Infants can organise visual information at just four months

...rouping experiments, each baby was placed in a car seat facing a screen onto which images were projected. Overhead cameras recorded how long each infant looked at images on the screen. The infants were shown an array where the stimuli were arranged by similarity in either horizontal lines or vertical colu...

Nano-Probes Allow an Inside Look at Cell Nuclei

...cent labels. This could give biologists a ringside seat to nuclear processes that span several hours or days, such as DNA replication, genomic alterations, and cell cycle control. The long-lived probes may also allow researchers to track the effectiveness of disease-fighting drugs that target these proces...
