Studying Fruit Flies On The International Space Station
2014-07-09 03:40:57

[ Watch The Video: ScienceCasts: Fruit Flies On The International Space Station ] Dr. Tony Phillips, Science@NASA Fruit flies are bug eyed and spindly, they love rotten bananas, and, following orders from their pin-sized brains, they can lay hundreds of eggs every day. We have a lot in common. Genetically speaking, people and fruit flies are surprisingly alike, explains biologist Sharmila Bhattacharya of NASA's Ames Research Center. "About 77% of known human disease genes...

Fruit fly study shows Hypergravity may help mitigate biological problems in space
2014-07-01 03:55:42

[ Watch The Video: ScienceCasts: Fruit Flies On The International Space Station ] Laura Niles, NASA Before you swat away the next fruit fly, consider instead just how similar its biological complexities are to our own. In a study published in PLOS ONE, researchers led by Deborah Kimbrell, Ph.D., at the University of California, Davis (UC Davis) and their collaborators, studied how microorganisms may alter fruit flies’ immunity in space and in hypergravity, or increased gravity. The...

Controlling Fruit Fly Movements With A Mind-Altering Device
2014-05-26 11:15:03

Alan McStravick for redorbit.com - Your Universe Online A joint collaboration between the Vienna University of Technology and US researchers, has resulted in the development of a unique and novel technique to control Drosophila melangogaster, perhaps better known as the fruit fly, via thermogenetic means. The control the researchers exert is ultimately able to be analyzed at the neural level within the brains of the insects. Much of the work was conducted at the Information Management...

Fly model previously used to pinpoint genetic variance in toxicity of chemotherapeutic agent As Rachel Carson predicted 50 years ago in her groundbreaking book Silent Spring, crop pests are capable of outwitting the chemical compounds known as xenobiotics that are devised to kill them. This development of resistance to insecticides is a serious problem because it threatens crop production and thereby can influence the availability and costs of many foods as well as the economy. To...

Gene encodes protein that regulates formation and maintenance of muscle tissue Skeletal muscle cells with unevenly spaced nuclei, or nuclei in the wrong location, are telltale signs of such inherited muscle diseases as Emery-Dreifuss muscular dystrophy, which occurs in one out of every 100,000 births, and centronuclear myopathy, which affects one out of every 50,000 infants. What goes wrong during myogenesis, the formation and maintenance of muscle tissue, to produce these inherited...

Insect Pests In The Making
2014-03-19 21:19:27

UC Davis Of thousands of known species of Drosophila fruit flies, just one is known as a crop pest, depositing eggs inside ripening fruit so its maggots can feed and grow. New research from the University of California, Davis, shows the similarities and crucial differences between this pest and its close relatives — and that one related fly has potential to also become a pest. Drosophila flies, found worldwide, lay their eggs in rotting fruit. Drosophila suzukii, also referred to as...

Flies That Live With Their Brothers Are Gentler Lovers
2014-01-23 13:39:47

University of Oxford Flies living with their brothers cause less harm to females during courting than those living with unrelated flies, say Oxford University scientists. The study, published this week in Nature, found that unrelated male flies compete more fiercely for females' attention than related flies, resulting in shorter lifespans for males and reduced fecundity for females. "In large populations brothers don't need to compete so much with each other for female attention...

Fly Eye Wins Huygens Image Contest
2014-01-15 15:31:48

Research Institute of Molecular Pathology Karin Panser is a member of Andrew Straw’s group at the IMP Vienna. The team addresses the fundamental question of how the brain of a fruit fly functions. "We aim to understand how the fly processes complex visual input and translates that into a specific coordinated behavior," Panser explains. For her neuroscientific studies, she needs greatly enlarged, detailed pictures generated with a confocal microscope. To process and analyze her data,...

Cell Migration Study Provides Insights Into The Movement Of Cancer Cells
2013-11-21 11:24:35

IRB Barcelona Using Drosophila melanogaster, researchers at IRB Barcelona discover that during multiple cell migrations a single cell can act as leader, dragging the others with it. The migration of groups of cells in order to form tissues is common during the development of an organism. Discovering how these multiple movements are achieved is not only crucial to understand the basic principles of development but provides new information and insights for further research into processes...

Why do crosses between closely related species fail to produce fertile hybrids? A new study shows that differences in the levels - not necessarily the sequences - of certain key proteins are crucial in mediating reproductive isolation. Two individuals are defined as belonging to the same biological species, if matings between them give rise to viable and fertile offspring. Crosses between closely related, but already distinct, species produce hybrid offspring that are either inviable or...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
