AUSTIN, Texas — Seed size is controlled by small RNA molecules inherited from a plant’s mother, a discovery from scientists at The University of Texas at Austin that has implications for agriculture and understanding plant evolution.
“Crop seeds provide nearly 70 to 80 percent of calories and 60 to 70 percent of all proteins consumed by the human population,” said Z. Jeff Chen, the D.J. Sibley Centennial Professor in Plant Molecular Genetics at The University of Texas at Austin. “Seed production is obviously very important for agriculture and plant evolution.” (more…)
*Berkeley Lab Researchers Resolve Sub-nanometer Structure of Cascade, an Ally for Human Immune System*
A complex of proteins in the bacterium E.coli that plays a critical role in defending the microbe from viruses and other invaders has been discovered to have the shape of a seahorse by researchers with the U.S Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). This discovery holds far more implications for your own health than you might think.
In its never-ending battle to protect you from infections by bacteria, viruses, toxins and other invasive elements, your immune system has an important ally – many allies in fact. By the time you reach adulthood, some 90-percent of the cells in your body are microbial. These microbes – collectively known as the microbiome – play a critical role in preserving the health of their human host. (more…)
