Upcoming Live Streams

Invertebrate Biology Series: Molting and Metamorphosis, Part I

Date: Thursday, April 9, 2020
Time: 12:00 p.m. (EDT)
Audience: General audience

Insects, arachnids, crustaceans, and other arthropods all demonstrate a distinct pattern of growth and development over the course of their lives, known as metamorphosis, which is characterized by distinct changes in their body form. There are many different types of metamorphosis, but all arthropods are united in the way that they undergo metamorphosis: molting – they shed their skin! Join DNALC Educator and Long Island Aquarium Entomologist Jeffry Petracca for the first episode in our Invertebrate Biology series for a discussion of invertebrate growth through molting and metamorphosis!

DNALC Chat: AP® Biology

Date: Thursday, April 9, 2020
Time: 2:00 p.m. (EDT)
Audience: AP® Biology students and educator

The College Board has announced that this year’s AP® Biology Exam will consist only of Units 1 – 6. The DNALC seeks to help students with content from Units 5 and 6, which pertain to molecular biology and genetics. Each week, we will hold structured AP® Bio Chats which will consist of a Q & A portion - with questions fielded from our Instagram @dna_learning_center as well as through our live video stream chat. A second portion of our chat will consist of an opportunity to practice free response-style questions complete with explanations.

Museum Tour: Ötzi the Iceman

Date: Thursday, April 9, 2020
Time: 3:00 p.m. (EDT)
Audience: AP® Biology students and educator

In the fall of 1991, two hikers in the Ötztal Alps discovered the mummified remains of a 5,300-year-old man. Now preserved in a climate-controlled freezer at the South Tyrol Museum of Archaeology in Italy, the mummy known as Ötzi the Iceman and his possessions provide a window into life in prehistoric Europe. Join Amanda McBrien at the DNA Learning Center to view the world’s first replica of Ötzi the Iceman and to see what Ötzi’s body, DNA, and belongings tell us about Neolithic people.

RNA-Seq with DNA Subway, Part I

Date: Friday, April 10, 2020
Time: 1:00 p.m. (EDT)
Audience: Undergraduate biology and up

RNA sequencing (RNA-Seq) is a widely used experimental approach in molecular biology. RNA-Seq allows us to measure the level of RNA in cells and tissues, and therefore make inferences about what genes are active, under what circumstances, and when. Since every cell’s copy of its genetic blueprint is the same, it is the timing and amount of gene expression—and subsequently the production of proteins—that differentiate cells by developmental time point and developmental fate Join Jason Williams for this three-part course to learn the basics of RNA-Seq and how to use the online platform DNA Subway to analyze an example data set.

Pollen Tells a Story

Date: Friday, April 10, 2020
Time: 3:00 p.m. (EDT)
Audience: Grades 5-8, and Ötzi enthusiasts

Discovered in the Italian Alps in 1991, the 5300-year-old mummy nicknamed Ötzi the Iceman has become an important source of information about the Neolithic. Still, there are many unanswered questions about his life and death. Join DNALC instructor Erin to discover how pollen in Ötzi’s digestive system was used as a forensic tool to create a timeline of where he may have been in the final 36 hours before his untimely demise.
