Researchers unravel DNA tangles and enzyme seamstresses
Almost three metres of tightly-coiled DNA strands fit into a cell's nucleus. As DNA replicates, the strands unwind and unfold and then re-package into chromosomes, the genetic blueprints of life ?but what happens if this process becomes entangled? Untangling the heaps of DNA strings during cell division is the job of special enzymes called topoisomerases. How they achieve this feat may be...A protein complex that untangles DNA
Every second, the cells constituting our bodies are replaced through cell division. Researchers at Karolinska Institutet have found a piece of the puzzle of how genetic information remains intact despite this continuous exchange of cells. Their results are presented in the latest issue of the scientific journal Molecular Cell. An adult human consists of about 50,000 billion cells, 1% of w...Salk scientists untangle steroid hormone signaling in plants
When given extra shots of the plant steroid brassinolide, plants "pump up" like major league baseball players do on steroids. Tracing brassinolide's signal deep into the cell's nucleus, researchers at the Salk Institute for Biological Studies have unraveled how the growth-boosting hormone accomplishes its job at the molecular level. The Salk researchers, led by Joanne Chory, a professor i...Corning brand cover glass rectangles, 0.16 to 0.19mm thick from Sigma-Aldrich

A Research was conducted by Kenneth Norman, Sean Polyn and Jonathan Cohen (Neuroscientists) for studying mental time travel. It was funded by the National Institute of Health. It is the way in which people// relate back to various events that has occurred in the past. This could help in knowing about their mental state. The research is of great importance in the field on psychology an...1-Meter Roll-Up Tangent Screen

Description:The Laserex Tango ophthalmic laser system provides two lasers in the one system: an SLT laser and a photodisruptor for posterior capsulotomy and iridotomy. The SLT laser is a frequency-doubled Nd:YAG producing pulsed 532 nm light. The photodisruptor laser is an Nd:YAG producing 1064 nm. The appropriate laser can be easily selected and treatment by both lasers is channelled through the same delive...
