The school health clerk took a comb and pointed to the near-microscopic bugs crawling up and down my daughters' scalps. I cringed. Then she checked my head for the pesky parasites. I held my breath. We had lice. Lots and lots of lice. My youngest daughter scratched her head and started crying. Embarrassed, we headed home. And that began the frustrating, icky, unending, exhausting, humiliating, disgusting battle against the bugs. Parents across the nation are terrified of lice - not because they cause disease, but because even one minuscule egg has the power to keep children out of school and their mothers and fathers out of the office.

The lowly louse may have a more impressive pedigree than once thought: Dinosaurs may have hosted the parasitic bugs, a study says. The findings, published Tuesday in the journal Biology Letters, also show — through comparison of lice — that mammals and birds may have begun to flourish before the dinosaurs went extinct 65 million years ago. That's counter to a long-held idea that they only ascended and diversified once the dinosaurs were gone....

The treatments for head lice aren't pleasant: potentially toxic chemicals, repeated combing for nits, and laundering sheets, clothing and towels. But a Menlo Park dermatologist is urging doctors and parents to try a new cure that he promises is easy and successful. Lice can be cured in 94% of cases by simply soaking the hair and scalp with Cetaphil Gentle Skin Cleanser and then using a hair dryer to dry the cleanser in place, he says.

Using too much Lindane to treat lice infestations can cause deadly brain or nerve damage, federal health officials warned, stressing that the prescription drug should not be used on babies and "with great caution" on children. Once sold in large bottles, Lindane now is to come only in 1- or 2-ounce packets for one-time use, and doctors are told not to prescribe more.

A study of an ancient human pest -- head lice -- suggests that the ancestors of today's American Indians may have met and fought with pre-humans long extinct elsewhere, scientists said Tuesday. Researchers said one type of lice is found worldwide and must have evolved on the ancestors of our species, Homo sapiens. A second type is found, so far, only in the Americas. That type is thought to have come from Homo erectus in Central Asia.

Could lice be the secret to preventing asthma? Research on mice shows that those carrying the most lice had calmer immune systems than uninfested rodents. The finding may have implications for studying the causes of asthma and allergies in people. The study, published in the BioMed Central journal BMC Biology, adds to evidence supporting the so-called hygiene hypothesis, which holds that the rise in asthma and allergies can be linked to hyper-clean living. It was conducted by Joseph Jackson of Britain's University of Nottingham and colleagues, who trapped wild mice and tested the immune systems of those infested or uninfested with the louse Polyplax serrata.
