Measurements beneath an Antarctic ice shelf using an autonomous underwater vehicle

first_imgThe cavities beneath Antarctic ice shelves are among the least studied regions of the World Ocean, yet they are sites of globally important water mass transformations. Here we report results from a mission beneath Fimbul Ice Shelf of an autonomous underwater vehicle. The data reveal a spatially complex oceanographic environment, an ice base with widely varying roughness, and a cavity periodically exposed to water with a temperature significantly above the surface freezing point. The results of this, the briefest of glimpses of conditions in this extraordinary environment, are already reforming our view of the topographic and oceanographic conditions beneath ice shelves, holding out great promises for future missions from similar platforms.last_img

Anger over lost crown

first_imgRivalry between Jesus and Exeter Colleges has been revived after the crown was stolen off the bust of Jesus College founder Queen Elizabeth I in their College hall. The crown has not been returned, nor have the perpetrators been identified, but students have theorised that the thieves attend Exeter College.“The Exeter pranksters who have stolen the crown and who moved benches and threw towels around second quad in the last couple of weeks are being slowly honed in on through CCTV footage,” said a member of the JCR Health and Safety committee in an email to the JCR.However, the JCR President has denied that there is any CCTV footage and has emphasised that despite allegations, “there has been no evidence to suggest that a student from that college is to blame for the missing crown”.“We have a long-standing ‘banterous’ rivalry with Exeter,” explained JCR President Danielle Zigner.It is believed that the theft took place in connection with the “Turl Street Dash”, an annual tradition in which Exeter and Jesus students race around the streets of Oxford on bicycles and consume copious amounts of alcohol. The event was banned in 2010, but still took place this year.Students have speculated that the theft was premeditated, due to the assumed use of a screwdriver to remove the crown.“These rapscallions probably thought they were carrying out the crime of the century, but it was hardly the Great Train Robbery – they could have gone for anything but made off with a rather perfunctory piece of wood covered in gold-leaf,” said Jim Waterson, a finalist reading History at Jesus.“The crown was never my favourite anyway. If nothing else, ordering a replacement will allow us to modernise what is otherwise a rather dour piece of carving. Add a bit more bling to it, that sort of thing. Frankly, they can keep it.”Some Jesus students, however, are less forgiving. “Maybe they should be put in their place with a spot of retribution, a giant flaming Jesus crest burning on first quad perhaps,” suggested Declan Clowry.last_img read more

Wildcats outsmart, outplay Badgers

first_imgEVANSTON, Ill. –?With the Wisconsin football team leading the Big Ten in rushing defense, the Northwestern Wildcats did what any logical opponent would do?when faced with such a stiff test on the ground.They took to the air with reckless abandon.NU quarterback?and Big Ten Offensive Player of the Year candidate Mike Kafka attempted 40 passes against the Badgers beleaguered secondary, completing 26 for 326 yards and two touchdowns in a 33-31?UW loss?Saturday.The Badgers were blitzkrieged?early, giving up a touchdown on the first drive of the game and 27 points in the first half.The 248 yards passing and 33 points for the game were the most the Badgers have given up all season.As if Kafka wasn’t doing enough damage on his own, Northwestern found the end zone on a 38-yard wide receiver pass by Zeke Markshausen.“I think what it was is they knew a lot of the stuff that we were doing,” UW junior cornerback Niles Brinkley said. “They knew the concepts, they knew what coverages we were doing. … It was just them making a couple of big play that we didn’t make.”“It was crazy,” UW senior linebacker Jaevery McFadden added. “They was calling out names of our coverages out, right down to the number. It was crazy.”Only sacked once in 40 pass attempts, the UW pass rushers hit home several times throughout the game only to find the elusive quarterback scrambling.Although Kafka only finished with 17 yards on seven carries, the mobile senior often robbed Wisconsin of a drive-killing sack.Making pass rushers even more frustrated, the Wildcats utilize a quick hitting spread attack, usually getting rid of the ball on three step drops or short out routes.“Their offensive line did a great job,” UW sophomore defensive end J.J. Watt said. “And Kafka got the ball out real quick. We tried to get our hands up to bat some balls away, but we just didn’t do that. We put a lot of pressure on our D-backs because we didn’t get enough pressure on the quarterback.”“It’s extremely hard and it’s really frustrating as a defensive lineman, even if you win you may not get there.”Although Wisconsin scored a reasonable 14 points in the first half utilizing a balanced attack, UW took a note from Northwestern’s playbook and came out in the second half throwing.The Badgers threw 10 straight times with mixed success to open up the third quarter, moving the ball 51 yards but only coming away with a field goal. UW quarterback Scott Tolzien hit wide receiver Nick Toon for 25 yards and Garrett Graham for 14 yards on the drive, but the Badgers were stalled by two Isaac Anderson penalties.“We thought there were some opportunities down the field,” UW head coach Bret Bielema said. “Scotty [Tolzien] has been pretty clean with his reads and just based off what they had been able to do against us in the run game I thought we would loosen it up a bit.”Trailing by nine points entering the fourth quarter, the Badgers quickly cut the lead to two points when Tolzien hit Graham in the end zone for his second touchdown of the game.It was the last time the Wisconsin seniors would score in a Big Ten game, however, as the Badgers turned the ball over two times in their final three drives.“Probably danced with the devil too many times,” Bielema said of UW closing out late in games. “Even with 42 seconds, I guarantee there was not anyone on our sideline that didn’t think we would win that game.”Wisconsin’s last good chance came with 3:43 left in the game and the Badgers starting on their own 34-yard line.After picking up a first down on a five-yard interference call, UW went to sophomore running back John Clay on third-and-one. Having a decent game to that point with 100 yards on 23 carries, Clay fumbled the ball running into the back of senior tight end Mickey Turner.“It was me just trying to fight for extra yards,” Clay said. “I wasn’t holding the ball high and tight. … I tried to jump over [Mickey Turner] at the same time so I could get the first down, but I ran into him.”?????last_img read more

Interpreters To Assist Red Bank Police

first_imgMcConnell said his department contacted the officer who runs the program in that Texas city. Most of the volunteers were at the borough council meeting July 24 when the program was unveiled. Boris Kofman, a native of Belarus whose first language is Russian, said he had heard about the interpreter program through Triggiano. “This was something that we started working on back in January,” said councilwoman and police commissioner Kate Triggiano, who brought the idea to Red Bank. “I believe this might be the first program of its type in the state.” “They would never becalled out to a scene that’snot secured,” said police Lt.Juan Sardo, who oversees theprogram. “We won’t put themin jeopardy in that way. Theywill not be interviewing anysuspects in any crimes.” “So since I have that skill,I felt it’s my responsibility tohelp,” he said. “And he kind of helped us and guided us through how they set it up,” McConnell said. The police department has had a policy to first turn to one of its bilingual officers on duty to aid in translation; police also can use an interpreter service, called language line, via telephone. The volunteers would supplement that in any police-involved situation where authorities cannot communicate in English with members of the public. As with Kofman and Ortega, Red Bank is also Sardo’s second home. Originally from Venezuela, he came to the United States in 1979 when he was 6 years old, unable to speak English. Red Bank, where he grew up, was a different placethen. He remembered therewere a few Puerto Ricanfamilies at the time. That’sall changed, however. RED BANK – The Red Bank Police Department has a group of bilingual borough residents serving as volunteer interpreters to aid authorities when they deal with members of the public who do not speak English. Communicators on patrol, based on a similar program used by police in Houston, is made up of eight volunteers: seven Spanish speakers and one Russian speaker. They had to go through a background check and training and will be available to police on a round-the-clock basis. By Philip Sean Curran Red Bank police Chief Darren McConnell said he sees the volunteers also helping with community outreach, like with pedestrian bicycle safety. center_img “And like many of the residents that make up the demographics of Red Bank, I had to adapt to a new culture and language,” he said. Sardo, who joined the police department in 1997, recalled that he used to get calls from fellow officers, on his days off, to interpret for them. Today, the department has five Spanish-speaking officers, Sardo said. The borough said it is looking to grow the program to have volunteers who speak other languages or are fluentin American Sign Language. “I feel the need to helpmy community out,” saidCarla Ortega, a volunteeroriginally from Mexico.“If I’m needed, I feel like Ishould be able to help.” When he was still on the road as a police officer, McConnell took Spanish classes at Brookdale Community College to help him at work. “As the Spanish community grew in Red Bank, it became very difficult for us to communicate, even to get through minor calls like traffic stops and first aid calls and things like that, because we didn’t have many Spanish-speaking officers,” he said. “It was constantly an impediment.” Hispanics or Latinos make up 36.7 percent of the borough’s population of roughly 12,000, according to U.S. Census Bureau data. Houston, the city Red Bank modeled its program after, introduced its communicators on patrol program last July, said Jodi Silva, a spokeswoman for the Houston Police Department. In that department, volunteers must provide at least four hours of service per shift, be at least 18 years old and a U.S. citizen or legal permanent resident and be fluent in English and either Spanish, Vietnamese, Chinese, Arabic or Urdu/Hindi, among other criteria. Mayor Pasquale Menna, born in Italy, shared at the council meeting how he came to America as an immigrant who could not speak English. He said the interpreter program is one that the borough has never had. Police made clear that interpreters would not ride along with officers on patrol duty, interview criminal suspects or be put in harm’s way. “And many municipalities, I’m sure, have never even thought of doing it,” he said.last_img read more

Leicester v Chelsea: four key battles

first_imgCurrent leaders Chelsea travel to the reigning Premier League champions Leicester in Saturday’s evening kick-off. It was the scene of Jose Mourinho’s final game in charge, a 2-1 defeat in December 2015, but can the Blues return to winning ways? Here are four match-ups we think could be important.N’Golo Kante v Wilfred NdidiEmbed from Getty ImagesOne of the heroes of Leicester’s unlikely Premier League title win, Kante will make his playing return to the King Power Stadium, having been on the bench for the Blues’ League Cup tie earlier in the season. Interestingly, he has never been on the losing side in the three Leicester v Chelsea games. Wilfred Ndidi, signed from Genk, could be thrown straight in for his Leicester debut – though Foxes boss Claudio Ranieri has played down comparisons between the two.Gary Cahill v Jamie VardyEmbed from Getty ImagesLeicester will be boosted by the return of Vardy after suspension – although he only has five Premier League goals to his name, a far cry from last season’s 24. Cahill, who will again captain the Blues, has the challenge of stopping his England colleague from making his trademark runs into the channels.Eden Hazard v Danny SimpsonEmbed from Getty ImagesThe 3-4-3 formation, and arrival of Marcos Alonso, has freed up Hazard from any defensive duties and allowed him to concentrate solely on taking on his full-back. Next in his sights is former QPR man Simpson, whose performances this term have not lived up to the Foxes’ title-winning campaign – he was booked in four successive games in December.Marcos Alonso or Pedro v Marc AlbrightonEmbed from Getty ImagesThe left wing-back spot has been Alonso’s ever since the formation change post-Arsenal but there are suggestions the Spaniard may be rested to allow a leg injury to heal. The recalled Nathan Ake could play there but Pedro is more likely to be thrown in if Alonso is omitted. Former Aston Villa winger Albrighton set up six goals last season but is yet to create one this term.   Ads by Revcontent Trending Articles Urologists: Men, Forget the Blue Pill!

Separating Old Bones from Living Storytellers

first_img(Visited 46 times, 1 visits today)FacebookTwitterPinterestSave分享0 What happens when discrete bones are forced into a continuous narrative where they don’t fit? Answer: storytelling.Homo naledi fight: John Hawks just got on Michael Shermer’s case for storytelling. Hawks is a paleoanthropologist who has worked the past two years on the puzzling Homo naledi bones found in a South African cave (see 9/19/15). Shermer, president of the Skeptics Society who routinely bashes creationists and believers in intelligent design,  and extols science as the sole pathway to knowledge, apparently violated his own scientific beliefs. He wrote a piece for Scientific American alleging that the bones found deep in the cave were victims of violence, murder and cannibalism—a theory that fits with his favorite story about human origins.In his blog, Hawks accuses Shermer of going way beyond good scientific practice, force-fitting these bones into his prior narrative. Is it a case of “murdering the facts about Homo naledi” as his headline suggests? Shermer committed the same fallacy that Hawks found when asking 10-year-old schoolkids for ideas about how the bones got there. Each kid had an imaginary story, but none of them looked for actual evidence until Hawks told them there were no marks of violence on the bones.The schoolkids understood right away that the idea of murder and sacrifice don’t match the evidence that we have so far. Shermer preferred to speculate without evidence and publish an essay without fact-checking.It doesn’t seem like the work of a skeptic.Hawks continues by explaining the logic of science; it must respect evidence and be willing to reject a favorite narrative. Should Shermer step down as an exemplar of a “skeptic”?Shermer should think like a skeptic. Irrelevant details do not strengthen a story or make it more credible. Logic tells us that a story must be less probable than the least probable of its parts….I’m very sorry that he has misled so many Scientific American readers about the nature of evidence about Homo naledi and how we approach the science of human origins.Fitting dinosaur blood into 100 million years: Rachel Brazil has a colorful piece in Chemistry World about the struggle to fit soft tissue in dinosaur bones into long ages. Mary Schweitzer had shown in 2007 that the protein sequence from a T. rex closely matched that of a chicken. It stunned the secular scientific world; evolutionists claim all dinosaurs disappeared from the earth 65 million years ago.The evolutionary link between birds and dinosaurs was not unexpected, but the results were still met with deep scepticism – could proteins really survive this long?Although not the first report of ancient protein sequences, Schweitzer’s protein was 100 times older than anything else reported at that time.Brazil’s article is a tale of head-scratching by various scientists trying to explain (or explain away) Schweitzer’s evidence. It’s not like Schweitzer was ready to accept it herself.Schweitzer says she was stunned at what she saw. ‘I found what looked like blood cells inside the dinosaur bone, it was still very much bone. We discovered that if we demineralised the bone, we had material remaining which also flies in the face of how we thought fossils formed.’ The received wisdom is that organic matter degrades quickly with minerals completely filling the void over time.Remarkably, none of the scientists in the article are questioning the age of the dinosaur bones. That narrative is set in stone. All interpretations are focused on keeping the proteins and DNA old. When Schweitzer found proteins in a hadrosaur thought to be 80 million years ago, nobody acquiesced on the age.But that work did not silence her critics. ‘I think a large part of the scientific community is still undecided,’ explains Buckley. He accepts that the likely survival limit for proteins is older than his 3.5-million-year-old high arctic camel. ‘I wouldn’t be overly surprised if it was twice as long, but from a few million years to pushing on 80 million years is a huge jump.’ Collins agrees that this is what current publications suggest, but tantalisingly claims his lab is working on some exciting new ideas as to how proteins may survive longer than this, which he thinks could be game-changing.Another scientist was convinced he was looking at dinosaur collagen in Schweitzer’s sample—and red blood cells, too—but he still didn’t waver on the age. Brazil then ups the ante by mentioning that dinosaur DNA may still exist. “Meanwhile, Schweitzer is waiting for more excavated samples to test and it remains to be seen if further evidence or new theories on protein preservation can sway her sceptics.” In her thinking, they only need to be swayed on the issue of whether it’s real dinosaur material. Nobody, not even Schweitzer, is questioning the age. From there, Brazil ends with irrelevant remarks about whether old dinosaur bones can tell us about climate change.Turkey farmers: Researchers from Stockholm University are claiming that Europeans descended from farmers in Anatolia, modern Turkey. It’s interesting that DNA from the samples is heavily degraded after just 8,000 years, the alleged date. These scientists are showing restraint, knowing that more data would be needed to interpret the origin of farming. “Our results stress the importance Anatolia has had on Europe’s prehistory. But to fully understand how the agricultural development proceeded we need to dive deeper down into material from the Levant.”Bigfoot evolution: This giant ape is no myth. Gigantopithecus (giant ape) is well-known from fossil representatives. But can the bones support PhysOrg‘s headline, “Giant ape Gigantopithecus went extinct 100,000 years ago due to its inability to adapt”? The story is that their food source ran out, but nobody watched what they ate, or how flexible they were at changing diet if needed. All we know is that they don’t live in China or Thailand today. That didn’t stop researchers from telling us all about what happened, even though living apes contradict the story:Bocherens and his colleagues work on the assumption that Gigantopithecus’s size, in connection with its restriction to one habitat type, doomed the giant apes. “Relatives of the giant ape, such as the recent orangutan, have been able to survive despite their specialization on a certain habitat. However, orangutans have a slow metabolism and are able to survive on limited food. Due to its size, Gigantopithecus presumably depended on a large amount of food. When during the Pleistocene era more and more forested areas turned into savanna landscapes, there was simply an insufficient food supply for the giant ape,” concludes the scientist from Tübingen.Volcano wok: One of the most ridiculous stories in recent science reporting is that volcanoes made humans intelligent. Live Science says that right in the headline: “Volcanoes Sparked an Explosion in Human Intelligence, Researcher Argues.” Tia Ghose, always hip to celebrate an evolutionary story, gives it good press:Vast lava flows may have provided humans with access to heat and fire for cooking their food millions of years ago, one researcher has proposed.That, in turn, would have enabled the evolution of human intelligence, Michael Medler, a geographer at Western Washington University, said at the annual meeting of the American Geophysical Union earlier this month.At one point, Ghose says Medler tests the idea, but then says the idea is difficult to test. If volcanoes create intelligence, why didn’t all the other animals in the area learn to cook and grow their brains? Medler qualified his story a little, admitting that “other environmental factors” likely played a big role, too. Maybe it was climate change.Push the mammal age back: Evolutionists don’t mind surprises as long as they can hold onto their narrative. Another evolutionary activist reporter on Live Science, Charles Q. Choi, folds a surprise into the narrative of mammal evolution. The headline “Ancient Mouse-Size Creature Uproots Mammal Family Tree” seems to falsify Darwinism, but not really. It actually “clears up a long-standing mystery,” he comforts his listeners. It just means “that mammals originated more than 30 million years more recently than previously suggested,” he suggests, so the suggestion of millions of years can stay put in the Darwin Suggestion Box.Evolve with me: The origin of flight has to be among the largest challenges to slow-and-gradual evolution there is. In Current Biology, though, Zhong Zhou and crew have turned up another fossil bird in China’s Jehol fossil beds. It has characteristic tail feathers indicating it was a strong flyer. The problem is, unrelated birds also have good tails.The hypothesis that rectricial bulbs and a plough-shaped pygostyle are co-evolved receives further support via the recent discovery of a rectricial fan in the basal pygostylian Sapeornis. Although proportionately larger, the sapeornithiform pygostyle is morphologically very similar to that of ornithuromorphs….This supports an alternative scenario in which rectricial bulbs and pygostyle reduction evolved independently in sapeornithiforms, pengornithids, and ornithuromorphs….Notably, such a high degree of homoplasy [convergent evolution] is not uncharacteristic of early avian evolution.So instead of similarities falsifying the evolutionary tree of birds, it confirms it. The story lives on!When is a hypothesis not a hypothesis? When it’s just a story. Don’t you get frustrated at the storytelling of the Darwinians? Evidence doesn’t matter. John Hawks rightly rebuked Michael Shermer on his unskeptical adherence to his favorite narrative, but Hawks remains an evolutionist himself. That’s one narrative that is non-negotiable among those with D-Merit badges in Big Science Establishment New Year’s Parties. They dare not lose their badges and get kicked out into the cold.last_img read more
