Punnett squares and hybrid crosses
AbstractThe rapid reception of Gregor Mendel's paper ‘Experiments on plant hybrids’ (1866) in the early decades of the twentieth century remains poorly understood. We will suggest that this...

Tenfold Way for Quadratic Lindbladians.
We uncover a topological classification applicable to open fermionic systems governed by a general class of Lindblad master equations. These "quadratic Lindbladians" can be captured by a non-Hermitian single-particle matrix...

Expression of a carotenoid‐modifying gene and evolution of red coloration in weaverbirds (Ploceidae)
Red carotenoid colours in birds are widely assumed to be sexually selected quality indicators, but this rests on a very incomplete understanding of genetic mechanisms and honesty-mediating costs. Recent progress was made by the...

Of elephants and errors
What is it to make an error in the identification of a named taxonomic group? In this article we argue that the conditions for being in error about the identity of taxonomic groups through their names have a history, and that...

Evolution of CYP2J19, a gene involved in colour vision and red coloration in birds
Background: Exaggerated signals, such as brilliant colours, are usually assumed to evolve through antagonistic coevolution between senders and receivers, but the underlying genetic mechanisms are rarely known. Here we explore a...

Alpha-Synuclein Expression in the Oligodendrocyte Lineage
In this study, we sought evidence for alpha-synuclein (ASYN) expression in oligodendrocytes, as a possible endogenous source of ASYN to explain its presence in glial inclusions found in multiple system atrophy (MSA) and...

Human Astrocytes Transfer Aggregated Alpha-Synuclein via Tunneling Nanotubes.
Many lines of evidence suggest that the Parkinson's disease (PD)-related protein α-synuclein (α-SYN) can propagate from cell to cell in a prion-like manner. However, the cellular mechanisms behind the spreading remain elusive....

Systemic inflammation alters the neuroinflammatory response

Background

Neuroinflammation following traumatic brain injury (TBI) has been shown to be associated with secondary injury development; however, how systemic inflammatory mediators affect this is not fully understood. The...
