Laser tool speeds up detection of Salmonella in food products

Purdue University researchers have developed a laser sensor that can identify Salmonella bacteria grown from food samples about three times faster than conventional detection methods.

Known as BARDOT (pronounced bar-DOH'), the machine scans bacteria colonies and generates a distinct black and... Read More

Predicting the virulence of MRSA from its genome sequence

Microbial virulence is a complex and often multifactorial phenotype, intricately linked to a pathogen’s evolutionary trajectory. Toxicity, the ability to destroy host cell membranes, and adhesion, the ability to adhere to human tissues, are the major virulence factors of many bacterial pathogens... Read More

Scientists Turn Dr. Frankenstein, Re-Write Bacteria’s Entire Genome

It may sound like science fiction, but researchers at Yale and Harvard have taken the first steps towards a Dr. Frankenstein-type reality, by fundamentally changing the genetic code of an organism.

The scientists were able to rewrite the genetic alphabet of the common bacteria E.coli, creatin... Read More

Biotransformation of Enniatins from Fusarium Fungi in a Food Safety Perspective

Mould species of the genera Fusarium and Altenaria are considered the most important threats to Norwegian grain cereals because they produce toxins which can be a potential risk to food safety. F. avenaceum, the fungi most frequently isolated from Norwegian grain, produces enniatins which have b... Read More

Computing with Slime

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors....

Lassa Fever Reported in U.S. Traveler to West Africa

A Minnesota man who returned from a trip to West Africa has been diagnosed with Lassa fever, a severe and sometimes deadly viral disease rarely seen in the United States, health officials said.

The man, who was hospitalized with fever and confusion on March 31, was confirmed to have Lassa fev... Read More

UC Davis Researchers Find How Viral Infection Disrupts Neural Development in Offspring, Increasing Risk of Autism

Activating a mother’s immune system during her pregnancy disrupts the development of neural cells in the brain of her offspring and damages the cells' ability to transmit signals and communicate with one another, researchers with the UC Davis Center for Neuroscience and Department of Neurology h...

New botox super-toxin has its details censored

A new type of botulinum toxin – the deadliest substance known – has been discovered. Because it does not yet have an antidote, the DNA sequence behind it has been withheld from public databases. This is the first time a sequence has been kept secret over security concerns.

Injecting a mere 2 ... Read More

H7N9 influenza strain resistant to antivirals, but tests fail to identify resistance

Some strains of the avian H7N9 influenza that emerged in China this year have developed resistance to the only antiviral drugs available to treat the infection, but testing for antiviral resistance can give misleading results, helping hasten the spread of resistant strains. The authors of a stud... Read More

Are tiny microbes outwitting us to steal our food?

It's long been know that microbes are to blame for food going off and becoming rotten but in the late 1970's, Dan Janzen of the University of Pennsylvania, and a winner of ecology's version of the Nobel Prize, suggested that making something rotten may be to the advantage of the microbes living ...

Antibacterial products fuel resistant bacteria in streams and rivers

Triclosan – a synthetic antibacterial widely used in personal care products – is fueling the development of resistant bacteria in streams and rivers. So reports a new paper in the journal Environmental Science and Technology, which is the first to document triclosan resistance in a natural envir... Read More

Paper device spots antibiotic-resistant bacteria

Scientists in Canada have developed a paper-based device that checks if bacteria are resistant to certain antibiotics. The simple system could help users in remote areas pick the most appropriate treatment for bacterial infections.

World changing technology enables crops to take nitrogen from the air

A major new technology has been developed by The University of Nottingham, which enables all of the world’s crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.

Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital fo... Read More

Methane-Munching Microorganisms Meddle with Metals

On the continental margins, where the seafloor drops hundreds of meters below the water’s surface, low temperatures and high pressure lock methane inside ice crystals. Called methane hydrates, these crystals are a potential energy source, but they are also a potential source of global warming if... Read More

Compound stymies polyomaviruses in lab

There is no approved medicine to treat polyomaviruses, which afflict people with weakened immune systems, but scientists have found that a chemical compound called Retro-2 is able to reduce significantly the infectivity and spread of the viruses in lab cell cultures. Now they are working to impr... Read More

'Citrus greening' bacteria devastating world's orange crop

A glass of orange juice in the morning is something many of us take for granted. But that might soon change thanks to a citrus disease affecting every major orange-growing region in the world.

The world's orange crop is being threatened by "citrus greening," a bacterial infection carried by a... Read More

Saudi Arabia reports 1 more death from new virus

Saudi Arabia says one more person has died from a new respiratory virus related to SARS, bringing to 55 the number of deaths in the kingdom at the center of the outbreak.

The Health Ministry said Sunday that the 37-year-old man died in Riyadh. He was among 130 people who have been infected wi... Read More

Oman says first MERS-coronavirus sufferer dies in hospital

Oman's first MERS coronavirus patient died in hospital on Sunday from lung failure, state news agency ONA said.

The Middle East Respiratory Syndrome Coronavirus (MERS-CoV), which can cause coughing, fever and pneumonia, emerged in Saudi Arabia last year and has been reported in Qatar, France,... Read More

New research reveals how bacteria construct tiny flagella ‘nanomachines’ outside the cell

Cambridge scientists have uncovered the mechanism by which bacteria build their surface propellers (flagella) – the long extensions that allow them to swim towards food and away from danger. The results, published this week in the journal Nature, demonstrate how the mechanism is powered by the s... 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
