Watch your language!

By | October 5, 2001

Several studies have suggested that there may be a genetic component to developmental disorders of speech and language, but no specific genes have been identified. In the October 4 Nature, Cecilia Lai and colleagues at the University of Oxford report mutations in a gene that correlates with such language disorders (Nature 2001, 413:519-522).Study of a family (called KE) with speech-language disorder led to the mapping of the SPCH1 locus on chromosome 7. Lai et al. performed fluorescence in-situ

Cannabinoid protects injured brain

By | October 4, 2001

No effective drug currently exists to treat brain injury and the mechanisms that control post-trauma events remain largely unknown. In October 4 Nature, David Panikashvili and colleagues from the Hebrew University, Jerusalem, show that the cannabinoid, 2-arachidonoyl glycerol (2-AG) is part of an endogenous system that protects the brain in the period following traumatic injury.Panikashvili et al. observed that after closed head injury in mice the level of endogenous 2-AG was significantly eleva

Plague genome

By | October 4, 2001

Yersinia pestis is a Gram-positive bacterium that has wreaked havoc for centuries by causing plague pandemics such as the Black Death. Threats that Y. pestis could be used as a biological warfare agent suggest that it will continue to provide a healthcare challenge in the future. In the October 4 Nature, Parkhill et al. from The Sanger Centre report the complete genome sequence of the Y. pestis strain CO92 (Nature 2001, 413:523-527).The killer genome consists of a 4.65 megabase chromosome and th
