Heralds a new era for biological research, medical science, and health
Advances in molecular biology and computer science may soon lead to a three-dimensional computer model of a cell, heralding a new era for biological research, medical science, and human and animal health, according to the authors of a paper recently published in the Journal of Molecular Biology. “Cells are the foundation of life,” said Ilya Vakser, … more…

Could improve detection of viruses and speed the process of identifying newly emerging viruses to head off unpredictable outbreaks
Penn State researchers have developed a new portable microdevice that uses a forest-like array of vertically aligned carbon nanotubes to selectively trap and concentrate viruses by their size. It could improve detection of viruses and speed the process of identifying newly emerging viruses. The research, by an interdisciplinary team of scientists at Penn State, was published … more…
