SA vaccine cuts bacteria to size

South Africa has shown the world that a vaccine against the strains of bacteria that can cause deadly meningitis and pneumonia in children works.

A study published today in the New England Journal of Medicine, to coincide with world Pneumonia Day, records the country's success in reducing pne... Read More

Study Shows Bed Bugs Can Transmit Parasite that Causes Chagas Disease

The bed bug may be just as dangerous as its sinister cousin, the triatomine, or “kissing” bug. A new study from Penn Medicine researchers in the Center for Clinical Epidemiology and Biostatistics demonstrated that bed bugs, like the triatomines, can transmit Trypanosoma cruzi, the parasite that ...

Vaccine-resistant polio strain discovered

The global initiative to eradicate poliomyelitis through routine vaccination has helped reduce the number of cases by more than 99% in 30 years. However, major epidemics are still occurring today. Researchers have identified the virus responsible for deadly and recent outbreaks, and have sequenc... Read More

Animals steal defenses from bacteria

It's a dog eat dog world, and bacteria have been living in it for a long time. It's of no surprise that bacteria have a sophisticated arsenal to compete with each other for valuable resources in the environment. In 2010, work led by University of Washington Department of Microbiology Associate P... Read More

Worse Than The Bite

City dwellers across the U.S. might agree on one common enemy: bedbugs. But hey, not to worry, right? "Bedbugs are not known to spread diseases, but bites can be very itchy and irritating." Or so says the New York City Department of Health. But that assertion may not be true. Because a new study... Read More

Why CRISPR Doesn't Work in E. coli

We received this query:

»I enjoyed the article on your blog 'Six Questions About CRISPRs' by Merry Youle. I am an ex-lambdologist, having quit phage lambda in the early 70s and moved to GM-plants. There is one thing about CRISPR that I do not understand: Why did lambdologists not find CRISPR?... Read More

Flu virus key machine: First complete view of structure revealed

Scientists looking to understand – and potentially thwart – the influenza virus now have a much more encompassing view, thanks to the first complete structure of one of the flu virus’ key machines. Knowing the structure allows researchers to finally understand how the machine works as a whole, a... Read More

Biochemistry detective work: algae at night

Photosynthesis is probably the most well-known aspect of plant biochemistry. It enables plants, algae, and select bacteria to transform the energy from sunlight during the daytime into chemical energy in the form of sugars and starches (as well as oils and proteins), and it involves taking in ca...

Authorities Identify Highly Contagious Bird Flu Strain

Authorities found the H5N8 strain of bird flu at a poultry farm in the central Netherlands, the same highly contagious strain as found this month in Germany and which has prompted massive poultry culls in Asia.

Dutch authorities on Sunday said they had found the H5N8 strain of bird flu at a p... Read More

Peptic ulcer, cancer bacteria therapy discovery

A common ingredient in vegetable oils may help reduce infection with a bacterium that can cause stomach cancer and peptic ulcers, according to a study by UC San Diego scientists.

The ingredient, linolenic acid, killed the bacterium Helicobacter pylori in mice and reduced inflammation without ... Read More

Antibacterial Gene Transfer Across the Tree of Life

Though horizontal gene transfer (HGT) is widespread, genes and taxa experience biased rates of transferability. Curiously, independent transmission of homologous DNA to archaea, bacteria, eukaryotes, and viruses is extremely rare and often defies ecological and functional explanations. Here, we ... Read More

Quest for hepatitis B treatment wins Emerging Researcher Award

Walter and Eliza Hall Institute researcher Dr Greg Ebert has won the Bupa Health Foundation Emerging Health Researcher Award 2014 for his work on developing a new therapy for chronic hepatitis B virus (HBV) infection.

Chronic hepatitis B is a viral liver disease that affects 230,000 Australia... Read More

Schistosomas: Tropical parasite uses swim stroke not shared by any other creature

For many bacteria and parasites looking to get a load of the fresh nutritional bounty inside your body, the skin is the first and most important gatekeeper. Schistosomas, however, and burrow right on through. These waterborne blood flukes, responsible for 200 million total worldwide cases of Sch... Read More

New Type of More Problematic Mosquito-Borne Illness Detected in Brazil

A second form of the painful chikungunya virus has appeared in Brazil—one that could more easily spread, including to the U.S.

When a mosquito-borne disease first arrived in the Western Hemisphere last year, humans were relatively lucky. The disease, which causes crippling joint pain persis... Read More

The Ancient Art Of Cheese-Making Attracts Scientific Gawkers

From Swiss to cheddar, cheeses depend on the action of microbes for their flavor and aroma. But it's far from clear how these teams of microbes work together to ripen cheese.

To a cheese-maker, that's just the beauty of the art. To a scientist, it sounds like an experiment waiting to happen.

A Snippet: Thioploca

The seafloor off the coast of Chile is carpeted with bacterial mats of gigantic proportions. They cover an area as large as that of the state of Alabama. Their total weight is of the order of 100 million tons, which probably makes this the largest single species microbiome on Earth. The mats con... Read More

Would You Lick an E.Coli-Shaped Popsicle?

Designer Wei Lei poses a challenging, and fascinating question: Would you lick a delicious treat that resembles a prickly cactus or a deadly E. coli bacterium?

The Chinese designer’s collection of sweets, Dangerous Popsicles, transforms frozen sugar water into colorful spiny treats inspired b... Read More

Scientists find superbug bacteria in World War I soldier who died of dysentery

Scientists who unlocked the genetic code of bacteria grown from a soldier who died of dysentery say it revealed a superbug that was resistant to antibiotics decades before those drugs were in common use.

The discovery sheds light on the history of antibiotic resistance, which has become a glo... Read More
