The Coming Crisis in Antibiotics

An interesting TED talk about antibiotic resistant bacteria.

Antibiotic drugs save lives. But we simply use them too much — and often for non-lifesaving purposes, like treating the flu and even raising cheaper chickens. The result, says researcher Ramanan Laxminarayan, is that the drugs will... Read More

Bacillus anthracis showing McFadyean's reaction

The slide was prepared from blood of infected animals (cattle). The smear was stained with poly-chrome methylene blue which demonstrated blue colored bacillary body and light pink colored capsule (McFadyean's reaction).

The animal had the symptoms of high fever, convulsion and sudden death. ... Read More

New Drugs May Come from Microbes in Our Guts

Plants and Microorganisms are the major sources of drugs till date. Most of these "natural products" come from a few genera of soil and marine bacteria that have long been known for their prolific chemistry. The classical process of discovering drugs from microorganisms have two drawbacks- it is... Read More

Rhizopus Tease Stain with Lactophenol Blue

This is a Tease Prep stain of the Fungal Rhizopus with Lactophenol Blue. It is seen under a microscopy at total magnification of 1000x. As shown there are pseudohyphae with conidia formed around the cells. It was the first tease prep stain that clearly shows the artistry of the fungal structure.... Read More

Mental Health May Depend on Creatures in the Gut

The microbiome may yield a new class of psychobiotics for the treatment of anxiety, depression and other mood disorders.The ongoing exploration of the human microbiome promises to bring the link between the gut and the brain into clearer focus. Scientists are increasingly convinced that the vast... Read More

The bioluminescent bacteria

Growth of the gram negative bacteria Vibrio fischeri expressing bioluminescence as a result of the symbiotic interaction with Euprymna scolopes. You can see the plate without shining and glowing in the dark. The Form is the mascot of the University of Puerto Rico at Rio Piedras campus. Read More

Liberia’s President Urges U.S. to Continue Ebola Aid

President Ellen Johnson Sirleaf of Liberia on Friday urged the United States to maintain its assistance to her country as it continues to fight to recover from the Ebola outbreak, which began about one year ago.

In a meeting at the White House with President Obama, Ms. Johnson Sirleaf asked f... Read More

Pollution is driving force behind growth of nuisance algal scums, study finds

Potentially toxic microbes which pose a threat to our drinking water have undergone a dramatic population explosion over the last 200 years as a result of pollution, research involving experts from The University of Nottingham has found. The study, published in the journal Ecology Letters, looke... Read More

Lab-on-paper developed for rapid, inexpensive medical diagnostics

A new paper-based platform has been created for conducting a wide range of complex medical diagnostics. The key development was the invention of fluid actuated valves embedded in the paper that allow for sequential manipulation of sample fluids and multiple reagents in a controlled manner to per...

Energetic immune cells are vital for fighting disease

A good immune system relies on a key ‘energy producing’ protein in immune cells to develop immunity to vaccines and disease, an international team of scientists has found.

The protein, called HuR (human antigen R) is critical for controlling metabolism in B cells, which make antibodies that a... Read More

Newly discovered hormone mimics the effects of exercise

Scientists have discovered a new hormone that fights the weight gain caused by a high-fat Western diet and normalizes the metabolism -- effects commonly associated with exercising. When tested in mice, the hormone blocked the negative health effects of eating a high-fat diet. Read More

Attention, All Scientists: Do Improv

Martha Furie stormed into the room and huffily sat down in a chair.

“Well, you know, I’ve been working really hard, studying Lyme disease,” she said, her voice tinged with disdain, to the woman sitting in the next chair. “It’s been a long process. It’s hard to talk about it.”

The other wom... Read More

Microphotograph of Penicillum corylophilum at 400 magnification

This filamentous fungus was isolated from soil of a petroleum hydrocarbon polluted ship breaking yard. It can degrade some linear petroleum hydrocarbons, like kerosene, diesel and octane. Read More

First detailed microscopy evidence of bacteria at the lower size limit of life

Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based descriptio... Read More

An aggressive form of HIV uncovered in Cuba

Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus. One such recombinant variant observed in patients in Cuba appears to be much ... Read More

Funny art

Image of antifungal potential of Lactobacillus isolates against Geotrichum spp., Aspergillus spp. and Penicillum spp.. While Reviewing my results I could see an interesting thing that it resembles as like aliens face. Read More

Michael Goldberg, Thirty Years The ASM's Executive Director

You must have heard it said that no one is indispensable to an institution. Maybe so, but such truths come in degrees. Every so often someone comes along who makes a genuine difference in how an organization functions. I turn here to Michael Goldberg, who thirty years ago began a most distinguis... Read More

Link identified between virus recognition, destruction in bacterial immune system

An immune system that helps bacteria combat viruses is yielding unlikely results such as the ability to edit genome sequences and potentially correct mutations that cause human disease.

University of Georgia researchers Michael and Rebecca Terns were among the first to begin to study the bact... Read More
