With stem cells so fickle and indecisive that they make Shakespeare’s Hamlet pale by comparison, scientists today described an advance in encouraging stem cells to make decisions about their fate. The technology for doing so, reported here at the 242nd National Meeting & Exposition of the American Chemical Society (ACS), is an advance toward using stem cells in “regenerative medicine” — to grow from scratch organs for transplants and tissues for treating diseases.
Using a modern version of open-wide-and-keep-this-under-your-tongue, scientists today reported taking the temperature of individual cells in the human body, and finding for the first time that temperatures inside do not adhere to the familiar 98.6 degree Fahrenheit norm. They presented the research at the 242nd National Meeting & Exposition of the American Chemical Society (ACS), being held here this week.

The road to a Nobel Prize began for one scientist in elementary school when his father placed a sign on his bedroom door proclaiming him to be a “doctor.” For another Nobel laureate, it was a childhood breakfast with the famous scientist (and Nobelist) Linus Pauling. Another noted researcher went against all expectations of her day to pursue science in school, even though she was a woman. Yet another took inspiration from a yellow sweater knitted by his mother.
In a finding that could help fight terrorism and improve safety in laboratories working with explosive chemicals, scientists are reporting development of a new material made of nanoparticles that can quickly detect and neutralize explosives.
