Without enzyme, biological reaction essential to life takes 2.3 billion years

All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these reactions proceed spontaneously, in the absence of enzymes - minutes, hours, days? And why even pose the question?

Medicine, math and engineering combine to reveal how sepsis and less severe infections occur

It's a leading cause of death, but no one knows for sure how and why it happens. It's a major source of health care costs, adding days or weeks to the hospital stays and lost work time of millions of people. But no one fully understands how best to fight it.

New technology to control the motion of bacteria that produce cellulose - biomaterial and medical implant potential

Two Virginia Tech engineers have put bacteria to work as tiny weavers of biomaterials and medical implants.

New analysis of the mechanisms that drive evolution in viruses and bacteria

It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence.

Superbugs on the rise in Canadian hospitals

Although infection control has been substantially ramped up in Canadian hospitals since the SARS crisis of 2003, the number of resistant bacterial infections post-SARS have multiplied even faster, a new Queen's University study shows.

Researchers find new path to antibiotics in dirt

A teaspoon of dirt contains an estimated 10,000 species of bacteria, but it's only one percent of these microbial bugs - the ones that can be grown easily in a lab - that have brought us antibiotics, anticancer agents and other useful drugs.

Persistent bacterial infection exploits killing machinery of immune cells

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

Bacteria can directly cause human blood and plasma to clot

Bacteria can directly cause human blood and plasma to clot - a process that was previously thought to have been lost during the course of vertebrate evolution, according to new research at the University of Chicago, National Institute of Allergy and Infectious Diseases, and Institut Pasteur in Paris. Their findings will be published online Nov. 2 in Nature Chemical Biology.
