Cambrian Ancestor of Crustaceans and Insects in 3D

January 7, 2019

The pancrustaceans are the most diverse animal group to ever exist, and include familiar kinds of arthropods such as crustaceans (e.g. shrimp, crabs, lobsters) and six-legged insects. A new study by Prof. Javier Ortega-Hernández and Joanna Wolfe (Research Associate, Ortega-Hernández Lab), in collaboration with colleagues at Yunnan University in Kunming, illuminate details on the evolution of these successful invertebrates. The findings, published in the...

Researchers Look to Echidnas to Shed Light on Forelimb Evolution in Mammals

November 14, 2018

Mammals use their forelimbs for many activities including swimming, jumping, flying, climbing and digging. But how they evolved to do so is a mystery for scientists. Postdoc, Sophie Regnault (S. Pierce Lab) and Prof. Stephanie Pierce studied a highly-detailed musculoskeletal model of an echidna forelimb to shed light on how extinct mammals might have used their forelimbs. Echidnas are egg-laying mammals with many anatomical features in common with earlier mammal ancestors and can help bridge the gap between extinct and other...

Pesticide Exposure Disrupts Bumblebee Nest Behavior

November 9, 2018

Postdoc, James Crall joined former PhD student, Callin Switzer ('17, Hopkins Lab) and OEB professors, Benjamin de Bivort and Naomi Pierce to investigate the effects of neonicotinoid pesticides on the bumblebee's nest behavior. Previous studies showed the pesticides reduced colony size, but how the reduction occurred was not known. In their study published in Science...

What Makes a Mammal a Mammal? Our Spine!

September 21, 2018

A new study led by postdoctoral researcher, Katrina Jones (S. Pierce Lab) and Stephanie Pierce suggests the makeup of a spine is one more characteristic that defines a mammal. The research, published in the September 21 issue of Science, shows mammal backbones are different than the vertebra of most four-legged animals in that it is made up of different sections - neck, thorax, and lower back - that take on different shapes and...

How Clumps of Honeybees Survive Wind

September 17, 2018

L. Mahadevan and PhD students, Jacob Peters ('18) and Mary Salcedo (Mahadevan Lab) teamed with Prof. Orit Peleg, Colorado University-Boulder, to research the collective mechanical adaptation in honeybee swarms. The study, published in Nature Physics, shows the swarm of bees act as a superorganism that responds to physical stress by changing shape. Using both physical experiments and computer modeling, the team showed that the inverted cone...
