_{Depression and obesity are major global health burdens, yet the co-occurrence patterns and temporal trends of their comorbidity remain poorly characterised at the global level. To map the global patterns of co-occurring depression and obesity, quantify temporal trends of depression, obesity and comorbidity, forecast the prevalence of comorbidity up to 2035 and compare social indicators across groups stratified by their combined temporal trends of depression and obesity.}

Researchers have identified seven proteins in the blood that could enable better blood tests for Alzheimer’s disease. A study shows that using a broader panel of markers provides a clearer picture of the disease and allows for more accurate future treatment choices.

Researchers at the University of Leicester are looking for 450 people willing to ditch meat in 2026 as they explore how vegetarian and vegan diets can affect our long‑term health.

Research has long shown that exercise benefits both physical and mental health. Now a new study from researchers at BYU suggests that it may also strengthen marriages, especially when couples exercise together.

The study, recently published in Family Relations, found that couples who participated in shared physical activity reported better communication, stronger conflict resolution and lower levels of marital stress than couples who did not exercise together.

Bacteria naturally release microscopic particles known as bacterial extracellular vesicles. This review considers how these vesicles could be adapted for precision cancer medicine, from carrying drugs and activating immune responses to limiting metastasis and identifying cancer biomarkers. It also examines the practical obstacles ahead, including inconsistent production, safety risks, contamination and the lack of shared manufacturing and quality standards.

L'Oréal Groupe and NUS Medicine integrate skin, scalp and hair health into longevity research

Medical devices for point-of-care diagnosis need to be small and fast. Researchers from TMOS have designed and built a first-of-its-kind optical surface for developing ultracompact devices that can image transparent samples, such as cells. Their new device reduces the need for large supporting components by embedding multiple functions in a single surface and selecting them externally using the wavelength and polarisation of light illuminating a sample. This new approach presents a novel design philosophy in nanophotonics.

In a new Nature study published on August 10, 2026, Scripps Research scientists developed Dyna-1, a machine learning (ML) model that can predict protein dynamics on the micro-to-millisecond timescale. In seconds, Dyna-1 identifies regions of proteins likely to undergo these movements, revealing aspects of protein function that have remained hidden from conventional computational approaches. Because these micro-to-millisecond dynamics are particularly conserved across biology since they control function, mapping them could help researchers uncover new connections between protein movement and human health.
