Entombed microbes in salt crystal believed to be 30,000 years old

Researchers from the university of hawaii  studied  salt crystal taken from a sediment core taken from death valley in california.
The salt crystals contained small quanties of liquid and the researchers grew live colonies from the samples.
The liquid was dated at between 22-34 thousand years ago.

The structure of these salt crystal indicates they were formed in a hypersaline lake,
As they has not been a permanent lake in Death valley for at least 10,000 years,this means recrystallisation properbly hasn't taken place,suggesting that the microbes are as old as they appear.

the same crystals also containe  dead cells from a salt-lake algae called Dunaliella algae,which have high levels of glycerol.
It has been calculated that a single dunaliella cell contains enough glycerol to meet a microbe needs for 12 million years.

Sweetener may cause health problems

A study has proved that  fructose,a corn-derived sweetener,used in thousands of food and drink products  can damage human metabolism and cause obesity.

Fructose can cause dangerous growth of fat cells around the liver,heart and digestive organs.
Fructose arrives intact in the liver causing abnormal reactions,including disrupting the mechanisms that tell the body to store or burn fat.

The study involved 16 volunteers on a strictly controlled diet,with high levels of fructose,whereas another group of volunteers were on same diet,but with glucose instead,the later volunteers did not get same problems.

Rinderpest faces total wipeout

World health bodies believe that within the next 18 months,rinderpest will hopefully be a thing of the past,joining smallpox  which was declared extinct in 1977.

Hopefully they will able to declare it eradicated.

Mega-flood created mediterrean sea about 5.3 million years ago

About 5.6 million tears ago,the mediterean sea almost disappeared through evaporation,when it become disconnected to the atlantic,due to uplift of the straits of gibraltar and a drop in sea levels around that time.

Tectonic activity around 5.3 millions years ago lowered the  gibraltar strait.

Researchers have concluded that the flood started with a trickle of water  over a rock barrier over thousands of years,which deepened the channel until the rock barrier failed,filling the mediterrean basin in less than two years.

This water create a 200 kilometre long gorge which is 250 metres deep.
