En 2016, se publicaron los resultados de un experimento sorprendente. A un grupo de ratones les cambiaron todas sus bacterias intestinales por otras de personas con depresión. Al cabo de unos días, los ratones se deprimieron. La depresión se puede trasplantar… en ratones. Estudios como este demuestran la estrecha relación entre nuestros microbios (la microbiota) y nuestras células. Cuando ese equilibrio se altera y disminuyen el número y diversidad de los microorganismos, tenemos un problema.

As biologist Jeremy Griffith explains in THE Interview (which psychiatrist Professor Harry Prosen described as “the most important interview of all time”), while we humans lacked the explanation for our two-million-year corrupted human condition, we had no choice but to deny that our distant ape ancestors lived in a state of cooperative and loving innocence. But with the good reason for our corrupted condition now finally found, our species’ original state of innocence can at last be admitted.

An artist turned naturalist known for her botanical illustrations, Merian was born just 16 years after Galileo proclaimed that the Earth orbited the sun. But at the age of 50, she sailed from Europe to the New World on a solo scientific expedition to study insect metamorphosis—an unheard-of journey for any naturalist at that time, much less a woman.

Para cada célula humana em nosso organismo, há outras nove impostoras, pegando carona. Você não é formado apenas de carne e osso, sangue e músculo, mas também de bactérias e fungos. Não é um indivíduo, mas uma colônia–um ecossistema. Somos apenas 10% humanos. Até pouco tempo atrás, os micróbios eram vistos como invasores, inimigos, parasitas. Estávamos decididos a exterminá-los. Mas a ciência vem revelando uma história bem diferente: os micro-organismos comandam nosso corpo e evoluíram numa relação de estreita simbiose com os humanos–e é impossível ser saudável sem eles.

Сначала Земля представляла собой негостеприимное чужеродное место: на планету непрерывно обрушивались потоки химических веществ, она была покрыта бурлящими океанами, а ландшафт формировали непрекращающиеся извержения вулканов. Посреди этого буйства стихий и катастроф и началась жизнь. Похожие на мыльные пузырьки первые клетки с дерзкой отвагой бросили вызов безжизненному миру.

Biomimetics literally means emulating biology—and in a broader sense the term covers technological advances where the original inspiration came from nature. The Earth is a vast laboratory where the mechanisms of natural selection have enabled evolutionary solutions to be developed to a wide range of problems. Science writer Brian Clegg looks at how humans have piggybacked on natural experimentation, redeploying a solution to create things that make our lives easier.

For many of us, the great scientific discoveries of the modern age—the Big Bang, evolution, quantum physics, relativity—point to an existence that is bleak, devoid of meaning, pointless. But in The Sacred Depths of Nature, eminent biologist Ursula Goodenough shows us that the scientific world view need not be a source of despair. Indeed, it can be a wellspring of solace and hope. This volume reconciles the modern scientific understanding of reality with our timeless spiritual yearnings for reverence and continuity.

Life innovates constantly, producing perfectly adapted species—but there's a catch. Many animals and plants eke out seemingly unremarkable lives. Passive, constrained, modest, threatened. Then, in a blink of evolutionary time, they flourish spectacularly. Once we start to look, these 'sleeping beauties' crop up everywhere. But why? Looking at the book of life, from apex predators to keystone crops, and informed by his own cutting-edge experiments, renowned scientist Andreas Wagner demonstrates that innovations can come frequently and cheaply to nature, well before they are needed.

Seashells, stretching from the deep past into the present day, are touchstones leading into fascinating realms of the natural world and cutting-edge science.

Throughout the ages, human beings have had a profound fascination with the natural world. It has influenced all aspects of our civilisation, from science and religion to music, art, literature and film. These 12 episodes, taken from Radio 4's epic series Natural Histories, find presenter Brett Westwood exploring two major groups of animals - fish, who have lived on Earth for over 450 million years, and invertebrates, who make up 97 percent of all species worldwide - to find out how our perception and representation of them has changed over time.

Stimmt es, dass Elefanten über ihre Füße hören können? Wie wird CO2 im Ozean abgebaut? Warum sind Bärtierchen gar nicht so groß wie sie klingen? Was haben Farne schon alles überlegen? Warum sind Sukkulenten wahre Spezialisten? Und was haben Gene eigentlich mit einer Schere zu tun? In unserem Podcast beantworten eine marine Mikrobiologin und ein Herpetologe die großen und kleinen Fragen rund um die Biologie der Tiere, Menschen, Pflanzen und allem dazwischen.

This book comes from two authors with scientific backgrounds. It recognizes the huge advances made through science and their beneficial impact on society. However, it also expresses concern that the essentially tentative nature of scientific conclusions is being replaced by a growing tendency to accord to science the last word on a range of subjects.

What is life? Many scientists believe life can be reduced to ‘mechanistic’ factors, such as genes and information codes. Yet there is a growing army of scientists, philosophers and artists who reject this view. The gene metaphor is not only too simplistic but deeply misleading. If there is a way to reduce life to a single principle, that principle must acknowledge the creativity of life, turning genetic determinism on its head.

The egg is a paradox―both alive and not alive―and a symbol as old as culture itself.

Egg is playful, informative, and guarantees that you’ll never take this delicate ovoid for granted again.

Menstruation is something half the world does for a week at a time, for months and years on end, yet it remains largely misunderstood. Scientists once thought of an individual’s period as useless and some doctors still believe it’s unsafe for a menstruating person to swim in the ocean wearing a tampon. Period counters the false theories that have long defined the study of the uterus, exposing the eugenic history of gynecology while providing an intersectional feminist perspective on menstruation science.

A must listen for any animal lover.

Als im späten 16. Jahrhundert der englische Universalgelehrte Robert Hooke und der holländische Tuchhändler Antonie van Leeuwenhoek durch ihre handgefertigten Mikroskope blickten, sahen sie etwas, was der Biologie und der Medizin ein radikal neues Konzept hinzufügte und beide Wissenschaften für immer veränderte: Komplexe lebende Organismen bestehen aus winzigen, in sich geschlossenen und sich selbst regulierenden Einheiten. Unsere Organe, unsere Physiologie, unser Selbst – Herz, Blut, Gehirn – sind aus diesen kleinen Teilen aufgebaut: den Zellen.

This is an inspiring tour of the world's oceans and 80 of its most notable inhabitants. Beautifully illustrated, the book includes fascinating stories of the fish, shellfish and other sea life that have somehow impacted human life - whether in our medicine, culture or folklore - in often surprising and unexpected ways.

As we continue to live through a pandemic, all eyes are on microbes: an imperceptible and pervasive threat that hangs heavy on the air and clings to surfaces. But the reality of micro-organisms is far more diverse and life-sustaining than such a notion would have us believe.
