Resurrection biology — the endeavor to revive strings of molecules and more complex organisms — is making strides in laboratories globally.

While far from the genetically engineered dinosaurs of "Jurassic Park," scientists aspire to de-extinction, resurrecting lost animals and plants. Some researchers explore ancient pathogens, seeking new drugs or sounding alarms, while others recreate elements of human history to understand our ancestors.

1. Reviving 'Zombie' Viruses

Warmer Arctic temperatures thaw permafrost, potentially awakening dormant viruses after thousands of years. Professor Jean-Michel Claverie aims to understand risks by resurrecting viruses from Siberian earth samples. His research isolates ancient viruses, revealing potential public health threats.

2. Hunt for New Antibiotics

Presidential Assistant Professor César de la Fuente mines ancient DNA for bacteria-fighting peptides. Using Neanderthal and ice age creature DNA, he identifies compounds for battling drug-resistant superbugs, addressing urgent global health concerns.

3. Resurrecting the Dodo and More

Colossal Biosciences aims to revive extinct species like the dodo, woolly mammoth, and Tasmanian tiger. By editing pigeon DNA with desired traits, they plan to create hybrid birds resembling the extinct species, potentially influencing conservation efforts.

4. Recreating Ancient Scents

Researchers at Denmark’s Moesgaard Museum recreate the scent of an Egyptian mummification balm from 3,500 years ago. Analyses of canopic jars' residues reveal beeswax, plant oils, resins, and more. The scent, recreated with a perfumer's help, offers a tangible connection to the ancient world. <
