Gut Bacteria Could Alter Parkinson's Treatment Efficacy
Patients with Parkinson’s disease are treated with levodopa, which is converted into dopamine, a neurotransmitter in the brain. In a new study, researchers show that gut bacteria can metabolize levodopa into dopamine. As dopamine cannot cross the blood-brain barrier, this makes the medication less effective – even in the presence of inhibitors that should prevent the conversion of levodopa.

Hand-knitted Molecules
Researchers have succeeded in producing molecules between two microscopically small, movable gold tips – in a sense as a "hand-knitted" unique specimen. The properties of the molecules can be monitored in real time while they are being produced.

It's a Knockout: Mouse miRNA Pair Provides Cancer Insight
A team at Tokyo Medical and Dental University has revealed the molecule to cancer development, showing that its absence leads to dysregulation of the cell cycle, albeit with differing cancer-related outcomes.

The Surprising Role of the Cerebellum in Reward and Social Behaviors
A new study in rodents has shown that the brain’s cerebellum—known to play a role in motor coordination—also helps control the brain’s reward circuitry. Researchers found a direct neural connection from the cerebellum to the ventral tegmental area (VTA) of the brain, which is an area long known to been involved in reward processing and encoding.

Targeting Tiny "Pocket" to Treat Stroke and Seizure
The ideal drug is one that only affects the exact cells and neurons it is designed to treat, without unwanted side effects. This concept is especially important when treating the delicate and complex human brain. Now, scientists have revealed a mechanism that could lead to this kind of long-sought specificity for treatments of strokes and seizures.
