To meet the common challenge of water contaminated with E.coli, the study team created what they call "Janus microbots," to collect and kill E. coli while they swim through contaminated water. "Janus" is a deity from Roman mythology. Associated with time, beginnings and endings, and before and after, Janus is always depicted with two faces.
Researchers are targeting a key protein involved in this process, in an attempt to stop the parasite. They found that interfering with this protein slows the escape of the parasite from red blood cells, reducing the rate of infection and making it easier for the body to shut it down. The research findings were published July 6 in PLOS Pathogens.
By genetically-modifying these same parasites, researchers in Seattle recently created a vaccine that appears to be safe and effective in generating an immune response to malaria in a small study of human volunteers. The work is part of a global effort to eliminate the suffering caused by malaria through improved testing, treatment, vector ...
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.
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.
It's about time people acknowledged that judging drug users would do nothing productive to help them. In the US this week, two new programs are launching that should help addicts be a little safer: Walgreens Healthcare Clinic will begin offering to test for HIV and hepatitis C next week, and Las Vegas is set to introduce clean syringe vending machines to stop infections from dirty needles.
The number of Legionnaires' cases in New York over the last couple weeks has led to concern and recommendations of caution for those at risk. The bacteria grows in water, especially in larger water systems like those at hotels. Conditions are improving for its growth as temperatures rise for summer. A warm environment is more hospitable for Legionella and risky for people.
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. From Earth, across the solar system ...
The bacteria in our gut — a community called the gut microbiome — have been in the spotlight a lot lately. What we're learning about how our intestinal bacteria adapt and grow with our bodies could help athletes perform better, according to researchers starting a company focused on creating probiotics that mimic athletes' microbiomes.
