When antibiotics first became available, farmers used them indiscriminately—dribbling streptomycin into chicken feed to boost growth and doling out low doses to fatten pigs. Now scientists know that the overuse of antibiotics in livestock can foster drug-resistant bacteria that are dangerous to ... Read More
A Yale University lab has crafted the first synthetic molecules that have both the targeting and response functions of antibodies.
The new molecules -- synthetic antibody mimics (SyAMs) -- attach themselves simultaneously to disease cells and disease-fighting cells. The result is a highly tar... Read More
Three-year outcomes from an ongoing clinical trial suggest that high-dose immunosuppressive therapy followed by transplantation of a person's own blood-forming stem cells may induce sustained remission in some people with relapsing-remitting multiple sclerosis (RRMS).

When a rapidly-growing cell divides into two smaller cells, what triggers the split? Is it the size the growing cell eventually reaches? Or is the real trigger the time period over which the cell keeps growing ever larger?
A novel study published online today in the journal Current Biology ha... Read More
We can’t see them, but they are all around us. On us. In us. Our personal microbes—not to mention those in the environment around us—have us outnumbered by orders of magnitude, but scientists are only beginning to understand how they influence our health and other aspects of our lives. It’s an i... Read More
Mice that are already infected with the pathogen that causes Lyme disease appear to facilitate the spread of a lesser-known but emerging disease, babesiosis, into new areas.
Research led by the Yale School of Public Health and published Dec. 29 in the journal PLOS ONEused laboratory experimen... Read More
Scientists from St. Jude Children’s Research Hospital and China Agricultural University identify the changes in H9N2 flu virus in chickens that could signal emergence of viruses with potential to trigger a pandemic.
An international research team has shown how changes in a flu virus that has ... Read More
The hollow Cola tree growing in a remote area of southeastern Guinea was once home to thousands of bats routinely hunted and killed by the neighborhood children. It was also a popular spot to play. A year ago, one child in particular lived within fifty meters of the tree: a two-year-old boy who ... Read More
A health worker who returned from West Africa and was found to have Ebola when she arrived home in Scotland was transferred on Tuesday to Britain’s designated treatment center for the disease in London.
The authorities also reported that two more people were being tested for the virus.

Since the first case, a two-year-old who passed away on 28 December 2013, there have been more than 6,900 deaths.
Outbreaks such as Ebola have an ability to spread fear around the world, often through the prism of sensationalist media reporting.
So how does Ebola actually compare to previo... Read More
A new study entitled “Microbiological diagnostic procedures for respiratory cystic fibrosis samples in Spain: towards standard of care practices” was published in BMC Microbiology by Juan de Dios Caballero and a group of researchers from Spain. In this study, the authors evaluated the compliance... Read More
A protein called GRP78 could be a universal therapeutic target for treating human diseases like brain cancer, Ebola, Influenza, Hepatitis and superbug bacteria such as MRSE and MRSA, according to a Virginia Commonwealth University-led pre-clinical study published this month in the Journal of Cel...

As 2014 comes to an end, let’s take a look at the year's biggest outbreaks, pathogens, and technofix dramas.
Ebola was arguably the biggest story of the year. Some of the best coverage, in my opinion, included this epic Washington Post story exploring why the outbreak grew so out of control; Ri... Read More
When Dr. Ian Crozier arrived in West Africa this past summer, he was stepping into the epicenter of the Ebola hot zone. The American doctor was working in the Ebola ward of a large, public hospital in Sierra Leone's dusty city of Kenema.
The trip nearly cost him his life. First came a fever, ... Read More
Whooping cough may be evolving to outsmart the currently used vaccine, say researchers.
Analysis of strains from 2012 shows the parts of the pertussis bacterium that the vaccine primes the immune system to recognise are changing.
It may have "serious consequences" in future outbreaks, UK r... Read More
A team of researchers led by Harvard geneticist George Church at the Wyss Institute for Biologically Inspired Engineering and Harvard Medical School (HMS) has made big strides toward a future in which the predominant chemical factories of the world are colonies of genetically engineered bacteria...

Two experimental DNA vaccines to prevent Ebola virus and the closely related Marburg virus are safe, and generated a similar immune response in healthy Ugandan adults as reported in healthy US adults earlier this year. The findings are from the first trial of filovirus vaccines in Africa. Read More
The room is framed by a small square of transparent plastic, clamped to each of my cheeks and secured with a strap around my forehead. My breathing, growing ever more laboured, sounds like an astronaut’s; the erratic inhale and exhale of someone short on oxygen and trying not to panic. A paper m... Read More
Vultures relish rotting meat but how do they survive the deadly bugs that infest their food? It seems they opt for the probiotic approach, enlisting good bacteria to ward off the bad, microbiologists at Aarhus University in Denmark discovered in a study published in Nature Communications.
