According to BBC News, the number of reported cases, as well as the number of fatalities linked w... Read More

When Parasites Catch Viruses

Researchers find a viral symbiont of a protozoan parasite increases virulence to the human host.

When humans have parasites, the organisms live in our bodies, co-opt our resources, and cause disease. However, it turns out that parasites themselves can have their own co-habitants.

The dual significance of bacterial protein secretion

Secretion of bacterial proteins is an essential biological process with biotechnological and biomedical impact on human health. European scientists studied a universal and widely conserved bacterial secretory pathway towards its utilisation in biotechnology and medicine.

The coordinated secr... Read More

Superman-strength bacteria produce gold

At a time when the value of gold has reached an all-time high, Michigan State University researchers have discovered a bacterium’s ability to withstand incredible amounts of toxicity is key to creating 24-karat gold.

“Microbial alchemy is what we’re doing – transforming gold from something th... Read More

Faster than a Speeding Bolt: Mycoplasma Walk This Way

Many prokaryotes move actively in liquid (swim) or on moist solid surfaces (swarm and glide) toward or away from a stimulus, such as a nutrient, light, or oxygen. Not surprisingly, prokaryotes have evolved numerous means of locomotion built around distinct molecular mechanisms.

How distinct? ... Read More

Human gut may engineer its bacterial environment via secretions

The human gut may help control the bacterial populations that live within it via secretions that kill some bacteria while supporting others, according to a study published Tuesday in the journal PLoS Biology.

The gut is an enormously complex environment inhabited not only by human cells but a... Read More

Bacterial 'FM radio' developed

Programming living cells offers the prospect of harnessing sophisticated biological machinery for transformative applications in energy, agriculture, water remediation and medicine. Inspired by engineering, researchers in the emerging field of synthetic biology have designed a tool box of small ... Read More

Man-made Bacteria Fights Man-Made Chemical Mess

Researchers have developed a bacteria strain that is uniquely effective at degrading the toxic industrial chemicals known as PCBs, or polychlorinated biphenyls.

PCBs are toxic man-made organic chemicals that pose a threat to human health and to the environment.

Gut bacteria may fight depression

Many people would be surprised to learn that bacterial cells in the digestive tract outnumber their own cells 10 to one.

Most don’t know that each person has a unique mix of gut bacteria, like a fingerprint.

And they certainly don’t know that giving this bacteria the royal treatment by eat... Read More

The Deadliest Virus

BIRD FLU (H5N1) has receded from international headlines for the moment, as few human cases of the deadly virus have been reported this year. But when Dutch researchers recently created an even more deadly strain of the virus in a laboratory for research purposes, they stirred grave concerns abo... Read More

Probiotics: A gut-check on bacterial health

A fascinating, if disconcerting, fact: More than 100 trillion so-called good bacteria thrive in or on the human body. A sizable chunk of them maintain residence in the human digestive tract. Probiotics, live microorganisms that benefit their human host, are among these beneficial bacteria.
