Gamma-Ray Bursts: The Biggest Explosions Since the Big Bang | Harvard Department of Physics

by Harvard University 4,895 views

Representing nature's biggest explosions since the Big Bang itself, gamma-ray bursts were first accidentally spotted in the 1960s by Department of Defense satellites hunting for terrestrial nuclear blasts. In this talk Prof. Berger describes the ensuing decades-long quest to decipher the origin and energy source of these mysterious explosions. He explains how gamma-ray bursts are now used to probe the first generation of stars and galaxies formed less than a billion years after the Big Bang.

Connectomics: Mapping the Brain | Harvard Department of Physics

by Harvard University 3,162 views

Despite intense interest in the ways brains work, we still have quite a rudimentary understanding of this organ, especially compared to our knowledge of the other organ systems in the body. One central problem is that brain function is based on a much more complicated cellular organization than found in any other part of the body. The brain contains billions of nerve cells and these are interconnected by trillions of synapses in a vast wiring diagram. This wiring diagram has not been described but likely contains the physical instantiations of all the brain does including all the memories we hold and all the skills we have learned. In addition such a wiring diagram may be disrupted when there are abnormalities in brain function such as learning disorders in children or psychiatric diseases in adults. In this lecture, Prof. Lichtman discusses how scientists are taking the first steps in imaging and understanding the wiring diagram of the brain.

Robotic insects make first controlled flight

by Harvard University 693,702 views

The demonstration of the first controlled flight of an insect-sized robot is the culmination of more than a decade's work, led by researchers at the Harvard School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering at Harvard. Half the size of a paperclip, weighing less than a tenth of a gram, the robot was inspired by the biology of a fly, with submillimeter-scale anatomy and two wafer-thin wings that flap almost invisibly, 120 times per second.

"This book provides a comprehensive, self-contained introduction to one
of the most exciting frontiers in astrophysics today: the quest to
understand how the oldest and most distant galaxies in our universe
first formed. Until now, most research on this question has been
theoretical, but the next few years will bring about a new generation of
large telescopes that promise to supply a flood of data about the infant
universe during its first billion years after the big bang. This book
bridges the gap between theory and observation. It is an invaluable
reference for students and researchers on early galaxies."

Molecular Motor Struts Like Drunken Sailor

by Harvard Medical School 23,235 views

Molecular motors, built from proteins, are a kind of transport service that keep us functioning by trafficking essential chemical packages throughout the cell. To understand how molecular motors work, some researchers are creating animations. Here, each "leg" of a molecular motor called dynein moves as it progresses along a cellular structure called a microtubule. New data—collected by a team led by Samara Reck-Peterson and published online Jan. 8, 2012, in "Nature Structural & Molecular Biology"—suggest that dynein's walk is even stranger than the one modeled.

From Biopolymer Translocation to Hemodynamics: New Challenges in Multiscale Computing

by Harvard University 588 views

Multiscale modeling is the capability of representing different levels of phenomena, occurring at diverse spatial and temporal scales, within a unified conceptual framework. A typical example is the behavior of long molecules or nanosuspensions under the action of complex hydrodynamic flows. Our computational work tackles different phenomena such as biopolymer translocation through nanopores and hemodynamics in arteries with a novel computational scheme. The solution of such large-scale problems calls for the exploitation of powerful parallel architectures, such as the Blue Gene supercomputer, and sophisticated visualization tools to gain insight into the realm of multi-scale phenomena.

Medical Imaging Computing: From Data to Understanding

by Harvard University 4,934 views

The development of new technologies that acquire large amounts of complex data is accelerating throughout medicine. Corresponding breakthroughs in accessible computation and algorithm development have made image analysis an indispensable tool for medical research and clinical practice. For example, image analysis enables the data acquired using diffusion tensor imaging (DTI) and functional magnetic resonance (fMRI) to reveal subject-specific structure and function of the brain.

The emerging field of medical image computing requires strong, interdisciplinary teams of researchers, physicians, and engineers. Building such teams is a challenge but ultimately rewarding process. The Surgical Planning Lab at Brigham and Women's Hospital was founded in 1990 to enable research in image computation within the hospital context. Today, the SPL is the hub of the National Alliance for Medical Image Computing, a national effort with international impact across biomedicine and, increasingly, other fields of science. NAMIC drives scientific and engineering innovation through interdisciplinary collaboration, application-driven development, a well-designed hardware and software infrastructure, and an open-source approach to dissemination and community building.

This presentation will describe how research ideas evolve into useful medical and scientific tools within the SPL and NAMIC environments.

An Introduction to Computational Multiphysics: Motivations for Triple-M Modeling

by Harvard University 3,131 views

Modern science is increasingly faced with problems of ever greater complexity, straddling across the traditional disciplinary boundaries between physics, chemistry, material science and biology. Computational science is responding to this challenge with a steadfast development of innovative modeling techniques, designed in such a way as to offer an optimal handling of the information transfer procedures connecting the different scales/levels involved in the quantitative description of the aforementioned complex phenomena. This entails the seamless coupling between different mathematical representations of various physical phenomena at widely disparate scales, from continuum fields to probability distribution functions and atomistic trajectories, all the way down to many-body quantum wave functions. In this series of lectures, we shall provide an introduction to the basic ideas behind these triple-M (multiscale/multiphysics/multilevel) techniques, together with the illustration of a few practical examples, drawn from concrete applications in leading areas of multiphysics research, such as micro/nanofluidics, turbulence and material science.

Books to Bench to Bedside Informatics for Autism Research

by Harvard University 2,447 views

May 31, 2006 - Isaac Kohane, Lawrence J. Henderson Associate Professor of Pediatrics and Health Sciences and Technology; Associate Professor of Medicine, HMS/Children's Hospital

Autism Spectrum Disorder (ASD) is a socio-cognitive disorder which has a high (up to 1% by some estimates) prevalence in our society. More controversially, ASD is reported to be on the increase. Less controversially, ASD is known to have a strong inherited component as well as an environmental component. And yet, despite decades of research, precious little is understood about the causes of this disorder and existing therapies are often unsatisfactory. Notwithstanding, the genomic revolution offers the potential for some novel insights and therapies. The seminar will review the challenges and the solutions that computational approaches bring to a systematic understanding of ASD. The integrative role of computing in synthesizing insights from the genome, bibliome, imaging and other measurement modalities is reviewed and a broader role for computing in the investigation of complex diseases is proposed.
