More women than ever are going to college, and they are graduating in record numbers, too. Expect in certain subject areas, such as math and the hard sciences. A local group believes that the way to change that is to start early.

Expanding Your Horizons is not a job fair, but local board member Julie Silk says it does give the girls who participate a close-up look at some career possibilities they might not previously have considered.

The online registration form for the Sonoma County Expanding Your Horizons workshop at Sonoma State on March 20, is available here.

Keeping kids safe when they’re online isn’t about technology so much as trust and communication.

It’s a well-worn cliché that kids are often—maybe usually—more tech savvy than their parents. Petaluma-based tech guru Leo Laporte says the first step in open communication with teens about their adventures online is often helping Mom and Dad catch up.

But, he adds, getting a grip on the online landscape today is usually a short-lived accomplishment.

Leo Laporte and his family will present “Wired Families, Safe Kids—One Family’s Journey,” at Sonoma Academy at 6:30 pm on Thursday, March 4th.

Poisonings, both accidental and criminal, have been happening for centuries. But the science of investigating those deaths is barely a hundred years old.

As she began to research the history of forensic medicine in Jazz Age New York, science writer Deborah Blum, author of The Poisoner's Handbook,  says she was struck by the number and variety of toxic substances that were being used.

Many of those historic toxics are no longer in wide use, but that doesn’t mean we are any less vulnerable to poisons now, Blum (left) says. In fact, the chemistry of modern-day poisons is more complex than 90 years ago.

Forensic examinations and laboratory analyses have become central to a growing list of popular network television dramas. But Blum has no complaints about them.

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.
