2:25 PM | In breve: la cascata dei barioni
In maniera semplice si può parlare di meccanica quantistica nel momento in cui si descrivono le proprietà delle particelle utilizzando i numeri interi. Fatti quei primi passi all'inizio del XX secolo, come fisici abbiamo descritto le particelle utilizzando i così detti numeri quantici in grande abbondanza: la loro scoperta era sempre legata alla scoperta di nuovi decadimenti che non potevano essere altrimenti spiegati senza violare la conservazione di un qualche numero […]

1:08 PM | As A Bird - It's No Turkey
Mr. Carlson and Herb Tarlek had to deal with the aftermath of bombing Cincinnati with live turkeys. The line about turkeys being able to fly is one of the most famous in TV history. But he should have at least questioned whether they could fly, there are more than 50 species of flightless bird alive as we speak.In a famous 1978 episode of the TV sitcom, WKRP In Cincinnati, station manager Arthur Carlson releases turkeys from a helicopter to a waiting crowd below as part of a holiday publicity […]

8:20 AM | Serotonin - melatonin (and the in-betweeners) linked to autism
The paper by Pagan and colleagues [1] (open-access) looking at "serotonin, melatonin and the intermediate N-acetylserotonin (NAS) in a large cohort of patients with ASD [autism spectrum disorder] and their relatives" set the old grey-pink matter into action recently. Not only because I have some real interest in the starting material for these compounds - the aromatic amino acid known as tryptophan - but because this research group included some quite important analysis of the […]
