The ability to rapidly count and measure features of cells opened the research flood gates.

Modification on a high-resolution fluorescent microscopy technique allow researchers to track the precise movements of motor proteins. 

Machine learning can be harnessed to synthesize artificial light-bearing enzymes that actually work in cells.

A new genetic sensor called PRISM makes use of a host cell’s DNA replication machinery to trigger fluorescence in neurons with damaged DNA.

A new tool called PRISM draws on virus-host interactions and a DNA repair pathway to help researchers visualize how cellular stress may contribute to neurodegenerative disease.

Researchers find that tissue-resident memory T cells in the corneas of mice engender a lasting immune response.

A study in mice finds that for certain genes, one parent’s allele can dominate expression and shape behavior—and which parent’s allele does so varies throughout the body.

A handful of new studies moves the needle toward a consensus on the long-disputed question of whether insect wings evolved from legs or from the body wall, but the devil is in the details.

The Scientist spoke with physicist and microbial ecologist Idan Tuval, whose recent paper challenges the assumption that these single-celled organisms only communicate via chemical signals.

The MIT physicist has demonstrated the importance of clusters of RNA polymerase and other transcription mediators in regulating RNA production.

In CRISPRed fruit flies that lack certain antimicrobial peptides, bacterial infections flourish, as revealed by fluorescent markers.

Under UV light, flying squirrels give off a rosy glow.
