Today:Early fog in the far southwest clears quickly. Most areas stay dry with sunshine and variable cloud, though northern and northeastern regions may see isolated showers. Light winds overall, ...

Diastereomers are structurally identical molecules that are not mirror images of each other. Diastereomers can have different biological activities, potencies or toxicities, which means they can ...

Researchers at the California NanoSystems Institute at UCLA published a step-by-step framework for determining the three-dimensional positions and elemental identities of atoms in amorphous materials.

Rocky planets are very common around other stars, with tens of billions predicted to exist in our Galaxy alone. Until recently, however, it was not possible to characterize these planets in detail, or ...

Reactive oxygen species (ROS) play a pivotal role in many cellular processes and can be either beneficial or harmful. The design of ROS-sensitive fluorophores has allowed for imaging of specific ...

A central issue in understanding photocatalytic water splitting on a stoichiometric or defective nanostructured oxide surface is its adsorption mode and related reactivity. More than just improving ...

The spliceosome is a dynamic molecular machine 1,2 that catalyses pre-mRNA splicing in two sequential transesterifications analogous to group II intron self-splicing 3. The major spliceosomal ...

The residual metal content of CzrA and NmtR was determined by using a Perkin–Elmer AAnalyst 700 atomic absorption spectrophotometer operating in flame mode. The total metal content of purified ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
