  Insects - A Very Short Introduction

  To date, more than a million insect species have been described, with probably at least another 5-8 million species waiting in the wings for a name. Insects are a fascinatingly diverse and beautiful spectrum of animals. They range in size from the tiny parasitic wasp, measuring a mere 139µm, to the aptly named Titan beetle, which can reach lengths of up to 17cm. They can be found on all continents of the world, from the Sahara Desert to the frozen wastes of Antarctica. While no insects live beneath the waves, the intrepid sea skaters skim the surface of some of the world's oceans. 
   
   
   
  This Very Short Introduction explores the extraordinary world of insects. It analyses insect evolution, taxonomy, and development, and describes their behavior, their life styles, and the interactions they have with other insects and other animals. As Simon Leather shows, insects are the bedrock on which human civilization rests; without them we would almost certainly not exist. Although they can be seen as pests of our crops plants, they are also invaluable for pollinating our flowering plants and are an invaluable link in all land ecosystems. As they face challenges from climate change and pesticides it has never been more important to understand these oft-dismissed creatures.

  Medical Microbiology - Pathogens...

  Medical microbiology is a branch of microbiology that focuses on the study of microorganisms and their role in human health and disease. It encompasses the identification, diagnosis, treatment, and prevention of infections caused by bacteria, viruses, fungi, and parasites. Understanding the fundamental principles of medical microbiology is essential for the effective diagnosis and management of infectious diseases, which continue to represent a significant global health challenge. 
  Microorganisms are ubiquitous and can be found in almost every environment on Earth, including the human body. The human microbiome, a collection of trillions of microorganisms living within and on our bodies, plays a crucial role in maintaining health. While many of these microorganisms are harmless or even beneficial, others are pathogenic and capable of causing diseases. The ability of pathogens to infect, survive, and reproduce in human hosts is the cornerstone of infectious disease. 
  The study of medical microbiology involves understanding the characteristics of pathogens, how they cause disease, and how the human immune system responds to these invaders. Pathogens are typically classified into several groups based on their structure, genetic makeup, and mode of transmission. Bacteria, for example, are single-celled organisms that can either be beneficial or harmful. Viruses, which are much smaller than bacteria, are unable to replicate on their own and require a host cell for reproduction. Fungi and parasites, which include yeasts, molds, protozoa, and helminths, also contribute to a wide variety of infections in humans.

  The Fabric of Cosmos -...

  The story of dark matter begins not in the distant reaches of the universe, but in the questions that humans have asked for centuries. What is the universe made of? Why do galaxies behave the way they do? As our tools for observing the cosmos improved, so did our understanding—but with every answer came more mystery. In the early 20th century, astronomers began to notice strange things. Galaxies were spinning in ways that defied the laws of physics, at least as we understood them. The stars on the outer edges of galaxies were moving far too fast to be held together by the gravity from visible matter alone. There had to be something else out there, something invisible, something we couldn’t detect with telescopes. This was one of the first big hints that something massive and unseen—what we now call dark matter—was shaping the universe. 
  Modern cosmology was born when scientists started to view the universe not just as a collection of stars and planets, but as a dynamic, evolving structure governed by deep physical laws. Einstein’s theory of general relativity reshaped our understanding of space, time, and gravity. Suddenly, the universe was a place where space could bend, expand, and even accelerate. These ideas led to the Big Bang theory and the realization that the cosmos had a beginning and has been changing ever since. But as astronomers began mapping out galaxies and measuring their movements, inconsistencies popped up. The math didn’t add up unless we assumed that most of the mass in the universe was missing from our view. That mass didn’t emit light, didn’t reflect it, and didn’t absorb it. It was dark, but it was there.

  A deeply moving narrative of the coronavirus pandemic, told through portraits of eight individuals who worked tirelessly to help others. In March 2020, COVID-19 overtook the United States, and life changed for America. In a matter of weeks the virus impacted millions, with lockdown measures radically reshaping the lives of even those who did not become infected. Yet despite the fear, hardship, and heartbreak from this period of collective struggle, there was hope. In The Helpers, journalist Kathy Gilsinan profiles eight individuals on the frontlines of the coronavirus battle: a devoted son caring for his family in the San Francisco Bay Area; a not-quite-retired paramedic from Colorado; an ICU nurse in the Bronx; the CEO of a Seattle-based ventilator company; a vaccine researcher at Moderna in Boston; a young chef and culinary teacher in Louisville, Kentucky; a physician in Chicago; and a funeral home director in Seattle and Los Angeles. These inspiring individual accounts create an unforgettable tapestry of how people across the country and the socioeconomic spectrum came together to fight the most deadly pandemic in a century.
