Opening and closing the genome
02-22-2007 · EurekAlert!A dynamic cast of gatekeeper enzymes controls access to the DNA for gene transcription, adding and removing particular molecules to open or close the genome as needed. Researchers have identified an important new player in this gene-control system, an enzyme responsible for removing certain molecules, or marks, involved in opening or closing chromatin, the material that makes up chromosomes. The activity of this enzyme is thought to be widespread, likely affecting many genes.

- Tobacco companies admit their products cause cancer, but not in those who sue them
11-27-2006 · EurekAlert!
Despite publicly admitting, to varying degrees, that cigarette smoking causes cancer, the industry has consistently dismissed these claims for people who have sued them, reveals an analysis of recent lawsuits, published in a supplement to Tobacco Control.The authors looked at the opening and closing statements of the defense, witness statements and depositions for 34 personal-injury claims brought against major tobacco manufacturers between 1986 and 2003 in the US.

- MCA backs closure of Arctic waters
06-12-2007 · EurekAlert!
The Marine Conservation Alliance supports action today by the North Pacific Fishery Management Council to close all federal waters north of the Bering Strait to commercial fishing until a management plan, including habitat protection, is fully developed."Climate change is having a significant effect on the Arctic, opening previously ice-covered waters and drawing cold water species further north," said MCA's Dave Benton. "The council is right to look at closing these waters as a precautionary measure."

- Revolution in understanding of ion channel regulation
01-30-2008 · EurekAlert!
A study at Rush University Medical Center in Chicago published this week in the online version of Biophysical Journal proposes that bubbles may control the opening and closing of ion channels. This new understanding of the channels that control much of life in health and disease provides a vital piece of the molecular puzzle.

- Rapid Sea Level Rise in the Arctic Ocean May Alter Views of Human Migration
10-11-2006 · Woods Hole Oceanographic Institution (WHOI)
Scientists have found new evidence that the Bering Strait near Alaska
flooded into the Arctic Ocean about 11,000 years ago, about 1,000 years
earlier than widely believed, closing off the land bridge thought to be
the major route for human migration from Asia to the Americas.

- Researchers Find Smallest Cellular Genome
10-14-2006 · ScienceDaily
The smallest collection of genes ever found for a cellular organism comes from tiny symbiotic bacteria that live inside special cells inside a small insect. Just 182 genes, the 160-kilobase genome could revise ideas about what's needed for a cell to work. The finding also provides new insight into bacterial evolution.

- Phoenix rising: Scientists resuscitate a 5 million-year-old retrovirus
10-30-2006 · EurekAlert!
A team of scientists has reconstructed the DNA sequence of a 5-million-year-old retrovirus and shown that it is able to produce infectious particles. The retrovirus -- named Phoenix -- is the ancestor of a large family of mobile DNA elements, some of which may play a role in cancer. The study is the first to generate an infectious retrovirus from a mobile element in the human genome. The findings are reported in Genome Research.

- Study links attempted suicide with genetic evidence identified in previous suicide research
02-19-2007 · EurekAlert!
A Johns Hopkins-led study has found evidence that a genetic tendency toward suicide has been linked to a particular area of the genome on chromosome 2 that has been implicated in two additional recent studies of attempted suicide.

- New science of metagenomics 'will transform modern microbiology'
03-27-2007 · EurekAlert!
The emerging field of metagenomics, where the DNA of entire communities of microbes is studied simultaneously, presents the greatest opportunity -- perhaps since the invention of the microscope -- to revolutionize understanding of the microbial world, says a new report from the National Research Council. The report calls for a new Global Metagenomics Initiative to drive advances in the field in the same way that the Human Genome Project advanced the mapping of our genetic code.
