards, said the high cut- offs were expected because the “results this year were very good”. Keen to get admission in Political Science (Honours) in Hindu College, she was very happy as she had made the cut-off.For more news on India, click here.For more news on Business, click here.For more news on Movies, click here.For more news on Sports, click here.last_img read more

Can Ajay Jayaram overcome constant injuries? ‘It is a mental challenge’

first_imgIt has been a tough year for Ajay Jayaram battling recurring injuries and seeing his compatriots make their name on the world stage from the sidelines.Earlier this year, Jayaram reached his career-high ranking of world No.13 but soon after his rise and growth was hampered by a knee injury.Jayaram played in the World Championships with the injury trouble and ended up aggravating it. It has been a story of a series of injuries ever since.”I think it’s (injury) probably the biggest battle an athlete faces. I have been through a shoulder surgery before and, yes it’s been hard. This year has been exceptionally tough because it hasn’t been a black and white injury where I could decisively tell that I would be back in so much time. It was pretty hard to decide whether to play or not and it kept recurring as well, and that’s a real mental challenge,” Jayaram said in an exclusive chat with IndiaToday.in.Jayaram will be playing for a new team, North Eastern Warriors, this season in the Premier Badminton League (PBL), which is scheduled to start from December 23.Welcome to #NEWarriors. #PBLAuction @PBLIndiaLive pic.twitter.com/4zbAXYl1UP- NE Warriors (@NEShuttlers) October 9, 2017Jayaram was one of the best performers in the previous edition of the tournament and he is looking forward to putting up good performances once more to get himself back on track.”Somehow I’ve done well in PBL for the past 2-3 years. It’s fun to play with so much of people supporting you and coming to watch and I’ve enjoyed that entire thing. It kind of set me up for a good year (PBL 2) but sadly, I had to step down. I probably reached my career best and then faced the injury, so yeah. PBL is different from the regular circuit to some extent, I would say. I think if I manage to do well this season again, I can take a lot going forward,” Jayaram shared.advertisementWhile badminton is essentially an individual sport, PBL’s format enables these individuals to come together as a team and perform in a unit. In PBL, two teams take on each other in different categories like men’s singles, women’s singles, men’s doubles and mixed doubles and the points won in each category translate to a total score.Jayaram feels that though badminton remains an individual sport even in PBL, the team factor adds a zing to the whole competition and with teams cheering and backing you, it brings a different kind of inspiration and motivation.”It’s tricky because I would say that it’s still an individual sport. At the end of the day, you’re on court alone. But yeah, certain elements come with leagues like this where there’s a certain inspiration and motivating factor that really originates from the team bonding. There are elements but yeah it’s not entirely a team sport like football, where you need to gel with your teammates but still, I’d say it has elements of both.”There’s definitely an element of team motivation that factors in and I think, it’s very important even when you’re off-court and cheering for the teammates, you need to feel the vibe and energy. I think it really translates onto the court and to the person playing,” Jayaram told.Jayaram has reached the finals of the PBL consecutively in the past two years with two different teams (Delhi Dashers and Mumbai Rockets) and will look to make it a hat-trick of finals, leading his new team to the last stage of the tournament and make their debut season a memorable one.”I feel I have been lucky to reach the finals twice in a row with two great teams but I don’t take it as an added pressure on my performance. As always, I will try to perform to the best of my abilities and look to get the desired result for the team.”At the age of 30, Jayaram has now accepted the injuries that incessantly trouble him and instead focusses all his energy into the recovery.”I think, at the end of the day it’s about accepting certain things and that your body probably has taken a toll over the years. I have been focussing a lot more on recovering in the last couple of months, with physio treatments and making sure that I am completely prepared before every session and even after the session, recovering in all possible forms.”So, yes, it’s all about doing the best you can with whatever you have. You can’t keep cribbing about how it would’ve been had I not been injured and all, it’s part of an athlete’s journey and it’s all about dealing with it,” Jayaram noted.advertisementHe conceded that his training sessions differed as he was recovering and he attempted to manage his body well. He shared that going for shots was a struggle when he began his recovery due to mental block but it eased off with time.”The intensity and duration of the training sessions have reduced a bit. I normally train for 5-6 hours in 3 sessions and now I have reduced it to two, limiting myself to one on court session and one in the gym and running. I’ve tried to manage the best I can.”Generally, in the initial part of the injury, yes, one kind of faces a certain kind of mental block. But I think it’s all about getting through it, when you practice enough and once you’re confident on court in practice, it kindly wears off. It’s just a matter of time when that thing is overcome,” Jayaram concluded.last_img read more

Google celebrates 30 years of World Wide Web with a doodle

first_imgNew Delhi: Google celebrated 30 years of the World Wide Web with a colourful doodle on Tuesday. On this day in 1989, Sir Tim Berners-Lee, then a 33-year-old software engineer, submitted “Information Management: A Proposal” to his boss, which then came to be known as the World Wide Web as we know it today. “Initially, Berners-Lee envisioned it as ‘a large hypertext database with typed links’, named ‘Mesh’, to help his colleagues at CERN (a large nuclear physics laboratory in Switzerland) share information amongst multiple computers,” the search engine giant said in a blogpost. Also Read – Spotify rolls out Siri support, new Apple TV app Initially terming the proposal as “vague but exciting”, his boss encouraged Berner-Lee to “develop the humble flowchart into a working model, writing the HTML language, the HTTP application, and WorldWideWeb.app – the first Web browser and page editor”. By 1991, the external Web servers were up and running. Not to be confused with the internet, which is a huge network of computers connected together, the World Wide Web is an online application built upon innovations like HTML language, URL addresses, and hypertext transfer protocol, or HTTP. Also Read – New Instagram tool to help users spot phishing emails The web made technology into something that linked information together and made it accessible to everyone. “Your browser uses the internet to access the world wide web,” the blogpost explained. Starting from a proposal, the Web over the last 30 years has become a decentralized community, with nearly 2 billion websites online, founded on principles of universality, consensus, and bottom-up design.last_img read more
