Artificial sweeteners are very useful for people who do not tolerate sugar. We all need some sweetness in our lives to bring out the flavours of the tea or make coffee a little less bitter. Saccharin, aspartame and other common artificial sweeteners  are great alternatives to sugar. However, a new […]

Escherichia coli bacteria are constitutive members of the human gut microbiota. However, some strains produce a genotoxin called colibactin, which is implicated in the development of colorectal cancer. While it has been shown that colibactin leaves very specific changes in the DNA of host cells that can be detected in colorectal […]

Oxygen deficit, also called hypoxia, in the brain is actually an absolute state of emergency and can permanently damage nerve cells. Nevertheless, there is growing evidence that to a certain extent, hypoxia can also be an important signal for growth. Together with scientists from the University Hospitals of Copenhagen and […]

Competition among sperm cells is fierce – they all want to reach the egg cell first to fertilize it. A research team from Berlin now shows in mice that the ability of sperm to move progressively depends on the protein RAC1. Optimal amounts of active protein improve the competitiveness of […]
