Modular design: New insights into protein factories in human mitochondria

Phys.org 

The "power plants" of living cells, the mitochondria, probably evolved through endosymbiosis: A bacterium migrated into a primordial cell and eventually developed into an organelle that provides the cell with energy, among other things. Mitochondria produce some of the proteins they need themselves—with the help of special protein factories called mitoribosomes, which consist of RNA and proteins.

Influenza viruses can use a second entry pathway to infect cells, study shows

Phys.org 

Most influenza viruses enter human or animal cells through specific pathways on the cells' surface. Researchers at the University of Zurich have now discovered that certain human flu viruses and avian flu viruses can also use a second entry pathway, a protein complex of the immune system, to infect cells. This ability helps the viruses infect different species—and potentially jump between animals and humans.

But this slimy secretion exists in more places than just your nose and piles of dirty tissues—it also lines and helps protect the lungs, stomach, intestines and eyes.
