- Scientists studied a common mouse virus in labs.
- The virus caused brain damage like Parkinson's disease.
- Researchers used animals to watch movement problems.
- They made a model without toxic chemicals.
- Infected animals became slower and less steady walking.
- Tests showed movement problems over time.
- The results are similar to human Parkinson's.
- Scientists will study the model and compare methods.
- The work may help find early signs.
- Support came from national research funding.

Navigation brain cells in retrosplenial cortex preserved across evolution
Researchers found two special neuron types in the retrosplenial cortex that help navigation. These cells are conserved between mice and rats, linked to spatial disorientation in Alzheimer’s, and are now being studied in humans.
Brainstem and spinal cord help control hand movements
A UC Riverside-led study published in the Proceedings of the National Academy of Sciences found that voluntary hand signals travel through the brainstem and top spinal segments as well as directly from the cortex. Mapping this pathway could guide new stroke therapies.
Milk glands in many mammals have receptors for H5N1
A study found that milk gland tissue from pigs, sheep, goats, beef cattle, alpacas and humans contains sialic acid receptors that can let H5N1 attach to cells. Researchers warn of surveillance and concerns about raw milk from mammals.
