    Ten-year-old girl gets vein grown from her stem cells

    A 10-year-old girl has had a major blood vessel in her body replaced with one grown with her own stem cells, Swedish doctors report.

    She had poor blood flow between her intestines and liver.

    A vein was taken from a dead man, stripped of its own cells and then bathed in stem cells from the girl, according to a study published in the Lancet.

    Surgeons said there was a "striking" improvement in her quality of life.

    This is the latest is a series of body parts grown, or engineered, to match the tissue of the patient.

    Last year, scientists created a synthetic windpipe and then coated it with a patient's stem cells.

    Home-grown
    A blockage in the major blood vessel linking the intestines and the liver can cause serious health problems including internal bleeding and even death.

    In this case, other options such as using artificial grafts to bypass the blockage, had failed.

    Doctors at the University of Gothenburg and Shalgrenska University Hospital tried to make a vein out of the patient's own cells.

    It used a process known as "decellularisation".

    It starts with a donor vein which is then effectively put through a washing machine in which repeated cycles of enzymes and detergents break down and wash away the person's cells.

    It leaves behind a scaffold. This is then bathed in stem cells from the 10-year-old's bone marrow. The end product is a vein made from the girl's own cells.

    The doctors said: "The new stem-cell derived graft resulted not only in good blood flow rates, but also in strikingly improved quality of life for the patient."

    Profs Martin Birchall and George Hamilton, from University College London, said: "The young girl was spared the trauma of having veins harvested from the deep neck or leg with the associated risk of lower limb disorders."

    They said this one-off procedure needed "to be converted into full clinical trials... if regenerative medicine solutions are to become widely used"

    Scientists Confirm that Plants Talk and Listen To Each Other, Communication Crucial for Survival

    When a South African botanist Lyall Watson claimed in 1973 that plants had emotions that could be recorded on a lie detector test, he was dismissed by many in the scientific community.

    However, new research, published in the  journal Trends in Plant Science, has revealed that plants not only respond to sound, but they also communicate to each other by making "clicking" sounds.

    Using powerful loudspeakers, researchers at The University of Western Australia were able to hear clicking sounds coming from the roots of corn saplings.

    Researchers at Bristol University also found that when they suspended the young roots in water and played a continuous noise at 220Hz, a similar frequency to the plant clicks, they found that the plants grew towards the source of the sound.

    ...

    Scientists suspect that sound and vibration may play an essential role in the survival of plants by giving them information about the environment around them.

    Researchers said sounds waves are easily transmissible through soil, and could be used to pick up threats like drought from their neighbors further away.

    How Trees Communicate (Video)

    Researchers at the University of British Columbia are concluding that trees are interacting with one another in a symbiotic relationship that helps the trees to survive.  Connected by fungi, the underground root systems of plants and trees are transferring carbon and nitrogen back and forth between each other in a network of subtle communication.  Similar to the network of neurons and axons in the human brain, the network of fungi, roots, soil and micro-organisms beneath the larger ‘mother trees’ gives the forest its own consciousness.

    1. Eco-Friendly Environment Invisible Cars

    To promote its upcoming eco-friendly hydrogen powered fuel-cell car, Mercedes-Benz used the phrase “Invisible Cars” as the vehicle comes with the technology for zero emissions on the surroundings and is thus invisible to the environment. Although the development on such cars have been completed, it still demands a couple of years to be publicly launched.
    http://www.youtube.com/watch?v=ZIGzpi9lCck

    2. Space Elevator

    The scientists at Japanese have started development on its innovative technological masterpiece, the Space Elevator, which would take you to above 22,000 miles above the earth.  The elevator would be capable of accommodating 30 passengers with a speed of about 125mph. The journey via Space Elevator would be 8 days long and would finally take you to its space station into the Geosynchronous Orbit.



    3. Driverless Cars

    The engineers at Google recently patented the driverless cars technology and now have successfully tested the vehicles in Nevada. The Google driverless cars technology can be incorporated into any car. Google hopes that the driverless upcoming future technology for cars would definitely make your life much easier while taking the chances of accidents to minimum extent.


    4. Robotic Assistants

    The field of Robotics has been grown too much from the past few years. From cleaning a room to helping a doctor in surgery, the robots have become very smart.  Now a new study predicts that by next decade, this future technology would become a standard that every home would have one robot to handle simple household jobs (super duper Will Smith’s iRobot movie demonstrates the same idea). Foxconn, the China’s largest electronics Industry, also wishes to change its workers with 1 million robots in the next few years.


    5. Mind Reading Computers

    By next decade, IBM expects to make a Mind Reading Computer i.e. a computer that fully according to your thoughts. The user just needs to wear a specialized headset which would interpret the signals from your mind and then send it to the paired computer for next responding steps. Mind-Reading upcoming future technology would be ready within the upcoming three years, as stated by IBM

    Atomic bond types discernible in single-molecule images



    A pioneering team from IBM in Zurich has published single-molecule images so detailed that the type of atomic bonds between their atoms can be discerned.

    The same team took the first-ever single-molecule image in 2009 and more recently published images of a molecule shaped like the Olympic rings.

    The new work opens up the prospect of studying imperfections in the "wonder material" graphene or plotting where electrons go during chemical reactions.

    The images are published in Science.

    The team, which included French and Spanish collaborators, used a variant of a technique called atomic force microscopy, or AFM.

    AFM uses a tiny metal tip passed over a surface, whose even tinier deflections are measured as the tip is scanned to and fro over a sample.

    The IBM team's innovation to create the first single molecule picture, of a molecule called pentacene, was to use the tip to pick up a single, small molecule made up of a carbon and an oxygen atom.

    This carbon monoxide molecule effectively acts as a record needle, probing with unprecedented accuracy the very surfaces of atoms.

    It is difficult to overstate what precision measurements these are.

    The experiments must be isolated from any kind of vibration coming from within the laboratory or even its surroundings.

    They are carried out at a scale so small that room temperature induces wigglings of the AFM's constituent molecules that would blur the images, so the apparatus is kept at a cool -268C.

    While some improvements have been made since that first image of pentacene, lead author of the Science study, Leo Gross, told BBC News that the new work was mostly down to a choice of subject.


    Tiny distortions to the regular hexagonal pattern of carbon bonds is what interests the researchers
    The new study examined fullerenes - such as the famous football-shaped "buckyball" - and polyaromatic hydrocarbons, which have linked rings of carbon atoms at their cores.

    The images show just how long the atomic bonds are, and the bright and dark spots correspond to higher and lower densities of electrons.

    Together, this information reveals just what kind of bonds they are - how many electrons pairs of atoms share - and what is going on chemically within the molecules.

    "In the case of pentacene, we saw the bonds but we couldn't really differentiate them or see different properties of different bonds," Dr Gross said.

    "Now we can really prove that... we can see different physical properties of different bonds, and that's really exciting."

    The team will use the method to examine graphene, one-atom-thick sheets of pure carbon that hold much promise in electronics.

    But defects in graphene - where the perfect sheets of carbon are buckled or include other atoms - are currently poorly understood.

    The team will also explore the use of different molecules for their "record needle", with the hope of yielding even more insight into the molecular world.

    Genetically modified herpes vs severe cancer pain

    Quote
    What happens when the pain gets to be too much?  What happens when the drugs stop working?  The physicians are giving you as much as you can take without dying, and youre still living with 7, 8, 9 levels of pain, every waking moment?  Some of the talk behind physician assisted suicide is to let people decide when enough is enough, and to permanently end their pain-filled hellish existence.

    But what if there were options?

    What if herpes could bring your pain levels down from 7, 8, 9… to 1-2?  What if herpes could take you from ‘I want to end my own life’ to ‘I can handle this’?

    What if I told you this idea is not the mad rantings of an insane virology graduate student, but a reality that has already occurred?

    [Read on]


    How amazing would it be if it's confirmed?

    Anti-ageing pills may be available within a generation

    Quote
    Genetic alterations and diet restriction in animals have been shown to delay ageing by blocking parts of the chemical network in our bodies which co-ordinates everything from growth and metabolism to our reproductive system.
    Some drugs licensed for use in humans, including aspirin and metformin, a common diabetes drug, have already been found to mimic the way these gene mutations and dietary restriction affect our bodies, and have a similar effect.
    Because the treatments tackle the ageing of the body itself, they could also preserve other traits like our muscle strength, hearing and the condition of our skin.

    In the coming decades it may be possible to combine the key active ingredients into a single pill which would protect us against the ravages of age, Dame Linda predicted.
    She said: “What we want is drugs that mimic dietary restriction, and so far we have mainly been finding that drugs that are already licensed for us have a broader impact than people realised.
    “Certainly it looks with dietary restriction as if it can hold off the diseases for longer – with mice we often can’t tell what they died of. It compresses the morbid period at the end of life, the period when things aren’t quite right before death occurs.
