La actual pandemia de COVID-19 es como un agujero negro de incertidumbre e inseguridad. Vivimos en una situación de excepción y por las grietas del miedo nos cuelan informaciones, a menudo sin mala intención, que pueden ser muy perjudiciales para la población. Es por ello que debemos armarnos con nuestro mejor recurso, la evidencia científica.

Antoine Lavoisier reinvented chemistry, overthrowing the long-established principles of alchemy and inventing an entirely new terminology, one still in use by chemists. Madison Smartt Bell’s enthralling narrative comes across like a race to the finish line, as the very circumstances that enabled Lavoisier to secure his reputation as the father of modern chemistry—a considerable fortune and social connections with the likes of Benjamin Franklin—also caused his glory to be cut short by the French Revolution.

Edwin Grosvenor writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada. He also examines Bell's humanitarian efforts, including support for women's suffrage, civil rights, and speeches about what he warned would be a "greenhouse effect" of pollution causing global warming.

Until the early 1870s, very little was known about the creatures lurking in the depths of our oceans. The first systematic investigation into life in our oceans was made during the circumnavigation of the HMS Challenger. Scientists credit this voyage as the beginning of modern oceanography. In this book, Graham Bell takes listeners through the voyage station by station, following the progress of the expedition and introducing some of the new and strange animals that were hauled up from the depths of the ocean and seen by human eyes for the first time.

"La persona intelligente è una persona che ha fatto in un campo molto ristretto tutti i possibili errori". Niels Bohr. La voce di Gabriella Greison, fisica, scrittrice e attrice teatrale, racconta in maniera semplice la fisica quantistica, facendo un percorso suggestivo tra le menti che l'hanno creata e le loro geniali intuizioni. La fisica quantistica è nata dall'incrocio dei pensieri dei cervelli più grandi della scienza del XX secolo, e Gabriella Greison traccia questo sentiero fatto anche di slanci emotivi e colpi di scena, di litigi e di lunghe riflessioni.

Les grands drames vécus lors d'une guerre relèguent habituellement les événements moins tragiques, au second rang. Bien que ces derniers passent inaperçus durant les combats, ils ne méritent pas moins d'être connus du public à cause du sentiment de bienveillance, de compassion, d'amour et d'innombrables preuves d'humanité dont ils ont fait preuve. Ce livre audio ne s'attarde donc pas sur les protagonistes des grandes batailles.

La pétrifiante pandémie a fait des milliers de victimes dans le monde entier. Elle restera gravée dans nos mémoires comme un tournant de l'Histoire.

Pendant cette douloureuse épreuve, d'innombrables gestes de fraternité, d'humanité et de bonté ont réussi à irradier nos cœurs en peine en nous apportant du secours tendre, doux, souriant.

After years of prosecuting hard-core criminals, rising legal star Alan Bell took a private sector job in South Florida's newest skyscraper. Suddenly, he suffered such bizarre medical symptoms, doctors suspected he'd been poisoned by the Mafia. Bell's rapidly declining health forced him to flee his glamorous Miami life to a sterile "bubble" in the remote Arizona desert.

Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we've learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes.

In Vera Rubin: A Life, Jacqueline Mitton and Simon Mitton provide a detailed, accessible overview of Rubin's work, showing how she leveraged immense curiosity, profound intelligence, and novel technologies to help transform our understanding of the cosmos. But Rubin's impact was not limited to her contributions to scientific knowledge. She also helped to transform scientific practice by promoting the careers of women researchers. Not content to be an inspiration, Rubin was a mentor and champion for hiring women faculty and honoring them with awards historically exclusive to men.

Conraad de Rosner is a pioneering game ranger, working with dogs to protect wildlife against poachers – both ‘bushmeat’ poachers, who use cruel snares to trap animals, and criminal syndicates killing for rhinoceros horn and capturing critically endangered pangolins, the most trafficked animal in the world. Con’s life – constantly at risk from poachers, wildlife and even his own fellow rangers – has been saved on numerous occasions by his devoted canine companions.

It was not easy being a woman of ambition in early 20th-century England, much less one who wished to be a scientist. Cecilia Payne-Gaposchkin overcame prodigious obstacles to become a woman of many firsts: the first to receive a PhD in astronomy from Radcliffe College, the first promoted to full professor at Harvard, the first to head a department there. And, in what has been called "the most brilliant PhD thesis ever written in astronomy", she was the first to describe what stars are made of.

Fred Rogers was an international celebrity, a pioneer in children's television, an advocate for families, and a multimedia artist and performer. He wrote the television scripts and music, performed puppetry, sang, hosted, and directed Mister Rogers' Neighborhood for more than thirty years. The Green Mister Rogers centers on the show's environmentalism. Ultimately, Rogers cultivates a practical wisdom that provides a way for children to confront the environmental crisis through action and hope and, in doing so, develop into adults with greater care for the environment.

La notte stellata non è solo uno spettacolo affascinante, ma lo spazio sterminato nel quale sono scritte migliaia di scoperte scientifiche e di antiche storie. I nostri antenati hanno trovato nel cielo le conoscenze più utili alla sopravvivenza: hanno imparato a orientarsi in mare o nei deserti, a costruire orologi e calendari, a sfruttare i cicli stagionali per i lavori dei campi. Incantati dai movimenti degli astri e dei pianeti, intimoriti dalle eclissi o dalle comete, hanno anche popolato il firmamento di dèi ed eroi che ne spiegassero il mistero.

Crystal Fire is a tale of the human factors in technology; the pride and jealousies coupled with scientific and economic aspiration that led to the creation of modern microelectronics and ignited the greatest technological explosion in history.

Si sa che la scienza in Italia suscita molti sospetti. E questi sospetti non vanno disgiunti da una certa ignoranza in materia, che fa dell'Italia una pecora nera in Europa. Così capita che parliamo correntemente di Ogm (organismi geneticamente modificati), ma senza sapere cosa siano i geni e in cosa gli Ogm siano diversi da una qualunque coltivazione; ci preoccupiamo dei vaccini, ma senza sapere nulla di come funzionino e di quante malattie abbiano contribuito a eradicare.
