After receiving an intraocular injection of the gene for a light-sensitive protein, a 58-year-old man diagnosed with the neurodegenerative eye disease retinitis pigmentosa was able to locate objects on a table using engineered goggles.

Researchers find that SARS-CoV-2 variants can evade primer-probe sets and recommend that diagnostic assays include multiple targets for reliability.

Single-cell RNA sequencing helps to catalog the dozens of cell types present in a stony coral, including its elusive immune cells.

While regeneration has long been the domain of colonial tunicates, a solitary species of sea squirt was able to regenerate into multiple, fully functional individuals within a month of being cut up.

Tumor cells missing a critical protein enter neighboring cells to sap their nutrients, then exit those hosts as intact cells, possibly primed to metastasize. Other scholars say it’s too early to know this for sure.

A controversial idea from the mid-20th century is attracting renewed attention from researchers developing theories for how cognition arises with or without a brain.
