As waters warm, Arctic fish populations change

(Photo courtesy of NOAA)A new report shows more fish are moving to Arctic waters. The U.S. Geological Survey and the Bureau of Ocean Energy Management teamed up to create the inventory, which describes more than 100 species of fish found in the Chukchi and Beaufort Seas — including 20 species new to the region.The Alaska Arctic Marine Fish Ecology Catalog for the Beaufort and Chukchi Seas has been a long time coming. Biologist Milton Love has been working on the project since 2009. He says both Arctic seas appear to be changing.“We’re starting to see either new introductions of temperate fishes from the south or at least larger numbers of them, particularly in the Beaufort Sea,” said Love.At this point, Love isn’t sure what these changes mean for fish traditionally found in the Arctic. Since the area has historically been difficult to sample, it’s hard to establish if fish are coming from the south, growing in population, or both.One species that could be affected is Arctic cod, a major player in the marine food web. Love says the species does better in near-freezing water.“If ice becomes less predominant over time and waters warm, then perhaps Arctic cod will not do as well,” he said. “There are a number of predatory birds and mammals that certainly feed in great quantity on Arctic cod.”If those species aren’t able to eat anything else, they could be impacted, too.Because of the importance of Arctic cod, the team analyzed the effects of a warming climate on the species as well as its major competitor – saffron cod. As temperatures rise, both species will likely shift north. That would expand the range for saffron cod, but restrict the range for Arctic cod.Love sees a wide range of uses for the new report, from evaluating environmental impacts on the region to monitoring changes in fish distribution and managing fisheries. It also includes traditional Iñupiaq names to improve communication between researchers and local communities.Share this story:last_img read more

Of course you haven’t. It was never made. But the week’s best writing about movies includes a story about the filmBy Daniel Schindel – May 23, 2014613ShareEmailFacebookTwitterPinterestReddItHow YouTube and Internet Journalism Destroyed Tom Cruise, Our Last Real Movie Star by Amy Nicholson at LA WeeklyRemember how Tom Cruise broke the internet by jumping up and down on Oprah’s couch? We all do. There’s only one problem. It didn’t happen. But YouTube and Perez Hilton made you think it did. Nicholson dives into how Cruise, who once controlled his public image with military rigor, was blindsided by new media. Now that Cruise, who once showed real creative initiative, has been branded “crazy,” he sticks to safe, mainstream projects. It’s a sad tale.“Don’t be an a–hole,” an interview with Richard Linklater by Matt Zoller Seitz at RogerEbert.comThe strangest movie-related news to come out recently was that convicted murderer Bernie Tiede, the subject of director Richard Linklater’s 2011 movie Bernie, had been released from jail on one condition: that he live with Linklater. This interview with Linklater starts by talking about the filmmaker’s masterful new movie, Boyhood, but turns to what it’s like to have a convicted killer living above your garage.Samurai Robots, Nude Robin, and Monster Love: The Batman-Godzilla Movie That Could Have Been by Matt Patches at GrantlandIn 2015, Batman will battle Superman. This summer, Godzilla stomps through theaters. But back in the 1960s, Adam West’s Batman nearly fought Godzilla. Read this amazing summary of the aborted film’s treatment and you’ll likely be convinced that Batman Meets Godzilla is one of the greatest movies never made. Michael Bay: Futurist by John D’Amico at Smug FilmFew critics have nice things to say about the work of Michael Bay, but they usually praise the special effects in his movies. Here, D’Amico examines how, intentionally or not, the man has created a visual style that’s akin to cubist artwork. The comparisons of frames from the Transformers movies and futurist paintings are striking. Does this make Bay a skilled visualist? No, but this story is worth reading. What’s Really the Matter with Cannes and Documentaries? by Daniel Walber at NonficsTalk of Cannes, the world’s premier film festival, has been at the top of most film-related conversations this past week.

Thomas Piketty rejects France’s Legion of Honour award

first_imgFrance’s rock star economist Thomas Piketty has turned down France’s highest state honour because, in his view, it is not the role of the government to dispense these kinds of awards.The economist made waves in 2014 and topped the Amazon bestseller list with his book Capital in the 21st Century, which postulated that inequality will soar under capitalism’s current trajectory because the rate of return on capital (r) tends to be higher than the growth rate of the economy (g). According to Agence France-Presse, Piketty said:I just found out that I have been proposed for the Legion of Honour. I refuse this nomination because I do not think it is the government’s role to decide who is honourable.He added:They would do better to concentrate on reviving (economic) growth in France and Europe.Piketty’s native France has been beset by economic woes with high unemployment, poor growth and failure to meet its deficit targets. France was recently overtaken by Britain to become the world’s fifth largest economy and recently abandoned its much ridiculed 75 per cent tax rate on the rich.Piketty was at one time close to President Hollande’s Socialist government but has since distanced himself from the administration. In Britain, the Queen’s New Year Honours list was recently revealed, which included Esther Rantzen and Sheridan Smith.

South Korean Conferences on North Korea’s Military-First Policy?

first_img RELATED ARTICLESMORE FROM AUTHOR Tracking the “unidentified yellow substance” being dried out near the Yongbyon Nuclear Center AvatarDaily NKQuestions or comments about this article? Contact us at [email protected] Is Nuclear Peace with North Korea Possible? [imText1]I’ve recently heard that South Korean experts held conferences on the Military-First Policy of Chosun (North Korea). Although I am glad that South Korean interest in North Korea is increasing, I wonder how well they understand a Military-First Policy whose underpinnings are not as complex as scholars may believe.Kim Jong Il’s visit to the Dabaksol guard post in 1995It was in 1998 when the phrase “military-first” was first used in North Korea at the Dabaksol guard post located in the suburban district of Mankyungdae in Pyongyang.The media stated that “the Great General, Kim Jong Il visited Dabaksol guard post on January 1st, 1995, while North Korean citizens gathered in front of televisions and a public stage, in expectation of seeing the General in a New Year’s performance.” At the time, the annual national ceremony and performance were held on January 1st with the announcement of a New Year’s Address by Kim Jong Il. However, Kim Jong Il did not appear and instead made a sudden visit to a small guard post in order to illustrate his priority on the military. Therefore, the Dabaksol guard post visit marks the military-first policy. “The great general,” Kim Jong Il declared that the only hope for North Korean socialism was the strong sustenance of the People’s Workers’ Army in order to combat the evil imperialists’ economic blockade and policy of isolation.” After Kim Il Sung died, the Party’s publication arm produced “The Six Years to Defend the Red Flag” and claimed the phrase. In “Immortal Leadership,” a famous revolutionary history book, also mentions the beginning of military-first policy: “Kim Jong Il visited Dabaksol guard post with his rifle in 1995.”The military-first policy = a single party dictatorship + a military dictatorshipIt is said that Kim Jong Il raised his rifle resolutely as he outlined the alternatives: either to live independently or as slaves under the imperialists: “Our people know very well that we can survive without candies but we can’t live without bullets. Initially I did not use the phrase military-first because it reminds me of military-dictatorship. However these days, our military-first policy has spread all over the world. So I name the policy “the Military-First Policy” as the principal policy of the Party, from now on.”After that, priority on the military and the military-first atmosphere spread out throughout the country. In 2000, authorities claimed that the superiority of the military-first policy had been proven worldwide. In 2002, they combined the military-first policy as an ideology of independence and political theory. Practically, there is no ideological background or political theory involved. The General is in complete charge of a single party, military dictatorship whose propaganda officers use revolutionary tradition and ideological-theoretical excuses to hide the failings of the military-first policy. North Korean teachers of revolutionary history continually accented the genesis of “the military-first policy.” Prior to 2002, one could ace the revolutionary history exam by remembering that visiting the Dabaksol guard post in January 1st, 1995” was the starting point of the military-first policy. After late 2002, the correct answer was changed to indicate the starting point of the military-first policy which was April 25th 1932, when the Great Leader Kim Il Sung commanded a guerrilla unit against Japan.” It was not the end of the revisions. In 2003, universities in Pyongyang held a competition on the study of Kim Jong Il’s revolutionary history. Yet another theory appeared which claimed that “1962 was the starting time of the military-first policy.”“February 5th, 1962” was the day Kim Jong Il first visited Mt. Daeduk guard post and gave instruction.” After that, teachers and students became confused over when the policy began and argued with each other. For a while, all evidence of the policy’s inception disappeared from documents, articles, and educational books– including the Dabaksol guard post story. Visiting at the Ryu Kyung Soo tank division in 1960Suddenly on August 25, 2006, Chosun Central TV said that the start of the military-first policy was August 25th, 1960 when Kim Jong Il visited in the Ryu Kyung Soo tank division, and the government designated the day, August 25th as a national holiday. Celebratory banners commemorating the 46th anniversary of the military-first policy appeared throughout Pyongyang. A professor at my university said cynically “If the upper (authority) picks this day, then this day is correct, or if the upper picks that day, then that day is correct. I am really ashamed that I have to change the story again.”The U.S. has the strongest military in the world and has no military-first policy. Japan’s economy is widely respected and they have no military-first policy. South Korea has become a first-world country by its resistance to military participation in government. What benefits has the military-first policy produced in North Korea over the last 50 years? Nothing. It exists solely to perpetuate a military dictatorship that completely suppresses its people. The muzzle of the Kim Jong Il’s military policy is not exclusively aimed at American imperialists and the “puppet” regime of South Korea, but at Kim’s own starving people. True understanding of Chosun military-first policy cannot be obtained through consumption of Kim’s propaganda, but by observation of the lives of its people who can’t help but to be amused by the South Korean conference.

Health Ministry Confident Malaria Outbreak Under Control

first_imgFacebookTwitterWhatsAppEmail The Ministry of Health continues to remain confident that the malaria outbreak is under control. Speaking yesterday (January 22), at the weekly post-Cabinet press briefing at Jamaica House, Minister of Information and Development, Donald Buchanan told journalists that Cabinet received an update from the Minister of Health, Horace Dalley.“The Minister has basically indicated continuing progress in terms of the elimination and containment of the outbreak of malaria, but indicated that in the Greenwich Town area of Kingston there had been an unusual level of cases in the last couple of weeks and this has somewhat exacerbated what otherwise, is a continued programme of containment,” he said.Mr. Buchanan said that the Ministry had reported that, “it is now fully on top of the situation”. Since the outbreak of malaria in a few areas in Kingston, the Ministry has worked feverishly to implement a number of strategies to control the disease.These include house to house surveys in the affected areas; prompt treatment of suspected cases; vector control; public education and inter-sectoral collaboration.

At the centre of the exhibition, which ran from September to December, was a series of lithographs entitled ‘Sketches of Character’, made by Jewish Jamaican born artist/curator, Isaac Mendes Belisario. This provided a visual presentation of Jonkonnu (John Canoe), the celebrated Afro-Jamaican masquerade performed by slaves during the Christmas and New Year holidays. Organized to commemorate the bicentenary of the abolition of the Transatlantic Slave Trade in 1807, the exhibition also featured works from private and public collections in Jamaica, including the National Gallery of Jamaica, the National Library of Jamaica, the Institute of Jamaica as well as organisations in the USA and Great Britain.The exhibition was supported by The Reed Foundation, USA.center_img RelatedArt Exhibition on Slavery and Emancipation Ends at Yale Advertisementslast_img read more

Biochemists untangle mysteries of cellular form, function

first_imgDistinguished Professors Karolin Luger (left) and Natalie Ahn at the Jennie Smoly Caruthers Biotechnology Building. Photo: Glenn J. Asakawa / University of Colorado BoulderThe complex inner workings of cells, from their architecture to their signaling, underlie much of multicellular organic life. How are they built? How do their proteins interact? And most crucially, how can understanding these functions improve our knowledge of biological outcomes such as disease?CU Boulder Distinguished Professors Karolin Luger and Natalie Ahn have studied questions such as these for decades. Last year, both were elected to the National Academy of Sciences, one of the most prestigious honors a scientist can receive. The duo will be formally inducted on Saturday, April 27, at the organization’s annual meeting.“It’s a high honor because it comes from peers,” said Luger, the endowed chair of CU Boulder’s Department of Biochemistry and a Howard Hughes Medical Institute Investigator. “It’s primarily a wonderful acknowledgement of the collective work of all the former and present students, post-docs and technicians who have contributed to this research.”Like an archeologist piecing together the origins of ancient structures, Luger and her students examine the fundamental building blocks of genomic processes and untangle their cellular machinery.Luger began her career with an interest in x-ray crystallography, a technique used to discern 3D molecular structures. Eventually, her focus shifted to chromatin, the material that holds DNA, RNA and proteins together in a compact package within eukaryotic cells. As recently as the late 1980s, before the advent of the Human Genome Project, chromatin was thought to be unimportant, similar to packaging material that only serves to hold more valuable items inside.“It was a binary mentality back then, but it turned out to be much messier, with lots of variation between individual cells,” Luger said. “The packaging, so to speak, has very important implications for how cell types differentiate.”Imagine a space filled with labeled cardboard boxes full of books, she says. By reading the labels on the boxes, humans can discern which boxes they’ll need soon and which ones they can safely stash away. Chromatin operates similarly: A fertilized egg cell needs everything—all the genomic information it can get—whereas a more mature cell, such as a liver cell, can read the packaging and know what it can safely ignore.Early advances in electron microscopy revealed chromatin’s elegant structure, which appears as “beads on a string,” dotted with nucleosomes. Luger went on to determine the structure of nucleosomes at near-atomic resolution, revealing the structure of DNA in all multicellular organismsMore recently, Luger has been examining how and why many multicellular organisms—humans, yeast, trees—all fold their DNA using the same molecular mechanisms. In 2017, her lab and collaborators identified the microbes Archaea (which predate multicellular organisms by 3 billion years) as the likely ‘inventors’ of genome folding and nucleosome structure that we still observe today.“I’m always interested in how these structures came about,” she said of the evolutionary discovery. “It’s a lot of work to bend DNA, and Archaea had developed a nifty system to do this, which was then appropriated and further refined by the first eukaryotic organisms.”Luger credits her students and post-doctoral researchers for their painstaking work on these research topics, adding that she deliberately recruits from different backgrounds such as physics, cell biology and chemistry in order to cultivate interdisciplinary problem-solving.“Students come in with new ideas for everything and help me view a scientific problem from all angles,” she said. “You have to let yourself be challenged.” Ahn arrived at CU Boulder over 25 years ago, bringing expertise in the field known as signal transduction, which involves enzymatic processes that allow cells to respond to external signals.  Ahn was the first to describe the enzyme known as mitogen-activated protein kinase kinase (MAP2K), now known to be a crucial activation point in some types of cancer, particularly melanoma. Upon arriving at CU Boulder, she and her new lab proved that aberrant activation of MAP2K causes cancer, making this enzyme a viable target for therapeutic intervention.  The ubiquity of MAP2K in all cells—healthy and diseased alike—led to initial skepticism that it could be a useful drug target, Ahn said, but several cancer-inhibiting treatments focusing on MAP2K have subsequently been approved by the FDA for clinical use.“Many thought these would never become drug targets because there might be too many side effects,” Ahn said. “But it turned out that, remarkably, the drugs are actually very well tolerated, even more so than chemotherapy.”Ahn was also a pioneer in the field of proteomics, which determines the chemistry of proteins by “weighing” molecules using a technology called mass spectrometry.  She was an early investigator to adopt proteomics technologies, and use them to study signal transduction.  Proteomics is now widely applied in all aspects of biosciences.For Ahn, her election to the NAS came as a pleasant surprise, the culmination of a long career in basic research that has yielded promising avenues for clinical discoveries.“I can’t quite believe it, but I’m grateful and lucky enough to have really great scientists as colleagues,” Ahn said. “The university gave me the space to be creative in my research.”The dual NAS recognition also speaks to the cumulative strength of CU Boulder’s biochemistry discipline, which recently became a stand-alone academic department in the College of Arts and Sciences.“Abraham Lincoln founded the National Academy of Sciences to give trustworthy scientific advice to the President,” said Distinguished Professor Thomas Cech, CU Boulder’s first Nobel laureate and the director of the BioFrontiers Institute. “Being elected to the NAS is a rare honor, and in a typical year zero or one scientist might be elected from the entire state of Colorado. So for a single department to have two of its faculty elected in the same year is therefore rare and it’s worthy of celebration!”“This is an amazing department with a strong teaching mission,” Luger said. “We always have undergraduates participating in the labs who bring a lot of excitement and energy. There is tremendous opportunity here.” Categories:Getting InvolvedCampus Community Share Share via TwitterShare via FacebookShare via LinkedInShare via E-mail By Trent Knoss • Published: April 25, 2019 last_img read more

JEA Supports Scrap Metal Ban

first_imgRelatedJEA Supports Scrap Metal Ban FacebookTwitterWhatsAppEmail KINGSTON — The Jamaica Exporters’ Association (JEA) has come out in full support of the government’s decision to put a temporary ban on the controversial scrap metal trade. President of the JEA, Vitus Evans, addressing a press briefing at the organisation’s Winchester Road offices in Kingston on Wednesday July 20, said that with the problem that the industry is facing “we certainly support the decision taken by the Minister to bring a halt to the trade until there’s proper regulation and to ensure that we don’t actually affect our own productive sector.” Industry, Investment and Commerce Minister, Hon. Dr. Christopher Tufton on Tuesday July 19 announced a temporary shutdown of the industry, which he described “as parasitic in nature as rogue dealers continue to infiltrate the trade feeding off legitimate businesses to survive”. A number of businesses in the country’s productive sector, including agriculture and telecommunications, have suffered at the hands of unscrupulous persons, who steal genuinely good material to trade as scrap metal.  Mr. Evans said this abuse of the county’s productive sector cannot continue and that the ban should remain in place until the industry can be properly regulated. “So, we hope that there will be proper regulation and that we will get back to a position where we can have a genuine trade in the export of scrap metal and that the industry itself can actually continue to grow, but by exporting genuine scrap metal, not to actually scrap things to export,” he remarked.  The JEA President said the scrap metal industry has been one of Jamaica’s major growth areas, with the industry raking in billions of dollars in exports over the last several years. “Even a few years ago, exports of scrap metal were in an excess of $100 billion. However, that was at a time when what was being exported was genuine scrap metal,” he noted.
