Another major goal of synthetic biology is to engineer unnatural molecules and compounds into systems and tools that mimic those found in biology. For instance, Joanna Aizenberg and her laboratory have pioneered using self-assembling synthetic nanofibers to generate capture-and-release devices t... Read More

In the 1800s English poet William Blake famously challenged his readers to “see a world in a grain of sand.” If only he had owned a modern microscope. Thanks to increasingly powerful optical tools, we now know that beneath the skin of every leaf, inside each speck of dirt, and within our own blo... Read More

It causes human mucormycosis and bovine mycotic abortion.
It is distinguished from R.arrhizus by its shorter stalk, and smaller sporangia and spores.
Var.oligosporus : has elongated columellae ; spores less obviously striated.
Var.rhizopodiformis : has ... Read More
For anyone interested in Antibiotic Awareness Week, a big part of the story is that patients (or their parents) demand antibacterials even for viral infections. And doctors often comply, just to get rid of them (the patients, that is). This high-resolution PDF can be printed out for waiting ro... Read More

Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... Read More
