After a heart attack, the heart signals to the brain to increase sleep to promote healing

A new study found that the heart sends signals to the brain to increase sleep after a heart attack, promoting healing and reducing inflammation. This communication between the heart and brain is mediated through the immune system and can lead to improved recovery and reduced risk of further cardiovascular events.

Study shows that Rett syndrome in females is not just less severe, but different

Researchers found that female mouse models of Rett syndrome have a mosaic-like distribution of cells expressing wild-type and mutant MeCP2 protein, leading to dysregulated genes. The study also discovered an unusual disease progression, with females having more dysregulated genes at the pre-symptomatic stage than later on.
