¿Por qué el estómago no se digiere a sí mismo?
¿Cuánto se puede comer antes de “explotar”?
¿Puede matar el estreñimiento?
¿Mató a Elvis…?
Lleno de curiosidades y anécdotas, pasearemos entre laboratorios de pruebas de sabor de alimentos para mascotas, trasplantes fecales, o viajaremos a un estómago en vivo para observar qué ocurre allí con l. a. comida. De l. a. mano de Roach viajamos por el mundo para conocer asesinos, científicos locos, exorcistas (que han llegado a administrar agua bendita rectal) o terroristas…
Al igual que todos los libros de Roach, Glup trata no solo de cuerpos humanos, sinode seres humanos.
By Freeman Dyson
Readers of Freeman Dyson’s prior books, hectic the Universe, guns and wish, and countless in All instructions, have came upon for themselves what Dyson finds the following: that he was once a author lengthy earlier than he turned a extraordinary scientist.
The target of this new booklet, as Dyson says, is to open home windows, to enable the specialists contained in the temple of technology see out, and to permit the standard electorate outdoor see in.” during this method an immensely extensive diversity of principles, humans, modern background, and discoveries of many varieties cross in review.
Beginning with an editorial he did as a baby and finishing with fresh paintings, he is going from Eros, the god or younger ardour, to Gaia, the fertile life-giving mother-planet Earth. The pilgrimage is an efficient metaphor for the lifetime of a writer.
This publication is filled with discoveries. within the corporation of 1 of the main lucid minds of our time, one techniques nice males and difficulties significant to our universal life. regularly there's heat, kindness, excessive intelligence and humor.

Whether he's facing the issues of physics or politics, even if he's engrossed in astronomy or literature, even if he's focusing on an African village of house technology, Dyson’s view is often “infinite in all directions,” continually following the trail of variety, continuously conserving his eye at the ask yourself of our earth and the health and wellbeing and happiness of its population.
Edited and written by means of a global "who's who" of greater than a hundred authors, together with anesthesiologists, nurse anesthetists, bench scientists, a health care provider, and representatives of industry, this article offers a complete heritage of anesthesia, specific in its specialize in the folks and occasions that formed the strong point world wide, fairly in past times 70 years whilst anesthesia emerged from empiricism and constructed right into a science-based perform.
By Jerry A. Coyne
"Coyne's wisdom of evolutionary biology is prodigious, his deployment of it as masterful as his contact is light." -Richard Dawkins
within the present debate approximately creationism and clever layout, there's a component of the talk that's hardly mentioned-the facts. but the evidence of evolution by way of typical choice is massive, various, and luxurious. during this succinct and obtainable precis of the proof aiding the idea of average choice, Jerry A. Coyne dispels universal misunderstandings and fears approximately evolution and obviously confirms the clinical fact that helps this awesome means of switch. Weaving jointly the numerous threads of recent paintings in genetics, paleontology, geology, molecular biology, and anatomy that show the "indelible stamp" of the techniques first proposed through Darwin, Why Evolution Is True doesn't goal to end up creationism flawed. particularly, through the use of irrefutable proof, it units out to turn out evolution correct.
By Peter Dauvergne
The Shadows of Consumption offers a hard-hitting analysis: some of the earth's ecosystems and billions of its individuals are in danger from the implications of emerging intake. items starting from autos to hamburgers supply conveniences and pleasures; yet, as Peter Dauvergne makes transparent, worldwide political and financial methods displace the true charges of customer items into far away ecosystems, groups, and timelines, tipping into main issue humans and locations with out the facility to withstand. In The Shadows of Consumption, Peter Dauvergne maps the prices of intake that stay hidden within the shadows solid by way of globalized enterprises, exchange, and finance. Dauvergne lines the environmental results of 5 commodities: vehicles, gas, fridges, red meat, and harp seals. In those interesting histories we examine, for instance, that American officers missed warnings concerning the risks of lead in gas within the Twenties; why China is now a number one manufacturer of CFC-free fridges; and the way activists have been in a position to cease Canada's advertisement seal hunt within the Eighties (but are not able to take action now). Dauvergne's cutting edge research permits us to work out why such a lot of efforts to control the worldwide atmosphere are failing while environmentalism is slowly strengthening. He proposes a tenet of "balanced intake" for either shoppers and firms. we all know that we will fix things via using a high-mileage automobile, consuming in the community grown nutrition, and purchasing energy-efficient home equipment; yet those advancements are incremental, neighborhood, and inadequate. extra an important than our person efforts to reuse and recycle can be reforms within the international political economic system to minimize the inequalities of intake and proper the imbalance among starting to be economies and environmental sustainability.

By Mark Changizi
Changizi makes a speciality of 4 “why” questions:
1. Why can we see in color?
2. Why do our eyes face forward?
3. Why will we see illusions?
4. Why does studying come so clearly to us?
The imaginative and prescient Revolution explores phenomena comparable to cyclopses, peeking and plenty of extra you hadn’t even proposal to ask yourself approximately. Changizi indicates how deeply concerned those evolutionary points of our imaginative and prescient are in why we see the way in which we do—and what the long run holds for us.
The imaginative and prescient Revolution is a ebook that eventually offers recognition to what sooner than has been mostly overlooked by means of different works on human vision—a ebook that appears on the “why.”
Popper's idea of technology has been broadly misunderstood and poorly represented within the literature on philosophy of technological know-how, over the past 3 a long time. This e-book discusses the most concerns in Popper's conception of technology and, after giving a cautious characterization of every factor, examines the most objections which have been raised opposed to them and gives methods of circumventing them.
