Governor Mike Dunleavy’s request to extend the disaster assistance registration period for individuals or households impacted by the November 30th Cook Inlet Earthquake has been approved by the Federal Emergency Management Agency (FEMA). Facebook0TwitterEmailPrintFriendly分享The Alaska Senate today unanimously approved funding to aid communities impacted by the November 30 Southcentral earthquake. The extension means survivors now have until May 31, to submit their application to FEMA or the Small Business Administration. The initial registration period would have ended on April 1.center_img Governor Dunleavy: “The spring thaw may uncover earthquake damage to southcentral homes that had previously gone undetected, or will be exacerbated by thawing ground. The extension gives property owners time to look for new or hidden damage, apply for federal disaster assistance, make the necessary repairs and get their lives back in order. I also want to thank FEMA officials for understanding Alaska’s arctic conditions and for approving my request within a matter of days.” Anyone impacted by the earthquake may register at 1-800-621-FEMA (3362) or online at www.disasterassistance.orglast_img read more

first_imgUS Defence Secretary James Mattis (L) welcomes Chinese Minister of National Defence General Wei Fenghe to the Pentagon in Arlington, Virginia, US, on 9 November 2018. Photo: ReutersStanding side by side, top US officials urged their Chinese counterparts on Friday to halt militarisation of the disputed South China Sea, drawing a rebuke from the Chinese for sending US warships close to islands claimed by Beijing in the strategic waterway.During a round of high-level talks in Washington, the two sides aired in sometimes blunt terms many of their main differences, including a bitter trade dispute, freedom of navigation in Asia-Pacific waters, self-ruled Taiwan, and China’s crackdown on its Muslim minority.Two visiting senior Chinese officials also seized the opportunity to warn publicly that a trade war between the world’s two largest economies would end up hurting both sides and to call for keeping channels of communication open to resolve an issue that has unsettled global financial markets.Despite the airing of grievances, the talks appeared aimed at controlling the damage to relations that has worsened in recent months and at paving the way for an encounter between US president Donald Trump and Chinese president Xi Jinping at the Group of 20 summit in Argentina at the end of November.”The United States is not pursuing a Cold War or containment policy with respect to China,” US Secretary of State Mike Pompeo told a joint news conference.Even as the United States and China confront difficult challenges, “cooperation remains essential on many issues,” he said, citing efforts to persuade North Korea to abandon its nuclear programme.The meeting paired Pompeo and defence secretary Jim Mattis with Chinese Politburo member Yang Jiechi and defence minister Wei Fenghe. The annual US-China Diplomatic and Security Dialogue was originally set for Beijing last month but had been called off amid rising tensions.Pompeo took aim at China over its continued building of military installations on artificial islands and reefs in the South China Sea, where China insists it has sovereignty despite competing claims from some smaller neighbours.“We have continued concerns about China’s activities and militarisation in the South China Sea,” Pompeo said following the talks. “We pressed China to live up to its past commitments in this area.”Yang said China was committed to “non-confrontation” but that Beijing had the right to build “necessary defence facilities” on what it considers its own territory and urged Washington to stop sending warships and military planes close to the islands that Beijing claims.Mattis made clear that this demand go unheeded by Washington, which insists it is acting under international law to preserve access for it and others to the South China Sea.TaiwanResponding sharply to Pompeo’s mention of Taiwan, which China considers a wayward province but which is armed by Washington, Wei said Beijing would defend its claim on the island “at any cost.”But Wei and Mattis agreed on the need to lower US-China military tensions to avoid unintended clashes, with the Chinese general saying confrontation “will spell disaster to all.” Washington has protested to Beijing about recent behaviour by its warships that the US Navy considered unsafe.While Pompeo spoke little about trade in his public comments, Yang said he hoped the two sides would find a mutually acceptable solution on the issue “before long.”China and the United States have slapped tariffs on hundreds of billions of dollars of each other’s goods, jolting global financial markets, and Trump has threatened to set tariffs on the remainder of China’s $500 billion-plus exports to the United States if the trade dispute cannot be resolved.Trump’s administration has also accused China of meddling in US politics ahead of this week’s congressional elections, charges China strongly denies.Reflecting growing US concerns about the Chinese cyber threat, a senior US intelligence official on Thursday accused China of violating a 2015 agreement aimed at stopping cyber espionage through the hacking of government and corporate data.Pompeo also reiterated US criticism of China’s “repression of religious groups,” citing treatment of Buddhists in Tibet and minority Uighur Muslims in the Xinjiang region that has drawn condemnation from human rights groups.Yang defended China’s policies in Xinjiang as measures against “ethnic separatist activities and violent terrorist crimes” but said it was a Chinese internal affair and foreign governments should not interfere.last_img read more

first_img As all those who have taken very many chemistry courses know, the Haber-Bosch process involves heating a potassium-doped iron catalyst under high pressure, then mixing it over with hydrogen gas to generate the end product, ammonia.What Holland and his team are trying to do is recreate the same process using a different catalyst. Instead of the regular iron catalysts used in current processes, they would like to use a soluble iron catalyst, which most agree would allow for the process to work under room temperatures. Unfortunately, work by others in trying the same thing has thus far resulted in less than dramatic results, i.e. not enough ammonia was produced.This new research however looks more promising. What the team has done so far is develop a new iron material that will react with nitrogen gas when exposed to potassium which generates a material that has two nitrides which contain a mixed iron nitride core – which will react with hydrogen gas to create a reasonably large amount of ammonia.While this doesn’t exactly solve the puzzle of how to get the H-B process to work at room temperature and at normal pressure (because the iron is consumed, thus it’s not truly catalytic) it is a step in the right direction, and the team is optimistic that because of knowledge gained in their experiments, they will be able to build a complex that is truly catalytic, which will then lead to a real solution to the underlying problem. (PhysOrg.com) — The Haber-Bosch process, known throughout the world as the means by which ammonia is made for use in fertilizer, has been under study for at least as long as the agricultural revolution has been underway. While the current system clearly works, it’s been used to feed the billions of people on the planet for the past several decades; it’s also costly due to the high temperature and pressure involved. If a way could be found to produce the same result at non-elevated temperatures, the production costs would come down dramatically resulting in reduced food prices the world over. No small thing considering we just welcomed the seven billionth person just last week. The good news is that some progress is being made. Patrick Holland and his colleagues at the University of Rochester, and at the Max Planck Institute in Germany, describe in their paper published in Science, how they have been making inroads into using a soluble iron compound to promote the process.

DOI: 10.1126/science.1211906ABSTRACTThe most common catalyst in the Haber-Bosch process for the hydrogenation of dinitrogen (N2) to ammonia (NH3) is an iron surface promoted with potassium cations (K+), but soluble iron complexes have neither reduced the N-N bond of N2 to nitride (N3–) nor produced large amounts of NH3 from N2. We report a molecular iron complex that reacts with N2 and a potassium reductant to give a complex with two nitrides, which are bound to iron and potassium cations. The product has a Fe3N2 core, implying that three iron atoms cooperate to break the N-N triple bond through a six-electron reduction. The nitride complex reacts with acid and with H2 to give substantial yields of N2-derived ammonia. These reactions, although not yet catalytic, give structural and spectroscopic insight into N2 cleavage and N-H bond-forming reactions of iron.

first_img No peak in sight for evolving bacteria Explore further Escherichia coli. Credit: Rocky Mountain Laboratories, NIAID, NIH © 2015 Phys.org One of the foundations of evolution is that organisms change due to challenges they face in their environment, as new challenges arise, those adaptations that best suit the situation are favored, leading to an improvement in fitness. Some prior research has suggested that such adaptations would follow a hyperbolic curve—evidence from this long term effort, suggests that a power-law curve might be more accurate, at least in one such case.The LTEE began in 1988 when a team of researchers at the university, led by Richard Lenski, took a single sample of e. coli, separated it into 12 separate identical flasks held in identical environments and then watched and to see how they might evolve over the years. Periodically, samples have been removed and studied with some being put into deep freeze for later study. Over the past 27 years, the bacteria has produced thousands of new generations—one reached 50,000—offering the researchers a unique opportunity to see evolution in action.In comparing the current generations with the thousands that came before them, the team acknowledged that they fully expected that increases in fitness would level off, and perhaps stop altogether because of the unchanging environment in which they lived—there were no new challenges and all of the samples lived almost exactly the same way. The team did note that there were differences in degrees of sustained fitness among samples in the flasks, but they were minor. They also noticed that while the increases in fitness had slowed over the years, it did not appear to be on a course that would show it stopping at any point. Thus, they suggest it appears to follow more of a power-law curve than anything else. For that reason, the researchers have advised that the experiment continue, allowing future researchers to see if the bacteria will offer any other surprises.

Sustained fitness gains and variability in fitness trajectories in the long-term evolution experiment with , Proceedings of the Royal Society B: Biological Sciences (2015). DOI: 10.1098/rspb.2015.2292AbstractMany populations live in environments subject to frequent biotic and abiotic changes. Nonetheless, it is interesting to ask whether an evolving population’s mean fitness can increase indefinitely, and potentially without any limit, even in a constant environment. A recent study showed that fitness trajectories of Escherichia coli populations over 50 000 generations were better described by a power-law model than by a hyperbolic model. According to the power-law model, the rate of fitness gain declines over time but fitness has no upper limit, whereas the hyperbolic model implies a hard limit. Here, we examine whether the previously estimated power-law model predicts the fitness trajectory for an additional 10 000 generations. To that end, we conducted more than 1100 new competitive fitness assays. Consistent with the previous study, the power-law model fits the new data better than the hyperbolic model. We also analysed the variability in fitness among populations, finding subtle, but significant, heterogeneity in mean fitness. Some, but not all, of this variation reflects differences in mutation rate that evolved over time. Taken together, our results imply that both adaptation and divergence can continue indefinitely—or at least for a long time—even in a constant environment. (Phys.org)—A team of researchers working on Michigan State University’s Long-Term Evolution Experiment (LTEE) has found that even after nearly thirty years living in an unchanging environment, generations of Escherichia coli continue to show improvements in fitness. In their paper published in Proceedings of the Royal Society B, the team describes the nature of their long term experiment and their surprise at the continual evolution of the simple bacteria.
