Galaxy Formation + Evolution

Formation of galaxy is still one of the most active research areas in astrophysics and this is also true for galaxy.Some ideas are still not widely accepted.Most accepted view today is that all structures we observe today was formed as a consequence of the growth of primary fluctuations.
Primary fluctuations causes gas to be attracted to areas of denser material,and star clusters and stars.
Consequence of this model is that the location of galaxies indicates areas of higher density of the early universe.Even the distribution of galaxies is closely related to the physics of the early universe.
This topic is really interesting and i really do want to know what there is in the galaxy.

Discovery of Brain's Natural Resistance to Drugs May Offer Clues to Treating Addiction

An injection of cocaion or any other type of drugs causes mice to stop the neurons that generate sensations of plesure.These cellular changes last for a week.Findings suggest this powerful reaction to the drug may be a protective anti-addiction response.Scientists theories that its possible to mimic this responses to treat this addiction to this drug and perhaps other bu t they need to research more and do more experiments.Scientists were amazed that one exposure to these drugs could promote a really strong response that lasts a week even after the drug leaves the body.They believe that this could be the brains immediate response to reverse simulation to these drugs.

So technically when the brain knows that drug entered the body the brain tries to fight it or defend its self.

But the scientists are still trying to understand better the brains response to drugs.Why?They're hoping to find a way to prevent it and tread addiction.Also they're doing this because a lot of people died because of drugs.In 2009 more than 37,000 people died because of drug abuse.

Scientists are researching cellular changes to the brain that occur while taking drugs.

Heres what happens after using drugs for a couple of years.

While i was living in Novi Sad at night sometimes even during the day drug dealers and drug addicts would try to get in.One day when my dad was coming back home from work he saw a syringe  and while he was getting into and out of the lift there was blood on the walls,floor,everywhere.

I think that this what scientist are doing is really important and good fro the society.Drugs don't make you feel good or better they just help you die quicker.

For all we know some of our friends even family could be addicted.We are not aware how much people are on drugs and we probably don't even know how much this project will help.
