Dirt for Physical and Mental Health
April 11, 2007
Live Science has an article suggesting that exposure to dirt can improve your mood by boosting the immune system.  This is an unexpected twist on the “hygiene hypothesis” that childhood exposure to dirt and animals helps innoculate the body to certain diseases (see 08/02/2006).  Certain bacteria might not only boost the immune system, but also […]

Questions to Ask a Reductionist Neurobiologist
March 21, 2007
Can the totality of the brain be described in terms of its neurons?  Is consciousness an artifact of the movement of signals in the brain?  Can the complexity of the brain be described in terms of its evolutionary history?  Does the hardware define the software that runs on it? Gy�rgy Buzs�ki attempted to address these questions […]

Have Scientists Found the Secret of Aging?
March 17, 2007
There’s a tragic disease that speeds up aging.  Known as progeria (Huntington-Gilford progeria syndrome, HGPS), it is caused by a single point mutation in exon 11 of the NMLA gene.  Children afflicted with this disease look old beyond their years and often die at 13 of heart attack and stroke – essentially, of old age.

Why Our Voices Are Unique
March 15, 2007
We can usually recognize friends and acquaintances by their voices.  If we all have the same hardware, though, how is this possible?  The answer is in the vortex.  Sounds sci-fi, but researchers at the University of Cincinnati used knowledge of jet engines to explore the possibility that vortices may help solve the mysteries of the […]

Evolutionary Theory Not Even Skin Deep
March 2, 2007
A book on skin just was published – no, not one of those books, but a book on the physiology of human skin.  Nina Jablonski wrote Skin: A Natural History (UC Berkeley, 2006) and Qais Al-Awqati (Columbia U) reviewed it in Science.1  The reviewer noticed that “In its discussion of the human skin, the book’s […]

3 Out of 5 Doctors – Leaves 2
February 28, 2007
Every once in awhile it’s good to be reminded that yesterday’s nutritional advice can be wrong.  We need to beware of simplistic approaches to health.  For instance, the cliches “If a little is good, more is better” or “it worked for me” can be deadly.  TV commercials are filled with glowing promises for this or […]
