Mysterious Chromosome Structure

Image
In High School, We’re taught that in the nucleus of every cell, DNA molecules are tightly packed around proteins called  Histones  to form our Chromosomes .  But New research has found that there’s a whole lot more to chromosomes than the   25,000 or so Genes  they contain -  Scientists found that Mysterious Sheath-Like Structure   accounts for up to 47 percent of every Chromosome.  For more than a Century, our understanding of Chromosomes has been based on the assumption that they’re made from a complex of DNA and Histone proteins called C hromatin , formed within the Nucleus of each cell.  Since their discovery in 1882, Chromosomes have been the subject of intense study, but the details of their internal structure have eluded us, in no small part because Chromosomes are completely invisible in the Cell’s Nucleus - unless the Cell is dividing. When a cell divides via Meiosis or Mitosis , the Chromatin inside becomes more tightly packed, causing the chromosomes to bec

New Solution in The Fight Against Superbugs

New Light-Activated Nanoparticles Kill Over 90% of Antibiotic-Resistant Bacteria Bacterial Resistance to Antibiotics is a growing Problem around the World, Responsible for Some 2 Million Infections in the US each year that lead to approximately 23,000 Deaths. But a new Nanoparticle Treatment developed by Researchers at the University of Colorado Boulder could provide an effective means of Fighting Antibiotic-Resistant Bacteria including Salmonella , E. coli , and Staphylococcus, based on Results in a Laboratory Environment. In testing with a Lab-Grown Culture, The Nanoparticles killed 92 Percent of Drug-Resistant Bacterial Cells while leaving the other Cells intact. The treatment consists of Light-Activated Nanoparticles called  Quantum Dots. These extremely Small Particles, Which resemble the Semiconductors used in Electronics, are about 20,000 Times smaller than a Human Hair, and when excited by Light they prove deadly to Drug-Resistant Bacterial Cells.

Communication via Brain

Image
For the First time, An international team of  Neuroscientists  has Transmitted a Message from the  Brain  of One Person to Another.     The team, which includes researchers from Harvard Medical School’s Beth Israel Deaconess Medical Center, the Star lab Barcelona in Spain, and Axilum Robotics in France, has announced today the successful transmission of a brain-to-brain message over a distance of 8,000 kilometers. "We wanted to find out if one could communicate directly between two people by reading out the brain activity from one person and injecting brain activity into the second person, and do so across great physical distances by leveraging existing communication pathways,” said one of the team,  Harvard’s Alvaro Pascual-Leone in a press release.  "One such pathway is, of course, the Internet, so our question became, 'Could we develop an experiment that would bypass the talking or typing part of internet and establish direct brain-to-brain communicat
