Scripps research scientists solve structure of a critical innate immune system protein

... name that comes from their resemblance to a fruit fly receptor called "Toll." In the fly, Toll is important for both embryonic development and for immune functions of the adult organism. In adult fruit flies, the protein is an essential receptor molecule that defends against fungal infections. In human...

Mosaic mouse technique offers a powerful new tool to study diseases and genetics

A powerful laboratory technique used by fruit fly geneticists for more than a decade is now available to scientists studying genes and diseases in mice. Writing in the May 6 edition of the journal Cell, researchers from Stanford University describe a streamlined method for creating a "genetic mosai...

MicroRNAs play a big part in gene regulation - and evolution

...s have multiple target genes and that even a fruit fly (Drosophila) has up to 14,000 genes that microRNAs could influence.

Researchers discover key gene involved in bark beetle pheromone production

...e they are protected. Only for a few hours do they fly from one tree to another to join other bark beetles, mate and start a new life cycle. But other bark beetles know where to locate mates because they are responding to an "aggregation" pheromone. If this pheromone could be disrupted, the beetles woul...

Life detection instrument passes key test on road to Mars

The MOA will be integrated with the Mars Organic Detector, which is being assembled by scientists directed by Frank Grunthaner at the Jet Propulsion Laboratory (JPL)...

Researchers Identify Cause of Early Bird Sleep Disorder

Such studies may help unravel some of the fundamental mysteries of how circadian rhythms are esta...

Fungus Effective Against Winged Termites

...ging in late April through June, the winged adults fly briefly before they drop to the ground, shed their wings and find a mate with which to start a new colony that may grow to hundreds of thousands of wood-destroying termites. The researchers' find is significant, according to Raina, because many curr...
