Nanoscale Bouquet of Flowers

June 7th 2013

About 25 micrometers wide and 100 micrometers tall these "flowers," created by scientists at Harvard, are made from barium carbonate and silica. Through a complex chemical process, the researchers can induce these tiny flower-like structures to self-assemble. By controlling the environmental temperature different shapes and sizes can be coaxed to spontaneously form.

This method of manufacturing nano-scale structures has implications for the nano-industry in the long run. But for now, I would really love to order a custom made nano-bouquet for my girlfriend, accompanied by a false color image, as the bouquet would be next to invisible to the naked eye.

Should men be able to give birth to children?


Lisa Mandemaker: Using an artificial womb could lead to more equality between sexes, but also between different family layouts. If men would be able to give birth to children, it would maybe be easier for male same-sex couples to have a child together.
