Arthur T Knackerbracket has found the following story:

Caffeine consumption has been associated with lower risks for multiple diseases, including type II diabetes, heart disease, and stroke, but the mechanism underlying these protective effects has been unclear. A new study now shows that caffeine promotes the movement of a regulatory protein into mitochondria, enhancing their function and protecting cardiovascular cells from damage. The work, publishing 21 June in the open access journal PLOS Biology [...] found that the protective effect was reached at a concentration equivalent to consumption of four cups of coffee, suggesting the effect may be physiologically relevant.

The authors have previously shown that at physiologically relevant concentrations (i.e. levels reached after four or more cups of coffee) caffeine improved the functional capacity of endothelial cells, which line the interior of blood vessels, and that the effect involved mitochondria, the cell's energy powerhouses.

Here, they showed that a protein called p27, known mainly as an inhibitor of the cell cycle, was present in mitochondria in the major cell types of the heart. In these cells, mitochondrial p27 promoted migration of endothelial cells, protected heart muscle cells from cell death, and triggered the conversion of fibroblasts into cells containing contractile fibers -- all crucial for repair of heart muscle after myocardial infarction. They found that caffeine induced the movement of p27 into mitochondria, setting off this beneficial chain of events, and did so at a concentration that is reached in humans by drinking four cups of coffee. Caffeine was protective against heart damage in pre-diabetic, obese mice, and in aged mice.

    Are we SoylentNews or InfoWars now? Not that im against us having our own series of pills to protect us against free radicals and breakdown of mitochondria - but it sounds like a lot of work.

        When i am waiting for Coast to Coast to come on i sometimes catch a couple minutes of InfoWars commercials.

        Caffeine consumption has been associated with lower risks for multiple diseases, including type II diabetes, heart disease, and stroke, but the mechanism underlying these protective effects has been unclear. A new study now shows that caffeine promotes the movement of a regulatory protein into mitochondria, enhancing their function and protecting cardiovascular cells from damage.

        Sounds a lot like a commercial that you might hear followed by him hawking his pill which is an all natural blend of various caffeine substances picked at the right time of the year to help with heart health. Has caffeine from several sources because they activate differently in the body.

        I take this myself and i know it helped me feel 50 years younger.

          Alright, well, that's an association most people are not going to have with news about caffeine.

          Me, I was encouraged by the headline because I drink about a pot of coffee a day. Always nice to find out your vices are actually virtues.

              Yeah, non-ironic consumption of Infowars or its ilk borders on the pathological. For entertainment purposes, as in, "Look at all the gibbering lunatics foaming at the mouth," it has its place. Keeping an eye on the same also has value for defense, because when things blow up it starts at places like those, not among the crowd that watches the Today Show.

              O tempora, o mores, right?

        I never understood this trend. When I get my grubby hands on fresh avocados, I peel and pit them and place them in their form directly on the place before seasoning them with salt and pepper or Tabasco sauce.

        Oh yeah and coffee rocks. During a typical workday I will bomb almost exactly 4 cups of coffee, and much more if I have to pull an all-nighter. Coffee is as divine as garlic, rarely in nature do you find things which are as useful and versatile as coffee and garlic.

        One late-night study session I was already beaned-up, but decided I needed more coffee so I ordered an iced Vietnamese because I wanted something sweet. What I didn't know was that the place in question made their iced Vietnameses with 4 shots of espresso. After drinking it I was convinced that the government was out to get me, and any police siren in the background meant that they would be rappelling from the helicopters any second to take me away. For the next painful hour, I knew what it was like to be on a PCP binge.

        Coffee and cigarettes are great. But if you OD on them, there is nothing more terrifying than a coffee OD, and there is nothing more sickening and painful than a tobacco OD.
