- Male sex hormone loss aids brain tumour growth
Depletion of male sex hormones aids brain tumour growth by inducing neuroinflammation and disrupting hormonal signalling and immune responses. This discovery was published in Nature on May 6, 2026. The findings suggest a link between male sex hormone loss and brain tumour development.
- Brain tissue near tumours is loaded with plastic
A study published in Nature on April 24, 2026, found high levels of micro- and nanoplastics in brain tissue near tumours, suggesting a potential breakdown of the blood–brain barrier. The discovery highlights possible environmental health risks and links plastic contamination to neurological conditions.
