Drosophila is one of the most thoroughly studied lab animals -- with the exception of the female reproductive tract. Now a team of biologists has taken the first deep look at the Drosophila uterus and found some surprises, which could have implications not just for understanding insect reproduction and potentially, pest control, but also for understanding fertility in humans.

Research shows that the breast cancer gene 1 (BRCA1) not only pushes accurate DNA repair to guard against cancer but promotes subsequent activity in tumor suppression.

For all its pervasiveness and the efforts to study it, cancer is still somewhat of a mystery. Why do some animals get it at a higher rate than others? This is the question at the heart of Peto's paradox, the observation that large animals, by virtue of their number of cells, are statistically more likely than smaller animals to develop and accumulate genetic mutations that lead to cancer, yet they don't. In fact, some large animals, including whales and elephants, get much less cancer than expected for an animal of its body size and number of cells.

Researchers have successfully developed an ultra-sensitive pressure sensor for electronic skin modeled after the nervous system in the human brain. This technology is applicable to future devices, including AI-based digital healthcare devices, and is expected to be utilized across various fields, such as transparent displays and wearable devices, due to its transparency and physical flexibility.
