Learning outcomes
From the mouse-deer to the elephant, plant eaters come in all shapes and sizes. But how do they manage to flourish on a salad diet? In this unit we will examine the special features that allow them to extract their nutrients from leaves, and see how some plants protect themselves from these predators. This is the fourth unit in the ‘Studying mammals’ series.

2.1 Introduction
In the 18th and 19th century evolutionary biologists, including Darwin, emphasised the similarities between natural evolution and artificial ‘ improvement’ of livestock under domestication. They believed that studying domesticated animals and plants could illuminate the mechanisms of natural evolution.

2.2 Chaperones help polypeptides to fold
In this unit we explore how proteins are the 'doers' of the cell. They are huge in number and variety and diverse in structure and function, serving both the structural building blocks and the functional machinery of the cell. Just about every process in every cell requires specific proteins. The basic principles of protein structure and function which are reviewed in this unit are crucial to understanding how proteins perform their various roles.

2.4 Analysis of nucleic acids by electrophoresis and hybridisation
This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nu

Predictive medicine
In this unit you will learn how advances in genetics could change the way in which diseases are diagnosed and managed. The advent of predictive medicine, based on more detailed DNA profiling of individual genotypes using technologies like gene chips, rather than screening for one gene at a time, may shift the relationship between doctor and patient. People will be seeking advice on how to manage their susceptibilities or genetic risks, rather than looking for treatment for an already existing di

STS.330 History and Anthropology of Medicine and Biology (MIT)
This course explores recent historical and anthropological approaches to the study of medicine and biology. Topics include histories of bodies and embodiment in medicine; institutional and social genealogies and futures for genes and genomes; the role of science and medicine in racial formation; epidemics and emergent diseases; new reproductive technologies and socialities; the laboratory and field lives of animals, plants, microbes, molecules, and environments.

AlgTop9: Applications of Euler's formula and graphs
We use Euler's formula to show that there are at most 5 Platonic, or regular, solids. We discuss other types of polyhedra, including deltahedra (made of equilateral triangles) and Schafli's generalizations to higher dimensions. In particular in 4 dimensions there is the 120-cell, the 600-cell and the 24-cell. Finally we state a version of Euler's formula valid for planar graphs. This is the ninth lecture in this beginner's course on Algebraic Topology, given by Assoc Prof N J Wildberger at UNSW

Formation of Acetyl Co-enzyme A
This page explains the formation of Acetyl Co-enzyme A which is key to the synthesis of many organic molecules in cells. An acetyl group is a simple two-carbon-atom molecule which is sufficiently reactive to make it possible to use as a building block for larger carbon skeletons. A large number of molecules that are synthesised in cells are built from two-carbon acetyl groups. An acetyl group derives from ethanoate (acetate) and is named acetyl when it forms a group within a larger molecule. I

The Water Cycle - by StudyJams
The water cycle is the constant movement of water through the Earth and its atmosphere.  Water on the ground evaporates, becoming water vapor.  The vapor rises, becomes clouds, and then falls back to the Earth as rain, snow, sleet, or hail.  Learn more about the water cycle with this cartoon animation from StudyJams.  A short, self-checking quiz is also included with this link.

Unlearn Your MBA - David Heinemeier Hansson (37signals)
David Heineimeier Hansson, the creator of Ruby on Rails and partner at 37signals in Chicago, says that planning is guessing, and for a start-up, the focus must be on today and not on tomorrow. He argues that constraints--fiscal, temporal, or otherwise--drive innovation and effective problem-solving. The most important thing, Hansson believes, is to make a dent in the universe with your company.

4.4 Radioactive waste disposal

Most fission products from nuclear reactors are solid at ordinary temperatures. They cluster around atomic mass numbers 90 and 140 (see, for example, Equation 2). From the point of view of waste disposal, the problem is that most of them are highly radioactive. The common radioactive isotopes produced in nuclea

Natural Inquirer Journals: Urban Forests
What are urban forests? Urban forests are the trees and other plants that grow where people live, go to school, work, and play. Even if you live in a rural community, the trees in your yard, around buildings, and in parks are called urban forests. Calling them urban forests helps you to see that they are different from the kind of forests that grow in large undeveloped areas. Urban forests include trees in community parks and other public land, along streets, in neighborhoods, around businesses
