Implications for treatment of birth defects, wounds, cancer The genetic pathway that regulates the way cells align themselves relative to each other has been found to act as a "stop sign" that signals organisms when to halt cell growth, according to new research published by biologists at the Center for Regenerative and Developmental Biology in Tufts University's School of Arts and Sciences. The research sheds light on one of the primary challenges to developing new ways to induce...

A team of researchers at Tufts University's School of Arts and Sciences and School of Engineering have discovered that individual atoms can catalyze industrially important chemical reactions such as the hydrogenation of acetylene, offering potentially significant economic and environmental benefits. Hydrogenation — the addition of hydrogen atoms to an organic compound — is critical to the food, petrochemical and pharmaceutical industries. Hydrogenation requires the presence of...

Researchers have combined bioactive peptides to successfully stimulate wound healing. The in vitro and in vivo study, published today in PLoS ONE, demonstrates that the combination of two peptides stimulates the growth of blood vessels and promotes re-growth of tissue. Further development of these peptides could lead to a new treatment for chronic and acute wounds. The team tested a newly-created peptide, UN3, in pre-clinical models aimed to simulate impaired wound healing as is seen in...

New research demonstrates that previous models used to examine cancer may not be complex enough to accurately mimic the true cancer environment. Using oral cancer cells in a three-dimensional model of lab-made tissue that mimics the lining of the oral cavity, the researchers found that the tissue surrounding cancer cells can epigenetically mediate, or temporarily trigger, the expression or suppression of a cell adhesion protein associated with the progression of cancer. These new findings...

Changes In Bioelectric Signals Cause Tadpoles To Grow Eyes In Back, Tail
2011-12-09 03:55:59

For the first time, scientists have altered natural bioelectrical communication among cells to directly specify the type of new organ to be created at a particular location within a vertebrate organism. Using genetic manipulation of membrane voltage in Xenopus (frog) embryos, biologists at Tufts University's School of Arts and Sciences were able to cause tadpoles to grow eyes outside of the head area. The researchers achieved most surprising results when they manipulated membrane voltage...

New Species Of Fungus Found In A Wasp Nest
2011-11-10 04:29:58

Mucor nidicola species previously unknown to science While some researchers look for new species in such exotic places as the deep sea, tropical regions, or extreme environments, a team headed by Tufts researchers turned their attention towards nests of an invasive paper wasp. What they found was a new species of fungus. Philip T. Starks, associate professor of biology at the School of Arts and Sciences at Tufts University, and doctoral student Anne A. Madden published their discovery...


Word of the Day
grass-comber
  • A landsman who is making his first voyage at sea; a novice who enters naval service from rural life.
According to the OED, a grass-comber is also 'a sailor's term for one who has been a farm-labourer.'
