The ancestors of a large family of parasites—including those that cause malaria—were equipped to become parasites much earlier in their lineage than previously assumed, according to University of British Columbia (UBC) research.
The work, published in PNAS, traces the emergence of parasitism ... 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
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...

An experimental compound empowers an enzyme to help process acetaldehyde, a toxic metabolite of alcohol, according to new research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The findings, now online in the Proceedings of the National Academy of Sciences (PNAS), ... Read More

Caring for People Infected with Ebola: Stories from the Frontlines
Narrative Inquiry in Bioethics will publish a collection of personal stories from individuals who have been at the frontlines of healthcare for Ebola patients—whether as healthcare workers, family caregivers,... Read More
A mysterious illness that seems to have killed a farmer in Kansas has led to the discovery of a new virus last week: the Bourbon virus.
The farmer had been working on his field last spring when he got several tick bites, including one that appeared to be attached to his shoulder. A few days l... Read More
Salt and acid-tolerant bacteria with the potential to be used in mining processing have been uncovered in the Wheatbelt.
The bugs were found during a "bio-prospecting" survey near Merredin and are likely to become more important in WA in coming decades as high-grade ore runs out.
CSIRO envir... Read More
While an Ebola epidemic has been raging in West Africa since March 2014, an outbreak of this haemorrhagic fever occurred in the Democratic Republic of the Congo (DRC) in August, leaving fears over the virus' spread to Central Africa. A study by the IRD, the Institut Pasteur, the CNRS, the CIRMF... Read More
How frequently do microbes exchange genes when living on a host? This question has been on my mind lately. Broadly speaking, the discovery of horizontal gene transfer (HGT) revolutionized the way we think about prokaryotic evolution. No more could we think only of inheritance via vertical descen...

Multiple governments and non-governmental organizations have called on health-care personnel the world over to help control West Africa's Ebola outbreak; these include Médecins Sans Frontières (MSF), the World Health Organization (WHO) and United Nations children's charity UNICEF. But the demand... Read More
Microbes: They're everywhere, including inside our bodies. But are they really necessary? Not to life, scientists argue in a new paper — but certainly to life as we know it.
For starters, microbiologists Jack Gilbert and Josh Neufeld had to put aside the internal cell structures that were pro... Read More
Bacteria that can swim propel themselves with corkscrew tails anchored in rotary motors. That may seem surprisingly mechanical for a microbe, but it is a system that has been wildly popular and conserved across billions of years of evolution.
To see what I mean, I encourage you to visit this ... Read More
Mycorrhizal fungi live in the roots of host plants, where they exchange sugars that plants produce by photosynthesis for mineral nutrients that fungi absorb from the soil. They include some of the most conspicuous forest mushrooms, including the iconic, flaming red “fly agaric,” Amanita muscaria... Read More
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
A new study by a team of researchers that includes University of Notre Dame scientists Joshua Shrout and Mark Alber provides new insights into the behavior of an important bacterial pathogen.
Alber, Vincent J. Duncan Family Professor of Applied Mathematics, and Schrout, an associate professor... Read More
Engaging in unprotected sex with multiple partners increases the risk of contracting multiple strains of HIV, the virus that causes AIDS. Once inside a host, these strains can recombine into a new variant of the virus. One such recombinant variant observed in patients in Cuba appears to be much ... Read More
You must have heard it said that no one is indispensable to an institution. Maybe so, but such truths come in degrees. Every so often someone comes along who makes a genuine difference in how an organization functions. I turn here to Michael Goldberg, who thirty years ago began a most distinguis... Read More
Dear water-based life forms:
It is 24 degrees in Overland Park, Kansas and I am looking at a slide labeled "Giardia lamblia", part of a museum exhibit on water and human (over) use of water.
I see a greenish lump. I don't kno... Read More
The human body doesn’t like outsiders. When a foreign pathogen or substance, say an unwanted virus, finds its way into our blood streams we produce antibodies that the neutralize the threat. These “Y”-shaped proteins are made by a class of white blood cells called plasma cells and bind to molecu... Read More
