Gapless Telomere to Telomere human genome (T2T-CHM13) now available
On April 1, 2022, Science published the first complete sequence of a human genome, known as T2T-CHM13. This notable scientific achievement comes two decades after the first human genome release from the Human Genome Project and offers an in situ look at biologically important regions, such as centromeres, telomeres, and segmental duplications, that were previously … Continue reading Gapless Telomere to Telomere human genome (T2T-CHM13) now available

Please Join Us in Honoring Milton Corn, MD
This blog post is based on remarks given at the May 17 Milton Corn Memorial Concert. Yesterday, I was honored to join in a beautiful celebration for the life of Dr. Milton Corn, an amazing man who I regarded as my adviser, colleague, and—most importantly—my friend. I would like to thank his wife Gilan and … Continue reading "Please Join Us in Honoring Milton Corn, MD"
