Scientists Crack 200-Year 'Dolomite Problem' in the Lab
Researchers from the University of Michigan and Hokkaido University have grown dolomite in the laboratory for the first time, solving a 200-year-old geological puzzle. The mineral's growth normally stalls because calcium and magnesium atoms lodge in wrong positions, creating defects that block further crystal formation. By pulsing an electron beam 4,000 times over two hours, the team dissolved these defects and grew approximately 100 nanometers of dolomite, far surpassing the previous record of five layers. The breakthrough could reshape how high-tech materials are manufactured.

Moringa Seeds Found to Remove 98% of Microplastics From Water
Brazilian researchers discovered that moringa seeds can pull microplastics from drinking water with over 98% efficiency, rivaling conventional chemical treatments. The seeds contain proteins that act as natural coagulants, binding to negatively charged microplastic particles and causing them to clump together for easy filtration. In alkaline conditions, the plant-based treatment outperformed standard synthetic chemicals. The study, published in ACS Omega, highlights moringa as a biodegradable, low-cost alternative viable for regions lacking advanced water infrastructure.

Amino Acid Cocktail Boosts mRNA Therapy 20-Fold
Researchers found that co-administering three common amino acids with lipid nanoparticles can boost mRNA delivery up to 20-fold and push CRISPR gene editing efficiency from around 25% to nearly 90% in a single dose. The optimized cocktail of methionine, arginine, and serine enhances a cellular pathway that helps nanoparticles enter cells more efficiently. In mice with acute liver failure, survival rose from 33% with standard treatment to 100% when the amino acid supplement was added. The study was published in Science Translational Medicine.

World's River Deltas Sinking Faster Than Seas Are Rising
A comprehensive Nature study found that 18 of 40 major river deltas worldwide are subsiding faster than local sea levels are rising, putting more than 236 million people at increased flood risk. Human activities including groundwater pumping, reduced sediment flow, and rapid urbanization are driving the problem, with groundwater extraction the dominant factor in 35% of deltas studied. Subsidence rates range from under one millimeter per year in Canada's Fraser River Delta to over one centimeter per year in China's Yellow River Delta. Major deltas of the Mekong, Nile, Ganges-Brahmaputra, and Mississippi rivers are among those most affected.

Vitamin B7 Reveals Hidden Weakness in Cancer Cells
Researchers at the University of Lausanne discovered that vitamin B7 acts as a metabolic "license" enabling cancer cells to bypass their dependence on glutamine by activating the enzyme pyruvate carboxylase. When biotin is unavailable, the enzyme stops functioning and cancer cell growth halts. The study also found that mutations in the FBXW7 gene, common in many cancers, eliminate this backup pathway and lock cells into glutamine dependence. The findings, published in Molecular Cell, explain why many therapies targeting glutamine addiction in tumors have failed.
