New ways of cultivating valuable marine microorganisms

A four-year EU-funded project has identified new ways of cultivating marine microorganisms and screening them for potentially useful marine bio-compounds. This could have implications for the healthcare, cosmetics and pharmaceutical industries, which are just a few of the sectors that are eager ... Read More

Muddled about MERS? Here’s A Quick Guide

While I was working on the “H1N-What?” post, I also knew there would soon be questions about MERS (Middle East Respiratory Syndrome), just as there were about SARS. So here are the essentials of what we know and don’t know about MERS—which has just been reported in the U.S.—as well as intriguing... Read More

Research shows bacteria can combat dangerous gas leaks

Bacteria could mop up naturally-occurring and man-made leaks of natural gases before they are released into the atmosphere and cause global warming - according to new research from the University of East Anglia.

Findings published today in the journal Nature shows how a single bacterial strai... Read More

How a plant beckons the bacteria that will do it harm

A common plant puts out a welcome mat to bacteria seeking to invade, and scientists have discovered the mat's molecular mix. The study published this week in the Proceedings of the National Academy of Sciences reveals new targets during the battle between microbe and host that researchers can ex... Read More

Microgravity research helping to understand the fungi within

(Phys.org) —You may not recognize it by name, but if you have ever had a child with a diaper rash, that child was likely a host to Candida albicans (C. albicans). This unwelcome "guest" can be hard to control, as it can potentially lead to serious illness in humans with weakened immune systems. ... Read More

Nutrient-absorbing surface’s assembly revealed: study

Vanderbilt University researchers have now discovered how intestinal cells build this specialized structure, which is critical for absorbing nutrients and defending against pathogens. The findings, published April 10 in the journal Cell, reveal a role for adhesion molecules in brush border assem... Read More

Insight into pathogenic fungus

The fungal pathogen Candida albicans causes yeast infections, diaper rashes and oral thrush, and is the most common fungal pathogen to infect humans. Researchers have identified a protein that the fungus uses to defend itself against the human body. Another concern with the fungus is that it can... Read More

Dairy scientist targets heat-resistant microbes

Corralling desperados with names like bacillus and paenibacillus will require ingenuity and an arsenal of weapons. These outlaws aren't rustling cattle—they're making milk sour and cheese soft and crumbly.

For more than a century, milk has been heated to kill any bacteria or pathogens that ca... Read More

Adhering To The 'Replicon Model' The Sloppy Way

Sixty years ago Jacob, Brenner and Cuzin devised their 'Replicon Model', inspiring and useful guideline for replication research ever since. According to the model, a 'Replicon' is a genetic element replicated from a single 'Replicator'—replication origin, in modern terms—and replication is trig... Read More

Brewing yeasts reveal secrets of chromosomal warfare and dysfunction

Using two yeasts that have been used to brew tea and beer for centuries, researchers at Fred Hutchinson Cancer Research Center have revealed how reproductive barriers might rapidly arise to create species boundaries. Schizosaccharomyces pombe has been used to brew beer in Africa, whereas its clo... 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

From the archives: life at 90°C

Prokaryotes are by far the most successful superkingdom in terms of both biochemical diversity and the variety of environments conquered. Bacteria can be found living in all kinds of adverse conditions; from high alkaline lakes, to below freezing temperature, to hot volcanic vents which in some ... Read More

The bug that lost a few genes to become Black Death

About 6,000 years ago, a bacterium underwent a few genetic changes. These allowed it to expand its habitat from the guts of mice to that of fleas. Such changes happen all the time, but in this particular instance the transformation eventually resulted in the Black Death that wiped out a third of... Read More

Liquids


Liquids are capable of forming a gas-liquid interface: maintenance of the surface requires adequate pressure in the gas. Adequate in this instance means a gas pressure greater than the vaporisation pressure in the liquid. The gas pressure... Read More

Facilitation of horizontal transfer of antimicrobial resistance by transformation of antibiotic-induced cell-wall-deficient bacteria

It is universally accepted that the use of antibiotics will lead to antimicrobial resistance. Traditionally, the explanation to this phenomenon was random mutation and horizontal gene transfer and amplification by selective pressure. Subsequently, a second mechanism of antibiotic-induced antimic... Read More

Six to Tango

One genome at a time can be exciting, but two even more so. I’m not entirely sure why this is, although it may explain our fascination with sex. And what if more than two entities were involved? What if the intimacy were not just between two individual organisms, but between a greater number of ... Read More

Cells' powerhouses were once energy parasites: Study upends current theories of how mitochondria began

Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants -- and first acted as energy parasites in those cells before becoming beneficial, according to a new study.
