This episode: Some insects have bacterial symbionts with super-small genomes inside their cells, and some of these symbionts have their own internal bacterial symbionts!
A new coronavirus, similar in nature to SARS (Severe Acute Respiratory Syndrome), has infected six and resulted in two deaths in the Middle East, various media outlets have reported this weekend.
According to BBC News, the number of reported cases, as well as the number of fatalities linked w... Read More
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.

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
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
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

Physicians should pay attention to their "gut feeling" that something may be seriously wrong when assessing a child with an infectious disease -- even if the clinical appearance is reassuring -- an observational study suggested.
Among 3,369 children whose primary care evaluation did not sugge... Read More
Vincent, Alan, Rich and Kathy discuss the association of a virus with sea star melting disease, and the finding of a phycodnavirus in the oropharynx of humans with altered cognitive functions.
The UK’s first laboratory confirmed case of Crimean Congo Viral Hemorrhagic Fever (CCVHF) has died. Even so, health officials are stressing that this will not become a public outbreak. The Health Protection Agency is adamant the 38-year-old unnamed man poses no threat to others.
“It can be ac... Read More
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
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
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.
The Environmental Protection... Read More
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
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
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.
Pr... Read More

And they said meth never did a body good.
A study conducted by researchers in Taiwan found that methamphetamine may possess flu-fighting properties, Medical Daily reported.
The study, published Tuesday in PLoS One, exposed human lung cells to varying quantities meth, then infected them wit... Read More
