A University of Cambridge study found that brain activity in people with compulsive sexual behavior is similar to that triggered by drugs in the brains of drug addicts. The ventral striatum, dorsal anterior cingulate, and amygdala regions were more active in individuals with compulsive sexual behavior compared to healthy volunteers.
Researchers developed a simple setup for X-ray phase-contrast imaging, which uses scrambled X-rays to produce high-quality images. The new technique demonstrates efficiency and versatility, enabling accurate measurement of specimen thickness and mapping of small structures.
The device allows researchers to study chemical reactions in liquid water under pressure without it freezing into a solid. High-pressure measurements shed light on calcium ions and may impact hydraulic fracturing and nuclear waste behavior.
