Hugging via the Internet possible??
Now hugging via the Internet is possible all thanks to a suit created by students and researchers at NUS (National University of Singapore).This device allows one to feel "hugged" by a family member or friend even if one is in overseas.
stomatic cell
People research stem cells because it can self-renew indefinitely and generate all the cell types of the organ,and has the potential to regenerate whole organs from a mere few cells .
It possess two properties:able go through numerous cycles of cell division while maintaining the undifferentiated state and generate progeny of several distinct cell types.However scientist think that this is not an essential property but due to the ability of adult stem cells to be being able to be harvested from the patient.Also this method is not controversial as it does not require the destruction of an embryo , and are not restricted to certain lineages.
Hence adult stem therapies require a stem cell source of the specific lineage needed and harvesting a certain of it.Thus this method has successfully treated leukemia and related bone or blood cancers through bone marrow transplants.
I feel that we need to have an adventurous mind as before who found out that stomatic cells could be used for these , many thought it was useless and did not bother investigating its properties , hence we need to have an adventurous mind to try out new things and you might stumble on something amazing.

HOPES for term 4
I hope to score a A1 for my EOY as if I get an A1 my MSG would be better.And to achieve this I will do more , read more and revise more as I want to get an A1 for he EOY as this is a very crucial exam and I hope to do well in it, and ace it
Term 3 reflection
During this term I work harder then term 2 and changed the way I revised science and got better results.However I will practice more on science as tireduce careless mistakes and hopefully point out which area I am weak in and improve on it.
I also hope that we can watch more videos as videos will usually be more interesting and I will learn more and it is more enjoyable as compared to a lecture.

Term 3 test reflection
I achived my target as set in term 2 and got a B3 for this term's test ,a major imrovement from C6 to B3 , which means that my new revision method worked and I will contiue to use this and improve on it.However it was the same old mistakes like careless mistakes such as spelling mistakes andlack of content knowledge.Also I hope that more examples of compunds/elements can be give to us as I was caught off guard when a question was set on examples.And I will continue to work hard and hopefully score better in term 4.
Term 3 lesson
I thought again that the topic of cells would be a breeze and again like the last term I was again confused with the new addition of cell parts and I am rather confused.However I think that I would be clearer by the end of the Term.I also knew more cell parts like in a animal cell, there were ribosomes, and also vacuoles were in them.Also I learnt that muscles can be divided in to 3 major groups voluntary, smooth and cardiac.And all these were not taught in primary school.
HOPES for term 3
My main target for Term 3 would me pullig up my grade.As a C6 would mean that my MSG would be rather high.Hence I have set a target for myself of acheiving at least a B3 for Term 3.And I will work doubly hard to achieve that as I felt hat I did not prepare well enough for the test , and my method of revision was flawed.Hence pulling up y science grade from C6 to at least a B3 would be my main target for Term 3.
