Not all of the naturally occurring elements were discovered here on Earth. Helium was discovered by examining sunlight, and that same technique is now teaching us about the composition of distant galaxies.

MSG, or monosodium glutamate, got a bad wrap in the 1960s when people started complaining of “Chinese Restaurant Syndrome,” but that bad reputation was fueled more by xenophobia than science. Turns out, it’s just delicious.

No 1 – The Larch

Another Phase was over. Shaun Newton fell into his seat. He knew that this would have to go on. But for how Long nobody knew. The Situation with the prostate of the Usovai’i was cleared – somehow. The danger was still imminant. And there were still two departments to be evacuated. Newton was worried, because the scans indicated that the HIGH HAND changed their strategy. What were they up to?

He decided to take a nap and then carry on with his studies. He was in Need for fresh ideas.

Shaun Newton was tired. Here we go again, he thought. It was not yet over. Same procedure as last time. Coordination. Communication. Plans. But this time it was different. Two hours ago the Long range scans picked up signals. The High Hand was on the move. And the last two departments were just waiting for their evacuation. When everything was ready to safe the Science Department, the armies of the High Hand were aproaching their System. I always thought it was a bad idea to scatter the departments all around the place, Newton complained in his mind.

“Calling Science Department, do you read?”, he yelled into the comlink.

“Yes, we hear you”, the answer came right away. “This is Commander Aisha McClure. The enemy is approaching fast. What’s our time schedule?”

“No time schedule. We will be awaiting you on your Arrival. You may proceed as you wish. May the Flying Spaghetti Monster be with you!”

“Okay. Evacuation is starting now. Hope to see you soon!”

Shaun hoped that too.
