A potential biological cause for sudden infant death syndrome
...cells that make and use serotonin, one of over 100 chemicals
in the brain that transmit messages from one nerve cell to another. Based on their findings, Kinney, Paterson and colleagues hope to develop a diagnostic test to identify infants at risk for SIDS. They also envision a drug or other type of treatme...

Different strategies underlie the ecology of microbial invasions
...sms of killing competitors: through the release of chemicals
(for example, antibiotics or bacteriocins) and through the release of parasites (for example, bacterial viruses, known as phages). Focusing on the second mechanism in an experimental setting, the researchers showed that even though some of the invadi...
