Genetics Used to Track Transmission of MRSA Bacteria

New technology has made it possible, for the first time, to track the potentially deadly bacteria MRSA around the world or from one person to another, a new study reports.

The ability to track MRSA (methicillin-resistant Staphylococcus aureus) can help scientists figure out how the bacteria m... Read More

Marshall Nirenberg, Biologist Who Untangled Genetic Code, Dies at 82

Marshall W. Nirenberg, a biologist who deciphered the genetic code of life, earning a Nobel Prize for his achievement, died Friday at his home in Manhattan. He was 82.

The cause was cancer, said his stepdaughter Susan Weissman.

In solving the genetic code, Dr. Nirenberg established the rul... Read More

Llama Proteins Could Play a Vital Role in the War on Terror

Scientists at the Southwest Foundation for Biomedical Research (SFBR) have for the first time developed a highly sensitive means of detecting the seven types of botulinum neurotoxins (BoNTs) simultaneously.

The BoNT-detecting substances are antibodies -- proteins made by the body to fight dis... Read More

Retail Meat Linked to Urinary Tract Infections: Strong New Evidence

Chicken sold in supermarkets, restaurants and other outlets may place young women at risk of urinary tract infections (UTI), McGill researcher Amee Manges has discovered. Samples taken in the Montreal area between 2005 and 2007, in collaboration with the Public Health Agency of Canada and the Un... Read More

Bacteria rewired to flash in sync

Glowing bacteria that flash on and off together are pointing the way towards implants made of engineered cells that would deliver precise doses of drugs or hormones at specific times of the day.

The bacteria have been engineered to fluoresce in synchronised bursts to produce waves ... Read More

Viruses use 'hive intelligence' to focus their attack

This video from Geoffrey Smith and his team of virologists at Imperial College London shows how vaccinia virus spreads through cells. What's interesting about this is that when the virus leaves one cell in search of another to infect, vaccinia would bounce off of or hop over cells that were alre... Read More

Corrosion and fatigue: new ways of warding off old enemies

Materials used for structures in offshore have two main enemies: corrosion and fatigue. In this article Dr David Greenfield and Dr Chris Sammon discuss research into these twin foes.

Scroll down to the end to read about biologically active, 'living' protection for preventing corrosion. Read More

NSF grant to launch world's first open-source genetic parts production facility

With seed money from the National Science Foundation (NSF), bioengineers from the University of California, Berkeley, and Stanford University are ramping up efforts to characterize the thousands of control elements critical to the engineering of microbes so that eventually, researchers can mix a...

Promising Probiotic Treatment For Inflammatory Bowel Disease

Bacteria that produce compounds to reduce inflammation and strengthen host defences could be used to treat inflammatory bowel disease (IBD). Such probiotic microbes could be the most successful treatment for IBD to date, as explained in a review published in the February issue of the Journal of ... Read More

Genomic surveillance of pandemic H1N1

The BC Centre for Disease Control has launched an influenza genome sequencing project to better understand how the pandemic H1N1 flu virus has evolved in British Columbia, and may continue to evolve in the coming months.

This project capitalizes on BC's expertise and capacity in genome sequen... Read More

New Visible Light Photocatalyst Kills Bacteria, Even After Light Turned Off

In the battle against bacteria, researchers at the University of Illinois have developed a powerful new weapon -- an enhanced photocatalytic disinfection process that uses visible light to destroy harmful bacteria and viruses, even in the dark.

Based upon a new catalyst, the disinfection proc... Read More

In sync: Squid, glowing companions march in genetic harmony

Most humans are blissfully unaware that we owe our healthful existence to trillions of microbes that make their home in the nooks and crannies of the human body, primarily the gut.

During evolutionary history, humans and bacteria have forged a mutually beneficial coexistence that provides the... Read More

Malaria bug enters skin using sticky patches

German researchers have worked out how the malaria parasite is able to burrow through the skin and into our body.

The study of sporozoites — the highly mobile stages of the malaria parasite — is published in the January issue of the journal Cell Host & Microbe.

"We show that sporozoite mot... Read More

Painless Plasma Jets Could Replace Dentist's Drill

Plasma jets capable of obliterating tooth decay-causing bacteria could be an effective and less painful alternative to the dentist's drill, according to a new study published in the February issue of the Journal of Medical Microbiology.

Firing low temperature plasma beams at dentin -- the fib... Read More

Friendly Bacteria Love the Humble Apple

Why does an apple a day keep the doctor away? New research published in the open access journal BMC Microbiology contributes to our understanding of why eating apples is good for you.

Microbiologists from the National Food Institute at the University of Denmark fed rats on a diet that was ric... Read More

Early immune response needed for hit-and-hide cancer viruses

Retroviruses such as HIV and HTLV-1 don't hit-and-run, they hit-and-hide. They slip into host cells and insert their own DNA into the cell's DNA, and from this refuge they establish an infection that lasts a lifetime.

But that infection might be much less troublesome and much more manageable ... Read More
