The health benefits of coffee

This Is Your Brain on Coffee:

Other recent studies have linked moderate coffee drinking — the equivalent of three or four 5-ounce cups of coffee a day or a single venti-size Starbucks — with more specific advantages: a reduction in the risk of developing Type 2 diabetes, basal cell carcinoma (the most common skin cancer), prostate cancer, oral cancer and breast cancer recurrence.

Perhaps most consequential, animal experiments show that caffeine may reshape the biochemical environment inside our brains in ways that could stave off dementia. In a 2012 experiment at the University of Illinois at Urbana-Champaign, mice were briefly starved of oxygen, causing them to lose the ability to form memories. Half of the mice received a dose of caffeine that was the equivalent of several cups of coffee. After they were reoxygenated, the caffeinated mice regained their ability to form new memories 33 percent faster than the uncaffeinated. Close examination of the animals’ brain tissue showed that the caffeine disrupted the action of adenosine, a substance inside cells that usually provides energy, but can become destructive if it leaks out when the cells are injured or under stress. The escaped adenosine can jump-start a biochemical cascade leading to inflammation, which can disrupt the function of neurons, and potentially contribute to neurodegeneration or, in other words, dementia.

Does this mean Starbucks will start running ads touting their health benefits? They’d be like Subway’s ads, but instead of featuring people who lost weight they could show older people whose dementia “could be worse.”

The healing effects of taking in nature

How Nature Resets Our Minds and Bodies – Adam Alter – The Atlantic:

Nature restores mental functioning in the same way that food and water restore bodies. The business of everyday life — dodging traffic, making decisions and judgment calls, interacting with strangers — is depleting, and what man-made environments take away from us, nature gives back. There’s something mystical and, you might say, unscientific about this claim, but its heart actually rests in what psychologists call attention restoration theory, or ART.

This is why I love Berkeley’s campus. Everywhere you go there are trees and fields of grass and animals going about their business. I think I’m going to do more of my reading outside from now on.

Another Republican says something stupid about rape

stephen colbert gop rape

 

From Slate:

“And I’ve delivered lots of babies, and I know about these things. It is true. We tell infertile couples all the time that are having trouble conceiving because of the woman not ovulating, ‘Just relax. Drink a glass of wine. And don’t be so tense and uptight because all that adrenaline can cause you not to ovulate.’ So he was partially right wasn’t he? But the fact that a woman may have already ovulated 12 hours before she is raped, you’re not going to prevent a pregnancy there by a woman’s body shutting anything down because the horse has already left the barn, so to speak. And yet the media took that and tore it apart.”

Pregnant from a rape? You were probably too relaxed during the incident.
