OAKLAND, California (AP):Golden State rolled into the second round of the NBA playoffs without injured superstar Stephen Curry, thoroughly embarrassing the Houston Rockets 114-81 on Wednesday to clinch the series 4-1.Klay Thompson scored 27 points with seven 3-pointers and Draymond Green added 15 points, nine rebounds and eight assists for the Warriors, who will face the winners of the Los Angeles Clippers-Portland Trail Blazers series.Portland lead that series 3-2 after winning at Los Angeles, while Charlotte won narrowly at Miami to also take a 3-2 series lead.Golden State, without their MVP Curry, relied on his fellow ‘Splash Brother’ in Thompson to set the tone from the opening tip. Thompson became the first player in NBA history to make at least seven threes in consecutive playoff games, while Shaun Livingston scored 16 points for his third double-digit performance in three games.deep defendingJames Harden scored 25 of Houston’s 37 first-half points on the way to 35 points, but the Rockets had no chance with a one-man show against the deep defending champions.Portland’s C.J. McCollum scored 27 points to lead the Trail Blazers to a 108-98 win at the Clippers.Damian Lillard added 16 of his 22 in the fourth quarter when Portland pulled away, and the Trail Blazers capitalised on the absence of injured Chris Paul and Blake Griffin to beat Los Angeles.The Blazers are up 3-2 and could close it out tonight in Portland. If Game 7 is needed, it would be tomorrow at Staples Center.Maurice Harkless added 19 points and 10 rebounds, and Mason Plumlee had 10 points and 15 boards for Portland.J.J. Redick led the Clippers with 19 points.Charlotte’s Courtney Lee sank a 3-pointer with 25.2 seconds left to put the visitors ahead to stay, and the Hornets beat Miami 90-88 in Game 5.The Hornets have won three straight games in the series, and will take a 3-2 lead into a potential Game 6 clincher tonight.Marvin Williams led the Hornets with 17 points, while Al Jefferson and Kemba Walker each had 14 for Charlotte.Dwyane Wade scored 25 for Miami, while Luol Deng scored 15, Joe Johnson added 13 and Hassan Whiteside finished with 11 points and 12 rebounds.
Biosonar is a complex ability possessed by toothed whales and dolphins, bats and some birds. It includes both the ability to produce signals and to process the echoes to locate prey. How could such a system evolve? Scientists at UC Berkeley proposed an answer. The press release promised a developing story:Behind the sailor’s lore of fearsome battles between sperm whale and giant squid lies a deep question of evolution: How did these leviathans develop the underwater sonar needed to chase and catch squid in the inky depths?Yet the answer was perplexing: bats and whales developed it by developing it —Now, two evolutionary biologists at the University of California, Berkeley, claim that, just as bats developed sonar to chase flying insects through the darkness, dolphins and other toothed whales also developed sonar to chase schools of squid swimming at night at the surface.Their answer, in other words, provided no information on the sequence of mutations that could have been acted on by natural selection to create a complex, interacting system. It only asserted that the need to dive deep after squid somehow caused the system to be developed – by evolution. From that premise, they wove an evolutionary story of millions of years, based on the assumption that necessity is the mother of invention. ….the first whales entered the ocean from land about 45 million years ago, and apparently did not echolocate…. At the time whales developed biosonar, nautiloids dominated the oceans. Lindberg and Pyenson propose that whales first found it possible to track these hard-shelled creatures in surface waters at night by bouncing sounds off of them, an advantage over whales that relied only on moonlight or starlight. This would have enabled whales to follow the cephalopods as they migrated downwards into the darkness during the day…. Over the millennia, cephalopod species in general – and especially shelled cephalopod species – fell as the number of whale species boomed, possibly because of predation by whales. Then, about 10 million years ago, the whales seem to have driven the nautiloids out of the open ocean into protected reefs. Lindberg said that the decline in nautiloid diversity would have forced whales to perfect their sonar to hunt soft-bodied, migrating squid….The scientists recognized the need for better explanations:The most convincing explanation, that echolocation allowed whales to more efficiently find food in the darkness of the deep ocean, ignores the question of evolution. “How did the whales know there was a large supply of food down in the dark?” asked Lindberg, noting that cephalopods are the most abundant and high-energy resource in the ocean, eaten by 90 percent of all toothed whales. “What were the intermediate evolutionary steps that got whales down there?”Yet the press release never did explain how the system developed – only that evolution saw a need, and by some unspecified process, developed the “sophisticated biosonar system” used by whales today:“Whales didn’t need to have a very sophisticated sonar system to follow the nautiloids, they could just home in on the hard part,” Lindberg said. Only later, he added, did they “develop a complex system with finer resolution to detect and capture soft-bodied squid.”The article pointed to biosonar in bats and whales as “strong examples of convergent evolution” – a term that also hides the “how” of engineering design. They reinforced their claim by pointing to filter-feeding baleen whales and fruit-eating bats that lack sonar because those don’t need the technology to locate their food in the dark. Since both the sonar-equipped bats and whales are nocturnal, the authors presumed evolution provided the equipment needed to hunt at night. They did not speculate why the nocturnal bats and whales didn’t simply switch to daytime food with their diurnal colleagues, nor why the squid didn’t just develop stealth technology to evade the sonar. Apparently, this is an acceptable way to explain things in biology these days. David Lindberg, UC Berkeley professor of integrative biology, said, “thinking from an evolutionary perspective about existing data from biology, paleontology and ecology could answer questions about the origin of echolocation in bats, shrews and other animals.” Presumably, it is now permissible to explain how something developed by saying it just developed – an odd development in scientific explanation.OK, folks, we all just saw their shenanigans right there, which means we have developed a keen sense for seeing things in the dark – a case of convergent perspicacity. Don’t let the ev-illusion squids get away with it.(Visited 20 times, 1 visits today)FacebookTwitterPinterestSave分享0
A 21-year-old law student from Chhattisgarh’s Bilaspur district was raped allegedly y a ‘godman’ based in Rajasthan, police said on Thursday.Based on the woman’s complaint, a case was lodged against 70-year-old Swami Kaushlendra Prapannachari Falahari Maharaj with the women police station here on September 11, said Bilaspur Additional Superintendent of Police Archana Jha.The incident had allegedly taken place at Madhusudan ashram of the godman in Alwar, Rajasthan, on August 7, 2017, she said.As per the complaint, the parents of the woman, who is studying law in Jaipur, are followers of Falahari Maharaj for the past several years, the police officer said.On the baba’s recommendation, she did an internship under a senior lawyer in New Delhi for which she received a stipend of ₹3,000. Her parents asked her to donate the stipend amount to the baba’s ashram in Alwar, the ASP said.Following her parents’ advice, she went to the ashram on Raksha Bandhan in August. Citing occurrence of ‘grahan’ (eclipse) that day, the self-proclaimed religious guru advised her to stay in the ashram which she agreed to, Ms. Jha said.During the night, the baba called the woman in his room and allegedly sexually assaulted her, the ASP said, quoting from the complaint.The baba asked her not to tell anyone about the incident and threatened to harm her if she did so, she said. When the survivor came home here in September, she narrated the ordeal to her parents following which a rape complaint was lodged with the women cell, Jha added.A case was registered against the accused under IPC sections 376 (rape) and 506 (criminal intimidation), the police officer said.The survivor’s statement was recorded before a magistrate here and the case diary sent to the Alwar police for further action, she added.“Bilaspur police have sent the complaint here. We have registered a case of sexual exploitation and initiated investigation,” SHO Aravali police station, Hemraj Meena, said.He said that they visited the ashram of the accused from where it was found that he was undergoing treatment at a private hospital in Alwar. He will be interrogated after permission from doctors, Mr. Meena said.
