Feel the force: new 'smart' polymer glows brighter when stretched

Researchers created a stress-detecting polymer by incorporating copper complexes into polybutylacrylate, shining brighter when stretched. The copper complexes emit light at greater intensity, enabling the detection of small amounts of stress.

Researchers uncover the genomics of health

Researchers have compiled a genome reference database of thousands of healthy older Australians, providing a powerful framework to identify new disease-causing gene variants. The database shows genetic changes associated with ageing, including shorter telomeres and less mitochondrial DNA, which may predict health outcomes for individuals.

Teens with obesity and PCOS have more 'unhealthy' bacteria

Research published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism found that teens with obesity and PCOS have an altered gut microbiome compared to those without the condition. This altered microbiome is associated with higher testosterone levels, metabolic complications, and other health risks.

Preventing metastasis by stopping cancer cells from making fat

Cancer cells store lipids in vesicles called lipid droplets, making them more invasive and prone to forming metastases. The researchers found that TGF-beta2 is the switch responsible for both lipid storage and aggressive cancer cell behavior.
