Newly discovered trigger of Parkinson's upends common beliefs
A new study challenges a common belief in what triggers Parkinson's disease. Degeneration of dopaminergic neurons is widely accepted as the first event that leads to Parkinson's. But the new study suggests that a dysfunction in the neuron's synapses leads to deficits in dopamine and precedes the neurodegeneration. The findings open a new avenue for therapies in which drugs target neuron synapses before neurons degenerate.
Brilliant galaxies of early universe

Astronomers authored a paper confirming very bright galaxies in the early universe, while also disproving the identification of what would have been the most distant galaxy ever found.
