Upper Beginner #24 - Feasting on the Bullet Train in Japan
Learn Japanese with JapanesePod101.com! The person sitting across from you on the six-hour Japanese bullet train ride has been eating Japanese snacks since you left the station. He has devoured everything the Japanese cart attendant has brought by, from Japanese crackers to fish, and he has probably eaten more than you do in an entire [...]

Introduction to microscopy
The unit provides an introduction to microscopy and the operation of a simple light microscope, of the type found in histology units and teaching laboratories. It outlines different methods used for preparing and staining tissue sections for microscopy, and explains how different stains can be used to identify particular cells, pathogens and anatomical structures.Author(s):
Detecting Down’s syndrome in the unborn fetus
Down's syndrome is the condition that is screened for the most in pregnant women because of the increased risk with the increasing age of mothers. This unit describes several bioanalytical tests, and how these are used in conjunction with scans to screen and diagnose the condition. First published on Fri, 20 Jul 2012 as
4.2 Intermediate forms In essence, the argument about intermediate forms runs as follows. If whales evolved from a terrestrial ancestor through the accumulation of small differences over time, we should expect to find the fossils of a number of ‘missing links’, i.e. creatures with a mixture of terrestrial and aquatic characteristics. In fact, we might expect to find a succession of such animals, each a little bit more whale-like and a little bit less well adapted to life on land than its predecessor. To m
3.2 Natural dives The physiology of the diving response can be studied in the laboratory, but investigating the behaviour of a diving mammal in its natural environment can be more of a problem. However, modern physiological techniques have made it possible to record continuously physiological variables (such as heart rate) and information on depth and position during the spontaneous dives in the wild that are part of the animal's normal behaviour. Most such findings show that the majority of an animal's dives
2.7 … and becoming more intelligent Intelligence is a useful commodity: it can help an animal to make sense of its environment and cope with the demands of social behaviour (including courtship and competition). Hunters tend to be relatively intelligent, and otters, pinnipeds and cetaceans, for example, share a playful curiosity that is characteristic of animals that catch other animals for a living. Some especially extravagant claims have been made for the intelligence of the toothed whales, largely because these animals use c
2.1 Land versus water Mammals share a number of biological characteristics that mark them out as members of the class Mammalia. Many of these are adaptations to a life on land. For example: Mammals give birth to young at a relatively advanced stage of development and feed their young on milk. Most mammals have hair, or fur, covering part or all of the body. Mammals have a high metabolic rate and maintain a relatively high and constant body temp
7.2.1 The equilibrium constant An expression for the equilibrium constant of a reaction can be put together from the concentrations of the reactants and products at equilibrium. A concentration of a reactant or product is represented by enclosing its chemical formula in square brackets. Thus, the concentration of NO(g) is written [NO(g)]. To write down the equilibrium constant of a reaction, we start with the concentrations of the products. Each one is raised to the power of the number that precedes it in the reactio
6.3.1 Refinements and difficulties In Section 6.2, we said that inter-axis repulsions vary in the order: non-bonded pair–non-bonded pair > non-bonded pair–bond pair > bond pair–bond pair There is evidence for this in the inter-bond angles in molecules. For example, in wat
4.5 More about covalent bonding So far, the valencies in Table 1 have just been numbers that we use to predict the formulae of compounds. But in the case of covalent substances they can tell us more. In particular, they can tell us how the atoms are linked together in the molecule. This information is obtained from a two-dimensional drawing of the structural form
1.2 Chemical elements Atoms of the same atomic number behave virtually identically in chemical reactions. They are therefore given the same chemical name and chemical symbol. For example, the atom of atomic number 6, which is shown in Figure 1, is a carbon atom, whose symbol is C. All materials are made of atoms, but there is a special class of substan
