How to print a brain - the initial steps

To understand the biological processes that take part within living organisms, and also as an alternative method to animal experimentation, researchers are trying to develop new models that mimic real tissues and organs, and that behave as the real ones. This field of research, tissue engineering, is a multidisciplinary field where medicine and engineering work together in order to replace, regenerate or improve a part or function of the body. However, first approaches in vitro (in the lab, outside the normal biological context of the cells), were performed in 2D (two dimension, into a plane). These configurations did not allow cells to behave properly, as they do not recognize the environment where they are placed, which is far from being similar (...)

A new code for a new life

Life on our planet is based on DNA. DNA is a big molecule present in all organisms, and it contains the instructions to build each of life's components. It is the biological way to store and spread information. It is the universal language of life on Earth. DNA's language is composed of four different letters called nucleic acids or bases: adenine (A), thymine (T), cytosine (C) and guanine (G). All together they form a sequence that can be read and translated by living cells into 20 different amino acids (the building blocks of proteins), which, in turn, can be assembled into functional and structural proteins. This is the basis of all the living things we know. Since the beginning of life on (...)
