Human brains, in and out of skulls, promise to unravel Alzheimer’s mysteries

Human brains, in and out of skulls, promise to unravel Alzheimer’s mysteries

Why do some brains remain robust as time marches on, while others wither? What can be done to halt deterioration in its tracks, or even better — reverse it?
That’s the mystery that decades of work at UCI and other federal research centers are dedicated to unraveling. Some of the biggest brains in science are devoted to understanding aging, dementia and Alzheimer’s disease.

The secret life of bumblebees

Bees that build microbreweries, ride a miniature merry-go-round and possibly even wear diapers. In biologist Tobin Hammer’s UCI lab, all sorts of unusual projects unfold.

In searching for the genetic mechanism behind this difference, the UCI biologists selected as their subject Heliconius charithonia, in which visual capacity is sexually dimorphic. When they finished assembling the first complete genome for this species, they learned that its W – or female – chromosome contained the opsin gene.

Sweet smell of success: Simple fragrance method produces major memory boost

Sweet smell of success: Simple fragrance method produces major memory boost

When a fragrance wafted through the bedrooms of older adults for two hours every night for six months, memories skyrocketed. Participants in this study by University of California, Irvine neuroscientists reaped a 226% increase in cognitive capacity compared to the control group. The researchers say the finding transforms the long-known tie between smell and memory into an easy, non-invasive technique for strengthening memory and potentially deterring dementia.
