Results from a new clinical trial suggest that a group of brain regions known as the “salience network” is activated after a drug is taken intravenously, but not when that same drug is taken orally. When drugs enter the brain quickly, such as through injection or smoking, they are more addictive than when they enter the brain more slowly, such as when they are taken orally. However, the brain circuits underlying these differences are not well understood. This study offers new information that helps explain what may be causing this difference.

The Centers for Disease Control and Prevention (CDC) is conducting a new pilot on samples it is collecting as part of its Traveler-based Genomic Surveillance (TGS) program that will provide early detection of flu, RSV, and select other respiratory viruses, in addition to SARS-CoV-2.

The World Health Organization (WHO) 2023 Global tuberculosis (TB) report underscores a significant worldwide recovery in the scale-up of TB diagnosis and treatment services in 2022. It shows an encouraging trend starting to reverse the detrimental effects of COVID- 19 disruptions on TB services.

Nearly 1 in 3 deaths from non-melanoma skin cancer is caused by working under the sun, according to joint estimates by the World Health Organization (WHO) and the International Labour Organization (ILO). The research released in Environment International finds that outdoor workers carry a large and increasing burden of non-melanoma skin cancer and calls for action to prevent this serious workplace hazard and the loss of workers’ lives it causes.
