One thing you probably know about black holes, no matter how much science you took, is that they have never actually been seen.   Instead, the science consensus is that masses that sit at the centers of galaxies like our own Milky Way are presumed to be black holes.

Researchers in Nature Physics say a property of light called orbital angular momentum may be detectable because of a 'twist' in this momentum caused by black holes.  And we could detect it, if we just know what to look for.

Is a lack of diversity in science writing a bad thing?   Yes and no.   Obviously if science writing relied on conservatives and the free market where people will only work for what capitalism will bear, Science 2.0 could not exist.   Academics, progressives or liberals in America (I have made the case that they are quite distinct in America, however - see Like Freedom? Thank A Scientist - How Science Made America Possible), both famous and non-famous, have contributed here for no reason other than a desire to communicate science.

While many in America were happy about the collapse of the Mubarak government, they were likely happy for the wrong reasons.   Optimists, it is said, are people who do not learn from experience and the toppling of a dictator in Egypt looks a lot more like Iran in 1979 than it does America in 1776.

But regardless of the irrational optimism of many in the political spectrum, plenty of scientists are going to be happy that protesters have now turned their sights on Zawi Hawass, a man who could only have gotten his job in a dictatorship and wielded his position just like one.
