Even in patients with advanced Alzheimer’s Disease, familiar music from long ago can awaken memories and prompt interactive behaviors. But how does that happen? A U.C. Davis researcher is working to unravel the neural mechanisms within the brain.

Much of the research that has been done so far on how music stimulates the brain has used musical samples that are not particularly stimulating. Dr. Petr Janata, associate professor of Psychology at the UC Davis Center for Mind and Brain, says that a new round of studies should work with recognizable samples, and could discover that the brain encodes different types of music in different ways or areas.

That’s one area of research that Janata hopes to explore himself, along with expanding the studies he’s done on Alzheimer’s patients to include different age groups.

Dr. Peter Janata will discuss his research into “Music, Memories and the Brain"  in a public presentation Friday, Feb. 19 at 8 pm in the Glaser Center in Santa Rosa, a benefit event for the Sonoma County Bach Society.

You can read more about research into the associations between music, memory and Alzheimer's Disease in this Wall Street Journal article.

It may take a lifetime to see the results, but students replanting a native oak forest near Glen Ellen are taking the long view.

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.

The modern idea of sustainability education in northern California is also finding a home in the schools of a small ancient culture nestled high in the Himalayas.

Zenobia Barlow is Executive Director of the  Center for Ecoliteracy in Berkeley. She is also a Fellow of the Post-Carbon Institute, which is based in Sebastopol. She is seen here with Bhutan's Prime Minister, Lyonchhen Jigmi Y. Thinley. Barlow co-founded the Center for Ecoliteracy 20 years ago, and while their principles are gaining ever wider acceptance, she still is often asked to define the term. Here’s her answer.

Under Bhutan’s governance model focused on promoting “gross national happiness,” there are four priorities:  (1) good governance; (2) environmental conservation and preservation; (3) preservation of their ancient Buddhist culture; and (4) a non-destructive economic development strategy. But Barlow observes that it has only been in recent years, as the county slowly opened itself to the west, that Bhutan’s culture and traditions faced any real threats to their preservation.
