A world-renowned scientist offers a much-needed analysis of what it takes to have good immune health—helping readers navigate what can really help, what is a complete myth, and why.Does orange juice help ward off colds? And how does our age affect our ability to recover from one? When it comes to immunity, are we really what we eat? Or how much we eat? We are surrounded by big questions and big claims about enhancing our immune systems, so how do we tell the fiction from the facts? And, ultimately, what can we do to reduce our chances of getting sick? World-leading immunologist Daniel M. Davis offers answers in this authoritative, highly accessible, myth-busting guide to the effects of stress, age, exercise, weight, nutrition, sleep, vaccines, and mental health on our immune health. Taking us to the cutting edge of immunology research and explaining both what we know and how we know it, Self-Defense helps readers spot phony claims and make informed choices. Davis shows us that everyone’s immune system is entirely unique, and that’s why we should be wary of one-size-fits-all “cures.” We learn how exercise, for example, has all sorts of different, even opposing, short- and long-term effects on our immune health. And while our gut microbes are vitally important, it’s unlikely that yogurt drinks can really boost your immune system to stop you getting ill. An eye-opening window into some of the astonishing possibilities for the future, when it comes to distinguishing bogus and beneficial health claims about everything from vitamin D to inflammation and cancer therapies, Davis’s book may be your best self-defense.Ver livro
Since the 1960s, Paul Winter has been in the vanguard of musicians whose art expresses special appreciation for the natural music of our world--wolf, whale, wind and water, combined with everything from Bach to Bossa Nova. In this visit Paul tells about the making of Missa Gaia, and his lifelong love affair with music that "presses your wonder button."Ver livro

From the familiar to the improbable, the gross to the endearing, The Modern Bestiary is a compendium of curious creatures. It includes both animals that have made headlines and those you’ve probably never heard of, such as skin-eating caecilians, harp sponges, or zombie worms—also known as bone-eating snot flowers. Arranged by elements, Earth, Water and Air, The Modern Bestiary contains wellknown species told from new and unexpected angles (rats that drive cars; fish that communicate by passing wind), as well as stranger and lesser-known creatures (including carnivorous mice that howl at the moon, cross-dressing cuttlefish, and antechinuses—small marsupials that literally mate themselves to death). Finally, there are the ‘aliens on Earth’—the incredible, the surreal, the magical—such as tardigrades, tongue-eating lice and immortal jellyfish, creatures so astonishing that they make unicorns look rather commonplace. Written by a zoologist with a flair for storytelling, this is a fascinating celebration of the animal kingdom.Ver livro
Theoretical physics is the foundation of our understanding of the universe, providing the mathematical framework that describes physical laws and fundamental interactions. Unlike experimental physics, which relies on observation and experimentation, theoretical physics develops models and equations that predict and explain phenomena, often extending beyond what can currently be tested. From Newton’s laws to Einstein’s theories and quantum mechanics, the field has evolved to encompass a vast range of concepts that shape modern science. Mathematics plays a crucial role in theoretical physics, serving as the language through which physical principles are expressed. Equations such as Newton’s second law, Maxwell’s equations, and Schrödinger’s equation provide precise descriptions of motion, electromagnetism, and quantum mechanics, respectively. The ability to abstractly represent nature through mathematical formalisms allows physicists to derive new predictions and unify disparate concepts. For example, Einstein’s field equations of general relativity describe how mass and energy curve spacetime, leading to predictions of gravitational waves and black holes, both of which were later confirmed through experiments. A key principle in theoretical physics is symmetry, which governs many of the fundamental laws of nature. Symmetries in physical systems often correspond to conservation laws, a relationship formalized by Noether’s theorem. For instance, the symmetry of time invariance leads to the conservation of energy, while spatial symmetry results in the conservation of momentum.Ver livro
