The book discusses the ways in which high hydrostatic pressure (i.e. water pressure) affects all grades of life which thrive at pressures much greater those in our normal environment. The deep sea is the best known high pressure environment, where pressures reach a thousand times greater than those at the surface, yet it is populated by a variety of animals and microorganisms. The earth's crust supports microorganisms which live in water filled pores at high pressure. In addition, the load bearing joints of animals like ourselves experience pulses of hydrostatic pressure of a magnitude similar to the pressure at mid ocean depths.
These pressures affect molecular structures and biochemical reactions. Basic cellular processes are drastically affected - the growth and division of cells, the way nerves conduct impulses and the chemical reactions which provide energy. Adaptation to high pressure also occurs in complex physiological systems such as those which provide buoyancy. Probably the greatest challenge to our understanding of adaptation to high pressure is the stabilisation of the nervous system of deep sea animals to avoid convulsions which pressure causes in shallow water animals.
Additionally the book provides insight into the engineering required to study life at high pressure: equipment which can trap small deep sea animals and retrieve them at their high pressure, equivalent equipment for microorganisms, laboratory microscopes which can focus on living cells under high pressure, incubators for bacteria which require high pressure to grow, high pressure aquaria for marine animals and lastly and briefly, manned and unmanned submersible vessels, Landers and deep drill hole sampling. Rather like the organisms studied many laboratory instruments have been adapted to function at high pressure.
Dr. Alister Macdonald graduated in Zoology at Bristol University. After post doctoral research at the University of East Anglia he moved to Aberdeen University, becoming Reader In Physiology in 1984. His work on deep sea animals with Dr. I Gilchrist tackled the recovery of small animals without decompression, their tolerance to pressure and recovery from decompression paralysis. Additionally, he demonstrated homeoviscous adaptation of deep sea fish membranes to high pressure. Work at sea alternated with laboratory studies of cellular processes at high pressure; membrane bilayers, membrane bound enzymes, ionic regulation, electrophysiology - latterly patch clamp studies of various ion channels and of anaesthetic - ion channel interactions. Collaboration with much valued students and senior colleagues was a key part of this wide range of activity, involving The Woods Hole Oceanographic Institution (USA) and the Bermuda Marine Biological Station for Research, The Rowett Research Institute and the Marine Laboratory, (both in Aberdeen), Queen's University, Belfast, Brunel University, and the Universities of Liverpool, Nottingham, North Carolina and Western Australia, The Babraham Institute, Cambridge, and the Max-Planck Institute for Biophysical Chemistry, Gtingen, Germany.

Most authentic book compilation on the Oregon Trail I ever read. The way the diaries are brought to life from over 170 years ago is a remarkable achievement. Top book of year so far for me for today June 01, 2024 review Candice
This author is a breathe of fresh air in a world of lies and coverups. He brings ancient writings and new science to bring light to mankind. In this amazing work, the well known plato stories from antiquity are now put alongside this new discovery of tablets from beginning of time. This is the most complete explanation of Atlantis every brought to the public. Shame on the governments of Egypt and the world for hiding WHO BUILT THE PHYRAMIDS OF GIZA AND THE SPHINX. Once I read this book I knew why they hid this knowledge. They don't want a population to know how great the world used to be compared to know.
Randomly stumbled upon this book and I am shocked that I haven’t heard about it before. It’s hands down the best story I’ve read in years. People need to read this book. It needs to be turned into a book. This story is just plain awsome. M
This soulful book of personal poetry brought me into the past and into the present---and into my heart.
Read the first book and this 2nd one did not disappoint! Loved every chapter. More please!
