Insects and mammals share common fat-building pathway, study suggests

...things tend to happen almost across the board--our bones become thinner and we gain fat," said senior autho...o reverse or prevent this trend, building stronger bones while reducing fat." The researchers found that flies in which the Hh pathway in the fat bodies was...

Robot assisted surgery more accurate than conventional surgery

...f the robotically assisted operations lined up the bones to within two degrees of the planned position, but only 40 percent of the conventionally performed cases achieved this level of accuracy. The team found there were no additional side effects from using robot assisted surgery, and recovery from surge...

Bioactive cement scaffold may improve bone grafts

...mplants that may improve construction or repair of bones in the face, skull and jaw, has been developed by researchers from the American Dental Association Foundation (ADAF) and the National Institute of Standards and Technology (NIST). Described in recent and upcoming journal articles,* the new technolo...

FSU biologist says new dinosaur is oldest cousin of Tyrannosaurus rex

Wisconsin scientists find a way to make human collagen in the lab

...rotein in the body, reinforcing connective tissue, bones and teeth, and forming long, fibrous cables to strengthen tendons. Collagen forms sheets of tissue that support the skin and every internal organ. There is nothing in the body, in fact, that does not depend in some way on collagen. In medicine, coll...

NJIT engineer poised to take stem cell research a step forward

...ients suffering from osteoporosis, whose fractured bones could be regenerated by the cells. Arinzeh has pushed the basic science of stem cells forward and, with her latest two grants, she is poised to take it yet another step. "Treena has all the earmarks of a technical superstar," says Jaffe, her partn...

Ancient DNA provides clues to the evolution of social behavior

...rder and regurgitated pellets of indigestible fur, bones and teeth while they rest. From these teeth, scientists can determine which rodent species lived in a roughly 3-mile radius of the cave at any given time. Using modern and ancient DNA from tuco-tuco teeth found in the two caves, Stanford graduate st...

...nd tibia and absorb the compressive shock that the bones undergo during walking and running. Over the past 18 months, he and his students Adam Aufderheide and Gwen Hoben have perfected methods of growing meniscus-shaped pieces of cartilage, but they are still trying to perfect the mechanical strength of th...

Stem cells from muscles can repair cartilage

...rticular cartilage (cartilage covering the ends of bones where they meet in a joint) frequently occurs due to injury or illness, and can lead to degenerative disease. Treatments and experimental approaches to repair this articular cartilage have achieved limited results, but currently there is no method to...
