Why does coffee keep us awake? What actually happens in the brain after a cup goes down? Many people find that after drinking coffee for a long time, its alerting effect is not what it used to be, and they may even feel sleepier the more they drink.

On August 15, the World Health Organization declared that the outbreak of a rapidly spreading mpox variant in Africa constitutes a "public health emergency of international concern," the highest-level global epidemic alert under the International Health Regulations. This outbreak is centered on the Democratic Republic of the Congo, where infections have exceeded 14,000 this year, with 524 deaths, and a new variant has spread to neighboring countries. Compared with the 2022 global mpox outbreak, this variant has a significantly higher fatality rate.
