Microbiologists from Trinity College Dublin have discovered that an identical protein is used differently by two species of bacteria to help them cope with distinct types of environmental stress. The discovery reveals an extraordinary level of versatility in the way different genes are ‘switched... Read More
An international study led by The University of Queensland has tracked a potentially devastating multi-drug resistant E. coli strain that is only one gene away from being resistant to almost all antibiotics.
UQ Australian Infectious Diseases Research Centre scientist Dr Nouri Ben Zakour said ... Read More
Researchers at the Division of Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with an efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofib... Read More
It doesn’t take long for the flu virus to outsmart Tamiflu. EPFL scientists have developed a tool that reveals the mutations that make the virus resistant, and they have identified new mutations that may render ineffective one of the few treatments currently available on the market.
Tamiflu ... Read More
Researchers at Oregon State University have discovered novel proteins in, or on the surface of the bacteria that causes gonorrhea, which offer a promising new avenue of attack against a venereal disease that is showing increased resistance to the antibiotics used to treat it.
Only a single, t... Read More
Methane-producing microbes may be responsible for the largest mass extinction in Earth’s history.
Evidence left at the crime scene is abundant and global: Fossil remains show that sometime around 252 million years ago, about 90 percent of all species on Earth were suddenly wiped out — by far ... Read More

Some natural types of fungus appear to inhibit the build-up of tau—a protein linked to Alzheimer’s disease and other neurodegenerative diseases.
“Tau is a protein that is produced by the body,” says T. Chris Gamblin, associate professor of molecular biosciences at the University of Kansas. “I... Read More
I haven't read it (yet) but heard Daniel Keyes' 1960 short story/1966 novel is a sci-fi masterpiece.
And it's the first place my mind went upon reading about this fascinating breakthrough by researchers at Yale. Read More
By tracing the evolutionary origin of a drug-like protein ring found in sunflowers, Australian and US scientists have discovered a diverse, 18-million-year-old group of buried proteins in daisy seeds.
Researchers at The University of Western Australia, working with academics from The Universi... Read More
The humble baker's yeast has been enlisted to serve the needs of humanity, responsible for beer, wine and bread, among other staples. A domesticated servant for at least millennia, the microscopic fungus has now had one of its chromosomes swapped out by a host of undergraduate students in favor ... Read More
It's long been know that microbes are to blame for food going off and becoming rotten but in the late 1970's, Dan Janzen of the University of Pennsylvania, and a winner of ecology's version of the Nobel Prize, suggested that making something rotten may be to the advantage of the microbes living ...

A virus that invaded the genomes of humanity's ancestors millions of years ago now plays a critical role in the embryonic stem cells from which all cells in the human body derive, new research shows.
The discovery sheds light on the role viruses play in human evolution and could help scientis... Read More
Over 4.5 billion years ago, the Earth was a superheated sphere of molten rock, radiating heat to space at over 2000 K. A billion years later, it had global oceans, teeming with microorganisms. In that time, the Earth underwent massive geological changes, somehow serendipitously creating conditio... Read More
How handy would it be if, instead of taking your broken circuit board to the Genius Bar (again), you could just prompt it to heal itself? That’s the futuristic possibility researchers have recently inched ever so slightly toward, with the development of hybrid “living materials” made from bacter... Read More
When studying bacteria it is quite easy to get fascinated with them as a laboratory specimen while forgetting the huge impact they can have in real life societies. I find the PLoS journal of Neglected Tropical diseases redresses that as it covers work with bacteria and parasites from the front l... Read More
Underground in places nobody likes to look, bacteria are doing terrible things to our sewage pipes. The concrete pipes that carry our waste are literally dissolving away, forcing engineers into a messy, expensive battle against tiny microbes.
"The veins of our cities are in serious trouble, a... Read More
A bill to track drug-resistant infections has been introduced in Florida, inspired in part by FRONTLINE’s Hunting the Nightmare Bacteria.
The bill, sponsored by Rep. Janet Adkins, a Republican, requires the state health department to maintain an online record of the type and location of any a... Read More
