Structure of bacterial nanowire protein hints at secrets of conduction (w/ Video)

Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and min... Read More

New Drug Candidate Found for Fungal Lung Infections

On a molecular level, you have more in common with shower curtain mold or the mushrooms on your pizza than you might think. Humans and fungi share similar proteins, a biological bond that makes curing fungal infections difficult and expensive. Current costs to treat these stubborn infections can... Read More

Yeast Meets West: Yeast Cultivation (video)

In honor of the Bay Area Science Festival, a group of passionate microbrewers, scientists, and yeast cultivators make 3 original brews to compete in a blind tasting at Nerd Nite in San Francisco, California.

Botulism Bacteria Blamed for Deaths of Waterbirds on Lake Ontario

Last year, I wrote about finding the carcasses of dead loons and cormorants on the shores of a Northern Lake Michigan beach. Now officials in New York are reporting similar waterbird deaths from Type E botulism on Lake Ontario.

Sadly, finding type E botulism in waterbirds is becoming an “annu... Read More

Burglary-ring-like mechanism found in lethal Nipah virus

A team of scientists from Washington State University has discovered how one of the planet’s most deadly known viruses employs burglary-ring-like teamwork to infiltrate the human cell.

Nipah virus is so menacing that the nation’s top infectious disease experts served as consultants in the fil... Read More

More Healthcare Workers Hit by MERS

Three new cases of infection with the Middle East respiratory syndrome coronavirus (MERS-CoV) -- including two more healthcare workers -- have been reported in Saudi Arabia.

The two healthcare workers, both women, have mild symptoms after exposure to patients who had laboratory-confirmed MERS... Read More

Proteins discovered in gonorrhea may offer new approach to treatment

Researchers at Oregon State University have discovered novel proteins in, or on the surface of the bacteria that causes gonorrhea, which offer a promising new avenue of attack against a venereal disease that is showing increased resistance to the antibiotics used to treat it.

Only a single, t... Read More

In sub-Sahara, foot and mouth disease moves over short distances

You probably remember foot and mouth disease (FMD) from the 2001 outbreak in the UK that prompted the culling of over 10 million sheep and cattle, but the disease affects livestock all over the world. It's a particular problem in Africa, where wildlife that harbor the picornavirus that causes FM... Read More

Model Virus Structure Shows Why There's No Cure for the Common Cold

Rhinovirus C is believed to be responsible for up to half of all childhood colds, and is a serious complicating factor for respiratory conditions such as asthma. Together with rhinoviruses A and B, the recently discovered virus is responsible for millions of illnesses yearly at an estimated annu... Read More

A bacterium reveals the crucible of its metallurgical activity

An international consortium led by CEA researchers in collaboration with the CNRS, has succeeded in characterizing the structure and function of a protein involved in the production of magnetite nanomagnets in magnetotactic bacteria. This protein, MamP, is crucial to the metallurgical activity o... Read More

Oral Bacteria Create a ‘Fingerprint’ in Your Mouth

The bacteria in the human mouth – particularly those nestled under the gums – are as powerful as a fingerprint at identifying a person’s ethnicity, new research shows.

Scientists identified a total of almost 400 different species of microbes in the mouths of 100 study participants belonging t... Read More

Gut Microbes Respond within Days to Major Diet Changes

Microbiologists have known for some time that different diets produce different gut flora, but new research indicates that the changes take hold with startling quickness. Bacterial populations shift measurably in the first few days following a big shift in what we eat, according to a recent stud... Read More

'Bacterial raincoat' found to protect bacteria from the environment

Research led by scientists at the University of Dundee has uncovered the workings of a 'bacterial raincoat' that helps to protect bacteria from the changing environment in which they live.

Many bacteria grow in large communities called biofilms, where the cells work together and produce a sti... Read More

West African Ebola outbreak caused by new strain of disease: study

(Reuters) - An Ebola outbreak blamed for 135 deaths in West Africa in the past month was not imported from Central Africa but caused by a new strain of the disease, a study in a U.S. medical journal said, raising the specter of further regional epidemics. The spread of Ebola from a remote corner... Read More

H7N9 Influenza: History of Similar Viruses Gives Cause for Concern

The H7N9 avian flu strain that emerged in China earlier this year has been subdued for now, but it would be a mistake to be reassured by this apparent lull in infections. The virus has several highly unusual traits that paint a disquieting picture of a pathogen that may yet lead to a pandemic, a... Read More

Researchers create three-dimensional model of bacterium

Certain bacteria can build such complex membrane structures that, in terms of complexity and dynamics, look like eukaryotes, i.e., organisms with a distinct membrane-bound nucleus. Scientists from Heidelberg University and the European Molecular Biology Laboratory (EMBL) made this discovery empl... Read More

Oddly Microbial: Programmed Cell Death

The lab was a crime scene; dead and dying cells were everywhere—but did they commit mass suicide or were they murdered? The burly young post doc who discovered the corpses sat in the corner sobbing softly, his PI by his side. She was trying in vain to comfort her most promising young scientist i... Read More
