UCLA/Toronto researchers unlock key to memory storage in brain

...to healthy cells and away from sick cells in dying regions of the brain." Our memories define who we are, so learning how the brain stores memory is fundamental to understanding what it is to be human, Silva observed. "A memory is not a static snapshot," he said. "Memories serve a purpose. They are a...

The findings could have significant implications in microbiology and virology research, as the rhesus macaque is widely used as a model organism for studying immune response to viral infections, like...

Researchers associate calories from newspaper dessert recipes with community obesity rates

...consin Medical Journal (Volume 106, No. 2). The regions studied were in the West (Los Angeles, Denver, Portland), Midwest (Milwaukee, Detroit, Kansas City), South (Washington D.C., Dallas, Jacksonville) and the Northeast (New York, Philadelphia, Boston). "The average total caloric content of dessert re...

Major genetic study identifies clearest link yet to obesity risk

The study found that people carrying one copy of the FTO allele have a 30% increased risk of being obese compared to a person with no copies. However, a person carrying two copies of the allele has a 70% increased risk of b...

Macaque genome analysis will help find human disease genes

Need oxygen? Cells know how to spend and save

...the COX-swapping. By examining the gene control regions of COX4, they found that the HIF-1 sensor switched on COX4-2 activity when oxygen is low. And they learned that because COX4-1 already is in the mitochondria, the swap for COX4-2 occurs when the sensor turns on yet another gene that produces an enzym...
