Groundbreaking research reveals clues to the formation of hearts, intestines and other key organs

10.08.2011
How do the intestines in tiny birds or large mammals form intricate looping patterns? How do hearts and vascular systems form? Why do some large dog breeds succumb to gastric torsion while others don't? Newly released research co-authored by a Cornell University assistant professor provides some key clues to these natural phenomena.

"This research gives us hints to looping morphogenesis, how organs form from a single tube to the rotating structure of intestines," said Natasza Kurpios, assistant professor of Molecular Medicine at the College of Veterinary Medicine at Cornell. Kurpios co-authored the study, "On the growth and form of the gut" in the current issue of Nature. Her co-authors are Thierry Savin, Amy E. Shyer, Patricial Florescu, Haiyi Liang, L. Mahadevan and Clifford J. Tabin, all of Harvard Medical School and Harvard University.

Kurpios and her co-authors developed a model that mimics how developing intestines in vertebrates form the characteristic looped pattern in the body cavity. That model not only provides a template for organ asymmetry; it also could lead to better diagnosis of veterinary and human maladies such as malrotation of the intestines in babies and gastric torsion in large-breed dogs such as Labrador retrievers. "By understanding the patterns of loops, we could better identify and more accurately diagnose these conditions," Kurpios said. "This also gives us hints to the formation of other organs, such as the heart and the vascular system."

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
