In 2010 John Craig Venter and his colleagues reported a creation of the first bacterial cell containing a completely synthesized genome. It was a 1.08-mega-base pair Mycoplasma mycoides JCVI-syn1.0 genome and it became the very first citizen of synthetic biology.

Engineers from University of California have designed wireless sensors as small as a grain of sand which can be implanted in the body and are able to provide nerve, muscle and organ signals in real-time. They use ultrasound to power the sensors and read out their measurements.
One of the particularly interesting chemical properties that are giving us some insight into our organic world is chirality. Chirality is a geometric property of most biochemical molecules that makes them different than their mirror images, just like our left and right hand are.
The discovery of the structure of DNA is known as one of the greatest discoveries in human history. It changed our perspective on human life forever, nevertheless one part of this magnificent story was left untold.
There is a new era rising in molecular biology and it began with CRISPR technology (Clustered Regularly Interspaced Short Palindromic Repeats), which is a genetic modification tool based on bacterial immune system. Gene drives is another interesting mechanism to use for altering genes but in contrast with CRISPR/Cas system it can only function in sexually reproducing species, leaving viruses and bacteria out of the picture.
Every living being on Earth is a part of a giant network where different species depend on each other for survival. This natural system is very complex and built of many different networks where different species interact with each other.
Scientists are making discoveries that change the way we live. Have you ever asked yourself about the revolutionary discoveries that have made a huge impact on our scientific way of thinking and our everyday life?
For more than a year one third of the world has been highly concerned about the Zika virus outbreak and Splice has covered amazing achievements regarding Zika infection. These days it is one of the main newspaper topics because of the upcoming Rio de Janeiro Summer Olympics in Brazil, the country where most of the cases of Zika infection were reported.
This is no novel idea, but after 17 years of a spirited debated, pharmaceutical companies are finally taking note. It was Dr. Mary Hendrix and her team out of the University of Iowa Cancer center in Iowa City who first reported in 1999 that human melanoma tumor cells were capable of forming perfusable vessel-like networks through a process called vasculogenic mimicry (VM).
A growing global epidemic of obesity and its related health complications such as type 2 diabetes is the reason why scientists are focusing on finding genes that increase the risk of developing obesity in the last decade. A breakthrough was finally made with discovery of the gene for ‘leanness’.
