Scientists Figure Out How Microbes Make Wine Good

Yeast aren’t the only microbes that help turn boring grapes into the delicious, seductive, complex, confusing, subtle, and totally splendiferous tonic known as wine. In addition to those well-known fermenters, a type of bacteria called Oenococcus oeni (for reasons that will be obvious to oenophi... 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

Investigating the Cheese Microbiome

We need to understand how diverse communities of microbes interact, but doing so in the gut is hard. Why not turn to a model system, where diverse microbial communities interact, but in an environment that’s easier to study? We have a long history of using model systems in biology – the mice I m...

Rare byproduct of marine bacteria kills cancer cells by snipping their DNA

Yale University researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.

The molecule, lomaiviticin A, was previously shown to be lethal to cultured human cancer cells, but the mech... 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

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

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

Source of Justian Plague Sequenced?

In a fascinating story that was presented on NPR by Nell Greenfieldboyce we learn that the source of the Justian Plague (541-543AD) was recently identified by sequencing blood extracted from the dental pulp of the teeth associated with two skeletons recovered from Munich. For many years it was... Read More

How do they make it work? Genomic Revelations on a Bacterial Consortium

Do you ever look at a couple and wonder… ‘Why are they together? What does X see in Y. I just don’t get it. Is X in it only for the money’? Who doesn’t at times ponder about such matters? There’s practically an entire economy based on it. However, you didn’t find this article while waiting to ... Read More

Natural History is Dying, and We Are All the Losers

A few weeks ago, I came across a new paper in BioScience called “Natural History’s Place in Science and Society” that contained the following graph.

On the right axis and indicated by the line surrounded by dots is the proportion of introductory biology texts devoted to natural history since ... Read More

Magical Monsoon:rAiNs and Geosmin

A Geosmin Story:
A Musty / Muddy smell - the earthy odour after a heavy spatter of rain is aesthetic to senses.
A poet sitting in such ambiance lets his thoughts to wander randomly and comes out with a sweet piece of write up.
An Artist can do wonders on his canvas flowing with the mood.
Man... 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

ICAAC 2012 - Emergence of Animal-Origin H3N2 Influenza

Public health officials will provide the latest update on the H3N2, the new strain of influenza that appears to have jumped from swine to humans and has already infected nearly 300 pe... Read More

ICAAC 2012 - Do Cranberries Prevent UTIs?

There is a long history of anecdotal evidence to suggest that cranberries and other alternative therapies to long-term antibiotics can prevent recurrent urinary tract infections but are they really as effective as antibiotics or even a viable alternative for people who do not want to take ant...

A Letter to STC from Julian Davies

Bravo Randy Schekman!

I strongly support your comments on the tyranny of "impact factors" and I will be pleased to join in efforts to prevent the misuse of these ratings.

Impact Factors have become a symbol of terror for scientists in all disciplines and their use in promotion and other ... 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

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

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
