The PBF Energy refinery in Paulsboro, N.J., uses toxic chemicals such as hydrofluoric acid. Rather than using "inherently safer" design methods, the industry says, other safety measures are taken to prevent accidents like the one in West, Texas.

The West Fertilizer Co., shown from the air, lies in ruins after an explosion that killed 15 people, injured more than 150 and damaged houses and buildings for blocks in every direction.
You might think that everything would have changed for the chemicals industry on April 16, 1947. That was the day of the Texas City Disaster, the worst industrial accident in U.S. history. A ship loaded with ammonium nitrate — the same chemical that appears to have caused the disaster last month in West, Texas — exploded. The ship sparked a chain reaction of blasts at chemical facilities onshore, creating what a newsreel at the time called "a holocaust that baffles description."
Despite significant advances in neurology and imaging, researchers still don't have simple lab tests for diagnosing patients with mental disorders. Diagnoses are still mostly based on a patient's signs and symptoms.

The Diagnostic and Statistical Manual of Mental Disorders, or DSM, is the official list of all the mental disorders doctors can use to diagnose mental illness. It's updated every 20 years or so.
The American Psychiatric Association is about to release an updated version of its Diagnostic and Statistical Manual of Mental Disorders. The DSM helps mental health professionals decide who has problems such as depression, anxiety and schizophrenia.
Psychiatry's new manual, DSM-5, has been nearly 20 years in the making. During that time, scientists have learned a lot about the brain. Yet despite some tweaks to categories such as autism and mood disorders, DSM-5 is remarkably similar to the version issued in 1994.
For decades, Hill County Farms, also known as Henry's Turkey Service, housed a group of mentally disabled men in squalor in this former schoolhouse in Atalissa, Iowa. The EEOC won a judgment against the company for exploiting the men.

Four years ago, 21 men with intellectual disabilities were emancipated from a bright blue, century-old schoolhouse in Atalissa, Iowa. They ranged in age from their 40s to their 60s, and for most of their adult lives they had worked for next to nothing and lived in dangerously unsanitary conditions.
Earlier this month, the Equal Employment Opportunity Commission won a massive judgment against the turkey-processing company at which the men worked. The civil suit involved severe physical and emotional abuse of men with intellectual disabilities.
