- The drug solriamfetol is the most effective treatment for excessive daytime sleepiness (EDS) for people with obstructive sleep apnea (OSA). 15 to 30 per cent of people in North America have a diagnosis of OSA and the prevalence could be much higher as many others are undiagnosed. https://brighterworld.mcmaster.ca/articles/mcmaster-researchers-find-best-treatment-for-excessive-daytime-sleepiness/ 62 comments science

- Scientists have developed an inhaled form of COVID vaccine. It can provide broad, long-lasting protection against the original strain of SARS-CoV-2 and variants of concern. Research reveals significant benefits of vaccines being delivered into the respiratory tract, rather than by injection. https://brighterworld.mcmaster.ca/articles/researchers-confirm-newly-developed-inhaled-vaccine-delivers-broad-protection-against-sars-cov-2-variants-of-concern/ 2890 comments science
- Researchers engineer cells to destroy malignant tumor cells. The modified "natural killer" cells can differentiate between cancer cells and healthy cells that are often intermingled in and around tumors, destroying only the targeted cells. https://brighterworld.mcmaster.ca/articles/natural-killers-researchers-engineer-cells-that-attack-and-destroy-malignant-tumor-cells-but-leave-the-rest-alone/ 4 comments science

- Processed meat and health. Following participants for almost a decade, scientists found consumption of 150 grams or more of processed meat a week was associated with a 46 per cent higher risk of cardiovascular disease and a 51 per cent higher risk of death than those who ate no processed meat. https://brighterworld.mcmaster.ca/articles/processed-meat-linked-to-cardiovascular-disease-and-death/ 429 comments science

- Study: Evolution drives autism and other conditions to occur much more frequently in boys and men. The human genome has evolved to favor the inheritance of very different characteristics in males and females, which in turn makes men more vulnerable to a host of physical and mental health conditions. https://brighterworld.mcmaster.ca/articles/evolution-drives-autism-and-other-conditions-to-occur-much-more-frequently-in-boys-and-men-genetic-researchers-say/ 37 comments science
