I thought I might be of some help here, but I'm a bit confused about the long list of sports event announcements. I thought the purpose of the site was to provide assistance and answers for grammatical issues. What's the deal?
Imagine a world in which large-scale man-made structures could assemble themselves, reconfigure themselves or even change their material properties.Architecture alum and lecturer Skylar Tibbits (SM â€˜10, Design Computation; SM â€˜10, Computer Science) is working on bringing that world about by developing â€˜smartâ€™ components that translate natural molecular processes and computational processes into self-assembly technologies for the built environment.Self-assembly is a process by which disordered parts build an ordered structure entirely on their own, a process Tibbits enables by fabricating objects that can respond to various energy sources to change themselves over time.
To formalize this line of inquiry, he recently established the Self-Assembly Lab at SA+P. The increasing complexity of our built environment â€” buildings, machines, computers and almost everything else â€” is creating exponential growth in the intricacy of construction.
skyscraper involves up to a million parts and takes more than two years to assemble; a spaceship involves 2.5 million parts and takes five years to Silver Lotto System review the world of natural systems, there are proteins with two million types that can reconfigure in 10,000 nanoseconds.
And DNA with three billion base pairs that can replicate in roughly an hour.
All with far more efficiency than anything we can build, and with virtually no mistakes.Read

N. Brown, professor of computational neuroscience and of health sciences and technology at MIT, and Warren M. Zapol Professor of Anaesthesia, Harvard Medical School and Massachusetts General Hospital;Recent news revealed that scientists have cloned an extinct frog. But surely there are better animals to resurrect than frogs.
Frogs are rubbishThe recent news that scientists in Australia have successfully inserted the DNA
of an officially extinct frog into a living embryo, effectively creating a living genome and for all intents and purposes resurrecting the species, bringing it back from extinction.This
inevitably led to a lot of reaction and speculation. Many people are referencing Jurassic Park, other Forex Megadroid speculating about the long-term applications of the technique, some are issuing caution, pointing out that the specimens never got past the embryonic stage, so it's early days yet.Undoubtedly, there are many questions to be answered about this process, practical, theoretical, even ethical or philosophical. But there is one question that hasn't been raised yet, and I feel it is an important one.Why
resurrect a frog? It shows how out of touch scientists are when, with all the knowledge and resources at their disposal to further the advancement of mankind, they end up thinking "You know what we need? More bloody frogs!"Frogs are crap.
We were all thinking it, it's time
someone finally just said it.
What good are they? They're mostly famous for croaking, which is hardly an achievement, and a lot of them can't even do that. Seriously, what use are frogs? They eat flies, which are annoying, but that's only useful to us if Penny Stock Prophet. in the swamps alongside them, which humans don't because we're a sensible species.
The only use frogs seem to have is to be dissected by biology students, and that doesn't happen so much these days.They're not even edible. The French have tried to eat them, but they can only manage the legs, and even this is pushing it. And seriously though, what do the French even know about food? They eat horse! Can you imagineâ€¦Frogs are actively disgusting too.
They leave their filthy spawn everywhere, and they actively have sex with dead things. They don't even have to be the same species. And some people may complain that it's a toad in that last link, not a frog, but let's drop that charade shall we? It's fooling nobody.
The difference between frog and toad is no more significant than the difference between "Redhead" and "Ginger". We all know this.The
frog they resurrected is particularly
unpleasant, in Coffee Shop Millionaire review a gastric brooding frog, meaning it gives birth through its mouth. That's not impressive, that's a serious evolutionary cock up. It probably went extinct for a reason. Bringing this thing back from extinction is like scientists in a thousand years having the opportunity to resurrect a small number of present
day humans and
opting for the cast of Jackass.
There's a reason witches turn princes into frogs in fairy tales. The whole species has been downhill since Kermit.So what species should they have resurrected, if not
rubbish frogs? Well, here are some brilliant suggestions. And spare me your arguments about "viable DNA", "biological plausibility" and "logic", you know you'd love to see these roaming the planet again:The Irish elkWhat better celebration of St Patrick's day could there be than reintroducing one of the biggest deer ever to roam Europe.
Their antlers alone would be worth the effort, with them being more than 4m long and about Forex Growth Bot weight. If, like modern elks and moose, their antlers drop off after mating, that would mean they'd just be lying around for enterprising folk to find and utilise as dustbin lids, surfboards or elaborate satellite dishes.
Should the giant animals be as nonchalant around humans as their modern descendants then it may be possible to paint their antlers green (using safe, non-toxic paint, of course) and reclaim the Irish elk for Ireland.MegalodonOriginally,
after my recent Comic Relief piece, I was tempted to say Helicoprion, just to see how a
shark with chainsaw teeth would even function.
But if you're going to resurrect an extinct shark, it really would have to be Megalodon. Some people may say that reintroducing a 60ft long, 40 ton shark with 7 inch teeth and a bite force of up to 18 tons into our oceans would be a tad unwise, but look at it this way; people don't like whaling, and google sniper 2 Megalodon looks just like a whale if you're not expecting it (which nobody should be). The reaction of the crew of a whaling ship when what they thought was a placid
cetacean is in fact 50 tons of furious megashark coming straight at them should be worth the resurrection effort alone. And I imagine Megalodon would find fishing nets little more than an irritation. People are increasingly concerned about the damage humans are wreaking on the sea, so why not level the playing field somewhat?Tyrannosaurus rexSome might see the suggestion of T-Rex as a bit of an obvious one, what with it being the most famous dinosaur and star of the aforementioned Jurassic Park.
But my reasons are different.
I don't care about seeing some long-extinct formidable land predator and cultural icon. I just want to see if it had feathers. That would be brilliant, all these people queuing up to see this legendary fearsome reptile, iPad Video Lessons be confronted by something that resembles what you'd get if the accident that created the Incredible Hulk had happened to a parrot. Quagga Efforts are already in place to bring back the African quagga. To be honest, I don't know a great deal about it, apart from the fact that it's often described as half horse/half zebra. This suggests that if we clone it, we're bringing back two species for the price of one. In these times of austerity and funding cuts, that's nothing to be sniffed at.DodoAnother obvious choice perhaps, but I feel the Dodo has earned it; partly because it probably went extinct because of us (although that's often the case), but mostly because, despite this, we keep mocking the poor creature.
Calling someone a Dodo isn't a compliment, and in the film Ice Age they're portrayed as clueless and reckless to the point of suicidal in comparison to mammoths and sabre-tooth tigers, despite dotcomsecrets that it outlived both of those. So I feel the Dodo should get another chance to prove itself.And in fairness, they do look funny.
We could do with another intrinsically funny flightless bird, if only to give penguins a break.If you're still reading this far, I should probably admit that I don't really have any issue with frogs or toads.
They're undoubtedly an interesting, diverse and impressive class of amphibians, who have contributed much to science and have as much right to exist as any species.
My initial rant was just bitterness, stemming from the fact that I'm still traumatised by finding out it now costs more than 10p for a Freddo.

The latest in a long line of police photos show the 26-year-old actor having a go at her very own Mona Lisa smileNot for the first time in her life, Lindsay Lohan finds herself in front of a police camera.
