Parkinson's Disease Patient‐Specific Striatum Organoids Show Hallmarks of Increased Inflammation

open access: yesMovement Disorders, EarlyView.
Abstract Background Dopaminergic neurons from the substantia nigra pars compacta project their axons into the dorsal striatum, forming the nigrostriatal pathway. In Parkinson's disease (PD), dopaminergic terminals degenerate in the striatum, leading to dopamine depletion, which in turn causes alterations in the basal ganglia circuits that are essential

Contrasting effects of temperature across trophic levels in geothermally warmed soil food webs

open access: yesOikos, EarlyView.
Global warming is altering the structure and dynamics of ecological communities, with significant consequences for soil food webs. Rising temperatures are expected to accelerate metabolic rates in organisms, potentially altering species interactions, and the structure and energetics of food webs.

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.
