Key Highlights
•
A new gene therapy using a virus to deliver artificial microRNAs successfully silenced a specific human retrovirus protein linked to ALS in mice, slowing neuron loss and improving motor function. This provides a promising new therapeutic strategy for a subset of ALS patients where this viral protein plays a role.

A large study of patients with a rare inherited neuropathy found that harmful changes in a single copy of the SLC12A6 gene can cause Charcot-Marie-Tooth disease, a finding that expands the genetic causes doctors should consider for patients with these symptoms. This means genetic testing for this specific gene should be included for anyone suspected of having an inherited neuropathy, not just for severe recessive forms.

A review of research on driving and dementia found that family caregivers play a central but burdensome role in assessing driving safety, making decisions about when to stop, and managing the emotional fallout of that transition. This highlights the need for future support programs and research to explicitly include and address the unique challenges faced by these caregivers.

A study in macaque monkeys found that pupil dynamics are linked to recognition memory tasks, providing a potential physiological window into cognitive processes. This research helps build a bridge between observable physical responses and the internal mechanisms of memory, which could inform future studies on cognition and neurological health.

A new analysis proposes using “shooting-free days” as a simple, four-tiered metric to track gun violence in major US cities, moving beyond just counting incidents. This approach aims to provide public health officials and communities with a more nuanced and actionable measure of safety and the impact of violence prevention efforts.
