Scientists across the United States say they cannot obtain samples of Ebola, complicating efforts to understand how the virus is mutating and develop new drugs, vaccines and diagnostics.
The problems reflect growing caution by regulators and transport companies about handling Ebola as well as... Read More
ABC Transporters are proteins that are embedded in the cell membrane and facilitate the transport across cellular barriers not only of an almost unlimited variety of toxic substances, but also of substances that are essential for life. They also play a role in the development of antibiotic resis... Read More
The global initiative to eradicate poliomyelitis through routine vaccination has helped reduce the number of cases by more than 99% in 30 years. However, major epidemics are still occurring today. Researchers have identified the virus responsible for deadly and recent outbreaks, and have sequenc... Read More
A second form of the painful chikungunya virus has appeared in Brazil—one that could more easily spread, including to the U.S.
When a mosquito-borne disease first arrived in the Western Hemisphere last year, humans were relatively lucky. The disease, which causes crippling joint pain persis... Read More
It's not a secret that the microbes living in our guts play a huge role in our well-being, or that, at least in the United States, we're doing a good job of killing them off.
But now new research finds that apes -- our closest relative -- have much more varied gut flora than humans do, and es... Read More
Developed at NYU Langone Medical Center, the “telomerator” reshapes synthetic yeast chromosome into more flexible, realistic form, redefining what geneticists can build.
NYU Langone yeast geneticists report they have developed a novel tool — dubbed “the telomerator” — that could redefine the ... Read More
Filoviruses like Ebola “edit” genetic material as they invade their hosts, according to a study published this week in mBio®, the online open-access journal of the American Society for Microbiology. The work, by researchers at the Icahn School of Medicine at Mount Sinai, the Galveston National L... Read More

A nasal vaccine in development by researchers at The University of Texas at Austin has been shown to provide long-term protection for non-human primates against the deadly Ebola virus. Results from a small pre-clinical study represent the only proof to date that a single dose of a non-injectable... Read More
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
Ever since the development of penicillin almost 90 years ago, antibiotics have remained t... Read More
A new influenza virus, discovered in pigs and later found in cows, shares common ancestry with known influenza viruses, but is distinct enough that researchers have proposed calling it Type D Influenza.

Vincent Racaniello, who studies viruses at Columbia University, says Ebola has recently become his obsession.
"I find myself reading incessantly about Ebola when I should be doing other things," says Racaniello, host of the online show This Week in Virology, which has devoted several recent p... Read More

Where does HIV hide? Antiretroviral drugs can usually control the virus, but can’t completely eliminate it. So any strategy to eradicate HIV from the body has to take into account not only the main group of immune cells the virus targets, called CD4 or helper T cells, but other infected cells as...

As will be argued below the present definition of a prokaryote is highly unsatisfactory. To give an example: a prokaryote is "a cell or organism lacking a nucleus and other membrane-enclose organelles, usually having its DNA in a single circular molecule" (Brock, Biology of Microorganisms, 10th ...

While Hollywood loves to imagine humans encountering all manner of horrific monsters in the depths of space, the greatest threat to a long-term, manned space mission may not come with tentacles, or extra mouths, or an insatiable love for human flesh. It may, in fact, be the invisible microbes t... Read More
