Viruses are masters at mutating.
So the big concern with deadly viruses, like Ebola and hepatitis C, is that they will evolve into more dangerous forms over time.
It looks like just the opposite is happening with HIV — although it's happening slowly.
"HIV can generate any mutation in th... Read More
Scientists reveal how penicillin deals bacteria a devastating blow – work that may lead to new antibiotics.
Penicillin, the wonder drug discovered in 1928, works in ways that are still mysterious almost a century later. One of the oldest and most widely used antibiotics, it attacks enzymes th... Read More
New coatings to apply to soft cheese have been developed by researchers. These coatings are totally edible and have an antimicrobial capacity, which increases the lifespan of the cheese. These films incorporate oregano and rosemary essential oils as antimicrobial agents, and chitosan, a by-produ... Read More
Everybody and his uncle, it seems, has an idea of something that might work to cure people infected with the deadly virus.
When it comes to treatments for Ebola, there has been a nearly four-decade-long drought. Nothing in the medical arsenal attacks the virus directly. For the most part, p... Read More
Researchers at Tufts University, in collaboration with a team at the University of Illinois at Champaign-Urbana, have demonstrated a resorbable electronic implant that eliminated bacterial infection in mice by delivering heat to infected tissue when triggered by a remote wireless signal. The si... Read More
Dec. 1 has been World AIDS Day since 1988 — but though the awareness and activism around the diseases has changed drastically during the years between then and now.
To see just how much our understanding and attitudes have evolved, take a look back at TIME’s coverage of AIDS through these sev... Read More
A few months ago the U.S. Centers for Disease Control and Prevention predicted that up to 1.4 million people in Liberia and Sierra Leone could become infected with Ebola by mid-January. In a recent address to the Senate, CDC director Tom Frieden said that worst-case scenario would not pan out.

Sputum specimen from sick of fibrosis cystic can hold many microbes and yeast. This specimen sent to our laboratory Mycobacteriology of Polyclinic University of Messina for mycobacteria research, shows yeast cells with Ziehl-Neelsen stain. Read More
If you want to visit the moons of Jupiter or Saturn someday, you might end up wearing a 3-D-printed spacesuit filled with bacteria. An ordinary spacesuit wouldn't be enough to survive the crushing gravity, toxic air, and wild temperature extremes of interplanetary travel. But living, growing wea... Read More
When the World Health Organization recently named blood transfusions from Ebola survivors as its priority experimental therapy for the disease ravaging west Africa there was only one major problem: no data indicating that such transfusions work. Blood plasma from survivors contains antibodies th... Read More
Newly tenured biologist Jeroen Saeij wants to know what makes Toxoplasma gondii so unpredictable.
Toxoplasma gondii is a common parasite often spread by cats. Most people who are infected in Europe or North America show no symptoms at all, and only a few suffer from encephalitis or ocular tox... Read More
Polyethylene is one of the most popular and, unfortunately, persistent types of plastics. Bags, bottles, and packaging made from the polymer accumulate in landfills and oceans across the globe. Scientists lament that microbes can’t chew up the plastic to render it harmless. However, a new study ... Read More
The World Health Organization says it is confident that deaths from malaria could be stopped entirely.
Spread by the bites of infected mosquitoes, the illness is both preventable and treatable.
Global efforts over the last decade have already halved the number of people dying from malaria ... Read More
A deadly epidemic that could have global implications is quietly sweeping India, and among its many victims are tens of thousands of newborns dying because once-miraculous cures no longer work.
These infants are born with bacterial infections that are resistant to most known antibiotics, and ... Read More
Scientists review decades of work into bacterial proteins that transform iron and other minerals for energy and growth.
Cleaning up polluted soil and growing crops for biofuels benefit from a deeper understanding of how microbes alter subsurface minerals. Scientists at Pacific Northwest Natio... Read More
