Trick that aids viral infection is identified

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

Components in C. diff identified that may lead to better treatment

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

A quicker, cheaper way to detect staph in the body

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

Adhering To The 'Replicon Model' The Sloppy Way

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

CU-Boulder researchers sequence world’s first butterfly bacteria, find surprises

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

Bricks Grown From Bacteria

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

Bespoke microbiome therapy to manage plant diseases

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

Using Wordcloud-Reponses to Discover How Students Perceive Concepts in the Classroom

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

As Plant Virus Jumps to Bees, Does it Cause Colony Collapse?

Another potentially significant answer in the long-running mystery behind colony collapse disorder (CCD) may have just emerged: Researchers have found a virus that typically infects plants has been systemically infecting honeybees in the United States and China.

Quorum sensing genes discovered in a bacteriophage genome?

Recently, the discovery that certain bacteriophage encode bacterial gene silencing systems (CRISPR) that can counteract host defense systems demonstrated how mind boggling the evolutionary pathways between phage and bacterial host actually are. In this publication, these relationships are exten... Read More

3D cell culture set for space

Growing cells – in a laboratory in space or on earth – forms a fundamental basis of modern microbiology, supporting everything from culturing microbes to novel drug design and growing human tissues for use in research and development. The problem is that cells grown on a 2D Petri dish do not ... Read More

Bacterial Toxin a Potential Trigger for Multiple Sclerosis

Researchers from Weill Cornell Medical College have added to the growing body of evidence that multiple sclerosis may be triggered by a toxin produced by common foodborne bacteria. The presented their research at the 2014 ASM Biodefense and Emerging Diseases Research Meeting.

Bacterial Fuel

Imagine a world where greenhouse gases were reduced to a minimum, or where methane released from oil spills could be cleaned in an instant, or where we could develop fuel using only bacteria. Thanks to a discovery by UW researchers, a certain type of bacteria that lives off of methane is able to... Read More

Healthy Bacteria May Lead to Long Life

In the past few years, scientists have begun to uncover the multitude of ways in which the community of bacteria living in the our intestines, known as the microbiome, can impact our health. Not only do these (benign) bacteria help with metabolism and digestion, shifts in it are linked to a wide... Read More

New, unusually large virus kills anthrax agent

From a zebra carcass on the plains of Namibia in Southern Africa, an international team of researchers has discovered a new, unusually large virus (or bacteriophage) that infects the bacterium that causes anthrax. The novel bacteriophage could eventually open up new ways to detect, treat or deco... Read More

How to Make Electricity With Bacteria-Coated Rubber

In the experiment, published this week in Nature Nanotechnology, the researchers slathered one side of a sheet of rubber with the bacterial spores. When the sheet dried it curled up, much like a leaf does after it falls from a tree. Increasing the humidity caused the sheet to straighten out agai... Read More

Cyanine dyes - Non-sulfonated and Sulfonated cyanines Lumiprobe explains

Sulfonated and non-sulfonated cyanines exhibit very similar fluorescent properties. Non-sulfonated cyanines must be dissolved in organic co-solvent (DMF or DMSO) prior to use, and added to a solution of target molecule in aqueous buffers. Recommended volume of co-solvent should be 10% for Cy3, C... Read More
