'Transformer' protein provides new insights into Ebola virus disease

A new study reveals that a protein of the Ebola virus can transform into three distinct shapes, each with a separate function that is critical to the virus's survival. Each shape offers a potential target for developing drugs against Ebola virus disease, a hemorrhagic fever that kills up to 9 ou... Read More

New material improves wound healing, keeps bacteria from sticking

As many patients know, treating wounds has become far more sophisticated than sewing stitches and applying gauze, but dressings still have shortcomings. Now scientists are reporting the next step in the evolution of wound treatment with a material that leads to faster healing than existing comme... Read More

The Way You’re Born Can Mess With the Microbes You Need to Survive

Throughout the animal kingdom, mothers transfer microbes to their young while giving birth. Different species of tadpoles acquire specific skin bacteria from mother frogs even though they all live in the same pond with the same bacterial background. Emerging chicken eggs get inoculated with micr... Read More

Hitchhiking virus confirms saga of ancient human migration

A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.

The virus under study, herpes simplex virus type 1 (HSV-1), usual... Read More

Uncovering the secret world of the Plastisphere

Scientists are revealing how microbes living on floating pieces of plastic marine debris affect the ocean ecosystem, and the potential harm they pose to invertebrates, humans and other animals. New research being presented here today delves deeper into the largely unexplored world of the “Plasti... Read More

Diversity of Antiviral Bacteria Discovered

Wolbachia, a symbiont that resides naturally up to 70% of all insect species, are probably the most prevalent infectious bacteria on Earth. In 2008 Luis Teixeira, now a principal investigator at the Instituto Gulbenkian de Ciência, and other scientists have discovered that Wolbachia can protect ... Read More

E. coli Keeps Its Powder Dry

Whether inhabiting soil, fresh water, or marine ecosystems, bacteria are constantly facing the threat of numerous and effective predators such as protists, nematodes, or phages. To defend against such predation, bacteria have evolved a number of strategies, including getting larger in size, movi... Read More

ASM GM 2014 - Bacteria in Urine Could Cause Overactive Bladder

Contrary to popular belief, urine is not sterile and the bacteria in it may be associated with overactive bladder (OAB) in some women. Presenters will discuss their research ... Read More

Soil bacterium causes biofuel breakdown

Biofuels made from plant materials—also known as lignocellulosic biofuels—have promise as a source of sustainable alternative fuels thanks to soil bacterium known as Enterobacter lignolyticus SCF1. SCF1 degrades lignin and decomposes plant cell walls, allowing access to the cellulose sugars that... Read More

MDR-TB: A Global Threat

In Pakistan prevalence and drug resistance of TB is on the rise. Late diagnosis and lack of resources are making the situation worse. In such a scenario molecular techniques such as PCR and hybridization would help in early diagnosis of TB and MDR TB leading to commencement of treatment at the r... Read More

It’s Funnier When You’re Right

The mystery of alcoholic fermentations was uncovered in the first half of the 19th century by Cagniard-Latour (1837) in France, and Schwann (1837) and Kützing (1837) in Germany, based on microscopic studies but not without controversy. The great German organic chemist Justus Liebig did not like ... Read More

Rotavirus Activates Lymphocytes from Non-Obese Diabetic Mice by Triggering Toll-Like Receptor 7 Signaling and Interferon Production in Plasmacytoid Dendritic Cells

It has been proposed that rotavirus infection promotes the progression of genetically-predisposed children to type 1 diabetes, a chronic autoimmune disease marked by infiltration of activated lymphocytes into pancreatic islets. Non-obese diabetic (NOD) mice provide a model for the human disease.... Read More

Bacterial Gut Biome May Guide Colon Cancer Progression

Colorectal cancer develops in what is probably the most complex environment in the human body, a place where human cells cohabitate with a colony of approximately 10 trillion bacteria, most of which are unknown. At the 2014 American Association for Cancer Research Annual Meeting in San Diego, re... Read More

Staph Germs Hide Out In The Hidden Recesses Of Your Nose

Otherwise innocuous bacteria can cause deadly infections when people have surgery or fall ill. To prevent trouble, patients sometimes have their bodies scrubbed clean of Staphylococcus aureus. But it doesn't always work.

That may because the germs thrive in upper recesses of the nose, far fro... Read More

Florida citrus growers worry that deadly bacteria will mean end of orange juice

The sprawling citrus orchard that Victor Story toured recently sure looked like a steal at $11,000 an acre. The investors who owned it were going to lose money, and potential buyers such as Story might have stood to reap a handsome reward.

But as he bumped along the 40 acres of groves in a la... Read More

Gastroenteritis Hospitalizations in Adults Reduced Since Start of Infant Rotavirus Vaccination

“Implementation of infant rotavirus vaccination in 2006 has substantially reduced the burden of severe gastroenteritis among U.S. children younger than 5 years,” write Paul A. Gastanaduy, M.D., M.P.H., of the Centers for Disease Control and Prevention, Atlanta, and colleagues. “Whether indirect ... Read More

Warmer temperatures push malaria to higher elevations

Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year. University of Michigan ecologists and their colleagues are reporting the first har... Read More

Cordyceps: attack of the killer fungi

The video shows an ant that is infected with a fungus called Ophiocordyceps unilateralis, which has both infiltrated and commandeered its body. While it devours the ant alive, it also sends its zombified host scurrying up a plant stem. The ant walks along the underside of a leaf and vigorously l... Read More

A Snippet: Antibiotics In The Nursery

You have heard of the leaf-cutting ants1 that meticulously cultivate "their" fungi2 which provide them with nutrients, and that, in addition, host actinobacteria which prevent bacterial and fungal infections of their fungi as well as their own infection by an entomopathogenic fungus3 Metarhizium...
