There are a variety of machines, consumables, and safety equipment needed to operate a molecular biology lab. And yes, for the vast majority of labs, purified salmon sperm DNA is one of those ...

Scientists are turning DNA into tiny robots that can move, sense, and deliver drugs, pushing nanotechnology closer to ...

A panelist discusses how education and cost are key challenges in ensuring comprehensive molecular testing is performed in a timely manner for patients with ovarian cancer, emphasizing the need for ...

A new single-molecule flow-stretch assay enables real-time observation of DNA-protein interactions to identify the molecular ...

While the central dogma of molecular biology outlines the linear flow of genetic information from DNA to RNA to proteins (black lines), glycomics introduces a “3rd code of life”—glycans—that operates ...

Johns Hopkins University School of Medicine alumnus and former faculty member Hamilton O. Smith, whose 1978 Nobel Prize-winning discovery of restriction enzymes revolutionized genetic engineering, ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

DNA nanostructures store and encrypt data using physical shape, enabling fast electronic readout and secure molecular information processing. (Nanowerk News) Since the dawn of the computer age, ...

Drawing inspiration from natural cell signaling cascades, chemists at Université de Montréal (UdeM) have developed a DNA-based signaling cascade that allows them to quantify and report via an easily ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...
