Seed germination is controlled by several plant hormones, which are researched intensely. However, not much was known about the processes that need to take place to allow the hormones to function.  Since the tests are for vaccines that can save millions of animals, protect farmers' livelihoods and alleviate hunger, Beer said they were "justified".  Sperm are influenced by diet, and the effects arise rapidly. This is the conclusion of a study by researchers at Linköping University, in which healthy young men were fed a diet rich in sugar.  Researchers analyzed semen from 49 men whose partners had lost three or more consecutive pregnancies before the 20-week mark.  Single-molecule fluorescent measurements provide fresh insights into a process for keeping errors out of our genomes.  Histones are proteins that regulate the unwinding of DNA in the cell nucleus and the expression of genes based on chemical modifications or "marks" that are placed on their tails.  Now, in a new paper published in Nature Structural & Molecular Biology, Mayo researchers have determined how one DNA repair protein gets to the site of DNA damage.  A microscopic thread of DNA evidence in a public genealogy database led California authorities to declare this spring they had caught the Golden State Killer, the rapist and murderer who had eluded authorities for decades.  Researchers at Delft University of Technology, in collaboration with colleagues at the Autonomous University of Madrid, have created an artificial DNA blueprint for the replication of DNA in a cell-like structure.  An LMU team now reveals the inner workings of a molecular motor made of proteins which packs and unpacks DNA.  Chemist Ivan Huc finds the inspiration for his work in the molecular principles that underlie biological systems.
