Malaria: Scientific breakthrough to wipe off malaria


Researchers at the Johns Hopkins Bloomberg School of Public Health have for the first time identified a molecular pathway that triggers an immune response in multiple mosquito species capable of stopping the development of Plasmodium falciparum — the parasite that causes malaria in humans (report on Lindsey's caspar/cactus paper)-

Skywalker meets Anopheles


"Star Wars" Laser Kills Mosquitoes
Physicists have created a laser weapon that targets mosquitoes. It is hoped that by finding an effective weapon against mosquitoes, the incidence of malaria could be reduced. Today, malaria kills about one million people every year around the world.

AMERICAN scientists are making a ray gun to kill mosquitoes. Using technology developed under the Star Wars anti-missile programme, the zapper is being built in Seattle where astrophysicists have created a laser that locks onto airborne insects.Read the entire article:

FLYING SYRINGES

The Bill & Melinda Gates charitable foundation has awarded 104 grants, each for $100,000, in a bid to inject entrepreneurial boldness and risk-taking into the often staid world of medical research ....... The winning grants offer a bewildering array of ideas from a bewildering array of researchers. Hiroyuki Matsuoka of Jichi Medical University in Japan wants to turn mosquitoes into flying syringes to deliver vaccines rather than illness.

Mosquitoes Are The Toughest Living Beings - Or Aliens?


Russians: Mosquito Survives in Outer Space

According to the Russian news agency RIA Novosti, a mosquito managed to live 18 months clinging to the outside of the International Space Station, without any food, being bombarded by radiation and enduring fluctuating temperatures ranging from minus 230 degrees to 140 degrees Fahrenheit.
"We brought him back to Earth. He is alive, and his feet are moving," Anatoly Grigoryev of the Russian Academy of Sciences told RIA Novosti.
The buzzing bug was part of a larger experiment in which bacteria, barley seeds, small crustaceans and larval insects were placed in a container strapped to the exterior of the space station, which orbits in zero gravity about 200 miles above the surface of the Earth.
From the RIA Novosti report, it wasn't clear if the insect — which may in fact be a non-biting midge rather than a mosquito — was placed in the container in the larval or the adult stage.
A European Space Agency experiment last fall found that primitive animals called tardigrades, also known as water bears, survived an even harsher exposure to space, including full vacuum and direct solar ultraviolet blasts. Moreover, several of the surviving tardigrades were able to normally reproduce. FOX NEWS Tuesday, February 24, 2009 .


Bite and Bite Again


Q. When you wake up with several mosquito bites and find one very bloated mosquito in the room, why has it bitten you so many times in a short period?
