Researchers from the University of Geneva and Lausanne University Hospital report they have visualized, in three dimensions and under near-native conditions, how cytotoxic T cells organize their killing machinery at the immune synapse. The work, published in Cell Reports, applies cryo-expansion microscopy to human T cells and to tumor tissue samples, providing nanoscale views intended to support immunology and cancer research.

Researchers at MIT have found that young mice exposed to the carcinogen NDMA develop significantly more DNA damage and cancer than adult mice, despite equal exposure levels. The study highlights how rapid cell division in juveniles amplifies risks from the chemical, present in contaminated water, medications, and processed foods. Findings urge changes in safety testing to include younger animals.

Researchers at Fred Hutch Cancer Center have created human-like monoclonal antibodies that prevent Epstein-Barr virus (EBV) from infecting immune cells. Using mice engineered with human antibody genes, the team identified antibodies targeting viral proteins gp350 and gp42, with one fully blocking infection in lab models. The findings, published in Cell Reports Medicine, could lead to therapies for transplant patients at risk of EBV-related complications.

Following Comptroller General approval and publication in the Official Gazette, the nationwide oncology sanitary alert—declared by President José Antonio Kast in late March amid delays affecting thousands on cancer waiting lists—has taken effect. It grants the Ministry of Health extraordinary powers to expedite diagnostics and treatments for 33,000 patients until September 30, 2026, with potential extension.

Researchers in Brazil report that an artificial-saliva formulation made with a lab-modified sugarcane protein, CaneCPI-5 (also written CANECPI-5), can bind to tooth enamel and help reduce bacterial activity and mineral loss in laboratory experiments designed to model the severe dental risks faced by head and neck cancer patients after radiotherapy. The work, published in the Journal of Dentistry, found the formulation performed best when combined with fluoride and xylitol.

Researchers at Oregon Health & Science University have identified hidden fluid flows inside cells that rapidly transport proteins to the leading edge, challenging traditional views of cellular movement. The discovery, made during a classroom experiment, could explain why some cancer cells spread aggressively. The findings appear in Nature Communications.
