LONDON (AP):Less than 24 hours before the global football spotlight falls on Leicester in their bid to win the top tier for the first time, Newcastle came out best in the scrapping at the other end of the English Premier League yesterday.The Magpies moved out of the drop zone for the first time since February after midfielder Andros Townsend’s superb free kick gave Newcastle a 1-0 win over Crystal Palace.”The victory means a lot. It gives us momentum, confidence and a connection with the fans,” said Newcastle manager Rafa Benitez.Sunderland again had to rely on its top scorer Jermain Defoe, with the striker grabbing a last-minute equaliser from the penalty spot in a 1-1 draw against Stoke, who took the lead through striker Marko Arnautovic.”Where would we be without Jermain Defoe?” said Sunderland manager Sam Allardyce before answering his own question. “Relegated probably.”Despite drawing, Sunderland dropped into the relegation zone, one point behind 17th-place Newcastle and one point ahead of 19th-place Norwich, who lost 1-0 at Arsenal after Danny Welbeck’s goal in the 59th.”The last thing you can do down in the dogfight is feel sorry for yourselves,” said Norwich manager Alex Neil. “We didn’t get what we deserved.”Both Sunderland and Norwich have three games left while Newcastle have two.At the top, leaders Leicester can win the title by beating Manchester United today.

The spokesman of the government of Sierra Leone, Mr. Abdulai Bayraytay, said his government is awaiting the scientific report from the committee responsible for the fight against the Ebola pandemic in that country, before a determination is made on the success of the three-day lockdown.In a telephone interview with a Liberian journalist yesterday, Mr. Bayraytay disclosed that the lockdown, which started last Friday, was welcomed by the majority and that some are even suggesting that it continues.Mr. Bayraytay was, however, quick to point out that any decision by government to carry out a monthly three-day lockdown as suggested by many residents in the country, will depend on the outcome of the scientific report from field workers used during the lockdown.About 30,000 fieldworkers were trained and deployed throughout the country of over six million people.Mr. Bayraytay disclosed that the amount of US$1.6 Million was used during the lockdown, with the amount of US$700,000.00 from the coffers of the Government of Sierra Leone, while the rest came from friends of the country and NGOs.During the lockdown, Mr. Bayraytay said over150 people willingly reported to the nearest holding or isolation centre to be tested.The curfew in Sierra Leone came into force on Friday morning, with most of the country’s six million inhabitants confined to their homes.Around 30,000 medical volunteers travelled to affected neighborhoods to find patients and distribute soap.Deputy Chief Medical Officer Sarian Kamara said authorities had managed to discover 22 new cases of the virus during the curfew.”Had they not been discovered, they would have greatly increased transmission,” he said.He also said between 60 and 70 Ebola victims were buried during the three days of the lockdown, and that the authorities had managed to discover 22 new cases of the virus during the curfew.The three-day curfew is the most aggressive measure yet taken against the virus by a West African country.Sierra Leone has been one of the countries worst affected by the outbreak, with more than 550 victims among the 2,600 deaths so far recorded.Like Sierra Leone, Liberia is currently battling with the Ebola pandemic, and its citizens and residents are presently observing a 90-day state of emergency declared in August by President Ellen Johnson-Sirleaf.Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)
1 Simon Grayson was a big hit at Elland Road during his time as manager Simon Grayson’s return to Elland Road turned sour as Preston keeper Jordan Pickford was sent off after half an hour and Leeds banked a 1-0 win for their third victory in four games.Pickford’s early departure meant an unexpected debut for Preston’s fourth-choice keeper Matt Hudson who was beaten by a headed own goal from Alan Browne just after the break.Grayson received a warm welcome from Leeds supporters who remembered his achievement in guiding the club out of Sky Bet League One during his spell in charge.Leeds keeper Marco Silvestri, outstanding throughout, made three top quality saves in the opening 10 minutes as Grayson’s men went all-out attack.First the Italian keeper pushed Paul Gallagher’s curling free-kick round the near post. Then Joe Garner played Will Keane through the middle and Silvestri was quick to leave his line and deny the England Under-21 forward a scoring chance.A minute later Silvestri was in action again, diving full length to his left to turn Garner’s 25-yard shot behind for a corner.After their hesitant start, Leeds forced a series of corners which were well defended but they should have opened the scoring in the 23rd minute.Liam Bridcutt was allowed to make a long run down the middle and Chris Wood timed his run perfectly to receive his pass. However, the totally unmarked striker shot straight at Pickford.With 30 minutes gone Preston suffered a controversial blow when Pickford was shown the red card. A long ball out of defence found Wood, and Pickford collided with him just outside the box.The keeper endured a long lecture from referee Gavin Ward before being sent to the dressing room amid strong protests from his team-mates.Hudson left the bench and former Liverpool midfielder John Welsh was sacrificed as Preston faced the rest of the match with 10 men.When the free-kick was eventually taken, Giuseppe Bellusci lifted it just over the bar.Hudson’s first task was to gather a corner in the congested goalmouth and the youngster, who has been selected in England’s elite goalkeeping camp, proved equal to the task.However, the second half was less than 30 seconds old when Leeds winger Stuart Dallas crossed from the left and Preston midfielder Browne headed into his own net, giving Hudson no chance.Browne was substituted in the 55th minute, enabling Neil Kilkenny to make an appearance against his old club.Silvestri made two fine saves from Kilkenny and Marnick Vermijl’s angled header as Steve Evans’ side won.

Roses have a special pigment molecule, a particular form of anthocyanin, responsible for all the rich red-to-blue shades in the petals that delight gardeners and attract pollinating insects. This molecule is different from the pigments in every other flowering plant; it is glycosylated at two positions instead of one.2 A single enzyme does the job at both points. Without the glycosylation reaction at both ends, the molecule is unstable and cannot be soluble in water in the vacuoles of the cells in which it operates. A team of Japanese scientists investigated how this double-glycosylation reaction system might have evolved. They could find no intermediate. Reporting in Nature,1 they said that while other flowers use derivatives from a singly-glycosylated form, “this is evolutionarily precluded in roses by their different glycosylation pattern, which may be unique to members of the Rosaceae” (emphasis added in all quotes). They also stated with puzzlement,It is a mystery why this particular glycosyltransferase evolved independently in roses. The novelty of the RhGT1 enzyme therefore lies not only in its ability to catalyse glycosylation at two different sites on the anthocyanidin molecule but also in its apparent absence from other species.They prepared a phylogenetic tree based on this type of pigment-preparing enzyme family, but it ended up with the rose family on a branch all by itself.1Ogata et al., “Plant biochemistry: Anthocyanin biosynthesis in roses,” Nature, 435, 757-758 (9 June 2005) | doi: 10.1038/nature435757a.2Glycosylation replaces an OH (hydroxyl) group with a glucoside. This is performed by an enzyme called a glycosyltransferase, in the case of roses, RhGT1.Here is a small gap, but a gap nonetheless; no evidence for the evolution of this complex molecule and the enzyme that knows how to operate it – just an unconfirmed prediction from evolutionary theory. Surprised? Question: was evolutionary theory of any value in this investigation?(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0
