Monitoring Antarctic Ice Movement Is a Sticky Business
This article is about scientists discovering exactly how large pieces of ice like glaciers actually move they are called "sticky spots". What is a sticky spot? A sticky spot is when seismic pressure builds under the ice and when it becomes too stong the ground underneath the ice actually begins to move which causes the ice to move. The whole process is called a "stick and slip" movement. Does the ice moving have anything to do with global warming then? Scientists have been telling us for years that this ice is melting and we are all doomed and it's all because of global warming. This doesn't sound like global warming! This sounds like the earth shifting and shaking which causes movement of ice that eventually leads to or breaks off into the ocean. These chunks of ice aren't small, they are as big as some US states! Maybe that's why we are all in a panic? When these chunk lead into the ocean they will eventually melt raising sea levels. Then, I guess, we are doomed!
Impulsivity Linked to Cocaine Addiction
"Call it the chicken-and-egg debate of the addiction world: Cocaine addicts are known for being frenetic, but which came first, the behavior or the habit?"
New studies (made with rats) proved that is the behavior what makes somone addict.
Experts think that this might help later for solving problems with addictions.
Scientists study frug addcits when they already have an addiction, so it's hard to know if their behavior took led them more to the addiction.
"What they do know is that two traits--impulsiveness and thrill-seeking--tend to define most drug addicts. Although the behaviors are similar, scientists have been able to parse them in the lab: Highly impulsive rats jump the gun on simple tasks--pushing a button, for example, before they are signaled to do so; thrill-seeking rats, meanwhile, will rapidly explore any new environment--immediately sniffing various objects in a new cage, for example--whereas normal rats would wait until they felt comfortable in their surroundings. "
What this says, is that the behavior can change the results. For example, if the rat had an impulsive mood or temper, then they could be more likely to have an addiction.
Some other studies that the scientists did, was to put a kind of disspenser to the rats, they put it so they could take cocaine when ever they wanted too. The impulsive rats weren't fast to turn to the drug, but when they did they took it in small amounts.
"After 40 days of free access to cocaine, however, the impulsive rats were the ones who became the addicts. They were unable to stop taking cocaine even when it meant getting an electric shock, the team reports. The thrill seekers, meanwhile, had lost interest in the drug; apparently, the thrill was gone"
So this proves that the impulsive rats were the one who became the addicts, and it didn't matter for them if there were consecuences about keep taking them.
So this also shows that there is a connection between impulsive people and drug addcits, well, rat drug addicts at least.
A psychopharmacologist at the University of Bristol in the U.K. Marc Potenza, a psychiatrist at Yale University, believes that the research has important implications for treating drug dependence. "We might be able to identify individuals at early times in their lives that may be prone to developing addiction," he says.
I think this is something that will really help for predicting which kind of people would be more likely to have an addiction, and is a kind of prediction too, a way of prevention, if people know that being an impulsive person leads more to have an addiction, then all the poeple can be informed about this, and maybe parents, or friends from people that are impulsive can help them so know about the problem, it can really be a way of helping all this people to know if someone can become an addictict but also to help them to prevent it.
So every time, science is more amazing, because almost all of the blogs that I've done, are of things that I don't ever think about can be posible, not knowing how a person's mood can really affect a situation, so I really like knowing about this, becuase it's a way that you know more about facts that seem that doesn't matter but that at the end they really do.

oil spills and its effects!!
This article is informing us about what are oil spills and how they affect the enviorment the marine life and the consequences of them!
What is an oil spill, when do they happen?
An oil spill is when oil goes into the ocean because of different human activities, or natural disasters for example:
-when people make mistakes or are careless and cause an oil tanker to leak oil into the ocean.
-When countries are at war, one country may decide to dump gallons of oil into the other country’s oceans.
-people dump crude oil into the oceans because they do not want to spend money on decomposing their waste oil.
- natural disaster may cause a oil tanker to spill, and others!
What are the consequences of an oil spill?
Because of one single oil spill, millions of animals die, causing the enviorment, the food chains and the ecosystem break!!!
millions of birds die from oil spills if their feathers are covered in oil. The bird will then be poisoned because it will try to clean itself. Animals may die because they get hypothermia, causing their body temperature to be really low. They may die from really low body temperature. Oil may also cause the death of an animal by entering the animal’s lungs or liver. The animal will then be poisoned by the oil. Oil also can kill an animal by blinding it. The animal will not be able to see and be aware of their predators. If they are not aware of other animals, they may be eaten.
Scientists have discovered that after a simple oil spill, its extremly difficult for animals to recover and that ten years after the spill, animals are still affected by it!
Oil spills sometimes are the reasons of animals becoming endangered!!!!!!
My opinion:
I think that this artice is very important because when people hear about a oils spill, they usually think about a little bit of oil in the sea that killed some birds (thats what i thought an oil spill was), but this article actually tells you how it affects millions of animals, and the whole marine life! And after reading this article, you can see that only because we (humans) are too sellfish, or not consious, we end up killing millions of animals, and affecting the whole marine life! I think this article is very good, and really makes you think how this is impacting the enviorment and that we need to be carefull in what we do and how we do things because oil spills are not just something that will da,age for one day, and be perfect the next one, it impacts so much, and after years and years, the harm will still be there!!!! I think this was a very interesting article that more people should read , and become aware!!!
