Researchers at the Johns Hopkins Malaria Research Institute have demonstrated that the Anopheles mosquito's innate immune system could be genetically engineered to block the transmission of malaria-causing parasites to humans. In addition, they showed that the genetic modification had limited impact on the mosquito's fitness under laboratory conditions. The researchers' findings are published December 22nd in the Open Access journal PLoS Pathogens. In this study, Dimopoulos and his team...

Estimates of malaria incidence derived from routine surveillance data suggest that 225 million episodes of malaria occurred worldwide in 2009. This estimate is lower than other published figures, such as those from the Malaria Atlas Project (MAP), particularly for estimates of malaria incidence outside Africa. Richard Cibulskis and colleagues at the WHO in Geneva, Switzerland present a critique of different estimation methods of the worldwide incidence of malaria in this week's PLoS Medicine....

An antimalarial agent developed by researchers at Albert Einstein College of Medicine of Yeshiva University proved effective at clearing infections caused by the malaria parasite most lethal to humans — by literally starving the parasites to death. The novel research, carried out on a small number of non-human primates, could bolster efforts to develop more potent therapies against one of the world's leading killers. The study, published in the November 11, 2011 issue of PLoS ONE, was...

Study identifies new ways to kill the human malaria parasite, Plasmodium falciparum An international team of scientists has announced a breakthrough in the fight against malaria, paving the way for the development of new drugs to treat the deadly disease. According to the World Health Organisation malaria currently infects more than 225 million people worldwide and accounts for nearly 800,000 deaths per year. Most deaths occur among children living in Africa where a child dies every 45...

New class of compounds would target earliest stages of infection Researchers have discovered a group of chemical compounds that might one day be developed into drugs that can treat malaria infection in both the liver and the bloodstream. The study, which appears in the Nov. 18 issue of Science, was led by Elizabeth A. Winzeler, Ph.D., of the Scripps Research Institute in La Jolla, Calif., and was partially funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
