"Scientists Develop Adorable VR Goggles for Mice, Unlocking New Insights in Brain Science"

Scientists from Northwestern University have developed VR goggles, called iMRSIV, for laboratory mice to simulate their natural environment and study their behavior. The compact goggles provide an immersive 3D picture, allowing the mice to experience being hunted by a bird or other aerial threats. The researchers found that the goggle-wearing mice showed similar brain activity to free animals and performed better in tasks. The inexpensive and less complicated setup of the goggles could open the door to further research and provide insights into how the human brain reacts to repeated VR exposure.

"Wild microbiota in mice sparks powerful allergic immune responses, challenging hygiene hypothesis"

A study conducted by researchers from Karolinska Institutet challenges the hygiene hypothesis, which suggests that microbial exposure reduces the risk of developing allergies. The study compared the allergic immune response in "dirty" wildling mice, which have high infectious exposures from birth, to that of clean laboratory mice. Contrary to expectations, the researchers found that the wildling mice had robust signs of pathological inflammation and allergic responses when exposed to allergens. The findings suggest that the relationship between microbial exposure and allergies is more complex than previously thought and that general and broad exposures to microbes may not have the clear beneficial effects that were assumed.
