The Red Lady burial site in El Mirón cave, outside Ramales de la Victoria in Cantabria, Spain, dates back to the Upper Palaeolithic 16,000 years ago. The archaeological site was discovered in 1903 but it wasn't until 2010 that bones were discovered at the back of the cave, in a small space between the wall and a fallen block. Both the bones and the sediment under them were reddish.

The remains turned out to be of a woman, between 35 and 40 years of age, and because of the color the Red Lady mystery was born. The reddish color means the use of ochre and ochre has been linked to religious symbolism in various cultures.

Have you been avoiding Taco Bell because of the Yellow No. 6 dye in its nacho cheese? 

Of course not. And if removing that or carmine from its red tortilla chips means you will suddenly think their food is healthy, you are being educated by advertising.

Which is just what they are hoping.

There is nothing healthy about Taco Bell or Pizza Hut or Chipotle yet they have all delivered similar intellectual placebos to the public in order to boost sales. And it's working, or at least they think it is working, since more and more junk food chains attach this health halo to their products because supposedly consumers are demanding it. Whether that turns out to be virtual money or real money is the question.

Like organic food, open access publishing has shrouded itself in a cultural halo, but it's still a business. No one is pumping out 40,000 articles per year, most of them with just a few check boxes called 'editorial review', because the 40,000 best articles happened to show up in their Inboxes, they do it to keep the lights on.

If you like mummies (and who doesn't like mummies?) you are in luck: The Anatomical Record has a special issue with 26 articles devoted to them, all open access. You may not leave the house this weekend.

A paper in Science has been retracted - by the senior author. Because he did not know the data in his paper was fake.

Whether that makes political science or the peer review system look worse will be a matter of debate.
