Investigations: Inside Quebec Construction's Organized Crime and Political Ties

Here's a fascinating look inside Quebec's notoriously corrupt construction industry, including its links with organized crime and political fundraisers. Radio-Canada has made public this 72-page report from Quebec's anti-corruption investigative squad, based on a year-and-a-half-long inquiry.

The report speaks of a "deeply rooted and clandestine universe of an unsuspected scope that is harmful to our society - in terms of security, the economy, justice and democracy."

Investigations: F-35 Wings to Last Just Five Years

Yet another setback for the massively expensive F-35 warplane - the most costly military program in history (full operating cost: an estimated $1 trillion). Already beset by delays, cost overruns and performance questions, two of the three models of the $100-million-plus planes have been found to have a major structural defect. The result is their wings have an operational life of only five years, according to this Wired report. That's a lot less than the expected 25 years.

Earlier reports had questioned the F-35's key attribute - its supposed stealthiness. This Wired story cites a study that found the jet is "demonstrably not a true stealth aircraft" and can't operate against Russia's latest air defence systems. An aviation expert said the F-35's stealthiness is undermined by its "very conventional-airplane-shaped lumps and bumps around its underside, not to mention the hideous wart that covers the gun on the F-35A."

Investigations: Suits to Target Rampant Medical Ghost-writing

CBC Radio explores the widespread practice of "medical ghost-writing" in this interesting report (available in audio or text form). That's when doctors and scientists put their name on papers that were actually written and researched with funds from pharmaceutical companies, whose contributions aren't acknowledged. The result: side-effects from medications can be downplayed - or omitted altogether, according to the report. Now, two lawyers are preparing to fight back with lawsuits alleging fraud.
