Antibiotics may help Salmonella spread in infected animals, scientists learn

Some people infected with pathogens spread their germs to others while remaining symptom-free themselves. Now, investigators at the Stanford University School of Medicine believe they may know why.

When the scientists gave oral antibiotics to mice infected with Salmonella typhimurium, a bacte... Read More

Bacterial Hopanoids – The Lipids That Last Forever

The world of lipids does not always gets its due. Their oleaginous charm is not always appreciated, as we said here before. For example, have you heard of hopanoids? They are made by some bacteria and are an unusual kind of polycyclic lipids that resemble steroids, but with an extra ring. Just l... Read More

A recent study of biofilm formation in an archaeon revealed a fascinating form of social motility

A study of biofilm formation in the model haloarchaeal species Haloferax volcanii has led to the observation of a fascinating example of coordinated social motility (and of cellular differentiation and gene transfer). Haloferax volcanii was first isolated from Dead Sea sediment in 1975, but was ... Read More

Divide and Conquer: novel trick helps rare pathogen infect healthy people

New research into a rare pathogen has shown how a unique evolutionary trait allows it to infect even the healthiest of hosts through a smart solution to the body’s immune response against it.

Scientists at the University of Birmingham have explained how a particular strain of a fungus, Crypto... Read More

Evolution of extreme parasites explained by scientists

Extreme adaptations of species often cause such significant changes that their evolutionary history is difficult to reconstruct. Zoologists have now discovered a new parasite species that represents the missing link between fungi and an extreme group of parasites. Researchers are now able to und... Read More

Chromosome Organization the Pseudomonas Way, Part 2

Studying chromosome organization in bacteria. Over the last twenty years, molecular biologists developed and refined a downright cute method to study bacterial chromosome organization in live cells. Briefly, a cluster of binding sites for a DNA-binding protein is introduced at a chosen locus of ... Read More

Rousselle et al (2) incorporation of chromogenic or fluorogenic hexosaminidase substrates... Read More

Fine Reading: Trans-kingdom Cross Talk – Small RNAs on the Move

We have lived with the discovery of small RNAs as regulatory molecules for nearly 30 years, so for most readers of this blog this is old hat. But some of us oldsters are still reeling from the novelty and importance of the findings. It seems odd that a subject of this significance, one that has ... Read More

Shaking up cell biology: Researchers focus in on decades-old mitochondrial mystery

Elvis did it, Michael Jackson did it, and so do the mitochondria in our cells. They shake. While Elvis and Michael shook for decades before loud and appreciative audiences, mitochondrial oscillations have quietly bewildered scientists for more than 40 years.

Now, a team of scientists at Natio... Read More

Brazil releases 'good' mosquitoes to fight dengue fever

Brazilian researchers in Rio de Janeiro have released thousands of mosquitoes infected with bacteria that suppress dengue fever.

The hope is they will multiply, breed and become the majority of mosquitoes, thus reducing cases of the disease.

The initiative is part of a programme also takin... Read More

Middle-Aged Adults Were More Susceptible to the Flu Last Year because of a New Viral Mutation

A team of scientists, led by researchers at The Wistar Institute, has identified a possible explanation for why middle-aged adults were hit especially hard by the H1N1 influenza virus during the 2013-2014 influenza season. The findings, published in the Proceedings of the National Academy of Sci... Read More

Superbugs should scare you more than Ebola in US

The first case of Ebola in the United States was announced today, with a patient in Dallas who traveled to the US from Liberia. The resultant hysteria and xenophobia prompts this reminder. There is NO need to panic.

Ebola is NOT transmitted before a patient develops symptoms. Ebola is transmi... Read More

Three Irish Teens Win Google Science Fair Using Bacteria to Grow Food

A trio of Irish high-schoolers nabbed the top prize in this year's Google Science Fair with a project that speeds up crop growth by tapping into the naturally cozy relationship between soil microbes and plants.

After 11 months of experiments, the three 16-year-olds—Ciara Judge, Émer Hickey, a... Read More

Amphibian communities collapse in wake of viral outbreak

Two closely related viruses that have been introduced to northern Spain in recent years have already led to the collapse of three different species of amphibian -- the common midwife toad, the common toad, and the alpine newt -- in the protected area of Picos de Europa National Park. In all, six... Read More
