(RSS) (Proteom Res News) How does time blood spends on ice alter the proteome? At least some important proteins absolutely change!:  

I can't possibly spend the time on this new study that it deserves, but I really am going to think about it on my commute today. Or listen to the Halo Effect album I didn't know about until yesterday because that's how busy my 2025 has been. And maybe also think about this paper.
