The death of a woman in China from a strain of bird flu previously unknown in humans is a reminder of the ever-present potential pandemic threat from mutating animal viruses, scientists said on Wednesday.
The new strain, called H10N8, has so far infected only two people - a fatal case in a 73... Read More
Escherichia coli – a friendly and ubiquitous bacterial resident in the guts of humans and other animals – may occasionally colonize regions outside the intestines. There, it can have serious consequences for health, some of them lethal.
In a new study conducted in assistant professor Melha M... Read More
This transmission EM of a thin section of a T2 phage infecting an E. coli cell was produced by Lee Simon in the late 1960’s. It is noteworthy for depicting a remarkably large number of properties of the phage and of the infection process. Can you figure out how many such characteristics are illu... Read More
Lyme disease is often evident by a rash on the skin, but infections do not always produce similar rashes. This can make it difficult to detect the disease early, when antibiotic treatment is most effective. Researchers describe a new mathematical model that captures the interactions between dise...

Scientists at The Scripps Research Institute (TSRI) have invented a new method for designing artificial proteins, and have used it to make key ingredients for a candidate vaccine against a dangerous virus, respiratory syncytial virus (RSV), a significant cause of infant mortality. The virus has ... Read More
Dogs aren’t the only pets who sometimes bite the hands that feed them. Cats do too, and when they strike a hand, can inject bacteria deep into joints and tissue, perfect breeding grounds for infection. Cat bites to the hand are so dangerous, one in three patients with such wounds had to be hospi... Read More
Metagenomic survey reveals traces of pathogens and allergens in the city’s air. For people racked by the dreaded ‘Beijing cough’, it is all too clear that particles in the city’s thick smogs pose a public-health problem. But much less clear is the impact — or even the identity — of the microbes ... Read More
An alternative approach to the traditional introductory laboratory course at the undergraduate level significantly increases student retention rates, according to research published in mBio, the online open-access journal of the American Society for Microbiology.
In 2012, the President's Coun... Read More
In a study to be presented on Feb. 6 at 3:15 p.m. CST, at the Society for Maternal-Fetal Medicine’s annual meeting, The Pregnancy Meeting ™, in New Orleans, researchers will report that cervicovaginal (CV) microbiota differs in the late second and early third trimester in women destined to have ...

Imagine a world where bricks are grown instead of fired: this is the world architect-turn-scientist Ginger Krieg Dosier lives every day. Ginger strives to create an alternate building block that will craft a more sustainable future for the construction industry and in turn help to lower the worl... Read More
The human intestinal tract, or gut, is best known for its role in digestion. But this collection of organs also plays a prominent role in the immune system. In fact, it is one of the first parts of the body that is attacked in the early stages of an HIV infection. Knowing how the virus infects c... Read More
This episode: Bacteria that swarm in the soil cooperate or compete based on one particular protein structure!
(10.5 MB, 11.5 minutes)
Scientists have identified a way some viruses protect themselves from the immune system’s efforts to stop infections, a finding that may make new approaches to treating viral infections possible.
Viruses have well-known strategies for slipping past the immune system. These include faking or s... Read More
Researchers have identified components in Clostridium difficile (C. diff) that may lead to new diagnostic tools, and ultimately more timely and effective treatment for this often fatal infection. C. diff is a spore-forming bacterium that causes severe diarrhea and is responsible for 14,000 death... Read More
Probe identifies staph bacteria without need for biopsies. Chances are you won’t know you’ve got a staph infection until the test results come in, days after the symptoms first appear. But what if your physician could identify the infection much more quickly and without having to take a biopsy a... Read More
Sixty years ago Jacob, Brenner and Cuzin devised their 'Replicon Model', inspiring and useful guideline for replication research ever since. According to the model, a 'Replicon' is a genetic element replicated from a single 'Replicator'—replication origin, in modern terms—and replication is trig... Read More
For the first time ever, a team led by the University of Colorado Boulder has sequenced the internal bacterial makeup of the three major life stages of a butterfly species, a project that showed some surprising events occur during metamorphosis.
The team, led by CU-Boulder doctoral student To... Read More
A unique biotechnology start-up company have developed a method of growing bricks from nothing more than bacteria and naturally abundant materials. Having recently won first place in the Cradle to Cradle Product Innovation Challenge, bioMason has developed a method of growing materials by employ... Read More
In this paper we describe the perspective of following the achievements in medicine, where gut microbiome transplants are proving to be a powerful method to overcome several gastrointestinal disorders and many other physiological problems, to possible solve diseases in plants. There is strong si... Read More
In this blog, I share some "first word that comes to mind" responses of my freshman biology class to the words "germ," "bacteria," "cell," and "DNA." The way that we perceive an idea or concept definitely impacts our relationship with it. Thus, finding out what students think, coming into our ... Read More
