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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
