When we wake from the dream-laden phase of sleep, the brain boots up step by step. The first brain regions to rouse are those associated with executive function and decision-making, located at the front of the head. A wave of wakefulness then spreads to the back, ending with an area associated with vision. This precise understanding of how the brain transitions from slumber to alertness could help to manage sleep inertia - the grogginess that many people feel when hitting the snooze button.

Surgeons have developed two low-cost techniques to revive the hearts of people who wish to donate their organs after they die. These methods have only been tested on a small number of people, but they avoid ethical issues sometimes associated with current transplantation techniques.

The number of patients waiting for a lifesaving organ transplant in the UK has increased to a record high while there has been a sharp drop in donors.

Cellular memory refers to the ability of cells to encode, store, and retrieve information, which could significantly impact how we understand organ transplantation.
