Breast cancer remains a significant challenge, particularly in aggressive forms like triple-negative breast cancer (TNBC). This is a type of breast cancer where the tumour cells lack hormonal receptors, like estrogen receptors. This means that common breast cancer treatments targeting these receptors are not effective against TNBC, making it more challenging to treat and prone to spreading. Scientists are constantly searching for new ways to target the underlying mechanisms that allow these cancer cells to grow and spread unchecked.

Sex determination in animals is an interesting topic. While the X and Y chromosomes decide the sex of an unborn baby in humans and most other mammals, external factors like temperature and humidity decide it for the crocodiles and turtles. But what decides the sex of a young zebrafish? Research now shows that a combination of internal and external factors play a role in determining sex in zebrafish. Understanding the process in depth can throw light on some of the intricate workings of nature, say the researchers.
