"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

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

Imagine It's the Year 2020: Thinking About Genetics Now
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a look at some of the questions that go hand-in-hand with genetic cloning technologies. The site opens by telling kids that in the future, technologies like cloning may be very common and that some of the decisions we will need to make in coming years are hard. Then, they are asked to imagine that it is the year 2020 and to take a peek at what's on the minds of one futu

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.
