Sigma receptors play role in cocaine-induced suppression of immune system
Cocaine use is known to have negative effects on the immune system but how the drug exerts this effect is poorly understood.

Season of birth and ethnicity may be important factors in birth weight and infant growth
The season in which a baby is born may influence the baby's birth weight as well as how quickly the baby gains weight during the first four months of life.

Real-time monitoring of brain activity helps explain how cues contribute to drug relapse
Real-time monitoring of dopamine activity in the brain shows that in rats the mere anticipation of receiving cocaine may cause significant increases in dopamine levels.

Starting marijuana use during teens may result in cognitive impairment later in life
There is evidence that individuals who start to smoke marijuana at an early age--while the brain is still developing--show greater cognitive deficits than do individuals who begin use of the drug when they are older, but the reasons for this difference are unclear.
