A Detailed Map of the Mouse Nose Is Rewriting How Scientists Think About Smell

Researchers have created a comprehensive map of mouse olfactory receptors, revealing that smell is organized far more precisely than previously believed.

Key Takeaways

Researchers mapped around 5.5 million neurons from more than 300 mice to chart olfactory receptor organization.
The study found smell receptors arranged in tight bands rather than randomly across the nasal cavity.

Mouse Study Links Nerve Growth Factor to Osteoarthritis-Like Changes

A new study highlighted by Medical Xpress reports that nerve growth factor alone caused osteoarthritis-like joint changes in healthy mice, pointing to a possible deeper role for the protein in joint disease.

Key Takeaways

Medical Xpress says NGF alone triggered osteoarthritis-like changes in healthy mice.
NGF is a neurotrophin tied to sensory nerves and the fight-or-flight response.

Mouse study suggests adolescence leaves the brain more vulnerable to stress

A study in mice suggests stressful experiences during adolescence can leave deeper, longer-lasting marks on the brain than similar stress in adulthood.

Key Takeaways

Researchers reported that stress during adolescence caused deeper and more lasting brain changes in mice than stress in adulthood.
The finding highlights adolescence as a distinct developmental window rather than a simple extension of adulthood.
