Genetic Influences on the Brain's Reward and Stress Systems Underlie Co-Occurring Alcohol Use Disorder and Chronic Pain

Thu, 19 Oct 2017 10:00:00 EST

Alcohol use disorder (AUD) often co-occurs with chronic pain (CP), yet the relationship between the two is complex - involving genetic, neurophysiological, and behavioral elements - and is poorly understood. This review addressed the genetic influences on brain reward and stress systems that neurological research suggests may contribute to the co-occurrence of AUD and CP.(image)

Battling Flames Increases Firefighters' Exposure to Carcinogens

Wed, 18 Oct 2017 15:05:14 EST

The threat of getting burned by roaring flames is an obvious danger of firefighting, but other health risks are more subtle. For example, firefighters have been found to develop cancer at higher rates than the general population. Now researchers have measured how much firefighters' exposure to carcinogens and other harmful compounds increases when fighting fires. Their study, appearing in ACS' Environmental Science & Technology, also points to one possible way to reduce that exposure.(image)



How a 'Star Wars' Parody Turned Into a Tool for Scientific Discovery (Video)

Wed, 18 Oct 2017 14:40:23 EST
