New findings on the formation of body pigment

(PhysOrg.com) -- The skin's pigment cells can be formed from completely different cells than has hitherto been thought, a new study from the Swedish medical university Karolinska Institutet shows. The results, which are published ...

Researchers pinpoint neural nanoblockers in carbon nanotubes

Carbon nanotubes hold many exciting possibilities, some of them in the realm of the human nervous system. Recent research has shown that carbon nanotubes may help regrow nerve tissue or ferry drugs used to repair damaged ...

Researchers find key to keeping cells in shape

(PhysOrg.com) -- Yale University researchers have discovered how a protein within most cell membranes helps maintain normal cell size, a breakthrough in basic biology that has implications for a variety of diseases such as ...

Researchers find new actions of neurochemicals (w/ Video)

(PhysOrg.com) -- Although the tiny roundworm Caenorhabditis elegans has only 302 neurons in its entire nervous system, studies of this simple animal have significantly advanced our understanding of human brain function because ...

New insight into primate eye evolution

Researchers comparing the fetal development of the eye of the owl monkey with that of the capuchin monkey have found that only a minor difference in the timing of cell proliferation can explain the multiple anatomical differences ...

How an enzyme tells stem cells which way to divide

Driving Miranda, a protein in fruit flies crucial to switch a stem cell's fate, is not as complex as biologists thought, according to University of Oregon biochemists. They've found that one enzyme (aPKC) stands alone and ...

To swim or to crawl: For the worm it's a no brainer (w/Video)

A study at the University of Leeds has shown, for the first time, that C. elegans worms crawl and swim using the same gait, overturning the widely accepted belief that these two behaviours are completely different.

Potential pathway for drug intervention

A newly identified molecular pathway that directs stem cells to produce glial cells yields insights into the neurobiology of Down's syndrome and a number of central nervous system disorders characterized by too many glial ...

Researchers identify a protein critical for memory, learning

Researchers from the University of Toronto and The Hospital for Sick Children (Sick Kids) have made a breakthrough discovery that may eventually change the way physicians approach treatment of learning and memory defects ...
