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.

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

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

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
