    It would appear it's not a laser shrimp at all but that's how I remembered it so kudos to Gbear for the sensationalism.

    May I present turritopsis nutricula aka the Immortal Jellyfish.

    Yeah that jellyfish is fairly f1ckin cool. Just spent the last few mins typing a response (which I accidentally deleted due to unworkable fingers, grrr.) to the shrimp problem. ie. that they both have numbers measured in kelvin in their wikipedia entries and are called "similar". How do we know which is best? :eek: Calling on mathematicians everywhere.........??

    I'll see your shrimp and raise you any encysting bacteria. They literally freeze-dry themselves until growth conditions are favourable again, and they're near impossible to kill until then. Seriously the amount of radiation you need to reliably kill them is more than enough to wipe out a country or two.

    Pah, encysting bacteria. Here's an animal that can survive in spaaaaaaace

    Water bears
    Tardigrades can withstand temperatures from just above absolute zero to well above the boiling point of water. They can survive pressures greater than any found in the deepest ocean trenches and have lived through the vacuum of outer space. They can survive solar radiation, gamma radiation, ionic radiation— at doses hundreds of times higher than would kill a person. They can go without food or water for nearly 10 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce.

    Aaah aren't they cute.

    Fine, be that way. But happy are those who have not seen, and yet believe. :pac:

    To be fully accurate, I meant endospore-forming bacteria. Although bacterial cysts are tough, endospores are the daddies of badass survival. You can kill them with bleach, but you need to drown them for over 5 minutes, and if the bleach is too strong you'll actually help them survive, too weak and they won't feel it. They can be boiled for hours without dying*. Researchers have found spores that are about 40 million years old, still ready to bounce back, and really, really resistant to radiation.

    *This is why autoclaves were invented. A combination of heat and high pressure is surprisingly effective. Still not 100% though. Even the most sterile equipment is really just highly unlikely to have any surviving cells/spores on it. And even then bits of dead cell can cause an immune response and kill someone.

    It certainly makes you think about the process of life in new and interesting ways. And causes you to feel unreasoning fury at people who try to market some as good and some as bad when they're really just in the wrong place.

    I dunno, the jellyfish is ultra awesome but it's well out-cuted by the tiny wee cratur. I'm going to have to make a sculpture out of it. A BIG waterbear moss piglet.

    Check this stuff out, Carbon Aerogel

    http://www.bbc.co.uk/news/science-environment-22079592

    http://www.huffingtonpost.com/2013/04/02/lightest-material-earth-carbon-aerogel_n_2980978.html

    Chinese scientists have created the world’s lightest substance -- a material so insubstantial it can perch on the petals of a delicate flower without crushing them (see photo above).

    A cubic centimeter of the record-setting stuff, carbon aerogel, has a mass of only 0.16 milligram, according to a new study by scientists at Zhejiang University. That’s 12 percent lighter than an equal volume of the previous record-holder, a substance known as aerographite.

    Having trouble getting a handle just how light this new stuff really is? If the average human body were made entirely of carbon aerogel instead of flesh and bone, it would weigh only 1/40th of a pound!

    As all of you Western Running-Dog Imperialist Lackeys know, Google Earth is a tool for our glorious spy agencies, many of which are christian.

    So, Iran has announced plans to create an "Islamic Google Earth":

    http://www.guardian.co.uk/world/2013/apr/10/iran-plans-islamic-google-earth

    Local media claims that Mohammad Hassan Nami, the senior politician who announced the plan, studied something called "political geography" in Iran and graduated with a PhD in "country management" from Kim Il-sung University in North Korea.

    Bet you didn't know that "knowing things" is a form of fascism? Neither did Robin Ince:

    http://robinince.wordpress.com/2013/04/14/the-fascism-of-knowing-stuff/
    Robin Ince wrote:
    Last weekend I spent some of my time drinking beer and talking to Sir Peter Blake about Kendo Nagasaki. This weekend I spent an hour biting into a pen like a shire horse as my brain failed to comprehend a journalist I was sitting next to. I was at QEDcon, on a panel entrusted with the subject "Is Science the New Religion?"

    It is the sort of title popular with media folk, like "is comedy the new rock and roll?" or "is knitting the new psoriasis?"

    The answer to "is science the new religion?" is obviously yes, so long as you redefine religion as "a self-correcting, evidence based system of exploring the universe which attempts to unearth the least wrong laws and theories that can explain what exists or might exist whilst accepting that room must always be left for doubt and further enquiry".

    We went off topic pretty soon when the journalist explained that politicians, crippled by uncertainty, were now led by behind the scenes scientists. Whether true or not, the actual evidence offered seemed scant. Something about secondhand smoking and something else about education policy. From my view it seemed that the most that was actually being offered was the idea that MPs might cherry pick data to justify the policies they wished to put into place. This seemed very different to the notion that a muscular cabal of scientists are leading the nation into a dictatorship of evidence under the heavy hand of advanced critical thinking. I won't dwell on my disagreements with the journalist's position, hopefully a recording will be available soon and you can make your own judgements and throw a virtual egg or tomato at me via the means of futuristic communication.

    Though I spent much of time either startle-eyed or furiously furrowed, as if an invisible Duchenne was experimenting on my face, there was one opinion expressed that continues to haunt me. There is a gaggle that seems to consider that expertise is an unfair advantage, that all opinions are equal; an idea that people who are experts in climate change, drugs or engineering are given unfair preference just because they spend much of their life studying these things. I do not think it is fascism that heart surgeons seem to have the monopoly of placing hands in a chest cavity and fiddling with an aorta. Though I have my own opinions on driving, I have decided to let others do it, as I have never taken a lesson. I do not consider myself oppressed by the driving majority. I own an umbrella and a thermometer, but I do not believe this is enough to place me on a climate change advisory body.

    I attempted to explain to the journalist that the world we live in has never been more complex or filled with things that require work and patience to understand. Though democracy lovers may shiver at the idea, the penalty for living in the civilisation we currently walk through is that we must sometimes accept our ignorance and defer to others. We can hope that they might be trusted, that the heart surgeon is sober and the climate scientists isn't swayed by the desire for fame on the front cover of Vanity Fair kissing a Polar Bear.

    The journalist suggested this was the kind of fascistic thinking that held up women's suffrage and the education of the poor. My belief that we are not always equipped to make the best decisions is apparently the alibi that has always been used by people like me who wish to oppress "the common man". I believe that people should be given as many tools as possible to understand as many complexities of the world as possible, to be armed with knowledge. As William H Calvin wrote, "knowledge is a vaccine".

    But to blithely suggest that that the world is not complex, that expertise is not only not required but a form of oppression, seems to be a position that can only be taken if you are blinkered when progressing through 21st century society. Go back one hundred years and I believe that pretty much any tool or device in your house could be repaired by you with a little ingenuity and swearing. Look at what you have around you now. Look at the device you are reading this on or your television or mobile phone or digital radio, when they cease to function correctly I wonder how many of you would confidently turn to your toolbox, uncover the technology within and effectively repair it. When I picked up the journalist's ipad, something which seemed to alarm him as if I was a Hyde-ish brute (and I almost was) and declared "mend this", no answer came forth. Go back a couple of hundred years and there was something closer to a democracy of experts, the downside of this was that medical people couldn't cure you, the streets had considerably more human excrement in them and life was often cold and short. The price of technology, comfort and hopefully greater understanding of the universe and our place in it is an acceptance that we may not know best in all events and common sense, a hammer and a bag of leeches may not get you through it all.

    We should not trust people just because they are experts, but if we are not prepared to put the time and effort in to understand something, to take a step beyond that column we read in The Guardian or "what my friend Phil told me", then we are placed in a position where must defer and try and make the best decision we can as to who we should defer to. If you are really interested in an issue, then you must take time to read and investigate it, to learn how to ask the best questions, to interrogate with interest, open-mindedness and rigour. A good society, a healthy democracy, is not based on complacency and whining.

    This morning's Start the Week on Radio 4 (listen here) has Steve Jones talking about his new book 'The Serpent's Promise' in which he revisits questions posed in the Bible in the light of modern science. Also taking part are Adam Rutherford, who has a book on the origins of life and the future of genetic engineering, and Barbara Sahakian talking about smart drugs.

    Steve introduces his book here:


    I've not yet got hold of a copy, but will put that right soon.

    Deep in Siberia's Taiga forest is Vissarion, a cult leader who looks like Jesus and claims to be the voice of God. He's known as "the Teacher" to his 4,000 followers, who initially seem surprisingly normal. Over time, however, their unflinching belief in UFOs and the Earth's imminent demise made this group start to look more and more like some sort of strange cult.

    While perusing d'interweb I came upon this lot:

    Project Steve.

    A group of anti-creationist scientists who all have 'Steve' or recognised cognates such as Stephanie, Esteban, Istvan, Stefano, or even Tapani — the Finnish equivalent) as their first name.

    Their 1000th 'Steve' was Steve Darwin, professor of ecology and evolutionary biology and director of the herbarium at Tulane University.

    Cohen and his colleagues diagnosed that the women were infertile because they had defects in tiny structures in their egg cells, called mitochondria.
    So these kids have two types of mitochondrial DNA. I could be wrong, but I think future (naturally conceived) generations will only arise from gametes containing the "fertile type". In effect then, the doctor has "cured" the family of a genetic ailment, which would otherwise have caused the family to become extinct!
    Interesting that this happened in 2001 but wasn't widely publicised back then. I'd be surprised if some other genetic modifications haven't been tried since then by somebody, somewhere.

    The F-1 engine which powered the moonshots was initially designed on paper, but subsequently heavily modified and the final designs were never recorded.

    Here's the story of how the design of the F-1 was reverse engineered:

    And an intriguing paper on arXiv:

    http://arxiv.org/abs/1304.3381

    The fossil record indicates that applying Moore's law to the complexity of DNA suggests that it's been doubling something like every 380m years, with a start-point 9.7b years ago.

    This is billions of years before the sun was formed, implying that not only are we made from star-stuff, but our ancestors were living there too.

    How insanely neat is that?
