If not for a virus, none of us would ever be born.
In 2000, a team of Boston scientists discovered a peculiar gene in the human genome. It encoded a protein made only by cells in the placenta. They called it syncytin.
The cells that made syncytin were located only where the placenta made contact with the uterus. They fuse together to create a single cellular layer, called the syncytiotrophoblast, which is essential to a fetus for drawing nutrients from its mother. The scientists discovered that in order to fuse together, the cells must first make syncytin.
What made syncytin peculiar was that it was not a human gene. It bore all the hallmarks of a gene from a virus.

If you are curious about the world–about its galaxies, its clouds, its quarks, its crickets–then you probably own at least a few books about science. Or you have a lot. The book–by which I mean bound sheets of paper marked by moveable type–is one of the best devices for storing and retrieving information about science. It is also the kind of device we can fall in love with. On my own shelves, I have new books that are bringing me up to date on genome biology and dark matter, as well as dinged-up old books, such as a paperback edition of The Origin of Species, Stephen Jay Gould’s The Panda’s Thumb, and The Encyclopedia of Plagues and Pestilence. We dip back into old books, or reread them in full, and they thus keep us company through our time on this planet.
