Viruses

Viruses That Can Help Regulate Human Immune System

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. 

Antibiotics

New Synthesis Technique Leads to Over 300 Candidate Antibiotics

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-3D

Fast and Affordable Paper-based Test for Detection of Zika Virus in the Field

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!

Gut Microbes May Be Changing Our Minds

At the last year’s annual meeting of the Society for Neuroscience scientists presented a very interesting research topic about our gut microbiome. They have revealed that in some way gut bacteria influence the way how the brain work.  An important question arose from the mental health pont-of-view: Can we treat mental and neurological diseases by tinkering with our gut microbiome?

Metabolic Mojo of Cancer Cell Proliferation

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.
