Method speeds up time to analyze complex microscopic images

Cryo-electron tomography permits researchers to study in detail the microscopic structures inside of cells. Researchers who typically required a week of effort to dissect the 3-D structure of a single cell will now be able ...

Optimizing cyanobacteria for biofuel production

Cyanobacteria have attracted significant attention as potential biocatalysts for production of clean energy and green chemicals from sunlight and atmospheric CO2. A recent study investigated effects of altering large cellular ...

Bright red fluorescent protein created

After years of trying, biologists have succeeded in creating an extremely bright red fluorescent protein in the lab. This is good news for researchers, including cancer and stem cell researchers, who use fluorescent proteins ...

Small and extremely resilient—the secrets of black fungi

Highly resistant to stresses, black fungi are real champions among microorganisms. With the support of the Austrian Science Fund FWF, a research team in Vienna discovered that the fungi owe their qualities to hitherto unknown ...

Barcodes to identify gene regulators

The same DNA is present in every cell of an organism, but only some genes are expressed in a given cell. These genes are activated by proteins called transcription factors, in response to various biological signals. Transcription ...

Researchers develop a small-molecule switch to activate proteins

From growing teeth, bones, and tissue in skin and organs to creating enzymes and hormones, proteins are one of the most diverse and important elements of living organisms. But those varied purposes, along with the interconnectivity ...
