Scientists hard at work at eradicating malaria have often focused on the malaria-carrying mosquito, creating solutions ranging from genetic modification to malaria-attacking fungi to stinky sock lures (and about a billion more). The latest is a radiation treatment that effectively makes some male mosquitoes sterile--which, due to the particular mating habits of these mosquitoes, could have a drastic effect on mosquito populations.

"The animals are telling us things," said Martin Wikelski, hopping out of the cockpit of his Cessna. He had just spent a chilly January morning chasing blackbirds in southern France. "Maybe they're saying, 'the next earthquake will happen this week,' or 'listen, we're telling you where this ebola outbreak is headed. Pay attention.'" The blackbirds hadn't been quite so explicit today, but by tracking data from radio tags temporarily glued to their backs, he had learned their heart rates and how fast they flap their wings.

One of the toughest things about Type 1 diabetes – a chronic, incurable autoimmune disease – is that once it begins to develop, there's no way to stop it. Slowly but surely, your immune system will kill off the cells in your pancreas that produce insulin, a crucial hormone that allows you to absorb the energy (in the form of glucose) from your food. The process can take years, but the end result is always the same: you'll be entirely dependent on injections of artificial insulin to stay alive. Even though it's now possible to predict with more than 75 percent accuracy whether someone will develop Type 1 within the next five years, there's nothing to do with that information but wait.
But a new trial, launched through the National Institutes of Health's Type 1 Diabetes Trial Net, may change that.
Peeing on your phone seems like an all-around pretty bad idea, but British researchers have managed to find an upside. They claim that by urinating on a computer chip and plugging it into a phone or computer, people will soon be able to easily self-diagnose sexually transmitted diseases.

The fastest way to spread disease is to pack a lot of sick people in one place. That’s why hospitals are such a health hazard — equipment and personnel move from patient to patient and carry infectious agents in the process. One solution is to keep better track of every patient, wheelchair and IV stand to locate what’s spreading disease and what needs to be sterilized, and one Canadian company is the first to deploy a system to do just that.
Scientists at the University of Arizona have successfully bred genetically modified mosquitoes that are 100 percent resistant to the malaria parasite, rendering the mosquito incapable of infecting humans with malaria.
Researchers have found a novel method for stopping the spread of influenza viruses, a finding that could lead to a universal treatment for flu. The method involves stopping the genetic process by which the virus replicates itself. Researchers can essentially flip a switch that stops RNA in its tracks.
RNA interference (RNAi) has steadily advanced the promise of using gene silencing to block the spread of viruses or even cancer. Now the technique has proven effective in humans for the first time as a nasal spray which shuts down a common respiratory virus, New Scientist reports.
