Yeast reveals secret of ‘hitchhiker’ mutations

It takes a “group effort” of genetic mutations to give organisms the best shot at evolutionary survival, a new study suggests.

Evolution occurs when an individual experiences a spontaneous beneficial mutation in its genome that improves its ability to adapt to its environment. The common view... Read More

Women are more vulnerable to infections

Public-health officials discount role of sex in people's response to flu and other infections.

Sabra Klein came to the annual meeting of the Society for the Study of Reproduction this week armed with a message that might seem obvious to scientists who obsess over sex: men and women are differ... Read More

Molluscs vs. bacteria: a new finding on marine natural products biosynthesis

The gastropod mollusc Scaphander lignarius —a marine invertebrate found in North Atlantic and Mediterranean water— is the first organism, besides bacteria, in which the biosynthesis of lignarenones, organic molecules involved in organism’s chemical defence, has been identified. This is one of th... Read More

Where ‘Nightmare Bacteria’ Came From, And How Our Inattention Helped Them Emerge

Cast your minds back a few months ago, to when the director of the US Centers for Disease Control and Prevention announced, “We have a very serious problem” with “nightmare bacteria,” and the chief medical officer of the United Kingdom backed him up a few days later, describing a “ticking time b...

Are pathogens conspiring against you? Bi-directional signaling between different streptococcal species

Are pathogens conspiring against you? Pathogenesis just got a little more complicated. In their study in mBio this week, Cook et al. show that different pathogenic species of streptococci can respond to one another's quorum sensing signals, an indication that they may well coordinate their actio...

USF-led study suggests some chronic fatigue syndrome patients may benefit from anti-herpesvirus drug treatment

Many experts believe that chronic fatigue syndrome (CFS) has several root causes including some viruses. Now, lead scientists Shara Pantry, Maria Medveczky and Peter Medveczky of the University of South Florida’s Morsani College of Medicine, along with the help of several collaborating scientist...

High pressure lets herpes virus ‘shoot’ DNA

Researchers have discovered that herpes viruses are like tiny powder kegs waiting to explode—findings that may lead to new therapies and prevention drugs.

For more than 20 years scientists suspected that herpes viruses were packaged so full of genetic material that they built up an internal p... Read More

TWiM 60 Letters

I’m reeling from this episode!! The symbiosis, the web of life, the energies, chemicals, organisms of
evolutionary progression shaping our world naturally and by human intervention with unknown consequences, then you all tie it to the brain microbio... Read More

Is a common food fungus worsening the AIDS epidemic?

A type of fungus coating much of the stored corn, wheat, rice and nuts in developing countries may be quietly worsening the AIDS epidemic, according to a paper published today in the World Mycotoxin Journal.

Kept in sacks piled in barns and warehouses, food stores in countries near the equato... Read More

Newly Discovered Marine Viruses Offer Glimpse Into Untapped Biodiversity

Studying bacteria from the Baltic Sea, UA researchers have discovered an entire array of previously unknown viruses that barely resemble any of the known bacteria-infecting viruses.

Researchers of the University of Arizona's Tucson Marine Phage Lab have discovered a dozen new types of unknown... Read More

Purple Bacteria on Earth Could Survive Alien Light

Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer than most other organisms on the planet. University of Miami (UM) physicis... Read More

These Bacteria Are Wired to Hunt Like a Tiny Wolf Pack

You wouldn’t know it, but there is an elaborate stealth communication network in the Earth beneath your feet. This smart web acts like a superorganism, fortifying defensive capabilities and coordinating deadly attacks on unsuspecting targets. But it’s not run by the NSA, the CIA, or the military...

MRSA: Farming up trouble

Microbiologists are trying to work out whether use of antibiotics on farms is fuelling the human epidemic of drug-resistant bacteria.

The sight of just one boot coming through the doorway cues the clatter of tiny hoofs as 500 piglets scramble away from Mike Male. “That's the sound of healthy ... Read More

Antibiotic resistance: The last resort

Health officials are watching in horror as bacteria become resistant to powerful carbapenem antibiotics — one of the last drugs on the shelf.

As a rule, high-ranking public-health officials try to avoid apocalyptic descriptors. So it was worrying to hear Thomas Frieden and Sally Davies warn o... Read More
