New mechanism involved in senescence modulates inflammation, response to immunotherapy

Scientists at The Wistar Institute discovered a novel pathway that enables detection of DNA in the cytoplasm and triggers inflammation and cellular senescence. This pathway may be modulated during senescence-inducing chemotherapy to affect cancer cell response to checkpoint inhibitors. Results were published online in Nature Communications.

What birdsong tells us about brain cells and learning

Most scientists who study the brain believe that memories are stored through networks of synapses, or connections that form between neurons. Learning takes place as neurons form new connections and strengthen or weaken existing ones, giving the brain its so-called synaptic plasticity. There is growing evidence, however, that the intrinsic, built-in properties of the cells themselves, not just the connections between them, also play a role in this process.
