Hello TWiM team,
The drought that has the entire country in its grip is affecting more than the color of people’s lawns. It may also be responsible for the proliferation of a heat-loving amoeba commonly found in warm freshwater bodies, such as lakes, rivers and hot springs, which the drought has made warmer than...

The Human Microbiome Project (HMP) is a global initiative to identify and characterize the microorganisms present at multiple sites in the human body. An international team of researchers reports on new ways to harness the results of the HMP and discusses how changes in the microbiome might affe... Read More
A report in Biology Letters shows that the drool of herbivores might help defeat the toxic fungal defences of the plants they graze on.
Grazing or cutting some plants induces a noxious chemical to be produced which deters hungry plant-eaters from revisiting them. The chemicals, called alkaloi... Read More
Using a new technique to track the swimming motion of a single bacterium, researchers have discovered that the movement of the bacterium’s body — not just thrust from the flagellum — allow movement through fluids. The finding could shed new light on the evolution of cell body shape.

Aaron Wheeler is the director of an interdisciplinary research group at the University of Toronto in Canada. The group develop lab-on-a-chip techniques for applications in biology, chemistry and medicine.
You recently reported an exciting technique that can screen algae grown under different ... Read More
Microbiota buffs repeat it often these days, proudly reminding the public that the microbial cells associated with humans outnumber their host cells by a ratio of ten-to-one. In his letter in the February 2014 Microbe, however, Judah L. Rosner of the National Institutes of Health (NIH) makes a s... Read More
A positive D test indicates that the presence of macrolide-inducible resistance to clindamycin produced by an inducible methylase enzyme that alters the common ribosomal binding site for macrolides, clindamycin and the group B streptogrammins (quinupristin). This cross-resistance, called the ML... Read More
A new combination drug therapy cures chronic hepatitis C in most patients also infected with HIV—and without the side effects of current treatments.
The advance is important, researchers say, because about a third of HIV patients in the United States also have hepatitis C. There are an estima... Read More
A UAB research concludes that the Streptococcus mutans, one of the principal bacteria causing dental caries, has increased the changes in its genetic material over time, possibly coinciding with dietary changes linked to the expansion of humanity.

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
Cancer has left its 'footprint' on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.
Viral relics are evidence of the ancient battles our genes have fought against infection. Occasionally the retroviruses th... Read More
A probiotic that prevents obesity could be on the horizon.
Bacteria that produce a therapeutic compound in the gut inhibit weight gain, insulin resistance and other adverse effects of a high-fat diet in mice, Vanderbilt University investigators have discovered.
“Of course it’s hard to spec... Read More
The Human Microbiome Project revealed tens of trillions of microbes residing in and on humans. Now scientists are taking a census of plant microbes—and not just the hundreds of billions found in soils. Distinct microbial communities live inside roots, on leaves and within flowers, and all in all... Read More
The technique addresses the problem of hidden reservoirs of HIV in the body, and could herald a new way of battling the viral infection.
Once HIV invades the body, it doesn’t want to leave. Every strategy that scientists have developed or are developing so far to fight the virus – from powerf... Read More
The joys of anaerobic digestion
One U.K. grocery store plans to power itself using biogas harvested from its own unsold, rotting produce. Yum.
A Sainsbury's store in Cannock in central England is getting access to anaerobic digesters. The store plans to use electricity solely from the dige... Read More
Accelerated progress against the global burden of HIV, malaria, and tuberculosis (TB) has been made since 2000 when governments worldwide adopted Millennium Development Goal 6 to combat HIV/AIDS, malaria, and TB. New estimates from a major new analysis show that worldwide, the number of people l... Read More
A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-... Read More
Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution.
