Book Description
This timely collection of original essays traces the migration of synthetic chemicals from the laboratory to the factory and then into the environment, bodies and communities. Turning our attention to the impact these chemicals have on our ecosystems, human health, social organization and political processes, the contributors break new ground by focusing on the production and distribution of these potentially hazardous agents themselves rather than just detailing their effects.

Book Description
If the solar system is regarded as a moving mass point system, then both the planet m and the sun M move around the solar system mass center O. According to the motion law of the mass point system and the centripetal force formula of the curve, it can be determined through theoretical analysis and mathematical derivation: (1) Kepler's law of planetary motion contradicts the motion rules of mass point systems. (2) The universal gravitational force F between planet m and sun M. K is the new gravitational constant. The force F' on the object m in the inertial frame S'. In the formula, V' is the velocity of the object m in the inertial frame S', and u is the velocity of the inertial frame S' in the cosmic space reference frame. In addition, the author designed three new optical experiments based on the light interference theory to verify whether the principle of constant speed of light conforms to objective facts. Experiment 1. Using the new front and rear hole laser interferometer for verification; Experiment 2. Verification of using long and short optical path Michelson interferometers; Experiment 3. Verification of using a double-hole interferometer.

Book Description
Imagining a future in which humans fundamentally reshape the natural world using nanotechnology, synthetic biology, de-extinction, and climate engineering. We have all heard that there are no longer any places left on Earth untouched by humans. The significance of this goes beyond statistics documenting melting glaciers and shrinking species counts. It signals a new geological epoch. In The Synthetic Age, Christopher Preston argues that what is most startling about this coming epoch is not only how much impact humans have had but, more important, how much deliberate shaping they will start to do. Emerging technologies promise to give us the power to take over some of Nature's most basic operations. It is not just that we are exiting the Holocene and entering the Anthropocene; it is that we are leaving behind the time in which planetary change is just the unintended consequence of unbridled industrialism. A world designed by engineers and technicians means the birth of the planet's first Synthetic Age. Preston describes a range of technologies that will reconfigure Earth's very metabolism: nanotechnologies that can restructure natural forms of matter; “molecular manufacturing” that offers unlimited repurposing; synthetic biology's potential to build, not just read, a genome; “biological mini-machines” that can outdesign evolution; the relocation and resurrection of species; and climate engineering attempts to manage solar radiation by synthesizing a volcanic haze, cool surface temperatures by increasing the brightness of clouds, and remove carbon from the atmosphere with artificial trees that capture carbon from the breeze. What does it mean when humans shift from being caretakers of the Earth to being shapers of it? And in whom should we trust to decide the contours of our synthetic future? These questions are too important to be left to the engineers.

Book Description
The revolutionary discovery of thousands of confirmed and candidate planets beyond the solar system brings forth the most fundamental question: How do planets and their host stars form and evolve? Protostars and Planets VI brings together more than 250 contributing authors at the forefront of their field, conveying the latest results in this research area and establishing a new foundation for advancing our understanding of stellar and planetary formation. Continuing the tradition of the Protostars and Planets series, this latest volume uniquely integrates the cross-disciplinary aspects of this broad field. Covering an extremely wide range of scales, from the formation of large clouds in our Milky Way galaxy down to small chondrules in our solar system, Protostars and Planets VI takes an encompassing view with the goal of not only highlighting what we know but, most importantly, emphasizing the frontiers of what we do not know. As a vehicle for propelling forward new discoveries on stars, planets, and their origins, this latest volume in the Space Science Series is an indispensable resource for both current scientists and new students in astronomy, astrophysics, planetary science, and the study of meteorites.

Book Description
In 2013, a Dutch scientist unveiled the world’s first laboratory-created hamburger. Since then, the idea of producing meat, not from live animals but from carefully cultured tissues, has spread like wildfire through the media. Meanwhile, cultured meat researchers race against population growth and climate change in an effort to make sustainable protein. Meat Planet explores the quest to generate meat in the lab—a substance sometimes called “cultured meat”—and asks what it means to imagine that this is the future of food. Neither an advocate nor a critic of cultured meat, Benjamin Aldes Wurgaft spent five years researching the phenomenon. In Meat Planet, he reveals how debates about lab-grown meat reach beyond debates about food, examining the links between appetite, growth, and capitalism. Could satiating the growing appetite for meat actually lead to our undoing? Are we simply using one technology to undo the damage caused by another? Like all problems in our food system, the meat problem is not merely a problem of production. It is intrinsically social and political, and it demands that we examine questions of justice and desirable modes of living in a shared and finite world. Benjamin Wurgaft tells a story that could utterly transform the way we think of animals, the way we relate to farmland, the way we use water, and the way we think about population and our fragile ecosystem’s capacity to sustain life. He argues that even if cultured meat does not “succeed,” it functions—much like science fiction—as a crucial mirror that we can hold up to our contemporary fleshy dysfunctions.

Book Description
Their planet had been ravaged by years of warfare. All life, apart from the many male species on their planet, have been eradicated. It has become vital to journey throughout many galaxies to gather much needed wildlife, plant life, and compatible females to replenish their world. In their travels, they discover Earth and its massive abundance of life. They decide to visit Earth to add to their collections. The supreme commander’s personal bodyguard, Jodar, decides to help his friends with the gathering on Earth. During this visit, they happen to come across an earthling female. This earthling beauty awakens unexpected desires he never expected to experience for himself. Jodar decides that he can’t leave this particular female behind, and he arranges for her capture. He must take her back with him to his home planet to discover if she is indeed what he has envisioned. During their collections to amass desperately needed life, they also uncover one of their own instigating an intricate conspiracy that could tip the scale for their enemy to triumph. Will this earthling female be what Jodar desires? Will the uncovered betrayal from one of their own, irrevocably provide their adversary the ultimate conquest after decades of battle? Can Jodar find true love and prevent the complete demise of his planet in time?
