Glycylation essential to keep sperm swimming in a straight line, shows study
One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are antenna-like structures that protrude from most of the cells in our body, contain many microtubules. An example of flagell is the sperm tail, which is essential for male fertility and thus for sexual reproduction.
The flagellum has to beat in a very precise and coordinated manner to allow progressive swimming of the sperm. Failure to do so can lead to male infertility. Researchers at the Institut Curie in Paris, the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden, the center of advanced european studies and research (caesar) in Bonn together with the University of Bonn, the Institut Cochin in Paris and the Human Technopole in Milan now show that one particular enzymatic modific
2021. január 8. 12:16 Both the Court of Justice of the European Union and the European Court of Human Rights have been progressively turned into constitutional courts. However, these judicial bodies are under the influence of a limited number of private funds and NGOs, including George Soros’s – says prof. Cliquennois who has been interviewed with respect to his newest book concerning this topic.
Gaëtan Cliquennois works as permanent researcher for the
French National Centre for Scientific Research at the
University of Nantes and deputy director at
Law and Social Change. His current research is focusing on the way the European human rights justice systemis caputred by private interests. He has published several articles insocio-legal and legal journals such as the
A few decades ago, some Senegalese men openly identified themselves as not male or female, but as an alternative gender - the “Góor-jigéen” or “men-women”. Senegalese society accepted them, and they moved about freely in the streets of Dakar and other towns, dressed as women.
Today, in those very same streets, men seen as behaving effeminately in any way are often harassed or attacked. Nowadays ‘Góor-jigéen’ has become a pejorative term targeting gay men.
Do any Senegalese still remember the time when this didn’t happen? Why did things change?
In this episode, we investigate the colonial roots of homophobia in Senegal. To do this, we travel back in time to when Dakar was known as the “gay capital” of West Africa.

Neanderthal s 41,000-year-old skeleton all set to resolve the long-standing mystery why the Stone Age hominins intentionally buried their dead.
The origin of funerary practices has important implications for the emergence of so-called modern cognitive capacities and behaviour.
