Hello Everyone! Just a quick note here to let you all know that Astrochem Coffee for July of this year will be delayed just a bit due to summer holidays (the Dougs have collectively decided to take a vacation to Menorca for the next couple of weeks). This month's episode will come out mid-August, and then we'll back to regularly scheduled episode drops in early September. Hope everyone is enjoying their summer holidays as well.
