New biomaterials improve medical devices

... with topics such as designing a protein matrix to imitate the natural one that cells interact with, exploiting nature's tricks to alter biomaterial surfaces, and biofilms that cause infection of implants. Some of the new approaches to these challenges employ nanotechnology methods for both diagnostic and i...

...le's actions, and may also help in learning how to imitate them. Professor Patrick Haggard of UCL's Institute of Cognitive Neuroscience says: "We've shown that the mirror system is finely tuned to an individual's skills.

Elephants imitate sounds as a form of social communication

Elephants learn to imitate sounds that are not typical of their species, the first known example after humans of vocal learning in a non-primate terrestrial mammal. The discovery, reported in today's Nature, further supports the idea that vocal learning is important for mainta...

Autism linked to mirror neuron dysfunction

...rocesses language, for instance, or being able to imitate and learn from others' actions, or decode their intentions and empathize with their pain. Because autism is characterized, in part, by deficits in exactly these sorts of social interaction and communication skills, previous research has suggested th...

European funding for research on biomolecular nanomachines

...nched on May 1, 2005. Biomimetic systems mimic or imitate certain aspects of biological systems. One astounding aspect of biological cells is their ability to undergo dramatic morphological transformations: they can adapt their shape in order to squeeze themselves through very narrow pores, they can extend ...

Certolizumab pegol demonstrates positive results in two Phase III Crohn's disease trials

...gnose Crohn' TM s disease and because it can often imitate other gastroenterological conditions, patients may experience a lengthy diagnosis process. Although Crohn' TM s disease affects males and females equally of all ages, the most affected in the U.S. are 20-29 year olds and 30-39 year olds . The dise...

"New members of the sanctioning institution punish because it is common to do so," said Rockenbach.

We decided to examine what this does to human cells." To test the effect of dual-particle irradiation, Sutherland's team a...

In addition, females were known to prefer males that had been trained to produce calls similar to theirs. The current study is important because it shows that female budgerigars preferentially pair with...
