The discussion of differences between the female and male brain has long been a subject of debate, extending well beyond the neuroscience community. Yet, the question of whether these differences exist at all is often treated as settled. Recent research suggests that even such fundamental metrics as sex-based differences in overall brain volume become negligible once corrected for body size. Scientists behind a recent paper published in Science decided to probe the question further: at the...

Breast cancer is the most common malignancy among women, and its brain metastases carry the most unpredictable and often fatal outcomes. The challenge of treating this particular metastasis lies not only in the need to cross the blood-brain barrier to deliver drugs: until recently, scientists did not even understand the mechanism by which cancer cells migrate from breast tissue to the brain, nor why cancer cells target it in the first place given that the microenvironment differs...
