Aspirin and Cancer: A Seriously Cost-Effective Measure
At Freakonomics, we’re all about finding cheap, easy solutions to life’s big problems. And judging by the results of a new study published in The Lancet, a rather large one just came down the pike. Turns out that aspirin may be one of the most effective measures to combat colon cancer. The study found that taking two aspirin pills a day for two years reduced the risk of colorectal cancer by 63 percent in a group of 861 people who have Lynch syndrome, and are therefore at a high risk for the disease.
Though there have been previous studies that suggest aspirin may effectively reduce the risk of cancer (like this one from 2010), according to the BBC, this most recent study was the first randomized control trial specifically for aspirin and cancer to prove it. So, while we’ve spent what probably amounts to tens of billions of dollars in pharmaceutical R&D trying to come up with an effective cancer drug, one of the best methods may have been already sitting in our medicine cabinet, at just a few bucks a bottle.

Should Mexican Drug Cartels Be Labeled as Insurgents?
A few weeks ago, Freakonomics received an email from a man in Mexico City describing the effects of Mexican drug cartel violence on daily life and asking for our solutions to his country’s seemingly endless crime problems. This week, The New York Times ran a piece on Mexican drug cartels and growing American infiltration of criminal organizations. Now, a new report from RAND on drug-trafficking violence in Mexico analyzes the situation in the context of an insurgency, bringing to bear research on defense-sector reform.
What’s clear is that the drug-fueled violence in Mexico has diversified over the last decade into several other underworld activities: human trafficking, weapon trafficking, and assassinations, just to name a few. In other words, the cartels are no longer just cartels — they are something larger.
The RAND paper reiterates many points that have become familiar to us about the situation in Mexico: corruption is rife, policing is weak. It also looks at how high unemployment and a “youth bulge” have helped fuel Violent Drug Trafficking Organizations (VDTO). For many young unemployed people, joining a crime syndicate is often the best job option. But the most jarring part of the paper is the discussion and comparison of Mexican drug violence to other insurgency trends around the world. Rather than a war on crime, what if the battle with cartels is really a battle with different insurgent groups? Read More »
Bring Your Questions for Mara Hvistendahl, Author of Unnatural Selection
Mara Hvistendahl‘s research features prominently in our latest podcast, “Misadventures in Baby-Making.” Her book, Unnatural Selection: Choosing Boys Over Girls and the Consequences of a World Full of Men, looks at how advancements in prenatal technology have led to extreme cases of gender selection across much of Asia.
As economic development spurs people in developing countries to have fewer children and gives them access to technologies such as ultrasound, parents are making sure that at least one of their children is a boy. As a result, sex-selective abortion has left more than 160 million females “missing” from Asia’s population. It’s estimated that by 2020, 15 percent of men in China and northwest India will have no female counterpart. The consequences of that imbalance are far-reaching and include rises in sex-trafficking, bride-buying and a spike in crime as well.
Mara is currently a Beijing-based correspondent for Science. She has kindly agreed to answer your questions on her book and research. So, as always, fire away in the comments section, and we will post her replies in due course. In the meantime, here is the table of contents of Unnatural Selection. Read More »
