The people of Guinea have been locked in a life-and-death struggle with Ebola virus since last December. Nearly 60 percent of Guineans infected with the virus since then have died. To cope with the unprecedented disease, the government went so far as to ban soup made from bats.
Why bats? Bec... Read More
In light of the recent emergence of the lethal Ebola virus in the US, the National Science Foundation (NSF) is accepting proposals to conduct non-medical, non-clinical care research that can be used immediately to better understand how to model and understand the spread of Ebo... Read More
Two randomized trials in the October 8 issue of JAMA examine new vaccination strategies for the prevention and control of avian influenza, often referred to as “bird flu.” This is a theme issue on infectious disease.
In one study, Mark J. Mulligan, M.D., of the Emory University School of Medi... Read More
Multiple sclerosis (MS) is an electrical disorder, or rather one of impaired myelin, a fatty, insulating substance that better allows electric current to bolt down our neurons and release the neurotransmitters that help run our bodies and brains. Researchers have speculated for some time that th... Read More
A University of Otago researcher is part of an international team that has discovered that horizontal gene transfer (HGT) played a surprisingly large role in the evolution of primitive microbes known as archaea.
HGT, which involves acquiring genetic material from another unrelated organism in... Read More
Health authorities in Spain have confirmed that a health worker at the Carlos III Hospital in Madrid, Spain has been infected with the Ebola virus. This is the first time anyone has contracted the virus outside of Africa.
The woman, a nurse technician, had worked in the room where two Ebola p... Read More
The multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating brute force of traditional antibiotics, which wipe out everything at once, rega... Read More
If the past few years have taught us anything, it’s that our well-being is intimately linked to the health of animals.
The current Ebola epidemic probably got its start when someone came into contact with an infected animal, perhaps a monkey or a fruit bat. The virus causing Middle East respi... Read More
Conjugal plasmids provide microbes with full complements of new genes. Conjugal plasmid transfer is deemed responsible for the rapid spread of antibiotic resistance among microbes. While broad host range plasmids are known to confer transfer abilities to diverse hosts in pure culture, the extent... Read More

The great folks at "The People Behind the Science" interviewed me over Skype in late July, and the interview has just been released as a podcast. I discuss my path through science, my thoughts on teaching, research at undergraduate institution, and how to motivate and inspire students to strive... Read More
If you multiply the number of bacteria thought exist in one human being, say 1 x 1014 by how many humans there are, about 6.6 x 109, you get close to a familiar number.
And who was Avogadro anyway? Some eponyms fail to do justice to the eponymee. My favorite example is Amerigo Vespucci, whose... Read More
Plants that come under attack from pathogens have an automatic immune response. Fungi get around this plant immunity by injecting proteins into the host plant cells. These 'effector proteins' enable the fungi to escape the plant's immune system and allow the fungal cells to enter the plant unrec... Read More
Targets to eliminate tuberculosis by 2050 are more likely to be met if new vaccines are developed for adults and adolescents instead of for infants, according to new research.
Researchers at the London School of Hygiene & Tropical Medicine and the Stop TB Department at the World Health Organi... Read More
Tara Smith joins the TWiEBOVsters to discuss the Ebola virus outbreak in west Africa, spread of the disease to and within the US, transmission of the virus, and much more.
Salmonella bacteria are a common cause of infectious disease in human and animals. Salmonella is classically divided into species S. bongori and S. enterica – which is in turn further divided into more than 2,500 different serotypes. However, only a limited number of serovars that are responsibl... Read More
University of Leicester researchers unlock vital new information to improve vaccinations against pneumococcus infection.
Every ten seconds a human being dies from pneumococcus infection, making it the leading cause of serious illness across the globe. New research discovers six unique states ... Read More
Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants -- and first acted as energy parasites in those cells before becoming beneficial, according to a new study.

Many double-stranded DNA viruses infect cells by ejecting their genetic information into a host cell. But how does the usually rigid DNA packaged inside a virus' shell flow from the virus to the cell?
In two separate studies, Carnegie Mellon University biophysicist Alex Evilevitch has shown t... Read More
