research shows that slectively reduce the amount of the polutants can reduce the climate change.
the traget can be acheived if we can clean up the dissel engines, the cookstoves in india and china etc.
china has announced its new regulation regarding the vehicles.

what would happen if we cut down the black-carbon aerosols..

cut down all sorts of pollutants is our target because these pollutants cause many people lost their lievs. but it needs to be carefully done

a study about the physical changes about the cancer cells. They travel in blood vessels so that the friction is less and they can travel faster. The sceientists are going to do more research abouth the Tumor cells which taken from patient's blood vessel.

The F sequence number exists in the sunflower and other flowers
the sunflower has been taken as an example
it is stimulated by hormone
scientists predict the F sequence number exists in the natural more than previously thought

T1
The spiraling shapes of sunflowers follow the feature of Fibonacci numbers. They are tight as much as they
can be to maximize ability to gather sunlight for plant.  The reason that spiraling shapes follow the feature
of Fibonacci is auxin hormone. Such patterns might be universal in natrue.  

T2
Compared to human who become dads in their 50s, a wild guppy, one kind of fish, can be a father long up to almost
8 months, 75 years in human term, after he dead.  A group of scientist conducted a experience to test.  Female
guppy contributes to this phenomenon, they can store her consort's sperm for month.  The arrangement benefits for both
female and male guppies

T3
Overall cutting the use of fuels has proved a challeng, but if selectively reducing the particulate pollution will be
possible and helpful to reduce the climate change.  


T4
Several papers are related to this topic.  Although the selectively reduction is conductable, it should be careful.
When clean up sulfates from power plants, diesel emissions should also be made sure to cut down as well in case
the plannet would warm up.  

T5
To study physical changes that contribute to the process
of spread of cancer cell throghout the body is diffcult
MIT team found that cancer cells with higher metastati potential are more
deformable than nonmetastatic cells, also, cancer cells also seem to traverse narrow channeels more
easily because they encounter less friion.  
A further study will be performed.
