Humback whales have been endangerd for along time, people have harshly killed them for many reasons one being their blubber. As threatend species they have made a surprisingly made a remakable comback in the West cost of Canada. In the north pacific they have doubled in the last two years the amount of whale s is 20,000.
Jackie Hildering is a whale studier in Boughton Archipelago off trhe northcost of Vancouver Island. She has been watching the whales and noticed that over the past years she has never seen so many whales, she has seen over 50 whales. She also said that she is very happy to see the whales come back so fast and in a big amount.
Jay Barlow, a scientist with the National Oceanic and Atmospheric Administration he has also been watching the whales and has seen the same thing as Jackie but he is questioning if the whales are going to last. He said they have manage to stay away from being hunted but know they have to deal with natural changes. Like the climate change that will change the temperature of the water that the whales may or may not be able to adapte to. Also with water changE that also affects the other animals so that could limite their food supplies.
For a long time people have been trying to protect the humpback whales and even though they have made a big comeback we just have to wait to see how long it last.
1) Do you think that the whales will stay for a long time or not?
2) Do you think the climate will have an affecte on the whales were it gets to the point whan they can no longer survive?

NATURAL DISASTERS!!!!!!
A natural disaster is the effect of a natural hazard, that effects the enviroment and leads to financial, enciromelntal, and human losses. There are alot of different types of disasters, like earthquakes, volcanoes, hurricanes, etc. The largest canadian disaster was in 1998
Natural disasters are stuff that fear is made of.We can prepare for them, but we cant prevent them, we can anticpate them, but we cant accurately predict them. Natural disasters let us know that the planet is in charge.
I think that natural disasters cant be stopped, but if they could they should be.... natural disasters do no good to anyone, they harm people, their homes, land and so much more. I think its great how people are taking the time in raising money fot the disasters!!
I have a couple questions that i have that would be interesting to know....
1. If you were a natural disaster what kind of disaster would you be and why?
2.What would you do if you were in a situation that you had to prepare, what would be the first thing you bring, and where would you go?

Champagne Bubbles Liberate Flavor Compounds
A team of Europeans finds that the bubbles in
sparkling wine drag compounds that active smell
receptors to the surface of the sparkling wine and
then shoot them upward where a taster can easly
encounter them.
The thing is, when the bubble burst the consentrate surface
active compounds are thrown several cm into the headspace,
where they can meet a taster notril's.
1-What do you think about this article?
I think this is not very important compared with others articles but
in this article you have to think about it because is not that easy, how
to know about this, you have to think.
2-how did the smell cames out the drink?

A brain-boosting video game
WHAT IS IT ABOUT?
Three Canadian researches scanned the brains of fifteen teenagers girls (12-15 years) who play Tetris (a video game where you need to organize blocks).
After three months, their grey-matter (wrinkly misture of brain cells and blood vessels reponsible for processing information in the brain) was thicker and some of it was on the top of the brain.
After discovering that, the researches scanned brains of 11 year olds who didn't play and compared them. Turns out the grey-matter of the 11 year old wasn't thicker, because they weren't playing.
The researches didn't know if it was a good thing and if it is a positive thing for the brain.
WHAT DO I THINK ABOUT IT?
I really thought this article was pretty cool and very unusual. What caught my attention the most was the fact that girls played and where "studied", not boys.
QUESTIONS
1)So, I would like to know what you think about the article.
2)Do you think that, in a way, it desenvolves your brain?
3)Do you think it is a good thing or a bad thing?

oil spills in the ocean
SUMMERY
I read an article today about oil spills and its effects. lots of oil spills are accruing around the world. lots of them are illegal dumpers. illegal dumpers are people who dump crude oil into the ocean because they do not want to spend money on decomposing their waste oil. But dumping oil in the ocean is illegal thats why they call them illegal dumpers.
THE EFFECTS OF OIL SPILLS
Oil spills have a big effect on the animals that live in the ocean. Like sea birds. when a sea bird gets oil on its body there is a very high chance of it dying. when it gets it on its feathers it trys to clean it off by eating it. once it gets into its body it becomes poisoned and will die. Another way is that it will get it in itss eyes and the bird will become blind. when its blind it is most likely going to be eaten because its not aware of its preditors.
THE LOCATIONS OF SOME OF THE WORLDS LARGEST OIL SPILLS
1983 the Persian gulf - 600,000 tons of oil spilled
1983 south Africa - 250,000 tons of oil spilled
1988 the Monongahela river - 3,800,000 tons of oil spilled
1993 off the Shetland island -26,000,000 tons of oil spilled
1996 off SW wales - 18,000,000 tons of oil spilled
2001 Galapagos island - 240,000 ton of oil spilled
WHAT I THOUGHT ABOUT THE ARTICLE
I personally thought that this article was very interesting. I never really thought about how much oil spills effect our oceans. I mean i saw commercials on TV where it shows birds covered in oil and people cleaning them off and where it shows a dead killer whale washed up on a beach covered in oil. I new that oil spills where bad but i never really payed any attention to it. This article made me realize how important it is to not dump oil in our oceans.
Navy Green: US.Navy Investigates Biofuels to Power Its Ships and Planes
Ships powered by algea and planes flying on weeds.?
This is a project the U.S navy hopes to bring to fruition in the near futur.
Summary
This week, the seagoing branch of the military purchased 40,000 gallons of jet fuel derived from camelina—a weedy relative of canola(this biofuel reduces carbon emissions by 80 percent compared with conventional kerosene)—and 20,055 gallons of algae-derived diesellike fuel for ships.
The three goals of this project are fuel security, something that is renewable, and
that they can produce and provide for themselves to reduce their reliance on foreign sources of oil. It also has to be cost-effective. Then, obviously, the environmental benefits that could potentially derive from that."
The Navy hopes to put the biofuels in active planes and ships in 2010 and 2011.As it stands, the Navy uses at least seven different types of petroleum-based fuel and burns nearly 35 million barrels per year.
The main problem this project has encountered so far is finding alternative fuels that will work in many different types of aircraft, ships, engines, boilers and turbines employed by the fighting force.They other thing is finding an alternative biofuel that does not compete in the food market such as ethanol which is derrived from corn.
I think this project is really cool because it consists on finding alternative fuels which are much better for our environment than our conventionnal fuels. The other thing is that theyre ussing fuels that wont have to compete in the food market like ethanol which is really good.
Questions
- In what other aspects of our every day life do you think these biofuels could be used in.?
- When thinking about these fuels how do you think they will be used in 100 years from now and for what purpose.?
- If this project were to succed and be fully deployed around the earth do you think ordinary fossil fuels will still be needed and why.?

Scientists are studying the strong and stretchy material in spiders, insects and even goats.
Summary
We have all seen spider webs – on the trails we walk on or in the corner of our bedrooms catching flies and other insects. Author Rachel Ehrenberg writes about the other known and possible uses of animal silk. The material insects use to spin webs or create cocoons is called silk.
Silk from insects like spider or silkworms is extremely strong and natural. Researchers are looking into ways to use natural silk for additional uses. Bulletproof vests and parachute cords are two possible ways. But the silk could also be used inside our body – to protect cells, like bone or nerve cells while they regrow and repair themselves.
Spider silk is so valuable that scientists are trying to find additional ways to produce it – like altering the DNA of a goad so that it produces silk proteins in it’s milk. I suppose that this would make it a lot easier to harvest than getting it from the spiders.
I think this is a really interesting topic – but I think I would be nervous to let them plant silk producing spider genes into my body no matter what the possible positives are!
Read the article and see what you think for yourself.

Discussion Questions:
- Can you think of additional ways that strong and stretchy fibers could be used to help us on the outside of our body?
- If the science was mastered – do you think you would use silk fibres to help your body from the inside? Say it could help repair a broken bone?

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!!!

erosion in paradise
Now I know this is a little off the topic of the requested summary but, in the Turks and Caicos there is major erosion and so I want to share it with you guys. In the TCI there was a house right on the beach. The guy who owend it was rich and arrogant if you ask me. Over the many years that house resided near the beach, erosion kicked in and soon his house was on a extremly unstable cliff. Of course it fell in the water and all the money but into it was gone...but this is one example of extreme erosion happening on my island. This will soon become a problem as we have no volcanoes like hawaii to repopultae the land once its gone. At my beach, a beach where there is only five people at any time, there was a project to replenish the sand that was washed away. Another rich and arrogant guy behind this (with a mean gardener). It was great... for a while, until it all turned to custard. Don't ask me how bvut when trying to make the beach better, the works made the rocks and sand unstable and super erosion started. Now it looks horrible. Good job I have a pool :)! Erosion is a powerful force of nature and I would like to learn how my beach was destroyed.
Coping With Shoreline Erosion in Sept-Iles
In
Investigating the Ocean
In BC Christine Erbe is an oceanographer. She is trying to find out if the noise from motor boat harms Sea lions and whales, it affects them seriously the way they find prey the way they communicate and detect predators. She says that it can even damage there ears and organs, that is not good. Her job? She is trying to find sea lions and whales all day and in the picture I think she does find animal’s everyday, but it is a very hard job to it cost a lot of money for her to do this but she also makes a lot of money doing it. The good thing? She gets to spend everyday or mostly everyday on the ocean looking for whales and sea lions that is really cool, but she is also helping them and helping the environment at the same time and about nature to. What do I think about this? I think this would be a really cool job to do it actually sounds awesome, I would love to look for whales and sea lions all day, I did the same thing like her up in taddosac we went whale watching and we so so many it was really cool.horrible hurricanes coming up!!!!!!!
This article is informing us about the climate changes and possible natural disasters!!!!
The U.S. National Weather Service Climate Prediction Center forecasts six to nine hurricanes —including as many as five major hurricanes with wind speeds above 111 miles (179 kilometers) per hour in this six-month season in the Atlantic, (which begins on Sunday and ends November 30).
Experts in different places say the same about the natural disasters coming up, they say that this will be a more active year than most for tropical cyclones in the Atlantic and Caribbean.
The total prediction calls for as many as 16 of this horrible storms!
Depending where one of this storms are born it can be called a hurricane, typhoon, tropical cyclone or a cyclonic storm. By any name, one of these storms can carry as much energy as 10,000 nuclear bombs—making them nature's most destructive meteorologic phenomenon.
Because climate change an the rise in global temperature, experts say that there will be tropical cyclones more often and more powerful in the future.
My opinion:
I think this is a very shocking article, in a way it is really scary to see all this big horrible things that are happening because of global warming, and climate change, I think it is really good that this types of article exist so that people can see and know everything that is happening, and that will happen! I think people should change because even if all this natural disasters are going to happen, and there is nothing to do about it, If we (humans) don’t change natural disasters like this ones are going to be worse and worse until we cant control them at all! I think is a very interesting article and people should read this types of articles more, to realize all this horrible things that are happening in the world, and realize that we need to do something now before it is too late!

Over 50 Percent Of Oceanic Shark Species Threatened With Extinction
"The first study to determine the global threat status of 21 species of wide-ranging oceanic pelagic sharks and rays reveals serious overfishing and recommends key steps that governments can take to safeguard populations. These findings and recommendations for action are published in the latest edition of Aquatic Conservation: Marine and Freshwater Ecosystems."
Scientists determined that 16 out of the 21 species of sharks that live in the oceans, get caught by fishers, and that they can get extinct really easily, because when they catch them, the catches are not regulated.
They are vulnerable to be over fished, because a lot of times they don't reach the age in which they are sexually mature and have offspring. So the population of sharks can go down easily.
"Fishery managers and regional, national and international officials have the opportunity and the obligation to halt and reverse the rate of loss of biodiversity and ensure sharks and rays are exploited sustainably." says lead author Nicholas Dulvy from the Centre for Environment.
"The current rate of biodiversity loss is ten to a hundred times greater than historic extinction rates, and as humans make increasing use of ocean resources it is possible that many more aquatic species, particularly sharks, are coming under threat," says Dulvy
So some of the solutions for this problem are to establish limits for catching them, so that the sharks can be controlled.
I really like everything about marine life, so I think that this is a problem that has to stop, because all fish and sharks are going to be extinct if this doesn't stop.
So if this doesn't stop soon, it can happen faster than anyone can think.
More other things consequences can happen because if sharks get extinct, they can stop the food chain, and then more problems will come on and on and on, so it is important that it stops.
And besides animals don't have the fault from anything, the fishers are the ones that are making mistakes sometimes not really knowing, so I think that authorities should really put an end to this.

Bloomberg Lays into Policymakers' "Political Science"
This article is about Mayor Michael Bloomberg of New york saying that pollution is growing and we must put a stop to it. He also discussed the fact that science is more important than politics. He was discussing this at the World Science Festival. He is stating that politicians have throughout history ignored sicentists waranings on many things such as the link between smoking and lung cancer. When polictics ignore science he says it is because of political science. he also believes that it is an important issue to reduce greenhouse gases.
My opinon is that we all have to start taking steps for a better future and a better life. It would be nice if politicians began listening to scientists about what is happening on our planet, after all they are the ones that do all the research and can help solve the problems.

Monkey's brain controls robot arm
In this article, the u.s.a scientific though that it could be possible to feed a monkey
with a robotic arm.
Scientists at the University of Pittsburgh and Carnegie Mellon University
implanted tiny electrodes into the primary motor cortex, the region of the
brain that sends electrical signals to other parts of the body to control movement.
After programming the arm to respond to certain brain activity,
the researchers were then able to train the monkeys to operate
the arm and have it reach for a treat, pick it up and bring it to their mouths.
They made the monkey learn haw to use it by first observing,
which activates his brain cells as if he were doing it.
University of Montreal researcher John Kalaska, who was not part of the research team, described in an accompanying news article the ease with which the monkeys adapted to and learned to control their robotic arms.
In the experiment the monkey learn by watching just like the scientific s thought it will be.
They say the research could lead to the development of prosthetics for people with spinal cord injuries and those with conditions such as Lou Gehrig's disease, or amyotrophic lateral sclerosis.
My opinion !!!
i think this experiment is really good because if this work they could help people that need it.
they should keep researching and doing more experiments like this , that could help people.
if it works it will be really cool and people could have more possibilities to live better.
