[At one high school, students who boarded had a consistent lights-out time and no phone access in bed, with these students getting almost five hours of extra sleep a week compared with the students who only attended school during the day](https://www.newscientist.com/article/2349006-boarding-school-rules-on-phones-and-bedtimes-help-teens-get-more-sleep/) https://images.newscientist.com/wp-content/uploads/2022/11/29124201/SEI_1339847461.jpg ## Do we have 'immunity debt' and how could it affect our infection risk?:

[The covid-19 lockdowns undoubtedly saved many lives, but the prolonged restrictions also reduced our exposure and immunity to other infections, which could be set to spike in the UK this winter](https://www.newscientist.com/article/2348968-do-we-have-immunity-debt-and-how-could-it-affect-our-infection-risk/) https://images.newscientist.com/wp-content/uploads/2022/11/28154751/SEI_135493909.jpg ## Brain mapping in mice may explain why pain makes us lose our appetite:

[Researchers have identified different pathways that lower a mouse's desire to eat when it's in pain - and a similar brain circuit could also occur in humans](https://www.newscientist.com/article/2348855-brain-mapping-in-mice-may-explain-why-pain-makes-us-lose-our-appetite/) https://images.newscientist.com/wp-content/uploads/2022/11/28135431/SEI_135475790.jpg ## A rat without a Y chromosome could be a glimpse of our genetic future:
