Vuonna 2019 Kiinan Wuhanissa havaittiin uusi koronavirus SARS-Cov-2, josta on sittemmin tullut liiankin tuttu koko maailmalle. Viruksen aiheuttama COVID-19-tauti on tappanut miljoonia sekä saanut lieveilmiöineen aikaan valtavasti inhimillistä kärsimystä ja taloudellisia tappioita...

Viruses are big news. From pandemics such as HIV, swine flu, and SARS, we are constantly being bombarded with information about new lethal infections. In this Very Short Introduction, Dorothy Crawford demonstrates how clever these entities really are. From their discovery and the unravelling of their intricate structures, Crawford demonstrates how these tiny parasites are by far the most abundant life forms on the planet. 

Woher kommt Corona? SARS­CoV­2 hält seit über zwei Jahren die Welt in Atem. Doch wo liegt der Ursprung des Virus und wie genau ist es entstanden? Wie ein Krimi ­nal kommissar hat sich der erfahrene Molekular­biologe Günter Theißen auf Spurensuche begeben und seit Anbeginn der Pandemie...

Where did viruses come from? What are viruses? Are viruses life forms? Are there any bacteria that attack other cells by eating them from the inside out? Are bacteria and viruses the same thing? What are the blood cells? How does the cell know when to divide? What gives a signal? What is the signal? And how does it cause the DNA to condense? What's the difference between beneficial blood types and harmful blood types? Discover the answers to all these questions and more.

For centuries, we have viewed viruses as simple parasites—mindless invaders to be fought and eradicated. But when SARS-CoV-2 swept across the globe, adapting with seeming precision to evade our defenses, a deeper question emerged: How do entities without brains, without consciousness, without any capacity for thought, achieve outcomes that appear so intelligent?

The population is terrified by reports of so-called COVID-19, measles, swine flu, SARS, BSE, AIDS, or polio. However, the authors of "Virus Mania", investigative journalist Torsten Engelbrecht, Dr. Claus Köhnlein, MD, Dr. Samantha Bailey, MD, and Dr. Stefano Scoglio, BSc PhD, show that this fearmongering is unfounded and that virus mayhem ignores basic scientific facts: The existence, the pathogenicity and the deadly effects of these agents have never been proven.

Despite advances in health care, infectious microbes continue to be a formidable adversary to scientists and doctors. Vaccines and antibiotics, the mainstays of modern medicine, have not been able to conquer infectious microbes because of their amazing ability to adapt, evolve, and spread to new places. Terrorism aside, one of the greatest dangers from infectious disease we face today is from a massive outbreak of drug-resistant microbes.

Uncover the evolutionary arms race of virology and discover how non-living entities hijack human biology. Whether you are commuting or satisfying a deep curiosity about the natural world, this fascinating listen transforms health anxiety into profound wonder. Step into a strange realm where tiny...

In 2020, an invisible germ - a virus - wholly upended our lives. We're most familiar with the viruses that give us colds or Covid-19. But viruses also cause a vast range of other diseases, including one disorder that makes people sprout branch-like growths as if they were trees. Viruses have been a part of our lives for so long that we are actually part virus: the human genome contains more DNA from viruses than our own genes. Meanwhile, scientists are discovering viruses everywhere they look: in the soil, in the ocean, even in deep caves miles underground.

Alla fine del 2019, i medici degli ospedali di Wuhan, nella Cina centrale, si trovano ad affrontare una strana sindrome respiratoria che pare legata al grande mercato ittico della città, dove oltre al pesce si vende ogni tipo di animale commestibile, vivo o morto. Mentre i malati si moltiplicano e alcuni soccombono a una polmonite virale particolarmente aggressiva, i laboratori riescono rapidamente a isolare il responsabile della malattia: è un nuovo coronavirus, simile a quello della SARS che tra il 2002 e il 2003 aveva spaventato il mondo.

The enormous human and economic toll of the rapidly spreading COVID-19 disease offers a vivid reminder that infectious disease pandemics are one of the greatest existential threats to humanity. This book provides an accessible explanation of how viruses emerge to cause pandemics, how our immune system combats them, and how diagnostic tests, vaccines, and antiviral therapies work - concepts that are a foundation for our public health policies. 

It can come in waves - like tidal waves. It changes societies. It disrupts life. It ends lives. As far back as 3000 B.C.E. (the Bronze Age), plagues have stricken mankind. COVID-19 is just the latest example, but history shows that life continues. It shows that knowledge and social cooperation can save lives. Viruses are neither alive nor dead and are the closest thing we have to zombies. Their only known function is to replicate themselves, which can have devastating consequences on their hosts.

In a destitute hospital in the crowded African city of Kikwit, townspeople, nurses, and doctors are dying of a gruesome disease at the rate of more than a dozen a day. Zaire is on the brink of an explosive epidemic - but the outbreak is stopped when experts from the Centers for Disease Control...

I batteri sono gli esseri unicellulari più piccoli fra tutti gli organismi viventi, i virus sono organizzazioni biologiche di dimensioni addirittura inferiori a quelle della più piccola cellula batterica, ma entrambi possono infettare l'uomo, o altri animali e organismi vegetali, provocando malattie spesso gravi o addirittura letali.

How a mysterious, super-powerful—yet long-neglected—microbe rules our world and can rescue our health in the age of antibiotic resistance. At every moment, within our bodies and all around us, trillions of microscopic combatants are waging a war that shapes our health and life on Earth...

At every moment, within your body and all around you, trillions of microscopic combatants are fighting an invisible war. Countless times per second, 'good' viruses known as phages are infecting and destroying bacteria. These phages are the most abundant life form on the planet and have an incredible power to heal rather than harm. So why have most of us never even heard of them? The Good Virus reveals how personalities, power and politics have repeatedly crashed together to hinder our understanding of these weird and wonderful life forms.
