Young Galaxy Cluster Already Mature

first_img“Isn’t that special.”  The remark, in common parlance, is a generic way of avoiding a judgment call.  When astronomers were confronted with the sight of a galaxy too mature for its age, reported the response: “And that makes it special, researchers said.”    The headline was, “Surprise!  Ancient Galaxy Cluster Still Looks Young.”  Actually, that is backwards.  It should read, “Young Galaxy Cluster Looks Mature.”  The import of the story is that a remote mature-looking cluster has been found, dating from a time, according to big-bang cosmology, when the universe was in the adolescence of its presumed 13.7-billion-year age.  “The surprising thing is that when we look closely at this galaxy cluster, it doesn’t look young,” an astronomer said; “many of the galaxies have settled down and don’t resemble the usual star-forming galaxies seen in the early universe.”    The cluster, labeled CL J1449+0856, was observed by the European Southern Observatory’ Very Large Telescope (VLT), at the Paranal Observatory in Chile.”  It had “all the hallmarks of being a very remote galaxy cluster,” but looks like “a mature object, similar in mass to the Virgo Cluster, the nearest rich galaxy cluster to the Milky Way, researchers said.”  They based their age estimate on the cluster’s ability to trap hot gas near its center – gas that gives off characteristic X-rays.    How to explain the anomalous age? quoted Raphael Gobat from Paris:“These new results support the idea that mature clusters existed when the universe was less than one quarter of its current age,” Gobat said.  “Such clusters are expected to be very rare according to current theory, and we have been very lucky to spot one.  But if further observations find many more, then this may mean that our understanding of the early universe needs to be revised.”Gobat did not explain why any mature galaxies would exist at that young age, or how any theory predicted how rare they might be.  One thing they agreed on, though, was that the cluster’s maturity “makes it special.”This announcement is another in a long tradition of anomalous sightings of early maturity (01/08/2002, 09/21/2005, 04/02/2009).  It’s like finding an old man in the maternity ward (10/14/2005).  If this keeps up, the infants in the maternity ward are going to be the “special” ones.  Yes indeed; if that happens, “this may mean that our understanding of the early universe needs to be revised,” Gobat said, going to bat for his colleagues.  The dubious word there is understanding.  Do revisions include overhauls or scientific revolutions?  And to whom does his pronoun our refer?  Maybe some mavericks already have more understanding not at risk of revision.(Visited 14 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Things to know before buying LibertyLink soybeans for next year

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Continued problems with marestail and ragweeds this year have a number of growers considering the switch to LibertyLink soybeans for 2017. The LibertyLink system can certainly be a good choice for management of glyphosate-resistant populations of these weeds, along with waterhemp and Palmer amaranth. It’s essential to use the appropriate approach to LibertyLink soybeans to get the most out of it and avoid potential problems. Some things to consider as you make seed-buying decisions and think about your herbicide costs for next year:• The active ingredient in Liberty — glufosinate — is available in a number of products now. The glufosinate products that are listed in this year’s weed control guide, Liberty, Cheetah, and Interline, have similar loading, rates, and labels. There is also a premix of glufosinate and fomesafen, Cheetah Max, that could be helpful for bigger ragweeds or waterhemp.• POST glufosinate applications in LibertyLink soybeans should be part of an overall comprehensive herbicide program that includes a preplant herbicide treatment containing effective burndown herbicides and broad-spectrum residual herbicides. Do not shortcut the burndown program on marestail and other weeds and expect the POST glufosinate treatments to clean up a less than weed-free start. The POST glufosinate should be targeted for weeds that eventually emerge through the residual herbicides. Also avoid use of glufosinate in the burndown treatment, since this can limit how much glufosinate can ultimately be applied POST.• Omitting residual herbicides from LiberyLink soybeans is generally a good way to ensure problems. Any number of residual premix products can fit into the LibertyLink system. Glufosinate can be weak on lambsquarters, larger pigweed species (including waterhemp and Palmer), and certain grasses — yellow foxtail and barnyardgrass. The residual herbicides should cover these broadleaf weeds for sure, which is not a problem for most premix products. Residual activity on ragweeds and marestail is also desirable. With regard to marestail, our current recommendations for Roundup Ready soybeans are to use several non-ALS herbicides and higher rates, with the goal of not having to treat marestail POST. It’s probably not necessary to go to extremes on the residual program in LibertyLink, since the POST glufosinate can control later-emerging marestail.• Avoiding problems with POST grass control in LibertyLink soybeans can be achieved in one of two ways: 1) use a residual herbicide premix with substantial activity on annual grasses; or 2) include a grass herbicides such as clethodim or Fusion in the POST glufosinate application. The latter approach may be most cost-effective and will also control volunteer corn, which often is not adequately controlled by glufosinate alone. This has become a routine practice for some growers and dealers to ensure effective grass control.• Use of comprehensive residual herbicides usually creates a situation where one POST application of glufosinate is sufficient on many weeds. One exception is giant ragweed, which is best managed with two POST applications — the first when ragweed is 4 to 10 inches tall, and the second about three weeks later. Unless the ragweed population is very low, trying to get by with one glufosinate POST application will mean having to treat large plants that glufosinate can fail to control, which then regrow into late-season. Our research with giant ragweed clearly shows that the best approach for reducing populations is to bite the bullet and make two POST applications for several years (in rotation with an effective corn program), after which it may be possible to make one application work.• POST application timing on waterhemp and Palmer amaranth is also an issue. For these weeds, the preplant residual herbicides should have substantial activity, and the POST glufosinate should be applied to small plants – less than 4 inches tall. A residual herbicide such as Zidua, metolachor, or Warrant can be included with the POST to minimize the need for a second POST application.• Glufosinate is a contact herbicide, and it’s essential to optimize the application parameters to ensure maximum activity. Labels specify a minimum application volume of 15 gallons per acre, and some applicators have found 20 gallons per acre to be more effective. Nozzle and adjuvant selection should be geared toward production of primarily medium-sized droplets, avoiding a nozzle droplet distribution that is biased too much toward fine or large droplets. Applying in volumes too low is another good way to have problems with the LibertyLink system.• Glufosinate activity can be reduced in cool, cloudy conditions, and there can be a need to base application decisions on weather. Many applicators try to apply primarily during periods of relatively warm and sunny weather to avoid performance problems. Using enough residual herbicide should result in enough flexibility in the POST application window to manage weather issues.last_img read more

Farm groups weighing in on WOTUS

first_imgShare Facebook Twitter Google + LinkedIn Pinterest The 2015 version of the Waters of the U.S. (WOTUS) rule must be permanently rescinded, and the prior version of the regulation re-codified, to provide certainty for dairy farmers, the National Milk Producers Federation (NMPF) said.In comments submitted to the U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (ACE) this week, NMPF outlined its support for both agencies’ proposal to repeal the current definition of WOTUS and rewrite it to reflect common-sense approaches to protecting the environment. In addition, NMPF joined numerous farm and food organizations to submit an additional 22 pages of comments that provided an extensive legal and technical assessment of what the two agencies did wrong three years ago in an attempt to update the regulation.“Dairy farmers undertake extensive efforts to manage the natural resources that are critical to their livelihoods,” said Jim Mulhern, NMPF President and CEO. “WOTUS must provide proper clarity on what falls under its jurisdiction so that farmers can better meet the industry’s shared commitment to clean water.”In early 2017, the Trump Administration ordered a review of the WOTUS rule in response to concerns many farm groups had raised since the measure was finalized in 2015. Because the WOTUS regulation significantly expanded the EPA’s authority over waterways used by farmers for drainage and irrigation, the measure was challenged in a federal appeals court and ultimately put on hold.“The 2015 Rule should be repealed and, for absolute clarity, done so permanently,” NMPF said. “We believe the 2015 rule failed to provide regulatory certainty and consistency and exceeded the Agencies’ legal authority under the [Clean Water Act].”The Clean Water Act (CWA) of 1972 gave the federal government jurisdiction over navigable waters but left the regulation of non-navigable waters to the states. However, over the years, the federal government has continually and wrongfully expanded its authority over these non-navigable waters, according to NMPF.NMPF said the two agencies need to apply the definitions of the WOTUS rule in ways that are consistent with recent Supreme Court decisions and long-standing farming practices. Re-codifying the regulations that existed before the 2015 rule was developed will provide continuity and certainty for dairy farmers, other regulated entities, states governments, agency staff, and the public, the comments said.The EPA and ACE should proceed with a notice-and-comment rulemaking process, in which two agencies re-evaluate the definition of WOTUS. NMPF said this must be done to correct the 2015 rule’s lack of clarity on key terms, such as “adjacent,” “floodplain,” and “significant nexus.” Dairy producers must be able to understand what constitutes federally-regulated waters of the United States, so they can better manage water quality on their farms.With the repeal docket now closed, it is likely that the 2015 rule will be repealed permanently. NMPF will now focus on suggesting modifications to the pre-2015 rule and how it can be changed to provide the necessary clarity and certainty.last_img read more

Why Would Microsoft Invest $3 Billion Into Dell?

first_imgRelated Posts 3 Areas of Your Business that Need Tech Now Microsoft may be planning to invest between $1 billion and $3 billion into Dell as part of a leveraged buyout that would take the company private, CNBC reported Tuesday. The report claims that Silver Lake Partners is acting as matchmaker, negotiating an investment between Dell and a special committee representing Dell’s shareholders. The Wall Street Journalconfirmed CNBC’s report, suggesting that any Microsoft investment could be on the order of a couple billion dollars. Microsoft and Silver Lake’s relationship dates back to May 2011, the WSJ reported, as the equity group architected the $8.5 billion deal for Skype.(See Secrecy: The Real Reason Taking Dell Private Makes Sense.)Dell has been said to be negotiating a deal that would take the company private, valued at about $23 billion to $24 billion. Under the new ownership, Dell would be owned by founder Michael Dell as well as Evercore Partners and Silver Lake, according to Bloomberg. Mr. Dell himself owns about 15.7% of the company’s shares, worth $3.45 billion at today’s deflated prices.Dell, of course, made its mark by stripping costs out of the PC supply chain and persuading customers to pay up front for a personal computer that it hadn’t even built yet. Over time, however, the trend of PC commoditization it helped establish caught up with the company, and the balance of power in PC manufacturing has swung toward Asian countries with lower labor costs.So Why Microsoft?Microsoft, of course, is facing its own pressures, as customers shift away from Windows and to smartphones and tablets. Under this scenario, one analyst explained, Microsoft would essentially be buying a customer base. And with $5 billion in cash on hand at the end of the September quarter, Microsoft could theoretically afford it.“Microsoft, with a $3 billion investment, would get a certain amount of control and influence over Dell,” wrote Patrick Moorhead, a former corporate fellow with AMD and now principal of his own analyst firm, Moor Insights, in an email. “Dell has pulled back from the PC business as of late and that is not good for Microsoft as its cash cow is Windows. An investment of this size could guarantee a longer term Windows customer.”Dell, unfortunately, has never had much luck in either tablets or smartphones. After periodically trying and failing to launch a tablet and phone, the company has always returned to its bread-and-butter product: the PC.It’s not hard to believe that Microsoft might also be trying to pursue the sort of deal that brought Motorola under Google’s fold. Ironically, Google has done everything but tap into Motorola’s manufacturing; the word was that Google bought Motorola for its patent portfolio, and every Nexus device that Google announces without a Motorola logo on it gives more credence to that theory.Today, however, Dell is more than just an expert in cost-cutting; the company has been working hard to beef up its services business. And cost-cutting is a service: in a meeting last week, Tracy Davis, vice president of Dell’s data-center solutions group, explained that if customers wanted to build Open Compute servers based on the Common Slot or “Group Hug” board, they should turn to Dell – the only company with the global supply-chain expertise to search out the best deals.Misery Loves CompanyBut if the PC really is on the wane, just as desktops eventually gave way to laptops and so on to tablets, then a Microsoft-Dell relationship might by trying to prop up a pair of companies facing the same underlying problems. It’s a little hard to believe that a company as large as Dell would go out of business, but to that I would say two words: Creative Technology. More than a decade ago, the company’s sound cards were in virtually every PC. Then sound functions became integrated into PC motherboards and processors and the company’s music business was steamrolled by the Apple iPod. Today, Creative Labs, its U.S. subsidiary, sells the sort of headphones you can find in the back aisles at Target.Microsoft hasn’t commented on any particular investment, and I don’t expect it to. But with the company’s quarterly earnings call due Thursday, Wall Street analysts will undoubtedly broach the subject, especially if Microsoft has nothing to say before then.Image source: markhachman IT + Project Management: A Love Affaircenter_img Massive Non-Desk Workforce is an Opportunity fo… Cognitive Automation is the Immediate Future of… Tags:#dell#Microsoft last_img read more
