Showing results for "BANG BANG" in Biology

A journey through life, the universe and everything. From what actually happened in the big bang to the accidental discovery of Post-it notes, science is packed with surprising discoveries. Did you know, for instance, that if you were to get too close to a black hole it would suck you up like a noodle (it's called spaghettification), why your keyboard is laid out in QWERTY (it's not to make it easier to type) or whether the invention of the wheel was less important to civilisation than the bag (think about it)? New Scientist does.

Do you ever find yourself wondering how we came to exist? Or how humans came to call planet Earth our home? Oxford Professor Tim Coulson uncovers the history of the entire universe from the Big Bang to human existence taking listeners of all backgrounds on a journey that covers physics, chemistry, biology, the evolution of consciousness, through to the rise of humanity. A 13.77-billion-year epic in the making, A Universal History of Me encapsulates for the general listener everything that he as a scientist has wanted to find out about life, the universe and everything in between.

Every one of us contains a billion times more atoms than all the grains of sand in the earth’s deserts. If you weigh 150 pounds, you’ve got enough carbon to make 25 pounds of charcoal, enough salt to fill a saltshaker, enough chlorine to disinfect several backyard swimming pools, and enough iron to forge a 3-inch nail. But how did these elements combine to make us human?

For Irwin Shapiro, science starts with questions. This book provides a broad and entertaining survey of major scientific discoveries that have changed our views of nature and, in turn, spawned further questions. Shapiro, an award-winning scientist and beloved teacher, separates his inquiry into three parts: looking up at the universe; looking down at the earth and its fossils; and looking in at the story of life. His framework encourages listeners to view science as a detective story—to observe and question nature and natural phenomena, and to base all conclusions on scientific evidence.

Quando e dove è iniziata la vita? E a cosa somigliavano le prime forme di vita? Interrogativi che l'uomo si pone da sempre, per i quali, pur in mancanza di risposte definitive, si possono avanzare alcune ipotesi. Come quella che colloca l'origine della vita intorno a 3,8 miliardi di anni fa, in un contesto riconducibile a uno di questi ambienti: brodo primordiale, campi geotermali, siti di impatto meteoritico. Certo è che le tessere del più grande e affascinante dei puzzle restano RNA, amminoacidi, protogeni, protocellule.

Dieses Hörbuch macht die komplexe Entstehung des Lebens auf unserem Planeten erstmals für alle verständlich. Dabei stand das Leben auf der Erde schon mehrfach kurz vor der Auslöschung. Es gab zwei Millionen Jahre dauernde Vulkanausbrüche und mehrfach schwere Asteroideneinschläge. Katastrophen, ohne die allerdings etwa die Ausbreitung der Säugetiere nicht möglich gewesen wäre. Henry Gee schildert unterhaltsam und anschaulich, wie sich das Leben immer wieder durchsetzte.

Viren, Bakterien, Parasiten: Mittlerweile geistern zum Thema Corona so viele Begrifflichkeiten umher, dass es Zeit wird, in einem kleinen Leitfaden etwas Ordnung zu schaffen. Kurz, sachlich und unterhaltsam erklärt Dr. med. Caroline Neumann, welche Erregertypen es gibt, wie sie übertragen werden, ob und wie sie dem Menschen schaden können - und natürlich, wie man sich vor ihnen schützen kann. Natürlich kommt dem Corona-Virus besondere Aufmerksamkeit zu. Dieser kompakte Leitfaden ordnet die Fakten, wie sie uns im Sommer 2020 zur Verfügung stehen.
