Memory clinics still rely on visual rating scales to assess brain atrophy, yet these tools lack the sensitivity to catch subtle changes associated with early dementia. A measure of how old a person’s brain appears on brain scans compared with their actual age might be a potential predictor of who is more likely to develop dementia over the years, reports a new study published in Neurology.

An Australian research collaboration has identified several existing TGA-approved medicines that could help slow brain damage in children with a rare form of dementia—offering hope for faster treatment options.

Researchers at the University of Southampton have developed a powerful AI tool that reveals previously invisible patterns inside breast cancers. It uncovers how tiny cellular structures called centrosomes change as tumors grow, spread and evolve. The technology could help clinicians identify high-risk patients, predict how breast cancer might progress and deliver more targeted treatments.

A tumor is more than its cancer cells. Immune cells, blood vessels and other surrounding tissue influence how a cancer grows and responds to treatment. Two tumors containing the same cell types can respond very differently to the same therapy depending on how those cells are arranged. Spatial proteomics captures this organization in molecular detail, but the resulting data, which contain many different variables, are difficult to interpret and compare across studies.

In science, the suffix “phage” means to devour. Thus, the name bacteriophage might conjure images of tiny creatures that “eat” bacteria. While that conception isn’t 100% scientifically accurate, bacteriophages are lethal killers of bacteria nonetheless, and scientists are excited about engineering phage DNA as a path to new antibiotics.
