...several thousand dollars (Krtolica declined to provide an exact figure, citing ongoing talks with a few IVF clinics). There scientists thaw and nurture the embryos to generate stem cells. These are then removed, cultured and allowed to grow. The surviving colonies are then frozen and kept cryopreserved in liquid nitrogen in StemLifeLine's own freezers on the premises. (The company charges about $350 per year to keep the cells in deep freeze...
...removing about 800,000 of Beijing’s nearly three million vehicles from the road during the conference—and pushing people to make greater use of busses and subways—officials cut the city’s concentration of a certain type of harmful nitrogen oxide by 40 percent.

...Fireflies and Phosphorescent Seas: How and Why Animals Produce Light.” The conference also featured experiments performed live, which taught the children about basic reactions through demonstrations such as “Baking Soda and Vinegar: A Chemical Reaction” and “Liquid Nitrogen Ice Cream.” One of the undergraduate volunteers running the ice cream experiment asked the young members in the audience, “Anyone know what liquid nitrogen is made of?” leading one of the students to eagerly reply, “nitrogen...
