Many of the best methods available for monitoring biological binding events can't be used in a diverse range of clinical samples. An ultrasensitive assay based on magnetic signals overcomes this problem.

The Matrix and its two sequel films explore the complex reality of an eponymous cyber-generated world that allows machines to dominate humans. This science-fiction trilogy was famous for its distinctive visual effects, which were generated using innovative combinations of previously existing photographic techniques.
