Biologists glean insight into repetitive protein sequences

About 70% of all human proteins include at least one sequence consisting of a single amino acid repeated many times, with a few other amino acids sprinkled in. These "low-complexity regions" are also found in most other organisms.

Putting the brakes on 'budding' viruses

Paramyxoviruses have the potential to trigger a devastating pandemic. This family of viruses includes measles, Nipah virus, mumps, Newcastle disease and canine distemper.

Free-space light coupling using curved micromirrors

Micromirrors are micrometer-scale mirrors that are widely used in many applications, mainly in optical-fiber telecommunications, optical scanners, and optical instrumentation. Micromirrors can be integrated within photonic ...

A vertical matrix X-ray detector for multi-energy discrimination

There are three types of cone cells in the retina that are called L-cones (sensitive to red light), M-cones (sensitive to green light), and S-cones (sensitive to blue light). The coordinated response of cone cells to visible ...

Minerals can be key to healing damaged tissue

Every species, from bacteria to humans, is capable of regeneration. Regeneration is mediated by the molecular processes that regulate gene expression to control tissue renewal, restoration and growth.
