It's no secret how Africa can feed itself - grow more food.

That sort of naïve statement is fine for environmentalists who were born as part of the  Agricultural 1%, but it falls apart in the real world that exists outside fundraising campaigns. A large chunk of Africa doesn't grow food all that well, which historically has meant relying on the patronage of rich countries and cycles of famine - but that also has made it a political football.
It seems that CERN and the American Physical Society APS have struck a deal to make every article published by CERN in certain APS journals  open access. 

The announcement I saw read this. 
Play the video below to see how to solve the puzzle I posted last week:

The object actually appears as it is pictured. It is not an optical illusion. The image was not created using an “in camera” special effect (no special lighting, no filters other than the built-in infrared filter, no mirrors, or any other “in camera” special effect technique). The image has not been modified with digital photography editing software. The object was not taped, or glued, or otherwise fastened together. The object was created using a single piece of ordinary twenty pound bond computer printer paper and a pair of scissors. Are you able to solve the puzzle of how it was made?

I'm not a big fan of conspiracy theories.  Yes, sometimes there are conspiracies, but the Internet seems to magnify discordant cynicism on an unbelievable scale.  I begin with this disclaimer because the conspiracy theorists have come out to explain why Google would do something completely absurd.  I don't have an explanation for it, other than that I think they are reacting to the Edward Snowden scandal (which has supposedly hurt their business prospects outside the US).

The Department of Psychiatry at the University of Wisconsin School of Medicine and Public Health, Madison, WI, recently published a review discussing drug abuse in athletes. Drug abuse occurs in almost all sports and at most levels of teen and adult competition.

As most culturally astute people of a certain age know, 2015 is "The Future" of "Back To The Future II." "Back To The Future" was, of course, a seminal comedy in 1985 - a time when terrorists were from the Mid-East and you could do a time-travel experiment on your dog without getting protests outside the theater.
Students at the City Colleges of Chicago may have to do without textbooks until as late as mid October.  While the students are as bright as any they need their books, for reference, and a sense of security.  They need reassurance that what they are about to write on their homework is right.   My lectures, OneNote notes, PowerPoints, and websites can only make up for so much.  This is the case across many courses, at all campuses, in our for college credit curriculum. Not just my courses but many others as well.

Agriculture has one hell of a footprint, occupying 37.6 percent of earth’s land area, or about 0.7 hectares (1.7 acres) per person to feed our world's
