Unveiling Bacterial Immune Mechanisms Against Temperate Phages

Like humans, bacteria can be attacked by viruses. In the case of bacteria, these viral attackers are referred to as bacteriophages, a term derived from the Greek word for bacteria-eaters, or simply “phages.”

Dendritic Spine Clusters Physically Link Memories Formed Close in Time

According to a recent study, the reason why memories from the same day seem connected while events from weeks apart feel separate is as follows: Human brains use dendrites, which are spiny extensions of neurons, rather than the cell bodies to physically connect memories that happen in close succession.
