Exploring the Cell, by Dr. Danielle Hamilton

Next in our weekly series of articles, Dr. Danielle Hamilton, a Research Scientist with the Centre for Chromosome Biology, writes about her work “Exploring the Cell” and how understanding how a cell repairs damage to its DNA may lead to the prevention and treatment of cancer.

Every living creature is made up of one or more cells, and humans are no exception. These microscopic structures are the building blocks of our bodies and each is programmed to perform a specific function. Cells of the same type are often found clustered together and communicate with each other to form the tissues and organs that make up a functioning organism.

Science in the Garden by Dr. Naomi Lavelle

This week, in the seventh of our series of articles, we have a real treat in store for our readers. The one and only Dr. How (aka Dr. Naomi Lavelle) has written a very special article for us about Science in the Garden, and has enlisted the help of two very capable junior scientists, Culann (aged 8) and Rohan (aged 4), who you will meet in the videos below!

I watched the ReelLIFE SCIENCE school video competition with great interest last year. What a wonderful way to get children excited and involved in Science. I was delighted to be asked to write an article this year in celebration of the launch of the 2014 competition. I think the topic of Science in the Garden is a great way to open children’s minds up to the science around them… literally right outside their door!

Exploring the Cell, by Dr. Jessica Hayes

In ‘Exploring the Cell‘, the sixth in our weekly series of articles by NUI Galway researchers, Dr. Jessica Hayes, Research Fellow within the Orthobiologics group in the Regenerative Medicine Institute (REMEDI), takes us on a journey inside the cell and tells us how stem cells are being used in medicine to encourage the body to repair itself.

Cells – the building blocks of the human body. Here we demonstrate how molecules form cells. Groups of cells in turn form tissue which combines with different tissues to form an organ such as the heart, stomach, brain etc. Several organs that function together form an organ system i.e. cardiovascular, respiratory, reproductive systems etc. (Image source: http://www.studyblue.com/notes/note/n/introduction-to-the-human-body-chapter-1/deck/282266)

The Latin phrase ‘Omnis cellula e cellula’ or, all cells come from cells, was made popular by the German pathologist Dr Rudolph Virchow, and it is this concept that forms the basis of regenerative medicine. But what are cells and why are they so important?
