Squeeze the egg in your palm using an even pressure. Next, put your thumb and index finger on the ends of the egg and squeeze.

With more than 500 sperm banks in the United States and tens of thousands of donors, it was bound to happen. As reported Friday in the Journal of Pediatrics, a sperm donor from Michigan passed on a rare and potentially deadly genetic disorder to five children.The disorder, called severe congenital neutropenia, affects only one in five million newborns. Those with the disorder lack a certain type of white blood cell, and this leaves them vulnerable to a host of infections and also leukemia. Fortunately medication, albeit at $200 a day, can keep white blood cell counts high.Doctors thought it was more than a coincidence when five kids born to four couples in the Detroit area were discovered with congenital neutropenia. They traced it back to one sperm bank and one man.For now this seems to be an honest mistake. The donor, known but unnamed in the report, could have been an asymptomatic carrier of the disease. (The only problem is that his whereabouts … [Read more...] about The Good, the Bad and the Ugly Sperm
Emily Gould (pictured right) is 1/2 of Emily Books and the author of an essay collection, And The Heart Says Whatever . She was previously an Associate Editor at Hyperion Books, and an Editor at Gawker . Tell me a little bit about what Emily Books is, and what your aim is with it. Emily Books is a new kind of bookstore, a book-club / bookstore hybrid that selects one book each month to sell and discuss, then publish essays about (or inspired by) that book on our website. You can subscribe and get our pick automatically each month – we email the file for you to download to your phone or ereader or computer – or you can buy books a la carte. All the books we’ve selected so far have been independently published and a few of them have not been previously available as ebooks. We pick books that we believe deserve a big readership they didn’t reach on their original publication. It’s a slightly weird thing to do, but it seems to be working. We’re basically saying: "These are … [Read more...] about 5 Minutes on The Verge: Emily Gould
Brazilian supermodel Gisele Bundchen's recent comments that all women should be required by law to breastfeed have sparked a heated debate about the benefits of breastfeeding newborns over using formula. Most new mothers in the United States breastfeed their children , as 75 percent of mothers report having breastfed at some point. About 43 percent choose to continue breastfeeding for six months, and 22 percent continue until the infant is 12 months old, according to data from the 2007 National Immunization Survey released by the Centers for Disease Control and Prevention. There are several reasons why a mother may choose to bottle-feed her baby instead, as breastfeeding and formula both pose their own unique challenges and conveniences. Why would a mother choose to bottle-feed? Bottle-feeding can allow new mothers to be less restrictive with their diets, as they might be concerned that the food and medication that they ingest can be passed along to their babies through … [Read more...] about Why Would Moms Not Want to Breastfeed?
