Anyone who has ever watched “Law and Order” or “CSI” knows: obtaining and analyzing DNA evidence features prominently in many of its fictional criminal cases. But leaving such TV dramatizations aside, over the last two decades, DNA evidence has come to play an increasingly routine and important role in the U.S. law enforcement and justice systems. Technological innovations within science and social policy have both played a role in this process.
Do you think the most used magnet in your home is the one on your refrigerator door? Well, that’s actually unlikely considering that magnets are used in just about everything from your computer to your blender. Since magnets are everywhere, you may wonder if there is anything new to learn about them. How about the use of magnets in nanoscience and green technologies like electric cars and wind energy generation?
There are some folks that believe the world is going to end for a variety of reasons on December 21, 2012. Some think that a rogue planet will crash into the Earth while others are of the impression that a series of global natural disasters will bring our day-to-day business to a halt and usher in the end of times.
Another major development in the advancement of Virginia as a high-tech state occurred this week. The Babcock & Wilcox Company announced that the production-standard control room prototype for its small modular reactor is now operational. This engineering simulator is a key milestone in the B&W mPower development program. “Our vision is simple and I think it’s bold.
Have you ever wondered how your brain cells came into being? Why didn’t those cells develop into muscle cells instead? How we develop and age is a complex process. DNA is not the whole story and nature versus nurture isn’t so clear cut. While every cell in our body contains the same genetic information, it’s epigenetics (or “outside genetics”) that distinguishes our muscle cells from brain cells.
Happy Thanksgiving Everyone! One of the most common misconceptions about this tasty holiday is based around some simple chemistry. The amino acid in question is Tryptophan! The most popular source of this culinary chemical on your dinner table is turkey, however there is a little myth that we need to clear up.
With cooler weather approaching, many students, teachers and parents are beginning to prepare for Spring Science Fairs.
Do you think it is ethical for medical science to do more than simply treat illnesses and try to make us “better than human?” Are the things we are doing today such as cognitive enhancement drugs and genetic modification unprecedented? Join Bioethicist Dr. Allen Buchanan at Chesterfield County Public School’s Visiting Author Program on October 23rd at 6:30 p.m as he explores the promise and perils of our current medical revolution.
