Modified E. coli spin fibres as tough as spider silk

Spider silk is stronger than steel and tougher than Kevlar, but efforts to spin our own have so far failed to match the real thing. Now a German research group has come up with artificial fibres that equal its toughness, which could lead to safer airbags.

His team spliced spider genes into E.... Read More

Bacteria ‘factories’ churn out valuable chemicals

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...

Developing global expertise in medical mycology and fungal immunology

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...

Fungi

In a Microbiology Lab,we are always delighted to find something new.Specially when their is contaminant on the media which is kept for discarding.Microbiology is a subject in which you are never at rest. Read More

Of Planes, Microbes and Clocks

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

Michael Goldberg, Thirty Years The ASM's Executive Director

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

Retracing the Roots of Fungal Symbioses

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

Ebola Survivor: The Best Word For The Virus Is 'Aggression'

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

Infectious disease: Mobilizing Ebola survivors to curb the epidemic

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

Life would go on if all bacteria disappeared

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

Ebola in DRC: a new strain of the virus

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

"Bioleaching" bugs present viable mining method

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

Life on a Pig's Skin

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...

Bacterial Motors Come in a Dizzying Array of Models

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

Q&A: Seth Mnookin on vaccination and public health

Seth Mnookin, an assistant professor of science writing and associate director of MIT's Graduate Program in Science Writing, is the author of "The Panic Virus: The True Story Behind the Vaccine-Autism Controversy", an acclaimed book that examines how inaccurate scientific reports linking vaccine...

New study offers novel insights into pathogen behavior

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

A Pill That Mimics the Immune System

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

Trial confirms Ebola vaccine candidate safe, equally immunogenic in Africa

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

Colonies of candida species:

Rousselle et al (2) incorporation of chromogenic or fluorogenic hexosaminidase substrates ... Read More

Sizing up cells: Study finds possible regulator of growth

Modern biology has attained deep knowledge of how cells work, but the mechanisms by which cellular structures assemble and grow to the right size largely remain a mystery. Now, researchers may have found the key in a dynamic agglomeration of molecules inside cells.
