Book Description
The beautifully written story of shells and their makers, and our relationships with them. Seashells are the sculpted homes of a remarkable group of animals: the molluscs. These are some of the most ancient and successful animals on the planet. But watch out. Some molluscs can kill you if you eat them. Some will kill you if you stand too close. That hasn't stopped people using shells in many ways over thousands of years. They became the first jewelry and oldest currencies; they've been used as potent symbols of sex and death, prestige and war, not to mention a nutritious (and tasty) source of food. Spirals in Time is an exuberant aquatic romp, revealing amazing tales of these undersea marvels. Helen Scales leads us on a journey into their realm, as she goes in search of everything from snails that 'fly' underwater on tiny wings to octopuses accused of stealing shells and giant mussels with golden beards that were supposedly the source of Jason's golden fleece, and learns how shells have been exchanged for human lives, tapped for mind-bending drugs and inspired advances in medical technology. Weaving through these stories are the remarkable animals that build them, creatures with fascinating tales to tell, a myriad of spiralling shells following just a few simple rules of mathematics and evolution. Shells are also bellwethers of our impact on the natural world. Some species have been overfished, others poisoned by polluted seas; perhaps most worryingly of all, molluscs are expected to fall victim to ocean acidification, a side-effect of climate change that may soon cause shells to simply melt away. But rather than dwelling on what we risk losing, Spirals in Time urges you to ponder how seashells can reconnect us with nature, and heal the rift between ourselves and the living world.

Book Description
This book presents a method for replicating natural butterfly wing scales using a variety of metals for state-of-the-art applications requiring high surface-enhancement properties. During the past decade, three dimensional (3D) sub-micrometer structures have attracted considerable attention for optical applications. These 3D subwavelength metallic structures are, however, difficult to prepare. By contrast, the 3D superstructures of butterfly wing scales, with more than 175 000 morphologies, are efficiently engineered by nature. Natural butterfly wing scales feature 3D sub-micrometer structures that are superior to many human designs in terms of structural complexity, reproducibility, and cost. Such natural wealth offers a versatile chemical route via the replication of these structures into functional metals. A single versatile chemical route can be used to produce butterfly scales in seven different metals. These synthesized structures have the potential for catalytic (Au, Pt, Pd), thermal (Ag, Au, Cu), electrical (Au, Cu, Ag), magnetic (Co, Ni), and optical (Au, Ag, Cu) applications. Plasmon-active Au, Cu, Ag butterfly scales have exhibited excellent properties in surface-enhanced Raman scattering (SERS). The Au scales as SERS substrates have ten times the analyte detection sensitivity and are one-tenth the cost of their human-designed commercial counterparts (KlariteTM). Preliminary mechanisms of these surface-enhancement phenomena are also reviewed.

Book Description
In this “deeply personal and lyrical book” (Publishers Weekly) from the New York Times bestselling author of The Horse, Wendy Williams explores the lives of one of the world’s most resilient creatures—the butterfly—shedding light on the role that they play in our ecosystem and in our human lives. “[A] glorious and exuberant celebration of these biological flying machines…Williams takes us on a humorous and beautifully crafted journey” (The Washington Post). From butterfly gardens to zoo exhibits, these “flying flowers” are one of the few insects we’ve encouraged to infiltrate our lives. Yet, what has drawn us to these creatures in the first place? And what are their lives really like? In this “entertaining look at ‘the world’s favorite insect’” (Booklist, starred review), New York Times bestselling author and science journalist Wendy Williams reveals the inner lives of these delicate creatures, who are far more intelligent and tougher than we give them credit for. Monarch butterflies migrate thousands of miles each year from Canada to Mexico. Other species have learned how to fool ants into taking care of them. Butterflies’ scales are inspiring researchers to create new life-saving medical technology. Williams takes readers to butterfly habitats across the globe and introduces us to not only various species, but “digs deeply into the lives of both butterflies and [the] scientists” (Science magazine) who have spent decades studying them. Coupled with years of research and knowledge gained from experts in the field, this accessible “butterfly biography” explores the ancient partnership between these special creatures and humans, and why they continue to fascinate us today. “Informative, thought-provoking,” (BookPage, starred review) and extremely profound, The Language of Butterflies is a “fascinating book [that] will be of interest to anyone who has ever admired a butterfly, and anyone who cares about preserving these stunning creatures” (Library Journal).

Book Description
When it comes to color, nothing can surpass the vast palette found in nature, from a bright green leaf in a sun-dappled forest to the rich red feathers of a cardinal. Nature's Portraits offers sixty detailed drawings that can be brought brilliantly to life with nothing more than a few colored pencils or crayons and a sense of wonder about the world around us. Each illustration is captioned with the common and Latin names of the species pictured.

Book Description
"Koji Owens is the new kid...again. As the only son of an Air Force F-16 pilot, he's learned to adapt and survive every time they move. It's not easy starting over with new friends and schools every two years, but when the Owens family makes their final move to New York, Koji finally has hope for a normal high school life--that is, until he finds a strange bracelet in his locker. Transformed into a storm-summoning dragon warrior, Koji finds himself caught up in a world of ancient powers, secret identities, and colossal monsters threatening to destroy his new home. But these awesome powers come with strings attached, and revealing his true identity could mean losing everything he loves. With his family and friends now in mortal danger and New York City in flames, Koji must find the courage to become the hero they need and face down an enemy hiding in plain sight."--Back cover.
