Students break new ground in understanding genetic diversity of bacteriophages Over the last seven years, thousands of undergraduate students have sequenced and analyzed the genomes of bacteria-infecting viruses, known as bacteriophages. Those genomes are now the focal point of a new study that examined the genetic diversity of 627 phages isolated from a single species of bacteria. The study shows
Facts about our microbial menagerie Trillions of microorganisms inhabit us -- inside and out. Scientists are surveying these microbial metropolises to learn more about their role in health. Here are a few details of what researchers have learned so far
New material for creating artificial blood vessels Blocked blood vessels can quickly become dangerous. It is often necessary to replace a blood vessel – either by another vessel taken from the body or even by artificial vascular prostheses. Researchers have developed artificial blood vessels made from a special elastomer material,. Over time, these artificial blood vessels are replaced by endogenous material a natural, fully functional vessel is once again. The method has already been used successfullyChallenging work tasks may have an upside for the brain Professionals whose jobs require more speaking, developing strategies, conflict resolution and managerial tasks may experience better protection against memory and thinking decline in old age than their co-workers.
