Is Old Age Memory Decline Reversible?

well this information is great because if there cells stop reprodusing then they shoudent have there drivers licence because for example in stanstead there was a old ladie and she was driving on the rong side of the rode. that should show that they should not have there drivers licence. they sould not give them class to help there brain they should just live there lifes.

900 jobs affected as Dell closes Edmonton call centre

Dell Inc. announced Thursday that it is closing its Edmonton call centre, a move that will affect more than 900 employees...

When i read this article..i didnt really like it because i feel really bad for the people that just joined the company,they're only gonna be there for another ew months and its gonne shut down.

they say its the second time in a week they close down a computer company in canada.
i dont really think they should shut it down. Because they're are people working there that just got their job there.instead of shutting it down in may i think they should shut it down in a year instead if they want to do that.

I DONT THINK THEY SHOUT SHUT IT DOWN!

Smog Can Make People Sick, Even Indoors

This article that I read is about the smock in the cities and that this smock affect you in a lot of ways ,also indoors .

They found that outdoor air pollution, ozone, is associated with symptoms of lower-respiratory and upper-respiratory stress that occur in buildings to workers,"

Sick building syndrome is a term used to describe a broad range of ailments, including dry eye, congestion, difficulty breathing, fatigue and headaches that strike workers inside office buildings but disappear when they leave the premises. This studies shoes that the smock is really bad for your body and the problem is that this is almost in every part of the world .

i think that this research in indoors smog really helps the community because it hurts everyone and we really need to take care of our world our people and also we have to take care of us with this smog that we are doing we can get worst diseases.

i really like this article it also shows you that the smok is not also affecting peapole aut side also in buildings an inm your oun home , we should research more abaut this to know more stuff and try to reapear the damage.

virtual video games educational

VIRTUAL VIDEO GAME EDUCATIONAL? NASA SAYS SO.

When I read this article I agreed completely with NASA’s proposal to make a MMO that simulates how different scientific and mathematic problems work. But of course there are people who will try to abuse and take advantage of this. And of course this will be better than just reading a book or getting taught by a teacher. It will also help with as it says in the article building teams, solving problems and cleaning and handling equipment. Because the reality is that virtual games are the next big thing. In say 10 years time, maybe less the big game system on the market will be a virtual head set. The Wii is an example of this, just imagine a system that actually reads and responds to your actions. I a few years people will say “hey you wanna come over and play my new system it’s virtual”. But I think that it could be a new revolution in technology and the military is already using it so why shouldn’t NASA. Yes the military uses a steel circle that rotates and they give the soldier a helmet and a fake gun, they power it up and he is in a virtual world with virtual enemies and allies. So all in all this is an amazing thing and it will be on the market in the next ten years

more activity= slower aging.... being lazy=getting older faster!

recently, specialists discovered, a big cause of premature death and fast aging.
they experimented with blood samples of some 2,400 twins after making experiments and proving them they got to the conclusion that the ones who exercised the most (an average of 199 minutes weekly) had in average a decade biologically younger than the "lazy ones"(which did 16 minutes or less a week).
The scientists speculate that stress, inflammation and oxidative stress (cell damage caused by oxygen exposure) may be responsible for aging faster in people that dont do exercise. Exercise is among the factors found to help alleviate stress (oviously helping aging). Previous research has linked regular workouts to lower rates of cardiovascular disease, type 2 diabetes, cancer, high blood pressure, obesity and osteoporosis.
The researchers note that their findings support U.S. guidelines calling for individuals to exercise moderately for 30 minutes at least five days a week. "Our results. . . show that adults who partake in regular physical activity are biologically younger than sedentary individuals," they say. "This conclusion provides a powerful message that could be used by clinicians to promote the potential anti-aging effect of regular exercise."

my opinion:
I think this is very important and true because usually people that dont do exercise are more weak and get more diseases that people who do exercise. i think everyone should find time to do some exercise a day or maybe only resting the weekends because it helps getting rid of the stress, the fast aging,the diseases and after getting used to the sport it gets really fun and entretaining!! i think this article is very interesting and important and i agree that exersice is very important in everybodies life!

Mercury, As Never Seen Before

Mercury, As Never Seen Before

The article is about the Nasa's Messenger going to see mercury from a closer view, the trip was made on January 14.

This was really impresive, because not a lot of trips to the space go to "visit" Mercury. They were really, really close to the planet (that is the closest to the sun) and they were able to see the crater, and even though there was an expedition to this planet a long time ago, the sun iluminated another part of the planet, so when they went the last time they took pictures but were not able so see as good as this time, because of the light they could see different features from the planet that they didn't know before, they saw that the texture was different, they were able so see more about this planet.

They also saw that Caloris basin that is a crater in Mercury is one of the biggest from all the solar system. Other thing they saw is that in the atmosphere of Mercury that is really thin there is sodium, that is also in the Earth.

Other thing that the expedition did was the topographic measurements of this planet.

I think that is really interesting that people do this kind of expeditions, to know more about the other planets that are in the same solar system as our planet, because for me it's really interesting getting to know how all the planets are different and how they can have some similarities, and we just can know this if expeditions like this one are done, so I really like that they went there, and that they researched more about this planet, that not everyone know about because I think people talk more about planets like Mars, thinking if there is life there, or that water was found there, but how can we know about the other planets if there are no expeditions to research them, and I know it's difficult because of a lot of things, like just going out of our planet, and also because of the positions of the planets, that Mercury is the closer than any other planet to the sun so this makes it more difficult, but I really like all the research and pictures that was done.

Satellite may flail towards earth

I have always been interested about space, and was interested to read this article. I have read in many books that space junk is becoming a serious problem... I'd rather have junk in the middle of the universe than having it crash down on earth. It is actually very often that a satellite falls out of orbit and plunges towards earth but most of them burn up in the atmosphere. The debris that makes it through the atmosphere usually lands in a remote area and cause little or no harm. I thought that I knew a lot about space, but only through this article i learnt that the biggest satellite to fall to earth was named "Skylab" and was 78 tons. 78 tons is 70760.4097 kilograms and a heavyweight sumo wrestler only weighs 150kg +. I wonder why i have never heard of this before. It is probably because it happened in 1972 but still it is really interesting and i wish i knew about it earlier. What amazes me is that they already know about this incident and it is due to fall to earth in late February or early March. That is quite a long way away. My one last thought about this is, I hope it does not hit Stanstead Quebec.
