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. T... Read More
Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.
MERS, a serious respiratory illness caused by a virus known as a coronaviru... Read More
