"90 Miles to Havana" is a 2011 Pura Belpre Honor Book for
Narrative and a 2011 Bank Street Best Children's Book of the
Year.
When Julian's parents make the heartbreaking decision to send him
and his two brothers away from Cuba to Miami via the Pedro Pan
operation, the boys are thrust into a new world where bullies run
rampant and it's not always clear how best to protect
themselves.
The cyanobacteria are a fascinating group of bacteria that have
adapted to colonize almost every environment on the planet. They
are the only prokaryotes capable of oxygenic photosynthesis,
responsible for up to 20-30% of Earth's photosynthetic
productivity. They can attune their light-harvesting systems to
changes in available light conditions, fix nitrogen, and have
circadian rhythms. In addition, many cyanobacteria species exhibit
gliding mobility and can differentiate into specialized cell types
called heterocysts, and some are symbiotic. Thanks to their simple
nutritional requirements, their metabolic plasticity, and the
powerful genetics of some model strains, cyanobacteria could be
exploited for use as microbial cell factories for carbon capture
and storage, and for the sustainable production of secondary
metabolites and biofuels. Understanding their cell biology is an
essential step to achieving this. In this book, leading senior
scientists and young researchers review the current key topics in
cyanobacterial cell biology to provide a timely overview. Topics
covered include: historical background * cell division * the cell
envelope * the thylakoid membrane * protein targeting, transport,
and translocation * chromatic acclimation * the carboxysome *
glycogen as a dynamic storage of photosynthetically fixed carbon *
cyanophycin * gas vesicles * motility in unicellular and
filamentous cyanobacteria * cellular differentiation in filamentous
cyanobacteria * cell-cell joining proteins in heterocyst-forming
cyanobacteria. This cutting-edge text will provide a valuable
resource for all those working in this field and is recommended for
all microbiology libraries.

Cyanobacteria are a fascinating and versatile group of bacteria of
immense biological importance. Thought to be amongst the first
organisms to colonize the earth, these bacteria are the
photosynthetic ancestors of chloroplasts in eukaryotes, such as
plants and algae. In addition, they can fix nitrogen, survive in
very hostile environments (e.g. down to -60-degreesC), are
symbiotic, have circadian rhythms, exhibit gliding mobility, and
can differentiate into specialized cell types called heterocysts.
This makes them ideal model systems for studying fundamental
processes, such as nitrogen fixation and photosynthesis. In
addition, cyanobacteria produce an array of bioactive compounds,
some of which could become novel anti-microbial agents, anti-cancer
drugs, UV protectants, etc. The amazing versatility of
cyanobacteria has attracted huge scientific interest in recent
years. Given that 24 genomes sequences have been completed and many
more projects are currently underway, the point has been reached
where there is an urgent need to summarize and review the current
molecular biology, genomics, and evolution of these important
organisms. This volume brings together the expertise and enthusiasm
of an international panel of leading cyanobacterial researchers to
provide a state-of-the art overview of the field. Topics covered
include: evolution, comparative genomics, gene transfer, molecular
ecology and environmental genomics, stress responses, bioactive
compounds, circadian clock, structure of the photosynthetic
apparatus, membrane systems, carbon acquisition, nitrogen
assimilation, C/N balance sensing, and much more. This book will be
essential for anyone with an interest in cyanobacteria, bacterial
photosynthesis, bacterial nitrogen fixation, and symbiosis.
