Blood cells produced in human bone marrow can save the life of someone with leukemia, but only if the donor and patient are carefully matched. Jeana Moore is walking the length and breadth of the United States to round up more donors, and boost the odds that those matches can be made.

In addition to her one-to-one conversations, Jeana Moore is also actively working to set in motion plans for bone marrow drives in many of the communities she’s passing through.

She notes that they combine well with blood drives that may already be scheduled. Moore’s journey is also inspiring “sister” bone marrow drives in communities far from her pedestrian route.

Moore is just 900 miles—and four pairs of shoes—into her trek, but already she considers it an unqualified success.

To follow her progress, you can read Jeana's journal of her journey and see her planned itinerary, which are both featured on her website. Or go directly to  the National Bone Marrow donor registry to sign up or get more information.

Conflict doesn’t have to be violent. In fact, proactive non-violence can be used to force change, and those skills and tactics can be taught and practiced. That’s what Cynthia Boaz is doing at an international conference in India this week.

Cynthia Boaz, a Sonona State University professor of political science, has studied the mechanics and practices of non-violence, and is presenting on that subject this week at an international conference hosted by War Resisters International. All true and effective non-violent movements for change must first gain a measure of popular support within the repressed indigenous populations, she explains, then as the movment gains strength, the oppressor is left with nothing but force to try to sustain itself.

Ghandi and the Rev. Martin Luther King are often seen as exemplars of non-violent leadership, but Boaz says the high-profile charismatic individual at the head of a movement is atypical, and not necessarily the most effective model.

But just as grassroots leaders can study and learn the skills and tactics of nonviolence, Boaz observes that oppressors, too, can and do try to understand and deflect those efforts.

Earthquake researchers are turning to a new tool to help them quickly gauge the location and severity of newly occurring temblors—Twitter.

The USGS has developed a prototype application to search and capture Twitter feeds that make reference to earthquakes, according to Paul Earle, at the agency’s Earthquake Information Center in Colorado. But it’s still in the beta testing mode.

Longer term plans for making use of the quake-related tweets may include publishing maps showing where they originated, but Earle says that’s still well off into the future.

Still, as the graphic below shows, there is strong evidence already available to suggest that there will be plenty of content for the USGS program to work with as soon as it is fully operational.

Electrons move faster than earthquakes, giving new automated alert systems a few key seconds to warn outlying areas that some shaking is on the way.

This project is moving forward as quickly as possible, says Doug Given, but to be fully effective it requires the installation of many more sensors along the biggest known fault lines.

In setting all this up, priority has been given to the San Andreas Fault, one of the longest and most active in all of California.

The founding Fathers saw the U.S. Constitution as a dynamic document that would evolve and change over time. Writer and activist David Swanson believes we’re long overdue in getting to work on that.

In his new book, Daybreak:  Undoing the Imperial Presidency and Forming a More Perfect Union, Swanson tracks the gradual accretion of political powers in the office of the presidency—something that has been underway for most of our national history, but which accelerated markedly in the past eight years. In his analysis, that is dangerously undemocratic, but its hardly the only place in our national governance where that is a problem. Another is the U.S. Senate, particularly the convoluted procedural practice of the filibuster, which Swanson would like to see ended.

The calls for impeachment of Dick Cheney or George W. Bush or members of their administration have diminished over the past year, but Swanson notes that leaving office does not remove or even lessen their vulnerability to such charges. And he contends that pursuing impeachment against any of the potentially culpable former officials would serve the further purpose of reasserting the strength of the House of Representatives.

The politics of 2009 were sharply different from the years before, Swanson observes, as much of the activism that had mobilized against the wars in Iraq and Afghanistan got caught up in the Obama campaign, and has not yet re-established itself. He speculates that the anti-war effort might actually be more effective today if John McCain had been elected instead.

David Swanson will be speaking at the Glaser Center in Santa Rosa at 7 pm on Wednesday, Jan. 13, hosted by the Progressive Democrats of Sonoma County.
