"Given the desire for ambitious scientists
to break from the pack with a striking new finding, Dr. Ioannidis reasoned, many hypotheses already start with a high chance of being wrong. Otherwise proving them right would not be so difficult and surprising — and supportive of a scientist’s career. Taking into account the human tendency to see what we want to see, unconscious bias is inevitable. Without any ill intent, a scientist may be nudged toward interpreting the data so it supports the hypothesis, even if just barely." [more inside]

We analysed 5,483,841 research papers and review articles with 27,329,915 authorships.
We find that in the most productive countries, all articles with women in dominant author positions receive fewer citations than those with men in the same positions. And this citation disadvantage is accentuated by the fact that women's publication portfolios are more domestic than their male colleagues — they profit less from the extra citations that international collaborations accrue. Given that citations now play a central part in the evaluation of researchers, this situation can only worsen gender disparities.
The data are also used to make a really cool interactive map

The emergence of a citation cartel.
"Cell Transplantation is a medical journal published by the Cognizant Communication Corporation of Putnam Valley, New York. In recent years, its impact factor has been growing rapidly. In 2006, it was 3.482. In 2010, it had almost doubled to 6.204.
When you look at which journals cite Cell Transplantation, two journals stand out noticeably: the Medical Science Monitor, and The Scientific World Journal. According to the JCR, neither of these journals cited Cell Transplantation until 2010.
Then, in 2010, a review article was published in the Medical Science Monitor citing 490 articles, 445 of which were to papers published in Cell Transplantation. All 445 citations pointed to papers published in 2008 or 2009 — the citation window from which the journal’s 2010 impact factor was derived. Of the remaining 45 citations, 44 cited the Medical Science Monitor, again, to papers published in 2008 and 2009.
Three of the four authors of this paper sit on the editorial board of Cell Transplantation. Two are associate editors, one is the founding editor. The fourth is the CEO of a medical communications company."

prospects in the field
are incredibly high
, recent trends, such as "tools grow[ing] more advanced"
(see Adobe Flash Builder
or MS Visual Studio
) have had people wondering over the past few years if computer science has much room for growth left. Some question whether it is alive.
Others, such as Carnegie Mellon
, say not so fast. In any case, employment has been a bit iffy
). There is the possibility that Computer Science is simply growing up (PDF)
, then again the U of Florida decided to say good bye to it this past week.
But hey, if you are not going to that University, and still are shooting for computer science, here are some tips

Sabotage in the lab.
"As the problems mounted, Ames was getting agitated. She was certain that someone was monkeying with her experiments, but she had no proof and no suspect. Her close friends suggested that she was being paranoid." Scientific research collides with human nature.

The Real Science Gap:
“There is no scientist shortage,” declares Harvard economics professor Richard Freeman, a pre-eminent authority on the scientific work force. Michael Teitelbaum of the Alfred P. Sloan Foundation, a leading demographer who is also a national authority on science training, cites the “profound irony” of crying shortage — as have many business leaders, including Microsoft founder Bill Gates — while scores of thousands of young Ph.D.s labor in the nation’s university labs as low-paid, temporary workers, ostensibly training for permanent faculty positions that will never exist.

Hypothesis as thought-crime
...Now, however, a new brouhaha has erupted [at Harvard]and it seems impossible that Summers [the president]will emerge from this one without serious erosion of his moral authority. The trigger was a statement he made at a conference, suggesting that the reason there are more men than women in the mathematical sciences at top-flight institutions has to do with a small statistical difference in inate ability, which becomes a pretty large disparity when one looks at the 'high end' of the respective distribution curves...
The fatal words did not set forth his main theme, but merely constituted a brief aside, thoroughly hedged and qualified. Nonetheless, they touched off a firestorm of indignation, the most striking aspect of which was the intemperate response of a number of feminist scientists, who offered no counter-arguments, but simply declared the whole idea misogynistic and therefore forbidden intellectual territory.
