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
DURHAM, NC - Within each strand of DNA lies the blueprint for building an organism, along with the keys to its evolution and survival. These genetic instructions can give valuable insight into why pathogens like Cryptococcus neoformans -- a fungus responsible for a million cases of pneumonia and... Read More
Drawing from his engineering background, Princeton University researcher Alexandre Persat had a notion as to why the bacteria Caulobacter crescentus are curved — a hunch that now could lead to a new way of studying the evolution of bacteria, according to research published in the journal Nature ...

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
A second American aid worker in Liberia has tested positive for Ebola, according to the Christian humanitarian group she works for.
Nancy Writebol is employed by Serving in Mission, or SIM, in Liberia and was helping the joint SIM/Samaritan's Purse team that is treating Ebola patients in Monr... Read More
A cold breeze blew off the Antarctic plain, numbing the noses and ears of scientists standing around a dark hole in the ice. Flecks of ice crackled off a winch as it reeled the last few meters of cable out of the hole. Two workers in sterile suits leaned over to grab the payload — a cylinder the... Read More
Hi TWIM, TWIV and TWIP Argonauts,
Your three wonderful podcasts are the nutrient media for growing my scientific knowledge. I have been downloading them from ITunes for a couple of years, and although as a mere amateur I sometimes struggle to keep ... Read More
Scientists have identified peptides from parasitic hookworms that can calm the body’s immune response and perhaps pave the way to treat autoimmune diseases.
Experts believe the peptide molecules could help explain why worm infections can effectively treat diseases such as multiple sclerosis, ... Read More
Investigators at the University of Southampton have discovered that two new vaccines can prevent the transmission of meningitis bacteria from person to person.
The vaccines do this by reducing ‘carriage’ of the responsible bacteria in the nose and throats of the population.
Meningitis is... Read More
As more and more information becomes available, one marvels (and also frets) at the sophisticated strategies that pathogens have evolved in order to evade their hosts’ defense mechanisms. Many pathogens of plants and animals deliver effectors into their hosts in order to suppress immune response... Read More
“She did pioneering work in genetics, but it was her husband who won a Nobel price.” So said an obituary in the British newspaper The Guardian regarding Esther Lederberg, a North American microbiologist married to Joshua Lederberg from 1946 to 1966 . Being married to and working along such a... Read More
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
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

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
Enhancing the discoverability of public health and epidemiology research data is a key to ensuring that it gets more widely used. This was the topic of a recent workshop hosted by the London School of Hygiene and Tropical Medicine, where researchers and data experts explored the findings of a re... 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
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
