10 Oldest Known Diseases


In the study of ancient diseases, nothing speaks like the dead.  So it's relatively easy to date tuberculosis due to the lesions it leaves on bones. Pneumonia may be more ancient than TB, but lung tissue doesn't hold up so well after being buried. DNA testing of samples from mummies and skeletons can conclusively identify disease. And even without the evidence of a body, genes in existing samples of TB and leprosy bacteria suggest prehistoric origin.

This week, a look at the 10 oldest known diseases.

Every Night You Lose More Than A Pound While You Sleep

Why do we weigh less in the morning?  This article suggest is it carbon loss.  Maybe it is water vapor, maybe it is something else entirely like running in your dreams.  Then again, may it is magic.  

Two of the many comments attached to this article: "now if i can just figure out how to sleep 30 days in a row" and "to sleep: perchance to diet".

This week, a look at losing weight through sleep.
