Scientists at University of Illinois studied dynein and kinesin – the tiny molecular trucks that ferry cargo inside the living cell – and found that they are not just individualists: they cooperate in a delicate yet effective performance. Some scientists had thought that the two machine types, which travel in opposite directions, were involved in a constant tug-o’war with each other. Instead, reports the university’s news bureau, “The motors cooperate in a delicate choreography of steps.” Using high-speed imaging techniques, they determined that “multiple motors can work in concert, producing more than 10 times the speed of individual motors measured outside the cell.” The machines move by “walking” on rails called microtubules in steps 8 billionths of a meter at a time. The team is measuring the force produced by the motion to “further understand these marvelous little machines.” There was no mention of evolution in the report.Someone should put an animation of these machines to the Blue Danube Waltz. It would be quite a show. Darwinists could be allowed to buy tickets as long as they do their smoking outside.(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0
Imprecise language confuses the evolution issue, making it seem like goal-directed activity of intelligent minds mimics Darwinism.Cultural EvolutionThe authors of a paper in PNAS might be forgiven for speaking of ‘cultural evolution’ in their paper on classical literature, because they don’t really mention mutations or natural selection. However, the word evolution is so tainted by Darwinism these days, is their meaning clear?We trace the evolution of features not tied to individual words across diverse corpora and provide statistical evidence to support interpretive hypotheses of literary critical interest. The significance of this approach is the integration of quantitative and humanistic methods to address aspects of cultural evolution.The summary on Phys.org, however, adds to the confusion with its imprecise meanings:“There is a growing appreciation that culture evolves and that language can be studied as a cultural artifact, but there has been less research focused specifically on the cultural evolution of literature,” said the study’s lead author Joseph Dexter, a Ph.D. candidate in systems biology at Harvard University.The link in that quote produces a page mixed with goal-directed or mindful change and biological change due to neo-Darwinism. So is cultural evolution something that just happens randomly like biological change, or not? Readers are left thinking the two concepts can be intermixed.Meteorological EvolutionA worse case of equivocation has emerged from the University of Wisconsin-Milwaukee. Science Daily‘s headline says, “Meteorologist applies biological evolution to forecasting,” tying in the science of weather forecasting directly to Darwin:What if a computer model could improve itself over time without requiring additional data? One researcher has made weather forecasting more accurate by repurposing an idea from Charles Darwin.It might seem to some commuters without umbrellas that forecasters roll dice, but the story is about Paul Roebber, “an innovator in weather prediction.” Presumably he is trying by intelligent design to improve the art and science of a fiendishly difficult field with many variables. While he may vary his inputs, he very sincerely chooses the outputs, having a goal to increase the reliability of his craft.To boost the accuracy, forecasters don’t rely on just one model. They use “ensemble” modeling — which takes an average of many different weather models. But ensemble modeling isn’t as accurate as it could be unless new data are collected and added. That can be expensive.So Roebber applied a mathematical equivalent of Charles Darwin’s theory of evolution to the problem. He devised a method in which one computer program sorts 10,000 other ones, improving itself over time using strategies, such as heredity, mutation and natural selection.The wording is entirely misleading. Heredity is not a strategy if Darwin’s theory is true; it’s an outcome of a long series of mistakes. Mutation is clearly not a strategy, any more than a random meteor strike. Least of all is natural selection a ‘strategy.’ If Roebber were really using natural selection, he would walk away from the computer and let stuff happen on its own. Clearly he watches the outcome and guides it toward his goal ‘to boost the accuracy’ of forecasting.In other words, Roebber is doing artificial selection, a form of intelligent design. The only thing his work has in common with Darwin is this: they both used the same fallacy of equivocation, confusing artificial selection with natural selection.Nature favors diversity because it foils the possibility of one threat destroying an entire population at once. Darwin observed this in a population of Galapagos Islands finches in 1835. The birds divided into smaller groups, each residing in different locations around the islands. Over time, they adapted to their specific habitat, making each group distinct from the others.Applying this to weather prediction models, Roebber began by subdividing the existing variables into conditional scenarios: The value of a variable would be set one way under one condition, but be set differently under another condition.The computer program he created picks out the variables that best accomplishes the goal and then recombines them. In terms of weather prediction, that means, the “offspring” models improve in accuracy because they block more of the unhelpful attributes.So did the finches create computer programs, too? Did they hold a committee and say, ‘We need to subdivide into smaller groups to avoid threats’? Obviously not. Darwin could not have cared less if they all died in one threat, or died separately in separate threats. The birds did not choose to adapt. If they had all perished, Darwin would have explained that, too.Roebber looks at the outcome of the Galapagos finch population distribution, and presupposes that it occurred by a Darwinian mechanism, ignoring the possibility that organisms are designed to adapt. To the extent he thinks the finches divided on purpose, he also commits the fallacy of personification. By contrast, Roebber himself had a goal in his research. Purposely working toward a goal by applying an intelligent strategy is not Darwinian.As a reward for his equivocation, the government gave Roebber $500,000 in funding. If his work helps commuters know when to bring an umbrella, they will be happy and not care about the Darwinese. They don’t need the narrative gloss that Darwin helped him with his intelligent design.Evolution is a god to the science research and media culture, capable of innovation, progress, and adaptation. Evolutionists think they are pleasing Darwin by being Darwin-like the way Christians try to please God by being Christ-like. The Darwinians imbue all the attributes of God onto natural selection. They fall down and worship its omniscience and omnipotence. They might as well be singing Darwin’s praises in hymns. (Visited 135 times, 1 visits today)FacebookTwitterPinterestSave分享0
Share Facebook Twitter Google + LinkedIn Pinterest By Russ QuinnDTN Staff ReporterOMAHA (DTN) — With much of the Corn Belt facing a late-maturing, high-moisture crop, some farmers are already making plans to dry their grain this fall. That means they’ll likely need to purchase propane — if they haven’t already — to fuel their grain dryers.Late summer and early fall is the time many farmers lock in propane prices for the grain-drying season. With a wet spring delaying planting this year, especially in the Eastern Corn Belt, there could be a lot of wet grain to dry this fall.Right now, propane prices are low thanks to high production of the fuel, according to propane analysts. But high demand for propane during harvest followed by a cold winter could push prices higher.PROPANE PRICE AT MULTI-YEAR LOWThere is a good supply of propane in the country as fall harvest begins, said DTN Refined Fuels Reporter Alton Wallace. That has been the case in the U.S. since the beginning of the “Shale Revolution” in 2012, which has allowed the country to dramatically increase crude oil and natural gas production, he said.According to U.S. Energy Information Administration (EIA) statistics, propane production in the U.S. is now roughly about 1.8 million barrels per day (bpd). And production is continuing to increase, Wallace said, growing by 8.3% from 2017 to 2019.“We have a lot of propane right now,” Wallace said.One doesn’t have to be an economist to figure out that if supply outpaces demand, prices will decline, Wallace said. In mid-August, for example, the price of propane at the Conway, Kansas, hub fell to 37 cents per gallon, a three-and-a-half-year low, he said. In mid-September 2018, the price at Conway was near 78 cents a gallon.With propane production at record levels, the market is in an oversupply situation, and prices have been less volatile than in the past, Wallace said.“The U.S. has become an energy superpower because of the Shale Revolution,” he said.While it appears likely that propane prices will be fairly low this fall, there are some factors that could drastically alter that outlook, Wallace said.The propane market can see increased volatility due to the weather, Wallace said. As history has shown, extremely cold winter weather can cause an increase in propane demand and prices can skyrocket quickly. A harvest season in which farmers need more propane to dry down wet crops followed by a cold winter could create a situation where propane prices move considerably higher, he said.Another factor that could affect propane prices is the burgeoning export market.Because of its increased propane production, the U.S. has become a major exporter on the global market, Wallace said. EIA data for the week ended Sept. 13 showed U.S. propane exports at 1.162 million barrels per day.Wallace said companies are building export facilities as this is becoming an important component of the market. The downside to increased propane exports is if export demand for propane rises, those buying propane in the U.S. — such as farmers — are forced to compete for availability with the export market, he said.SOME BOOK PROPANE, SOME DON’TIn August, DTN asked readers about their propane-buying habits. This question was posed in the DTN 360 Poll: “As propane production has increased and domestic demand has been flat, the price of propane has dropped to half its value during the past 12 months. Some farmers may be thinking about their propane needs for the upcoming crop drying and heating. What is your plan for propane this late-summer/fall?”The poll received a total of 171 responses. Of those, 46% said they “Will book propane in August.” Thirty-nine percent said they were “Not going to book propane at all,” while 12% said they “Will book propane in September.” The remaining 3% said they “Will book propane in October.This week, Mark Nowak, a farmer and ag consultant from Wells, Minnesota, told DTN his propane dealer was set to visit him the same day to preorder some of his propane needs. He was set to lock his propane price at $1.08 per gallon, which he said was down from last year ($1.19 per gallon) and 2017 ($1.13 per gallon).There could be a lot of crop drying needed this fall across the Corn Belt, Nowak said. He estimated that most of the corn will black layer by Oct. 1, and thus, the moisture at that time would likely be around 32%.Most farmers harvest corn around 22%-24%, so the crop will need to dry 8% to 10% in October, he said.“I think the month of October is going to be the wildcard here,” Nowak said. “If we continue to see this warm and dry weather, I think the crop can dry down pretty good. But if we see cool and cloudy weather, maybe we will be doing a lot of drying.”CROP MOST BEHIND IN EASTERN CORN BELTCorn and soybean planting was delayed across much of the Corn Belt this spring by wet field conditions, but one region where this was especially true was the Eastern Corn Belt. Areas in Illinois, Indiana and Ohio saw much rain, which pushed planting to as late as the summer in some cases.Brian Scott, who farms near Monticello, Indiana, said his region will see a late harvest this fall. He estimated harvest could be around a month later than normal.“We have a lot of corn that probably won’t black layer until mid-October,” Scott told DTN.Scott said the grain dryers in his region are going to be used this fall. It has been a couple of years since they last used their grain-drying equipment, he said.Scott booked propane earlier this summer — not necessarily because of the amount of drying that could take place this fall, but to take advantage of a summer-fill discounted price. He topped off his 4,000-gallon storage tank like he normally does, he said.There are other farmers who are planning for the increased demand for propane this fall, Scott said. He said he knows of one farmer who built a new propane storage facility so he could get a good price on propane this year. The new facility will allow him to take a full semi-truckload of propane, Scott said.Another farmer who already booked some propane was Mike Cooprider of Howesville, Indiana. He planted his corn from May 18 through June 5. However, he wasn’t able to plant his soybeans until July 15.“Like most farmers, we are praying for a long fall,” Cooprider said.Cooprider said he dries “a lot of corn” every fall, but this year, he could be drying all of his corn crop. For that reason, he has already filled the propane tanks at his bin sites, he said.Russ Quinn can be reached at email@example.comFollow him on Twitter @RussQuinnDTN(AG/CZ)© Copyright 2019 DTN/The Progressive Farmer.

People protested here on Thursday on the busy Mehrauli-Gurgaon road, demanding justice for a five-year-old girl, who was raped after being lured with the promise of a plate of chowmein.The girl, who is under treatment at Delhi’s Safdarjung hospital, was kidnapped from a function in Chakarpur and raped on March 29.People also blocked traffic near Bristol Chowk, and said the girl’s condition deteriorated as proper care was not being given at the hospital. Gurgaon Deputy Commissioner TL Satyaprakash, who visited the spot, assured the angry people that the girl would be shifted to Medanta the Medicity hospital in the city. The protesters demanded the suspension of Gurgaon’s chief medical officer, who referred the girl to Delhi. They also demanded the removal of inquiry officer Assistant Commissioner of Police Dharna Yadav, who allegedly misled the girl’s family saying that the arrested accused was a mentally disturbed person.
