Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers from ƻ����Ժ discovered that while changing temperatures and rainfall had little impact on the crocodiles’ gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.</p> Mon, 23 Jan 2023 16:26:04 +0000 shirley.cardenas@mcgill.ca 288646 at /newsroom /newsroom/channels/news/using-dna-strands-design-new-polymer-materials-283461 <p>ƻ����Ժ researchers have chemically imprinted polymer particles with DNA strands – a technique that could lead to new materials for applications ranging from biomedicine to the promising field of “soft robotics.”</p> <p>In a study published in <em>Nature Chemistry</em>, the researchers describe a method to create asymmetrical polymer particles that bind together in a spatially defined manner, the way that atoms come together to make molecules.</p> Mon, 18 Dec 2017 21:56:12 +0000 christopher.chipello@mcgill.ca 32803 at /newsroom /newsroom/channels/news/dna-cages-may-aid-drug-delivery-230159 <p>Nanoscale “cages” made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, ƻ����Ժ researchers report in a new study. </p> <p>The research, published online Sept. 1 in Nature Chemistry, marks a step toward the use of biological nanostructures to deliver drugs to diseased cells in patients.
