Eucalyptus bark, usually stripped from logs and treated as waste, could be repurposed to help clean polluted water, filter dirty air and capture carbon dioxide, according to new research from RMIT University.

Researchers at RMIT have shown the bark can be converted into a highly porous form of carbon that traps pollutants as water or air flows through it. The findings point to a practical way of turning a common forestry by‑product into a useful environmental material using a relatively simple processing method.

For the first time, MIT researchers measured the dynamics of chromatin movement over an extended period of time, ranging from the scale of microseconds to hours. The findings offer insight into how gene expression is regulated, as well as how chromatin segments come together for other processes such as DNA repair.

"Ultra-Processed Food and Health: From Mechanisms to Actions” brought together many of the world’s leading experts to examine one of the most pressing topics in nutrition science.

The symposium convened an international group of researchers, clinicians and policy experts to explore the rapidly evolving science surrounding ultra-processed foods and their impact on human health. Discussions spanned the biological mechanisms linking ultra-processed foods to chronic disease, the gaps in available research, the role of the food environment and industry practices, and opportunities for policy and public health action.
