A new joint study from Constructor University and Princeton University in the Journal of the American Chemical Society focuses on PC645, a protein complex that contributes to cryptophyte algae’s ability to photosynthesize efficiently using specialized light-harvesting pigments that can capture energy from dim, blue-green underwater light. During photosynthesis, the pH inside the algae can fluctuate significantly, affecting how they manage light energy.

Sugar molecule could help protect against dangerous hospital fungus Candida auris
Researchers have developed a potential new approach against the highly drug-resistant hospital fungus Candida auris. They discovered that a synthetic sugar molecule that is a natural part of the fungus's cell wall, but is not present in humans, could underpin a future vaccine, develop protective antibodies and form the basis of a prototype rapid diagnostic test.

An open-source tool for automated consolidation of lipid data
In collaboration with the University of Vienna, the Technical University of Munich (TUM), and Heidelberg University, researchers at the TUD Dresden University of Technology have developed an innovative tool that significantly simplifies lipid research. The new open-source platform, LipidLibrarian, enables the automated consolidation of fragmented data from international lipid databases, such as LIPID MAPS, SwissLipids, and ALEX123, into a single, user-friendly interface for the first time. This enables researchers to identify new diagnostic markers more quickly, and to develop personalized therapies and innovative medicines. A study published in the Journal of Lipid Research details the platform's functionality and potential
Sugar swap simplifies production of promising targeted cancer therapies
Researchers at the University of Wisconsin–Madison have developed a simpler way to produce a fast-growing class of targeted cancer therapies, a discovery that could make the medicines easier to manufacture consistently while driving the development of new treatment options.
Fertilizer made from local rocks could help feed hungry in Africa
Food insecurity is a major problem in many parts of the world, particularly Africa, where more than 300 million people regularly go hungry. Now, using the Canadian Light Source (CLS) at the University of Saskatchewan, researchers from Morocco have developed a way to produce fertilizer from local African rocks, which could make it easier for farmers to grow the crops needed to feed local residents.
