MicroCT Reveals Detailed Head Morphology of Arthropod, Leanchoilia illecebrosa

June 25, 2020

Javier Ortega-Hernández and Yu Liu, Professor of Paleobiology, Yunnan University, China have collaborated for years in the study of Chengjiang arthropods and their evolutionary significance. Their latest paper in Current Biology shows with unprecedented clarity the head morphology of the species Leanchoilia illecebrosa - a member of...

Study Supports Key Insights into Fish Locomotion

June 8, 2020

Fish locomotion is characterized by waves of muscle electrical activity that proceed from head to tail, and result in an undulatory pattern of body bending that generates thrust during locomotion. However, isolating and studying these movements in live fishes is difficult and scientists often use robotic models instead. Most robotic fish models are either passive, flapping models that are simple but don't actively swim, or active, hard models that actively swim but take forever to construct. PhD candidate ...

MicroCT Reveals New Arthropod Species

June 1, 2020

Using microCT Javier Ortega-Hernández and Yu Liu, Professor of Paleobiology, Yunnan University, China discovered Xiaocaris luoi, a new species of fuxianhuiid, an important group of early branching arthropods that are central to discussions concerning the early evolution of this phylum. Xiaocaris luoi, represents the smallest known fuxianhuiid, its trunk legs bore strong spines...

Study Aids in Understanding How Leaf Carbon Transport in Mature Trees Aids in Water Stress

June 1, 2020

Trees typically experience mid-day water depressions due to water evaporating out of the plant's stomata (a tiny opening or pore in plant leaves that intakes carbon dioxide, which is needed for photosynthesis). To understand how the water stress influences carbon's movement from the leaves (where production begins) to the roots, trunk and shoots (where the water is needed), PhD candidate Jessica Gersony (Holbrook Lab) measured carbon and water traits of five mature red oak trees over the course of 24 hours at Harvard Forest.
