"I Was More of a Citizen": A Puerto Rican Garment Worker Describes Discrimination in the 1920s
We generally think of Puerto Rican migration to the U.S. mainland as largely a post-World War II phenomenon, since more than 800,000 Puerto Ricans came to the United States between 1940 and 1969. But immigration actually started much earlier in the century; between 1915 and 1930 more than 50,000 Puerto Rican migrants headed for the United States--especially New York City. The new immigrants faced a mixed reception, particularly from immigrants from other countries. In this interview for the radi
"I Was Able to Make My Voice Really Ring Out": The Women's Emergency Brigade in the Flint Sit-Down S
The Women's Emergency Brigade, which Genora Johnson Dollinger helped organize, saved the 1936 sit down strike at Flint, Michigan more than once. In this 1976 interview with Sherna Gluck, Dollinger recalls the famous "Battle of the Running Bulls" when police--bulls--tried to regain control of the GM plant by force. Dollinger and the other organizers of the Women's Emergency Brigade faced constant sexist attitudes in their efforts to win the strike, even as they demonstrated their determination to
Junk in Space
There are currently millions of man-made orbital ruins that make up "space junk". Space junk can be anything from hatches blown off space modules, paint fragments from the space shuttle, or satellites that no longer work. On this website you will help to capture junk that's floating out there in space. Each time you capture junk, you also find a short description of the junk, how it arrived in space and links to additional information. This is an activity that takes less than 5 minutes and is a
Galaxy-Quasar Associations: Is the Big Bang Bung?
When we see a galaxy and a quasar near each other in the sky, it might be because they are really near each other, or it might be that they are far apart and just along the same line of sight. Tests performed by Alan Stockton (Astrophysical Journal 223:747-757, "The Nature of QSO Redshifts", 1978) on a sample of such pairs have shown that some galaxy-quasar pairs have the same redshift and so are accepted as being at the same distance. Other pairs with very different redshifts however have been
Functional and Structural Insights Revealed by Molecular Dynamics Simulations of an Essential RNA Ed
RNA editing ligase 1 (TbREL1) is required for the survival of both the insect and bloodstream forms of Trypanosoma brucei, the parasite responsible for the devastating tropical disease African sleeping sickness. The type of RNA editing that TbREL1 is involved in is unique to the trypanosomes, and no close human homolog is known to exist. In addition, the high-resolution crystal structure revealed several unique features of the active site, making this enzyme a promising target for structure-base

Food Insufficiency Is Associated with High-Risk Sexual Behavior among Women in Botswana and Swazilan
Background
Both food insufficiency and HIV infection are major public health problems in sub-Saharan Africa, yet the impact of food insufficiency on HIV risk behavior has not been systematically investigated. We tested the hypothesis that food insufficiency is associated with HIV transmission behavior.
Methods and Findings
We studied the association between food insufficiency (not having enough food to eat over the previous 12 months) and inconsistent condom use, sex exchange, and other measure
Following the Flow - Partners Video Magazine
Researchers are discovering how nano-scale tracers can uncover the sources of pollution in America's farm fields and waters. Following the Flow is a segment from Partners Video Magazine's latest episode, The Science of Small. To view the entire episode visit: http://www.csrees.usda.gov/newsroom/partners/partners.html
Folding pathway of the B1 domain of protein G explored by a multiscale modeling
The understanding of the folding mechanisms of single domain proteins is an essential step in the understanding of protein folding in general. Recently, we developed a mesoscopic CABS protein model which was successfully applied in protein structure prediction, studies of protein thermodynamics and modeling of protein complexes. In the present research this model is employed in a detailed characterization of the folding process of a simple globular protein, the B1 domain of IgG-binding protein G

What Do You Know About Archeology?
This OLogy activity tests kids' knowledge about excavation strategies, the tools archaeologists use, and more with an interactive quiz. The 10-question multiple-choice test covers a wide range of topics, from "Why do archaeologists create a map of the site before they dig?" to "Archaeologists look for different soil layers that they identify by color and texture. If the layers haven't been disturbed, what can they tell us?" After making their 10 selections, kids can check their answers with a pa
Discovery Collection: Marine Animals
Marine Animals is one of the AMNH Education Department's many collections of specimens and artifacts gathered the world over by explorers and scientists. In its online Discovery Collection form, Marine Animals includes an educator's Guide with suggestions for how to use the Marine Animals Discovery Collection in the classroom.
Who Are the Plants?
This online article, from Biodiversity Counts, offers a brief overview of the plant kingdom. Specifically, it covers: why plants have their own kingdom, Plantae; what separates the kingdom's two very basic categories; the plant kingdom's 10 divisions, including the number of species in each; and why some organisms that seem like plants belong instead to the kingdom Protista or the kingdom Fungi.
Plant/Arthropod Interactions
This online article, from Biodiversity Counts, offers insight into how plants interact with arthropods. It has: an explanation of the difference between detrimental and mutually beneficial relationships; some of the chemical and mechanical modifications plants have made to attract helpful arthropods and fend off harmful ones; a detailed overview of pollination, with descriptions of seven common pollination syndromes; a detailed overview of plant defense mechanisms; and a series of questions stud
Helpful Hints for Field Sketching
This online article, from Biodiversity Counts, offers insight into the task of field sketching. After discussing the difference between seeing and observing, the article offers tips designed to help make students better at observational rendering. The six hints discussed are proportions, perspective, volume, simplifying, practicing a lot, and having fun.
