Video: How to make a square snowflake

first_imgIf you zoom in on a snowflake, you’ll see its six-sided symmetry mirrored at the molecular level. As water freezes, its molecules typically arrange themselves in a repeating pattern of hexagons, the geometry that forms the snowflake’s star-shaped structure. Now, scientists have created a new type of ice they call “square ice,” which forms a cube-shaped pattern instead, with water molecules arranged in neatly aligned rows. Scientists formed these crystals—which occur at room temperature—by squeezing tiny amounts of water between two sheets of graphene, planes of carbon a single atom thick. Van der Waals forces cause the carbon atoms in the two sheets to attract, squeezing nanometer-thick puddles of water inside a high-pressure graphene sandwich. The scientists imaged the crystals with high-resolution electron microscopy and found that the unique environment made the ice crystallize in a new, cubic configuration, they report online today in Nature. The crystals rearranged themselves as scientists imaged them, but remained in an ordered structure, as shown in the video above, in which dark spots indicate the position of water molecules. The crystals split and merge over a period of 4 minutes, which is sped up in the video. The result could be useful for understanding the movement of water when squeezed inside tiny channels, for instance, in carbon nanotubes or cell membranes. And if these crystals formed on a larger scale, they would make square snowflakes, instead of six-sided ones.(Video credit: Courtesy of the University of Ulm [Germany])Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)last_img read more

Scoreboard in Brazil Shows 0.8-0 After a Goal is Scored. Here is Why

first_imgBrazilian women’s football set an attendance record on Saturday with more than 28,000 fans at the Arena Corinthians stadium to watch the second leg of the Sao Paulo state championship final.Corinthians beat local rival Sao Paulo 3-0 in front of 28,862 fans with match tickets had been given out for free during the week. The previous record was in 2017 at Manaus’ Arena Amazonia in the semifinals of the Brazilian championship when Iranduba lost 2-1 to Santos in front of 25,371 people. But that was not all. The game on Saturday grabbed the attention of the world for something rather unique.Instead of the scoreline reading 1, to denote a goal scored, it showed 0.8. The reason — to highlight the pay discrimination or wage gap in Brazil.According to recent research, women in Brazil earn 20 percent less than men for doing the same work. The scoreline was a small way to remind people that.The scoring pattern continued, as the scoreboard read 1.6-0 for the second goal and 2.4 for the third.The move was part of an initiative from Paulista Football Federation (FPF) with the UN Women and the advertising agency BETC.Corinthians won the Sao Paulo state championship final having won the first leg 1-0.

I hope to see Messi win a title with Argentina: Puyol

first_imgNew Delhi, May 16 (PTI) Spanish football legend Carles Puyol is hoping to see his long-time Barcelona teammate Lionel Messi win a silverware with Argentina in the near future, something that has eluded him for long. Many believe that the Argentine magicians legacy is incomplete without a World Cup triumph — undoubtedly the biggest title on the international stage. World Cup-winning skipper Puyol is in India to promote the upcoming FIFA U-17 World Cup. “The one thing about Messi is that he keeps improving and he has been consistent for 10 years, he keeps getting better and thats because he has the drive, the passion. “I hope Messi wins something with his national team and not only with his club, then he would have won everything with everyone,” Puyol said during a facebook live session today. Messi has led Argentina to a major final in each of the last three summers but remains without a title after falling short at the 2014 World Cup, 2015 Copa America and 2016 Copa America Centenario. The 39-year-old Puyol has no doubt that Messi is ahead of Cristiano Ronaldo. “For me the best is Messi, I have played with him. Messi has given me a lot of joy. I would say both are great players, their competition is very intense and it helps them to keep getting better, and not get complacent. “Cristiano is one of the greatest in football history, but Messi is better.” Asked about India hosting its first FIFA event, Puyol said it will definitely generate a lot of interest in the country. “Its a great step forward hosting the U-17 World Cup. This is where the future stars start their development process. “India is like a young football country in that sense but it has been going growing rapidly. Indian fans are passionate and I am sure that the World Cup will generate something much, much bigger in India and then more people will get introduced to the game.” When asked how India could aspire to improve its standing in international football, Puyol said its important that kids get introduced to the sport at a very young age and enjoy the practice sessions. “The important thing is to start early and practice, practice, practice, have the passion and enjoy the game. One should not think professional at that stage. This is the greatest sport in the world and you can have a lot of fun playing it.” While he has been a part of many a triumphant campaigns with Barcelona, Puyol has a special place for the Champions League triumph in 2006. “Champions League 2006 final has a special place in my heart because it was the only game my dad, who is no more, watched me live. Of course, it was also the first Champions League title triumph with Barcelona, but it also has a very emotional connect.” He said he was lucky to have played alongside some of the best players of the world and rated Gerard Pique as the best centre-back in the world. “At this point of time Gerard Pique is the best in the world. It is a very difficult thing to come to Barcelona and perform in that particular position and also Javier Mascherano. “In the youth system of Barcelona there are amazing players who will represent Barcelona in the future.” PTI AH CM CMadvertisementlast_img read more

Mauricio Pochettino should manage Manchester United if not Solskjaer, says Wayne Rooney

first_imgManchester United caretaker manager Ole Gunnar Solskjaer deserves the chance to take over as permanent boss while Tottenham Hotspur’s Mauricio Pochettino is be the best alternative, according to former club captain Wayne Rooney.Solskjaer replaced Jose Mourinho in December and has guided United to seven wins and a draw in the Premier League to make a compelling case for his appointment ahead of early bookmakers’ favourite Pochettino.The Norwegian has helped United go within two points of the top four while also reviving a free-flowing style of soccer that had gone missing under Mourinho.”It’d be nice to see Ole Gunnar continue with this form and get a shot at the job on a permanent basis,” Rooney, United’s all time record scorer, told CNN World Sport in an interview.”But if not, if the club go to choose from somewhere else, then I think Pochettino would be the right guy.”Pochettino has previously said he was fully committed to delivering results in his current job but that has done little to quell speculation about his future at Tottenham.The Argentine, who joined Tottenham from Southampton in 2014, has guided the London club to consecutive top-three finishes in the league, but he is yet to win a trophy.Solskjaer said last week the owners of Norwegian club Molde, who sent him to Old Trafford with their blessing, had asked him to try to turn his temporary stint into a permanent role.United are expected to make a decision on their manager at the end of the season.advertisementSolskjaer’s side face Fulham in the league on Saturday.Also Watch:last_img read more

Rohit Sharma: The King of T20 Internationals

first_imgAfter winning the world over with an unprecedented 5 centuries in the World Cup 2019, Indian opener Rohit Sharma, on Sunday claimed a slew of T20I records placing him at the summit of the shortest format statistics pile. On his way to a match-winning 67 off 51 balls against West Indies in the 2nd T20I in Florida, Rohit Sharma claimed the one major T20I record which he didn’t own till then – maximum career sixes in the format.Rohit surpassed Chris Gayle as the batsman with the highest number of sixes in T20Is (107 in total). He already held the record for the most runs, centuries, boundaries and 50+ scores in T20Is. The latest achievement surely means that Rohit Sharma can now claim to be the undisputed King as far as T20Is are concerned.In 96 T20Is, Rohit leads the way with 2,422 runs with Indian captain Virat Kohli following him close on 2,310 runs. New Zealand’s Martin Guptill rounds up the top-3 with 2,272 runs to his name.On the list of cricketers with most centuries in T20Is, Rohit tops the charts with 4 100s followed by Glenn Maxwell and Colin Munro, who have hit 3 centuries each for Australia and New Zealand respectively.Rohit’s knock of 67 on Sunday also helped him topple Kohli as the batsman with most fifty-plus scores in T20Is. Rohit now has 21 such scores as compared to Kohli’s 20, who is yet to score a century in the shortest format of the game for India.Even though Kohli has hit the most number of 4s (225) in T20I history, Rohit sits at the top once you consider the total number of boundaries (4s + 6s). With 215 fours and 107 sixes, Rohit’s boundary tally of 322 is miles ahead of the rest with only Guptill (303) coming close to the maverick opener.advertisementRohit will have another chance on Tuesday to boost his numbers even further when India and West Indies face off in the 3rd and final match of the series in Guyana.Also Read | India vs West Indies: Rohit Sharma breaks Chris Gayle record for most sixes in T20IsAlso Read | 2nd T20I: Rohit Sharma, Krunal Pandya star as India beat West Indies to take unbeatable series leadlast_img read more

Newfoundland and Labrador government to cover abortion pill as of Sept 1

first_imgST. JOHN’S, N.L. – The Newfoundland and Labrador government says it will cover the abortion pill as of Sept. 1, putting it in line with six other Canadian provinces that already provide the medication free-of-charge.The province announced in a statement Wednesday that it will provide universal coverage for Mifegymiso, an alternative to surgically induced abortions, to residents holding a valid health card.“Individuals in this province are entitled to abortion, which is a legal, medical service,” said John Haggie, Minister of Health and Community Services, in a news release.“Universally covering the cost of this alternative to surgical abortion will ensure people continue to have safe and unimpeded access to this health service.”The two-drug combination terminates pregnancies of up to nine weeks and will have to be prescribed by a health-care professional. As well, the release said an ultrasound will have to be performed, in order to confirm the gestation period, before Mifegymiso is prescribed.The announcement came as welcome news to Frederique Chabot, director of health promotion with Action Canada for Sexual Health and Rights, a national organization aiming to advance sexual and reproductive rights in Canada.“To continue to see provinces taking leadership and addressing historical gaps in access for their residents is absolutely great news,” said Chabot in a phone interview from Ottawa.She said since the drug was rolled out in 2017, British Columbia, Alberta, Ontario, Quebec, Nova Scotia and New Brunswick have already committed to universal coverage for Mifegymiso for their residents. Up until Wednesday’s announcement, Newfoundland and Labrador was the only province that did not at least provide partial coverage of the pill.Although abortion in Canada was decriminalized decades ago, Chabot said access to services have been distributed unevenly across the country, with some rural communities — like much of Newfoundland and Labrador — left behind.“So in Toronto, you’ll have access to state-of-the-art care, you’ll have access to multiple options, to clinics, to hospital care,” she said.“But in rural or remote areas anywhere in the country, access is very poor and absent.”She said people in areas where abortion services are inaccessible may have to pay out of pocket to travel to places where they can get the services they need, taking them away from their communities and support systems.“Depending on your postal code or what’s in your bank account, you either had access to health care or you didn’t,” said Chabot.Chabot said Mifegymiso is as safe as a surgical abortion and is the World Health Organization’s gold standard for medical abortion, so access to the pill helps fill some of the gaps left by spotty access to abortion in rural communities.The announcement came two months after medical students and practitioners in the province wrote an open letter to the premier and Health Department asking for universal Mifegymiso coverage, as well as supportive resources for physicians prescribing the drug.In a release, students who worked on the letter applauded the announcement.“Removing the cost barrier to medical abortion in primary care will ensure that persons living in rural and remote communities throughout Newfoundland and Labrador have more equitable access to an essential medical service,” said Maggie O’Dea and Chris Vizena of the Memorial University Medical Students’ Society.“This announcement represents a true advancement of reproductive rights to which we are proud to have contributed.”Prince Edward Island is now the only Atlantic Canadian province without universal Mifegymiso coverage, although the drug is covered under both the UPEI and Holland College student health-care plans.— By Alex Cooke in Halifaxlast_img read more

Airbus to stop making struggling A380 superjumbo in 2021

TOULOUSE, France — European aviation giant Airbus says it will stop making its superjumbo A380 in 2021 after struggling to sell the world’s biggest passenger jet.Airbus said in a statement Thursday that Emirates is cutting back its orders for the plane and as a result “we have no substantial A380 backlog and hence no basis to sustain production.”The decision is a boon for rival Boeing and a blow for Airbus. Airbus had hoped the A380 would squeeze out Boeing’s 747 and revolutionize air travel as more people take to the skies.Instead, airlines have been cautious about committing to the costly plane, so huge that airports had to build new runways and modify terminals to accommodate it. The double-decker planes started flying in 2008 and seat more than 500 passengers.The Associated Press read more

Turkmenistan reaches goal of universal salt iodization UNICEF says

UNICEF Regional Director for Central and Eastern Europe Maria Callvis gave an award to the Turkmen Government for reaching the universal salt iodization (USI) goal already reached by Bhutan, the former Yugoslavian Republic of Macedonia and Panama.”USI is the most effective way to protect children from iodine deficiency – the world’s leading cause of preventable mental retardation and brain damage. So this award is a major milestone for Turkmenistan. This is the first country in Central Asia – and only the fourth country worldwide – to reach this target,” Ms. Callvis said.UNICEF provided technical support to the programme for about 10 years and the United States donated $200,000, UNICEF said. read more

Developing countries help to spur rising global investment – UN report

Total FDI soared by 29 per cent last year to $916 billion, the second consecutive rise, and the highest since the record year of 2000, the UN Conference on Trade and Development (UNCTAD) said in World Investment Report 2006. A jump in cross-border mergers and acquisitions was largely responsible as many companies enjoyed stronger profits and more buoyant stock markets.Developed countries still attracted the majority of FDI ($542 billion), but developing nations now account for a record $334 billion and some of the highest rates of growth were recorded in West Asia (85 per cent) and Africa (78 per cent). South, East and South-East Asia also registered hefty increases. FDI out of developing or transition economies also rose by 5 per cent to $133 billion.Anne Miroux, head of the UNCTAD team that produced the report, said after its release that developing economies had strengthened their global position last year.“A number of TNCs (transnational corporations) from developing countries are emerging as major players on the world stage – and they are here to stay,” she said. “This represents a profound change in the global economy and will have substantial consequences for international economic and political relations.”The report’s authors said they expect the trend of rising investment to continue in developing countries rich in natural resources because of higher prices for many commodities.Banking, telecommunications, real estate and other services drew the greatest investment, but the natural resources sector – especially petroleum – experienced the highest rise.Introducing the report, UNCTAD Secretary-General Supachai Panitchpakdi said the current growth is notable for being so broad-based, with investment inflows increasing in 126 economies.The United Kingdom was the overall largest recipient country, thanks to the merger of Royal Dutch Shell of the Netherlands and Shell Transport and Trading Company of the UK last year. The United States was second and China placed third. read more

Ohio State womens volleyball pushes No 5 Washington to 5 sets but

OSU junior defensive specialist Valeria León (3) during a game against Robert Morris in the NCAA tournament on Dec. 4 at St. John Arena. OSU won 3-0. Credit: Samantha Hollingshead | Photo EditorFor the first time in 14 matches, the No. 5-seeded Washington women’s volleyball team was on the verge of losing, as No. 12 Ohio State forced a fifth set.Despite a gritty effort, however, the Buckeyes couldn’t pull off the upset, falling in the back-and-forth Sweet 16 matchup (23-25, 25-20, 25-18, 12-25, 15-8) in Lexington, Kentucky.The Huskies extended their winning streak to 14 and will advance to the Elite Eight to face fourth-seeded Nebraska on Saturday.Against a Washington squad that leads the country in hitting percentage, OSU was able to turn the match into a defensive battle. Even in defeat, the Buckeyes outhit the Huskies, .179-.154, and out-dug them 75-60.“It was the kind of match we wanted,” coach Geoff Carlston said. “We really wanted a brawl. It was a defensive battle. I was really, super proud of our team.”Freshman setter Taylor Hughes and junior middle blocker Taylor Sandbothe led the effort on defense. Hughes added to her 44 assists with a career-high 22 digs and five blocks, while Sandbothe had eight blocks despite battling an illness that clearly took its toll.OSU held senior middle blocker Lianna Sybeldon — the nation’s leader in hitting percentage — to a .206 clip, though she still led Washington in kills with 14. Sybeldon added six blocks to give her a team-high 17 points.Senior middle blocker Melanie Wade was the Huskers’ most efficient hitter, posting a .406 hitting percentage with 10 kills and only one error.For OSU, Elizabeth Campbell was the driving force on offense, leading all players with 24 kills — including 18 over the final three sets. The senior outside hitter finished one away from her career-best mark of 25, which she set during her time at Duke.In the first set, the Scarlet and Gray hit only .070 and had five service errors but held the proficient Washington offense to a minus-.024 hitting percentage behind seven blocks, including five from Sandbothe.“The first set was indicative of what the match was going to be,” Carlston said. “It was pretty obvious it wasn’t going to be an easy match by anybody.”Neither team led by more than three points in the opening frame, but OSU was able to fend off the Huskies, giving them only their fifth loss in a set during their winning streak.But Washington got back on track in the second and third sets, shooting a combined .277 as the Buckeyes could muster only one block after their big performance in the opening frame.Faced with defeat in fourth, OSU buckled down and handed Washington its worst loss in a set this season. Once again, the Huskies had a negative hitting percentage (minus-.059) as the Buckeyes registered four more blocks.Although it had lost its momentum, Washington couldn’t be stopped in the fifth set. The Huskies didn’t make a single error, hitting .571 to end OSU’s upset bid.“Congrats to Washington,” Carlston said. “They made great plays, especially (in) the fifth set. We just weren’t able to get a rally going.”Aside from Campbell, three other seniors played in their final collegiate game. Middle blocker Tyler Richardson had six kills and four blocks (three solo), outside hitter Katie Mitchell sent home seven kills and setter Emily Ruetter picked up six assists. Middle blocker Andrea Kacsits did not appear in the contest.“As far as our four or five years are concerned, we have had memory after memory and it’s because of awesome people that we were surrounded by,” Kacsits said.OSU finished the season with a 25-10 record, tying its best mark under Carlston during his eight years in Columbus.“So thankful for this group and the opportunity to be here,” Carlston said. “It hurts, but in the locker room I told our team the feelings we have and the emotions in that room was a really unique experience. I wanted them to take a moment and get some perspective on it because it’s pretty cool.” read more

Radical genome recoding paves way for new era in the manipulation of

first_imgThere’s a lot of hyperbole in science journalism, or at least a tendency to state every finding in its most extreme possible form, so let’s be clear: the following story is incredible, a fundamental step forward for the human animal and its ability to control the environment in which it lives.This isn’t an over-blown test tube victory unlikely to generalize to humans; this is a proof of concept for a whole new era in the manipulation of life. In two concurrent studies published last week in the journal Science, researchers recoded the genomes of e. coli colonies to begin to use building blocks never before seen by living things.Proteins, the main functional units of the cell, are made of up of various combinations of 20 basic amino acids. Since DNA uses a four-letter system to code for these amino acids, basic math can show us why life was forced to use DNA words (or “codons”) three letters in length: One letter can code for four different states, two letters for (4*4 = 16) different states, and three letters for (4*4*4 = 64) different states. Two letters isn’t quite enough, but three provides many more possible words than the 20 we technically require.The genetic code. Notice how many amino acids can arise from more than one 3-letter codon.As a result the body has what are called “degenerate codons,” meaning that two different codons could both lead to the same final amino acid. In the first of these two studies, researchers replaced the codon UAG, which normally acts as a “STOP” signal that marks the end of protein synthesis, with the codon UAA. UAA serves the same STOP function as UAG, which basically means that the researchers can remove the STOP functionality from UAG codons without harming the cell. They have freed up one out of the cell’s 64 words with little or no impact on that cell’s ability to survive.These genetically recoded organisms (or GROs) now have a word free — but there’s no need to stop at just one. The second of the two studies looked to test the bacteria’s ability to soak up multiple recodings, choosing 13 different codons to replace with degenerate versions. The results were incredible, as even with 24% of the relevant DNA replaced, the proteins of interest were still made without trouble. That’s a full fifth of the protein vocabulary now open for some alternate use, and the possibilities are nearly endless.Non-Standard Amino Acids (NSAAs) can now be incorporated into proteins by inserting new instances of the hijacked codons. In the first study, any time the researchers inserted the former STOP codon UAG, the cell incorporated their new UAG NSAA into the growing strand. This means they’ve expanded the protein alphabet from 20 amino acids to 21. Beyond any possible uses for this extra building block, it turns out that such changes to biochemistry can have benefits in and of themselves.Radical recoding boiled down to its bare essentials.Even just a single codon replacement made the colony of the first study much more resistant to viral infection. Viruses generally work by hijacking a cell’s machinery to make more copies of the virus, and so their life cycle depends on finding predictable genetic mechanisms with which to work. Changing the meaning of codons and substituting NSAAs fundamentally hampers the main mechanism of viral replication. This could make industrial bacterial colonies, which will only become more important as time goes on, all but invulnerable to the sorts of catastrophic viral invasions that currently keep industrial biologists awake at night.The NSAAs themselves could allow amazing new advances, as well. More durable versions of amino acids, or novel stabilizing molecules, could lead to drugs that survive longer in the body, or which have much longer expiration dates than today’s versions. Totally new lock-and-key molecules could be added to make sure a drug can’t be delivered to the wrong part of the body. Stretches of a suicide molecule could let scientists destroy just a single type of engineered protein at will.This is the first time we have managed to successfully monkey with the genetic code itself, completely redefine a DNA word across an entire genome. It’s an important step forward for synthetic biology, and a powerful research method that is certain to prompt many a Geek article still to come.last_img read more

Sunny Isles Beach Marshalls evacuated after reports of armed man

first_imgSUNNY ISLES BEACH, FLA. (WSVN) – Reports of an armed man inside the Marshalls in Sunny Isles Beach prompted an evacuation of the store.Sunny Isles Beach Police units responded to the store near Sunny Isles Beach Boulevard and Collins Avenue, at around 8:40 p.m., Sunday.Officers evacuated the store and surrounded the building. A Miami-Dade Police chopper and K-9 units assisted in the search.A witness who identified himself as Alex described the tense moments.“There was some banging, but I don’t know what it was. It was probably a shot. I don’t know,” he said.Police said they did not find an armed subject in the store. They said he may have left before they got there.“It’s a crazy day. Nothing like it, you know. This is typical in Florida, always happens,” said Alex. “I heard last time it was over here, in the other building but nothing major. You just gotta be protected at all times. That’s it.” No one was taken into custody.Copyright 2019 Sunbeam Television Corp. All rights reserved.

Critics Question Sealaska Ballot

first_imgFour Sealaska board of directors candidates say the regional Native corporation’s balloting process violates a recent court ruling.Sealaska says it’s not a problem.Sealaska Plaza, the corporation’s headquarters.The Alaska Supreme Court decision came in a case involving CIRI, the regional Native corporation for the Cook Inlet area.The group 4 Shareholders for Sealaska says Native corporations must now disclose how discretionary votes will be counted in board elections.Discretionary votes are turned over to the board, which casts them for its slate. Shareholders authorize such voting by checking a box on their ballots, also called proxies.Randy Wanamaker is spokesman for the 4 Shareholders group.“Sealaska’s proxy does not contain that language. They have some language in their proxy booklet, but not on the proxy itself. And the state Supreme Court said you must put it on the proxy,” Wanamaker says.Sealaska officials say election attorneys have reviewed the issue.Corporate Secretary Nicole Hallingstad says the ballots are legal, as-is.“The outside group misinterprets the CIRI case and is designed to confuse shareholders. Sealaska’s proxy statement, proxy card and bylaws all state clearly that discretionary votes will be allocated to elect the board slate candidates,” Hallingstad says.Thirteen people are seeking four seats on the regional Native corporation’s board. There are three incumbents, the four-shareholders slate and six independents.This year’s proxy also includes a resolution to limit discretionary voting.Balloting is underway and winners will be announced at the June 28th annual meeting near Seattle.Sealaska is the regional Native corporation for Tlingits, Haidas and Tsimshians with roots in Southeast Alaska. More than half its almost 22,000 shareholders live outside the region.The 4 Shareholders candidates are Karen Taug, Ross Soboleff, Carlton Smith and Margaret Nelson.The independent candidates are Myrna Gardner, Mick Beasley, Michelle McConkey, Will Micklin, Edward Sarabia Jr. and Ralph Wolfe.The board incumbents are Sidney Edenshaw, Ed Thomas and Rosita Worl. Incumbent Bryon Mallott is not seeking re-election so he can focus on running for governor.Sealaska4′s press release:Based on a recent Alaska Supreme Court decision, the four independent candidates for the Sealaska board – Karen Taug, Ross Soboleff, Carlton Smith, and Margaret Nelson — are questioning the rules governing Sealaska’s annual meeting voting process.“It appears Sealaska failed to make changes to this year’s corporate ballot as required by a recent Alaska Supreme Court decision,” said the group’s spokesman, Randy Wanamaker. “On the advice of counsel, the Sealaska4 sent letters on May 22 to Sealaska’s corporate secretary and the independent inspector of elections. The correspondence pointed out Sealaska’s failure to properly disclose how discretionary votes will be distributed.”Two weeks later, the Sealaska4 candidates have not received a response nor has Sealaska issued a corrected ballot. With only three weeks to go before the regional corporation’s annual meeting on June 28, the Sealaska4 candidates are pressing Sealaska for a response.The Alaska Supreme Court’s decision in Rude v. CIRI now requires Alaska Native corporations to disclose on proxy ballots how discretionary votes will be allocated. Wanamaker says that Sealaska’s proxy ballot does not include the necessary explanation.“It appears that Sealaska’s ballot advisors failed to adequately consider the new voting rules,” said Wanamaker. “The result may be that Sealaska will have to assign discretionary votes equally to its board slate candidates.”According to Wanamaker, discretionary voting is a controversial practice long used by Sealaska to distribute votes in unequal amounts to elect as many of the board slate candidates as possible. “This practice often results in the election of incumbent directors who may have weak shareholder support,”Wanamaker said.A shareholder petition forced the question of discretionary voting practice onto the 2014 Sealaska ballot. If shareholders support the initiative, discretionary voting will not be allowed in subsequent elections. Wanamaker said that considering the new court decision, and Sealaska’s apparent failure to incorporate and disclose the required discretionary voting instructions on the ballot, the corporate bylaws are open for challenge. Sealaska’s press release:“The press release by the outside group misinterprets the CIRI case and is designed to confuse shareholders. Sealaska’s proxy statement, proxy card, and bylaws all state clearly that discretionary votes will be allocated to elect the board slate candidates. It is the duty of the Independent Inspectors of Election and Voting to determine the effect of each proxy. The Inspectors of Election has independent legal counsel, and verbally advised Sealaska that the proxies are valid as written. We expect written confirmation of this conclusion. Any Sealaska shareholder voting on Sealaska’s blue proxy can be assured their votes will be counted.The press release issued by the outside group further confuses shareholders by wrongly representing the shareholder resolution. It is a resolution to reduce the use of discretionary voting on the Sealaska proxy unless an independent slate is present and also using discretionary voting. To claim that support of the initiative would disallow discretionary voting in all subsequent elections is simply not true.”last_img read more
