| Genetically identical bacteria can behave in radically different ways Posted: 02 Jan 2014 11:20 AM PST When a bacterial cell divides into two daughter cells there can be an uneven distribution of certain survival mechanisms. The resulting cells can behave differently from each other, depending on which parts they received in the split. This is another way that cells within a population can diversify and enhance the odds that some members of a population of bacteria can avoid threats, such as antibiotics. |
| Animal cells can communicate by reaching out, touching, study shows Posted: 02 Jan 2014 11:20 AM PST In a finding that directly contradicts the standard biological model of animal cell communication, scientists have discovered that typical cells in animals have the ability to transmit and receive biological signals by making physical contact with each other, even at long distance. |
| International team completes systematic, genomic study of cervical cancer Posted: 26 Dec 2013 08:53 AM PST Researchers from the Boston area, Mexico, and Norway have completed a comprehensive genomic analysis of cervical cancer in two patient populations. The study identified recurrent genetic mutations not previously found in cervical cancer, including at least one for which targeted treatments have been approved for other forms of cancer. The findings also shed light on the role human papillomavirus plays in the development of cervical cancer. |
