Since the introduction of highly active antiretroviral therapy in the mid-1990s, HIV infection has evolved from a near-certain death sentence to a manageable, chronic disease. Still, ... 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
Entamoeba, an amoeba that includes pathogens of the intestinal tracts of a range of hosts - humans are included. They have no mitochondria and seem to have adapted secondarily to an anoxic way of life. Cytoplasm of a thick and dense consistency, and like that of pelobionts (to which we think the... Read More
This episode: Engineered bacteria can be made to produce many different useful kinds of biofilm!
(10.5 MB, 11.5 minutes)
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
Nearly 40 years ago, a young Belgian scientist travelled to a remote part of the Congolese rainforest - his task was to help find out why so many people were dying from an unknown and terrifying disease.
In September 1976, a package containing a shiny, blue thermos flask arrived at the Instit... Read More
Converting plant biomass into useful products and biofuels inevitably runs up against a big problem: degrading cellulose and other cell wall polymers, which are, by design, tough nuts to crack. Plants need tough cell walls in order to stand tall and compete for sunlight, but the recalcitrance of... Read More
Europe set out plans to boost research into the neglected area of antibiotics on Thursday by promising to accelerate approval of new drugs, while ensuring adequate prices for their makers and promoting industry-wide R&D.
Multi-drug resistant bacteria, or so-called superbugs, are a growing thr... Read More
We know that life on earth is incredibly diverse. It can survive deep in the trenches of the ocean and in the frozen permafrost of the arctic. Surely we have much to learn from the study of life, but we also have much to learn about the virus. Even though they are not considered living things, t... 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
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
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
Considered as an obsolete theory for many years, the transmission of acquired traits has returned to the forefront of debate thanks to the development of epigenetic research. In this context, a team of researchers has described how in Paramecia, mating types are transmitted from generation to ge... Read More
Russian engineers are scrambling to save the Phobos-Grunt spacecraft amid ever-bleaker signs the mission may be lost. The probe was launched uneventfully Nov. 8, but soon afterward its thruster failed to fire to send it on a course toward Mars, leaving the spacecraft stranded in Earth orbit.

New estimates indicate that over 650,000 children develop tuberculosis (TB) every year in the 22 countries with a high burden of the disease -- almost 25 percent higher than the total number of new cases worldwide estimated by WHO in 2012. The research also suggests that about 15 million childre... Read More
Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some members of the fungi, algae, and animals such as rotifers. Many macro animals and plants have juvenile stages which are also microorganisms. Some microbiologists also clas... Read More
Scientists from the University of Granada have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach cancer. These important findings constitute the first use of a food as a natural drug an... Read More
Nearly two years after the Deepwater Horizon disaster gushed millions of barrels of oil into the Gulf of Mexico, tar balls from the spill still turn up on Alabama's shores after storms. Now, one researcher is recommending that people steer clear of these tar balls after studies find them chock-f... 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
