How long does it take a fruit fly to emerge from a cold-induced coma? How resistant is a fruit fly to starvation? How quickly can a fruit fly settle down after it is startled? The answer to these complex traits rests with genes, many of them that interact in complicated ways to produce an end result that is a phenotype or outward sign, said an international group of scientists, led by those from North Carolina State University, the Baylor College of Medicine Human Genome Sequencing Center...

Aphids could be considered the "mosquitoes" of the plant world, depending on the "blood" of plants to survive. They live in symbiosis with bacteria that pass from one generation to the next, producing essential amino acids. Aphids with the same genotype can be wingless or winged. In different seasons, they develop as asexual females who produce offspring with identical genes through parthenogenesis. When temperatures drop, they can give birth to males who then fertilize the eggs laid by...

Parasitic wasps kill pest insects, but their existence is largely unknown to the public. Now, scientists led by John H. Werren, professor of biology at the University of Rochester, and Stephen Richards at the Genome Sequencing Center at the Baylor College of Medicine have sequenced the genomes of three parasitoid wasp species, revealing many features that could be useful to pest control and medicine, and to enhance our understanding of genetics and evolution. The study appears in the Jan. 15...


Word of the Day
abrosia
  • Wasting away as a result of abstinence from food.
The word 'abrosia' comes from a Greek roots meaning 'not' and 'eating'.
