    From New Scientist

    SO YOU'VE hitch-hiked through Central America, stalked rare beasts in Madagascar and trekked your way through northern Chile. You're pretty well travelled, even if you do say so yourself. Before you get ideas about being an intrepid explorer, however, consider this. For all their wide open spaces and seeming wildernesses, none of these places can be described as remote in 2009.

    In fact, very little of the world's land can now be thought of as inaccessible, according to a new map of connectedness created by researchers at the European Commission's Joint Research Centre in Ispra, Italy, and the World Bank.

    The maps are based on a model which calculated how long it would take to travel to the nearest city of 50,000 or more people by land or water. The model combines information on terrain and access to road, rail and river networks (see the maps). It also considers how factors such as altitude, steepness of terrain and hold-ups like border crossings slow travel.

    Plotted onto a map, the results throw up surprises. First, less than 10 per cent of the world's land is more than 48 hours of ground-based travel from the nearest city. What's more, many areas considered remote and inaccessible are not as far from civilisation as you might think. In the Amazon, for example, extensive river networks and an increasing number of roads mean that only 20 per cent of the land is more than two days from a city - around the same proportion as Canada's Quebec province.

    Here's some more amazing Science to keep you going:

    1. There are 62,000 miles of blood vessels in the human body - laid end to end they would circle the earth 2.5 times

    2. At over 2000 kilometers long The Great Barrier Reef is the largest living structure on Earth

    3. The risk of being struck by a falling meteorite for a human is one occurrence every 9,300 years

    4. A thimbleful of a neutron star would weigh over 100 million tons

    5. A typical hurricane produces the energy equivalent to 8,000 one megaton bombs

    6. Blood sucking hookworms inhabit 700 million people worldwide

    7. The highest speed ever achieved on a bicycle is 166.94 mph by Fred Rompelberg

    8. We can produce laser light a million times brighter than sunshine

    9. 65% of those with autism are left handed

    10. The combined length of the roots of a Finnish pine tree is over 30 miles

    I will dig some more out ASAP!!

    Here is an interesting one. The reason a lot of people don't like the sound of nails on a blackboard is due to the frequency of the 'squeak'. It is very close to the frequency of the call that a monkey gives when it is in danger. If you are to believe we are evolved from primates it's a bit of a 'hangover' in our genetic makeup which instils a sense of fear in us. Of course, we don't feel it as fear so it just makes us cringe with discomfort.

    I think it's about 10hz

    I always do a cut on that frequency in tracks. it's the nastier end of the hi-hats sort of.

    our upper frequency response dies out as we get older. you may remember they invented an anti-chav thing that sent out a higher end tone that only kids can hear.

    Here's another does of Science facts to keep you on your toes.

    1. The oceans contain enough salt to cover all the continents to a depth of nearly 500 feet

    2. The interstellar gas cloud Sagittarius B contains a billion, billion, billion liters of alcohol

    3. Polar Bears can run at 25 miles an hour and jump over 6 feet in the air

    4. 60-65 million years ago dolphins and humans shared a common ancestor

    5.Polar Bears are nearly undetectable by infrared cameras, due to their transparent fur

    6. The average person accidentally eats 430 bugs each year of their life

    7. A single rye plant can spread up to 400 miles of roots underground

    8. The temperature on the surface of Mercury exceeds 430 degrees C during the day, and, at night, plummets to minus 180 degrees centigrade

    9. The evaporation from a large oak or beech tree is from ten to twenty-five gallons in twenty-four hours

    10. Butterflies taste with their hind feet and their taste sensation works on touch - this allows them to determine whether a leaf is edible

    I think you should have looked into it a little more!!



    # Sunquist, Fiona, "The colorful world of black white.black and white animals", International Wildlife, vol. 26 (3), p. 12, May, 1996.

    "In 1995, British scientists discovered that polar bear hairs block infra-red radiation and seem to suck in ultraviolet light which is used to heat their bodies. Possible applications include better lasers for eye surgery, more efficient solar panels covered with polar bear fur, and military camouflage undetectable by infra-red cameras."

    # "What color are polar bears?", Reuters News Service, August 19, 1986.

    "Two scientists from Northeastern University in Boston [Grojean and Kowalski] inadvertently have discovered that the thick, shaggy coats of polar bears are capable of incredibly sophisticated and efficient solar energy conversion, changing light that hits the fur to heat that warms the body...[W]hen [Lavigne and Oritsland] used ultraviolet equipment, which registers short-wave, invisible rays at the end of the light spectrum, the bears stood out dramatically, indicating an abundance of ultraviolet light on the bear's fur...Grojean says that a single hair of white polar bear fur, viewed under a microscope, is actually transparent. The clear, smooth-surfaced hair has an opaque, hollow, rough-surfaced core, called the medulla, that scatters light hitting the fur and somehow conducts 95 percent of the ultraviolet light down to the polar bear's black skin, where it is converted into heat."

    I was going to look for some references regarding the above. Now there are a few articles discussing the concept but nothing I can find that 100% supports the above fact.

    Here is an artical that I have just read.

    I think you should read it more carefully...

    I've enboldened the key words that give it away....

    enboldened! I love it! it's like that word on the Simpsons "enbiggened".


    Nice to see Ben back even if it is only for rebuttal purposes.


    There is a universe of difference between internet interpretation of science and facts. Real science finds it very hard to deal in absolutes at all.


    The clues are in there.


    Real science only please!
