Penis development needs more than just testes and testosterone

Proper development of the fetal penis requires not just testosterone from the testes, but a second hormone produced by other tissues, including the placenta, according to a new study. The results reveal a previously unknown pathway of masculinization of the external genitals.

Hormone therapy may increase cardiovascular risk during gender transition

People receiving hormone therapy during gender transition had an elevated risk for cardiovascular events, such as strokes, blood clots and heart attacks. Findings underscore the importance of counseling and close monitoring of transgender patients receiving hormone therapy.

'Cellular barcoding' reveals how breast cancer spreads

A cutting-edge technique called cellular barcoding has been used to tag, track and pinpoint cells responsible for the spread of breast cancer from the main tumour into the blood and other organs.

Controlling and visualizing receptor signals in neural cells with light

Using a novel optogenetic tool, researchers have successfully controlled, reproduced and visualized serotonin receptor signals in neural cells. To this end, they modified a photosensitive membrane receptor in the eye, namely melanopsin. They were able to switch the receptor on and off using light; it also acted like a sensor indicating via fluorescence if specific signalling pathways in the cell had been activated. The sensor was, moreover, specifically designed to migrate to those domains in the neural cells that are sensitive to the neurotransmitter serotonin.

DDT exposure tied to breast cancer risk for all women through age 54

All women exposed to high levels of DDT are at increased risk for breast cancer through age 54, but the timing of cancer risk depends on when they were first exposed. Women exposed before 14 years of age, particularly in infancy and early childhood, were most likely to develop premenopausal breast cancer, while those who were exposed after infancy were at increased risk of developing cancer later, at 50-54 years of age.
