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

Stopping malaria transmission: A Virginia Tech biochemist is out for blood

Fighting malaria in today’s world will require a new, targeted approach, and Virginia Tech researchers are out for blood.

The parasites responsible for the mosquito-borne infectious disease are increasingly resistant to current drug approaches, and almost half of the world is at risk of cont... 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

State's Flu Shot Rule for Preschoolers Helped

A Connecticut law requiring flu shots for children entering preschool or daycare has reduced flu-related hospitalizations of young children by 12 percent, according to a new study. The jump in flu vaccinations of young children -- to 84 percent in 2012-2013 from about 68 percent in 2009-2010 -- ... Read More

Researchers Identify Protein That Helps Control Common Viral Infection

Infectious disease specialists at the Johns Hopkins Children’s Center have identified a protein that regulates the body’s immune response to cytomegalovirus (CMV), a common pathogen that causes lifelong infections and can lead to devastating illness in newborns and those with weakened immune sys...

Microbe, Enzyme or Mineral? A Riddle in the Soil

When most people look at soil, they just see dirt. When I look at soil, I see billions of microorganisms crawling atop one another, consuming the dead in a feasting frenzy that stops for nothing save a deep freeze. I see microbes and their enzymes, the digestive juices that break down, transform... Read More

Scientists discover how a killer fungus attacks HIV patients

Researchers have discovered that a type of white blood cell carries a deadly fungus into the brains of HIV positive patients, causing meningitis which kills more than 600,000 people a year. The discovery could lead to more effective ways of tackling the deadly fungus as it infects the human body... 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

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

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...

Immune cell ‘defenders’ could beat invading bacteria

An international team of scientists has identified the precise biochemical key that wakes up the body’s immune cells and sends them into action against invading bacteria and fungi.
The patented work, published in Nature today, provides the starting point to understanding our first line of defen... Read More

Wolbachia Genome Reduction, Phage WO, and Reproductive Parasitism

Abstract:

Wolbachia are maternally transmitted endosymbionts that often alter their arthropod hosts’ biology to favor the success of infected females, and they may also serve as a speciation microbe driving reproductive isolation. Two of these host manipulations include killing males outrigh... Read More

Reprogrammed Bacteria Build Self-Healing ‘Living Materials’

How handy would it be if, instead of taking your broken circuit board to the Genius Bar (again), you could just prompt it to heal itself? That’s the futuristic possibility researchers have recently inched ever so slightly toward, with the development of hybrid “living materials” made from bacter... 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

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

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

Farmers Fight Poisonous Wheat Fungus with Cleaning and Waiting

Dave Wiechert of Nashville, Illinois, does good business most years cleaning seed for farmers in preparation for planting season. But this year, Wiechert is doing big business after harvest: cleaning fungus off wheat so farmers can sell it.

The "head scab" fungus can produce vomitoxin, a chem... Read More

Nibbled to Death: U.Va. Researchers Discover New Way Human Cells Are Killed

Researchers at the University of Virginia School of Medicine studying a potentially deadly parasitic infection have discovered a previously unknown way that human cells are killed, with the parasitic amoeba essentially nibbling cells to death – as a piranha might attack its prey.

Until now, r... Read More

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
