New Species of Bacterium Found in Swedish Fjord

Researchers at the Sven Lovén Centre for Marine Sciences at the University of Gothenburg have discovered a brand new species of bacterium found only in the Gullmarsfjord north of Gothenburg. The bacterium has been named Endoxenoturbella lovénii to honour the newly founded marine research center.... Read More

Counting sea life, sometimes little things are big

If the Census Bureau thinks it has its hands full counting Americans, imagine what scientists are up against in trying to tally every living thing in the ocean, including microbes so small they seem invisible.

And just try to get them to mail back a form.

The worldwide Census of Marine L... Read More

The Basics: How Phenol Extraction Works

Phenol extraction is a commonly used method for removing proteins from a DNA sample, e.g. to remove proteins from cell lysate during genomic DNA preparation. It’s commonly used, but not commonly understood.

This article describes the basic protocol and explains solvents in detail before an ex... Read More

Important Considerations for Determining qPCR Efficiency

One of the very first things you need to do when getting set up for quantitative PCR (qPCR) is to determine the efficiency of the assay because knowing the assay efficiency is critical to accurate data interpretation. And you have to do this every time you design and purchase a new primer pair.

DO’s and DON’Ts for Isolation of DNA and RNA from Biofilm

In a previous article, we discussed the basic characteristics of biofilm samples and factors that influence sample prep and handling. Today we want to share with you some very important tips for isolation of DNA or RNA from biofilm samples. After working with numerous different biofilms and bio... Read More

Inhibition of XMRV by a weapon of mass deamination

All mammalian genomes contain genes encoding Apobec proteins. Several members of this protein family (the name stands for apolipoprotein B mRNA editing complex) are induced by interferon and are intrinsic antiretroviral proteins. Apobec proteins inhibit the replication of XMRV, a new human retro... Read More

Mouthwash recalled on bacteria fears

Health Canada is recalling a mouthwash sold at Dollarama stories across Canada after testing showed it includes a dangerous bacteria.

Pseudomonas fluorescens may cause abscesses in open wounds, and could have more serious complications in people with weakened immune systems.

You can learn a lot from a little pandemic

The doctor who would become the Canadian face of pandemic prevention was struggling to appear calm while under attack at a parliamentary subcommittee one year ago this week.

Chief public health officer David Butler-Jones was being grilled by MPs over the agency's handling of the listeriosis f... Read More

U.S. Navy Targets Microbe that Feasts on Mud for New Fuel Cell

“Think of it as a battery that runs on mud,” says the U.S. Office of Naval Research, and there in a nutshell is the concept behind the Navy’s new microbial fuel cell. The Navy has been using small lightweight microbial fuel cells to power sensors (to track sea turtles, for example) and now its g... Read More

New species of human malaria recognized

Scientists investigating ovale malaria, a form of the disease thought to be caused by a single species of parasite, have confirmed that the parasite is actually two similar but distinct species which do not reproduce with each other, according to research published in The Journal of Infectious D...

Autumn Leaves

Each autumn, as the leaves on the apple trees in the Loire Valley turn from green to gold, observant orchardists notice islands of healthy green within the otherwise yellow leaves. These islands coincide with the site of leaf mines created by the larvae of a small moth, the apple leafminer Phyl... Read More

Kenya: Pig Farmers Are Focus of Effort to Stop Spread of Parasite That Causes Epilepsy

Researchers in Kenya have been trying a seemingly unlikely tactic to prevent epilepsy: teaching farmers to tether their pigs.

The goal is to stop the pigs from spreading a type of tapeworm that can infect the brain in humans and that is a major cause of epilepsy in poor countries, particularl... Read More

Asking 'What would nature do?' leads to a way to break down a greenhouse gas

A recent discovery in understanding how to chemically break down the greenhouse gas carbon dioxide into a useful form opens the doors for scientists to wonder what organism is out there—or could be created—to accomplish the task.

University of Michigan biological chemist Steve Ragsdale, along... Read More

Biotech Revolution (BBC Four)

Theoretical physicist and futurist Michio Kaku looks at the revolution in genetics and biotechnology, which promises unprecedented health and longevity but also raises fears of a future where we can genetically engineer people. The documwentary asks will we, as transhumanists expect, evolve into... Read More

Germs, bathrooms and door handles...

A story from CTV Ottawa on what you can pick up from a bathroom door handle...and if it could lead to infection. Read More

Is This the Answer to Hospital-Acquired Infections?

I have written quite a bit — probably far too much for the average person’s taste — about the poor state of hand hygiene in hospitals, and the resulting proliferation of bacterial infections. I often think I should shut up already about this problem. After all, it’s been 10 years since the Insti... Read More

House Bill Proposes a Federal Open-Access Policy

Congressman Mike Doyle (D – Penn.) has introduced a bill in the House of Representatives that would require that the results from nearly all publicly-funded research be made available online within six months after they are published in a peer-reviewed journal.

The Federal Research Public Acc... Read More

Birds of a feather don't always respond together to infection

Different populations of the same animal species don’t always use fever to fight infection the same way.

The findings may help scientists predict the locations where diseases carried by animals are most likely to take hold—and could forecast where infections—including those that can have seri... Read More
