What’s the News: A new thumbnail-sized microscope will give researchers a way to see what’s happening in the brain of a mouse as it moves around and goes about its business. The microscope, described earlier this week in Nature Methods, weighs less than 2 grams—little enough that it can be fitted atop a rodent’s head—and tracks the activity of up to 200 brain cells.
A neuroscientist who has spoken out in support of animal testing is in the news again after a militant animal rights group sent razor blades and a threatening note to his house. The group claims that the razor blades were contaminated with HIV-infected blood.
The researcher, J. David Jentsch, who studies addiction and schizophrenia at UCLA, explains the incident:
“About a week ago I was going through my mail in my kitchen and I opened a letter and razor blades spilled out on the floor. It was the first sign something was nefarious,” he said. “The letter inside contained quite specific and heinous acts of violence to kill me.” [CNN]
Jentsch made headlines last year when he staged a pro-test rally in support of (humane) animal research after an animal rights group fire-bombed his car in his driveway. The threats and harassment of Jentsch and other department employees have continued, but Jentsch seems undaunted and undeterred.
