Under certain conditions, it takes less time to cool a hot system than to cool the same system initiated at a lower temperature. This phenomenon – the “Mpemba Effect”, has been observed in a variety of systems, including water, magnetic alloys and carbon nano-tube resonators. So far, no single generic mechanism to explain this counter-intuitive behavior was suggested. Using the theoretical framework of nonequilibrium thermodynamics, we construct a minimal model that describes this behavior and… Read more about Special Kavli/AM Seminar
The Kavli Koffee hour is a weekly meeting that aims to bring together experimentalists and theorists from around Harvard to discuss current research. Unlike usual seminars, speakers are required to talk about something that… Read more about Kavli Koffee Hour

Christopher A. Walsh, M.D., Ph.D. Chief, Division of Genetics and Genomics, Children's Hospital Boston Investigator, Howard Hughes Medical Institute Bullard Professor, Pediatrics and Neurology, Harvard Medical School As soon as the fertilized egg divides for the first time, the genomes of cells start accumulating spontaneous mutations, due to errors in DNA replication or other causes. In principle, every cell in the body has its own distinct genome defined by spontaneous mutations. Though… Read more about One brain, many genomes: genomic variability between single neurons in health and disease

In the wild, microbial rhodopsin proteins convert sunlight into biochemical signals in their host organisms. Some microbial rhodopsins convert sunlight into changes in membrane voltage. We engineered a microbial rhodopsin to run in reverse: to convert changes in membrane voltage into optical signals that are readily detected in a microscope. These proteins have very strong optical nonlinearities, enabling new approaches to… Read more about Engineering Proteins for Bidirectional Neuro-optical Interfaces

Dr. Silvia Vignolini Melville Laboratory for Polymer Synthesis, Department of Chemistry, University of Cambridge Lensfield Road, Cambridge CB2 1EW, UK Nature’s most vivid colours are produced when light repeatedly scatters against periodically organized interfaces within nanostructured materials. This brilliant iridescent colouration is frequently used in many insect and animals but also in different species of plants. One of the most striking example is… Read more about Cellulose Photonics: from nature to applications
