Boss Arsene Wenger says Mesut Ozil will return to the Arsenal squad when they host Chelsea on Sunday, but Alexis Sanchez may not be risked.Ozil has fully recovered from the foot injury that kept him out of last weekend’s 0-0 draw at Stoke and will definitely be involved.Sanchez is also close to full fitness, having been sidelined since November, but Wenger admitted it would be a gamble to play him against the Blues.He said: “The doubt is that he has been out for a long time and [there is] the risk of a setback if you try to go too early.“To be clear on all the tests is one thing, training is another thing, and after that the intensity of a big game which you can never repeat in a training session.“I am cautious with him because we cannot afford a setback with him. A setback would mean a very long period out so we don’t want to take this gamble.”Wenger also confirmed Francis Coquelin returned to full training on Thursday, with Danny Welbeck doing likewise next week. Tomas Rosicky is also ruled out of the Chelsea match.See also:Costa and Hazard passed fit for Arsenal clashArsenal v Chelsea: match preview, team news, facts and figuresFollow West London Sport on TwitterFind us on Facebook
There’s never been a surprise that a good astrobiologist hasn’t been able to spin into an evolutionary tale.For a recent example, see the post “How old are the first planets?” on NASA’s Astrobiology Magazine or the reprint on PhysOrg. In this article, every surprise or anomaly became fodder for Keith Cooper’s imagination. Here are a few of the unexpected observations in the article that Cooper worked into the grand scenario of cosmic evolution and the origin of life:1. Rocky planets: The Kepler spacecraft has found rocky worlds around metal-poor stars that were previously thought to lack ingredients for planets. Solution: “one way of looking at terrestrial planets is to see them as failed gas giant cores.” Even more exciting, it means (contrary to earlier beliefs) that rocky planets – and maybe life – may abound around metal-poor stars! “If Earth-sized planets do not require stars with high abundances of heavy elements, then that has huge implications, expanding the possible abodes for life throughout both space and time.” Cooper even jumped from his imaginary solution to the conclusion that it implies the “Galactic Habitable Zone” might be wider than thought.2. Fermi Paradox: Point #1 raises the ghost of the Fermi Paradox: if there are so many rocky worlds with life, how come none have visited the earth by now? (Their inhabitants, presumably, have had billions of years to evolve advanced technology.) Solution: Dodge the question with a distracting discussion of how and when gas giants can evolve around low-metal stars.3. Heavy metal galaxies: The evolutionary scenario predicted heavy elements would gradually increase over time; early galaxies, therefore, should be depleted in heavy elements. “Twelve billion years ago the chemistry of galaxies should have been fairly primitive,” Cooper confessed, yet a distant galaxy matched the sun in heavy elements. Solution: “The best explanation so far is that a starburst – a ferociously rapid bout of star formation – within the inner regions of the galaxy has blown the heavy elements into the galactic outlands.” In philosophy of science, this is known as a post hoc rationalization.4. Planet billiards: Gas giants should wreak havoc with rocky planets, sending them careening out of a star’s planetary system as the gas giants migrate inward, but Kepler has found rocky planets interspersed between gas giants. Solution: claim that “what difficulties gas giants can cause for habitable planets, they don’t necessarily have to be a show-stopper“. But if they are, it only takes one to stop the show.5. Impoverished gas giants: Gas giants were thought to require an abundance of heavy elements to form cores for accretion of gas, but some have been found around metal-poor stars. Solution: “it must have formed very early in the history of the Universe,” or, “Why gas giants have been able to form around these heavy-metal deficient stars is unknown, perhaps hinting at an alternative process for gas planet formation.”These and other anomalies, failed expectations and surprises are dealt with accordingly by Cooper and his astronomer interviewees. Given a lively imagination, no problem is too damning to falsify biological evolution, planetary evolution, stellar evolution, galactic evolution and cosmic evolution. Here’s how Cooper roused his readers’ imaginations in a sweeping set of glittering generalities (after dodging the 4th point above about planet billiards, and while dodging example #2 about the Fermi Paradox):Regardless, one thing is becoming clear: that sufficient raw materials for building terrestrial planets were available very soon after the Big Bang, raising the possibility that there could be life in the Universe far older than we. Perhaps they reside around long-lived red dwarf stars, or have moved on from their home system after their star expired. Or, perhaps, we really are the first, which means that if life has happened just once throughout the entire history of the Universe, our existence must be a fluke and our planet very, very special indeed.Such a conclusion would allow for any eventuality: even the uniqueness of life on earth would fit an evolutionary scenario.In another article on PhysOrg, planetary theorist Alan Boss came up with a novel way to get refractory compounds into comets, where they were previously thought not to exist: cook them near the sun, then send them out to the fringes by special delivery. “Their meandering trips back and forth could help explain the different compositions of their rims.” This, along with a discussion of calcium-aluminum inclusions (CAIs) in meteorites, was touted as solving two solar system puzzles at one blow. “It’s nice to solve two problems at once,” said Boss. “But there are still many more puzzles about meteorites for us to work on.” Incidentally, his theory of disk instability for the formation of gas giants runs counter to the core accretion model Keith Cooper assumed in his article.Astronomer Stephen Weinberg once defined an expert as “a person who avoids the small errors while sweeping on to the grand fallacy.” In this case, Cooper and his Darwin Party experts don’t avoid any errors: they actually use the large errors to sweep on to the grand fallacy. We might also recall that an expert (ex-spurt) used to be a spurt, but is now just a drip. Oh, their empirical observations are doing fine: the Kepler spacecraft, the spectrometers, the equations – all built using intelligent design – are pulling the scientific load. But the scenario, the play, the imaginary story they repeat in spite of the observations – these are what illustrate the skill of evolutionist gumbies to twist any falsification into a celebration of their gnostic powers. Historical note: Johannes Kepler, for whom the planet-hunting spacecraft was named, was a creationist. (Visited 14 times, 1 visits today)FacebookTwitterPinterestSave分享0
Descendants of freedom fighter Laxmi Indira Panda on Saturday staged a protest at Jeypore in Koraput district, demanding expeditious police investigation to trace her grandson, Babula Panda, who went missing on April 16 at the railway station here. Babula’s parents, Surendra Panda and Sujata Panda, were among the descendants of freedom fighters felicitated by Prime Minister Narendra Modi at the Raj Bhavan here. Babula had accompanied his parents to the function. Laxmi Indira Panda had joined Netaji Subhas Chandra Bose’s Indian National Army in the Rani Jhansi Regiment when she was only 14 years old, and fought against the British for the country’s Independence. Separated at stationJust an hour before Babula and his parents were to board the Hirakhand Express from Bhubaneswar to return to Jeypore, the three got separated at the railway station. While Babula’s father Surendra Panda reached Jeypore a day later, his mother Sujata Panda boarded a wrong train and landed in Balasore, from where she was rescued. But Babula could not be traced.Subsequently, Chief Minister Naveen Patnaik directed the police to find Babula, but the police had made no headway till Saturday. “It is duty of the government to find our son,” said Ms. Panda.
Thirteen students of the Central University of Haryana (CUH) in Mahendergarh were suspended on Thursday for allegedly creating “hindrance in the smooth functioning of academic and administrative functioning of the university”. The suspended students, including 11 BTech students, and others have been on strike since the past 10 days against lack of infrastructure and staff in the School of Engineering and Technology.Misbehaviour alleged The suspension came a few hours after the agitating students — who were protesting against alleged misbehaviour by security guards with female students on Wednesday night — prevented Vice-Chancellor R.C. Kuhad from leaving the premises in his car. They claimed the security guards used force on Wednesday to disperse students, including women, who were holding a peaceful protest outside the university’s Academic Block. They added that the guards also tore posters, prompting hundreds of students to hold a protest all night. The agitating students alleged that varsity officials misbehaved with them on Thursday and locked the building from inside to prevent them from entering the premises to drink water and relieve themselves.‘Baseless claims’Dismissed as “baseless” the allegations of misbehaviour by the guards, CUH spokesperson Shailender Kumar accused the students of manhandling the V-C. He claimed CUH had agreed to meet their demands in a time-bound manner and a notice in this regard was already circulated on April 15. Lack of facilitiesThe students are on strike since April 9, alleging that two years after the School of Engineering and Technology was established in 2016, it still lacks minimum facilities like laboratories, building and regular staff. The School offers BTech in four disciplines. However, a student of BTech (electrical engineering) said promises made by the administration were hollow. “We want a letter signed by the V-C himself with a promise to meet all our demands in a time-bound manner. We believed the verbal assurances of the V-C last August but nothing happened. How can we believe the administration that laboratories will be ready in three months when construction of building is yet to start?” said the student. CUH Finance Officer Sanjeev Kumar said the university’s notice to meet the demands of students in a time-bound manner had the approval of the V-C and was signed by the Registrar. “It seems that some people are instigating the students. The students seemed satisfied after a marathon meeting with the V-C on Wednesday but were instigated into continuing the protest. They are coming up with new demands every other day,” said Mr. Kumar.He added that approval of the All-India Council for Technical Education (AICTE) was not required for BTech courses as the university was autonomous body and received grants from the University Grants Commission.
The police in Assam have arrested more alleged members of the extremist group Hizb-ul-Mujahideen (HM), believed to have been planning to launch a disruptive “start-up” in the State.On Monday, the police in central Assam’s Nagaon and adjoining Hojai districts, arrested three men — Riyazuddin Bhuyan, Joynal Ahmed and Baharul Islam. Sleuths, police said, had been keeping a watch on the trio after inputs that they had assisted HM operative Qamar-uz-Zaman during his visit to the State in August.Qamar, hailing from Jamunamukh in the Hojai district, was arrested last week from Kanpur in Uttar Pradesh. Four of his associates, including one from Meghalaya, had been arrested till Sunday.Cashing inThe police said the HM had sent Qamar to Assam to radicalise Muslim youth, possibly to cash in on a feeling of victimisation because of the exclusion of many from the draft National Register of Citizens (NRC). “They had plans to launch a start-up in Hojai district. We had kept tabs on the suspects but did not have concrete evidence on their connection with the HM. The arrests were made after collecting technical evidence,” Ankur Jain, Hojai district Superintendent of Police, said.He did not specify the nature of the start-up the HM or Qamar’s associates had been planning to set up.Tracing contactsAssam’s Director General of Police (DGP) Kuladhar Saikia, who is monitoring the investigation, said police traced the people Qamar had contacted or moved around with during his “recruitment trip” in August.Qamar had avoided his home in Jamunamukh but stayed in the house of one Shahnawaz Alam arrested last week. Police said Qamar had also used Riyazuddin’s motorcycle to move around during his stay.Qamar is believed to have been radicalised in Kashmir, where he had gone on some business a few years ago. Police came to know about his joining HM from his photo, in fatigues and holding an AK-47 rifle, uploaded on social media.Assam had a few short-lived Islamist groups that allegedly worked for Pakistan’s Inter-Services Intelligence (ISI) and Bangladesh’s Directorate General of Forces Intelligence (DGFI) to help militant outfits such as the United Liberation Front of Asom (ULFA) in the 1990s.
