Sighting of Northern Saw-whet Owl

Students with owl

Imagine our excitement when a Northern Saw-whet owl was discovered near our school property! When my Environmental Science class examined the beautiful creature closely, we saw that it had been banded as part of a U.S. Government program. We reported it, using the number indicated on its leg band, and are anxiously awaiting the information regarding where its journey began. How exciting to be a part of an international investigation on behalf of the Saw-whet owl! It is very rewarding for the students to be able to see, touch, and experience an animal compared to learning about it from a book.

Making a Baby With Three Parents – World Science Festival

This week, British legislators in the House of Commons voted to enact laws that would make the U.K. the first country to allow the in vitro fertilization technique known as mitochondrial transfer. Because the resulting offspring contains DNA from three separate people (two parents provide the nuclear DNA, which controls most of our personal traits, and a second woman provides mitochondrial DNA, which is thought to control basic cell functions), the technique is also referred to as “three-parent IVF,” a term almost as controversial (as journalist and physician Emily Senay points out in the video above) as the procedure itself.

In the clip from the 2014 World Science Festival program “Designer Genes: Fashioning Our Biological Future,” fertility specialists Paula Amato and Jamie Grifo discussed the science behind this technique.
