AI maps how brain fluids move to clear waste

MR-AIV uses physics-informed AI and DCE-MRI scans to infer 3D brain-wide fluid movement in mice without direct flow measurements. The method distinguished slow diffusion-dominated transport from faster advective flow and estimated pressure and permeability patterns linked to brain waste clearance.

Scientists uncover unexpected thermal retention properties inside the cell

Living cells cool much slower than our current understanding of heat conduction can explain, according to new research from the University of Tokyo. Researchers used two techniques - high-speed temperature mapping and artificial heating - to observe how heat dissipated from living cells and similar-sized artificial, fluid-filled sacs (liposomes).

Research challenges long standing beliefs about cannabis and male hormones

The effects of cannabis on the hormonal system and male fertility remain controversial within the scientific community. A study conducted by the University of Geneva (UNIGE), in collaboration with the Swiss Center for Applied Human Toxicology (SCAHT), provides a new answer by showing that cannabis use does not reduce testosterone levels in young men and may even increase its testicular synthesis.
