Clue to fracture treatment in mice
Clue to fracture treatment in mice
A naturally occurring protein may hold the key to treatments for osteoporosis, University of Sydney researchers have reported in this month's Journal of Bone and Mineral Research , the official journal of the American Society for Bone and Mineral Research. The announcement follows more than a decade of research into interferon gamma, a protein which is produced by the body's immune system and stem cells and that is also used as a treatment for hepatitis C in humans.

Probing Question: What causes stuttering?
By Grace Warren Research Penn State In the movie "A Fish Called Wanda," he's the guy who bungles the old lady's murder. In "My Cousin Vinny," he's the inept public defender for the accused. People who stutter are so often portrayed in popular media as either incompetent or disturbed that even they find themselves wondering what's wrong with them.

Leafcutter ant genome reveals secrets of fungus farming ways
Leafcutter ant genome reveals secrets of fungus farming ways
Leafcutter ants, signature denizens of New World tropical forests, are unique in their ability to harvest fresh leaves to cultivate a nutrient-rich fungus as food. Leafcutter ants scurry with their harvest of leaves, which they use to fuel huge underground fungus farms. (Video courtesy: College of Agricultural and Life Sciences) Now, this mutualism — a complicated interplay of ants, fungi and a suite of bacteria — is coming into sharper focus as a team of UW-Madison researchers has published the complete genome of the leafcutter ant, Atta cephalotes.

Mystery of how fleas jump resolved
Mystery of how fleas jump resolved
New research from the University of Cambridge sheds light on how fleas jump, reaching speeds as fast as 1.9 meters per second. In 1967, a scientist by the name of Henry Bennet-Clark discovered that fleas store the energy needed to catapult themselves into the air in a pad made of the unique 'elastic' protein resilin.

Simple marine worms distantly related to humans
Two groups of lowly marine worms are related to complex species including vertebrates (such as humans) and starfish, according to new research. Previously thought to be an evolutionary link between simple animals such as jellyfish and the rest of animal life - the worms? surprising promotion implies that they have not always been as simple as they now appear.

Researchers ID molecular links vital for cell growth
Researchers ID molecular links vital for cell growth
When a cell is preparing to grow or replicate, it starts the way a monarch planning to expand his territory might: by identifying and marshaling the necessary resources, loading them onto the appropriate vehicles, and transporting them to the front line. For cells, that means connecting key molecules with so-called motor proteins, which are neatly equipped to recognize them and carry them to their designated positions at the intended site of growth.
