Biotechnology: Detection of Cell Clones
Professor George Wolfe discusses detection of cell clones in this video from Thinkwell's online Biology series. The video uses lecture format along with notes and illustrations on a board. Run time 08:59.
Reading the Code of Life DNA is central to cell activity, replicating with great fidelity and carrying the information for all proteins. Organisms also regulate the products made from genes in an effort to conserve energy and adapt to new environments.
Jeremy Siegel: Interest Rates Look Stable, but Beware the China Bubble
The U.S. economy may be getting stronger, but that doesn't mean interest rates will go up when the Federal Reserve meets next week on January 31. According to Wharton finance professor Jeremy Siegel, interest rates should hold firm at their current level for quite a while, and "the big question for the market is whether there will be any drops at all this year." He believes there is "a balance in the economy between strength and moderate inflation," and the Fed is unlikely to move interest rates
Fire Ant Border Wars
A quarter million strong, nothing can stop these ants once they start to attack. Food is a matter of life or death. So the fighting is fierce. This movie shows how competing ant colonies fight. Run time 01:07.
Cells - Centers for the Week of 8/30/10
Mrs. Matthews students rotate through science centers each week. This week, the class is learning about living things, the parts of a plant and animal cell, and unicellular organisms. Their centers for the week include (1) a video about microbes found on Watchknow called Magic School Bus is in a Pickle (2) three interactive microscope websites on the Whiteboard (3) an experiment with a chicken egg (one large cell) soaked in vinegar to reveal the membrane (4) an art activity where the stud
Masters of Disguise
The natural world is filled with animals trying to eat other animals and trying to avoid being eaten. This pressure to find food or to keep from becoming someone else's dinner has, over millions of years, produced an incredibly effective way to escape detection by predators or prey: camouflage. This video segment explores the world of camouflage, including some of the methods and benefits of this important evolutionary strategy. Footage from NOVA: "Animal Impostors." Closed captioning included.Â
Recycling - Paper
This brief video shows the process of recycling paper from start to finish. Run time 01:03.
Biomes Interactive Site
The distribution of plants and animals around the world is anything but random. Instead, it is a result of the interplay of individual environmental tolerances of species and the environmental conditions, especially variations in temperature and precipitation. These interactions result in biomes, the categories into which ecologists organize similar communities of plants, animals, and the environmental conditions in which they live. This interactive resource adapted from NASA features some of th
Nanoelectronics 101
Semiconductor device technology has transformed our world by making possible supercomputers, personal computers, cell phones, ipods, and much more that we now take for granted. Moore's Law observes that the number of transistors (the basic building blocks of electronic systems) per electronic chip doubles each technology generation. This doubling of transistor density each technology generation has continued since Gordon Moore, one of the co-founders of Intel, made his observation in 1965. It ha
Engineering Nanomedical Systems
This course will cover the basic concepts of design of integrated nanomedical systems for diagnostics and therapeutics. Topics to be covered include: why nanomedical approaches are needed, cell targeting strategies, choice of core nanomaterials, technologies for testing composition and structure of multilayered nanomedical systems, optimizing zeta potentials, design and testing of cell and intracellular targeting systems, in-vivo issues, drug delivery and proper dosing, assessing efficacy of dru

Bad Language [Audio]
Speaker(s): Dr Emma Byrne, Dr John Gallagher, Dr Rebecca Roache | Language allows us to communicate. It also allows us to charm, shock, delight, and offend. It is political and we can use it to harm and manipulate. And some words are just not okay in polite company. Should there ever be restraints on what can be said? If so, what kind? In this Forum event, we navigate the deeper issues around swearing, slurring, and slander. Swear-jars at the ready! Emma Byrne (@SciWriBy) is author of Swearing i
Securing Financially Sensitive Environments with OpenBSD
This thesis investigates the use of a free, open source
UNIX-based operating system in providing security features
to a financially sensitive business function such as a
treasury.
We start by examining some of the main security features
(such as the pf firewall and systrace policies) which are
included with the operating system, how they work and how
such features can be used within a financial environment.
We then examine possible probl
River Biomes: Tidal Marshes
A one minute video that explains what a tidal marsh is and what value they are to plants and animals. The video needs a lot of reinforcement from the teacher in the form of maps, handouts, and additional graphics that help explain fresh and salt water among other things.
