By using new methods, we can heal, clean, produce new things – and also learn significantly more about life while developing these new methods.
Top 15 Biotechnology News In 2018
1. Engineered Bacteria against kidney disease
When oxalates accumulate in kidneys and urine, it can lead to severe renal disease and other complications. In order to help our own cells to digest oxalate, bacteria with genes that code for enzymes that can transform oxalate was developed. These bacteria They replace human enzymes and help the body to digest oxalates, thus preventing hyperoxaluria and kidney disease development. Reference :

3. DNA as a drug carrier
Modern nanotechnology manipulates various pre-existing molecules and allows novel applications. For instance, it was possible to construct DNA – based nanostructures that acted as drug carriers. These carriers were successfully used for delivery of favorite anticancer agents such as Doxorubicin and GpG nucleotides . Drugs “taking a ride ” on such carriers can are absorbed by the target cells more quickly and are also less toxic. Reference :

9. Do not waste food: give it to bacteria instead!
One should just put them into a bioreactor that contains mixed bacterial cultures and uses additional processes such as gasification and syngas fermentation. The potential output is extremely varied: from traditional bacteria-derived products such as ethanol or methane to biochemicals and bioplastics. Sustainable, zero- waste and zero- pollution industry is not just a vision anymore: it can very well become a profitable reality. Reference :

14. Speeding up the heart growth stem cells
This is a great thing both for heart specialists and researchers, as it is a way to understand how the heart tissue develops and reacts to the environment. The main drawback of such culture was the slow development of the cells of this type. Immature cells were not suitable for many kinds of research. Now it is possible to create conditions in which heart cells mature quickly, approximately over a month, and express most of the genes typical for adult heart cells. The researchers hope to use the new model line for studying heart pathologies such as cardiac hypertrophy. Reference :
