Researchers use flowing fluids to create mechanical stress needed for bone formation
Tissue engineering researchers in Rices J.W. Cox Laboratory for Biomedical Engineering have developed a new technique that allows bone-forming cells to build a porous, 3-D bony matrix thats structurally similar to natural bone. This photograph from an electron microscope shows a pore that has formed in a 3-D bony matrix. Bone-forming cells are clearly visible lining the walls.
A new study by Rice University researchers indicates that bioengineers growing bone in the laboratory may be able to create the mechanical stimulation needed to grow bone outside the body.
One of the greatest challenges tissue engineers face in growing bone in the laboratory is recreating the conditions that occur inside the body. The recipe for growing healthy bones includes not only a precise biological mix -- bone cells called "osteoblasts" and several growth factors that osteoblasts use to build the mineralized matrix of bones -- but also mechanical stimulation. Astronauts whose bones become brittle after months in orbit are a testament to the importance that mechanical stress plays in bone growth. In orbit, their skeletons arent subject to the everyday stresses of gravity.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
