Any devoted reader of the Rodent of the Week knows by now how much science depends on our furry friends. Without them, we would know next to nothing. That's why this week's news of a better way to study rats' brains deserves notice. Researchers reported they have developed a wearable, portable PET scanner that will measure the rodent brain function while the animals are awake and moving. The device was developed by scientists from the U.S. Department of Energy's Brookhaven National Laboratory, Stony Brook University.

Steady exposure to the electromagnetic radiation given off by cellphones during use may disrupt fetal development, disturb memory and weaken the barrier that protects the brain from environmental toxins, says a welter of new research being presented this week in Istanbul, Turkey. The authors of the studies, published in the past two years, highly preliminary and conducted on rabbits, mice and rats, suggested that the non-ionizing radiation emitted by cellphones and the base stations that broadcast cellphone signals may fundamentally damage cells by means other than the heat that they generate.

Proposition 37, the ballot measure mandating the labeling of genetically modified food that is also known as the "right to know" initiative, is narrowly running ahead of the opposition, according to the latest opinion polls. But even if the measure goes down - and it's the target of a $35-million publicity attack by agricultural and food industry interests - the campaign behind it will mark an important milestone in politics: the deployment of weapons-grade junk science. Of course, ignorance and anti-intellectualism are not new phenomena in our elections, nor in the political processes of other lands, dictatorships and democracies alike.

High-speed MRI scans produce effects in rats similar to those of antidepressants, confirming observations made in humans, Harvard University researchers said Thursday in the journal Biological Psychiatry. When repeatedly stressed, rats develop helpless behavior, which may be their version of despair, the researchers said. But in the experiment, the rats that had been exposed to magnetic fields showed less helplessness. "They behaved as if they had received an antidepressant," said Dr.

Rats have eaten food, nested in cabinets and multiplied in about 50 of 197 apartments at UC Santa Cruz's family student housing complex. The cause is unclear, but a fox family has disappeared from the area, some killed by rat poison, said grounds supervisor Rich Berger.

Scientists plan to use satellite photos to count giant kangaroo rats, the first-ever monitoring of an endangered species from outer space. Biologists will examine the images to find the circular patches of earth denuded by the rats as they gather food around their burrows. From that they plan to get the first accurate population count of the rodents, a bellwether for the health of a parched plains environment.The Nature Conservancy study is focusing on the vast Carrizo Plain in California's Central Valley.

Rats and their droppings continue to turn up at a Los Angeles County coroner's crypt, which one worker attributes to an ongoing problem but the county says are merely leftover signs of a past infestation. "To my knowledge, there have been no live rats found inside the crypt this week," said coroner's spokesman Craig Harvey. He acknowledged that dead rats have been found.

Rats wired to record brain activity raced around a twisted track aboard the space shuttle Columbia in an experiment that could help Alzheimer's patients. In the experiment by Bruce McNaughton, a psychologist from the University of Arizona, four male rats--their claws clinging to Velcro in the absence of gravity-- were to find their way around two tracks in Columbia's neurological laboratory.

Treatment with genetically modified stem cells helped rats with a paralyzing disease live significantly longer, U.S. researchers said this week. Rats with amyotrophic lateral sclerosis, or Lou Gehrig's disease, that were treated with the gene-engineered stem cells lived 28 days longer than untreated mice, the researchers told a conference. The injection contained adult nerve stem cells that were engineered to release a growth factor called glial cell-line derived neurotrophic factor, or GDNF.

The usual crush of people who have business in the prefab complex of Van Nuys Municipal Court had long since dispersed one evening last week when the Apartment Assn. of San Fernando Valley and Ventura County assembled in Division 114 to hold a trial of its own. The association rented the courtroom Wednesday night for its regular meeting. This month's topic was eviction.
