UCLA researchers have�discovered that�the activity of a brain region known to be involved in learning, memory and Alzheimer’s disease behaves as if it’s remembering something during sleep, even under anesthesia — a finding that counters conventional theories about memory consolidation during sleep.

His team found that the entorhinal cortex showed what is called persistent activity, which is thought to mediate working memory during waking life — for example, when people pay close attention to remember things temporarily, such as recalling a phone number or following directions.

“The big surprise here is that this kind of persistent activity is happening during sleep, pretty much all the time.” Mehta said. “These results are entirely novel and surprising. In fact, this working memory-like persistent activity occurred in the entorhinal cortex even under anesthesia.”

The findings are important, Mehta said, because humans spend one-third of their lives sleeping and a lack of sleep results in adverse effects on health, including learning and memory problems.

As leaders ascend to more powerful positions in their groups, they face ever-increasing demands. This has given rise to the common perception that leaders have higher stress levels than non-leaders. But if leaders also experience a heightened sense of control—a psychological factor known to have powerful stress-buffering effects—leadership should be associated with reduced stress levels. Using unique samples of real leaders, including military officers and government officials, we found that, compared to non-leaders, leaders had lower levels of the stress hormone cortisol and lower reports of anxiety (Study 1). In a second study, leaders holding more powerful positions exhibited lower cortisol levels and less anxiety than leaders holding less powerful positions, a relationship explained significantly by their greater sense of control. Altogether, these findings reveal a clear relationship between leadership and stress, with leadership level being inversely related to stress.

Think your moral choices are clear, concise and firm? Read this and think again.

Choice Blindness is a phenomena occurring in the areas of taste, smell and aesthetic appeal. Now, moral choice has been shown to be just as malleable. So, what is choice blindness? and why does it matter?

A simple test was conducted by researchers at Lund University. They asked random people walking through a park if they would fill out a simple questionaire about their moral principles. The questions covered topics ranging from prosititution to the Israeli-Palestinian conflict.

Surveys were filled out by 160 people, but unknown to the participants, there was a trick to them (see video): While the second page of the survey was being completed, the statements on the first page of the survey were surreptitiously changed to the opposite moral position, while leaving the participants answers the same.

Then, the participants were asked to read three of the moral positions on page 1, including two which had been altered, and discuss their response to them. The results were surprising.

HALF of the participants did not detect the changes at all. 69% accepted at least one of the altered statements. An unimaginable 53% argued unequivocally for the reversed moral position.

This is “choice blindness”. It demonstrates how malleable and flexible people really are.

A psychologist adds, “These findings suggest that if I’m fooled into thinking that I endorse a view, I’ll do the work myself to come up with my own reasons [for endorsing it],” .

The recent Science Debate poll identified “Should the United States fund a “War on Aging?” as the #1 question the scientific community wants to ask presidential candidates, gathering 3 times as many votes as any other. Yet, it was not included among the “top questions” to “tackle” that the candidates were asked.

I support a full-on war on aging, as well as the Longevity Party,  but must wonder if this question is continually swept to the nether regions because the powers-that-be don’t believe the masses will find it that useful. In reality, it isn’t likely extreme longevity technology or the enhancements therein will be readily available and/or affordable to the masses — it will be another “have” vs. “have-not” issue, only this time it will involve life vs. death on a very real basis.

Another obvious reason is the religious fanatics believe their respective deities are the givers and takers of life, despite the fact they utilize every life extension tool available to them currently (diabetes treatment, bypass surgery, medications, etc.). Any religious person  with an iota of legitimacy to their belief  would be as opposed to extreme life extension as they are to other life-engendering research.

Both of these objections need to be effectively overcome, or at least rationalized in an open and available forum, to move the Longevity Party into the sphere of a party digestable by the masses, I think.

Water, Water, Everywhere

This wind turbine literally pulls 1,000 gallons of drinkable water out of the air.

“Each unit can create 1,000 liters of drinking water using only moisture and powered only by wind. Let me highlight this word : CREATE. All existing solutions (wells, desalination, lakes/rivers pumping, etc.) only treat an existing source of water. Thus, what happens when there is no or no more water available? The WMS1000 can create water when there is no existing source available. That makes a difference. Our technology integrates water creation, water collection, water treatment and water local distribution.  The WMS1000 can produce and distribute water everywhere.”

Ideally, your immune system should operate like an enlightened action hero, meting out inflammation precisely, accurately and with deadly force when necessary, but then quickly returning to a Zen-like calm. Doing so requires an optimal balance of pro- and anti-inflammatory muscle.

In autistic individuals, the immune system fails at this balancing act. Inflammatory signals dominate. Anti-inflammatory ones are inadequate. A state of chronic activation prevails. And the more skewed toward inflammation, the more acute the autistic symptoms.
