11.5 billion years old: Stellar archaeology traces Milky Way's history
(Phys.org) -- Unfortunately, stars don't have birth certificates. So, astronomers have a tough time figuring out their ages. Knowing a star's age is critical for understanding how our Milky Way galaxy built ...

Stem cells' 'suspended' state preserved by key step, scientists report
Scientists have identified a gene that is essential for embryonic stem cells to maintain their all-purpose, pluripotent state. Exploiting the finding may lead to a greater understanding of how cells acquire their specialized ...

Cell microenvironments hold key to future stem cell therapies
Adult stem cells and their more committed kin, progenitor cells, are prized by medical researchers for their ability to produce different types of specialized cells. The potential of using these cells to repair ...

Skeletons point to Columbus voyage for syphilis origins
Skeletons don't lie. But sometimes they may mislead, as in the case of bones that reputedly showed evidence of syphilis in Europe and other parts of the Old World before Christopher Columbus made his historic voyage in 1492.
