Whether we watch quick little songbirds at our backyard feeders, keep a flock of chickens, teach parrots to talk, or stand looking up at the sky, mesmerized by the aerial acrobatics of blackbirds gathering as the leaves turn in the fall, humans have an almost universal admiration of and interest in birds. We love the birdsong of spring, the fledglings in summer, the deep V of geese in autumn, the bright spot of red cardinals against white snow. Wild or domestic, birds are clearly one of God's best gifts. This collection of forty heartwarming true stories of our fine feathered friends from animal-lover Callie Smith Grant celebrates that gift. With stories of brave budgie brothers, serene shore birds, hungry hummingbirds, a curious crow, an owl that came into a boy's life as an answer to prayer, and many more, Consider the Birds is the perfect companion to a cozy blanket, a cup of tea, and a chair by the window—where you can see the birds.Ver livro
Enzymes are essential biological molecules that drive the chemical reactions necessary for life. These specialized proteins act as catalysts, accelerating biochemical reactions without being consumed in the process. Without enzymes, many of the reactions that sustain life would occur too slowly to support cellular function, metabolism, and overall biological activity. Their role is fundamental to everything from digestion and energy production to DNA replication and cellular communication. One of the most crucial functions of enzymes is their ability to facilitate metabolic processes. Enzymes lower the activation energy required for reactions, making it possible for cells to convert nutrients into usable energy efficiently. For instance, the enzyme amylase breaks down carbohydrates into simple sugars, while proteases and lipases help digest proteins and fats, respectively. Without these enzymes, organisms would struggle to extract energy from food, leading to a breakdown in normal physiological functions. Beyond metabolism, enzymes play a key role in DNA replication and repair. DNA polymerase, for example, ensures the accurate copying of genetic material during cell division, while ligases and helicases assist in maintaining the stability and integrity of DNA strands. These enzymatic activities are vital for growth, reproduction, and the prevention of genetic mutations that could lead to diseases. Enzymes also regulate gene expression by modifying DNA and histones, controlling which genes are turned on or off in response to environmental or developmental signals.Ver livro

Every system — natural or human — has a breaking point. Ice sheets collapse, forests burn, markets crash, societies fracture. Now, as the planet edges toward a cascade of irreversible shifts, humanity faces its own moment of balance. In Tipping Points, Alex Southwick examines the fragile thresholds that define our age — from the melting Arctic permafrost to the strain on global food networks and the fraying bonds of political trust. Drawing on science, history, and on-the-ground reporting, Southwick reveals how these crises intertwine, amplifying one another into a single planetary reckoning. Yet this is also a story of resilience. Across the world, communities, cities, and movements are learning to adapt — not by returning to the old normal, but by building something entirely new. Sweeping in scope yet intimate in its insight, Tipping Points is a profound exploration of how climate chaos doesn’t just threaten civilization — it’s already redefining what civilization means.Ver livro
