Surprising Things Science Didn’t Know

first_img(Visited 59 times, 1 visits today)FacebookTwitterPinterestSave分享0 Scientists presume to speak with confidence about the origin of the universe and billions of years, but have been clueless about some everyday things close to home in the present.Mystery of the whistling teakettle:  PhysOrg reported that two Cambridge researchers have finally figured out how the teakettle produces a whistle.  “Researchers have finally worked out where the noise that makes kettles whistle actually comes from – a problem which has puzzled scientists for more than 100 years.”  Science Now wrote wittily about this, saying:For centuries, physicists have made their living by illuminating the secrets of our universe, from gravity to electricity to black holes. But among the search for Higgs bosons and the endless unspooling of string theories, there remained a particularly glaring mystery: Why does a teakettle whistle? “Oh that,” they said, standing at their stoves in between bouts of programming supercomputers. “Vibrations. Or something.” Now, we are happy to report, human intellect has at last triumphed over the dark shadow of ignorance and solved the conundrum lurking within one of our lowest-tech kitchen appliances…. And having solved another mystery of our vast but perhaps ultimately knowable universe, they smile and sip their tea.Discovery in the knee:  One would think after centuries of dissections and surgeries that the human knee is pretty well understood.  Not so; a “new” ligament has been discovered, reported the BBC News, named the anterolateral ligament.  It looks pretty obvious from the photo in Medical Xpress.  It’s important, too: it helps protect the knee when we twist or change direction.  Without it, the knee can suddenly give way.  A surgeon outside the study group remarked, “If you look back through history there has been a veiled understanding that something is going on on that side of the knee but this work finally gives us a better understanding.”Manhattan’s Grand Canyon:  Just 100 miles off Manhattan’s shores, a canyon rivaling the Grand Canyon plunges off the continental shelf into the deep sea.  Live Science says that Hudson Canyon is “a city in its own right, brimming with an extraordinary universe of life.”  So close to the busiest city on earth, it’s a gigantic feature biologists are only beginning to inventory, inhabited by animals small and great – from plankton to sperm whales, corals, squid, sea anemones, swordfish and much more, some of which are shown in an embedded video clip.  Hudson is just one of 15 such large submarine canyons along the east coast south of Cape Cod that the article says are remnants of ancient rivers that flowed off the continental shelf when sea level was lower.  Beyond the canyon is a series of prominent seamounts – dormant volcanoes rising thousands of feet from the seafloor.Those large canyons appear to be Flood remnants.  It’s hard to imagine ordinary rivers carving so many canyons that huge so close to one another.  Only if massive, unprecedented waters were draining off the continents would these remnant geological features be expected.Once science can figure out the teakettle, maybe it can move on to more grandiose ambitions like explaining why toast tends to land buttered side down.  Those problems at least are tractable.  Evolution is so full of variables, unknowns and degrees of freedom, its error bars surpass the axes.  That’s why any story fits between the error bars.  Let’s tell the Darwin Party to stop wasting our time with speculations about the unobservable past, and help the guy with the bum knee get through physical therapy.  He needs compassionate evidence-based knowledge of knee structure and function, not storytelling about how vacant ecospace led to the Cambrian explosion.last_img read more

10 months agoLiverpool legend Nicol: FSG to blame for FA Cup exit

first_imgAbout the authorPaul VegasShare the loveHave your say Liverpool legend Nicol: FSG to blame for FA Cup exitby Paul Vegas10 months agoSend to a friendShare the loveLiverpool legend Steve Nicol has slammed the club’s owners over their FA Cup exit at Wolves on Monday night.With Liverpool suffering Champions League, Europa League, League Cup and FA Cup Final defeats since FSG bought the club in 2010, it leaves the 2012 League Cup as both the Reds’ last trophy and only silverware of the American group’s Anfield stewardship.Nicol told ESPN FC: “For the big teams, particularly in England, it’s about the Premier League and Champions League.“Let’s not forget, that Kenny Dalglish got the sack after winning silverware at Liverpool, and losing the FA Cup final. So, work that one out.“So the owners want the Premier League and the Champions League clearly.“If Jurgen Klopp doesn’t want to sacrifice anybody in order to win the Premier League or the Champions League then he’s going to do what he did the other night and play what, three first team [players]?”Nicol accused his former side of disregarding the competition as they suffered their fourth-successive third or fourth round exit under Klopp.“Well, yes, because of the era I played in – yes I do (have a problem with domestic cups not being taken seriously).“All the other trophies meant something, the Carabao Cup used to mean a lot.“The FA Cup was absolutely huge, it for me was basically the player’s tournament.“But times have changed, and now it’s about Premier League and Champions League.” last_img read more

My life revolves around sport, so I don’t like to rest and I enjoy working all the time. In addition, when you have a game every three days, the last thing we can think about is to rest.

Syrian family caught in fire thought they would be safe in Canada

first_imgHALIFAX — At 30 years of age, Syrian refugee Kawthar Barho had seen her share of suffering and death before she came to Canada with her family.Together with her husband Ebraheim and their children, she fled the northern city of Raqqa, where Islamic State militants had established their provisional capital.“This is one of the most devastated cities in Syria,” says Imam Abdallah Yousri of the Ummah Mosque in Halifax. “It has been totally destroyed.”The Barhos arrived in Nova Scotia in September 2017, and thought they would be safe in Canada.Early Tuesday, fire raced through their new home in Halifax, killing seven children and burning Ebraheim Barho so badly that he remained in critical condition in hospital on Wednesday.Halifax’s Muslim community is now preparing for a funeral at the mosque for the couple’s children: Ahmad, 14; Rola, 12; Mohamad, 9; Ola, 8; Hala, 3; Rana, 2 and Abdullah, who was born in Canada on Nov. 9.“They thought that they were fleeing from the war over there to be safe here, and they ended up as if they were back there,” says Yousri, who has been offering support to Kawthar Barho since the early morning fire.“It is a tragedy for her, for us, for everybody.”Yousri says the young woman remains in a state of shock.“She is in terrible condition right now,” says Yoursi. “She keeps thinking this is the time for her to breastfeed (Abdullah). She keeps calling him.”The family moved to the Halifax neighbourhood of Spryfield only five months ago, having left the more rural community of Elmsdale, N.S. — but the transition wasn’t working out, despite a warm welcome from neighbours.The large family was among 1,795 Syrian refugees who have come to Nova Scotia in recent years.However, Yousri says it would appear that only the Barhos came from Raqqa.“They don’t even have friends here,” he says. “They feel lonely here, without any relatives, without any friends.”Spryfield resident Nicole Snook, whose home is just down the street from where the Barhos lived, said she and other neighbours reached out to the family, but the language barrier got in the way.“We baked them cookies at Christmas, gave a gift for the baby and talked to the kids on the street,” she said as her toddler fussed in her arms.“The kids were very active. They were always out on the street playing.”Photos from Facebook show the Barhos enjoying a fall trip to a local farm. A picture of three-year-old Hala shows her smiling as she hugs a small pumpkin. A photograph of 12-year-old Rola show her holding a Student of the Month certificate from the Riverside Education Centre in Milford, N.S.Snook says she was particularly taken with the oldest girl, Rola, whose mastery of English and outgoing demeanour made her a pleasure to talk to.“I was blown away by her — she was beautiful,” says Snook.“You could tell she was an exceptional human being. She had an openness and a real social nature … She wasn’t bold, it was more like a healthy assertiveness … She struck me as someone who would go far in life with such an indomitable spirit.”Snook recalled how polite the children were when they showed up at her doorstep on Halloween.“I was struck by their willingness and openness to engage in conversation,” Snook says, adding that their kindness and poise seemed remarkable for children who had endured a vicious civil war that has claimed more than 400,000 lives since 2011.At first, the family lived in Elmsdale, where they received support from the Hants East Assisting Refugees Team, the Nova Scotia group that sponsored their refugee claim. The Barhos lived there for a year, then moved to Spryfield to be closer to refugee support services, such as English-language training.But the children missed their old school and the friends they had made there, so the plan was to move back to Elmsdale next week.The Hants East group said in a Facebook post: “For the past year and a half, the children have been able to enjoy life as kids should be able to: going to school, riding bicycles, swimming, having friends, running in the yard, celebrating birthday parties and hanging out with the neighbours on their porch swing. They loved every minute of it, and it seems impossible we won’t hear their laughter and feel their hugs again.”Yousri says he has been receiving calls for support from around the world.“We appreciate that sympathy and help,” he says. “We’re trying out best to focus on the wife and help her as much as we can.”Michael MacDonald, The Canadian Presslast_img read more

Upcoming Big Ten battles will determine fate of mens soccer team

As the season winds down for the Ohio State men’s soccer team, the remaining stretch of games might be their toughest test yet.Four out of the next five games will be Big Ten showdowns for the Buckeyes. These games will ultimately decide who wins the conference championship and what team could make it to the NCAA tournament. The Buckeyes’ remaining Big Ten opponents are Penn State, Wisconsin, Michigan and Indiana. The lone non-conference game is against West Virginia. Penn State and Indiana are leading the Big Ten, and Wisconsin and Michigan are tied with OSU for fourth place. OSU is within striking distance of claiming that top spot, making the Buckeyes’ next few games very important.OSU plays Penn State on Sunday in a game that could decide who wins the conference. Penn State sits at 2-0-1 in the conference. They have beaten Michigan State on the road, Michigan at home and tied Northwestern. OSU sits at 1-1 in the Big Ten.“If we want a conference championship we have to beat Penn State,” coach John Bluem said. “If we don’t beat Penn State, I would say we’re probably out of the conference championship race already. So for us it becomes a knockout game already.”Kickoff is at 2 p.m. Sunday at Jesse Owens Memorial Stadium. Bluem said that as the season winds down, OSU cannot lose more games. Every game from this point on means a lot in the conference race and the ability to make the NCAA Tournament. read more

Brendan Rodgers slams Celtics League Cup performance

first_imgCeltic advanced to the quarter-finals of the Betfred Scottish League Cup with a 3-1 victory over Patrick Thistle but manager Brendan Rodgers was far from impressed.Celtic manager Brendan Rodgers was unhappy with his side’s performance, saying in the post-match interview that his side was “not very good” and that their “intensity” and “pressure”, were below par, according to Eirsport.Celtic led 1-0 at the break, thanks to a Leigh Griffiths goal, Patrick Thistle equalised on the 73rd minutes.The leveller sparked life into Brendan Rodgers’ side, with two quick-fire goals from Moussa Dembele and Tom Rogic to guarantee Celtic a spot in the last eight of the Scottish League Cup.“We were far too passive in our pressing and [did] not [have] enough intensity. And of course that gave them an opportunity in the game, because of course if you’re slow in that, then normally you’re slow in your attacking play as well.”Leicester City, Manchester UnitedMatch Preview: Manchester United vs Leicester City Boro Tanchev – September 13, 2019 Old Trafford is the venue for the Premier League encounter between Manchester United and Leicester City, which kicks off at 16:00 (CET) on Saturday.“Yeah, okay, we had the ball, and were reasonably comfortable, but a lot of our game wasn’t very good today,” said Rodgers.“When you’re at a club like Celtic you have to win and we didn’t do that [against Athens]. But football, as I say, what you learn is that there are no guarantees, and you always have the opportunity to come back again and we did that today.”“But in terms of performance level, it wasn’t very good,” added Rodgers.“We’ve had a couple of targets we haven’t been able to get in. But I’ll continue to work with the players, and I’ve always had a very good relationship with the board here and that’s the same. We want to improve the team and we’ve got until the end of August to do that.”last_img read more

Thursday Update Hotshot Crews On Standby For Swan Lake Fire

first_imgFire managers with the Division of Forestry are working collaboratively with refuge personnel to manage the fire to reduce future wildland fire hazards and enhance wildlife habitat. The fire is located in an area where no values are threatened or where the likelihood of fire impact to values has been mitigated. Facebook0TwitterEmailPrintFriendly分享As fire managers continue to monitor the Swan Lake Fire, the Pioneer Peak Hotshots and Gannett Glacier Fire Crews are on standby and ready to assist with the 6,951 acre fire north of Sterling when necessary.Aerial photo taken 6/13/19The Fire was estimated at 6,951 acres after a reconnaissance flight Wednesday evening, nearly doubling in size since the previous estimate the night before. Miller: “We did this to minimize the amount of folks that are back there, we had some sightseers going back there to get a closer look. We also want to make sure that any of the firefighters traveling back and forth have a safer route.” Steve Miller with the Kenai National Wildlife Refuge: “We are still just monitoring the fire. What we do now have is a crew that if we do determine that we need to do some suppression activities we can, we have not actively suppressed this fire at all, but we have people setup. Right now it is moving in the best possible direction it can move. The crews are just in case it moves towards one of the existing fire breaks we can either burn off an existing fire break and stop it from heading in a certain direction. We just now have a crew in place to do that.”  Questions or requests for copies of the closure order or maps should be directed to the Refuge at (907) 262-7021. People with  recreational-related questions should contact the Refuge visitor center at (907) 260-2820. The Kenai National Wildlife Refuge has closed the Mystery Creek Road, East Fork Moose River and Enstar Pipeline right-of-way which are north of the Sterling Highway along the eastern edge of the Kenai National Wildlife Refuge. The closure will remain in effect through July 11. Most of the new growth was to the northwest and northeast away from the Sterling highway and 5 ½ miles from the community of Sterling. Sarah Saarloos, with the Division of Forestry: “It continues to burn in that limited protection area of the refuge. The fire burned West into that 2017 East Fork Fire star, so there was movement to the northwest and northeast, similar to the pattern we saw yesterday. We didn’t see any movement South towards the highway so it’s still 2.7 miles North of the Sterling Highway.” The Sterling Highway visibility warning is still in effect around Mile 68 and 75. Motorists are advised to slow down and use caution driving through the fire area due to heavy smoke.last_img read more
