Decade-Long Study Unlocks Full Genetic Map Of The Deadly Tsetse Fly
2014-04-25 07:15:45

Lawrence LeBlond for redOrbit.com - Your Universe Online A nearly decade-long study involving more than 140 scientists from around the world has resulted in the successful mapping of the tsetse fly’s genetic code. Researchers involved in the study say this could open the door to scientific breakthroughs that could potentially end the scourge of sleeping sickness in sub-Saharan Africa. The tsetse fly, scientifically known as Glossina morsitans, is the sole carrier of a disease that...

Zebra Stripes Are Meant To Ward Off Biting Flies
2014-04-01 13:22:59

Brett Smith for redOrbit.com - Your Universe Online Zebras are known for their signature black-and-white stripes and a new study published in the journal Nature Communications has found more evidence that biting flies are actually the reason behind the evolution of this unique coloration. The origin of the stripes was actually debated by Alfred Russel Wallace and Charles Darwin 120 years ago. Theories surrounding their value include a form of camouflage, a distracting effect on...

Caught in the act! Researchers from the University of Bristol have observed mating for the first time in the microbes responsible for African sleeping sickness. This tropical disease is caused by trypanosomes, single-celled parasites that are found in the blood of those afflicted. The Bristol team were able to see what the trypanosomes were getting up to inside the tsetse flies that carry the disease by using fluorescent markers [see image – link below]. The microscopic beasts were seen...

Innovative Approach Could Ultimately End Sleeping Sickness Disease

Oregon State University A tag team of two bacteria, one of them genetically modified, has a good chance to reduce or even eliminate the deadly disease African trypanosomiasis, or sleeping sickness, researchers at Oregon State University conclude in a recent mathematical modeling study. African trypanosomiasis, caused by a parasite carried by the tsetse fly, infects 30,000 people in sub-Saharan Africa each year and is almost always fatal without treatment. In a 2008 epidemic, 48,000...

New Hope For Sleeping Sickness Drug
2012-11-30 12:32:48

Connie K. Ho for redOrbit.com — Your Universe Online Scientists from the Helmholtz Association of German Research Centers and the Department of Energy´s (DOE) SLAC National Accelerator Laboratory recently revealed that X-rays could provide information on a novel biological structure that could possibly be developed into a sleeping sickness drug. The findings were discovered with the help of a free-electron laser that is considered the most powerful in the world. Sleeping...

Lies Van Nieuwenhove, researcher at the Antwerp Institute of Tropical Medicine, has produced proteins imitating typical parts of the sleeping sickness parasite. They can be used in more efficient diagnostic tests, without the need for culturing dangerous parasites. Each year many thousands of Africans contract sleeping sickness. The cause is a unicellular parasite, a trypanosome, which is transmitted by the bite of tsetse flies. First the parasite multiplies in blood and lymph, while...

MSU Plan Would Control Deadly Tsetse Fly
2012-05-07 09:41:04

For the first time, scientists have created a satellite-guided plan to effectively control the tsetse fly — an African killer that spreads “sleeping sickness” disease among humans and animals and wipes out $4.5 billion in livestock every year. Michigan State University researchers developed the plan using a decade´s worth of NASA satellite images of Kenyan landscape and by monitoring tsetse movement. With unprecedented precision, the plan can tell where and when to...

Targeting the vital enzymes in female flies could aid tsetse reduction efforts An unprecedented study of intra-uterine lactation in the tsetse fly, published 18 April 2012 in Biology of Reproduction's Papers-in-Press, reveals that an enzyme found in the fly's milk functions similarly in mammals, making the tsetse a potential model for lipid metabolism during mammalian lactation. Better yet, reduced levels of this enzyme led to poor health in offspring, leading the authors to suggest...

Research led by scientists at the London School of Hygiene & Tropical Medicine has exploited a revolutionary genetic technique to discover how human African Trypanosomiasis (HAT) drugs target the parasite which causes the disease. The new knowledge could help lead to the development of better treatments for the tens of thousands of people in sub-Saharan Africa who are affected each year. The findings, published in Nature, are based on the simultaneous analysis of thousands of genes and...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
