A novel radioguided surgery technique could quickly and effectively identify residual cancer cells during brain tumor surgery, with low radiation exposure for both patients and surgeons. The study reports that Y-90 DOTATOC, a beta-minus-emitting tracer, can effectively delineate the margins of meningiomas and high-grade gliomas.

The detection and imaging of protein-protein interactions in live cells just got a lot more colorful, thanks to a new technology. The new method converts biochemical processes into color changes that are easily visualized. This method is a new tool for cell biologists and neuroscientists to use to address questions ranging from fundamental mechanisms in cell biology, to the underlying causes of mental illness, to the discovery of novel therapeutics.

Female sex hormones have a strong effect on the psyche. This has been confirmed by numerous scientific studies and by phenomena such as the "baby blues", a bout of low mood following childbirth, or recurrent mood swings that occur prior to menstruation. However the male sex hormone testosterone also affects our mood and emotions, as well as our libido - and in a positive way.
