Analyses of the similar bones to the fossils lead a leading physiologist to term the anthropological finding as farfetched speculation
The remains included a jawbone with teeth, hand bones and foot bones, fragments of arms, and a piece of collarbone. The remains also included a single toe bone; its form providing strong evidence that the pre-human creatures walked upright.
The discovery by two Ethiopian scholars, Yohannes Haile-Selassie, an anthropologist studyin
The marriage of machine and biology requires adopting the pliability and strength from the legs of this despised insect
The cockroach is an insect despised for its ubiquitousness, among other reasons. Yet, it may hold a key to the next evolutionary step in the “life” of robots.
Background
For years, serious futurists could only imagine that robots, such as the television model, would always be stiff, clumsy, and prone to breakdown. This was before the advent of “Biomimet
The peculiar behavior of high-temperature superconductors has baffled scientists for many years. Now, by imaging the copper-oxide plane in a cuprate superconductor for the first time, researchers at the University of Illinois at Urbana-Champaign have found several new pieces to this important puzzle.
As reported in the Aug. 19 issue of Physical Review Letters, physics professor Ali Yazdani, graduate student Shashank Misra, and colleagues used a scanning tunneling microscope to demonstrate t
When “frustrated” by their arrangement, magnetic atoms surrender their individuality, stop competing with their neighbors and then practice a group version of spin control—acting collectively to achieve local magnetic order—according to scientists from the Commerce Departments National Institute of Standards and Technology, Johns Hopkins University and Rutgers University writing in the Aug. 22, 2002, issue of the journal Nature.

Advance Should Speed Semiconductor Industry Search
Researchers from the Commerce Departments National Institute of Standards and Technology (NIST) reported today they have developed methods for characterizing key structural features of porous films being eyed as insulators for the ultrathin metal wires that will connect millions of devices on future microprocessors and increase processor speed. The advance, reported today at the American Chemical Societys national meeting
Using transplants of bone marrow cells improved the recovery from stroke in rat experiments, according to a study published in the August 27 issue of Neurology, the scientific journal of the American Academy of Neurology.
The rats treated with an intravenous transplant of adult human stromal cells (mature cells from bone marrow) had significant improvements in their ability to function 14 days after the stroke, compared to rats that did not receive transplants after a stroke.
