These gene-edited tomatoes grow in grape-like clusters, rather than on long vines.

Gene-Edited Tomatoes Grow in Bunches Like Grapes, Making Them Ideal for Urban Farming

Growing food in urban environments could have important implications for sustainability—if we can produce crops that thrive in tight spaces

A 5,700-year-old piece of birch tar, chewed as gum, contains the genome, mouth microbes, and even dietary information about its former chewer.

Human Genome Recovered From 5,700-Year-Old Chewing Gum

The piece of Birch tar, found in Denmark, also contained the mouth microbes of its ancient chewer, as well as remnants of food to reveal what she ate

A portrait (by Juan Carreño de Miranda) of Charles II, the last of the Spanish Habsburg kings, and his father, Philip IV (painted by Diego Velázquez, of whom the king was a patron). Both men had prominent jaws, which a new study concludes is most likely the result of the family's inbreeding.

The Distinctive ‘Habsburg Jaw’ Was Likely the Result of the Royal Family’s Inbreeding

New research finds correlation between how inbred rulers of a notoriously intermarrying dynasty were and the prominence of their jutting jaw

A newly developed gene therapy is saving young people afflicted by the rare but deadly diagnosis

By genetically modifying a patient's own immune cells to target and kill cancer cells, CAR-T therapy offers a whole new way to fight cancer.

The Possibilities and Risks of Genetically Altering Immune Cells to Fight Cancer

Of the ten or so patients I’ve treated with CAR-T, over half developed strange neurologic side effects ranging from headaches to seizures

Unlike classic CRISPR-based editing, which fully cleaves DNA in two, prime editing starts with a cut to only one strand of the double helix.
