I have failed in finding parasites in mosquitoes fed on malaria patients, but perhaps I am not using the proper kind of mosquito.
Inevitably, malaria parasites developed resistance to commonly used drugs, and mosquito vectors became insecticide-resistant.
The Aedes aegypti mosquito, which spreads dengue fever and yellow fever, has traditionally been unable to survive at altitudes higher than 1,000 meters because of colder temperatures there. But with recent warming trends, those mosquitoes have now been reported at 1,240 meters in Costa Rica and at 2,200 meters in Columbia. Malaria-bearing mosquitoes, too, have moved to higher elevations in central Africa, Asia, and parts of Latin America, triggering new outbreaks of the disease.
The parasite that causes malaria edges through the cells of the stomach wall of the mosquito and forms a cyst which grows and eventually bursts to release hundreds of sporozoites into the body cavity of the mosquito ... As far as we can tell, the parasite does not harm the mosquito ... It has always seemed to me, though, that these growing cysts ... must at least give the mosquito something corresponding to a stomach-ache.
Many diseases including malaria, dengue, meningitis - just a few examples - these are what we call climate-sensitive diseases, because such climate dimensions for rainfall, humidity and temperature would influence the epidemics, the outbreaks, either directly influencing the parasites or the mosquitoes that carry them.
The tool that's most associated with the recent progress against malaria is the long-lasting bed net. Bed nets are a fantastic innovation. But we can do even better. We can invent new ways to control the mosquitoes that carry the malaria parasite.
I worked for a company called Population Services International, a social marketing company advocating healthy behaviors. We had a big branding campaign with celebrities to help educate about the proper use of mosquito nets, for example, to help prevent malaria.
I had the opportunity of making necropsies on patients dead from malignant fever and of studying the melanaemia, i.e., the formation of black pigment in the blood of patients affected by malaria.
As with mosquitoes, horseflies, and most bloodsucking parasites, Kenneth Starr was spawned in stagnant water.
The very first company I started failed with a great bang. The second one failed a little bit less, but still failed. The third one, you know, proper failed, but it was kind of okay. I recovered quickly. Number four almost didn't fail. It still didn't really feel great, but it did okay. Number five was PayPal.
I don't think the Federal Reserve has any role in how high rates are right now. I don't understand why everyone is paying attention to this tapering. The Fed is using one kind of bond to buy another kind of bond. What's the big deal, and why is anyone taking the Fed seriously?
If only Africa had more mosquito nets then every year we could save millions of mosquitoes from dying needlessly of aids.
So, that was Nature's way. The mosquito felt pain and panic but the dragonfly knew nothing of cruelty. Humans would call it evil, the big dragonfly destroying the mosquito and ignoring the little insects suffering. Yet humans hated mosquitoes too, calling them vicious and bloodthirsty. All these words, words like 'evil' and 'vicious', they meant nothing to Nature. Yes, evil was a human invention.
For the first time, we have the genetic sequences of all three of the players in the global malaria debacle: the parasite, the anopheles mosquito and the human. It's a very important milestone.
... finding that in [the Moon] there is a provision of light and heat; also in appearance, a soil proper for habitation fully as good as ours, if not perhaps better who can say that it is not extremely probable, nay beyond doubt, that there must be inhabitants on the Moon of some kind or other?
The implied threat of using nuclear weapons to curb guerrillas was as absurd as to talk of using a sledge hammer to ward off a swarm of mosquitoes.
The belief is growing on me that the disease is communicated by the bite of the mosquito. ... She always injects a small quantity of fluid with her bite-what if the parasites get into the system in this manner.
