In Memory of Samantha Lin '16

August 6, 2019
It is with great sadness that we report the death of OEB undergraduate alum Samantha (Sam) Lin '16. Sam was a wonderful student and a hugely valued member of the OEB community. From Harvard, she went on to Veterinary School at North Carolina State University, where she was due to graduate next year. Our thoughts are with Sam's family and friends, and with the many OEB-ers affected by this awful tragedy.... Read more about In Memory of Samantha Lin '16

How Smooth Is A Dolphin?

July 17, 2019

Dolphin skin has long inspired research on drag reduction mechanisms due to the presence of skin ridges that could reduce fluid resistance. Prof. George Lauder and PhD student, Dylan Wainwright (Lauder Lab) collected in vivo three-dimensional surface data on the skin from five species of odontocetes (cetaceans that includes dolphins, porpoises, and all other whales possessing teeth) to quantitatively examine skin texture, including the presence and size of ridges.

Lauder, Wainwright and team molded the skin of live...

Overturning Evolutionary Doctrine

July 3, 2019

In a new study in Nature, Cassandra Extavour and her lab disprove an old hypothesis and prove a new one. Extavour says insects make up 80 percent of all animal species on Earth. She and PhD students, Sam Church, Seth Donoughe ('18), and Bruno de Medeiros analyzed a large data set to challenge the untested assumptions about egg size in insects. Across all insects, the team found...

From One Animal to an Ecosystem

June 21, 2019

At 45 pounds and just over two feet tall, adult European roe deer are much smaller than American deer and closer in size to a greyhound. And unlike their cousin species, red deer or elk, roe deer like to be solitary, spending most of their lives within a range of one square kilometer.  PhD student, Nathan Ranc (Paul Moorcroft lab) want to know the reason for this mystery. In the Alps of northern Italy, Nathan and colleagues are trying to build a model that explains the factors determining why particular deer choose to live where they do. His work with roe deer...

Oxygen Shapes Arms and Legs

June 13, 2019

A collaboration between professors at Tokyo Tech and Yamagata University and Prof. Jim Hanken has identified a surprising factor that the amount of oxygen surrounding the embryo could have been crucial for the appearance of interdigital cell death in tetrapods during evolution. The study, published in Developmental Cell, looked to understand the role of environmental oxygen in the...
