Nature is affectionately known amongst the research community (mostly those who have not had a Nature paper) as the Journal of Irreproducible Results. Nature has been responsible for some publishing disasters - cold fusion comes to mind but the other journals should not gloat.
Here are a couple of articles about why science is often wrong

Data Scraping and Privacy
It is amazing to see how far "reputable" companies will go at the request of others to pry into people's personal affairs.
This is what I have come to expect from Big Pharma, but not of the scrapers.

Video Game Violence
How are you to objectively measure the effect of video games on level of violence?
Here are some articles about a study that tries to create an objective measure.
Techdirt: does-being-more-vocal-video-game-violence-debate-mean-you-have-better-argument.shtml
eurekalert: Press Release
So the way the "study" creates this objective measure is by weighing the number of publications produced by both sides of an argument. I wonder if they have ever heard of the field called publication bias.
Here is another study that finds a link between video games and mental health issues

What are the chances?
Here are another pair of news stories from the 27th of February 2011. Both made the front page of the BBC website that day and both were about fatalities of people who had come from Tadcaster Yorkshire

So coincidences happen ridiculously often, you always need to think about the data.

Getting the most out of Google - part 1
Basic Searching
- Phrases in quotation marks.
- Default Boolean is AND.
- Use OR explicitly.
- Negate using the minus sign (should not contain). Minus must not be separated by a space.
- Use a + to make an explicit inclusion of a short word ignored by Google e.g. +the.
- Also search with synonyms by using the ~ character.
- Number ranges are separated by .. e.g. 5..10. If the second number is missing it will be a maximum or minimum.
- There are no stemming wildcards - so * only is a wildcard for a complete word.
Special Syntax
These allow you to focus your search onto certain elements of the web.intitle:
limits the search to the titles of webpages.inanchor:
searches only in hyperlinksintext:
searches only in the page text - not anchors, URLs.insite:
restrict the search to a particular domain.inurl:
limits the search to a particular page.link:
searches for pages that link to that URL.cache:
searches the cache - this is useful if the page has moved/been deleted.filetype:
searches for suffixes of that filetype e.g. ppt.related:
finds related pages.define:
finds related definitions.
