This Is The Best Salad You Can Make For A Crowd

When I was a teenager, my oldest brother Cole got married to a woman had become the yin to his yang, the butter to his toast, and the apple of his eye: Marianne. Our whole family was drawn to her energy, sense of humor, wit, and generosity, and we were awed by her many talents too! She was a skilled seamstress, and once their daughter Julia started ballet, she sewed her some of the most beautiful and intricate ballet costumes I’d ever seen. Marianne was an equally skilled cook too, and we often argued over who would get the last of the delicious sides and desserts she would bring to family dinners. Marianne was only in early fifties when she...

Seven Good Tools for Creating and Publishing Online Timelines

Creating timelines has been a staple in history teachers' playbooks since the beginning of history. Writing a timeline is a good way for students to chronologically summarize sequences of events and see how the events are connected. When I was a student and when I started teaching timelines were made on large pieces of paper. For someone with handwriting like mine and a keen interest in history, there was never enough room on even the largest paper to make the timeline look nice. Today's students can make timelines online and not have to worry about running out of space nor are they limited to just having text on their timelines. These are my go-to recommendations for creating multimedia timelines. This list...

Give a child a book, or teach her to read?

A first grader picks out a book he would like to check out at the Post Road Elementary School Library, Thursday, Oct. 1, 2020, in White Plains, N.Y. Give a child a book, or teach her to read? The question sounds philosophical, even biblical. It was raised in a recent Boston Globe editorial about how Boston should use more than $400 million in new federal funding for schools. School leaders and communities planning to use this one-time windfall face a tension: invest now to create value after the money is gone, or spend now to address the urgent needs of unfinished learning. Two ideas mentioned in the Globe editorial highlight the two possible approaches: building in-school libraries (offered by Superintendent Brenda...

Authentication of Human Cell Lines Through STR Profiling

About Short Tandem Repeat (STR) Profiling Gaining insight into the human genetic blueprint through the completion of the Human Genome Project (HGP) in 2003 was one of the biggest accomplishments in scientific history. A great deal of what we are is determined by our genetics, and understanding that can help combat disease and other biological issues. With today’s comprehension of genetics, scientists can employ methods to quickly identify particular patterns. One of these is Short Tandem Repeat (STR) profiling, which uses regions of repeated DNA (such as GATA-GATA-GATA) as genetic markers for human identification or cell line authentication. STRs are easily amplified by the polymerase chain reaction (PCR), and multiple STR loci can be examined simultaneously to create a DNA...
