Virus carried by mice and given to humans in Yosemite park - 0 views

    I think this is scary for not getting more attention.

    I think that this is very dangerous and everyone should be aware of it.

Scientists reverse ageing in mammals and predict human trials within 10 years - 16 views

    "Using a new technique which takes adult cells back to their embryonic form, US researchers at the Salk Institute in California, showed it was possible to reverse ageing in mice, allowing the animals to not only look younger, but live for 30 per cent longer."

    I don't know how I feel about this, I think scientist are super smart people but there not using there knowledge to the best of there abilities... I personally find making animals live longer and possibly in the future creating a "medicine" or treatment to transform adult cells back to there embryonic form disturbing. It will probably cost a whole lot of money to. Its awesome how far they have come, but its weird when you mess with the life span of animals... it could also mess with natural selection.

    I think that it's amazing that science has come this far and they might be able to do this, but I don't think that we should reverse aging because we don't know the side effects on humans. I think they should just know they can do it but not use it because it could be harmful.

    "The breakthrough could also help people stay healthier for longer. The ageing population means that the risk of developing age-related diseases, such as dementia, cancer and heart disease also rises. But if the body could be kept younger for longer then it could prevent many deadly diseases for decades." It has a lot of pros and cons to this i think they shouldn't mess with the life span of make cells younger because that means there will be more people and the world could come over populated. But living longer would help a lot because you will learn more and be able to educate young people with better knowledge

    I think it's really good science has gotten so far that it is today because it helps us learn new things and better things and I think it will definitely keep advancing in the future.

    This could help millions of people on earth. If the body can stay younger for longer it decreases the chances of ageing related diseases.

Rats are being trained to detect explosives. - 18 views

    SWEET!! But I bet the people making bombs will make the trigger's more sensitive...but for now, the rats are a good alternative and cheaper too. What I am wondering is, how effective are rats at "letting" people know where there is a bomb. In this article/video, they placed a "test" bomb on the ground and the rat sniffed it out, but did they know only when the rat made it to the bomb and assume the rat had found their planted bomb and then rewarded the rat? Or did they wait for the rat to give them a "sign"?

    Rats are both smart and cute. I think it would be pretty cool if rats could detect bombs... They're the second smartest rodent in the world; they could make a hole in someones wall, and leave it alone for about an hour and then return to that hole, unlike mice who would get confused and make a different hole in the wall. Rats would be pretty easy to train to detect bombs, then give humans signs. I think this would be great.

    I like the idea of them using a smaller animal and one that is also intelligent because that is less money and less of a worry of putting larger animals in a more risky situation.

    If only all rats were trained to detect bombs. New York would be set...
  •  
    why not just let the rats run over the bombs to be able to blow up the bombs and it won't be a problem anymore.
  •  
    Because if the rats set off the bombs they would destroy whatever the bomb was put to destroy? Obviously that is a horrible idea.
