Editor’s Selections: Eggs, Flimsy houses, Summer spending, and Fingerprints

Featured this week in my ResearchBlogging.org column: At Powered by Osteons, Kristina Killgrove has a fantastic seasonal post up on the symbolism of eggs and their role in burials. At Gambler’s House, teofilo clears up usage of the word “flimsy” in the context of Mississippian houses by highlighting an interesting bias that the word contributes. [...]

Baby Mice Born from Eggs Made from Stem Cells

mouse egg stem cell babies

Stem cells have been coaxed into creating everything from liver cells to beating heart tissue. Recently, these versatile cells were even used to make fertile mouse sperm, suggesting that stem cell technology might eventually be able to play a role in the treatment of human infertility. Now two types of stem cells have been turned [...]

Sperm face steep odds when set free to fertilize an egg. A slightly faulty tail, a miscalibrated electrical charge on their cell membrane or some other subtle defect can keep these genetic couriers from becoming the lucky, lone swimmer that sires offspring. And now it seems that a surprisingly common genetic mutation might decrease a [...]

Sperm cells’ swimming secrets revealed

sperm swim molecular channel

The predictable swimming sperm featured in health class videos are rather uncharacteristic portraits of the life of these sex cells. Spermatozoa actually spend most of their time resting up in the male reproductive tract so they can make a dash to the egg once the opportunity arises. It has long been known that the little [...]
