James D. Watson When, in late March of 1953, Francis Crick and I came to write the first Nature paper describing the double helical structure of the DNA molecule, Francis had wanted to include a lengthy discussion of the genetic implications of a molecule whose struc ture we had divined from a minimum of experimental data and on theoretical argu ments based on physical principles. But I felt that this might be tempting fate, given that we had not yet seen the detailed evidence from King's College. Nevertheless, we reached a compromise and decided to include a sentence that pointed to the biological significance of the molecule's key feature-the complementary pairing of the bases. "It has not escaped our notice," Francis wrote, "that the specific pairing that we have postulated immediately suggests a possible copying mechanism for the genetic material." By May, when we were writing the second Nature paper, I was more confident that the proposed structure was at the very least substantially correct, so that this second paper contains a discussion of molecular self-duplication using templates or molds. We pointed out that, as a consequence of base pairing, a DNA molecule has two chains that are complementary to each other. Each chain could then act ". . . as a template for the formation on itself of a new companion chain, so that eventually we shall have two pairs of chains, where we only had one before" and, moreover, " ...

For Blood and Money tells the little-known story of how an upstart biotechnology company created a one-in-a-million cancer drug, and how the core team-denied their share of the profits-went and did it again. In this epic saga of money and science, veteran financial journalist Nathan Vardi explains how the invention of two of the biggest cancer drugs in history became (for their backers) two of the greatest Wall Street bets of all time. In the multibillion-dollar business of biotech, where pharmaceutical companies, the government, hedge funds, and venture capitalists have spent billions on funding, experimentation, and treatments, a single molecule can stop cancer in its tracks-and make the people who find that rare molecule astonishingly rich. For Blood and Money follows a small team at a biotech start-up in California, who have found one of these rare molecules. Their compound, known as a BTK inhibitor, seems to work on a vicious type of leukemia. When patients start rising from their hospice beds, the team knows they're onto something big. What follows is a story of genius, pathos, and drama, in which vivid characters navigate a world of corporate intrigue and ambiguous morality. Vardi's narrative immerses readers in the recent explosion of biotech start-ups. He describes the scientists, doctors, and investors who are risking everything to develop new, life-saving treatments, and introduces suffering patients for whom the stakes are life-or-death. A gripping nonfiction read, For Blood and Money illustrates why it's so hard to bring new drugs to market, explains why they are so expensive, and examines how profit-driven venture capitalists are shaping the future of medicine.

Negative ions are common in solutions and important in many biological processes, but they are far less well-characterized in the gas phase compared to positive ions. One of the reasons is that it is hard to make a thermodynamically stable negative ion in the gas phase. Directly attaching a low energy electron to a molecule could produce a transient negative ion, which usually autodetaches an electron or fragments to release the excess energy. In this work, alkali metal atoms are used to collide with halogenated molecules in crossed supersonic beams. Electron transfer occurs during the collision and a positive-negative ion pair is produced. The transient negative ion can release part of its excess energy to the alkali positive ion in the form of translation and a stable negative ion could be formed. The energetics of the collision is studied and the electron affinities of the negative ions are measured. This study opens a new pathway to produce negative ions and provides insight into the electron transfer mechanism. It is useful to professionals in the field of gas phase ion chemistry, or anyone else who may be considering utilizing this method to make biological negative ions.

The rapid increase in the emergence of antibiotic-resistant bacterial strains, combined with a dwindling rate of discovery of novel antibiotic molecules, has created an alarming issue worldwide. Although the occurrence of resistance in microbes is a natural process, the overuse of antibiotics is known to increase the rate of resistance evolution. Under antibiotic treatment, susceptible bacteria inevitably die, while resistant microorganisms proliferate under reduced competition. Therefore, the out-of-control use of antibiotics eliminates drug-susceptible species that would naturally limit the expansion of resistant species. In addition, the ability of many microbial species to grow as a biofilm has further complicated the treatment of infections with conventional antibiotics. A number of corrective measures are currently being explored to reverse or slow antibiotic resistance evolution, Among which one of the most promising solutions is the development of polymer-based antimicrobial compounds. In this Special Issue, different polymer systems able to prevent or treat biofilm formation, including cationic polymers, antibacterial peptide-mimetic polymers, polymers or composites able to load and release bioactive molecules, and antifouling polymers able to repel microbes by physical or chemical mechanisms are reported. Their applications in the design and fabrication of medical devices, in food packaging, and as drug carriers is investigated.

From the Marginalian creator and bestselling author Maria Popova, a bold exploration of what makes a meaningful life. What is life? What is death? What makes a body a person? What makes a planet a world? In Traversal, Maria Popova illuminates our various instruments of reckoning with the bewilderment of being alive-our telescopes and our treatises, our postulates and our poems-through the intertwined lives, loves, and legacies of visionaries both celebrated and sidelined by history, people born into the margins of their time and place who lived to write the future: Mary Shelley, Walt Whitman, Frederick Douglass, Fanny Wright, Dorothy Crowfoot Hodgkin, Marie Tharp, Alfred Wegener, Humphry Davy, Ruth Benedict, and Margaret Mead. Woven throughout their stories are other threads-the first global scientific collaboration, the Irish potato famine, the decoding of the insulin molecule, the invention of the bicycle, how nature creates blue-to make the tapestry of meaning more elaborate yet clearer as the book advances, converging on the ultimate question of what makes life alive and worth living. By turns epic and intimate-as concerned with the physical laws binding atoms into molecules as with the psychic forces binding us to one another-Traversal explores the universe between cells and souls to reveal the world, and our lives, in a dazzling new light.

Thanks to blockbuster movies about superheroes and cloned dinosaurs, DNA now is an icon in popular culture. Yet if asked who discovered DNA, most people – including most scientists – would probably think of Watson and Crick, unaware that it all began almost a century earlier. This book tells the story of Swiss scientist Friedrich Miescher, whose pioneering work led to the discovery of DNA. Drawing on Miescher’s publications and letters, the authors trace his breakthrough – from washing pus off discarded bandages in Tübingen’s medieval castle to fishing salmon in the Rhine at dawn to study their sperm – and follow how his insights were received against a backdrop of intellectual rivalries, clashing egos, and fierce feuds that raged between disciplines. The book then explores what became of Miescher’s discovery after his death, showing how a molecule long dismissed as biologically insignificant became central to powerful technologies that now shape our future. Finally, the authors examine the ethical, social, and political questions raised by such developments and why Miescher’s story may matter today more than ever. Written in an engaging and accessible style, this account of Miescher’s groundbreaking work will captivate anyone interested in the discovery of one of biology’s most important and enigmatic molecules.

One of the main aspects of statistical mechanics is that the properties of a thermodynamics state point do not depend on the choice of the statistical ensemble. It breaks down for small systems e.g. single molecules. Hence, the choice of the statistical ensemble is crucial for the interpretation of single molecule experiments, where the outcome of measurements depends on which variables or control parameters, are held fixed and which ones are allowed to fluctuate. Following this principle, this thesis investigates the thermodynamics of a single polymer pulling experiments within two different statistical ensembles. Moreover, if polymers are charged in confinement, coarse-graining is problematic, owing to dielectric interfaces. Hence, the effect of dielectric interfaces must be taken into account when describing physical systems such as ionic channels or biopolymers inside nanopores. It is shown that the effect of dielectrics is crucial for the dynamics of a biopolymer or an ion inside a nanopore. In the simulations, the feasibility of an efficient and accurate computation of electrostatic interactions in the presence of an arbitrarily shaped dielectric domain is challenging.

DMT is known as 'The Spirit Molecule' - and for good reason. DMT is one of the most powerful psychedelics on the planet, naturally occurring in many species of plants, and is thought to be released in tiny amounts in mammal brains. Although the issue is controversial, it's also possible that the release of natural DMT is a factor in out-of-body experiences or spiritual states. DMT is a molecule that mimics the neurotransmitter serotonin, much like the other classic psychedelics LSD and psilocybin. DMT's psychological effects are mostly due to its binding to the 5-HT2A receptor, which is found mostly in areas of the brain associated with high-level cognition: self-awareness, emotions and introspection. When smoked or injected intravenously, DMT causes a very rapid, very intense psychedelic experience which lasts a few minutes. Users report the feeling of being ripped from their bodies, and thrown through space at incredible speeds. DMT produces intense visual and auditory hallucinations of otherworldly landscapes, hidden dimensions and god-like beings. It often produces deep introspection in its users, allowing the revisitation of past memories and providing a fresh perspective on life. In this book "MAKING DMT GUIDE" I will be teaching you everything in details on what you need to know about DMT. You will also learn fast and easy methods for extracting DMT and the various functions, benefits and side effects of DMT. I will also be answering all your unanswered questions as far as DMT is concerned. Order your copy Now

Clusters as mesoscopic particles represent an intermediate state of matter between single atoms and solid material. The tendency to miniaturise technical objects requires knowledge about systems which contain a "small" number of atoms or molecules only. This is all the more true for dynamical aspects, particularly in relation to the qick development of laser technology and femtosecond spectroscopy. Here, for the first time is a highly qualitative introduction to cluster physics. With its emphasis on cluster dynamics, this will be vital to everyone involved in this interdisciplinary subject. The authors cover the dynamics of clusters on a broad level, including recent developments of femtosecond laser spectroscopy on the one hand and time-dependent density functional theory calculations on the other.

Genetics, the science of heredity, has revolutionized our understanding of life. From Gregor Mendel's groundbreaking experiments with peas to the discovery of the DNA structure in the 20th century, genetic breakthroughs have fundamentally altered our knowledge of how organisms function at the molecular level. In this essay, we explore some of the most significant historical breakthroughs in genetics and illuminate their profound impact on our understanding of biology and medicine. Mendel's Pea Experiments: The Birth of Modern Genetics In the 19th century, Gregor Mendel, an Augustinian monk and naturalist, laid the foundation for modern genetics through his experiments with peas. Mendel observed that certain traits, such as the color of flower petals or the shape of seeds, were passed down from one generation to the next. Through careful analysis of his results, he formulated the Mendelian laws of inheritance, which state that genes occur in dominant and recessive alleles and that these alleles are inherited independently. Mendel's work, initially largely overlooked, is now considered one of the most important milestones in the history of science. The Discovery of DNA Structure: The Molecule of Life In the 20th century, scientists succeeded in deciphering the structure of the deoxyribonucleic acid (DNA) molecule, which holds the genetic information of all living organisms. In 1953, James Watson and Francis Crick, supported by Maurice Wilkins and Rosalind Franklin, described the double helix structure of DNA, composed of two intertwined strands. This discovery marked a turning point in biology and enabled scientists to understand the workings of genes and the mechanisms of heredity at the molecular level.

Two review papers, eight research articles, and one brief report were published in this Special Issue. They showed the rich resources that are present within the genomes of marine microorganisms and discussed the use of recently developed tools and technologies to exploit this genetic richness. Examples include the rational supply of precursors according to the relevant biosynthetic pathway and stress driven discovery together with the use of histone deacetylase inhibitors to facilitate the discovery of new bioactive molecules with potential biopharmaceutical applications. We believe that the content of this Special Issue reflects the current state-of-the-art research in this area and highlights the interesting strategies that are being employed to uncover increasing numbers of exciting novel compounds for drug discovery from marine genetic resources.

Clusters as mesoscopic particles represent an intermediate state of matter between single atoms and solid material. The tendency to miniaturise technical objects requires knowledge about systems which contain a "small" number of atoms or molecules only. This is all the more true for dynamical aspects, particularly in relation to the qick development of laser technology and femtosecond spectroscopy. Here, for the first time is a highly qualitative introduction to cluster physics. With its emphasis on cluster dynamics, this will be vital to everyone involved in this interdisciplinary subject. The authors cover the dynamics of clusters on a broad level, including recent developments of femtosecond laser spectroscopy on the one hand and time-dependent density functional theory calculations on the other.

Genetics, the science of heredity, has revolutionized our understanding of life. From Gregor Mendel's groundbreaking experiments with peas to the discovery of the DNA structure in the 20th century, genetic breakthroughs have fundamentally altered our knowledge of how organisms function at the molecular level. In this essay, we explore some of the most significant historical breakthroughs in genetics and illuminate their profound impact on our understanding of biology and medicine. Mendel's Pea Experiments: The Birth of Modern Genetics In the 19th century, Gregor Mendel, an Augustinian monk and naturalist, laid the foundation for modern genetics through his experiments with peas. Mendel observed that certain traits, such as the color of flower petals or the shape of seeds, were passed down from one generation to the next. Through careful analysis of his results, he formulated the Mendelian laws of inheritance, which state that genes occur in dominant and recessive alleles and that these alleles are inherited independently. Mendel's work, initially largely overlooked, is now considered one of the most important milestones in the history of science. The Discovery of DNA Structure: The Molecule of Life In the 20th century, scientists succeeded in deciphering the structure of the deoxyribonucleic acid (DNA) molecule, which holds the genetic information of all living organisms. In 1953, James Watson and Francis Crick, supported by Maurice Wilkins and Rosalind Franklin, described the double helix structure of DNA, composed of two intertwined strands. This discovery marked a turning point in biology and enabled scientists to understand the workings of genes and the mechanisms of heredity at the molecular level.
