Cisplatin is a chemotherapy drug given to more than half of all cancer patients. The drug kills cells very effectively, but tumors can become resistant to the drug and grow back. A new study offers a possible way to overcome that resistance.
Earlier this year, a 17-year-old French woman arrived at her ophthalmologist with pain and redness in her left eye. She had been using tap water to dilute the cleaning solution for her contact lenses, and even though they were meant to be replaced every month, she would wear them for three. As a result, the fluid in her contact lens case had become contaminated with three species of bacteria, an amoeba calledAcanthamoeba polyphaga that can caused inflamed eyes.
The mystery of the woman’s inflamed eyes was solved, but Bernard La Scolaand Christelle Desnues looked inside the amoeba, they found more surprises.
Everyone grows older, but scientists don't really understand why. Now, a new study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process.
