Wingless (book)
Wingless: A Fairly Weird Fairy Tale is a 2008 children's fairy tale book by Indian author Paro Anand. The book has "equally weird illustrations" in black and white by Atanu Roy.
Plot summary
The story is about a girl called Chutki. She is born wingless, though she's a princess, the much awaited baby of the King and Queen of the Heavens. She is rejected by the angels who are the citizens of the Heavens. Suspense continues when Chutki and her parents find a new home for her on Earth. Chutki's parents now must find her a home which is not too little and nor too big.

Wnt signaling pathway
The Wnt signaling pathways are a group of signal transduction pathways made of proteins that pass signals into a cell through cell surface receptors. Three Wnt signaling pathways have been characterized: the canonical Wnt pathway, the noncanonical planar cell polarity pathway and the noncanonical Wnt/calcium pathway. All three pathways are activated by binding a Wnt-protein ligand to a Frizzled family receptor, which passes the biological signal to the protein dishevelled inside the cell. The canonical Wnt pathway leads to regulation of gene transcription. The noncanonical planar cell polarity pathway regulates the cytoskeleton that is responsible for the shape of the cell. The noncanonical Wnt/calcium pathway regulates calcium inside the cell. Wnt signaling pathways use either nearby cell-cell communication (paracrine) or same-cell communication (autocrine). They are highly evolutionarily conserved in animals, which means they are similar across animal species from fruit flies to humans.
Book
A book is a set of written, printed, illustrated, or blank sheets, made of ink, paper, parchment, or other materials, fastened together to hinge at one side. A single sheet within a book is a leaf, and each side of a leaf is a page. A set of text-filled or illustrated pages produced in electronic format is known as an electronic book, or e-book.
Books may also refer to works of literature, or a main division of such a work. In library and information science, a book is called a monograph, to distinguish it from serial periodicals such as magazines, journals or newspapers. The body of all written works including books is literature. In novels and sometimes other types of books (for example, biographies), a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, and so on). An avid reader of books is a bibliophile or colloquially, bookworm.
A shop where books are bought and sold is a bookshop or bookstore. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 unique titles had been published. In some wealthier nations, printed books are giving way to the usage of electronic or e-books, though sales of e-books declined in the first half of 2015.
Book (graph theory)
In graph theory, a book graph (often written 
) may be any of several kinds of graph.
One kind, which may be called a quadrilateral book, consists of p quadrilaterals sharing a common edge (known as the "spine" or "base" of the book). A book of this type is the Cartesian product of a star and K2 .
A second type, which might be called a triangular book, is the complete tripartite graph K1,1,p. It is a graph consisting of 
triangles sharing a common edge. A book of this type is a split graph.
This graph has also been called a 
.
Given a graph 
, one may write 
for the largest book (of the kind being considered) contained within .
The term "book-graph" has been employed for other uses. Barioli used it to mean a graph composed of a number of arbitrary subgraphs having two vertices in common. (Barioli did not write for his book-graph.)
