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

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

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

Yet another avian influenza virus, H10N8, infects humans

To the collection of avian influenza viruses known to sporadically infect humans – H5N1, H7N9, H7N2, H7N3, H7N7, H9N2, and H10N7 – we can now add H10N8, recently found in two individuals in China. Avian influenza virus H10N8 was first detected in tracheal aspirates from a 73 year old woman who w... Read More

EU worries over pig virus prompt new blood import rules

The EU Commission has agreed new rules to limit the spread of a deadly swine disease that has killed millions of piglets in the US.

Porcine Epidemic Diarrhoea virus (PEDv) has wiped out around 10% of the American herd in a year.

While the EU rejected an outright ban on live pig imports, it... Read More

Environmental Swab/Bottom of Shoe #1

On the first day of Micro class instructors have students do an environmental swab. This sample was subcultured from a student who did the bottom of their shoe. The organism, possible Bacillus sp., was tough to scrap off the agar so subculture was done by taking a small chunk of agar containi... Read More

Host genetics can contribute to lung damage in severe tuberculosis

A third of the global population is infected with the bacterial pathogen that causes tuberculosis. Most carriers control the infection and are asymptomatic, but severe forms of the disease kill over a million people every year. A new article now identifies a factor made by the host that exacerba... Read More

Bacterial Competition In Lab Shows Evolution Never Stops

Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.

That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.

Evolution is so important for biology, medicine and a genera... 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.

How zinc starves lethal bacteria to stop infection

Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.

The finding, by infectious disease researchers at the University of Adelaide and The University of Queensland, opens the way for further work to des... Read More

Epsilon toxin may trigger multiple sclerosis, research finds

Multiple sclerosis (MS), a central nervous system disease that often leads to paralysis and vision problems, affects approximately 2.3 million people worldwide and has no cure. Though no one knows what triggers MS, researchers have long suspected that a combination of genetic and environmental f... 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

Terms of Biology: The Pan-Genome

A still somewhat unfamiliar term is floating around: the pan-genome. In 2005, Tettelin et al. coined the term along with genome analyses of eight Streptococcus agalactiae strains, and Merry introduced it to this blog, some time back already. Today, a keyword search in PubMed returns roughly 200 ... Read More

Small-scale badger culls may boost spread of cattle TB

Scientists say that culling a small number of badgers risks increasing the spread of TB infection to cattle.

The research suggests that some farmers who have allegedly killed badgers on their property could be making things worse for themselves and neighbours.

The findings also indicate th... 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

Protein's "hands" enable bacteria to establish infection, research finds

When it comes to infecting humans and animals, bacteria need a helping hand.

Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More

How a microscopic team alters the course of carbon in the Atlantic ocean - Finalist in Ocean 180 Video Challenge

The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... 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
