Viral nano electronics
Article Abstract:
Angela M. Belcher learned about the M13 phage, a long, skinny virus that parasitizes bacteria but is harmless to humans in the mid-1990s. She was the first in demonstrating that the virus could also tag and manipulate inorganic molecules, such as the metals and semiconductors that are located at the heart of so many useful products.

Math without words: Numerical reasoning seems independent of language
Article Abstract:
The brain is not compartmentalized the way 19th--century phrenology maps showed, but it does process math and language abilities in different areas. It is speculated that the brain may build its mathematical understanding with language and that the structure may still stand after the scaffolding is removed.

Half-brained schemes
Article Abstract:
Evidence suggests that people born without a callosum benefit from enhanced development of subsidiary bridges between the brain hemispheres. It was found that halving the brain of an epileptic child suppresses debilitating seizures without interfering with the development of normal intellectual abilities.
