Science Bulletins: Duplicate Genes Set Primates Apart
Duplicate genes are becoming a powerful tool to investigate what makes us human. Sometimes one chromosome will acquire more than one copy of a particular gene during cell division and other genetic processes. Over many generations, gene duplications—also called copy-number variants—can accumulate in the DNA of a species. Now that the genomes of humans and other primates have been sequenced, scientists can spot, count, and compare gene duplications among primates and explore how copy-number
Science Bulletins: Scientists Pinpoint Genetic Link to Asthma
For several decades, researchers have been collecting medical and genetic data on the Hutterites, a rural communal population that lives in small communities in the north-central United States and central Canada. Because the isolated Hutterite communities have uniform environmental and lifestyle conditions, the data are enabling researchers to isolate the genetic contributors of disease. A team led by Carole Ober of the University of Chicago recently found distinct genetic mutations that increa

Mass murder of Kherson Jews
Vanda Kriger, who was born in 1925 in Kherson and lived there during the war years, describes how in late September 1941 her mother, together with other Jews, was transported from a prison in Kherson to a murder site, where they were shot. She notes the three places where Jews from Kherson and prisoners of war were executed and buried in mass graves in Kherson and surrounding areas.

Endocrine / Reproduction
This sequence provides the information and opportunities necessary for students to acquire integrated knowledge of the structure and function of the endocrine and reproductive systems in humans. Although all of the biological systems are clearly interrelated, the endocrine and reproductive systems are intimately linked. Much of what you learn about hormonal control and steroid biochemistry of the endocrine system will be referred to and used in teaching reproductive physiology.
Boiler Bytes: "Blithe Spirit"
Engineering is not usually the first thing that comes to mind when you think about a stage play. But a unique academic partnership has given engineering majors the opportunity to add a little drama to their studies. Recently, two such students played important roles in Purdue Theater's production of the Noel Coward play, Blithe Spirit.

California's State Insect- Dogface Butterfly Life Cycle Documentary 720p HD
The California Dogface (Zerene eurydice, also known as the "Dog's Head Butterly") is California's state butterfly (and state insect, as designated in 1972). Its life cycle is showcased here in great detail, featuring time lapse sequences of never before seen events in the growth and development of this amazing creature. These butterflies are not very well known, and not commonly found in cities and gardens. This is a great resource to help build background knowledge and to help make real wo
Giant Silkmoth Emerges/Expands Wings Realtime/Timelapse
Here we see the original raw footage in both realtime and timelapse. A male Euryalus SIlkmoth (Hyalophora euryalus) struggles out of his cocoon, and then expands his wings. This moth species typically has a wingspan of about 4-5 inches across from wingtip-to-wingtip, and is sometimes mistaken for a bat or small bird when encountered flying at night. What a great resource to help build background knowledge and to help make real world connections between nature and the classroom. (2:11)

The Un-Epic Battle
Accuracy of measurement in navigation depends very much on the situation. If a sailor’s target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed if off just the smallest bit. Many of the measurements made while navigating involve angles, and a small error in the angle can translate to a much larger error in position when traveling long distances.
