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...

Camille DeSisto Searches for Answers in What Lemurs Leave Behind

May 18, 2019
Undergraduate IB Concentrator, Camille DeSisto (Davis Lab) spent two summers in Madagascar’s tropical forests studying invasive plant dispersal, by exploring lemur poop. The island’s lemurs eat the plant’s fruit and poop out the seeds, widely spreading the invasive strawberry guava along Madagascar’s tropical east coast threatening native plants that are unlike plants found anywhere else. Camille's research was featured in the... Read more about Camille DeSisto Searches for Answers in What Lemurs Leave Behind
