Mosquitos Are Water-Walking Champions


first_imgWe hate ’em, but in one sense we should admire them: mosquitos are the water-walking champions of the animal kingdom.  They even beat out water striders, reported Live Science and EurekAlert based on research from Physical Review E.  Science Daily wrote of “miraculous mosquito legs” and had a picture of the intricate fan-shaped superhydrophobic structures that allow mosquitos to comfortably stand on the surface of water like a cat on a feather pillow.    The legs of water striders can support 15 times their weight on water, but mosquito feet can support 23 times their weight.  “The secret to mosquito water walking appears to be feathery scales a few microns across that in turn are covered with nanoscopic ribbing, forming what the physicists have dubbed (in an apparent fit of excessive prefixing) a micronanostructure.”  That’s something to think about before swatting.    Like geckos, mosquitos take advantage of millions of tiny hairy pads that can adhere to about anything.  Speaking of geckos, PhysOrg reported a new super glue product that was inspired by gecko feet and mussels.  It’s called geckel (gecko + mussel) and has been shown to endure 1,000 repeated applications.  It even works underwater.  National Geographic also reported on the nature-inspired invention.You have to wonder how such intricate micro-machines like mosquitos got to be so nasty.  If they didn’t desire our blood and carry diseases, we would probably not notice them or mind them.  Did they have a beneficial purpose originally, like many other insects still do?  Did they pollinate plants or provide food and games for bats and toads?  Did something go wrong after the original creation?  That’s a question science cannot answer, but theologians can and do try to incorporate the observations of today’s world into the limited record of creation that has been revealed.  It’s clear from the Bible that God has on many occasions used his creatures as agents of judgment – but it is also clear that not every instance of a natural disaster or handicap is related to a specific sin by the victims.  Laymen might retreat to rhymes like: I don’t know why God made the fly, the mosquito, gnat or chigger; I’m just not sad, but indeed glad, he didn’t make them bigger.(Visited 12 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

What is sport climbing


first_img 0 Fitness Sports Tags Post a commentcenter_img Share your voice Getty Images At the 2020 Summer Olympics in Tokyo, we’ll get to watch athletes compete for gold medals in four new sports: karate, surfing, skateboarding and sport climbing (also known as indoor rock climbing).  Rock climbing has been around since — well, since the first time someone tried to climb something rocky. But modern recreational climbing started in the 19th century, with Sport Climbing only emerging in the 1970s and ’80s. In traditional climbing, sport climbing’s outdoor counterpart, the focus is typically on scaling a route or reaching the top of a natural landmark. A lead climber will place bolts on a mountain as they go, typically with hand drills, then remove them once they are complete. The climbers use ropes to protect themselves against falls. gettyimages-1127551032.jpgTraditional climbing takes place outside without a predetermined route. Getty Images In contrast, sport climbing takes place on engineered or indoor routes where climbers are using protection already bolted in place. They practice in pursuit of physical perfection and strategy as opposed to vertical height. Rock climbing has evolved as a catch-all term for many different sports, including everything from free soloing to bouldering. With that in mind, here’s everything you need to know about sport climbing at the 2020 Olympics. Sport climbing events at the 2020 Olympics Sport climbing will be broken up into three separate disciplines: speed climbing, lead climbing and bouldering. Not every country will be represented; only 20 athletes per gender (40 climbers total) will be allowed to compete at the Games, and only 2 athletes per gender per country will compete in any given event. FYI, the International Olympic Committee currently recognizes only two genders — female and male. There are currently stipulations for athletes that identify as transgender, both female and male, to compete. But there aren’t any guidelines or rulings for athletes who don’t identify as female or male — including those who are nonbinary, agender and genderqueer. Speed climbing48197605737-530595438d-oTwo climbers, one wall. IFSC Speed climbing is relatively simple: there are two climbers with safety ropes and one 15-meter wall set at a 95-degree angle. The climbers race against each other to get to the top, with the fastest one winning.  Bouldering48027672136-56260aac2a-oAthletes use physical and mental precision to climb to the top of a bouldering route. IFSC Bouldering takes place on an even shorter wall, where climbers take turns attempting to scale as many routes on a four-meter-tall wall in 4 minutes. Each route (also called a bouldering problem) is laid out with hand and foot holds in a specific color, and they vary in difficulty based on the size of the holds and the way they are spaced out. A climber completes a problem by grabbing the top hold with both hands. Lead climbing48322747156-585511f9a3-oIn Lead Climbing, participants secure themselves with a rope as they climb higher. IFSC Lead climbing is arguably the most recognizable of the three events. The climber has six minutes to climb as high on a wall that is taller than 15 meters. They use safety ropes that attach to quickdraws on their way up, allowing the rope to run freely while they stay anchored to the wall. If two athletes reach the same point on the wall, the person who got there first is the winner.  In both bouldering and lead climbing, climbers are not allowed to practice climbing on the routes before they compete or watch each other scale the wall, and they only have a couple of minutes to study the routes and decide their strategy before the timer begins. How to qualify for Olympic sport climbing The 40 spots total for sport climbing are going to be hard to nab. One male and one female spot will be reserved for athletes from Japan, the host country. Another man and woman will be chosen by the Tripartite Commission, who give Olympic spots out to qualified athletes in special circumstances. If you were counting on your toes and fingers, that leaves 36 total spots left.  The rest of the spots will be determined through a series of qualifying events taking place from August 2019 till spring 2020.  IFSC Combined World Championships The championship event for the International Federation of Sport Climbing will take place on August 20-21, 2019 in Toyko, Japan. The top seven women and top seven men will each receive Olympic invitations. Because each country can only have two male and two female athletes, if one country has many female competitors in the top seven, only the top two will be invited and other women further down the list will get bids (the same goes for the men).  Olympic qualifying event  This will take place on November 28-December 1, 2019, in Toulouse, France. Athletes that have already qualified for the Olympics will not attend. The only invited athletes will be the top 20 climbers on the IFSC’s World Cup circuit, so climbers will be encouraged to participate in the World season. Similar rules as the last event apply, but this time only 6 female and 6 male athletes will get Olympic bids (and again, only 4 total from each country).  If you’re still managing to count along, you’ll notice that there’s only five spots for men and five for women remaining. Instead of any more mega-events, the rest of bids will be determined through a series of continental championships.  Continental championships Athletes that still haven’t qualified can compete in these events, but there’s a twist: climbers can only participate in the event that their climbing federation is a member of. So, a climber from the US can only compete in the Pan-Am event. The male and female winners from each event will be awarded a spot, but if their country has already met its limit of four athletes total, the Olympic bid will go to the next in line.  The first continental championship is the Pan-Am event on Feb. 27 to March 1, 2020 at Sender One in Los Angeles, California. The next four take place in April through May of 2020 in each major continent. Medaling system tokyo-2020-medalsThe Olympic and Paralympic medals are made from recycled electronics. Tokyo 2020 If you thought the qualifying system was a bit complicated, take a deep breath. There’s only one set of medals awarded per gender, so all three events will go into determining which country gets the gold, silver and bronze. The speed climbing discipline will be done in a bracket format, with athletes competing head to head, while bouldering is in a leaderboard format. Lead climbing will have a point system in which each hold on the wall counts as one point and the athlete who climbs the highest will obtain the highest score. Once all the athletes are ordered by placement per event, their placement numbers will be multiplied, and the climbers with the lowest scores will win medals. Because of the scoring format, each climber will compete in each event. For example, if an athlete gets second place in speed climbing, third in bouldering and first in lead climbing their overall score would be six (2 times 3 times 1 equals 6).  Sport climbing schedule The Olympic master schedule has already been released, with sport climbing qualifying events on Aug. 4 and 5, 2020. The finals will be on Aug. 6 and 7. In the US, NBC will broadcast events, with the BBC securing rights in England and Channel Seven, 7Mate and 7Two in Australia. All events will take place at the Aomi Urban Sports Park in Tokyo. last_img read more

JPMorgan Citi shareholders to vote on potential breakup plans


first_imgShareholders of JPMorgan Chase & Co and Citigroup Inc will get to vote on whether their banks should consider breaking into smaller pieces.Citigroup included the question in a proxy statement it filed on Wednesday for its annual meeting next month, and the shareholder sponsoring that proposal said he has a similar one slated for the upcoming ballot for JPMorgan’s annual meeting.The shareholder, Bart Naylor, said he hopes the proposals get more votes than the 4 percent he got for a measure last year that called for Bank of America Corp to break up.The Citigroup and JPMorgan proposals “are more deferential to the boards in asking them to study the vicissitudes of a breakup,” Naylor said in an interview. He hopes proxy advisory firms, which often sway one-third of votes with their recommendations to institutional investors, will back studies by directors even if they won’t tell directors to break up the banks.”These banks are too big to manage,” Naylor said.Citigroup directors opposed Naylor’s resolution in Wednesday’s filing, noting that the company has undertaken a transformation on its own to become smaller and more efficient. Citigroup has shed more than $500 billion of assets since 2008.A JPMorgan spokesman declined to comment on Naylor’s proposal. Chief Executive Officer Jamie Dimon has said that JPMorgan is stronger because of its large and diverse businesses.Naylor said he failed to get a similar measure on the slate for the next Bank of America shareholders meeting because he made a mistake and did not properly certify that he owned shares.The Wall Street Journal reported earlier on Wednesday that Naylor’s proposals would be on the ballots.The breakup of large banks into smaller ones has been an issue on the U.S. campaign trail.U.S. Senator Bernie Sanders of Vermont, who has drawn the support of the Democratic Party’s populist wing in his run for the party’s presidential nomination, has said he would create a “too-big-to-fail list of commercial banks, shadow banks, and insurance companies” and break them up in the first year of his administration.last_img read more
