POPSDon't Stress! Bacterial Cell's 'Crisis Command Center' Revealed If a bacteria cell finds itself in a dangerous situation - for example, if the temperature or saltiness of the bacteria's environment reach dangerous levels which threaten the survival of the bacteria -a warning signal from the cell's surface is transmitted into the cell. Using cutting edge electron microscopy imaging techniques the authors of the new research observed that the stressosomes receive this warning signal, and in response several proteins called RSBT break away from the large stressosome. This breakaway triggers a cascade of signals within the cell which results in over 150 proteins being produced - proteins which enable the cell to adapt, react and survive in its new environment.

POPSgo out to vote this November 2008 Election year, to make your decisions not just based on issues sta I encourage all those within the community, who go out to vote this November 2008 Election year, to make your decisions not just based on issues stances but also on consistent character, virtue and temperament. Look for the candidates that do not make the popular decision, but stand on sound conviction. The networks are once again arguing and play devils' advocate over the petty follies of party loyalty and speculation instead of holding canditates accountable through substantive debate that is backed up by creditable research. Do you hate the bickering nature of politics before you that encourages disrepectfu belittlement with name calling and deceitful half truths to get ahead? I don't! It's time to put away childish things!

POPSBig Pharma in the News Money talks. And money corrupts. The story behind this story of one psychiatrist is that of the buying and selling of the nation's health. For profit healthcare is a no win situation for the consumer. Depending on an "open market" when the financial stakes are so high leads to corruption and scandal. And the consumer is sure to lose in the end.

POPS'Old-boy's club holding back innovation We all now have access to a vast amount of research and data on the net. a Few people would have absolutely no hope, but the networks being created on the web, are places where anyone can comment, or include findings, so the pieces can start coming together more quickly. It isn't what we know that is important. it's what we do with the knowledge

Some 10 percent of the population consistently works night shifts, according to the report, and 25 percent work such shifts occasionally.

The sperm in the sugar, no doubt with the chemicals in cola acting as a catalyst, cause them to 'Eat themselves to death, through osmosis, and the recognition of sugar opening some cellular gates.

POPSThe Power of a Handshake: How Touch Sustains Personal and Business Relationships Recent research from Zak's neuroeconomics lab has shown that the human brain uses oxytocin to unconsciously assess if a person is trustworthy using our memory of past encounters and all of our senses, including touch. If the stranger is a good match for other trustworthy people, the brain releases oxytocin, telling us it is safe to trust. Interesting read.

POPSLearning From Mistakes Only Works After Age 12, Study Suggests Is that difference between eight- and twelve-year-olds the result of experience, or does it have to do with the way the brain develops? As yet, nobody has the answer. 'This kind of brain research has only been possible for the last ten years or so,' says Crone, 'and there are a lot more questions which have to be answered. But it is probably a combination of the brain maturing and experience.'

POPSThe New Science of Fear: Can It Predict Bravery at 13,500 Feet?
"Mujica-Parodi says:"You're kind of like a rubber band, in that when you go up, you come back down right away. You're conserving your sympathetic dominance for when it's actually needed." These results, Mujica-Parodi says, mirror those of my fMRI session. It's not that I stayed cool when I was plummeting toward earth—"You were in actual danger," she says, so "a strong excitatory response was appropriate"—but that when I wasn't falling I suppressed the fear response and conserved my energy. The upshot: I might do well at keeping calm in the face of lethal danger, as most firemen and policemen do. More important, my results seem to reinforce Mujica-Parodi's theory, which could mean that in the future recruiters for the military and law enforcement will have a way to screen applicants for the most suitable training and job assignments. Our conversation turns back to the sky dive. "Would you go again?" Mujica-Parodi asks. "I think so," I tell her. But not right now. Maybe in a fe

POPS 'Pre-crime' detector shows promise That sounds incredibly high at such an early stage in the research - but only tests on vast quantities of real people, rather than eager volunteers, will present any real test. Questions remain, however, as to how secure the system is. The machines could reveal health conditions like heart murmurs and breathing problems as well as stress levels - which would be an invasion of privacy.
