Bizarre walking bat has ancient heritage
...f 1,100 bat species worldwide that has a true four-legged walking gait when manoeuvring on the ground.
It uses its wings as forelegs. Its thumb and toe
claws have a unique extra talon for extra grip, plus a system of adhesive, gecko-like grooves in the soft, deeply wrinkled soles of its feet,

or dropped something on it) or a minor fungal infection that can be easily cleared up by a visit to the doctor."
Italy's geologic history becomes a personal tale in Walter Alvarez's new book
... Italy, he currently is working with graduate student David Shimabukuro to determine the relationship between the island of Sardinia and Calabria, the toe
of the Italian boot, which has moved southeastward over the millennia to open up the Tyrrhenian Sea.
Just as his book displays a deep interest in t...
'A dinosaur dance floor'
...o a single rock bed.
Four different kinds of footprint shapes are seen repeatedly in 14 percent of the impressions, and they include obvious claw, toe
and heel marks. The other impressions "are clearly similar."
One-third of the prints are surrounded by small ridges or mounds. Such features would...

When threatened, a few African frogs can morph toes into claws
... free-floating bones at their tips. Eventually he determined that these small nodules at the tips of the frogs' feet were connected to the rest of the toe
by a collagen-rich sheath.
"These nodules are also closely connected to the surrounding skin by dense networks of collagen," Blackburn says. "It ap...
Mysterious mountain dino may be a new species
...at the University of Alberta. "It's very distinct from other dinosaurs that were found at the same time in southern Alberta."
The seven shin, arm, toe
and possible skull bones were found nestled in a dip between mountains in the Skeena range, and while the fragments resemble those from a small two-le...
New family of gecko discovered by researchers from the U of Minnesota and Villanova University
... Researchers are also interested in the gecko because of the animals sticky toe
pads, which allow them to scale rough and smooth surfaces -- a characterist...y tree that, in turn, will allow scientists to better understand how sticky toe
pads have evolved.
The researchers have named the new family Phyllodacty...
Wisconsin researchers describe how digits grow

bones, arise not from cartilage cells but from mesenchymal cells. And they discovered that a complex array of signals from a variety of genes at diffe...

Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
During Stage 1, drill targets are 1) the incoming sediment of Shikoku Basin and the underlying oceanic crust, 2) the frontal thrust system at the toe
of the accretionary wedge (where sediment is added to tectonic plates through frictional contact), 3) the mid-wedge multiple-fault system (mega-splays...
'Terror bird' arrived in North America before land bridge, study finds
...error bird was carnivorous, weighed about 330 pounds, had powerful feet and a head larger than a man's. It is known in the fossil record from a single toe

Wisconsin scientists grow critical nerve cells
Motor neurons transmit messages from the brain and spinal cord, dictating almost every movement in the body from the wiggling of a toe
