Genome-based diets maximise growth, fecundity, and lifespan

A moderate reduction in food intake, known as dietary restriction, protects against multiple ageing-related diseases and extends life span, but can also suppress growth and fertility. A research group from the Max Planck Institute for Biology of Ageing in Cologne has now developed a diet based on the model organism’s genome, which enhances growth and […]

Secuencias Aleatorias y Funcionales

Una fracción inesperadamente elevada de secuencias de nucleótidos y aminoácidos combinados aleatoriamente resultan biológicamente activos y puede influir en la aptitud de E.coli. Esto da credibilidad a la posibilidad de que la evolución de novo de genes ha desempeñado un papel significativo en la historia evolutiva. El hallazgo también plantea preguntas nuevas, incluyendo si cualquiera de estas moléculas […]

Gorilla Genome

The gorilla genome reveals that genetic similarities among humans and the apes are more complex than expected, and allows a fresh assessment of the evolutionary mechanisms that led to the primate species seen today … Nature 483, 164–165  In 30% of the genome, gorilla is closer to human or chimpanzee than the latter are to each other; this […]
