Is Consciousness Fractal?

What I found fascinating is how fractal nature is and how we perceive and react to it.

Stress, evolution and cancer

Interesting theory — stress speeds up evolution.  Full article: Does Stress Speed Up Evolution?

Implication for cancer is in the last few paragraphs; here is the excerpt:

…Austin says his experiments suggest that putting too much stress on cancer cells by hitting them with high doses of cancer drugs could accelerate their evolution to develop drug resistance. “We give the patients as much as they can tolerate, guaranteeing the emergence of resistant cancer cells,” he says, adding that the current aggressive approach to cancer treatment has largely failed.

Instead, he is culturing cancer cells on his death galaxy to find the right low-dosing and timing of cancer drugs that keep the cancer cells from spreading without killing them—hopefully delaying the evolution of resistance as long as possible.

At least in an ovarian cancer model in mice, the approach seems to work. In 2009, Robert Gatenby, a radiologist at the Moffitt Cancer Center in Tampa, Florida, and his colleagues reported that interrupting, or down-adjusting, therapy as long as the tumor volume didn’t increase prolonged survival in these mice compared with the standard aggressive regimen. “If you give them standard high-dose therapy, the tumor can almost completely go away and then come back very rapidly and be resistant,” Gatenby says. “If you use an adaptive approach, we can consistently get control of the tumor.” Gatenby is now testing the approach in a 40-patient open clinical trial in patients with late-stage prostate cancer….

What I Learned from Losing $200 Million

In summary: illusion of control. And that stress amplifies it.

Stress in contagious

If you won’t take the trouble to learn how to handle stress for yourself, at least do so for your loved ones:

…“People may think they can hide their stress from loved ones or co-workers, but in many cases, they do not, and so others around them may be affected without knowing.”…

Evidence is starting to come in that our gut bacteria not only affect our health, but also our behaviour.

Fruits and Vegetables Are Trying to Kill You

Vitamins don’t replace fruits and veggies. Organic fruits maybe more “nutritious” after all. And a bit of stress may be good for us.

Fruits and Vegetables Are Trying to Kill You

Antioxidant vitamins don’t stress us like plants do—and don’t have their beneficial effect.

Misery Index

Low social status seems to activate genes associated with inflammation and the production of various immune-related cells and chemical signalling factors — sounds like low-level chronic stress to me.  It affects the responsiveness of the body to the glucocorticoids (stress) hormones.  Just from a blood test, scientists were able to predict the social status within 80% accuracy. Especially noteworthy is the discovery that all this stems from epigenetics.  From the print edition of The Economist, Apr 14th 2012:

Social status and health:Misery index

Low social status is bad for your health. Biologists are starting to understand why
