Space Station Live: Aerosols in a CATS Eye
NASA Public Affairs Officer Nicole Cloutier-Lemasters talks with Dr. Matthew McGill and Dr. John Yorks of NASA’s Goddard Space Flight Center in Greenbelt, MD, about CATS (Cloud-Aerosol Transport System), their aerosol-measuring remote sensing unit that’s flying to the International Space Station on a cargo vehicle next week. CATS uses a LiDAR system to provide a better understanding of particulate coverage in the atmosphere for scientists modeling Earth’s climate feedback processes. Watc
Internet Scout Project
This is an article appearing in the January 2002 issue of Scientific American detailing what Advanced Cell Technology (ACT) claims is the first human cloned embryo. This online version describes the research that ACT calls the "dawn of a new age in medicine" and includes links to further information, covering ethical and legal considerations surrounding cloning and the difference between reproductive and therapeutic cloning.
Internet Scout Project
As a free public service, the Emergency Email and Wireless Network provides citizens with email, cell phone, or pager notifications from your local, regional, and national government sources. Users can choose to receive information about severe weather in their area; electric, gas, and water outages; daily weather forecasts; national disaster news; and more. On the registration page, visitors input their email address, home county, zip code, and the type of notification they would like, and can

Mechanisms of DNA replication, transcription, translation. Structure of genes and chromosomes. Regulation of gene expression. Biochemical processes and principles in membrane structure and function, intracellular trafficking and subcellular compartmentation, cytoskeletal architecture, nucleocytoplasmic transport, signal transduction mechanisms, and c
Biological Membranes and Transport
Description not set
DNA microarray analysis is one of the fastest-growing new technologies in the field of genetic research. Scientists are using DNA microarrays to investigate everything from cancer to pest control. Now you can do your own DNA microarray experiment! Here you will use a DNA microarray to investigate the differences between a healthy cell and a cancer cell.
Make a DNA Model
By building their own DNA model in this OLogy activity, kids learn about the unique genetic code that's found in every cell of their bodies. The activity begins with a brief look at how all living things are made of cells, and what that makes them unique is DNA. Then, using toothpicks, colored paper, and other common supplies, students create a 3-D model of DNA and "do the DNA twist" to make it look like a double spiral. Interspersed throughout the activity are kid-friendly descriptions of the d
In this video segment from The Secret of Life school video, "Sex and the Single Gene" follow as a single fertilized egg cell divides, differentiates, and assembles into the tissues and organs of a new organism.
Test your knowledge about cell differentiation, cell function and tissue culture.
National Middle School Science and Technology Bowl
Two competitions: an academic competition in which middle school students answer fast-paced questions about math and science (earth, physical, life, and general science) and a model fuel cell car competition that challenges students to design, build, and race model cars.
Clearing Techniques for the Study of Vascular Plant Tissues in Whole Structures and Thick Sections
The clearing technique presented here in 4 exercises changes the refractive properties of various organelles without altering the structural integrity of the cells. It effects a refractive uniformity among cellular organelles so that their distinctive and contrasting features can be revealed with phase contrast and Nomarski interference microscopy or through selective staining in conjunction with bright field optics.
Antibody-protein interactions: benchmark datasets and prediction tools evaluation
Background The ability to predict antibody binding sites (aka antigenic determinants or B-cell epitopes) for a given protein is a precursor to new vaccine design and diagnostics. Among the various methods of B-cell epitope identification X-ray crystallography is one of the most reliable methods. Using these experimental data computational methods exist for B-cell epitope prediction. As the number of structures of antibody-protein complexes grows, further interest in prediction methods using 3D s
Improving Your Commute
Road traffic is a challenging societal problem, and with the increasing crowding of areas in and around cities, it is only becoming worse. With the proliferation of wireless connectivity, smartphones (think cheap embedded computers), it is now possible to continuously monitor urban areas using mobile sensors carried by people
Virtual yeast cell
This rich learning object is used to introduce yeast cytology to students taking Module D24BS3 Brewery Yeast Management as part of the MSc in Brewing Science. The virtual cell permits the students to understand structure and function of yeast organelles.
Human Cloning and Human Rights: Promises and Perils
Ignore the noisy debate around cloning, Rudolf Jaenisch quietly insists, and instead look closely at the biology involved. First, note that there are two different kinds of cloning: reproductive cloning, the attempt to create an exact replica of a human being, which Jaenisch believes to be both biologically flawed and morall
20.441J Biomaterials-Tissue Interactions (MIT)
This course covers the principles of materials science and cell biology underlying the design of medical implants, artificial organs, and matrices for tissue engineering. Methods for biomaterials surface characterization and analysis of protein adsorption on biomaterials. Molecular and cellular interactions with biomaterials are analyzed in terms of unit cell processes, such as matrix synthesis, degradation, and contraction. Mechanisms underlying wound healing and tissue remodeling following imp

RVC 50 - Immune-mediated diseases and the role of Regulatory T cells in dogs and humans
A number of diseases arise because the immune system begins to attack the body’s own cells. Here Dr Oliver Garden describes how these diseases arise and his research into the role of a particular type of immune cell, the regulatory T cell, in this phenomenon across species.
