Bacteria and Plants Know Network Tech

first_imgAn article on Science Daily says, “plants have their own chat systems that they can use to warn each other.” Many herbal plants such as strawberry, clover, reed and ground elder naturally form networks.  Individual plants remain connected with each other for a certain period of time by means of runners.  These connections enable the plants to share information with each other via internal channels.So what do they have to chat about?  Danger.  Their “early warning system” enables them when hazards lurk about: “Once warned, the intact plants strengthen their chemical and mechanical resistance so that they are less attractive for advancing caterpillars,” for instance.    Even smaller critters may have networks: in fact, possibly even a power grid.  Phillip Ball wrote for News@Nature, “Bacteria may be wiring up the soil.”  Yes, believe it or not, “Bacteria can sprout webs of electrical wiring that transform the soil into a geological battery, a team of researchers claims.”  Some bacteria extrude “nanowires” that shunt electrons produced during metabolic reactions.  A geochemist working at the Venter Institute believes “The earth beneath our feet might act as a gigantic circuit built by microbes to power their metabolic systems.”  If so, this “new aspect of microbiology” is a little too fantastic for some to accept, but one admitted, “If this idea is right, it is really quite remarkable.”You don’t need to talk to your plants.  They’re too busy text-messaging each other.  Maybe human network engineers could learn a little technology from our humbler lifeforms.(Visited 18 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Darwin Still Rules from the Grave

first_imgDarwin died in 1882, but more than any other scientist, seems to live on in the science news.  Here are some recent examples.  The question is: do any of these articles really have anything to do with the theory that made him famous?  Or is some other dynamic at work that keeps him in the forefront? Darwinian funding:  Science magazine (11 November 2011: Vol. 334 no. 6057 pp. 753-754, doi: 10.1126/science.334.6057.753) lamented how the bad economy is affecting funding at the National Institutes of Health (NIH).  In “Darwinism vs. Social Engineering at NIH,” Jocelyn Kaiser wrote about the competition between labs.  “As National Cancer Institute Director Harold Varmus recently put it, NIH is weighing some type of ‘social engineering’ rather than simply letting ‘Darwinian forces’ cull weaker labs and shrink the number of mouths NIH feeds.”  It sounds like a metaphor of the battle between Intelligent Design and Survival of the Fittest, but surely she did not mean that medical labs are products of random, undirected mechanisms.  [News Flash: Darwinism is not a force.] Darwinian robots:  New Scientist committed a colossal non-sequitur in its short article, “Darwin trumps self-obsession in robotics.”  The point is that creating robots in our own image is doomed to fail.  A new generation of rebel roboticists, the editorial claims, is thinking that robots should be soft and squishy, “inspired by the theory that intelligence emerges from the body.”  Here was the ending non-sequitur: “Crucially, the next generation of robots will not be designed as if by gods – in our image – but by using the principles revealed by Darwin. Once again, evolution has dealt a blow to the idea that humans were created special.” Darwinian emotions:  The only one of these three articles that related specifically to Darwin’s theory was an update on his theory of emotions posted by the BBC News.  The Darwin Correspondence Project is trying to recreate his experiment nearly 150 years later, reporter Stephanie Hegarty wrote, “to test his results, and draw attention to his contribution to psychology.”  Hegarty gave him a pass: “It was somewhat unscientific by modern standards, with no control group and a very small sample, but it was revolutionary for its time.”  Darwin wanted to prove that facial expressions in response to emotion were innate and universal, and that “expression was a trait that humans shared with beasts.”  His results were published in his 1872 book, The Expression of Emotions in Man and Animals.  The BBC News article, however, drew no connection to his hunch and his theory of natural selection; nor did it seek to explain how facial expressions lead to fitness and survival.  Anyway, has the Darwin Correspondence Project replicated the results?  No; it’s a work in progress.  That didn’t stop Hegarty from heaping praise on Darwin with quotes from others who called him “an immense intellect” and “truly a genius” who “formed the basis for an entire canon of psychological study.” Darwinian weapons:  On the premise that “evolution is a simple fact” and “the fact of evolution itself is not disputed by any reputable scientist” (appealing to Coyne and Dawkins as authorities), Paula Kirby at The Washington Post took glee in skewering Christian conservatives as guilty of willful ignorance, because “Evolution Threatens Christianity.”  Without mentioning Darwin directly, she referred to two of his greatest defenders today.  This has long been a legacy of Darwinism: a tool to attack religion – and not just any religion, but Christianity.  Paula Kirby’s screed and New Scientist’s loony non-sequitur are so typical of the Darwin demagogues.  Their notion of scientific “truth” could not withstand a freshman course in philosophy of science.  The modus operandi of their ilk is: (1) hate Christians and conservatives first, then (2) appeal to the authority of Darwin and his disciples to call anyone who disagrees an ignoramus. Charles Darwin is the god of atheists and naturalists, the Bearded Buddha at whose shrine they offer their sacrifices.  For a balance to the worship and adoration given to the B.B. you need to read Jerry Bergman’s eye-opening book, The Dark Side of Charles Darwin (available at Amazon.com).  It’s amazing this troubled con-man ever became famous at all.  For instance, Bergman reveals that his photographs used for The Expression of Emotions in Man and Animals were faked (just one of many scientific sins he committed).  The guy was as bad as Haeckel, but got away with it, because of his gift of gab and manner of carefully cataloguing things to present a façade of scientific rigor, then telling stories that had little or nothing to do with the data or his theory (if it can even be called a theory), winning acceptance through association. Getting Moses out of science was really the goal.  It so appealed to other anti-religious disciples that, with the aid of his X-men like Huxley, they redefined science altogether as naturalism; something like Darwinism, therefore, had to be true – by definition!  Natural history became confabulation, scientific rigor, mortis.  The articles above show that his disciples completely misrepresent his ideas and portray “natural selection” as if it performs intelligent design miracles!  This is insane.  It’s time we expose the fraud of this flawed, disturbed man who has been morphed into a caricature of Moses leading science into a promised land.  They’re not in the promised land; they’re wandering aimlessly in Fantasyland.(Visited 18 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Chaos Monkey: How Netflix Uses Random Failure to Ensure Success

first_imgRelated Posts klint finley Why Tech Companies Need Simpler Terms of Servic… In a post last week about lessons learned using Amazon Web Services, Netflix‘s John Ciancutti revealed that the company built something called “Chaos Monkey” to ensure that individual components work independently. Chaos Monkey randomly kills instances and services within Netflix’s AWS infrastructure to help developers to make sure each individual component returns something even when system dependencies aren’t responding.For example, if the recommendation system is down Netflix will display popular titles instead of personalized picks. The quality of the response is degraded, but least there is a response. Ciancutti explains it this way: “If we aren’t constantly testing our ability to succeed despite failure, then it isn’t likely to work when it matters most – in the event of an unexpected outage.”Here are the lessons Ciancutti writes that Netflix has learned: Dorothy, you’re not in Kansas anymore (“You need to be prepared to unlearn a lot of what you know”)Co-tenancy is hardThe best way to avoid failure is to fail constantlyLearn with real scale, not toy modelsCommit yourselfChaos Monkey fits into number three.For more advice on migrating to the cloud from Netflix, check out our article Netflix’s Advice on Moving to Amazon Web Services. 8 Best WordPress Hosting Solutions on the Marketcenter_img Top Reasons to Go With Managed WordPress Hosting A Web Developer’s New Best Friend is the AI Wai… Tags:#cloud#cloud computing last_img read more

Go Remote with Compact LED Lights

first_imgIf you know you’re shooting with limited access to power, these LED lights can make all the difference.Top image via Shutterstock.If you know you’re headed for one of these shoots and you have to pack light, it might be worth acquiring an LED light that is compact, independently powered, and budget friendly. The keyword is compact; we want to look at lights that can easily fit in your gear bag.The following are the LED lights that I’ve been most satisfied with in various shooting circumstances over the years.The Aputure Amaran AL-M9 — $40The AL-M9 is a 6×9 cm palm-sized light that uses nine integrated LED chips instead of conventional LED bulbs. It’s a very basic light with straightforward options: on-off, increase-decrease brightness. However, compact lights, do not need much more functionality than this, and the AL-M9 really is compact — I can slot it into my wallet along with my debit cards.Despite its size, this LED gets extremely bright. It has a LUX rating of 950 at 0.3 meters and a very high CRI rating of 95.Because of its compact size, you can get creative with the AL-M9’s placement — in the fridge, between books on a bookshelf. You can have an actor hold the light on top of a mobile phone if the character is making a phone call. The possibilities are endless.The AL-M9 also comes with a cold shoe adapter so you can mount it on top of your camera. You just slot the light into the adapter and place it in the cold shoe mount. The adapter also allows you to direct the light to the side, which is essential if you need to bounce the light rather than directly illuminate your subject.ProsIncredibly bright for such a compact deviceComes with a carabiner so you can attach it to your belt or bag for quick access.ConsUSB Charge, no replaceable battery optionNo other filter accessoriesUnable to use with camera without adapter F&V Ultracolor Z96 — Under $100 for the Older Model, Over $100 for the Ultracolor DesignThe Z96 has 64 fewer LEDs than the YN160. However, it does have better color rendering (95). This light retails at $159, although if you look hard enough, you can catch a great deal at lesser-known outlets. Please be vigilant when buying the Z96 and the YN160 from eBay. There are many listings by third-party sellers that are knockoffs. These lights will not have the same build quality or safety measures as their official counterparts.All of these lights are great choices when you’re on the road with limited resources. If you’re flying overseas, the option of buying AA batteries abroad makes life much easier than figuring out if you can take a lithium ion battery on the plane.Do you have any go-to compact lights? Let us know in the comments. Image via F&V.You can also grab the older version (which has a CRI of 85) on the aftermarket. Recent listings on eBay suggest the older model now sells for $60-$75.You can increase the Z96’s brightness in percentages of 10, and it comes with a hot shoe attachment, a diffusion filter, and a tungsten filter. The biggest selling point for this compact LED is that you can connect several units together. Joining four units together will give you a brighter output than the average 1×1 panel! That’s a 1×1 panel that you can store in the top of your gear bag. It’s a great alternative if you don’t have the option to actually bring a light panel to your location.Much like the ML-A9, due to the compact size of this light, you can place this in a variety of creative areas to enhance your shot.In the shot below, the character is seeing the symbolic light of death before her demise. A 300w served as “the light,” and it threw the bookcase into darkness. I placed the Z96 behind the actress on the bookcase and illuminated part of the case, which also pulled the character out of the dark background. This wouldn’t have been possible with a larger light.ProsTriple power option: 5x AA batteries, DC jack, Sony NP-BatteryAttach up to 9 units togetherRobust buildConsOlder model has a terrible flicker rate for slow motionNot that bright in comparison with the others.Expensive YONGNUO LED Video light YN160 — $40-50This portable LED has been around for a while; however, as successors have improved upon this model, the YN160 has become very affordable. You can pick these up on Amazon for under $50. It’s a compact light, but you won’t be able to place this one in your wallet.The YN160 offers more flexibility of placement than the AL-M9. It has four reflective barn doors, sixteen brightness increments, and a filter slot for four filters that come with the light.As the light output isn’t that strong, the YN160 can be ideal as a kicker or fill.Like the AL-M9, the YN-160 comes with a cold shoe mount that you can tilt up and down. It would also be worth acquiring a light stand adapter so you can use these on set.Pros6 x AA batteries or Panasonic CGR-D16S/D220 – Sony NP series rechargeable batteries.Incredibly light1,480 LUX at 1mVery affordableBattery power LED light displayConsNo protective caseNot as bright as newer modelsCheap buildCRI not as high as some modelslast_img read more

Tokyo returns with Summer Games with something new to prove

first_img“And there will be more to come,” Coates said. Typhoon Kammuri accelerates, gains strength en route to PH Read Next This time the Japanese capital wants to remind the rest of the world that China and South Korea haven’t left behind the first economic powerhouse in East Asia. They will use the games to showcase a clean, safe, and innovative city; an urban maze of nightlife, shopping, and dizzying subway lines that give texture to “Cool Japan” and the country’s place as a cultural touchstone.“It’s going to be a good opportunity to showcase Japanese culture, our technology, our products, our good level of service to give impetus to the Japanese economy,” Maki Kobayashi-Terada of the Ministry of Foreign Affairs, told The Associated Press.FEATURED STORIESSPORTSWATCH: Drones light up sky in final leg of SEA Games torch runSPORTSLillard, Anthony lead Blazers over ThunderSPORTSMalditas save PH from shutout“It’s exactly soft power … to create economic impact,” Kobayashi-Terada added, a fancy term that means translating an engaging culture into political and economic power.Tokyo has billed itself as a “safe pair of hands” for the Olympics, which is everything that Rio de Janeiro wasn’t. The 2016 Games left behind scandals, millions in unpaid bills, and useless “white elephant” venues. But exactly what’s in it for Japan?Kobayashi-Terada said the Olympics will improve accessibility for the elderly and for people with disabilities, modernize infrastructure and drive tourism. She said Japan had 29 million foreign visitors last year, and hopes to have 40 million in 2020. Tourism is booming, particularly from Asia.The Olympics will also try to convince the world about the safety of Fukushima, where a nuclear reactor was damaged after the 2011 earthquake and tsunami. The prefecture north of Tokyo is a venue for baseball and softball.“There are only some limited villages which are restricted for entry,” Kobayashi-Terada said. “But there are so many other places which are already under recovery. We’d like to show that and thank the world.”But there also hints of scandal.A French-led investigation has been looking into $2 million paid by the Tokyo Olympic bid team — or representatives — to sports officials who have been linked to vote-buying in IOC bid elections. A Japanese investigation concluded the payments were not illegal.“Our committee is different from the bidding committee,” Kobayashi-Terada said. “We believe that we got Tokyo 2020 because our bid was the best one.”And there are domestic doubters.Japan is already a high-tax country that does not need the Olympics to spur building new bridges, trains and highways. Taxpayers have been critical of too much spending on questionable projects.“Tokyo lacks a clear purpose for hosting the games other than city development, and that’s why many people are still puzzled today,” said Yuji Ishizaka, an expert on the Olympics at Japan’s Nara Women’s University. After 2 lopsided losses to Thunder, Durant leads Warriors rout Families in US enclave in north Mexico hold sad Thanksgiving Ishizaka said people are bothered by delays and scandals involving the redevelopment plans for Tokyo’s world-famous Tsukiji fish market and the city’s bay area, where several events will be held.And Ishizaka fears the Olympics “may be used to declare the end to disaster reconstruction” in the Fukushima area, suggesting things are back to normal.“The 2020 Games should be a big festival, but we can’t expect much growth and many people, even residents of Tokyo, will hardly notice the changes that Tokyo has gone through,” Ishizaka said.The IOC and local organizers say they’re cutting costs. John Coates, the IOC member overseeing Tokyo’s plans, said recently that Tokyo had cut $1.4 billion from the price tag. Some venues have been moved to other areas, and existing venues will be used instead of building new ones.Coates lauded Tokyo’s transparency and mentioned Rio.“In Rio we didn’t know who was paying what — if at all,” he said.Tokyo organizers say the games will cost about 1.35 trillion yen ($12.5 billion). However, last month Tokyo Governor Yuriko Koike said the city would spend an added 810 billion yen ($7.5 billion) on “projects directly and indirectly related to the games.”The IOC and organizers argue those expenditures fall “outside the overall games budget.” This is a debate that rages at every games: Exactly what are, and what aren’t, Olympic expenses?Koike said the new costs included building barrier-free facilities for Paralympic athletes, training programs for volunteers, and advertising and tourism plans.That puts the total cost at about $20 billion, 70 percent of which is public money. This figure includes the privately run local organizing committee’s budget of 600 billion yen ($5.5 billion). About $2.91 billion of that is coming from national marketing program that has landed 47 sponsors. AFP official booed out of forum Tokyo also marks a watershed for the battered International Olympic Committee.After corruption dogged the games in Rio, and a doping scandal grew out of the 2014 Winter Games in Sochi, Tokyo should be the first of three return-to-normal Summer Games in first-world metropolises. The IOC has already picked Paris for 2024 and Los Angeles for 2028.And Japan also has hosted two successful Winter Olympics in Nagano and Sapporo.“I don’t think the International Olympic Committee is going to go to a developing city any longer,” Olympic historian David Wallechinsky told The Associated Press. “They don’t want that anymore. They want cities that are ready.”The Pyeongchang Olympics were Wallechinsky’s 18th, and he has researched every Olympics extensively including Tokyo. Those Olympics kicked off when Yoshinori Sakai — born in Hiroshima the day the city was hit by the 1945 atomic bomb — lit the Olympic cauldron.ADVERTISEMENT Don’t miss out on the latest news and information.
