Oldest Oil Paintings found in Cave (national Geographic link added)


On the sixth of February of two-thousand six a mural made with oil paints was found in one of the famed Bamian Caves in Afghanistan and evidence of a oil-based binder that would have dried paint and help it adhere to the rocky surface it was painted on. With the murals were the remains of two giant destroyed Buddhas, and the mural was predated to be at least one-hundred years. Researchers made the discovery when trying to conduct a chemical analysis for preservation and restoration of Bamian. Which I think is all very cool.

An "Elite" Immune System can prevent AIDS(discover jan 2009)

Now another one I thought near impossible there is a way that you can be immune to AIDS. The people who can are only able to because they're immune system is powerful enough that it can withstand the full power of HIVs. These people have certain immune cells that stop the replication of the HIV. Joel Blankson an assistant at John Hopkins University says that because of these immune cells a vaccine for AIDs should be possible.

Is that a dead mouse your cloning?(discover jan 2009)


Japanese researchers were able to extract brain cell nuclei from two dead mice that were frozen for up to 16 years into mouse egg cells who's nuclei had been removed. The result was the mouse egg cells grew into fertile adult mice. This I thought wouldn't be possible but, apparently I was wrong and ice doesn't screw up brain cells. Now some people might think that we could now resurrect the ice age creatures that are in permafrost but it would be much harder and they could only do it to very very very close relatives to that creature.

Do the bubbles in champagne get you drunk faster?(science illustrated jan/feb 2009)


Champagne has been proven that people get drunk faster then non-carbonated wines with similar Alcoholic content. This was proven by Physicians at the University of Surry in England who did in experiment with 12 people who were told to drink and results were that the ones who drank carbonated champagne blood-alcohol rose a lot faster then those who drank the flat champagne. Why this is is still unknown but the guess is that the carbonation makes the stomach empty into the small intestine quicker, which would speed up intoxication.

Do ostrichs really stick there heads in the ground?(Science illustrated jan/feb 2009)


This article didn't surprise me at all. Ostriches DO NOT stick they're head in the ground when they are startled. But this myth came from what they do when they won't flee which is lie down on the ground with there head on the dirt, the reason behind this is there head is the same color as the dirt so predators won't see them.

Are jellyfish drinkable? (science illustrated jan/feb 2009)


This article was about if jellyfish could quench your thirst.In the article it said that it would not quench your thirst for a handful of reasons which are that the jellyfish have the tentacles that will sting you which if I'm correct is actually poison would be incredibly hard to remove and if you did do that the water in the jelly that makes ups 96% of it is just as salty as the water its in for buoyancy. But, according to research from the University of Washington if u took a jellyfish from water with a certain salinity into other water with a different amount of salinity after a while its body salinity will change so if you could remove the tentacles you may be able to slightly quench your thirst.

Is it possible to make artificial spider silk (science illustrated jan/feb 2009)


For this article I learned how difficult it is to make spider silk which I never thought of because well you know who does enough to research it. This article was about the production of artificial spider silk which is apparently incredibly hard to recreate. The reason the silk is so hard to recreate is because of the second step that is involved.The two steps that are put in to it are:1. manufacture the proteins spider silk glands use to make the silk and 2. and find a way to form the proteins into superfine threads. But despite how hard this is to do the Technical University of Munich in Germany tried to solve that by mixed the proteins with potassium phosphate like spiders then lowering the PH level of the proteins then finally applying pressure through tiny holes but that's only close to a spiders silk, they are able to make silk a fraction of in inch.
