Why do we die? Do all living creatures share this fate? Is the
body's slow degradation with the passage of time unavoidable, or
can the secrets of longevity be unlocked? Over the past two
decades, scientists studying the workings of genes and cells have
uncovered some of the clues necessary to solve these mysteries. In
this fascinating and accessible book, two neurobiologists share the
often-surprising findings from that research, including the
possibility that aging and natural death may not be forever a
certainty for most living beings. Andre Klarsfeld and Frederic
Revah discuss in detail the latest scientific findings and views on
death and longevity. They challenge many popular assumptions, such
as the idea that the death of individual organisms serves to
rejuvenate species or that death and sexual reproduction are
necessarily linked. Finally, they describe current experimental
approaches to postpone natural death in lower organisms as well as
in mammals. Are all organisms that survive until late in life
condemned to a "natural" death, as a consequence of aging, even if
they live in a well-protected, supportive environment? The
variability of the adult life span from a few hours for some
insects to more than a millennium for the sequoia and thirteen
times that for certain wild berry bushes challenges the notion that
death is unavoidable. Evolutionary theory helps explain why and how
some species have achieved biological mechanisms that seemingly
allow them to resist time. Death cannot be understood without
looking into cells the essential building blocks of life.
Intriguingly, at the level of cells, death is not always an
accident; it is often programmed as an indispensable aspect of
life, which benefits the organism as a whole."
Richard D. Alexander is an accomplished entomologist who turned his
attention to solving some of the most perplexing problems
associated with the evolution of human social systems. Using
impeccable Darwinian logic and elaborating, extending and adding to
the classic theoretical contributions of pioneers of behavioral and
evolutionary ecology like George Williams, William Hamilton and
Robert Trivers, Alexander developed the most detailed and
comprehensive vision of human social evolution of his era. His
ideas and hypotheses have inspired countless biologists,
anthropologists, psychologists and other social scientists to
explore the evolution of human social behavior in ever greater
detail, and many of his seminal ideas have stood the test of time
and come to be pillars of our understanding of human social
evolution. This volume presents classic papers or chapters by Dr.
Alexander, each focused on an important theme from his work.
Introductions by Dr. Alexander's former students and colleagues
highlight the importance of his work to the field, describe more
recent work on the topic, and discuss current issues of contention
and interest.

This book looks at how the human brain got the capacity for
language and how language then evolved. Its four parts are
concerned with different views on the emergence of language, with
what language is, how it evolved in the human brain, and finally
how this process led to the properties of language. Part I
considers the main approaches to the subject and how far language
evolved culturally or genetically. Part II argues that language is
a system of signs and considers how these elements first came
together in the brain. Part III examines the evidence for brain
mechanisms to allow the formation of signs. Part IV shows how the
book's explanation of language origins and evolution is not only
consistent with the complex properties of languages but provides
the basis for a theory of syntax that offers insights into the
learnability of language and to the nature of constructions that
have defied decades of linguistic analysis, including including
subject-verb inversion in questions, existential constructions, and
long-distance dependencies. Denis Bouchard's outstandingly original
account will interest linguists of all persuasions as well as
cognitive scientists and others interested in the evolution of
language.
Collectively, the chapters in this work will provide the reader
with novel insight into the inter-relationships of the function of
different organelles in the sequences of events that lead to
cellular dysfunction and degeneration in the aging human
population. The chapters are rich in information for cell and
molecular biologists pursuing studies of the different diseases
covered. In addition, the clinician will find value in
understanding mechanisms underlying age-related disease as such an
understanding will lead to novel therapeutic approaches for an
array of age-related diseases.
Sweating may be one of our weirdest biological functions, but it's
also one of our most vital and least understood. In The Joy of
Sweat, Sarah Everts delves into its role in the body-and in human
history. Why is sweat salty? Why do we sweat when stressed? Why do
some people produce colourful sweat? And should you worry about Big
Brother tracking the hundreds of molecules that leak out in your
sweat-not just the stinky ones or alleged pheromones-but the ones
that reveal secrets about your health and vices? Everts's
entertaining investigation takes readers around the world-from
Moscow, where she participates in a dating event in which people
sniff sweat in search of love, to New Jersey, where companies hire
trained armpit sniffers to assess the efficacy of their anti-sweat
products. In Finland, Everts explores the delights of the legendary
smoke sauna and the purported health benefits of good sweat, while
in the Netherlands she slips into the sauna theatre scene, replete
with costumes, special effects and towel dancing. Along the way,
Everts traces humanity's long quest to control sweat, culminating
in the multibillion-dollar industry for deodorants and
antiperspirants. And she shows that while sweating can be annoying,
our sophisticated temperature control strategy is one of humanity's
most powerful biological traits. Deeply researched and written with
great zest, The Joy of Sweat is a fresh take on a gross but
engrossing fact of human life. The New York Times Most Anticipated
Book of the Summer
This volume of "Advances in Cell Aging and Gerontology" critically
reviews the rapidly advancing area of telomerase research with a
focus at the molecular and cellular levels. The clearly established
function of telomerase is to maintain chromosome ends during
successive rounds of cell division by adding a six base DNA repeat
on to the telomeric ends of chromosomes. As presented in the
chapters of this volume, the mechanisms that regulate telomerase
expression and activity are complex. Moreover, emerging data
suggest additional roles for telomerase in the regulation of cell
differentiation and survival.
It is expected that this quite comprehensive volume will provide a
valuable resource for graduate students and postdocs in the
telomerase field and for established investigators in other fields
who are beginning to study telomerase in their particular research
program. With an increasing number of proteins being brought into
the fold of telomerase research (e.g., DNA damage and repair
response proteins, heat-shock proteins, and proteins in various
signal transduction cascades) many new scientists are beginning to
study this enzyme from novel vantage points.
This book reconstructs what the earliest grammars might have been
and shows how they could have led to the languages of modern
humankind.
Like other biological phenomena, language cannot be fully
understood without reference to its evolution, whether proven or
hypothesized," wrote Talmy Givon in 2002. As the languages spoken
8,000 years ago were typologically much the same as they are today
and as no direct evidence exists for languages before then,
evolutionary linguists are at a disadvantage compared to their
counterparts in biology. Bernd Heine and Tania Kuteva seek to
overcome this obstacle by combining grammaticalization theory, one
of the main methods of historical linguistics, with work in animal
communication and human evolution. The questions they address
include: do the modern languages derive from one ancestral language
or from more than one? What was the structure of language like when
it first evolved? And how did the properties associated with modern
human languages arise, in particular syntax and the recursive use
of language structures? The authors proceed on the assumption that
if language evolution is the result of language change then the
reconstruction of the former can be explored by deploying the
processes involved in the latter. Their measured arguments and
crystal-clear exposition will appeal to all those interested in the
evolution of language, from advanced undergraduates to linguists,
cognitive scientists, human biologists, and archaeologists.
During the past several years there has been a shortage of flight
opportunities for biological and medical projects. And those that
were available usually had severe restrictions on instrumentation,
number of subjects, duration, time allotted for performing the
experiments, a possibility for repetition of experiments. It is our
hope and expectation that this will change once the international
Space Station is in full operation. The advantages of a permanent
space station, already demonstrated by the Russian Mir station, are
continuous availability of expert crew and a wide range of
equipment, possibility of long-term experiments where this is
waranted, increased numbers of subjects through larger laboratory
space, proper controls in the large 1-G centrifuge, easier
repeatability of experiments when needed.
The limited number of flight opportunities during recent years
probably explains why it has taken so long to acquire a sufficient
number of high quality contributions for this seventh volume of
Advances in Space Biology and Medicine. While initially the series
wassailed at annually appearing volumes, we are now down to a
biannual appearance. Hopefully, it will be possible to return to
annual volumes in the future when results from space station
experimentation at beginning to pour in.
The first three chapters of this volume deal with muscle. Fejtek
and Wassersug provide a survey of all studies on muscle of rodents
flown in space, and include an interesting demography of this
aspect of space research. Riley reviews our current knowledge of
the effects of long-term spaceflight and re-entry on skeletal
muscle, and considers the questions still to be answered before we
can be satisfied that long-term space missions, such as on the
space station, can be safely undertaken. Stein reviews our
understanding of the nutritional and hormonal aspects of muscle
loss in spaceflight, and concludes that the protein loss in space
could be deleterious to health during flight and after return.
Strollo summarizes our understanding of the major endocrine systems
on the ground, then considers what we know about their functioning
in space, concluding that there is much to be learned about the
changes taking place during spaceflight. The many problems of
providing life support (oxygen regeneration and food supply) during
extended stay on the Moon, on Mars, or in space by means of plant
cultivation are discussed by Salisbury. The challenges of utilizing
electrophoresis in microgravity for the separation of cells and
proteins are illustrated and explained by Bauer and colleagues.
Finally, the chapter on teaching of space life sciences by Schmitt
shows that this field of science has come of age, but also that its
multidisciplinary character poses interesting challenges to
teaching it.
Gray's Anatomy, published in the UK in 1858 under the original
title Anatomy: Descriptive and Surgical, is a detailed English
textbook on human anatomy, focused on teaching medical students
human anatomy for practical knowledge during surgery. This unique
first edition includes more than 300 pages of illustrations by H.V.
Carter, M.D. Each image is labeled with the corresponding bones,
muscles, nerves, and organs. In addition, the book is separated
into chapters based on the systems of the body for easy use. While
Gray's Anatomy may no longer be a suitable study guide for modern
physicians, it is considered a classic work on the subject and is a
great reference for those interested in the origins of the study of
human anatomy. HENRY GRAY (1827-1861) was a renowned British
anatomist who studied at St George's Hospital Medical School in
London. His focus was on the endocrine glands and spleen until he
approached fellow colleague Henry Vandyke Carter to help him write
a comprehensive and accessible anatomy textbook. The team worked
for more than a year studying unclaimed cadavers to help write the
text. It was published in England in 1858 and in America only one
year later. Gray published the first two editions before it was
acquired by Longman's in 1863, shortly after Gray's early death
from smallpox.
The leading scholars in the rapidly-growing field of language evolution give readable accounts of their theories on the origins of language and reflect on the most important current issues and debates. As well as providing a guide to their own published research in this area they highlight what they see as the most relevant research of others. The authors come from a wide range of disciplines involved in language evolution including linguistics, cognitive science, computational science, primatology, and archaeology.
Living organisms exhibit specific responses when confronted with
sudden changes in their environmental conditions. The ability of
the cells to acclimate to their new environment is the integral
driving force for adaptive modification of the cells. Such
adaptation involves a number of cellular and biochemical alteration
including metabolic homeostasis and reprogramming of gene
expression. Changes in metabolic pathways are generally short-lived
and reversible, while the consequences of gene expression are a
long-term process and may lead to permanent alternation in the
pattern of adaptive responses.
The heart possesses remarkable ability to adapt itself against any
stressful situation by increasing resistance to the adverse
consequences. Stress composes the foundation of many degenerative
heart diseases including atherosclerosis, spasm, thrombosis,
cardiomyopathy, and congestive heart failure. Based on the concept
that excessive stress may play a crucial role in the pathogenesis
of ischemic heart disease, attempts were made to design methods for
preventing of myocardial injury. Creation of stress reactions by
repeated ischemia and reperfusion or subjecting the hearts to heat
or oxidative stress enables them to meet the future stress
challenge. Repeated stress exposures adapt the heart to withstand
more severe stress reactions probably by upregulating the cellular
defense and direct accumulation of intracellular mediators, which
presumably constitute the material basis of increased adaptation to
stress. Thus, the powerful cardioprotective effect of adaptation is
likely to originate at the cellular and molecular levels that
compose fundamental processes in the prophylaxis of such diseases.
Volume six of the Advances in Organ Biology series contains
state-of-the-art reviews on myocardial preservation and cellular
adaptation from the leading authorities in this subject.
Breast cancer research has never been in such an exciting and
hopeful phase as today. From a clinical perspective, the discovery
of genetic markers of risk in a proportion of familial breast
cancer cases has opened up new vistas for understanding and
ultimately preventing this disease. On the other hand, aggressive -
even daring - therapies are being proven to be effective against
advanced breast cancer. For the breast cancer experimentalist, this
is also a time of great advance. Although animal and cell culture
breast cancer models have proven to be of great use, there are now
increasing opportunities to test the concepts developed in these
models in actual clinical samples and cases. It is gratifying to
see how well these concepts "translate" into the clinical setting.
A very active area of research that is linking the laboratory to
the clinic is the dissection of the biology and elucidation of the
significance of proliferate breast disease and the identification
of true, "high risk" or "preneoplastic" legions within the
previously ill-defined spectrum of fibrocystic or benign breast
disease. One anticipates that discoveries made here will also lead
to earlier detection, intervention and prevention of
life-threatening cancer.
Even, however, as we look with optimism to the eventual eradication
of breast cancer, we are once again forced to face the reality that
we have not yet achieved our goal. Thus, we are saddened by the
much too premature death of Dr. Helene Smith from breast cancer.
Helena's work was at the forefront of efforts to understand the
biology of human breast cancer at the molecular level. Her insight,
open-mindedness, and refusal to sacrifice relevance for convenience
will continue to set the standard for all breast cancer
researchers. This volume is dedicated to her memory.
