Among gut microbes, strains, not just species, matter

A large community of microorganisms calls the human digestive tract home. This dynamic conglomerate of microscopic life forms - the gut microbiome - is vital to how people metabolize various nutrients in their food, how their immune systems react to infection, and how they respond to various med...

Scientists Hit Antibiotic Pay Dirt Growing Finicky Bacteria In Lab

Scientists say they have discovered a natural compound from bacteria that may prove to be a potent new antibiotic. This news comes at a time when many current antibiotics are losing their oomph — germs become resistant to them.

The new compound is especially intriguing because it appears that... Read More

Land of the bacteria-eaters

For hospital workers an outbreak of harmful bacteria in the wards is a nightmare, but what gives bacteria nightmares?

Perhaps the prospect of being eaten alive by a kind of viral parasite called a bacteriophage (bacteria eater): unlike antibiotics, which some bacteria have evolved a resistanc... Read More

Viruses take down massive algal blooms, with big implications for climate

Humans are increasingly dependent on algae to suck up climate-warming carbon dioxide from the atmosphere and sink it to the bottom of the ocean. Now, by using a combination of satellite imagery and laboratory experiments, researchers have evidence showing that viruses infecting those algae are d... Read More

Yeast Coaxed To Make Morphine

Genetically manipulated yeast can produce morphine, which could help get around the problems with poppy crops, which include climate, disease and war. Karen Hopkin reports.

Yeast. They already participate in producing some of the most popular pain-killing substances around: beer and wine. Now... Read More

THESE MICROBES ‘EAT’ ELECTRONS TO MAKE METHANE

In a new study, researchers demonstrate for the first time how methanogens obtain electrons from solid surfaces. The discovery could help scientists design electrodes for microbial “factories” that produce methane gas and other compounds sustainably. Read More

How bacteria control their size

Scientists have traditionally studied bacteria in large numbers, not individually. Working with tens of millions of cells in a culture flask, they tracked their growth by looking at how much the cells dimmed light passing through a tube.

Using this method, scientists learned that populations ... Read More

A virus that melts sea stars

Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More

Microbiology: Microbiome science needs a healthy dose of scepticism

Explorations of how the microscopic communities that inhabit the human body might contribute to health or disease have moved from obscure to ubiquitous. Over the past five years, studies have linked our microbial settlers to conditions as diverse as autism, cancer and diabetes.
