Two studies, in the journal Cell, found a mutation increased the virus' ability to infect human cells fourfold.
Scientists have argued the mutation may have been "pivotal" in the outbreak becoming the largest in recorded history.
There were 28,616 Ebola cases in Guinea, Liberia and Sierra ... Read More
Recent advances in imaging technology have provided unprecedented views of biological events as they unfold in living organisms. Researchers routinely create movies of processes such as cells dividing and differentiating into the neurons, muscle, and skin in a Petri dish or in tiny embryos, such... Read More
Parasitic flatworms known as schistosomes require a gene called cpb1 in order to survive in mice, according to a new study published in PLOS Pathogens. The study also shows that schistosome stem cells grow in response to injury.
Schistosomes afflict more than 200 million people worldwide and ... Read More
Researchers at Oregon State University have identified for the first time another bacterium that can cause symptoms similar to "salmon poisoning" in dogs - and may complicate the efforts of Pacific Northwest pet owners to keep their dogs protected and healthy.
The Pacific Northwest, from nort... Read More
The TWiM team brings you a bacterium from a Colorado field site that grows on uranium, and copper resistance in the emerging pathogen Acinetobacter baumannii.
Most of the research to understand the effects of Zika infections has focused on pregnant women and birth defects. But new study in mice that focuses on the male reproductive system raises serious concerns about its effects on men.
Three weeks after male mice were infected with Zika, their te... Read More
Donald Trump has a long history of promulgating anti-vaccine conspiracy theories (contrary to received wisdom, the anti-vaxx movement draws most of its support from the political right, not liberals), and the tireless leaders of the anti-vaccine movement now claim to have met with Trump and rece...

All around you, life exists in microscopic communities — carpeting the insides (and outsides) of humans and animals, oceans, atmospheres, and ecosystems in between. Researchers have learned these microbes are ubiquitous and central to the makeup of most life on earth. But what scientists are sti... Read More

Polysorbate, a safe additive found in everything from ice cream to cosmetics, has been proven to slow the toxic effects of E. coli poisoning.
Had this discovery been known before the deadly 2011 E. coli outbreak in Germany, doctors may have had one more tool to save some of victims.
The fi... Read More
Implanted medical devices such as left ventricular-assist devices for patients with heart failure or other support systems for patients with respiratory, liver or other end organ disease save lives every day. However, bacteria that form infectious biofilms on those devices, called device-associa... Read More
Shafiqul Islam, Sc.D., of Tufts University School of Engineering, has been awarded the 7th Prince Sultan Bin Abdulaziz International Prize for Water (PSIPW) Creativity Award, one of most prestigious international awards focusing on water-related scientific innovation. Islam was recognized for hi... Read More
The delay between the time when a disease outbreak becomes possible and when it actually happens depends chiefly on how frequently infection is introduced to the population and how quickly the number of cases caused by a single individual increases, according to new research from the University ...

Infection control is a vital part of maintaining a safe healthcare facility, and the use of biocides and disinfectants to eliminate potential pathogens is an important part of infection control strategy. Pathogens can spread among patients via transfer to surfaces like doors, floors, and counter... Read More
A turfgrass disease that looked like an ink spill on many southern golf courses has been identified and all but blotted out, according to a plant pathologist with the Texas A&M AgriLife Extension Service.

he Zika virus attacks cells in mouse testes crucial for sperm and sex hormone generation and hampers reproduction, according to new research that raises the possibility that the virus could affect fertility in men.
And even if the same outcomes bear out in people, researchers have no idea wha... Read More
Klebsiella pneumoniae bacteria exposed to chlorhexidine-containing disinfectants can become resistant to colistin, a last resort antibiotic often used against multidrug resistant pathogens. This is the first study to link exposure to chlorhexidine with resistance to colistin in this clinically i... Read More
