A cumulative total of over 5 years of data from an MF radar situated at Rothera (67°S, 68°W) on the Antarctic Peninsula have been used to derive climatologies of periodic motions in the wind field in the mesosphere and lower thermosphere with periods less than or equal to 1 day. Strong tidal motions are observed at 24, 12 and 8 h and monthly mean climatologies are presented between 74 and 94 km altitude for comparison with the HWM-93 horizontal wind model. The 24 h tide shows a strong seasonal dependence in both the zonal and meridional components with a summertime maximum and wintertime minimum over all altitudes. The monthly mean maximum amplitude is 12(±2) ms−1 at 94 km in January and the minimum is <1 ms−1 around 86 km in early winter. The 12 h wave shows large short-term amplitude variability with a peak in amplitude around late autumn. It reaches a minimum at high altitudes in winter and below 80 km during summer, characteristic of a mixture of migrating and non-migrating modes. The phase of the 12 h wave is relatively constant throughout winter with a minimum mean vertical wavelength of 75 km around equinox. The 8 h wave is predominantly a summertime high altitude phenomenon. It is seen most strongly in the winds above 85 km and reaches monthly mean amplitudes of 6(±2) ms−1 in the zonal winds at 94 km altitude. Finally, a seasonal climatology of gravity wave variances is generated by calculating the daily mean variance in the raw winds after subtracting the fitted tidal components. This index shows a strong seasonal and height dependence in both components with a wintertime peak of 2000 m2s−2 in the zonal component at the highest altitudes. This peak occurs when the stratospheric zonal jets are strongest and therefore the filtering of upward-propagating waves in the stratosphere should be greatest; implying that either a significant part of this wintertime wave activity is generated from a region above the peak stratospheric wind or that there is a strong annual variability in the source or propagation of the gravity wave activity at Rothera.

Inclusions supplier Pecan Deluxe Candy has raised more than £3,500 for a cancer charity.Staff and management at the Leeds-based business are supporting Jacqui’s Million, a charity set up by a terminal cancer sufferer to raise £1m for Leeds Cancer Centre.The charity was founded by Jacqui Drake, who has personal ties to the company. She was first diagnosed with melanoma in 1991 and despite setbacks has beaten the odds for survival.Activity by Pecan Deluxe Candy has included support for a book launch, an 80s night, donation of auction prizes and staff initiatives including a Christmas Jumper Day and Festive Buffet.The company is sponsoring the Positive Vibes Cabaret Concert in Leeds on 30 June, and many factory and office staff at the business are running in the Yorkshire Marathon Relay on 14 October. Workers have formed two teams to take part in aid of the charity.“Having known Jacqui for some time we were very proud to announce Jacqui’s Million as our chosen corporate charity six months ago,” said Pecan Deluxe Candy MD Graham Kingston. “We’re all delighted to see how Jacqui’s boundless positivity and contributions from many supporters have already helped to bring in nearly £90,000 towards her target.”“I also have nothing but admiration for our teams of colleagues who will be tackling the Yorkshire Marathon – especially as more than one of them has never run an organised race before in their lives.”Established in the UK in 1999, Pecan Deluxe Candy (Europe) Ltd is a fully owned UK subsidiary of US-based Pecan Deluxe Candy Company, a family owned business founded in 1950.
Can the Earth be swallowed by a black hole? And can black holes — with their immense destructive power — themselves be destroyed?Millions apparently want to know, and a Harvard postdoctoral fellow and black-hole expert is providing the answers in educational videos that have been translated into more than two dozen languages and viewed more than 4 million times.The fellow is Fabio Pacucci, a theoretical astrophysicist studying the universe’s very earliest black holes. Pacucci, whose appointment is held jointly with Harvard’s Black Hole Initiative and the Center for Astrophysics | Harvard & Smithsonian, is developing theories to explain observations of distant, ultra-bright quasars — powered by the supermassive black holes that occupy the center of galaxies — that arose a few hundred million years after the Big Bang, some 13 billion years ago.“It seems they formed too quickly, too rapidly, to be explained by our current idea of the universe,” Pacucci said.In addition to figuring out astronomical mysteries, however, Pacucci has a strong interest in science education.“I believe it’s a very important part of the job of a scientist,” Pacucci said. “It’s part of being curious. If you want future scientists … you need people able to explain things that may be difficult.”,Pacucci began doing public outreach while studying for his Ph.D. at the Scuola Normale Superiore di Pisa three years ago and continued while conducting research at Yale University before coming to Harvard. He said having to break down difficult concepts to their basic elements in order to explain them helps his own understanding as well.“By explaining, I understand better,” Pacucci said. “Sometimes simple ideas are not so simple, and they spark new solutions for old problems.”Over the last two years, Pacucci has worked with TEDEd, the educational arm of the nonprofit idea platform TED, to develop and disseminate videos about black-hole science. Pacucci’s work with TEDEd began when a friend sent him a TEDEd video. He’d never heard of the group, and explored further, finding out that they work with educators to produce scripts on particular topics, then send the result to animators and voice-over artists who pull the video together. Pacucci sent them an email suggesting he produce something about black holes, leading with questions designed to engage the audience so they can learn.“I gave a different perspective. Instead of talking about black holes in general, asking the question ‘Could Earth be swallowed by a black hole?’ is a way to make people curious about where they [the black holes] are, how big they are,” Pacucci said. “The risks for our planet are negligible, but they learn a lot.”,That first video, “Could the Earth be Swallowed by a Black Hole?,” was released in September 2018, took six months to produce, and runs just under five minutes. It’s been translated into 25 languages and drawn 1.4 million views. The most popular of the three produced so far — and three more are in the works — is “Can a Black Hole Be Destroyed?,” which has received 1.6 million views, collected 26,000 likes, and generated more than 1,000 comments. The third and most recent, “Hawking’s Black Hole Paradox Explained,” came out in October and deals with the late black-hole expert Stephen Hawking’s theory that black holes, which swallow everything in their path, slowly evaporate over time. This means that the quantum information (the spin, position, velocity that defines each particle in the universe) of anything that fell into them may be lost forever, something that was thought to be impossible.“I think black holes have always fascinated the imagination,” said Alex Rosenthal, editorial director for TEDEd Animation. “Because of that fascination, they’re a good entry point for people to get interested in astrophysics.”Rosenthal works with educators like Pacucci to develop a script, and then hands the project to an array of animators around the globe. Those artists, he said, are given pretty wide leeway to bring the script to life, which gives the TEDEd videos a varied feel — and educators like Pacucci the benefit of their expertise.“Animators know nothing about astronomy, and I know nothing about animation,” Pacucci said.,TEDEd publishes about 150 videos a year, on a wide array of subjects, from math to science to history to language, Rosenthal said. For each video, TEDEd offers suggested course material to help teachers use it in the classroom.“We’re trying to celebrate knowledge and learning and plant the seeds of curiosity,” Rosenthal said.The videos are viewed widely. Pacucci said he’d recently heard from a student in Nepal whose teacher used a video in class. The lesson inspired the 14-year-old — who said he wants to be an astronomer — to email Pacucci, and they subsequently talked via Skype.“I think it’s a nice way to see your work being used in a positive way around the world,” Pacucci said.

A WEEKEND OF RECORD BREAKERS FOR OKEMOLUDLOW, Vt. For the second year running, the Sunday of Presidents’ Day Weekend was a record-breaker for Okemo Mountain Resort. Skier and snowboarder visits were up three percent for the day, compared to last years historic milestone, and up more than five percent compared to the previous best day in February 2005.Skier visits for the two-day period including Sat., Feb. 16 and Sun., Feb. 17 placed the weekend as the second-best two-day period over the past five years and the resort posted record revenues for the weekend. As of Feb. 17, skier visits for the season were 38 percent ahead of last year.A number of departments across the resort reported increases and set new records. Resort lodging saw a 22 percent increase in Presidents Day Weekend room nights compared to last year. On Sunday, Okemo’s Cutting Edge Learning Center hit a new high in the number of private lessons taught in a single day, and equipment rentals were up 8 percent in quantity and 13 percent in revenue over last year. Okemo Valley Nordic Center reported one of their strongest days in recent history. Record numbers of skiers and riders visited resort restaurants as well. Feb. 17 witnessed a record-breaking three-percent increase in the number of lunches served at Coleman Brook Tavern. The Roundhouse and Epic beat their previous bests by nine percent. Siena, Okemo’s Italian bistro saw a 27 percent increase over its previous best day.Okemo started the 2007-2008 ski and snowboard season with great optimism. Season pass sales were up 30 percent this year and college season-pass sales were up nearly 300 percent.Resort officials attribute the record-breaking day and year-to-date increases to favorable weather patterns and Okemos positive reputation for snowmaking, grooming and customer service.
Four St Johnsbury non-profits’Fairbanks Museum & Planetarium, St. Johnsbury Athenaeum, St. Johnsbury Academy and Catamount Arts’will jointly promote the combined arts-and-culture resources that exist within their organizations and develop new opportunities for collaboration to enhance St. Johnsbury’s cultural climate and creative economy. The group is recognizing their proximate area in St Johnsbury as the Arts & Culture Campus.‘Along Main Street from the Fairbanks Museum to the corner of Eastern Avenue at the Athenaeum, down to Catamount Arts and back over to St. Johnsbury Academy, we see a geographic link amid our shared traditions of arts programming and community outreach,’ said Jody Fried, executive director of Catamount Arts. ‘We view this area, which we’re calling the Arts & Culture Campus, as a jumping off point for arts programming in our town, inclusive of all of greater St. Johnsbury. People can come to town and easily circulate through this area to enjoy a concentration of fun happenings.’The shared histories (largely descending from the vision and beneficence of the Fairbanks family) and strengths in the arts of the four local organizations will place a sharp focus on the rich cultural programs that St. Johnsbury offers to the public.The alliance has created a logo and theme through which to advance the public’s thinking about what the town as to offer: ‘Get Inspired’St. Johnsbury’s Arts & Culture Campus.’ The logo will be used with advertising and marketing materials to position St. Johnsbury as a dynamic center for the arts, statewide and regionally.‘Our efforts will be on coordinating events to give area residents and visitors a range of arts, culture and educational activities, so once they’re in town they have a range of fun opportunities throughout a day or a weekend,’ said Anna Rubin, director of external relations for the Fairbanks Museum & Planetarium. ‘With the local non-profits working in collaboration, we see this an exponential promotion of the arts in St. Johnsbury.’ The organizations in the coalition share:Rich cultural resources for visual and performing artsFull calendars of learning programs for all agesAuthentic connections to the local heritage of the areaSupport for vibrant, dynamic and evolving new voices and expressionsAccess to artistic inspiration from around the worldEasy access on Main Street/Eastern Avenue campus. The group will be co-planning and promoting arts events beginning in 2012, kicking off with First Night St. Johnsbury 2012. They intend to coordinate their efforts with other area arts organizations, businesses, and chambers of commerce. ‘The St. Johnsbury Chamber of Commerce looks forward to fully supporting the efforts of this wonderful coalition of creative and cultural institutions here in St J We’re excited by this new opportunity to help bring more attention to the creative economy in and around town,’ said Jeff Moore, president, St. Johnsbury Chamber of Commerce.
