Our food and our bodies are full of tiny protein fragments called peptides. These small chains of amino acids act as biological messengers, influencing processes ranging from sensory perception to physiological functions.

Indian millets contain distinct lipid fingerprints with anti-diabetic and anti-inflammatory potential
Indian millets are a staple for the country's population of more than a billion. They are also gaining global popularity, with rising exports and a reputation as a climate-resilient crop. Now, new research shows that their nutritional value includes a rich diversity of lipids, including a previously undetected group that may offer potential health benefits. The research is published in the journal Food Chemistry.

Bacteria reveal 'glue' protein that fastens antibiotic-resistant outer membrane to cell wall
Researchers at the University of Notre Dame and collaborators have discovered a key process in how the outer membrane of gram-negative bacteria attaches to the cell wall, advancing the understanding of how these bacteria frequently develop resistance to antibiotics.
Beyond frozen snapshots, protein 'breathing' comes into view with combined imaging methods
Advances in structural biology have allowed scientists to determine molecular structures with atomic-level detail, sometimes yielding static snapshots that do not reflect the dynamism of proteins. However, these motions are often crucial for biological function. Researchers from the Institute of Science and Technology Austria (ISTA), together with international collaborators, have now combined several methods to shed light on how proteins "breathe" and how some experimental techniques freeze their motion. The findings—which could boost protein design approaches and improve AI-based structural prediction tools—are published in Nature Chemistry.
New hybrid materials separate rare earths without harsh chemicals
Rare earth elements (REEs) are essential for everyday technologies such as smartphones, LED lights, wind turbines and many medical applications. At the same time, supply chains are under pressure because of the geographic concentration of production, and electronic waste is growing worldwide.
