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 Terrance Williams was 21, he met a man in Syracuse, and the two became friends. Some weeks later, they became sexually involved. Williams and this partner—who, in court papers, is referred to only as “the victim”—used protection in their relationship, at first. But one night, Williams’s par... Read More
New research shows how disruption of human biological clock can have negative impact on human intestinal micobiome and in turn lead to metabolic dysfunctions such as weight gain and diabetes. Read More
As part of the Wellcome Trust Strategic Award for Medical Mycology and Fungal Immunology (WTSA MMFI), ten international students are awarded scholarships to complete a Masters of Research (MRes) at the University of Aberdeen, followed by a three-year PhD at any UK institution with expertise in t...

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...

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
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
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
A dangerous, often deadly, type of bacteria that lives in soil and water has been released from a high-security laboratory at the Tulane National Primate Research Center in Louisiana. Officials say there is no risk to the public. Yet despite weeks of investigation by multiple federal and state a... Read More
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
A Swiss teenager, recently returned home from a discotheque, came to the emergency department with classic sudden symptoms of stroke, only to be diagnosed with Lyme disease.
"Everything about her symptoms indicated stroke: speech deficits, poor comprehension and right-sided face and arm weak... 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...

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
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
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
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
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
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
