A fatal mix-up: How certain gut bacteria drive multiple sclerosis

If gut bacteria are too similar to the protective layer of nerves, they can misdirect the immune system and cause it to attack its own nervous system. This mechanism can accelerate the progression of multiple sclerosis, as researchers at the University of Basel have shown in trials with mice. However, their results also open up opportunities for treatments that make use of the microbiome.

AI-engineered nasal spray antiviral platform developed to block flu and COVID-19

Respiratory viruses that have diverse strains and mutate rapidly, such as influenza and COVID-19, are difficult to block perfectly with vaccines alone. To solve this problem, KAIST’s research team has successfully developed an intranasal antiviral platform using AI technology to overcome the existing limitations of interferon-lambda treatments—namely, being weak against heat and disappearing quickly from the nasal mucosa.

Scientists develop mini human heart organoid that mimics atrial fibrillation

Though an estimated 60 million people around the world have atrial fibrillation, or A-fib, a type of irregular and often fast heartbeat, it’s been at least 30 years since any new treatments have been developed. This is because researchers haven’t had accurate models of the human heart to study. Thanks to new developments from Michigan State University scientists, that is no longer the case.
