Experiments with the most dangerous human viruses, such as Ebola virus and Lassa virus, are carried out in biosafety level 4 (BSL-4) laboratories. Since visiting the Northeast Infectious Diseases Laboratory BSL-4 and releasing the documentary video Threading the NEIDL, I was given the opportunit... Read More
Common gut bacteria prevent sensitization to allergens in a mouse model for peanut allergy, paving the way for probiotic therapies to treat food allergies.
The presence of Clostridia, a common class of gut bacteria, protects against food allergies, a new study in mice finds. By inducing immun... Read More
Now about the term Talmudic.
Exposed for 3 minutes outdoors in the gymnasium of the Inter American University of Puerto Rico. Medium used for fungi PDA. Culture medium used for bacteria TSA. Incubated at 37 degrees for 48 hours. Read More
When viruses such as influenza and Ebola jump from one species to another, their ability to cause harm can change dramatically, but research from the University of Cambridge shows that it may be possible to predict the virus's virulence by looking at how deadly it is in closely-related species Read More
An immune cell protein, ID2, is critical for the maintenance of healthy gut microbiota and helps these good bacteria fight off harmful bacteria, report scientists from the University of Chicago. The study, published in Immunity on April 21, suggests that novel therapeutics or microbiota transpla... Read More
Pampering leafcutter ants with fragrant rose petals and fresh oranges may seem an unlikely way to rescue modern medicine, but scientists at a lab in eastern England think it's well worth trying.
As the world cries out for new antibiotics, researchers at the John Innes Center (JIC) in Norwich ... Read More
A large community of microorganisms calls the human digestive tract home. This dynamic conglomerate of microscopic life forms - the gut microbiome - is vital to how people metabolize various nutrients in their food, how their immune systems react to infection, and how they respond to various med...

Scientists say they have discovered a natural compound from bacteria that may prove to be a potent new antibiotic. This news comes at a time when many current antibiotics are losing their oomph — germs become resistant to them.
The new compound is especially intriguing because it appears that... Read More
In the world of health and medicine, the word tobacco usually brings to mind cancer, emphysema and heart disease. But in recent years the plant's tarnished reputation is getting a makeover from the development of pharmaceuticals through an effective, swift and cost-cutting technique that has bee... Read More
Humans are increasingly dependent on algae to suck up climate-warming carbon dioxide from the atmosphere and sink it to the bottom of the ocean. Now, by using a combination of satellite imagery and laboratory experiments, researchers have evidence showing that viruses infecting those algae are d... Read More
For hospital workers an outbreak of harmful bacteria in the wards is a nightmare, but what gives bacteria nightmares?
Perhaps the prospect of being eaten alive by a kind of viral parasite called a bacteriophage (bacteria eater): unlike antibiotics, which some bacteria have evolved a resistanc... Read More
Genetically manipulated yeast can produce morphine, which could help get around the problems with poppy crops, which include climate, disease and war. Karen Hopkin reports.
Yeast. They already participate in producing some of the most popular pain-killing substances around: beer and wine. Now... Read More
Rubella, a disease with terrible consequences for unborn children, has finally been eliminated from the Americas, a scientific panel set up by global health authorities announced Wednesday. Read More
Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More
Multiple sclerosis (MS) is an electrical disorder, or rather one of impaired myelin, a fatty, insulating substance that better allows electric current to bolt down our neurons and release the neurotransmitters that help run our bodies and brains. Researchers have speculated for some time that th... Read More
Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube.
Using this method, scientists learned that populations ... Read More
Explorations of how the microscopic communities that inhabit the human body might contribute to health or disease have moved from obscure to ubiquitous. Over the past five years, studies have linked our microbial settlers to conditions as diverse as autism, cancer and diabetes.
This excitemen... Read More
I am a retired computer programmer and also a free market libertarian. I listened to a recent podcast where the subject of mandatory hand washing by food workers was tossed around. I would like to present a few more of the free marke... Read More
Household pets can transmit infection to people, especially those with weak immune systems, young children, pregnant women and seniors, according to an article in CMAJ (Canadian Medical Association Journal). Health care providers and pet owners should be aware of this risk to prevent illness in ... Read More
