Homeostasis - kidneys and water balance Substances are moving in and out of the cells of your body all the time. To understand why the water balance is so important in homeostasis, and to make sense of how your kidneys work, you need to know about diffusion, osmosis and active transport. is the spreading out of the particles of a gas or any substance in solution. It is caused by the random movement of the particles. The higher the temperature, the faster the particles move and the faster diffusion takes place. Diffusion results in the overall (net) movement of particles from an area of high concentration to an area of low concentration down a concentration gradient.
PennCNV PennCNV: copy number variation detection Welcome! PennCNV is a free software tool for Copy Number Variation (CNV) detection from SNP genotyping arrays. Currently it can handle signal intensity data from Illumina and Affymetrix arrays. With appropriate preparation of file format, it can also handle other types of SNP arrays and oligonucleotide arrays. PennCNV implements a hidden Markov model (HMM) that integrates multiple sources of information to infer CNV calls for individual genotyped samples. Journal home : Nature Raphael Lis, Charles C.

Protein Data Bank - RCSB PDB A Structural View of Biology This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease. As a member of the wwPDB, the RCSB PDB curates and annotates PDB data. The RCSB PDB builds upon the data by creating tools and resources for research and education in molecular biology, structural biology, computational biology, and beyond. Use this website to access curated and integrated biological macromolecular information in the context of function, biological processes, evolution, pathways, and disease states.

GISS ICP: Earth Climate Course Earth Climate Course: What Determines a Planet's Climate? This module is designed to connect cutting edge NASA research with the teaching and learning of core science and mathematics concepts and skills while addressing state and national education standards. Since an important goal of research is creating new knowledge, the process of science inquiry and the research tools used to do research play a major role in all the lessons. Presented with a science problem, students seek answers and consensus by experimenting with physical and computer models, collecting and analyzing their own measurements, and conducting inter-comparisons with real world data from satellites and ground-based observations. NASA missions and related Earth and space Science topics provide the real world problem context for student investigations. The outline for this module's lessons is shown below in the "Topic" column of the table.

ASHG 2010: 1000 Genomes Project Tutorials ASHG 2010: 1000 Genomes Project Tutorial Videos The 1000 Genomes Project has released the data sets for the pilot projects and for more than 1000 samples for the full-scale project. A tutorial for how to use the data was held at the 2010 American Society of Human Genetics (ASHG) annual convention on November 3. Logical Fallacies and How to Spot Them Logical Fallacies and How to Spot Them In the Evolution vs. Creationism debate, it is important to be able to spot all the logical fallacies that Creationists tend to throw around. This essay covers many bare essentials of logical thinking, as well as ways to critically evaluate an argument. The logical fallacies listed here are the ones most often used by Creationists, although Creationists have, to date, used almost every single logical fallacy in existence to "prove" their case. Each fallacy will have its own little paragraph, describing it, why it is fallacious and how to counter it.
PLINK This page describes some basic file formats, convenience functions and analysis options for rare copy number variant (CNV) data. Support for common copy number polymorphisms (CNPs) is described here. Copy number variants are represented as segments. These segments are essentially represented and analysed in a similar manner to how PLINK handles runs of homozygosity (defined by a start and stop site on a given chromosome). Allelic (i.e. basic SNP) information is not considered here: PLINK skips the usual procedure of reading in SNP genotype data. Here we assume that some other software package such as the Birdsuite package has previously been used to make calls for either specific copy-number variable genotypes or to identify particular genomic regions in individuals that are deletions or duplications, based on the raw data.
Sword Swallowing X-rays Dan Meyer being x-rayed Lateral X-ray of Dan Meyer, courtesy Dr. Edwin Donnelly, Vanderbilt Medical Center 5 Creative Ways to Teach the Cell 5 Creative Ways to Teach the Cell 1. 3 D Cell – this is a standard project for entry level biology classes, where students use various objects from around the house to design a three dimensional cell. Popular models are made of clay, cardboard, or styrofoam. Pros: Students seem to enjoy the project and you end up with a lot of amazing models. Cons: Can be expensive, difficult to store, or attract bugs if they are made of candy or other perishables, mostly done as individual projects. 2.
Breath-holding and its breakpoint Introduction The precise mechanisms explaining breath-holding and causing the breath at breakpoint are unknown. There are several useful reviews (Mithoefer, 1965; Godfrey & Campbell, 1968, 1969; Porter, 1970; Campbell & Guz, 1981; Lin, 1982; Nunn, 1987). Breath-holding is an unstable state with changes occurring in many interrelated variables.
