Self-Eliminating e-Drive System Reverses Insecticide Resistance in Fruit Flies

Insecticides have been used for centuries to counteract widespread pest damage to valuable food crops. Eventually, over time, beetles, moths, flies and other insects develop genetic mutations that render the insecticide chemicals ineffective.

Chromosome Abnormalities Found in Healthy Women’s Breast Cells

A new study from researchers at The University of Texas MD Anderson Cancer Center finds that, in healthy women, some breast cells that otherwise appear normal may contain chromosome abnormalities typically associated with invasive breast cancer. The findings question conventional thinking on the genetic origins of breast cancer, which could influence early cancer detection methods.

The Role of Macrophages in Shaping the Inflammatory Environment in Rheumatoid Arthritis

Currently there are no cures for rheumatoid arthritis (RA) which affects 40,000 people in Ireland. The disease costs an estimated €20,000 per patient, per year with an overall cost to the health system of ~€544 million. Only 1 in 4 patients achieve remission and a significant proportion of patients have suboptimal responses or no response at all to current available therapies.
