Today in Research: Higher Cancer Rates for 9/11 Police Officers; More

Discovered: The oldest painting ever; high cancer rates for 9/11 heroes; slang does not equal stupidity; spinning is literally like having a heart attack; the gender wage gap is getting better, faster.

• High cancer rates for 9/11 police officers. Cancer rates have tripled among NYPD officers who responded at Ground Zero during the attacks of September 11. Since then, 297 cops have been diagnosed with the disease, with 56 dead. Cancer isn't the only affliction our country's bravest face: Studies have also shown higher rates of cardiovascular issues, PTSD, headaches, and "compassion fatigue." Not exactly a medal of honor.

And it turns out there's a very scientific reason for that. People who took part in a 30-minute-long spinning session produced the same biochemicals as heart attacks. It's not unhealthy, say researchers, but we think we'll stick to our apparently deadly exercise of choice just in case. [University of Gothenberg]
