Link between small mammals and evolution of hepatitis A virus to humans discovered

Researchers at the University of North Carolina at Chapel Hill (UNC-Chapel Hill) are part of an international team led by the University of Bonn, Germany, who have found a link between the origin of hepatitis A virus (HAV) and small mammals. With the emergence of Ebola virus from bats and hantav... Read More

Microbiomes could hold keys to improving life as we know it

A consortium of 48 scientists from 50 institutions in the United States - including Pamela Silver, Ph.D., a Core Faculty member at the Wyss Institute for Biologically Inspired Engineering at Harvard University - are calling for a Unified Microbiome Initiative that would span national cross-insti...

What effect does environmental temperature have on bacterial virulence?

A recent tragic die-off of saiga antelope has scientists puzzled about what could cause such a sudden, drastic, large-scale death. Infectious disease could easily be playing a part, with Pasteurella multocida and Clostridium perfringens both possible candidates found in animal necropsies. The su... Read More

Diagram captures microbes’ influence across animal kingdom

One finding from a study published September 15 in Scientific Data that matched animals with their known microbes and drew connections between species with similar microbial crews found at least 233 species of bacteria, viruses and more live on or inside both humans and dogs. The diagram publish... Read More

MGH team broadens utility of more compact CRISPR-Cas9 by increasing its targeting range

A team of Massachusetts General Hospital (MGH) investigators has shown that a method they developed to improve the usefulness and precision of the most common form of the gene-editing tools CRISPR-Cas9 RNA-guided nucleases can be applied to Cas9 enzymes from other bacterial sources. In a paper r... Read More

Early hospitalization key to survival for Ebola victims

A retrospective study of Ebola epidemics in the Democratic Republic of Congo (DRC) suggested that each day of delay in hospital admittance was associated with an 11% increased risk of death for Ebola patients during epidemics. Read More

Yet another reason to avoid methamphetamine: negative effects of meth on wound healing

Tug of war among bacteria

At the University of Cologne, biophysicists in the lab of Professor Berenike Maier were now able to show how differential mechanical forces can lead to cell sorting in biofilms, thereby determining their architecture. In their publication in the journal eLife, the team headed by the biophysicist... Read More

Could self-disseminating vaccines cut off emerging infectious diseases at source?

The 2014/2015 Ebola outbreak in West Africa shone the spotlight not only on the unpreparedness of local health services and science to deal with the pandemic, but also on the phenomenon of emerging infectious diseases (EIDs). Read More

New Technique Could Prevent Biofilms on Catheters and Medical Implants

Washington, DC – October 30, 2015 – Biofilms—mats of bacteria similar to the plaque that grows on teeth—frequently coat the surfaces of catheters, and of various medical implants and prostheses, where they can threaten lives or lead to failure of the implants. Antibiotics are impotent against b... Read More

'Ensemble' modeling could lead to better flu forecasts, study finds
