"Fat makes extra hormones, which lead to extra cell activity and extra abnormal cell activity, " she said.
CNN: Cancer death rate dropped nearly 20 percent in 15 years
The idea that more brain cell activity could lead to more amyloid-beta build up is an exciting, if sobering, finding.
FORBES: Wandering into Alzheimer's: Could Your Thoughts Reduce Your Risk?
The hope was that this would restore brain cell activity in the thalamus, a relay station that integrates input from many parts of the brain, helping make consciousness possible.
When it comes to people, said Dr. Hsieh, it might be similarly effective to give the therapy in the first week after a heart attack, when stem-cell activity is highest.
In particular, low-status individuals showed high levels of activity in genes associated with the production of various immune-related cells and chemical signalling factors, as well as those to do with inflammation (a general immune response that involves tissue swelling and increased immune-cell activity in the affected area).
Then, he needed two hours of computer time to calculate a single cell's activity during a fraction of a millisecond.
He was able to get in touch with his wife and son and daughter while in the car driving to his Maryland home, but it was difficult because of all the cell-phone activity.
Murray's credit cards and cell phone have not registered any activity since the night she disappeared, February 9, 2004.
According to a study from the National Institutes of Health, cell phones may alter your brain activity, and it could be potentially damaging in the long term.
They categorised facial dimensions such as the distance between the eyes, then recorded the electrical activity of one brain cell at a time while they showed cartoons to the macaques.
The effect of increased brain activity in children because of cell phone radiation is another area yet to be studied.
But, police say, there was no activity on Kopetsky's cell phone after she walked out of school, indicating that the battery went dead or was removed from the phone.
The findings of the study, which examined the subjects during just one 50-minute exposure, raise a key question, the researchers said: What, if any, are the long-term consequences of repeated increased brain activity due to exposure to cell phone radiation?
Once they'd arrested the suspect, they searched his cell phone and found evidence indicating possible drug trafficking activity that was unrelated to the original arrest premise.
It is also suspected that brain cell death in Parkinson's patients is caused by over-activity of another brain chemical called glutamate.
Researchers made all 9, 000 and tested them for biological activity, using automated robots to mix them with various cell types to see their effects.
They do this by interfering with the activity of the messenger RNA strands that transfer genetic information from the cell's nucleus to its protein-making machinery.
And the machines can only test for one event at a time--say, monitoring one enzyme's activity or seeing if a compound binds to a target on a cell.
The new Brain Activity Map project hopes to understand and classify every signal from every cell in our grey matter, identifying where everything from thoughts, feelings and inspiration originate -- at a level beyond anything currently underway.
It is also backed up by work done on both people and laboratory animals, which shows that stress changes the activity of neurotransmitters, the chemicals that carry signals from one nerve cell to another in the brain.
Researchers can only use dead cells or pieces of a cell and can only test for one response at a time, such as enzyme activity or the binding of a compound to a receptor.
This detects the activity of genes by measuring the presence of the molecular messengers they send into the cell to do their bidding.
ECONOMIST: Brain development may be influenced by genetic parasites
After gathering enough evidence to get a court order to investigate Kruse Wellwood, 16, and Cameron Moffat, 17, police bugged their homes, monitored their cell phones, and performed forensic analysis of their computers and phones for a history of their Internet activity and online and text conversations.
FORBES: Solving A Teen Murder By Following A Trail of Digital Evidence
High activity levels of a third gene, CHI3L1 were common in cancers showing a larger degree of cell death.
This will be useful because the location and activity of receptor proteins on surface membranes can be a matter of life and death for a cell or a virus.
