Disease-causing bacteria stink — literally — and the odor released by some of the nastiest microbes has become the basis for a faster and simpler new way to diagnose blood infections and finger the specific microbe, scientists reported here today at the 246th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society. The new test produces results in 24 hours, compared to as much as 72 hours required with the test hospitals now use,...

A new palm-sized microarray that holds 1,200 individual cultures of fungi or bacteria could enable faster, more efficient drug discovery, according to a study published in mBio®, the online open-access journal of the American Society for Microbiology. Scientists at the University of Texas at San Antonio and the U.S. Army Institute of Surgical Research at Fort Sam Houston have developed a microarray platform for culturing fungal biofilms, and validated one potential application of the...

The microbial population in the air of the New York City subway system is nearly identical to that of ambient air on the city streets. This research, published ahead of print in the journal Applied and Environmental Microbiology, establishes an important baseline, should it become necessary to monitor the subway's air for dispersal of potentially dangerous microbes. Also, the combination of new methodologies in the study, including fast collection of aerosols and rapid sequencing technology,...

Scientists Establish Cell Cultures Of Endangered Frog

San Diego Zoo Global Wildlife Conservancy scientists have taken a tremendous leap forward in banking viable amphibian cells. This was achieved through the first successful establishment of cell cultures from frozen biopsy specimens of the critically endangered Mississippi gopher frog. A method called "tissue piecing" and immediate freezing in liquid nitrogen allows field biologists to collect samples that can later be processed in a laboratory. "With amphibians we have found that we can...

Device can be used for medical diagnostics, to image cell growth continuously The cameras in our cell phones have dramatically changed the way we share the special moments in our lives, making photographs instantly available to friends and family. Now, the imaging sensor chips that form the heart of these built-in cameras are helping engineers at the California Institute of Technology (Caltech) transform the way cell cultures are imaged by serving as the platform for a "smart" petri dish....

The new technique yields 3-D cells that more closely resemble those inside the body and could led to improvements in early drug screenings Cells in the human body live in amazingly complex, three-dimensional environments that are crucial for the cells' proper function. The lung, for example, consists of layers of different kinds of cells that work together to exchange oxygen and carbon dioxide between the air and the blood. The way these cells work together, and the chemicals that they...

Stacks of filter paper provide a realistic, easy-to-use medium for growing cells An insight from the labs of Harvard chemist George Whitesides and cell biologist Don Ingber is likely to make a fundamental shift in how biologists grow and study cells "“ and it's as cheap and simple as reaching for a paper towel. Ratmir Derda, a postdoctoral student co-mentored by Whitesides and Ingber at Harvard's new Wyss Institute for Biologically Inspired Engineering, has realized that by growing...
