Researchers at UT Southwestern Medical Center at Dallas have discovered a protein that controls an early and significant step in the exquisitely timed process of bone formation.
Dr. Eric Olson, chairman of molecular biology, and colleagues have shown the protein HDAC4 to be essential for proper bone development, or osteogenesis. Their findings, reported in the November issue of the journal Cell and available online, may have widespread implications for understanding and preventing osteoporosis or other bone disorders, said Dr. Olson, senior author of the study.
"This was a very unexpected discovery. We were studying the role of the HDAC4 gene in the control of heart growth. When we created genetically modified mice lacking the HDAC4 gene, we found that they had excess bone and died because their cartilage was converted into bone," said Dr. Olson, who directs the Nancy B. and Jake L. Hamon Center for Basic Research in Cancer and the Nearburg Family Center for Basic Research in Pediatric Oncology.

Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
