'Steve Brusatte, the author of The Rise and Fall of the Dinosaurs,
brings mammals out from the shadow of their more showy predecessors
in a beautifully written book that . . . makes the case for them as
creatures who are just as engaging as dinosaurs.' - The Sunday
Times, 'Best Books For Summer' 'In this terrific new book, Steve
Brusatte . . . brings well-known extinct species, the sabre-toothed
tigers and the woolly mammoths, thrillingly back to life' - The
Times The passing of the age of the dinosaurs allowed mammals to
become ascendant. But mammals have a much deeper history. They -
or, more precisely, we - originated around the same time as the
dinosaurs, over 200 million years ago; mammal roots lie even
further back, some 325 million years. Over these immense stretches
of geological time, mammals developed their trademark features:
hair, keen senses of smell and hearing, big brains and sharp
intelligence, fast growth and warm-blooded metabolism, a
distinctive line-up of teeth (canines, incisors, premolars,
molars), mammary glands that mothers use to nourish their babies
with milk, qualities that have underlain their success story. Out
of this long and rich evolutionary history came the mammals of
today, including our own species and our closest cousins. But
today's 6,000 mammal species - the egg-laying monotremes including
the platypus, marsupials such as kangaroos and koalas that raise
their tiny babies in pouches, and placentals like us, who give
birth to well-developed young - are simply the few survivors of a
once verdant family tree, which has been pruned both by time and
mass extinctions. In The Rise and Reign of the Mammals,
palaeontologist Steve Brusatte weaves together the history and
evolution of our mammal forebears with stories of the scientists
whose fieldwork and discoveries underlie our knowledge, both of
iconic mammals like the mammoths and sabre-toothed tigers of which
we have all heard, and of fascinating species that few of us are
aware of. For what we see today is but a very limited range of the
mammals that have existed; in this fascinating and ground-breaking
book, Steve Brusatte tells their - and our - story.
Diagnosis of death by neurological criteria (DNC) is a construct
which has been part of the British medico-legal landscape for
nearly half a century. This book examines the factors behind its
emergence, and discusses the various changes that took place in the
last few decades that culminated in the current definition and
clinical criteria for determining brain-based death. It highlights
the continuities and discontinuities in practice, and the impact
they have on the issue of withdrawal of mechanical ventilation in
intensive care units and on the field of organ transplantation. The
book also explores the law's response to the introduction and
development of DNC in clinical practice. It demonstrates how the
legitimacy of the definition and criteria used by the medical
profession were forged in the courtroom rather than in Parliament.
It documents why case law were introduced in court, and assesses
whether organ donation was a consideration in the deliberations. It
will be emphasised that courts have given insufficient
consideration to requests made in recent cases to consider a
broader range of methods to determine death. Those pleas were made
on the grounds that the definition and criteria used in the UK are
dissimilar to those used in other jurisdictions that also adopt
DNC; and that faith communities have a different understanding of
death. By taking a close look at those other approaches before
highlighting the inherent limitations of the courtroom as the forum
that confers DNC its legitimacy, the book puts forward the argument
that the democratic process should be engaged.
The kidney is innervated with efferent sympathetic nerve fibers
reaching the renal vasculature, the tubules, the juxtaglomerular
granular cells, and the renal pelvic wall. The renal sensory nerves
are mainly found in the renal pelvic wall. Increases in efferent
renal sympathetic nerve activity reduce renal blood flow and
urinary sodium excretion by activation of 1-adrenoceptors and
increase renin secretion rate by activation of 1-adrenoceptors. In
response to normal physiological stimulation, changes in efferent
renal sympathetic nerve activity contribute importantly to
homeostatic regulation of sodium and water balance. The renal
mechanosensory nerves are activated by stretch of the renal pelvic
tissue produced by increases in renal pelvic tissue of a magnitude
that may occur during increased urine flow rate. Under normal
conditions, the renal mechanosensory nerves activated by stretch of
the sensory nerves elicits an inhibitory renorenal reflex response
consisting of decreases in efferent renal sympathetic nerve
activity leading to natriuresis. Increasing efferent sympathetic
nerve activity increases afferent renal nerve activity which, in
turn, decreases efferent renal sympathetic nerve activity by
activation of the renorenal reflexes. Thus, activation of the
afferent renal nerves buffers changes in efferent renal sympathetic
nerve activity in the overall goal of maintaining sodium balance.
In pathological conditions of sodium retention, impairment of the
inhibitory renorenal reflexes contributes to an inappropriately
increased efferent renal sympathetic nerve activity in the presence
of sodium retention. In states of renal disease or injury, there is
a shift from inhibitory to excitatory reflexes originating in the
kidney. Studies in essential hypertensive patients have shown that
renal denervation results in long-term reduction in arterial
pressure, suggesting an important role for the efferent and
afferent renal nerves in hypertension.
This highly interdisciplinary book discusses the phenomenon of
life, including its origin and evolution, against the background of
thermodynamics, statistical mechanics, and information theory.
Among the central themes is the seeming contradiction between the
second law of thermodynamics and the high degree of order and
complexity produced by living systems. As the author shows, this
paradox has its resolution in the information content of the Gibbs
free energy that enters the biosphere from outside sources. Another
focus of the book is the role of information in human cultural
evolution, which is also discussed with the origin of human
linguistic abilities. One of the final chapters addresses the
merging of information technology and biotechnology into a new
discipline - bioinformation technology.This third edition has been
updated to reflect the latest scientific and technological
advances. Professor Avery makes use of the perspectives of famous
scholars such as Professor Noam Chomsky and Nobel Laureates John
O'Keefe, May-Britt Moser and Edward Moser to cast light on the
evolution of human languages. The mechanism of cell
differentiation, and the rapid acceleration of information
technology in the 21st century are also discussed.With various
research disciplines becoming increasingly interrelated today,
Information Theory and Evolution provides nuance to the
conversation between bioinformatics, information technology, and
pertinent social-political issues. This book is a welcome voice in
working on the future challenges that humanity will face as a
result of scientific and technological progress.

'Compelling and wise and rational.' - Jon Ronson Motion sickness.
Nightmares. Forgetting people's names. Why did I walk into this
room?? For something supposedly so brilliant and evolutionarily
advanced, the human brain is pretty messy, fallible and
disorganised. In The Idiot Brain neuroscientist Dean Burnett
celebrates the imperfections of the human brain in all their glory,
and the impact of these quirks on our daily lives. Expertly
researched and entertainingly written, this book is for anyone who
has wondered why their brain seems to be sabotaging their life, and
what on earth it is really up to.
The protein molecule is the basic building block of every living
entity. Its deficiency leads to restricted growth and development
of individuals. Globally, such malnutrition is on the rise due to
various reasons such as rapid population growth, stagnation of
productivity, and ever-rising costs. Millions of people, especially
in developing and under-developed countries, suffer from protein
malnutrition and the only possible solution is to encourage farmers
to grow high-protein food legume crops in their fields for domestic
consumption. This, however, could be possible if farmers are
provided with new cultivars with high yield, and resistance to
major insects, diseases, and key abiotic stresses. The major food
legume crops are chickpea, cowpea, common bean, groundnut, lentil,
pigeonpea, and soybean. Predominantly, the legume crops are grown
under a subsistence level and, therefore, in comparison to cereals
and horticultural crops their productivity is low and highly
variable. The crop breeders around the globe are engaged in
breeding suitable cultivars for harsh and changing environments but
success has been limited and not up to needs. With the recent
development of new technologies in plant sciences, efforts are
being made to help under-privileged farmers through breeding new
cultivars which will produce more protein per unit of land area. In
this book, the contributors analyze the constraints, review new
technologies, and propose a future course of crop breeding programs
in seven cold and warm season legume crops.

This volume brings together the latest basic and clinical research
examining the effects and underlying mechanisms of psychedelic
drugs. Examples of drugs within this group include LSD, psilocybin,
and mescaline. Despite their structural differences, these
compounds produce remarkably similar experiences in humans and
share a common mechanism of action. Commonalities among the
substances in this family are addressed both at the clinical and
phenomenological level and at the basic neurobiological mechanism
level. To the extent possible, contributions relate the clinical
and preclinical findings to one another across species. The volume
addresses both the risks associated with the use of these drugs and
the potential medical benefits that might be associated with these
and related compounds.
The 2021 IPCC report made one thing crystal clear - global climate
change is here to stay. Time is up. We need to act or climate
change will lead to inconceivable suffering by billions of people.
Buying Time for Climate Action is the combined narrative of world
class experts, all committed to help humanity survive its largely
self-induced destructive course. Changing that course requires
urgent action. Determining which actions will lead to helpful
change requires insights into the stumbling blocks that always
emerge when actions aimed at change are planned, resulting in lost
time. The experts who contributed to this volume, through their
expertise, networks, wisdom and creativity, have largely concluded
that the way to cope with the stumbling blocks is to avoid them by
focusing on grassroots initiatives. Their narratives and
discussions, presented in this book, highlight such thinking.The
book is essential reading for anyone committed to help avoid an
existential disaster for humanity, and ready to move plans into
effective action.
