What happened when the first modern humans encountered Neanderthals 60,000 years ago? In 2010, a team led by geneticist Svante Paabo announced that they had reconstructed much of the Neanderthal genome and the analysis showed that modern humans and Neanderthals had interbred, leaving a small signature of Neanderthal genes in everyone outside Africa today.
Did you know that all living cells contain DNA? That’s right, every cell in your body, animals, and plants contains DNA. DNA is short for deoxyribonucleic acid, known as the “molecule of life.” This molecule contains instructions on how to make a living thing; DNA tells you to be you and a strawberry to be a strawberry. Normally, you cannot see DNA with the naked eye. However, if you collect it from thousands of cells, there is enough to be visible.
Would you be happy if a robot gave you flowers? Would you be sad if you saw someone hurt a robot? Those are the types of questions that were on a recent German scientific survey, but why? Why do we need to understand how we feel about robots? Listen to the latest Question Your World Radio Report from the Science Museum of Virginia to learn more.
From coast to coast, some 30 million white-tailed deer make their home in the United States. Deer are the most highly studied mammals in the world, but does the typical homeowner with deer in the yard know how long deer can live? When they sleep? How many babies a doe can have each year?
Enter the hidden world of white-tailed deer outfitted with night-vision cameras and GPS tracking equipment to see them not as common backyard creatures, but as intelligent, affectionate family members.
Our lovely and comfortable home here on Earth is a long way away from the end of our solar system. Here on Earth concepts of boundaries involve rivers, lakes, mountains, human imposed borders, and so on. However, this is not how the limits of our solar system are established. There is not one point that defines the end, but there is definitely an end and it’s really far from here.
Join Team Wood Thrush from Lucille M. Brown Middle School at our Explore the Outdoors Event, Sunday, April 28th from 1:00 until 5:00. These passionate young bird lovers will be at the Community Idea Stations and adjacent Huguenot Park sharing their love of the great outdoors. They will be teaching us how to recognize and "sing" bird calls and talking with us about what is needed to save this endangered neo-tropical bird.
Think about all the music you’ve ever listened to.
“This is so cool!” is becoming a favorite phrase of teenagers in science classrooms all over Virginia. Innovative teachers are encouraging their students to touch, manipulate and experience the surprising power of science. And guess what? These students are deciding that science is cool. Recently, I met with two high school Chemistry teachers and talked with them about why they teach Nanoscience in their classrooms.
The President’s 2014 budget recommendations for NASA last week included money to capture and explore an asteroid in a mission that could someday help protect the earth from impact. Charles Fishburne of WCVE Public Radio talks with Dr.
