NASA is being told to cancel 19 *active* missions to save $6B, which looks to be less than the ICE *hiring/retention* budget going forward. I need people to let that sentence sink into their bones for a minute.

How many insects can you see in this photo? Believe it or not, there are five. This termite alate fell victim to four perfectly camouflaged assassin bug nymphs (Reduvius tarsatus) Their bodies are covered with minute setae that trap grains of sand and various debris, making them virtually disappear.
