Cornell scientists have engineered E. coli to act as a sensitive biosensor for monitoring environmental arsenic, a toxic pollutant most notably found in rice paddies in Southeast Asia. Their new study ...

After shrinking each game frame down to a 32×48 black-and-white bitmap, Ramlan describes a system whereby a display controller uses a well-known chemical repressor-operator pair to induce each ...

Filamentous fungi are highly productive cell factories, many of which are industrial producers of enzymes, organic acids, and secondary metabolites. The increasing number of sequenced fungal genomes ...

The study of different genes, chromosomes and the spatiotemporal relationship between them is of great significance in the field of biomedicine. CRISPR-Cas9 has become the most widely used gene ...

Glomerular capillaries are lined with a highly specialized fenestrated endothelium and contribute to the glomerular filtration barrier. The Notch signaling pathway is involved in regulation of ...

The excessive use of antibiotics in human and veterinary medicine causes the emergence of multidrug resistant bacteria. In this context, the surveillance of many different antibiotics provokes a ...

Prokaryotic regulatory proteins respond to diverse signals and represent a rich resource for building synthetic sensors and circuits. The TetR family contains >10 5 members that use a simple mechanism ...

We have performed single-molecule studies of GFP–LacI repressor proteins bound to bacteriophage λ DNA containing a 256 tandem lac operator insertion confined in nanochannels. An integrated photon ...
