Microbe Responsible for Methane from Landfills Identified

Researchers have long known that landfills produce methane, but had a hard time figuring out why -- since landfills do not start out as a friendly environment for the organisms that produce methane. New research from North Carolina State University shows that one species of microbe is paving the... Read More

Common bacteria at root of Adler's sudden passing

If there is one thing Dr. P.J. Brennan wants his medical students to take away from his class, it's a healthy respect for Staphylococcus aureus, a common strain of bacteria found on skin and in the nose.

It can cause a range of infections, from pimples to endocarditis. The latter is the same ... Read More

Cell Culture in Three-dimensional Environments

At Karlsruhe Institute of Technology (KIT), researchers of the DFG Center for Functional Nanostructures (CFN) succeeded in specifically cultivating cells on three-dimensional structures. The fascinating thing is that the cells are offered small "holds" in the micrometer range on the scaffold, to... Read More

Protein reveals HIV vaccine targets

A component of a potential vaccine opens to rearrange proteins and to possibly reveal new targets to prevent HIV infection and AIDS. An international team of researchers from the U.S., Sweden, and France studied the structure and behavior of the HIV envelope protein complex, which could serve as... Read More

Do you trust the five-second rule? If so, read this.

Residence time and food contact time effects on transfer of Salmonella Typhimurium from tile, wood and carpet: testing the five-second rule. Salmonella Typhimurium can survive for up to 4 weeks on dry surfaces in high-enough populations to be transferred to foods and S. Typhimurium can be transf... Read More

Migratory Birds, Domestic Poultry and Avian Influenza

The persistence and recurrence of H5N1 avian influenza in endemic regions can largely be blamed on movement and infection by migratory birds. Trade in poultry, poultry products and caged birds, and movement of wild birds also account for H5N1 prevalence in these areas. Several recent outbreaks o... Read More

Science 101: Different Teaching Fosters Better Comprehension, Study Finds

Introductory science courses - in biology, chemistry, math and physics - can be challenging for first-year college, CEGEP and university students. Science 101 courses can make or break a student's decision to venture into a scientific field or even pursue higher education.

"The language, fund... Read More

NEJM video on hand washing in clinical care

The ASM has for a number of years been supporting a hand washing campaign. The 31 March 2011 issue of The New England Journal of Medicine has a very good 14-minute-long video on hand washing in clinical care. (Pre-surgical hand scrubbing is not covered.) The video is by Yves Longtin, Hugo Sax, B... Read More

New research venture between Liverpool and Saudi Arabia aims to advance global response to infectious diseases

The Kingdom of Saudi Arabia's Ministry of Health (KSA MoH), the Liverpool School of Tropical Medicine (LSTM) and the Innovative Vector Control Consortium (IVCC) have launched a new venture to significantly increase the global ability to control major infectious diseases such as malaria and dengu...

Feds Want Meat To Pass Contamination Tests Before Shipping

Would it surprise you to learn that meat can be shipped out to stores before processors know whether it's contaminated with bacteria?

Well, that has been the case. And it's a problem. Foodborne illnesses make 48 million people sick every year, according to the government.

Processors have b... Read More

Pneumococcus: Nature’s Tiniest Cheat

To a pathogenic microbe, the human body is a foreboding environment filled with bacteriocidal immune cells ready to seek out and destroy foreign invaders. When a leukocyte detects the presence of pathogen-associated molecular patterns (PAMPs) present on the surface of pathogenic bacteria, it rel... Read More

Wanted: Adventurous microbes for mission to Mars (video)

Scientists seek reliable, self-sufficient bacteria and algae to provide astronauts with oxygen and food on two-year round-trip to Mars.

Ability to recycle human waste desirable.

Researchers Link Herpes To Alzheimer's Disease

Laboratories at the University of New Mexico (UNM), Brown University, and House Ear Institute (HEI) have developed a new technique to observe herpes simplex virus type 1 (HSV1) infections growing inside cells. HSV1, the cause of the common cold sore, persists in a latent form inside nerve cells.... Read More

Treating Wounds With a Rubber Stamp?

Using an advanced form of a rubber stamp, researchers have developed a way to adhere an ultra-thin antibacterial coating to a wound.

The active ingredient, silver, "has been used to prevent and treat infections for ages," says first author Ankit Agarwal, a postdoctoral fellow in chemical and... Read More

Two new studies seek to validate the results of retracted 2004 paperon parasite-to-host gene transfer

The microparasite that causes Chagas disease really can integrate bits of its genetic material into its host's genome, where it can then be inherited by the host's offspring, according to two studies published in PLoS ONE and PLoS Neglected Tropical Diseases (PLoS NTD). Read More

Genetically Modified Cows Produce Milk Akin To Human Milk

In a potential new step for genetically modified food, babies could someday drink human-like milk derived from herds of genetically modified dairy cows, which scientists say could supplement breast milk and replace baby formula.

Scientists have created 300 cows that produce milk with some of ... Read More

Chilean Antarctic survey finds dramatic variety of organisms adapted to unusual conditions.

You might not expect bacteria living in Antarctic ice to be well suited to life in a boiling kettle, but that is what Chilean scientists discovered during an expedition last year. The researchers have turned up more than 200 new species of microorganisms adapted to living in extreme environments... Read More

Salamander Has Algae Living Inside Its Cells

In a symbiotic union more complete than any previously found in vertebrates, the common spotted salamander lives with algae inside its cells.

Such a degree of cross-species fusion was long thought to exist only among invertebrates, whose immune systems are not primed to destroy invaders. But ... Read More
