WainrightRoslyn DakinsciencetongueUniversity of British Columbiawings,Trending Requesting a (Partial) Retraction from Darrel Falk and BioLogos Many people keep hummingbird feeders in their back yards, to enjoy the aerobatics of these colorful, quicker-than-the-eye, miniature marvels. Paul Nelson says, “There’s a kind of jewel-like quality that they have” that makes them so admirable. In Flight: The Genius of Birds, after seeing details about hummingbird science set to dazzling video, it’s no wonder Nelson speaks of the “exquisite workmanship” evident in their construction.The big question facing science should be, “How did such exquisite workmanship come about?” How can a creature weighing only a few ounces perform maneuvers that flight engineers cannot begin to imitate? And yet evolutionists often seem fixated on much smaller questions, such as “How did one hummer evolve to be larger than another hummer?” A good example of this comes from the University of British Columbia, which announces, “Evolution — and skill — help hefty hummingbirds stay spry.” Looking right past the magnificent photo of a hummingbird’s iridescent feathers and beautiful head and eyes, the authors rush to give credit to blind processes of nature, right from the first word.Evolved differences in muscle power and wing size — along with a touch of skill — govern hummingbirds’ inflight agility, according to new research in Science.The findings by University of British Columbia biologists show that larger species of hummingbirds, despite their increased mass, are able to adapt to outmaneuver smaller species.“Studies of bats, birds and other animals show that increases in body mass can have a detrimental effect on many aspects of flight,” says Roslyn Dakin, co-lead author on the study.“But with hummingbirds, the correlated evolution of increased wing size and muscle mass helps larger species compensate for their greater body masses.” [Emphasis added.]You can summarize all the lessons of this study published in Science in just one sentence: “Bigger hummingbirds evolved bigger muscles, and smaller hummingbirds evolved smaller muscles, but all of them can maneuver equally well.” Fascinating. Science marches on.It’s not that the scientists were lazy. Dakin et al. “recorded over 330,000 maneuvers, including many repeated maneuvers for each bird.”How does agility evolve? This question is challenging because natural movement has many degrees of freedom and can be influenced by multiple traits. We used computer vision to record thousands of translations, rotations, and turns from more than 200 hummingbirds from 25 species, revealing that distinct performance metrics are correlated and that species diverge in their maneuvering style. Our analysis demonstrates that the enhanced maneuverability of larger species is explained by their proportionately greater muscle capacity and lower wing loading. Fast acceleration maneuvers evolve by recruiting changes in muscle capacity, whereas fast rotations and sharp turns evolve by recruiting changes in wing morphology. Both species and individuals use turns that play to their strengths. These results demonstrate how both skill and biomechanical traits shape maneuvering behavior.Evolve, evolve, evolve. Everything is explainable by Darwin’s blind process of mistakes that survived the trash heap. That includes “both skill and biomechanical traits” because they are results of evolution, too. Is science advanced by work that ends up saying, “big hummingbirds evolved to be bigger, and small hummingbirds evolved to be smaller”? It wouldn’t matter if they recorded 500,000 maneuvers, or a million maneuvers. The fix was in: evolution would take all the credit.This result explains why hummingbird maneuverability scales positively with species mass, even though mass has the opposite effect on individual performance: Larger species can achieve maneuverability through the evolution of disproportionate increases in muscle capacity and wing size.It’s hard to even call natural selection a “process.” It’s more like a statement after the fact, a filter that allows one conclusion but omits all others. Natural selection is not an active agent; it doesn’t cause anything. The bird doesn’t choose to evolve, and the environment doesn’t make it evolve. The Darwinian just looks at the finished product, and says, “it evolved.” The reader is left looking at this masterpiece of flying jewelry, wondering if anything has been explained at all.Thus, species-level evolutionary changes in muscle capacity and wing morphology affect different, correlated suites of behaviors.No doubt this study took a lot of work, but the evolution statements do not logically emerge from the data. The scientists learned things about feathers, wing shapes, glycolysis in the muscles, and other measurable factors between different hummingbird species. But what’s evolution got to do with it?Given that muscle capacity is the primary species-level trait associated with accelerations this result suggests that evolved changes in muscle capacity can compensate for relatively small wings.The uselessness of evolutionary explanations can be seen by substituting the word “happenstance” for “evolve” in one of their concluding paragraphs:A key result of our comparative analysis is that evolved [happenstance] changes in the wings primarily determine turns and rotations, whereas evolved [happenstance] changes in muscle capacity primarily determine translations. This indicates that different flight maneuvers evolve by [happenstance] recruiting different traits.Lest any evolutionist complain that we’re leaving out the ‘selection’ part of the equation, it must be noted that selection is by happenstance, too. No mind is governing the outcome in the Darwinian view of the world. ‘But if selection didn’t operate, the bird would not survive!’ is the comeback. OK then, how satisfying is it to explain anything with the statement, “If it didn’t evolve, it wouldn’t exist”? It’s like the anthropic principle in cosmology, which (in one version) states, “If the universe were not finely tuned to an astonishingly intricate degree, we wouldn’t be here arguing about it, so it must have just happened to work out that way.” There’s something deeply unsatisfying in that kind of explanation.The paper by Dakin et al., notice, is trying to explain hummingbird differences by evolution. Peter C. Wainright, in a companion piece in Science, points to the paper with the “how” word: “How hummingbirds stay nimble on the wing.” He says the authors “probe the evolution of flight maneuverability in hummingbirds”; he speaks of “the evolution” of hummingbirds; he mentions “the role of flight ability evolution in hummingbird diversification.” Our contention is, what’s the e-word got to do with it? For anything learned about hummingbird maneuverability due to wing shape, tail rotation, or muscle mass, does it help to say that evolution (happenstance) did it? Does this improve scientific understanding of a wonder of nature? Thinking people want to know how this wonder came about. Happenstance is not an answer. It is not an explanation.You’ll learn more about hummingbirds in nine minutes of the Illustra film than in this paper with its 64 references and 18 mentions of evolution. You’ll learn that:Engineers are light-years behind the bird that inspired robotic flyers.Their wings can beat more than 100 times a second.Hummingbirds are built for speed and maneuverability.No other bird can fly backward and hover in mid-air while feeding on flowers.The highly-maneuverable tail is a balancing organ the bird uses to guide direction.The flight muscle represents about 43% of the bird’s mass.Hummingbirds employ 3 specialized types of wing beats for forward, backward, and hovering motion.Hummers have a unique shoulder joint that enables these flight strategies.Unlike on any other bird, hummingbird wings generate lift on the backstroke.The shoulder joint can rotate the wing 140 degrees by twisting the upper arm bone, making the entire wing invert on the backstroke.To supply the muscles with oxygen, the bird’s heart beats as much as 1,250 beats per minute.The nerve synapses fire at an incredible rate to make this muscular contraction possible.The hummingbird consumes twice its body weight in nutrients each day.During waking hours, the bird eats every 10 to 15 minutes.A comparable diet for a human would be 150 pounds of food a day.The hummingbird tongue is about twice as long as its beak.The tongue acts as an automatic nectar trap (see video clip for demonstration).The tongue traps nectar in less than 1/20th of a second, thousands of times a day.Surely these observational facts cry out for an explanation more elegant than, “they evolved.” We respond to these observations, Paul Nelson concludes, like responding to the work of an artist. We doubt that any artist would appreciate having elegant craftsmanship attributed to happenstance.Photo source: Flight: The Genius of Birds, courtesy of Illustra Media.

Housing & Real Estate in Churchill County

first_imgA low cost of living and abundant recreational opportunities in Churchill County contribute to a high quality of life not often found in larger metropolitan areas. In 2017, more than 24,000 people called Churchill County home, according to U.S. Census Bureau estimates. Population density is low — only five people per square mile.Naval Air Station Fallon has approximately 5,000 active-duty personnel, civilian employees, Department of Defense contractors and family members. Many live off base in the surrounding community. Additionally, about 3,100 veterans live in the area, according to the census.Fallon, the county seat, give newcomers plenty of choices when selecting a home. Enlist the help of a reputable real estate agent to help you sort through the area’s home options. The Nevada Association of Realtors is a central source of local real estate information and assistance. Those interested in purchasing a new home can find the expertise and professional services they need at COUNTYChurchill County lies in a broad valley in the high desert of Nevada that was once covered by prehistoric Lake Lahontan. Churchill County was created by the Nevada State Legislature in 1864 after Nevada was admitted as a state. Population was sparse; to many people, the area’s 40-mile desert didn’t feel much like a place they wanted to be, though a mammoth irrigation project in later decades made the wastelands bloom, and many settlers came with the water. Comprising approximately 4,930 square miles, Churchill County lies in central northern Nevada, bounded on the east by Lander County, on the south by Mineral County, on the west by Lyon and Washoe counties and on the north by Pershing County.Fallon is the lone city in Churchill County in close proximity to NAS Fallon, although there are other unincorporated places nearby. For more information on Fallon, check out the Fallon Chamber of Commerce website at is the county seat of Churchill County. Originally a ranch store at a “dusty crossroads,” Fallon is experiencing growth and expanding to the north and west. Fallon’s 3.6 square miles is home to many NAS Fallon personnel.The town lies just 70 miles east of the 24-hour excitement of Reno and less than a two-hour drive to the sportsman’s paradise of the Sierra Nevada.A state-of-the-art county hospital serves the Fallon community, including the naval air station. The Churchill County parks and recreation department offers recreation programs, and numerous clubs and organizations provide opportunities for social, recreational and community service activities. Many youth sports and organizations are also available.Situated in the Lahontan Valley, Fallon’s high desert scenery and rugged mountains draw many people to the area. The Cantaloupe Festival & Country Fair, racing events and rodeos attract thousands of visitors annually.The median gross rent in the city was $832 per month, according to the census, and the median selected monthly owner costs of housing units with a mortgage was $1,115. Mean travel time to work for those living in Fallon is about 17 minutes.last_img read more

561 credit unions filed late call reports: NCUA

first_img ShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr by. Nicholas BallasyDespite the NCUA’s decision to enforce penalties against late call report filers, the agency said on Wednesday hundreds of credit unions have filed late for the fourth quarter of 2013.However, the number of credit unions filing late dropped more than two-thirds from the 1,744 late filers at the end of 2012.“A total of 561 federally insured credit unions filed their fourth-quarter Call Reports late or made corrections after the Jan. 24, 2014, deadline,” said NCUA Board Chairman Debbie Matz in a release. “This number is unnecessarily high and unacceptable.”According to the NCUA, an average of 1,048 credit unions did not file on time for the first three quarters of 2013.Matz sent a letter to credit unions in January announcing that the agency would impose civil money penalties on credit unions that file call reports late, starting with the first quarter of 2014.“Penalties would be assessed per day according to ranges set out in the Federal Credit Union Act, but NCUA would ‘consider mitigating factors,’ such as a credit union’s filing history, the gravity of the violation, and other circumstances, such as a natural disaster that prevented timely filing,” said an agency press release. continue reading »last_img read more

MoJ decides against increase in small claims track limit

first_imgThe Ministry of Justice will today confirm there is to be no increase in the small claims court limit.The department is finally set to publish its response later this morning to a consultation on reducing the number and cost of whiplash claims.It will include plans for an independent medical panel to assess whiplash claims from next year.But the increase in the small claims track threshold from £1,000 to £5,000 – a key element of the original consultation – will not be included in the plans.The news will come as a huge relief for claimant personal injury firms that feared for their future if the limit was raised above the level of most whiplash claims.But insurers will be disappointed that they failed to convince the government that a £5,000 limit would help to tackle fraudulent and exaggerated claims.It is understood the MoJ decided to back away from an increase because of concerns raised during the consultation and following the House of Commons transport select committee report, published in the summer, which opposed it.The response is expected to say that previous reforms need more time to take effect, although the government will not rule out a change to the threshold in the future.Justice secretary Chris Grayling today said insurance premiums have already come down by an average of £80 and appeared to suggest this was reason not to address legal costs at this time.He said: ‘It’s not right that people who cheat the insurance system get away with it while forcing up the price for everyone else – so we are now going after whiplash fraudsters and will keep on driving premiums down.’Law Society chief executive Desmond Hudson hailed the MoJ decision to heed the warnings of the transport select committee and maintain the small claims limit at its current level for personal injuries as ‘good news for accident victims and a victory for common sense’.‘It reduces the risk of people with real injuries being fobbed off with less than they are entitled to,’ he said.‘The government has made the right decision in the face of relentless lobbying by the insurance industry seeking to increase the small claims limit and make it more difficult for genuine claimants to obtain just settlements.‘We will be studying the MoJ’s consultation in detail, because we are clear that weeding out false claims must not be at the expense of genuine claimants or radical meddling with the working of the civil justice system with consequent risks.’The Association of British Insurers said the independent panel for whiplash injuries should not be the end of reforms to the sector.James Dalton, the ABI head of motor and liability, said: ‘Setting up independent panels of accredited experts will help the UK shake off its reputation as the whiplash capital of Europe.‘Additional measures, such as increasing the small track claims threshold from £1,000 to £5,000 as we have argued for is also crucial. It would provide not only a simple, speedy, more cost-effective way of settling genuine whiplash claims, but ensure that lower motor premiums can be sustained.’last_img read more

End of an era, Mount Sentinel does not qualify for provincials

first_imgBy Bruce Fuhr,The Nelson Daily SportsIt’s not like the final result was totally unexpected. The 2010 edition of the Mount Sentinel Wildcats was young and inexperienced.Still, when a school has sent a team to the provincial tournament for more than two decades there is bound to be a few unhappy faces walking the halls of the South Slocan-based facility.Fernie Falcons rained on the Mount Sentinel victory parade by stopping the host Cats 15-11 in the fifth game of the bronze medal contest at the Kootenay High School A Girl’s Volleyball Championships Saturday at Castlegar’s Selkirk College.The loss eliminated the Wildcats from attending a record 22 straight B.C. High School A Girl’s Volleyball Championship early next month in Abbotsford.“Although we will not be at the provincials it was not because a lack of effort and preparation,” said Sentinel coach Joe Moreira. “The group worked as hare as any previous teams. We played well at the zone finals and there were no upsets. We were beat by teams that were stronger than us.”Fernie jumped to a 2-0 lead before the Wildcats rallied to square the match at 2-2. The Falcons then upped their service game to win by four points.“As always is the case in the fifth game, the team that can keep their serves in tend to win,” Moreira confessed. “Fernie served better than we did, and won.”The Wildcats finished second in the preliminary round to Selkirk Storm of Kimberley, losing 25-15, 25-17.“We had no answer for National team youth player, Breanna Rauch,” said Moreira.In the quarterfinal round Mount Sentinel and Fernie each won to advance to the semi finals.A surprisingly strong team from Elkford knocked off the Cats 25-21, 25-13, 29-27.“In the second game their serving beat us up, but we rebounded nicely in the third but (Elkford) got to 29 before we did,” he said.Selkirk earned the first seed from the Kootenays by stopping Elkford in the final 25-20, 25-22, 26-24.“We played this Kootenay Final the way we had played during the season,” Moreira explained. “No surprises . . . we are a fairly young team with four Grade 10 players that carry a fairly big load and the load was pretty heavy this weekend.”The last time a team from Mount Sentinel did not qualify for the provincial tournament came in 1987 when Salmo ousted the Cats.During a stretch from 1991 to 2009 Mount Sentinel teams won four provincial titles — 1997, 2002, 2004, 2007 — and finished second or third eight times.“Although we will not be in attendance this year, we will return,” Moreira [email protected]last_img read more

Saints dip into Grizzlies den and add Lucas Hildebrand to roster for next season

first_imgAnother week, another signing by the braintrust of the Selkirk College Saints Men’s Hockey program.Staff is pleased to announce a commitment from defenceman Lucas Hildebrand of Vancouver, B.C. to attend the Castlegar-based school for the upcoming 2012/13 B.C. Intercollegiate Hockey League season.Hildebrand joins the Saints following three seasons in the Kootenay International Junior Hockey League, which he split between the Grand Forks Border Bruins and the Revelstoke Grizzlies.He was Revelstoke’s highest scoring defenceman during the 2011/12 season with seven goals and 30 assists in 49 games, helping the Grizzlies to a 37-11-0-4 record and a first place finish in the Okanagan/Shuswap Conference.  He was honoured with the Grizzlies’ Best Defenceman award at the conclusion of the season. “Lucas is a player we’ve been focused on for a while now and I’m very excited that he’s made the decision to pursue his education at Selkirk College,” says Saints head coach Jeff Dubois.”He comes to us on a very good recommendation from his coach in Revelstoke and with Vernon of the BCHL, where he played some games as a 20-year old last season.” At 6-foot-4 and 200-pounds, Hildebrand brings size and a big shot to the Saints’ blueline. “I’m excited to come to Selkirk for the opportunity to meet new people, play a high level of hockey and start a new chapter in my life,” says Hildebrand, who describes himself as a stay-at-home defenceman with a whatever-it-takes attitude.”I’m looking forward to continuing my hockey career at a great school and starting my schooling with the goal of becoming a firefighter.” Hildebrand is the fourth defenceman to commit to the Saints for the 2012/13 season, joining Brett Kipling (Melville, SJHL), Dylan Smith (Richmond, PIJHL) and Mark Strachan (Kimberley, KIJHL). Also committed to the Saints for the 2012/13 season are forwards Logan Proulx (Cowichan Valley, BCHL), Thomas Hardy (Aldergrove, PIJHL), Jackson Garrett (Comox Valley, VIJHL), Stephen Saretsky (Wellington, OJHL), Cole Thomson (Kerry Park, VIJHL), Scott Swiston (Creston, KIJHL), Connor McLaughlin (Fernie, KIJHL), Kyle Golz (Grandview, PIJHL), Cody Fidgett (Delta, PIJHL), John Proctor (Delta, PIJHL), Matthew Luongo (Aldergrove, PIJHL), Jared Seutter (Chase, KIJHL) and Brodie Gibbon (Oceanside, VIJHL) as well as goaltender Stephen Wolff (Oceanside, VIJHL).last_img read more
