"When people think about food-borne pathogens, normally they list bacteria, viruses, and maybe parasites. Fungal pathogen... Read More

Bacterial switches in the human gut pave way for therapeutic manipulation

The microbial ecosystem in the human gut can switch from one stable state into another, without staying for a long time in between. Key groups of bacteria tend to be either nearly absent, or relatively abundant in any given individual. This discovery highlights fundamental organizing principles ... Read More

Mollusk parasite culturing methods drive research

Researchers at Bigelow Laboratory for Ocean Sciences dug into the last 70 years of peer-reviewed publications about protozoan parasites that infest bivalve mollusks and found that when an organism can be cultured in the laboratory, more papers and greater understanding result. Senior Research S... Read More

Ebola outbreak: 25 more deaths confirmed in West Africa

The research also suggests that about 15 million childre... Read More

Smallpox Virus Found In Unsecured NIH Lab

Scientists cleaning out an old laboratory on the National Institutes of Health campus in Bethesda, Md., last week came across a startling discovery: vials labeled "variola" — in other words, smallpox.

Under international convention, there are supposed to be only two stashes of this deadly vir... Read More

How to Employ a Microbe?

For many people microbes are associated with infections, diseases and in general mainly negative things but some microbes actually do more good than bad for us. We often take for granted that without microbes we would not have many things that we eat and use everyday and, as a matter of fact, hu... Read More

Ocean microbes display a hidden talent: releasing countless tiny lipid-filled sacs

In the search for a renewable energy source, systems using algae look like a good bet. Algae can grow quickly and in high concentrations in areas unsuitable for agriculture; and as they grow, they accumulate large quantities of lipids, carbon-containing molecules that can be extracted and conver...

Calcium makes for an environmentally friendly pickle

George Washington had a collection of 476 kinds of pickles. To prevent scurvy, Christopher Columbus stocked pickles on the Niña, Pinta, and Santa Maria. Julius Caesar, believing pickles to be invigorating, added them to the Roman legions' diet. In 5000 BCE, the Babylonians were known for picklin... Read More

COULD MAGNETIC BACTERIA BE THE NEXT GENERATION OF MICROBOTS?

The cutting edge of robotics may not be a smarter Siri or a less-creepy humanoid Japanese robot. It might be a swarm of bacteria, compelled to do our bidding through a remotely controlled magnetic field.

Some of the biggest technological advances of the past two decades have involved scaling ... Read More
