You might feel the bite, you might not, but an infected mosquito has injected you with a parasite named Plasmodium falciparum, a single-cell protozoa that quickly takes up residence in your body. You don't feel a thing as the parasite infects your liver and begins to multiply. But then tens of thousands of parasites spill into your bloodstream and start eating their way through your red blood ...
The search for the causative agent of colony collapse—the mass die off of honey bees throughout the US and Europe—has escalated with increasing confusion lately. Everything from pesticides and stress to viruses and mites have been implicated, and some researchers think that many of these environmental factors work together to take down hives.
On October 17, 1943, a story in the New York Herald Tribune read "Many laymen — husbands, wives, parents, brothers, sisters, friends — beg Dr. Keefer for penicillin," according to the American Chemical Society.
Windborne microbes shifting in the snows of the great ice sheet of Greenland may be able to neutralize some of the industrial contaminants oozing out of the melting ice. Greenland is a long way off, and we tend to dismiss what happens there as not impacting us here — out of sight, out of mind, as they say. But the problem — and the possibility of microbial help — has significance for ...
Yes, reminiscent of the movie, "Men in Black," Conley was given a pair of Ray-ban sunglasses her first day on the job. And if you wish to be a planetary protection officer, too, you're in luck, as NASA recently posted job ad for the three-year term job, as they relocate the position to the Office of Safety and Mission Assurance, an independent ...
An older man dies of Zika. A younger man who cares for him catches Zika — but doctors cannot pinpoint how the disease was transmitted. While proximity to the patient is sufficient explanation for the rest of us, for microbe hunters, it is a medical mystery. Why? Zika is not known to transmit from person-to-person casually.
The source of the E. coli breakout has been traced to the nut-free butter, the CDC confirmed on March 21. Last week, the Montessori of Alameda preschool in Portland was the latest site of the E. coli outbreak caused by the same nationally-distributed product, after the first recall was announced.
This free energy is really a game-changer for Enceladus. The presence of molecular hydrogen shows there is the chemical potential there to support metabolic systems like methanogenic microbes. This suggests we've found a potential food source that would support the habitability of Enceladus's interior ocean.
Ecosystem changes caused by agricultural choices in Brazil are creating a dangerous microbe mix in exploding populations of vampire bats and feral pigs. Even as human-influenced climate warming is tipping the tables on ecosystems around the world, choices made by landowners in the Americas, from Mexico to Argentina, are setting the stage for emergence of diseases dangerous to humans and ...
As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists believe that gut bacteria may have a role in initiating the abnormal immune response. Now, a team of researchers from ...
