If you plan on slicing a finger or scraping a knee anytime soon, try to make it during the day. Scientists report that the time of day when you're injured may impact healing rate, based upon the circadian rhythms of skin cells.
Looking at a database of persons recovering from burn wounds, they found that people injured during the day took 17 days to heal compared to 28 days on average for those injured at night.
As if being obese wasn't enough of a health risk, new research suggests that fat cells can absorb at least one chemotherapy drug used to treat several forms of leukemia, reducing the efficacy of treatment. Fat cells also appear to change the drug's molecular structure so it's less toxic to leukemia cells.
The study was the first to show fat cells metabolize and inactivate a therapeutic drug.

"One of the signs of an approaching nervous breakdown is the belief that one's work is terribly important."
--British philosopher Bertrand Russell (1872-1970), whose work did prove to be terribly important but who died at the age of 98 from influenza
This week in 1952, a dense smog descended upon London, England that would last four days, causing at least 4,000 deaths and transportation chaos as visibility was reduced to a few hundred yards. Freshening winds and a rise in temperature eventually dissipated the fog. Most deaths occurred among the elderly, the very young or those with medical problems. The primary cause of the smog was pervasive coal burning.

Poinsettias have a greatly exaggerated reputation for being toxic. There has never been a confirmed death attributed to consuming poinsettia leaves (the gaudy red foliage is actually colored bracts or modified leaves; the real flowers are small and yellow) in humans and the plant is only mildly toxic to some pets. Eating the leaves may produce vomiting, drooling and diarrhea, but usually only in the most severe cases.
"Is it not meningitis?"
--American novelist Louisa May Alcott (1832-1888). The writer of "Little Women" and its sequels, Alcott had suffered chronic ill health for many years. She did not have meningitis, but may have died from mercury poisoning, the consequence of an earlier treatment for typhoid fever.
