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.
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’.
Viruses, small infectious agents that replicate only inside the living cells of other organisms, have been around for billions of years. They can infect all types of life forms, from microorganisms, plants and animals to humans. It has been estimated that there are 10 to the power of 31 viruses on Earth, but humans don’t just live in a viral world, we are also part virus ourselves. Viruses actually comprise up to the 8% of the human genome and these so called endogenous retroviruses (ERVs) represent ancient viral infections that became integrated into the human genome.
The combination of drug misuse, reductions in antimicrobial research by the pharmaceutical industry, and the rapid evolution capabilities of microorganisms has resulted in pathogenic bacteria with stronger and stronger drug resistance. This is an issue that some fear if not handled correctly, could lead to the evolution of a “superbug” that is resistant to everything in our arsenal.
Zika virus has rapidly expanded during the last year in Brazil and currently the outbreaks are occurring in several countries and territories. While following preventive measures is extremely important to limit the spread, finding a reliable field diagnostic test is equally important. And it looks like we got one!
One of the hottest trends in life sciences research for the past few years has been the development of subfields of study focused on specific, complex networks within biological systems. These subfields are quite recognizable due to the common suffix ‘-ome’, and there is now an exciting and extensive list of “omes” starting with arguably the grandfather of them all, the genome.
Extraction of DNA before its amplification is an essential step for the measurement of any DNA target. It releases the DNA and removes substances inhibitory to PCR that are initially present in the matrix.
Metabolic studies investigating the mechanics of cancer cell proliferation have been critical to understanding resource allocation driving tumorigenesis. Generally, proliferating cells eschew efficient energy production in favour of metabolic pathways that generate the essential macromolecular building blocks necessary to grow in size and number, classically termed the Warburg effect.
There are approximately 140 000 species of higher fungi. Only 10% of mushroom-forming species are known, making them an enormous untapped pool of potentially useful substances.
