Climate science, Vikings and other invasive species
Look around the English countryside and you'll find animals and plants that shouldn't be there -- from Muntjac deer to Mitten crabs, Harlequin ladybirds to Tree of Heaven.
6.1 Introduction
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

Jennifer Egger is faculty at Otis College of Art and Design. She teaches Typography in the Digital Media Department. This video represents the very basics of learning about typography, the vocabulary of typography.
Health, safety and risk assessment are of paramount importance both in the laboratory and the field. This unit will help make you more aware of the hazards and risks involved in laboratory and field-based research work, as well as giving you an overview of the legal requirements attached to this work. The unit discusses issues involved in the handling chemical and biological agents, basic safety procedures and common field-work hazards.

Nick Bostrom provides an introduction to the Global Catastrophic Risks Conference and briefly addressing some of the key themes running through it.
In this exercise, students isolate and analyze DNA from food plants in a supermarket, or from common backyard plants. Extracting plant DNA is often difficult using conventional means because undesirable material including PCR inhibitors often co-purifies with the DNA. The novel approach used in this exercise is simple and quick, and also avoids the use of dangerous organic reagents. Students crush plant material (spinach leaves in this exercise) onto special cards originally used to archive bloo
The pea aphid, Acyrthosiphon pisum, is a versatile laboratory organism. This experiment investigates the response of pea aphids to an alarm pheromone normally produced in response to predator attack. The responses of aphids feeding on good quality and on poor quality long bean plants will be compared and discussed in terms of the costs and benefits of antipredator behaviors. The life cycle of the pea aphid is demonstrated and information about obtaining, rearing, and working with pea aphids is p
This cell membrane physiology laboratory uses sheep red blood cells to determine: (1) the isotonic and hemolytic molar concentrations of electrolytes and nonelectrolytes, and degree of electrolyte dissociation; (2) the diffusion rate of penetrating molecules of varying size and lipid solubility; and (3) the relationship of molecular size, number of hydroxyl groups, and partition coefficient to diffusion rate. Student research teams then design an experiment using the acquired techniques to deter
Don Boudreaux of George Mason University talks with EconTalk host Russ Roberts on some of the common misunderstandings people have about prices, money, inflation and deflation. They discuss what is harmful about inflation and deflation, the importance of expectations and the implications for interest rates and financial institutions.
John Taylor of Stanford University talks with EconTalk host Russ Roberts about the fundamental causes of the financial crisis of 2008. Taylor argues that the housing bubble of the early 2000s was caused by excessively loose monetary policy, in particular, a sustained period of excessively low interest rates pursued by the Federal Reserve. Other topics covered include rules vs. discretion in monetary policy and the risks of inflation in the coming months. The conversation concludes with a discuss
In 1965, Gordon Moore observed that the number of transistors on a silicon chip doubled every technology generation (12 months at that time, currently 18-24 months). He predicted that this trend would continue for a while. Forty years later, Moore's Law continues to hold. Since the number of transistors in a circuit is a measure of the circuit's computational power, the doubling of transistor counts compounded over a 40 year period has led to an enormous increase in the performance of electronic
The Center for Agriculture at UMass Amherst is studying how to improve methods that deter pesticide runoff and protect water supplies. Learn how researchers are evaluating how various plants, known as vegatative filter strips, can protect public health.
MacRetina simulates data from retinal ganglion cells in the eye to the brain.
By sampling neural activity while stimulating the retina with small spots of light, students can see the dynamic excitatory and inhibitory responses of these neurons in the simulation, and map the organization of the retinal region that drives the cell's receptive field.
MacRetina is modeled accurately on published data and is a realistic simulation of a lab experiment that would otherwise be beyond the reach of the
Lecture on Biotechnology; its applications, its implications, risks and the challenges this new technology brings
Following a very successful career that saw him lead a number of well-known business ventures, such as PizzaExpress and bookshop chain Borders, Luke Johnson became Chairman of Channel 4 Television Corporation in January 2004. In this presentation, Luke Johnson draws on his own experience as an entrepreneur to discuss the business of risk. How does risk affect us today in our lives? Hear from the man who has ridden through his fair share of storms in the business world and who has lived through t
In this course, we will address how transcriptional regulators both prohibit and drive differentiation during the course of development. How does a stem cell know when to remain a stem cell and when to become a specific cell type? Are there global differences in the way the genome is read in multipotent and terminally differentiated cells? We will explore how stem cell pluripotency is preserved, how master regulators of cell-fate decisions execute developmental programs, and how chromatin regula
Jonathan Rauch, of the Brookings Institution and the Atlantic Monthly, talks with EconTalk host Russ Roberts about the evolution of the Chevy Volt, GM's planned electric car. Due to the transparency of GM's effort, Rauch was able to spend a great deal of time on site at GM writing a piece for the Atlantic Monthly on GM's plans and hopes. Rauch discusses the huge risks, GM's past failures, and GM's hopes that the Volt might change the company's culture. The conversation closes with a discussion
