Reading the dark heart of chromosomes

Although the genomes of thousands of plant and animal species have been sequenced, for most of these genomes a significant portion is missing—the highly repetitive DNA. In the midst of these mysterious genome compartments ...

Study unlocks secrets of an elusive genome compartment

Although much of the human genome has been sequenced and assembled, scientists have hit roadblocks trying to map unassembled regions of DNA that consist mostly of repetitive sequences, including the centromere.

Amino acid in fruit fly intestines found to regulate sleep

A team of researchers affiliated with several institutions in China has found that an amino acid made in fruit fly intestines plays a key role in regulating their sleep. In their paper published in the journal Nature Communications, ...

How do insects feel the heat?

Every year, nearly 700 million people contract mosquito-borne illnesses such as malaria, dengue, West Nile virus or yellow fever.

Mothers use sex pheromones to veil eggs, preventing cannibalism

Species that lay eggs but don't actively keep watch over them often protect their precious eggs from predators by laying them in communal groups or by fortifying them with toxins. However, protecting these eggs from being ...

Flies release neuronal brakes to fly longer

While mechanical and biophysical aspects of insect flight are well studied, the neurobiology and circuitry underlying it remain poorly understood. For insects, while muscles provide the power for flying, the brain coordinates ...

Fruit flies help to shed light on the evolution of metabolism

Diet choice of animal species is highly variable. Some species are specialists feeding only on one food source, such as a sugar-rich fruit or protein-rich meat. Other species, like humans, are generalists that can feed on ...

Drosophila

Drosophila is a genus of small flies, belonging to the family Drosophilidae, whose members are often called "fruit flies" or more appropriately (though less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly. One species of Drosophila in particular, D. melanogaster, has been heavily used in research in genetics and is a common model organism in developmental biology. Indeed, the terms "fruit fly" and "Drosophila" are often used synonymously with D. melanogaster in modern biological literature. The entire genus, however, contains more than 1,500 species and is very diverse in appearance, behavior, and breeding habitat.
