Diego Ramirez, Class Of 2012 created this Mitosis Flipbook Project for Biology Class. He had to include names of phases of mitosis with explanation/description of changes in process of cell division and make the animation ( digital or on paper) smooth and understandable. Great job!

Jeannie’s work is creating highly-adopted technology and practices through facilitating user-centered design research and development at the intersection of technical and field disciplines. Her biology research background inspires her successful unique approach to technological problems ranging from: disaster management (Carnegie Mellon Silicon Valley, Disaster Management Initiative), interface/software design for outdoor environments and data processing (BioACT), Human Computer Interaction Group, InfoLab at the Stanford Computer Science Department) to facilitating cost-effective civil engineering designs for multi-million dollar infrastructure projects (Delta Risk Management Strategy, California Department of Water Resources). Recently, she organized CrisisCampSiliconValley March 26-28, 2010, NASA Ames Research Park, which generated requirements and grant-writing teams for improved disaster response in the Bay Area. Jeannie is a Visiting Scientist in the Carnegie Mellon Silicon Valley CyMobility Lab Disaster Management Initiative (NASA Ames Research Park, Moffett Field, CA) and Senior Biologist at the civil engineering firm, URS Corporation, Oakland CA. Her awards cross computer science and biology disciplines and include Random Hacks of Kindness hack-a-thon (Tweak the Tweet — Twitter syntax modifying behavior to get increased and parsable data from the ground), IEEE-ACM Vannevar Bush Best Student Paper, and an NSF Doctoral Dissertation Grant. Jeannie received her PhD …

Functional Genomics At DNA And RNA Level: We know that for a large number of organisms a complete genome sequence is now available, so in functional genomics by the help of genomic sequence we can excess every single gene to study and evaluate its function at systemic level Transcriptomics: Functional genomics sequences that are based on DNA sequencing and are used to study mRNA expression profiles on a biological scale are known as transcriptomics. The expression profile of a gene can reveal a lot about its functional role in the cell and can also help to identify functional links to other genes. For example, the expression of many genes is restricted to specific cells or developing structures, often showing that these genes have particular functions in those places other genes are expressed in response to external stimuli. Furthermore mutating one gene may affect the expression profile of the others, helping to link those genes into functional pathways and networks. The two major technologies for the large scale expression analysis that emerged from genomics were large scale complementary cDNA sequencing sampling based on standard DNA sequencing methods and the use of DNA array for expression analysis by hybridization. Sequence sampling: Sequence sampling is the direct and fastest way to study transcriptome. In one of the basic approach clones are picked up from cDNA library then theses clones are identified by their comparison with 200 to 300 bp sequence obtained from …

In this video from, we see a mouse embryo developing. Erica Watson, Cambridge University, tells us that studying this process helps us better understand human pregnancy. Under the Microscope is a collection of videos produced by Cambridge University that show glimpses of the natural and man-made world in stunning close-up. You can see the whole series here: bit.ly Erica Watson: “The development of a fetus is elegant yet complex. Amazingly, most fetuses undergo a highly orchestrated sequence of events during development to produce a healthy baby. This suggests that a baby can adapt to changes in the womb, such as to the availability of nutrients from its mother. But how do these environmental changes affect the baby’s health in later life? And is it possible that these adverse changes will alter the development of generations to follow? In other words, does the environment that a baby develops in affect its grandchildren’s growth and development? Our research aims to understand these questions using a mouse model with a genetic mutation that prevents the normal breakdown folic acid (a vitamin). This mutation alters the metabolism of a mouse and causes long-lasting effects on the generations to come. Our hope is to find out how environmental changes caused by a genetic mutation are perpetuated into subsequent generations, even when these generations do not carry the mutation. Since humans and mice use similar genes during development, we can get valuable information from a …

Integrative Biology 131: General Human Anatomy. Fall 2005. Professor Marian Diamond. The functional anatomy of the human body as revealed by gross and microscopic examination. The Department of Integrative Biology offers a program of instruction that focuses on the integration of structure and function in the evolution of diverse biological systems. It investigates integration at all levels of organization from molecules to the biosphere, and in all taxa of organisms from viruses to higher plants and animals. The department uses many traditional fields and levels of complexity in forging new research directions, asking new questions, and answering traditional questions in new ways. The various…

Hacking DNA Compiling code for living systems Genetic modification is getting cheaper and biohackers are making it more accessible. This talk outlines the state of DIYbio and institutional synthetic biology; current challenges in biological programming and why you should be hacking biology. The technology to program biological self-replicating machines is here now. Synthetic biologists are reverse-engineering living cells and building bio-compilers that will facilitate abstract design of complex genetic programs. This talk will show how such a genetic program can be written using freely available parts and design tools. How the DNA can be synthesized, assembled, inserted into a cell culture and the result debugged. The tools to accomplish this exist in two spaces: The wetlab (biological) and the drylab (software). Wetlab access continues to be a limiting factor in participation by the wider community of citizen scientists, hackers and makers. Access restrictions both technological and legal are not foreign to hackers, and biohackers are currently facing obstacles such as GMO laws, expensive lab equipment and restricted access to materials, yet DIYbio groups around the world are building labs, acquiring expertise and making this technology available to everyone. This talk gives an overview of the gap in capabilities between professional labs and DIYbio labs, how it can be overcome, and the unique challenges of biosafety, ethics and intellectual property in biology.
