This reference work lists all organisms which produce antibiotics in alphabetical order. It also covers the production of antibiotics from many new strains of known organisms, as these produce new antibiotics as well as amounts of known compounds.
The boundaries of space exploration are being pushed back constantly, but the realm of the partially understood and the totally unknown is as great as ever. Among other things this book deals with astronomical instruments and their application, recent discoveries in the solar system, stellar evolution, the exploding starts, the galaxies, quasars, pulsars, the possibilities of extraterrestrial life and relativity.
To the crew of the Exploratory Ship Canopus, outward bound on the first intergalactic voyage to the flaring suns of mighty Andromeda, the evil whisperings that spilled out from the nebula into deep space came as a warning. This was something far beyond their previous experience. Nor were they the only ones to come under the malignant influence of the alien intelligence. In the empty, murmuring void, virtually half-way between the two galaxies of stars, a solitary sun streaked away from Andromeda, dragging its lonely, ammonia-laden planet with it. And it was here that the explorers first gained their glimpse of the black horror that lay straddled across the intergalactic darkness. Something that had being. Something that existed where it seemed impossible that anything could. It fell on Klau-Telph, the only non-Terran on board the Canopus, to finally track down and destroy the inhuman monster that threatened to drive the inhabitants of a trillion planets over the red edge of madness. Not until it was done did he find that the hidden reason behind the insidious whisperings was not what it seemed. In fact, it was something that even he, with his strange double mind, had never thought possible...
Earth was threatened with attach from the huge space-fleets of the Hundred Suns of Andromeda - an attack that the Terran Fleet could not hope to defeat. Only one chance remained to prevent Earth's destruction, and that was the chance that a skilled and experienced saboteur might just have time strike his blow before the enemy could launch the attack. It was Captain Blair whose mission this became, and it was his ace-saboteur who raced against death in planet after planet, as the zero-hour approached when Earth would face the attacking fleets of DARK ANDROMEDA.
The logical outcome of the space race, and the preliminary step towards the Moo, was the manned satellite, the Big Wheel moving in a stable orbit about the Earth, integrating the data necessary for a landing on the Moon, and eventually acting as a fuelling station for the Lunar rockets. After several failures, the station is ready, but even there, danger exists, unseen, unheard, invisible and terrible. Forced to exist in the belt of cosmic radiation surrounding the planet, men die within weeks from aplastic anemia. Seeking a solution to the problem, Doctor Paul Russell is sent up to the satellite and here learns of the two men fro the previous crew who vanished without a trace after spotting an unidentified spaceship in orbit further out from Earth than themselves.
They came out of the void, from Venus, only to find there was no answer to their radio signals. Earth seemed dead. And on the Moon, Man's greatest achievement, the Lunar Military Base was a mass of rubble and blasted wreckage. Here, the crew of the Stellar Polaris, led by Commander John Forrest, discovered one sole survivor. He was mad! To their questions he could only answer that the children had destroyed the armed might of the Military Base. When they finally reached Earth, they found that what he had said was true. The children had taken over control of the world. But then, these were no ordinary children - and their little weapons were almost enough to overthrow the armed superiority of the Stellar Polaris herself!
The world that Man has known for close on twenty thousand years had been overthrown in a holocaust of atomic fire and annihilation. The immense and complex system of civilisation had been utterly destroyed almost overnight and only a scant handful of true humans remained. Stretched out between the rivers of radioactive fire, the cities were growing wildernesses of shattered stone and brick, splintered glass and silent streets. But here and there in quiet places sheltered from the deadly rains, men waited for the fires to subside and hoped to rebuilt something a little like the civilisation which had existed before. This is the stirring and sometimes terrible story of the supreme struggle for survival, when the continued existence of the human race on Earth is uncertain after such a tremendous catastrophe, and when all life is menaced by the wandering bands of mutants, creatures spawned and tainted by the deadly radiation.
They came out of the star-strewn wilderness around Sol, these alien creatures. And their object was the vicious, total destruction of the Federation of Worlds. Earth was one of the last pf the planets to be attacked and here they were opposed by the Earth Council: six men who held the destinies of a hundred billion people in their hands. But in the end, there remained only one man out of the six to fight. Velga Dorne, Earth Councillor and Member of the Triumvirate of Worlds. And he himself was a hunted man. Death and terrible destruction followed him across the wastes of space in the search for the crazy, nightmare planet that had spawned these creatures. Fear and terror were his only companions. Until he reached the nameless planet of a still more insignificant sun and learned that there were others to join him in the struggle against the black, inhuman monsters. These were the Hheroni, scientists whose achievements had progressed along a slightly different path of research to humanity. And Astraea, the girl who went with him on the suicidal mission to where the Aliens originated: on a world that no one in their wildest dreams had thought possible to exist, one which even science said was impossible.
Planet Earth was finished, its surface seared by nuclear heat, its great cities obliterated, its billions of inhabitants dying or dead. Only a few pockets of survivors remained. For all but a few it was only a matter of time. Then into the poisoned atmosphere of Earth there flashed a mysterious craft from somewhere deep in space. It landed, a small number of Earth people were taken aboard, then the craft disappeared into the great void. During the dark millennium which followed a strange experiment was conducted. When it was complete, another space craft took off for Earth...
With the discovery of the hyperdrive, mankind at last possessed the means of going out to the stars. Four expeditions had already gone by the fine the fifth starship left Pluto for Vega. Carrying its complement of scientists and military personnel, they arrived at the solar system of Vega to find one planet sufficiently like Earth to allow them to land. Here, they discovered mystery. The ruins of great cities built on the shattered remains of still earlier fortresses, showing that some great race of conquerors had passed that way sometime in the past thirty thousand years. No life now remained on this planet and speeding to the next sun, they found a civilisation which possessed powers so utterly strange to them that one native almost succeeded in destroying them and taking over the ship. And still the mystery remained, for the legends of the planet spoke of a race of gods who had come down from the stars twenty thousand years before. It was not until they reached the planet of a red giant sun that they ran into a race of creatures so fantastically alien that there was no defence against them, and they learned the real identity of the race which had conquered the stars millennia before...
All the known planets had been conquered and colonized. Pluto was the last - as far as man could go into space. Beyond the frozen planet lay an immeasurable gulf of light years which no man could cross in a single lifetime. But one man kept trying to find the answer.
They came out of the great abyss which lay around the Earth, from the planet of a star so distant that it could not be seen with the naked eye. Their purpose was survival and the conquest of Earth. They were alien and possessed a mysterious force which lay at the very origin of human comprehension; the ability to enter into a man's mind, to make him think the thoughts they chose, to make him hear and see and feel the things they wanted. Against such a force there seemed no defence; for who could say that the man or woman by his side was not motivated by one of these creatures? Who could say that his own thoughts and senses belonged to him and not to some 'thing' seated in some alien way inside his brain?
The Nebular Variables focuses on the nebular variables and their characteristics. Discussions are organized by type of nebular variable, namely, RW Aurigae stars, T Orionis stars, T Tauri stars, and peculiar nebular objects. Topics range from light variations of the stars to their spectroscopic and physical characteristics, spatial distribution, interaction with nebulosity, and evolutionary features. This volume is divided into four sections and consists of 25 chapters, the first of which provides general information on nebular variables, including their stellar associations and their classification into three distinct groups: RW Aurigae, T Orionis and T Tauri variables. These three groups of nebular variables are examined in more detail in the chapters that follow in terms of their light variations, spatial distribution, interaction with nebulosity, and spectroscopic, physical, and evolutionary characteristics. Visual and photoelectric light curves, mass loss determined spectroscopically, luminosities, and stellar radii are considered. The book also explores the possibility that some of the nebulae associated with certain nebular variables have evolved from a protoplanetary disc of material consisting of both gas and solid matter. Peculiar nebular variables such as the long period variable R Aquarii, Herbig-Haro objects, symbiotic variables, and infrared stars are analyzed as well. This book is written primarily for students and teachers of astronomy.
Earth had been destroyed, but man had built his colonies on Mars and Venus and the far-flung moons of Jupiter and Saturn. Mutation and forced breeding had changed these people so they were no longer human. Clyde Lester, the last man on Earth, had a special problem. From somewhere in space there originated strange radio signals which could only come from beyond the orbit of Pluto, the outermost planet.
Ernest Oliver, a former lecturer in mythology, moves to the remote Northumberland coast to finish his book. However, he is quickly drawn into a series of eerie events surrounding an abandoned house known as the Carter place. When his uncle, the village doctor, shares his own terrifying encounters and the unexplained disappearances of locals, Ernest's academic curiosity turns into a struggle for survival. As they investigate the house, they face an ancient, malevolent force—one that might be older than humanity itself, lurking in the dust-covered ruins.
Ellen Grossen thought she could handle the solitude of the isolated mansion, even with her sickly husband Andrew's bizarre tales about spiders and souls. But when Andrew's lawyer, Brander, warned her about staying alone, Ellen dismissed his concerns. As a storm raged outside, an eerie tension filled the house, and Ellen began to sense something watching her. The discovery of Andrew's obsession with spider cults and his belief in the transmigration of souls left Ellen teetering on the edge of fear and disbelief. Now, with Andrew's death, the spiders are closing in, and Ellen must confront a horrifying reality...
Over the long years, ships of the Interplanetary Confederation had scoured the empty wastes surrounding Sol, searching desperately for a sister planet; a companion for the isolated worlds of the Solar System. Of the ships that were sent out, many returned. But always the answer was the same. There were no planets! The worlds of Sol were alone in the Great Dark that swirled across the boundless heavens. It was not until Steve Rane and Nick Brodine, in the Exploratory Ship Vega, reached across the yawning gulf of light years to Sirius, that they found the strange planet that rotated in its complicated orbit around the twin sun. It was an event transcending all others. A discovery that plunged the planets of Sol into the greatest race of all time. For whoever controlled the alien planet, controlled the Solar System. And away from the watchful eye of the IPC it would be possible to build the greatest space armada in history and attack the Interplanetary Confederation without warning. To Steve Rane, the order came from Earth Central. Zero Point has been set for three months hence. The ship of Jupiter must not reach the new planet first.
Men had fought wars throughout history, but never such a war as the one which destroyed the cities of earth and turned vast areas into badlands, stretches of intense radioactivity where nothing could grow and no one could live. It also produced the deviates, mutants who had warped bodies and strange talents. But there were others who had still stranger talents, mental powers exceeding those of the mutants, and whose bodies did not bear the sign of the deviate. Their origin could not be traced to an atomic war; even they themselves had no idea whence they came. Forced to take part in the abortive war between the Eastern and Western Federations, one man and one man eventually escaped and discovered creatures similar to themselves. But to discover their origin they had to go back five thousand years; and the answer lay not on earth, but somewhere in the stars.
