Aliens is a highly debated topic, sometimes in favour others against it. Once again, we introduce more than fifty bioenergemal communications (BELCs) that for over the years we have presumably had, amongst others, with the bioenergeme of Khriannia, an extraterrestrial woman, occasionally with some of her close relatives and acquaintances, too, and finally with the bioenergeme of Bhrikiam, an extraterrestrial man. Both said to come from a planet named Agram, located in Andromeda constellation of the Milky Way. Besides, we have had BELCs with several alien civilizations. This rich bioinformation is exclusive of this book.

La scienza del mondo vivente ha assunto il nome di biologia nei primi anni del XIX secolo. Fino ad allora solo pochissimi autori avevano indicato la necessita di riconoscere, con la stessa dignita di altre discipline come lastronomia o la chimica, una scienza dedicata allo studio di tutti i viventi, e solo di questi. La prima parte del volume delinea il percorso che, da Linneo a Darwin, ha portato la biologia a diventare una scienza autonoma, mentre la seconda e dedicata alla situazione attuale della biologia e della filosofia della biologia. In entrambe le aree disciplinari, le generalizzazioni ingiustificate che spesso discendono dalleccessiva importanza attribuita ai risultati delle ricerche condotte su un piccolo numero di specie modello sono allordine del giorno. Come potra in futuro la biologia dirsi veramente generale se non interessandosi ai fenomeni della vita nel loro intero spettro di variazione presso gli animali, le piante, i funghi e tutti gli altri organismi viventi? Le riflessioni conclusive del saggio vertono su alcune scelte di fondo, concettuali e operative insieme, che possano rispondere a questa esigenza. Alessandro Minelli, gia professore ordinario di Zoologia allUniversita di Padova, si e occupato a lungo di sistematica zoologica, filogenesi e biodiversita, per poi indirizzarsi verso la biologia evoluzionistica dello sviluppo e la filosofia della biologia. Tra le sue pubblicazioni, The Development of Animal Form, Forme del divenire, Plant Evolutionary Developmental Biology. Nel recente volume Biologia della riproduzione ha inteso riscrivere, insieme a Giuseppe Fusco, un capitolo della biologia secondo una visione che tende a superare le tradizioni specialistiche legate ai diversi gruppi di viventi.

Bioluminescence, the cold living light or the cold fire of the sea, is extremely common in all oceans at all depths. However, this phenomenon is nearly absent in freshwater, with the exception of a freshwater limpet. More than 75% of deep-sea creatures have been reported to produce their own light. The luminescent marine plankton such as dinoflagellate, radiolarians, jellyfish, comb jellies, annelids, copepods, ostracods, mysids, amphipods, euphausiids, and tunicates form an important component in the marine food chain. Research on luminescent marine plankton is gaining momentum owing to its importance in life science research and medicine. The glowing Green Fluorescent Protein (GFP) extracted from the North Pacific jellyfish, Aqueorea victoria (for which the Japanese biologist, Osamu Shimonmura won the Nobel Prize in Chemistry in 2008) has helped shed light on key processes such as the spread of cancer, the development of brain cells, the growth of bacteria, damage to cells by Alzheimers disease, and the development of insulin-producing cells in the pancreas. Therefore, it is difficult to underscore the importance of bioluminescence and the organisms associated with this phenomenon. Bioluminescent Marine Plankton is a unique reference that attempts to provide answers to questions about bioluminescence. The first of its kind, this book attempts to answer questions on the subject with a focus on planktonic organisms. 12 chapters provide information about the chemistry of bioluminescence, types of bioluminescent displays, distribution of bioluminescence among marine plankton, ecological functions and utility of planktonic bioluminescence. Chapters are dedicated to the biology and ecology of specific groups of plankton that span about 200 luminescent marine species. The detailed book is an essential compendium on marine plankton for a broad range of readers who want to learn about bioluminescent plankton. A list of detailed references is also provided for the benefit of teachers, students, researchers and enthusiasts interested in marine biology, aquaculture, and environmental sciences.

Bio-based polymers are materials that are produced from renewable resources. Their biodegradable properties are the driver of worldwide interest among researchers and manufacturers in recent years due to the demand and need for alternatives to fossil fuel based polymers. The use of biodegradable polymers creates a sustainable industry. In contrast, the raw materials for synthetic polymers derived from petrochemicals will eventually deplete and most of them are non-biodegradable. Despite these advantages, bio-based polymers account for only a tiny fraction of the total global plastic market. Non-biodegradability issues of synthetic pharmaceutical inactive ingredients strongly emphasized innovators towards the development of biopolymers. Recently natural biodegradable excipients gained significant attention due to their sustainability and engineered applications. Innovative technologies to transform these materials into value-added chemicals via novel graft-polymerization or co-processing techniques for the production of high-performance multifunctional and low-cost polymers with tunable structures are key parts of its sustainable development. Biopolymers Towards Green and Sustainable Development elaborates on important issues that surround bio-based polymers. It gives the reader an overview of biopolymers, the impact of non-biodegradable polymers on the environment and health, emerging sources of biodegradable polymers, structural and morphological characterization techniques, thermomechanical properties, biodegradable plastics from biopolymers, pharmaceutical, biomedical, and textile applications, and pharmacokinetics and pharmacodynamics. Moreover, a brief bibliometric meta-analysis on bio-based pharmaceutical excipients provides an update about teams involved in the development of polymeric research that may be of interest to anyone who wants to work on sustainable biopolymer projects. Key Features - provides an updated summary on recently discovered natural polymeric materials- gives a thorough breakdown of the vast range of biopolymer applications including fabrication of conventional and novel drug delivery, polymeric scaffolds, composites, microneedles, and green synthesis of metallic nanoparticles,- summarizes pharmacology and pharmacokinetics of the inactive pharmaceutical ingredient and excipients- presents a bibliometric meta-analysis indicating potential collaboration between country, organization, institution, and authors with a view on recent ongoing trends in tyhe biopolymer landscape.

Increased industrial and agricultural activity has led to the contamination of the earths soil and groundwater resources with hazardous chemicals. The presence of heavy metals, dyes, fluorides, dissolved solids, and many other pollutants used in industry and agriculture are responsible for hazardous levels of water pollution. The removal of these pollutants in water resources is challenging. Bioremediation is a new technique that employs living organisms, usually bacteria and fungi, to remove pollutants from soil and water, preferably in situ. This approach is more cost-effective than traditional techniques, such as incineration of soils and carbon filtration of water. It requires understanding how organisms consume and transform polluting chemicals, survive in polluted environments, and how they should be employed in the field. Bioremediation for Environmental Pollutants discusses the latest research in green chemistry and practices and principles involved in quality improvement of water by remediation. It covers different aspects of environmental problems and their remedies with up-to-date developments in the field of bioremediation of industrial/environmental pollutants. Volume 1 focuses on the bioremediation of heavy metals, pesticides, textile dyes removal, petroleum hydrocarbon, microplastics and plastics. This book is invaluable for researchers and scientists in environmental science, environmental microbiology, and waste management. It also serves as a learning resource for graduate and undergraduate students in environmental science, microbiology, limnology, freshwater ecology, and microbial biotechnology.
