I read your article about bilirubin protecting cells from free radicals and possibly cancer and heart disease. People with Gilbert’s syndrome, which affects 5 percent of the population, have higher-than-normal amounts of bilirubin in their blood. Has any study been conducted to ascertain whether people with Gilbert’s syndrome have a lower incidence of cancer and […]

Icicle waves go with the flow
A new model of icicle growth may explain the strange fact that ripples often found on those icy spikes typically sit about 1 centimeter apart, whether the icicles themselves are big or small.

“Waves,” or crenulations, occur not only on water icicles, but also in caves on dripstone and flowstone speleothems composed of calcite, epsomite, goethite, and even mud. All of these formations display “wavelengths” of around 1 centimeter. The origin of these crenulations is due not to heat, but to greater evaporation and carbon dioxide loss from […]

An alternate approach to Parkinson’s
While levodopa is the treatment of choice for Parkinson's disease, drugs called dopamine agonists, which mimic the neurotransmitter dopamine, may work as well early in the disease, cause fewer side effects, and preserve levodopa's effectiveness.
