Australian researchers have identified a previously overlooked population of immune cells in the skin that physically restrain melanoma growth by engulfing live melanoma cells, and the discovery could reshape thinking around macrophage-targeted cancer therapies and innate immunity in oncology.

WAVES, an algorithm designed to extract menstrual-cycle metrics from physiological signals such as basal body temperature, which oscillates with sex hormones, shows how different parameters change with age and helps determine whether each person maintains a stable individual pattern or personal footprint. A study based on data from 5,674 cycles from 753 women demonstrates through this tool that age is associated with higher temperatures, shorter cycles, and greater irregularity. In addition, several metrics show within-person stability, suggesting they could serve as personalized health markers.

Minimal residual disease (MRD) has become a central concept in modern oncology, reshaping how clinicians evaluate response, relapse risk and treatment precision. As increasingly sensitive technologies reveal traces of cancer that persist after therapy, MRD is emerging as both a biological challenge and a clinical opportunity, especially as new data illuminate its complexity across hematologic and solid tumors. This topic was addressed at the 2026 American Association for Cancer Research (AACR) annual meeting.

At BioEurope Spring 2026, pharma representatives and investors shared their thoughts about current and future landscapes of different disease areas, and on how to move toward success – both at the level of individual companies and for indications as a whole.

HORMA domain-containing protein 1 (HORMAD1) is a protein that promotes meiotic recombination and its expression is usually restricted to germ-line cells, although it has been shown to be actively expressed out of context in about 60% of triple-negative breast cancers (TNBCs). A team at The Institute of Cancer Research has found that this aberrant expression in tumor cells perturbs mitotic arrest and generates aneuploidy, leading to a weakening of the spindle assembly checkpoint and in kinetochore-microtubule error correction.

There is broad agreement that psychiatric diagnoses in their current form are not reflective of any underlying biology, and that this is one of the things hampering psychiatric drug development. “We are still fully reliant on descriptive diagnoses that yield heterogeneous patient cohorts,” Steve Hyman told the audience at the European Congress of Neuropsychopharmacology (ECNP) Roadmap Meeting on Precision Psychiatry in Amsterdam in January.

Parkinson’s disease is a neurodegenerative disorder that affects movement, and tremor is one of its signatures. But it is a much more wide-ranging disorder, and patients experience problems with cognitive and emotional processes as well. SCAN, the somato-cognitive action network identified in 2023, could reshape the definition of PD. Treating this circuit can improve outcomes.
