The human body contains 10 times as many bacterial cells as it does human cells
Using bacterial DNA analysis, the scientists sampled bacteria found on healthy human skin at 20 different spots on the body
The nose is also where bacteria stay that often recolonize other parts of the body,
Oily parts of the skin, like next to the nose or behind the ear, are host to a whole different ecosystem of microorganisms
"Eczema is always inside the elbow. Psoriasis is on the outside of the elbow. Those human cells are the same."
Despite their proximity, the microbes that live inside the elbow and outside the elbow are quite different. Psoriasis and eczema don't appear to be caused by bacteria, but they could be a reaction, triggered by a change in the ecosystems of germs

These cells produce a constant stream of ghrelin whenever the stomach is empty. The ghrelin travels via the blood stream to the brain's appetite centre, an organ called the hypothalamus. As a result, the hypothalamus screams "You are hungry - find food."
But whenever the stomach wall is stretched - when the stomach is full - the cells stop producing ghrelin, and the hypothalamus responds accordingly, turning off the appetite signal. The longer the stomach remains full, the longer you feel satisfied and the less you are likely to eat.
In the battle to lose weight, hunger is the dieter's worst enemy. But research has revealed a simple aid to taming the appetite: soup
If you eat the food and drink the water, you will feel full for a couple of hours before hunger kicks in. But if you blend the food with the water - to make soup - you will stay hunger-free for much longer, and less likely to snack
When you eat the same meal as a soup, the whole mixture remains in the stomach, because the water and food are blended together. The scientists' scans confirm that the stomach stays fuller for longer,
The key to this low-tech weapon against hunger is a hormone called ghrelin

THE average loan size for first-home buyers has risen by $52,000 - or 23 per cent - in the past two years, raising fears that the much-publicised government incentives for young buyers are artificially inflating the market.
A report commissioned by Brandmanagement, a market research firm specialising in the finance sector, says the average size of loans being taken up by young home buyers is jumping by an "unsustainable" amount, The Australian reports.
Drawing on Australian Bureau of Statistics figures, the report has found the average size of the loans rose by $11,400 in the three months to February, after rising by $18,100 in the three months to November.
In total, the first-home buyer average loan size jumped by $52,000 to $280,600 in the two years to February.
The huge rise in the value of their individual loans in recent months has seen first-home buyers become an increasingly important part of the residential loan market.
The figures show that by February they comprised 26.9 per cent of that market: up from just 17.3 per cent in February 2008.
The actual number of first-home buyers also rose sharply in the year to February 2009: rising from just over 9000 to more than 14,400 in the year to February 2009.
The Federal Government's First Home Owner's Boost scheme - which provides up to $21,000 for new homes and $14,000 for established homes - is now being progressively phased out, and will cut out altogether after the end of this year.
Sydney couple David Halter and Kate Tulip, both 25, are among the thousands of first-home buyers who have entered the market - and taken on a sizeable mortgage - since the beginning of the year.
Last month they bought a two-bedroom apartment in Lindfield, on Sydney's north shore, and Mr Halter said the first-home buyers grant was a major factor in their decision to buy the flat.
But Brandmanagement's principal, Andrew Inwood, said the statistics - which indicate that property prices are rising in line with loan sizes - have raised questions about whether the government incentives were simply being used by consumers to buy into a bubble.
