Experimental studies on the cold tolerance of Alaskozetes antarcticus

first_imgThe cold tolerance mechanism of the Antarctic terrestrial mite Alaskozetes antarcticus (Michael) was investigated in cultured animals. Freezing is fatal in this species and winter survival occurs by means of supercooling, which is enhanced by the presence of glycerol in the body. There is an inverse, linear relationship between the concentration of glycerol and the supercooling point, which may be as low as −30°C. Feeding detracts from supercooling ability by providing ice nucleators in the gut which initiate freezing at relatively high sub-zero temperatures. Experiments on the effects of various environmental factors showed that low temperature acclimation gave rise to increased glycerol concentrations and suppressed feeding, while desiccation also stimulated glycerol production. Photoperiod had no effect on cold tolerance in this species. The juvenile instars of A. antarcticus were found to possess a greater degree of low temperature tolerance than adults.last_img read more

Future challenges in cephalopod research

first_imgCephalopods (Mollusca: Cephalopoda) play an important role as keystone invertebrates in various marine ecosystems, as well as being a valuable fisheries resource. At the World Malacological Congress, held 21–28 July 2013 in Ponta Delgada, Azores, Portugal, a number of cephalopod experts convened to honour the contribution of the late Malcolm R. Clarke, FRS (1930–2013) to cephalopod research. Endorsed by the Cephalopod International Advisory Council (CIAC), the meeting discussed some of the major challenges that cephalopod research will face in the future. These challenges were identified as follows: (1) to find new ways to ascertain the trophic role and food web links of cephalopods using hard tissues, stable isotopes and novel concepts in theoretical ecology; (2) to explore new approaches to the study of cephalopod morphology; (3) to further develop cephalopod aquaculture research; (4) to find new ways to ascertain cephalopod adaptation and response to environmental change; (5) to strengthen cephalopod genetics research; and (6) to develop new approaches for cephalopod fisheries and conservation. The present paper presents brief reviews on these topics, followed by a discussion of the general challenges that cephalopod research is bound to face in the near future. By contributing to initiatives both within CIAC and independent of CIAC, the principle aim of the paper is to stimulate future cephalopod research.last_img read more

Needle beam stays on point

first_imgA Harvard-led team of researchers has demonstrated a new type of light beam that propagates without spreading outward, remaining very narrow and controlled along an unprecedented distance. This “needle beam,” as the team calls it, could greatly reduce signal loss for on-chip optical systems and may eventually assist the development of a more powerful class of microprocessors.Based at the Harvard School of Engineering and Applied Sciences (SEAS) and the Laboratoire Interdisciplinaire Carnot de Bourgogne, at the National Center for Scientific Research (CNRS), in France, the applied physicists both characterized and created the needle beam. Their findings were published online Aug. 31 in the journal Physical Review Letters.The needle beam arises from a special class of quasiparticles called surface plasmons, which travel in tight confinement with a metal surface. The metallic stripes that carry these surface plasmons have the potential to replace standard copper electrical interconnects in microprocessors, enabling ultrafast on-chip communications.One of the fundamental problems that has so far hindered the development of such optical interconnects is the fact that all waves naturally spread laterally during propagation, a phenomenon known as diffraction. Diffraction reduces the portion of the signal that can actually be detected.“We have made a major step toward solving this problem by discovering and experimentally confirming the existence of a previously overlooked solution of Maxwell’s equations that govern all light phenomena,” says principal investigator Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering at SEAS. “The solution is a highly localized surface plasmon wave that propagates for a long distance, approximately 80 microns in our experiments, in a straight line without any diffraction.”Researchers demonstrated a cosine-Gauss plasmon beam, dubbed a “needle beam,” that propagates without diffraction. The advance may assist the development of ultrafast, energy-efficient microprocessors. Image courtesy of Patrice GenevetThe needle beam, technically a cosine-Gauss plasmon beam, propagates in tight confinement with a nanostructured metal surface. Lead author Jiao Lin, a visiting postdoctoral fellow at SEAS from the Singapore Institute of Manufacturing and Technology, and co-author Patrice Genevet, a research associate in Capasso’s group, found an ingenious way to demonstrate the theorized phenomenon. They sculpted two sets of grooves into a gold film that was plated onto the surface of a glass sheet. These tiny grooves intersect at an angle to form a metallic grating. When illuminated by a laser, the device launches two tilted, plane surface waves that interfere constructively to create the nondiffracting beam.“Our French colleagues did a beautiful experiment, using an ultra-high-resolution microscope to image the needle-shaped beam propagating for a long distance across the gold surface,” says Genevet.Capasso’s team hopes the finding will assist the development of more energy-efficient and powerful microprocessors.last_img read more

Atmospheric river storm drenches California, snow piles high

first_imgLOS ANGELES (AP) — Evacuations have been ordered in wildfire burn areas prone to mudslides as an atmospheric river storm pumped drenching rains into Southern California, while blizzard conditions buried the Sierra Nevada in snow. The storm took aim Thursday like a massive firehose at the central coast, where total rainfall over two days neared 14 inches in San Luis Obispo County.  Across the state in the Eastern Sierra, Mammoth Mountain ski resort reported more than 7 feet of new snow on its summit, and blizzard warnings persist along both sides of the California-Nevada border.last_img

Update on Derek Hough’s Injury & Spring Spectacular Schedule

SNL Data Dispatch: U.S. Coal Companies Tightening Supply in Face of Bankruptcies

first_imgSNL Data Dispatch: U.S. Coal Companies Tightening Supply in Face of Bankruptcies FacebookTwitterLinkedInEmailPrint分享By Taylor Kuykendall and Arsalan Gul in SNL:The latest coal miner employment and production data indicates producers took huge steps towards a long-sought and much-needed tightening of domestic coal supply with those undergoing restructuring cutting the most production.A coal supply overhang across the U.S. has kept a lid on prices as demand has rapidly dropped off due to natural gas competition, environmental regulation and mild weather patterns decreasing electricity demand. The state of the market has been particularly troublesome for the debt-laden companies now going through bankruptcy reorganization due to unrealized expectations on global metallurgical coal demand.A new S&P Global Market Intelligence analysis of production data shows that some of the nation’s top producers have accelerated their own efforts in supply rationalization in the past few quarters. Three companies that own some of the largest mines in the nation – Peabody Energy Corp., Arch Coal Inc. and Alpha Natural Resources Inc. — have also brought the largest amount of coal offline, on a quarterly basis, since the fuel’s near-term production peak in the fourth-quarter of 2011. All three companies are currently going through bankruptcy reorganization.Environmentalists and other activists have been highly critical of coal companies in bankruptcy. In a recent report, Public Citizens called on CEOs of bankrupt coal companies to divert bonuses they have received toward laid-off coal workers affected by declining production. They claim it is bad business decisions on management’s part that have landed the companies in their current position.“It is unfortunate that the political discourse has been framed by this fictitious ‘war on coal’ narrative, when the truth reveals an industry hampered largely by market forces and poor financial decisions,” said Tyson Slocum, director of Public Citizen’s Energy Program. “We need an honest dialogue about the future of our energy system and how to prioritize investing in coal mining communities that have been hurt by the transition.”The data analysis groups mines by current ownership, therefore production cuts over the period at mines that were bought and sold are attributed to the current owner.Mines currently owned by Peabody have cut 21.8 million tons of coal output between the 2011 near-term national peak in coal production and the first quarter of 2016, about 40.1% lower. Peabody recently secured approval for its debtor-in-possession financing as it prepares to readjust to current market conditions.“This marks another important step as we move through the Chapter 11 process and reposition the company for long-term success,” Peabody President and CEO Glenn Kellow said in a recent press release.Respectively, Arch and Alpha mines produced 17.1 million tons and 13.4 million tons fewer in the most recent quarter than the near-term nationwide peak in coal production.Companies that have not filed bankruptcy are also responding to a market signal to cut back on production. Cloud Peak Energy Inc. mines produced about 49.2% less coal in the first three months of 2016 than it did when U.S. quarterly coal production peaked. Peter Kiewit Sons’ Inc. produced about 66.3% less coal in the period.“We’re currently a non-profit,” Cloud Peak President and CEO joked at a recent hearing on potential reforms to the federal leasing process. In remarks in opposition to potential reforms that could make it more difficult or expensive to mine on federal lands, a large piece of Cloud Peak’s business, Marshall emphasized that coal is already in a tight spot.“With most federal coal producers bankrupt, coal prices at historic lows and taxes and fees on Powder River Basin coal alone at over 40% of the selling price there is no economic justification whatsoever to increase royalties or lease rates,” Marshall said. “To put this in context, last year Cloud Peak Energy paid $303 million in taxes and royalties when our business suffered a net loss of $204 million.”Other companies that currently own mines where there have been major supply cuts include Murray Energy Corp.,Virginia Conservation Legacy Fund Inc., Rosebud Mining Co., Revelation Energy Holdings LLC, Texas Energy Future Holdings and Westmoreland Coal Co.Full article $: https://www.snl.com/web/client?auth=inherit#news/article?id=36514802&KeyProductLinkType=4last_img read more
