[In a small trial, an experimental medicine was 100 per cent effective at ridding the parasite that causes sleeping sickness from the bodies of people with an early to intermediate infection](https://www.newscientist.com/article/2349078-drug-clears-sleeping-sickness-parasite-from-the-body-in-clinical-trial/) https://images.newscientist.com/wp-content/uploads/2022/11/29225145/SEI_135659245.jpg ## Mauna Loa eruption interrupts key record of atmospheric CO2:

[The Mauna Loa Observatory has kept a nearly uninterrupted record of atmospheric carbon dioxide for more than 60 years, but a volcanic eruption has cut off power](https://www.newscientist.com/article/2349130-mauna-loa-eruption-interrupts-key-record-of-atmospheric-co2/) https://images.newscientist.com/wp-content/uploads/2022/11/29092910/SEI_135511239.jpg ## 'Unselfish' genes that make plants cooperate could boost crop yields:

[A simple breeding experiment can identify genetic variants that make plants grow well without impeding their neighbours, improving overall yields](https://www.newscientist.com/article/2348894-unselfish-genes-that-make-plants-cooperate-could-boost-crop-yields/) https://images.newscientist.com/wp-content/uploads/2022/11/28182742/SEI_135517144.jpg ## Bats and death metal singers use the same throat structure to growl:

[Daubenton’s bats use false vocal folds in their throat to produce a lower frequency grunt for communication – the same structure that lets death metal singers growl](https://www.newscientist.com/article/2348901-bats-and-death-metal-singers-use-the-same-throat-structure-to-growl/) https://images.newscientist.com/wp-content/uploads/2022/11/24110108/SEI_134850381.jpg ## Gliding sensors inspired by floating seeds will biodegrade after use:

[A biodegradable glider based on the seeds of the Javan cucumber, which float for long distances, could be used to monitor the environment without leaving polluting e-waste](https://www.newscientist.com/article/2348531-gliding-sensors-inspired-by-floating-seeds-will-biodegrade-after-use/) https://images.newscientist.com/wp-content/uploads/2022/11/29140551/SEI_135597261.jpg ## Boarding school rules on phones and bedtimes help teens get more sleep:

[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:
