Tanks and the future of war is what Murray Leinster speculates about in this story. Written in the 1920's he observed the terrible new inventions that were used in World War I to kill people, armored tanks and poisoned gas, and then tells us how war will be fought in the future. In this case the war will occur in 1932 and be between the US and the 'Yellow enemy'. It was published in the very first issue of Astounding Stories of Super Science, January 1930. It is science fiction in ...

Murray Leinster does not disappoint with this gem of a story. The dust is deadly. It is slowly drifting down over the North American continent. Not ordinary dust, this dust is highly radioactive and silently deadly. Only one person sees too clearly that the USA is doomed and everyone in it unless this horrible, silent, death brining 'dust' can be stopped. And he, Doctor David Murfree, the only person to see the danger, cannot get permission from his superior to take leave from his civil se...

You who have read "The Mad Planet" by Murray Leinster, will welcome the sequel to that story. The world, in a far distant future, is peopled with huge insects and titanic fungus growths. Life has been greatly altered, and tiny Man is now in the process of becoming acclimated to the change. We again meet our hero Burl, but this time a far greater danger menaces the human race. The huge insects are still in evidence, but the terror they inspire is as nothing compared to the deadly Red Dust. ...

They were broadcasts from nowhere--sinister emanations flooding in from space--smashing any receiver that picked them up. What defense could Earth devise against science such as this? In the far future of 1972, on a secret military installation, Staff Sergeant Bellews is an expert on the latest scientific discovery: a way for ordinary machines like vacuums and lawnmowers to gather experience in their jobs, becoming error free over time. Then the strange broadcasts began to blow up transmit...

Humans have expanded to myriads of worlds throughout the galaxies but they have found that the only way for colonies to be self sustaining, was to reproduce the total ecology of their home world; the original Earth. This meant bringing the entire ecosystem, the good, the bad and the ugly. Viruses as well as grass, goats as well as stink bugs and allowing the whole mixture to ultimately produce an inhabitable world for humans. But what happens when this system is not properly supervised? Mo...

Moklins are the friendliest aliens humans ever encountered. They LOVE humans, and want to imitate them in every way they can. And evolution on Moklin is very helpful in this regard. After 40 years on Moklin, the only humans on the planet enjoy the friendship of these helpful 'people'. There might be one little problem though. Just a tiny thing that will cause the humans to leave in a very big hurry. Not that it will do any good of course.

Lon and Cathy, deeply in love and new farmers on a far away world, found they owed their souls to the company. The greedy company had designed it that way; a one way trip to the only planet that could produce the extremely profitable 'Thanar' leaves. All equipment was designed to break and so dig them deeper into debt to the Company. Their crops were mortgaged for years ahead now. It had seemed like a wonderful opportunity at the time, but the nasty truth was that they were raising Thanar ...
