kororokerokero/iStockBy MEREDITH DELISO, ABC News(NEW YORK) — More than 500 Asian giant hornets have been collected from the first known nest of the invasive species in the United States, officials announced Tuesday.Washington State Department of Agriculture entomologists discovered the nest of “murder hornets” last month in a tree in Blaine, north of Seattle, near the Canadian border.After eradicating the nest, during which the crew vacuumed out nearly 100 hornets, the entomologists removed the portion of the tree with the nest and opened it the following week to collect any hornets that had remained. The crew had pumped carbon dioxide into the tree during the nest removal to kill or anesthetize any remaining hornets, and many were still alive, officials said.Upon opening the tree, the team determined that the nest was about 14 inches long and up to 9 inches wide. Hornets in various life stages were collected, including approximately 200 queens, Sven Spichiger, the agency’s managing entomologist, told reporters during a virtual press briefing Tuesday.“As far as we can tell, we got there just in time,” Spichiger said. “We know from the literature that a small percentage of these will go on to form colonies next year, should they have been given the chance to escape.”In total, the nest contained 190 larvae, 112 worker (female) bees, nine drone (male) bees and six unhatched eggs, Spichiger said. There were 76 queen bees, and 108 capped cells with pupae, most of which were believed to be of new virgin queens.Spichiger said there is “no way of knowing” how many queens there were in total, and if any had escaped.“From accounts we have, we’re very close to having the majority of them,” Spichiger said of the queen bees, who typically produce most of the bees in a hive. “But I can’t give you an absolute, certainly, that we got every single one from the nest.”The findings from the Blaine nest come about a month after the first giant hornet was detected in the region. The agency placed live traps in the area in early October after a homeowner reported a specimen, Spichiger said.Four live hornets were caught in the traps, after which entomologists were able to attach radio trackers to three of them, and one led them to the nest — located in the cavity of a tree on private property — on Oct. 22.After the team observed dozens of hornets entering and leaving the tree, the property owner gave the agency permission to eradicate the nest and, if necessary, remove the tree, officials said.On Oct. 24, the agency announced that that the removal of the nest “appears to have been successful,” and that 85 specimens were vacuumed out of the nest.Despite this success, state entomologists believe there are additional nests in the state, based on additional specimens captured in different regions.Hundreds of traps have been set throughout Washington by agriculture department staff, scientists and others, in an attempt to eliminate the pest from the state. At 2 inches, the world’s largest hornet can kill an entire honey bee hive in just hours. With bee populations already in decline in the U.S. due to what’s known as “colony collapse disorder,” the killer hornets pose another threat to the ecosystem if they become established over several years.Agency officials say they’ll continue to keep their traps up through Thanksgiving, at which point it typically becomes too cold for the hornets to fly. But Spichiger said it’s possible they could find another nest before the end of the year, as the first hornets in the state were detected last Dec. 8.“The more people are outside and looking at this time of year, the more chances we have,” he said.Officials said the agency will continue to trap for at least three more years to ensure the region is hornet-free — and to prevent the insects from becoming a costly problem.“Just look at gypsy moths,” Spichiger said. “In the East, when gypsy moths get out of control, it costs millions of dollars. At least for long term, the smart path here is to eradicate it if we can.”The invasive species has been found as far away as British Columbia, though the “epicenter” appears to be in Washington, experts said.For humans, the giant hornet’s sting is more painful than that of a typical bee or wasp, and people are advised to use caution near the insects and not attempt to remove or eradicate nests themselves.It’s not known how the killer hornets, which are native to Asian countries including China and Japan, arrived in the Pacific Northwest, but a likely theory is that they came in via international cargo. Another less likely theory is that someone smuggled the hornets in to raise them as food, Spichiger said.“These are sought-after food items in their native range,” he said. But, he added, “I think most people don’t want to travel with such a thing.”Copyright © 2020, ABC Audio. All rights reserved.

Senegal star Sadio Mane (in green) has scored three goals so far at the 2019 AFCON Africa’s number one ranked team and 2002 AFCON runners-up, Senegal, are looking to justify their pre-tournament favourites tag by getting past Tunisia today and move one step closer to lifting a maiden Nations Cup trophy.Senegal have not reached the final since 2002 when they later went to announce themselves on the world stage with big names like El Hadj Diouf, Salif Diao, Henri Camara and more at the Korea Japan World Cup.However that golden generation never won the Nations Cup, a quest Sadio Mane and co are eager to rectify. Aliou Cisse who was captain of the 2002 team is now manger of a Senegal team that impressed at the 2018 World Cup but crashed out at the group stage due to an inferior disciplinary record to Japan.Senegal have been impressive in the tournament so far, winning four of their five matches and conceding just a single goal to Algeria, and are considered favourites against the Carthage Eagles.Tunisia had drawn all four of their games in 90 minutes before knocking out minnows Madagascar in the quarter-finals to book their place in the last four for the first time since 2004.In recent years there has been little to chose between these two sides with the last six encounters bringing two wins for Tunisia, one victory for Senegal, and three draws.It was the Senegalese who won the most recent encounter, a 2-0 group stage win in the 2017 edition of the tournament.Tunisia striker Wahbi Khazri recovered from a thigh problem to start the quarter-final win against Madagascar and should once more start. Liverpool forward Sadio Mane has been Senegal’s most dangerous player and will lead their attack once more today.The last eight saw Senegal overcome a stubborn Benin side 1-0, and the semi-final could play out in similar fashion for Cisse’s men. Indeed, the Lions of Teranga have been faced with defensive opponents throughout the tournament who have invited them to break them down, and Senegal have more often than not eventually found a way through.Five of the seven goals they have scored in the tournament have come in the second half, with three of their five matches being goalless at the break.Share this:FacebookRedditTwitterPrintPinterestEmailWhatsAppSkypeLinkedInTumblrPocketTelegram
DES MOINES — The Government Oversight Committee in the Iowa House will meet March 16th to hear from the state agency director Governor Reynolds has put in charge of changes at the state-run Glenwood Resource Center.Department of Human Services director Kelly Garcia started in the job November 1st and 21 days later the U.S. Department of Justice announced it was investigating allegations of the disabled patients at Glenwood were being mistreated and being subjected to human experiments.House Speaker Pat Grassley, a Republican from New Hartford, says enough information has been made public that the committee can have a productive meeting without jeopardizing any investigation.“We weren’t just going to hold a meeting to say we held a meeting,” Grassley says.Grassley credits the DHS director for meeting with the families or guardians of the patients at Glenwood as well as staff and for notifying key legislators of changes she’s making at the facility. Grassley says next month’s hearing will give Garcia a chance to address a larger audience.“One individual hasn’t had the chance to sit down with every single legislator to show the reaction that’s happened,” Grassley says.Earlier this week Republicans and Democrats in the Iowa Senate unanimously confirmed Garcia to serve as director of the Department of Human Services.
Four England internationals – led by brilliant play from Hayley Davis – have qualified for the top competition in US women’s college golf. Davis will be joined by Bronte Law, Charlotte Thomas and Meghan MacLaren at the NCAA Division 1 championship at the Concession Golf Club in Bradenton, Florida from May 22-27. Davis (Ferndown/Baylor University) won her regional qualifier in Texas in tremendous style, scoring a 16-under-par aggregate of 200 (67-68-65). She was five shots clear of Law (Bramhall/UCLA), who is currently ranked fourth in the world, and had rounds of 68-68-69. Thomas, who is based in Singapore and studies at the University of Washington, tied 10th on three-under. Davis (image © Leaderboard Photography) became the first-ever Baylor University player to win an individual regional title and fired a school-record score. Her final round of seven-under 65 tied her own college record for the lowest tournament round. Meanwhile, Meghan MacLaren (Wellingborough/Florida International) tied seventh in her regional in Utah, to earn her place in the national championship. She scored seven over with rounds of 72-77-71. All four internationals are winners on the US women’s college circuit. MacLaren, the British stroke play champion, has seven titles; Davis, the English stroke play champion, and Law, the English amateur champion have both won three times; Thomas, a past winner of the English mid-amateur title, has won twice. 13 May 2015 Hayley leads quartet into USA finals
One of the biggest and most infamous rumors in the modern history of the NBA is that former Cleveland Cavalier Delonte West had slept with ex-teammate LeBron James’ mother, Glorida James. The rumors ran rampant during King James’ final season in Cleveland in 2010 before he took his talents to South Beach to play for the Miami Heat.While the innuendos were never confirmed and the parties involved vehemently denied the alleged romantic affair back then, James’ play during that playoff loss against the Boston Celtics was so anemic that many people believed there was something to the rumors.Ironically, now that LBJ has taken his talents back to Cleveland, the rumors would arise once again. In an interview with Vice Sports, West seems to confirm that he indeed had sexual relations with Gloria James.In a wide-ranging interview, West asked about why he didn’t name his son Delonte Jr:“I named my son Cash after Cashius Clay and Johnny Cash…His middle name is Delonete but I didn’t want to name him Delonte West Jr. just because of that… I don’t want my son going to school and people making fun of him for something his daddy did, “Oh didn’t yo daddy have sex with LeBron James mama?’ Man, I don’t want to deal with all that . . . “Well, that looks like confirmation to us. What do you think? Do you believe that he committed the unthinkable act and that this was a confession?

By John BurtonKids volunteer at FH Firemen’s Fair for a ticket to rideJoe Perrotto (right), who oversees these fair volunteers, with his recruits.FAIR HAVEN – Getting up early on a hot and humid late August morning to shuck corn may not be everybody’s idea of fun. But for the kids volunteering their corn-husking talents for the Fair Haven Firemen’s Fair, it seemed like a lot of fun – and there was a payoff for their labor.“My mom said you can work at the fair and get free (ride and meal) tickets,” 13-year-old Cameron Reed said.“It sounded pretty cool, so I decided to come do it,” offered Jake Robinson, Cameron’s cousin, also 13, who was visiting from Somerset.Cameron and Jake were two of about 10 kids on hand standing over trash cans on Tuesday, Aug. 28. They were pulling ears of corn out of tall sacks and stripping them of their husks and silk so they could be cooked later that day when the crowds arrived at the fire company property at 645 River Road.“I’ve been doing this since, like, third grade,” Cameron said. “It’s not that bad.”This is the second year that borough residents T.J. Sullivan and James Foley, both 12, have offered their help, which includes doing some chores in addition to corn duty, for the annual fair.“I like it,” T.J. said, with James nodding in agreement.They have been attending the fair – which opened Aug. 24 and closes Sept. 1 – most of the evenings, so, they said, it seemed appropriate that they offered their help. It was a decision supported by their parents.The boys also liked the idea of getting those extra tickets. James said he could get either two free rides and a meal or two meals and a ride with the tickets earned volunteering. He decided he would go for the two rides, probably The Zipper.“Definitely, The Zipper,” jumped in 10-year-old Lily Barnett. “It’s so spinney and fast.”Lily was less enthusiastic about spending her morning shucking corn and doing other chores. “But it’s worth it when I get tickets,” she said.“I like the rides and the boardwalk games,” said William Francis, 9, who was working alongside Jake and Michael Jakub, two brothers who are 11 and 9, respectively. But for William there was another draw beyond the rides and fun at the fair that the other kids all noted as well. “You get to see your friends here,” he said.“It’s a good way to meet up with friends you haven’t seen over the summer,” T.J. agreed.People who were away for much of the summer, James said, seem to make it a point to return for this end of the season tradition. “Pretty much all of Fair Haven goes.”James also saw another benefit to his volunteering at 8 a.m. “Now, at least when you go back to school,” he said, “it’s not so bad getting up in the morning.”Joe Perrotto, a 20-year veteran of the fire company who was on hand to oversee the kids and their work, is responsible for purchasing and morning organization for the fair. Traditionally, he said, he gets 15 to 30 kids each year to participate and over the years he’s seen many return year after year.“You watch them grow up and the next thing you know, they’re riding the fire truck,” as fire company members, he said. “This is their way to give back.”“Without these kids, we couldn’t do what we do,” he said. “They do the chores to get us going.”It’s not all fun and games either, he admitted. “One of the things with these kids here is they have to put up with me for eight days.”

Always look into the methods used when scientists speak confidently about models for making things appear out of nowhere.News from Comet 67PSurprise discovery suggests ‘gentle’ start for Solar System (BBC News): “The discovery has come as a complete surprise to scientists who thought that oxygen would have reacted with other elements as planets were forming,” declares the normally overconfident BBC reporter Pallab Ghosh. “The results indicate that current ideas about how our Solar System formed may be wrong.” See paper in Nature, “Abundant molecular oxygen in the coma of comet 67P/Churyumov–Gerasimenko.”Modern Mystery: Ancient Comet Is Spewing Oxygen (Space.com): More about this “big surprise”:What’s mystifying astronomers about the new find is why the oxygen wasn’t annihilated during the solar system’s formation. Molecular oxygen is extremely reactive with hydrogen, which was swirling in abundance as the sun and planets were created. Current solar system models suggest the molecular oxygen should have disappeared by the time 67P was created, about 4.6 billion years ago.Discovery of molecular oxygen in comet tail forces us to rethink how the solar system formed (Christian Schroeder in The Conversation): Molecular oxygen has a ripple effect on models of the whole solar system: “That means that our solar system might have formed from an unusually warm cloud, which raises the question as to what might have caused this elevated temperature.” Other possibilities are bandied about. Schroeder puts a happy face on falsification: “We can look forward to the next surprises this comet has in store for us.”Rosetta Mission: Ptolemy sniffs next piece of the comet puzzle (Science Daily): Ptolemy is one of the instruments on the spacecraft. It detected ice and CO2, but very little CO that was predicted. “Our results, from Comet 67P’s surface, has both surprised us as well as opened up a variety of new questions about how comets form and how they work.”Rosetta scientists unveil the source of ice and dust jets on comet 67P (Monica Grady in The Conversation): The comet is darker than it’s supposed to be. The expectations were all wrong. “But despite this wealth of visual evidence for researchers there is a lot we still don’t know about the comet – including why it is covered in organic material rather than just ice and what causes its powerful jets of dust and ice.”Planet ModelsNow that we have seen that scientists can be surprised at how wrong their models are, let’s see some new models they’re promoting with hubris.Growing the terrestrial planets from the gradual accumulation of submeter-sized objects (PNAS): Veteran planet-maker Hal Levison is at it again, cooking up planets out of dust. This paper is filled with assumptions, conveniently-chosen initial conditions, and leaps of faith, such as assuming dust grains will form pebbles without getting swept into the sun or blown out the disk. But it sure got nice coverage in the press.Why Earth is so much bigger than Mars: Rocky planets formed from ‘pebbles’: New process explains massive differences between Earth and Mars(Science Daily): Typical uncritical press coverage of the new Levison model. Gives the wizard the last word: “As far as I know, this is the first model to reproduce the structure of the solar system — Earth and Venus, a small Mars, a low-mass asteroid belt, two gas giants, two ice giants (Uranus and Neptune), and a pristine Kuiper Belt,” said Levison.”Astrophysicists find Jupiter likely bumped giant planet from solar system (PhysOrg): Explaining the position of Uranus and Neptune requires a game of billiards with Jupiter and Saturn. Nobody saw a mythical fifth planet that was conjured up to get a new model to work. Conveniently, Jupiter ejected it without leaving a trace.Star Models‘One size fits all’ when it comes to unravelling how stars form (PhysOrg): Positivist coverage of interpretations of blurry images from a Chilean telescope. Article claims big stars form the same way as their models say small stars form.Whoops, what about these? Models are only simulations of reality. Reality is often more complex, e.g.: Astronomers find disk of young stars near center of Milky Way (Nature): “The discovery suggests there has been a constant supply of young stars to the galactic center, but where do they come from?” Daniel Clery asks. “The galactic center is thought to have used up its supply of gas from which to make stars long long ago, so astronomers will have to figure out some mechanism by which young stars are moved inward from farther out in the galaxy.” Aren’t there other possibilities? (1) Maybe they’re misclassifying young and old; or, (2) Maybe the galaxy isn’t as old as they think it is.Astrophysics: Primordial stars brought to light (Nature): This optimistic article claims a possible success in the hunt for Population III stars, theoretical stars made out of pure hydrogen, with traces of helium and maybe lithium. That’s the only kind of star that could have formed after the big bang when those were the only elements.Twinkle twinkle little star, I know exactly what you are;For by spectroscopic ken, I know that you are hydrogen.All the other elements had to form from supernovas, the story goes. Anyway, a certain galaxy seems to have “candidate” Population III stars, but they are mixed in with heavy-metal stars if that’s what they are. The observations appear to be model-dependent. “The authors find that the observations of CR7 are best explained by a hybrid stellar population containing both young, metal-free stars and an older, chemically evolved population, respectively emitting most of the UV and optical light,” reporter Bethan James writes.Galaxy and Cosmology ModelsMissing gravitational waves lead to black hole rethink (PhysOrg): Another upset reported. “Human understanding of galaxies and black holes is being called into question after an 11-year search for mysterious gravitational waves—famously predicted by Albert Einstein 100 years ago—failed to find anything.”New theory of stealth dark matter may explain universe’s missing mass (Science Daily): All of the above is only a model for 5% of reality, astronomers think. They’re still looking for the other 95%. Maybe it’s just “stealthy” like a ghost—a timely idea for Halloween.Birth of universe modelled in one of largest cosmological simulations ever run (Science Daily): It’s not clear what the guys at Argonne National Labs are doing spending taxpayer dollars to run computer simulations on cosmology for the Department of Energy, but they have a zinger. They got stars and galaxies to form against their will out of a uniform fog after the big bang by mixing in copious amounts of lucky charms called dark matter. For those who would like to see an honest skepticism of these models, see Spike Psarris’s video, What You’re Not Being Told about Astronomy, Part II: Stars and Galaxies. He quotes leading astronomers who reveal that they don’t know what they are talking about. They have to invoke the Tooth Fairy twice (dark matter and dark energy), one embarrassed astronomer confesses. If stars and galaxies didn’t exist, they would be happy to explain why this is exactly what they expect, another says.Science is the only career where you can be totally wrong and still keep your job and enjoy a great reputation in the media. The way you keep going is to look excited and glad about the fallen expectations, hyping the promise that the puzzle opens up new possibilities for better models. Now that you have seen the difference between hubristic models and reality, try your hand at interpreting these articles:How we plan to bring dark matter to light (PhysOrg)Dark matter universe (PNAS)Have physicists seen the dying flash of dark matter? (Science)X-ray signal from outer space points to dark matter (Science)Our Universe: It’s the ‘Simplest’ Thing We Know (Live Science)Evolution of the universe in unmatched precision (Science Daily): “New most comprehensive hydrodynamical simulation of the universe’s visible structure”New precise particle measurement improves subatomic tool for probing mysteries of universe (PhysOrg)Recommended reading: “The Scientific Method Is a Myth” by Daniel P.
