first_imgDonegal County Council has been urged to monitor a deluge of ‘agricultural litter’ that is blighting the coastline near Lough Foyle. A local councillor for Inishowen raised concerns over the pollution to the Environmental Department of the authority last week.Cllr Terry Crossan, who highlighted the build-up of plastic bags and rubber bands on the coastline between Muff and Greencastle, said a number of residents had expressed their concerns over the ongoing issue. The Sinn Fein councillor said: “As a result, there has been a lot of pollution in the area including plastic bags, which are no-way biodegradable, and rubber bands.“There is also an encroachment on wildlife habitats and I have a lot of my constituents, who are very environmentally minded, making representation to me over the increasing amount of waste and pollution along the coastline.“And I would like to ask the council to oversee an environmental impact towards this pollution on our coastline along the Lough Foyle.”Mathew Byrne, Waste Protection Officer for Donegal County Council, said: “It is a problem and I will talk to relevant parties and see if we can engage with these fish farms. “There is a difficulty linking the litter back to the fish farms, so it isn’t as straight forward as people may think.” Council to engage with fish farmers over Lough Foyle pollution was last modified: October 29th, 2019 by Shaun KeenanShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window)last_img read more

first_imgWhat Good Is Natural Selection without Progress?Everything You Know About Natural Selection Is WrongMisuse of Term ‘Natural Selection’ Continues Can anyone name any real, true thing that Darwin’s phrase “natural selection” has done to further understanding of nature?Credit: J.B. GreeneBrace yourself. We’re going to say that natural selection is useless for science. Secular scientists will scream. Even some creationists will harrumph. But you need look no further than scientific journals and science news sites to see that it is true. Natural selection is a storytelling plot that contributes nothing to real, useful knowledge about nature. It’s like colorful frosting, but not the cake.  It’s like graffiti on a wall that does nothing to hold the building up. It’s like a gaudy pattern on a hot-air balloon, but not the heat engine that lifts it.If scientists ditched the phrase natural selection entirely, science would go on just fine. In fact, it would go on better without all the distractions offered by this empty, useless phrase that Darwin invented. Here’s our challenge: can you name any one, true, real thing that “natural selection” has added to our understanding of the world? While we wait for a response, it’s time to back up our audacious claim with specific examples from the science news.Articles Employing “Natural Selection” with No Added ValueSpotting evolution among us (Science Magazine). We’ll start right at the top with the premiere science journal in America, Science, the voice of the American Association for the Advancement of Science (AAAS), in a paper published just this week. Writer Ann Gibbons uses the phrase natural selection (hence NS) a whopping 13 times, determined to show that it helps scientists make sense of the world. Does NS advance science, a goal for which the AAAS is named? Remember now, we are looking for understanding, not storytelling. We must overlook the fluff of a high perhapsimaybecouldness index (PMCI) We want some meat in the science. Where’s the beef?“In addition to unearthing archaic DNA, the studies are pinpointing genes that natural selection may now be winnowing out of the gene pool and other genes—for example those linked to fertility—that it may be favoring.”  The phrase “may not” is just as suitable as “may” here. Come back when you have the beef.“The pair wondered whether other gene variants affect survival so dramatically—and whether natural selection is weeding them out.” Come back when you stop wondering and have evidence.“When it comes to natural selection in humans, most studies have only been able to detect dramatic cases thousands or millions of years ago in genes of known function.” Circular reasoning. Those studies assume natural selection did the work. None of the researchers witnessed millions of years, let alone thousands.“Now, Pickrell and Przeworski wondered whether they could detect genetic variants that affect survival today—and whether natural selection in recent generations has been weeding out harmful ones or favoring beneficial ones.” Come back when you stop wondering and have proof. Is NS doing this by intelligent design? What is it, a god?“Nearly all the variants they examined persisted at the same frequency even into old age, suggesting they had no large effect on survival. That implies natural selection has efficiently weeded out harmful variants, even if they act only in old age—perhaps, Przeworski speculates, because the variants curb older men’s fecundity. Or perhaps the hypothesized benefit that healthy grandmothers confer on grandchildren was at work.” High PMCI. Well, which is it? Too vague to be scientific. And since everything dies, there’s no way to blame it on NS. This is not NS; it is differential death. No new information. No innovation. No progress from molecules to man.“The researchers concluded that natural selection has not yet had time to eliminate these two alleles, perhaps because changes in the environment and human behavior only recently made them deadly….” More perhapses. Darwin was not trying to eliminate things. He was trying to say NS causes bacteria to evolve into man. Cliffs in the environment are deadly, too. Is that an example of NS?“Natural selection may have preserved those variants even though they shorten life span because they also boosted fertility.” More storytelling and speculation.“But researchers have been unable to tie those trends to underlying genes to get direct evidence of natural selection.” NS theory is doing a great job helping our understanding, isn’t it?“The UK Biobank allows us to show that natural selection not only took place in the past, but it’s still ongoing,” Visscher says. More circular reasoning. Visscher is studying genes “thought to increase fertility.” But fertility is no guarantee of progress in fitness. The offspring could all be afflicted by worse traits, and some mammals with low fertility survive just fine. Now read the very next sentence:“Teasing out natural selection from other factors shaping genes can be tricky, however, especially when multiple genes work together to influence complex traits, such as height. About 5000 gene variants simultaneously influence a person’s height, some boosting it, some reducing it….” This undermines Visscher’s assertion. He has no way to establish NS as the cause of increased fertility. It’s just his preferred explanation – a story – out of thousands of potential alternative explanations.“Berg and others suggested natural selection had favored tallness in the Yamnaya or their ancestors, and ancient DNA reveals that the Yamnaya were tall.” Wait for it:“It’s true people in northern Europe are taller on average, but there is no evidence this has anything to do with natural selection,” Berg says.” Gotta love this natural selection. It’s as substantive and nutritious as cotton candy.“Although UKB data cast doubt on natural selection’s role in that case, they do suggest that evolution has favored genes for shortness in pygmy populations on the island of Flores in Indonesia.” What? Evolutionists imbibe NS smoke and become racists again? For shame!There you have it. Ann Gibbons had a PERFECT opportunity to show that NS adds value to our understanding. Between the admissions of ignorance you saw only speculative assertions. BAD bluffing assertion were offered in one sentence only to be taken away in the next. Everything is vague, imprecise speculation heavily seasoned with may, perhaps, and could. Such words are unworthy of scientific understanding. If you buy these evolutionists’ stories, we have a resort vacation to offer you on the Isle of DeBris.We have more examples to share to prove our contention that NS is useless, but we wanted to start big. More will be forthcoming, followed by examples of good biological science that completely ignores NS. Meanwhile, offer your best example of NS adding some value to science. Go ahead; give it your best shot. But you had better read up on some of our earlier articles about NS first, so that you don’t fall into the pitfalls of shallow thinking.Op-Ed: Time to Ditch Natural Selection?Darwinians Cannot Agree on What Natural Selection Is (Visited 496 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Marlize Lombard, a researcher andlecturer in Anthropology at the Universityof Johannesburg, at the Sibundu Cave sitein the north of KwaZulu-Natal province.(Images: University of Johannesburg)MEDIA CONTACTS• Lyn WadleyHonorary Professor, School of Geography,Archaeology and Environmental StudiesUniversity of the Witwatersrand+27 11 717 [email protected] African archaeologists have found what is believed to be the earliest evidence of human-made stone-tipped arrows, 64 000-year-old stone tools – still with traces of blood and bone – that push the development of bow-and-arrow technology back 20 000 years and throw light on humanity’s cognitive development.The finds, unearthed from layers of very old sediment in Sibundu Cave in the north of KwaZulu-Natal province, were made by Marlize Lombard of the University of Johannesburg and a team of researchers and scientists under the leadership of Lyn Wadley of the University of the Witwatersrand (Wits), also in Johannesburg.A bone point that could have been an arrow tip was also excavated from the site in 2008 by Lucinda Backwell and colleagues from Wits.The shape of the geometric stone pieces indicated where they had been impacted and damaged, and how they were hafted, Lombard said. “This showed that the pieces were very likely to have been the tips of projectiles – rather than sharp points on the end of hand-held spears.”In addition to the blood and bone, the arrow heads also held traces of glue in the form of a plant-based resin that the scientists think was used to fasten them onto wooden or reed shafts.“The presence of glue implies that people were able to produce composite tools – tools where different elements produced from different materials are glued together to make a single artefact,” said Lombard.The sophistication of the arrows sheds light on the development of human intelligence, scientists believe. According to Larry Barham from the University of Liverpool, “This is an indicator of a cognitively demanding behaviour.”The discovery, together with other evidence, pushes back the development of bow-and-arrow technology by at least 20 000 years. The team’s findings were published in the latest issue journal Antiquity.Ancient engineering Scientists’ interest in early bows and arrows stems from the light the weapons shine on the technological and cognitive abilities of early Homo sapiens.“Hunting with a bow and arrow requires intricate multi-staged planning, material collection and tool preparation and implies a range of innovative social and communication skills,” the researchers wrote in their article.Lombard said that her ultimate aim was to explore the big question: “When did we start to think in the same way that we do now?”“Together with additional evidence from Sibudu produced by Prof Wadley and her team, and other South African sites such as Blombos, under the direction of Prof Chris Henshilwood, we are becoming more and more confident that 60 000 to 70 000 years ago, in Southern Africa, people were behaving, on a cognitive level, very similarly to us.”Chris Stringer from the Natural History Museum in London said the work added to the view that modern humans in Africa 60 000 years ago had begun to hunt in a “new way”.Neanderthals and early humans, he explained, were likely to have been “ambush predators”, who needed to get close to their prey in order to dispatch them.“This work further extends the advanced behaviours inferred for early modern people in Africa,” Stringer said. “But the long gaps in the subsequent record of bows and arrows may mean that regular use of these weapons did not come until much later.“Indeed, the concept of bows and arrows may even have had to be reinvented many millennia later.”last_img read more

first_img14 November 2011Nineteen-year-old swimming sensation Chad le Clos secured the overall Fina/Arena World Cup title in Japan on the weekend, joining Ryk Neethling and Cameron van der Burgh as South Africans who have captured the prestigious title.After claiming the $100 000 (approximately R788 000) first prize, Le Clos, in an interview with Fina, revealed that he had enjoyed a fair share of good luck on his way to the title because he had begun the season as a late replacement.“I was lucky to be in the series and the great start in Dubai (where he won six gold medals) gave me the possibility of making the top three and possibly winning.”Le Clos twice delivered six gold medal performances; apart from Dubai, he also achieved the feat in Beijing.Tough scheduleSwimming in his seventh and final meet in Tokyo, Le Clos admitted that it was tough to maintain his form through so much time and travel, with events taking place in Dubai, Stockholm, Moscow, Berlin, Singapore, Beijing, and Tokyo, between 7 October and 13 November.In Tokyo, he won the 200 metres freestyle, which was his 22nd win during the World Cup Series. He also picked up silver medals in the 200m butterfly, 200m individual medley, and 100m individual medley, and added a bronze in the 100m freestyle in which Olympic champion Alain Bernard finished fourth.His final margin of victory in the overall World Cup standings was substantial. Le Clos claimed first place with 176 points. Second went to Japan’s Hidemasa Sano on 90 points, with Germany’s Marco Koch in third with 65 points.‘They were gunning for me’Looking back on his performances in Japan, Le Clos said: “I knew it was going to be hard and that there were some wonderful Japanese and Chinese swimmers, who are good at medleys, breaststroke and butterfly. They were gunning for me, as you could see.”Questioned about what he enjoyed most about the World Cup, Le Clos said: “Swimming against the best in the world and getting to swim against Michael Phelps and Ryan Lochte. If you want to win Olympic gold, you have to beat those swimmers.”He summed up his World Cup season by saying: “It’s been a tough World Cup and I learned so much. I made a few mistakes but enjoyed the experience and the support has been amazing.“Thank you to my sponsors and Olympic Federation for the support for my success at the World Cup. A special thanks to my coach Graham Hill for a solid preparation.”Cherry on the topBack home, there was a cherry on the top for Le Clos; he won the Most Promising Athlete award at the Telkom Swimming South Africa Aquatic Awards in Kempton Park on Saturday.The Swimmer of the Year award went the way of two-time World Series winner Cameron van der Burgh.Would you like to use this article in your publication or on your website?

first_imgNormal anatomyThe anterior cruciate ligament (ACL) is a ligament in the center of the knee that prevents the shin bone (tibia) from moving forward on the thigh bone (femur).IndicationsIf the ACL is torn, the knee joint may become unstable and affect the ability to perform work or athletic activities.Procedure, part 1ACL reconstruction is surgery to replace the torn ACL ligament. There are several choices of tissue to use for the new ligament, including an autograft (tissue from the patient?s own body) or an allograft (tissue from a cadaver). One of the most common autografts use part of the patellar tendon (the tendon in the front of the knee).Procedure, part 2The old ligament is removed using a shaver or other instruments. Bone tunnels are made to place the new ligament (patellar graft) in the knee at the site of the old ACL. Screws are commonly used to secure the graft in the bone tunnels, although other methods of fixation are used depending on the type of graft used.AftercareAt the end of the surgery, the incisions are closed, and a dressing is applied. ACL reconstruction is usually a very successful surgery. The majority of patients will have a stable knee that does not give way after ACL reconstruction.Review Date:8/14/2011Reviewed By:Linda J.
