The Mid-Brunhes Event and West Antarctic Ice Sheet stability

first_imgThe complex cyclical nature of Pleistocene climate, driven by the evolving orbital configuration of the Earth, is well known but not well understood. A major climatic transition took place at the Mid-Brunhes Event (MBE), ca. 430 ka ago after which the amplitude of the ca. 100 ka climate oscillations increased, with substantially warmer interglacials, including periods warmer than present. Recent modelling has indicated that while the timing of these warmer-than-present transient (WPT) events is consistent with southern warming clue to a deglaciation-forced slowdown of the Atlantic Meridional Overturning Circulation, the magnitude of warming requires a local amplification, for which a candidate is the feedback of significant West Antarctic Ice Sheet (WAIS) retreat. We here extend this argument, based on the absence of WPTs in the early ice core record (450-800 ka ago), to hypothesize that the MBE could be a manifestation of decreased WAIS stability, triggered by ongoing subglacial erosion.last_img read more

Gunvor and Commonwealth LNG have entered into a Strategic LNG Marketing & Gas Supply Agreement in relation to Commonwealth’s LNG export project in Cameron Parish, Louisiana. Under the agreement, Gunvor will support Commonwealth in securing binding LNG offtake and gas supply agreements for the full capacity of the facility. In addition, Gunvor will commit to take up to 3 million tonnes per annum (MTPA) of LNG offtake from the facility.“In this highly competitive market, it is critical for companies – particularly ones pursuing an LNG greenfield project – to recognize their core competencies and strengths,” said Kalpesh Patel, Gunvor Co-Head of LNG Trading. “Commonwealth LNG’s engineering and procurement team is best in class. And, now, with the comprehensive support of Gunvor’s LNG and US Gas marketing team, Commonwealth LNG will excel not only at controlling costs and project execution, but also at commercializing their project and creating the lowest cost offering on the US Gulf Coast.“We are very pleased to announce this strategic partnership with Gunvor, the most active LNG trader in the world,” said Paul Varello, Commonwealth’s President and CEO. “We believe Gunvor’s substantial capabilities in LNG marketing and overall market presence, coupled with Commonwealth’s strengths in engineering, construction and project execution create a dynamic combination that ultimately differentiates Commonwealth from every other US LNG project currently chasing FID.”Commonwealth LNG expects to take a final investment decision in Q1 of 2021 and deliver its first shipments of LNG in Q2 of 2024.

Oriel threatens library closure

first_imgOriel have threatened to restrict the College library opening hours in response to the surge of vandalism incidents that have taken place this week.The damage includes several broken chairs and a “flagrant disregard for library regulations”. Charles B. Watson of the Oriel Classics Departmemt wrote a letter to all JCR members, condemning the vandalism and the consumption of food and drink in the library, which is strictly forbidden under library regulations. He has Urged anyone with information about the broken chairs to come forward. He warned that, “If those responsible for the broken furniture do not come forward or if library regulations continue to be ignored, the Governing Body will take drastic action at its next meeting, Wednesday of 4th Week. The current proposal is to close the library from 10pm-7am.”James Pickering, a third year, PPEist, said, “I think its fair for the College to act in this way. People have been taking trashy food into the library and stinking out the place. “It just seems absurd for people to transgress the rules in this way and as far as I’m concerned there is no need for it. Of course it is a massive hindrance. I do know people who work in the late hours of the evening and will find it very difficult if the library is closed over night. But I can’t see any other way of getting people to stick to the rules, which I think are completely reasonable”Nick Gallagher, a third year Classics and English student, said “Oriel’s library is open for 24 hours a day, this is obviously a tremendous resource. “I would certainly find it an inconvenience if the library was closed overnight and my work would suffer as a result.”last_img read more

Bakery sees mixed success with exports

first_imgBakery exports had mixed results in the first half of 2010, as total UK exports of food and non-alcoholic drinks grew by 4.3%.According to research from Leatherhead Food for the Food and Drink Federation, sweet biscuits grew by 6.6% to a total of £102.2m compared to the same period in 2009, while cakes rose by 9.8% to £87.2m. However, bread exports dropped significantly, down 9% to £40.7m, and savoury biscuits fared even worse, falling 9.7% to £14.6m.Overall, UK food and drink exports fared well during the period, growing to over £5bn, thanks to a 23% increase in sales to non-EU countries for British products. Demand from countries in the EU was flat, with sales down 0.2%. Sales to countries outside the EU now accounts for 22.7% of all exports.“I am delighted to see another strong export performance from UK food and drink manufacturers,” said Melanie Leech , director general of the Food and Drink Federation. “If these levels continue throughout 2010, we should see our sixth consecutive full year of growth and break the £10bn mark for exports for the first time.”>>Mrs Crimble’s boosts its transatlantic listings>>Strong exports for biscuitslast_img read more

Detailed metabolic profile gives “chemical snapshot” of the effects of exercise

first_imgUsing a system that analyzes blood samples with unprecedented detail, a team led by Harvard Medical School (HMS) researchers at Massachusetts General Hospital (MGH) has developed the first “chemical snapshot” of the metabolic effects of exercise. Their findings, reported today’s edition of Science Translational Medicine, may improve understanding of the physiologic effects of exercise and lead to new treatments for cardiovascular disease and diabetes.“We found new metabolic signatures that clearly distinguish more-fit from less-fit individuals during exercise,” says Gregory Lewis, an HMS instructor based at the MGH Heart Center, the paper’s lead author. “These results have implications for the development of optimal training programs and improved assessment of cardiovascular fitness, as well as for the development of nutritional supplements to enhance exercise performance.”The beneficial health effects of exercise – including reducing the risk of heart disease, stroke and type 2 diabetes – are well known, but the biological mechanisms underlying those effects are unclear. Previous investigations of exercise-induced changes in metabolites – biological molecules produced in often-minute quantities – have focused on the few molecules measured by most hospital laboratories. Using a new mass-spectrometry-based system that profiles more than 200 metabolites at a time – developed in collaboration with colleagues from the Broad Institute of Harvard and MIT, led by Clary Clish, PhD – the MGH-based team analyzed blood samples taken from healthy participants before, immediately following, and one hour after exercise stress tests that were approximately 10 minutes long.Exercise-associated changes were seen in more than 20 metabolites, reflecting processing of sugars, fats and amino acids as fuels as well as the body’s utilization of ATP, the primary source of cellular energy. Several changes involved metabolic pathways not previously associated with exercise, including increases in niacinamide, a vitamin derivative known to enhance insulin release.Another experiment that analyzed samples taken from different vascular locations indicated that most metabolite changes were generated in the exercising muscles, although some appeared to arise throughout the body. In both experiments, several metabolite changes persisted 60 minutes after exercise had ceased.In an experiment designed to assess the effects of prolonged exercise, pre- and post-race samples were taken from 25 runners who completed the 2006 Boston Marathon. Extensive changes in several metabolites – some different from those produced by brief exercise – were seen in the post-race samples. Indicators of increased metabolism of fats, glucose and other carbohydrates rose in response to both brief and prolonged exercise, but in marathoners amino acid levels also fell significantly, reflecting their use of amino acids as fuel to maintain adequate glucose levels during extended exercise.The researchers also analyzed how these metabolite changes related to participants’ level of fitness – determined by peak oxygen uptake in the short-term experiments and by finishing times for the marathon runners. In both groups they found that several changes, including those reflecting increased fat metabolism, were more pronounced in participants who were more fit.Pursuing the hypothesis that metabolites which increase in response to exercise act on pathways involved in cellular respiration and glucose utilization, the investigators applied different combinations of metabolites to cultured muscle cells. They found that a combination of five molecules increased expression of nur77, a gene recently shown to regulate glucose levels and lipid metabolism, making it a possible treatment target for the combination of cardiovascular risk factors known as metabolic syndrome. The association of nur77 levels with exercise was supported by an experiment that found gene expression increased fivefold in the muscles of mice that had exercised for 30 minutes.“Our results have implications for development of both diagnostic testing to track and improve exercise performance and for interventions to reduce the effects of diabetes or heart disease by improving a patient’s metabolic ‘fingerprint’,” explains HMS associate profressor Robert Gerszten, MD, director of Clinical and Translational Research at the MGH Heart Center, the study’s senior author. “Improving the health of people with cardiovascular disease is our number one goal, but defining which metabolites become deficient and need to be replenished during exercise could also lead to the next generation of sports drinks that can help healthy individuals achieve their best exercise performance.”The study was supported by grants from the National Institutes of Health, the Donald W. Reynolds Foundation, Fondation Leducq, and the American Heart Association.Additional authors of the Science Translational Medicine paper are Laurie Farrell, Malissa Wood, MD, Maryann Martinovic, Susan Cheng, MD, Rahul Deo, MD, PhD, Aarti Asnani, MD, Marc Semigran, MD, and Thomas Wang, MD, MGH Heart Center; Eugene Rhee, MD, and David Systrom, MD, MGH Department of Medicine; Amanda Souza, Elaine Yang, Xu Shi, MD, Steven Carr, PhD, and Clary Clish, PhD, Broad Institute; Zoltan Arany, MD, and Glenn Rowe, PhD, Beth Israel Deaconess Medical Center; Elizabeth McCabe, MS, Framingham Heart Study; Frederick Roth, PhD, Harvard Medical School; Ramachandran Vasan, MD, Boston University School of Medicine; and Marc Sabatine, MD, Brigham and Women’s Hospital.last_img read more

Community and School Gardens

first_imgA recent survey found there were more than 360 community and school gardens across the state. With that many Georgians gardening, there are bound to be questions about picking the right crops, identifying insects and improving garden soil. To that end, University of Georgia Cooperative Extension is expanding its already existing community and school garden outreach efforts. Becky Griffin, who has a long history of working with urban agriculture in metro Atlanta, was recently appointed UGA Extension community and school garden coordinator. She will lead a committee of Extension professionals enthusiastic about these types of gardens. “Over the years, we’ve developed many resources for gardeners and groups working to develop community and school gardens, but there was no coordinated effort,” said Laura Perry Johnson, associate dean for Extension with the UGA College of Agricultural and Environmental Sciences. “Becky’s new role will be to help us coordinate our efforts and speak with one voice on this subject to ultimately have greater impact and be of larger service. This will keep us from re-inventing the wheel at each new garden site and improve our public outreach as new challenges and opportunities come to light.” The new community and school garden committee kicked off efforts by putting on this summer’s school garden teacher trainings. Griffin worked with UGA horticulture professor and school garden advocate David Knauft to organize trainings for north Georgia teachers to help them maximize the use of their school gardens in the classroom. The workshops were designed for beginning gardeners and focused on building healthy soil, pest management and garden planning. The trainings also provided advice for developing lesson plans that use school gardens to teach Georgia Performance Standards. “I have a garden at my school, but I want to be able to integrate it more into my lesson plans,” said Karrie Churchwell, a sixth-grade teacher at Duluth Adventist Christian School, who was one of about 100 teachers attending the school garden trainings this summer. “This was really helpful in terms of learning what to grow, so you can maximize the use of the garden during the school year.” More teacher trainings are planned for summer 2016 as well as more advanced trainings for teachers who are already comfortable in their gardens, Griffin said. In addition to helping teachers make the most their school gardens, UGA Extension and Georgia 4-H are teaming up to use school gardens to help students learn about life sciences, agriculture and the importance of service. Georgia 4-H programs in several schools will be presenting programs centered on school vegetable gardens. Fifth-grade students will learn pest identification skills, explore food preservation methods and discover how to properly read a seed packet. These students will not only learn about the living world, but they will also become valuable assets to their school gardens. Griffin’s community and school garden committee will work closely with UGA Extension agents to help them meet the needs of school and community organizers across the state. Currently, Griffin is working with stakeholders to develop a directory of resources. “One of our next projects is to assess the resources that are already in place throughout the state to help community and school gardeners,” said Griffin. “We will promote those resources and create materials that we find are lacking.” Future projects include the encouragement and promotion of pollinator gardens or plots. The statewide pollinator protection plan, “Protecting Georgia’s Pollinators,” by a team of Georgia agricultural experts from UGA and the state Department of Agriculture, was released earlier this year. As a result, pollinator gardens are being looked at as a great asset. The committee also plans on expanding the use of technology to broadcast relevant information. The UGA Extension community gardening blog at blog.extension.uga.edu/communitygardening informs the public on garden issues as well as upcoming classes and events. The UGA school garden resource site at extension.uga.edu/k12/school-gardens/ provides teachers with information on basic gardening and lesson plans for Georgia classrooms. There are plans to expand these resources and to add similar programs.last_img read more

Mountain Mama: Reflecting on a Month of Vanlife

first_imgToward the end of our month-long road trip my six-year old son slid open the door of our van. We both exclaimed when we saw our camp spot blanketed in white.Snow!“Oh shit,” I said, worrying about how we’d manage the last mountain pass. I’d planned on eating breakfast on the road and arriving at our next destination, five hours away, by noon.At the same time my son said, “This is going to be the best day ever! We get to play in the snow.”One glimpse of the smile that filled his face made me forget my plans. We bundled up, layering every piece of dry clothing for the unanticipated colder temperatures. We walked along the beach, gaping at the way snow transformed the familiar into something else, casting our world into a magical white hue. My son threw a snowball at me and I tickled him, turning into a session of making snow angels.Other days of our road trip didn’t turn out so well. There was the time we slid off the road into a muddy bog when we were supposed to be zip lining, races against the fuel tank to the gas station, and contending with the mess that inevitably accumulated in our van minutes after cleaning. Every time I stumbled over another small Lego piece I regretted bringing along a bag full of impossibly small pieces that scattered into every nook.I didn’t intentionally set off to try out a month of vanlife with my six-year old. I was craving an adventure and given that my son lives with me the majority of the time, the assumption was he comes wherever I go. The days leading up to our trip filled me with equal parts anticipation and dread. Sometimes living with my son in the ease of our home feels difficult, how would we fare for a month without screens or school or other people confined in a small place?The day I picked up the rental van, I thought I made a big mistake. After a dozen failed attempts, the ignition finally started. Later I found out the key was a copy made off a copy so the angle had to be exactly right before the engine started. My son and I high-fived every time the engine purred and it became an inside joke to count how many tries it would take.Driving a campervan necessitated my son riding shotgun. “So this is what the front seat is like,” he said. He didn’t ask to watch his Kindle, he was so interested in helping me navigate and observing the scenery.A month together of watching sunrises and sunsets, finding the trailhead together and skipping rocks, of starting the morning with the same question – what fun thing are we going to do today? – helped me know my son. He told me his secrets and prattled on about the details of school life. During the course of every day life he didn’t want to answer my questions about how school was that day, but for some reason uninterrupted days with nothing to do but talk he shared more. I asked for his input more – where he wanted to camp that night, when he wanted to stop driving for the day, whether he wanted to hike or bike.  He learned to transform the van benches into a bed while I cooked dinner. A month of van life changed our relationship and I glimpsed how our mother – son relationship might one day evolve into friendship. The day we returned the van gratitude filled that I had the opportunity to know who my son was as at six-years old, and he was pretty cool.last_img read more

With election nearing a resolution, investors see some market-friendly themes emerging

first_imgTraders agreed that the Federal Reserve would remain accomodative and that some kind of fiscal stimulus was coming from Congress, but there’s no agreement on the timing or size of the deal.“I think it’s certain that the Fed is going to continue to be extraordinarily easy for a long  time to come…and I also think that it’s certain that we’re going to get fiscal stimulus.” Strategas Research Partners Chairman Jason Trennert told CNBC. Liz Young, BNY Mellon Investment Director of Market Strategy, said stimulus would now dominate the markets. “Both parties want stimulus,” she told CNBC. “That’s going to drive a rally  that’s going to drive positivity and the sequence of events matter so if you get a fiscal  package and a vaccine around at the same two or three-month period that’s huge upside in the stock market.”The good news: Senate Majority Leader Mitch McConnell said a stimulus bill would be the Senate’s top priority before year end, and indicated aid to states — a major stumbling point in prior negotiations — might be included.Everyone will be tough on ChinaNo matter who wins, the stance toward China has hardened. “I think we pick a fight with China no matter what,” Peter Tchir from Academy Securities told me.Not everyone is convinced. “The world expects Biden to be easier on China, I hope that is not true,” Kyle Bass said on CNBC, noting that the dollar weakened against the Chinese currency when Biden appeared to be in the lead.Protecting vital U.S. industries will be a theme under either administration: “I think there is going to be huge pressure to bring medical manufacturing back home,” Peter Tchir told me. “Why are we producing essential medicines in China?”Trade and the dollarIndeed, many traders agreed that “economic nationalism” — bringing supply chains back to the United States — would be a theme under the Biden administration as well. “Biden’s Made in America is the import substitution strategy that is very close to Trump,” Marc Chandler from Bannockburn Global Forex told me. The differences between them, he says, “Is more about style than substance.”Trade agreements are a different matter. Noting that that the U.S. is formally leaving the Paris Accord, Chandler said  Biden will seek to rejoin that agreement.As for the dollar, both the import substitution strategy and the monetary and fiscal policy mix lends itself to a weaker dollar.“We will have a twin deficit: we will have a budget deficit, and a large trade deficit,” Chandler told me. “U.S. interest rates should be expected to rise to attract investors, but rates can’t rise much, so the alternative is to have the dollar lower. As the U.S. borrows more money, the dollar will fall.” He too pointed to the strength of the Chinese yuan against the dollar.Bigger government, no matter who is in the White House?No matter who wins, many feel the 2020s “will be characterized by bigger government,” Bank of America said in a recent note to clients, citing among other things, the wider acceptance of Modern Monetary Theory (MMT) that proposes governments should not worry about deficits and should print money unless it becomes inflationary.David Kelly from JP Morgan agrees: “In today’s environment of near-zero or even negative interest rates and massive central-bank purchases of government securities, we are witnessing a move in the direction of MMT.”Others cite the growth of Environmental, Social & Governance (ESG) investing, which implies investors pushing for more social changes and increased government regulations.For the moment, a Goldilocks marketFor the moment, these broad policy questions are being put aside as traders celebrate the potential for a perfect scenario: a new President with a check on his ability to raise taxes and impose more regulation.“We are going to have a much better economy next year than a lot of people realize, regardless of who is in power,” Tchir told me. “We are really going to get the stimulus that goes beyond the band-aid, with big infrastructure, and attempts to repatriate jobs from abroad.”Subscribe to CNBC PRO for exclusive insights and analysis, and live business day programming from around the world. What’s next for markets? With the election over, some old themes will be re-emerging, regardless of who will be president. The rally is due to better earnings visibility- Advertisement – – Advertisement – “The good news is the uncertainty surrounding a very contentious election should soon be behind us, and investors can focus on the macro influences that ultimately drive direction: inflation, interest rates, money availability, and the prospects for domestic and global growth,” Tony Dwyer from Cannacord Genuity wrote in a note to clients.In discussions with traders, several “old themes” came up over and over: the extent of fiscal and monetary stimulus, China policy, and trade and the dollar. One important trend either president will be facing:  the prospects for much bigger government.Fiscal and monetary stimulus: how much?- Advertisement – On one issue, all traders agree: the market rally is largely due to the unlikelihood of higher corporate and individual taxes next year.“The Senate numbers from the 2020 election indicate that higher corporate taxes are unlikely, giving us and others more conviction in 2021 EPS estimates,” Tobias Levkovich from Citigroup said in a note to clients. Like many, Levkovich estimated that higher taxes could shave at least 5% off earnings in 2021, but “that possibility has dissipated,” Levkovich said.Back to fundamentals- Advertisement –last_img read more
