Deoxyribonucleic acid, or DNA, holds the genetic info handed from mother and father to offspring. However researchers are pushed by an even bigger query—past inheritance, what extra are you able to do with DNA? The outcomes are mind-bending. From sperm plastic to woolly mammoth meatballs, listed below are ten initiatives that show DNA is a freakishly malleable materials.

10 A Film Inside Micro organism
In 2016, researchers saved 100 bytes of knowledge inside E. coli cells. A 12 months later, they determined to push the boundaries of that experiment—and with good cause. Cells can go the place no human can, and if they might document and replay info like tiny GoPros, medical doctors would possibly sooner or later observe organic adjustments immediately contained in the physique.
In 2017, the group succeeded by encoding 5 frames of Eadweard Muybridge’s traditional Horse in Movement movie into the DNA of an E. coli specimen. Every shaded pixel of the animation was translated into DNA code, which was then embedded into the micro organism’s genome utilizing CRISPR gene-editing know-how. Amazingly, the organisms handed the “film” to their offspring, from which scientists later recovered about 90 % of the photographs intact.[1]
9 The World’s Tiniest Antenna
When scientists unveiled the smallest antenna ever made in 2022, it wasn’t constructed from metallic—it was constructed from DNA. The gadget measured solely 5 nanometers lengthy (one billionth of a meter). Fairly than transmitting radio waves, the antenna tracked the actions of proteins inside dwelling cells.
Proteins always change form as they carry out their work, however these shifts occur too quick to look at simply. The DNA-based antenna makes use of fluorescent gentle indicators to document these adjustments in actual time. By studying the colour of the sunshine that the antenna emits, scientists can observe how particular proteins operate—an innovation that might result in simpler medication and nanoscale medical units.[2]
8 The Smallest Tic-Tac-Toe Board
Laboratory work doesn’t should be boring. In 2018, scientists at Caltech performed a microscopic recreation of Tic-Tac-Toe. It wasn’t a software program simulation—it was constructed from DNA.
The method behind it, known as DNA origami, was invented years earlier to fold strands of DNA into particular nanoscale shapes. Caltech researchers had already used it to create the world’s smallest model of the Mona Lisa. However the Tic-Tac-Toe board had a intelligent twist: it was dynamic. Gamers might transfer their X’s and O’s by rearranging tiny DNA tiles, permitting the board’s sample to vary. The sport took six days to finish, with participant X in the end successful.[3]
7 Folding DNA right into a Masterpiece
A decade after DNA origami first emerged, scientists took it a step additional. At Caltech, they recreated Vincent van Gogh’s The Starry Evening on the nanoscale by folding a single DNA strand into exact shapes, stabilized by shorter strands performing like staples.
The experiment was greater than artwork. Researchers used fluorescent molecules inside microscopic gentle sources known as photonic crystal cavities (PCC), permitting the miniature Starry Evening to glow in numerous hues. This tiny masterpiece demonstrated how DNA origami might function a bodily framework for future nanotechnologies—even perhaps molecular computer systems that course of information utilizing gentle.[4]
6 Rabbit/Plant Air Filters
Airborne toxins linger in practically each house—not simply chemical compounds from cleaners but additionally pollution like chloroform and formaldehyde. Odd houseplants can take in some contaminants, however solely when you’ve got a number of giant crops per 100 sq. toes (9.3 m²). In 2018, the College of Washington revealed a bioengineered resolution that might do the identical work way more effectively.
They modified a standard houseplant, pothos ivy (Epipremnum aureum), with a rabbit gene known as CYP2E1. This enzyme breaks down each chloroform and benzene, two of the most typical family toxins. In lab exams, sealed containers stuffed with these gases confirmed dramatic reductions after three days and had been practically toxin-free after eight. The so-called “bunny ivy” isn’t a substitute for mechanical air filters, however it’s a promising step towards greener indoor air purification.[5]
5 New Viruses Created by AI
Think about asking an AI mannequin to design a organic virus—then watching that code come alive. In 2025, Stanford College researchers educated an AI system known as Evo 2 on genetic information from bacteriophages, viruses that assault solely micro organism. They requested this system to put in writing totally new viral genomes.
The AI typically “hallucinated,” however filters eliminated nonsense sequences. The scientists then synthesized secure DNA fragments and inserted them into E. coli cells. When the sequences had been assembled accurately, they produced functioning bacteriophages that promptly killed their bacterial hosts.
Although nonetheless experimental, this AI-guided strategy might revolutionize drugs. Designer phage therapies would possibly sooner or later fight antibiotic-resistant infections—a disaster projected to trigger as much as 10 million deaths yearly by 2050.[6]
4 New Antibiotics from Extinct People
The battle in opposition to antibiotic-resistant micro organism doesn’t simply depend on futuristic AI. In 2023, researchers turned to the previous, looking for new antimicrobial compounds hidden within the genomes of extinct human kin.
Utilizing synthetic intelligence, scientists examined DNA from Neanderthals and Denisovans, attempting to find peptide sequences with potential antibiotic properties. Six promising molecules emerged—4 from fashionable people and one every from the 2 extinct species. Lab-synthesized variations had been examined on contaminated mice. Some peptides halted bacterial development however didn’t kill it, whereas others worn out pores and skin pathogens when given in excessive doses.
It’s early work, however these findings counsel that misplaced genes from humanity’s historical cousins might assist fashionable drugs battle the subsequent era of superbugs.[7]
3 Plastic from Fish Sperm
Biodegradable plastics are nothing new—cornstarch, algae, and wooden pulp have all been used to interchange oil-based supplies. However in 2021, Chinese language scientists unveiled a bioplastic with a a lot smaller carbon footprint and a really unusual supply: salmon sperm.
They fused strands of salmon DNA with a compound derived from vegetable oil, making a jelly-like hydrogel. As soon as freeze-dried, the hydrogel could possibly be molded into light-weight, inflexible shapes. Not like standard plastics, it dissolves simply in water or with DNA-eating enzymes, reverting to its gel type.
The fabric’s simplicity and low power price make it a sustainable different for short-term packaging—although it most likely received’t change your water bottle anytime quickly.[8]
2 A Mouse Constructed from Pre-Mammal Genes
The genes Sox and POU are important for forming stem cells in mammals. However historical variations of those genes advanced in single-celled organisms lengthy earlier than animals existed. In 2024, researchers determined to check simply how historical life’s blueprints actually are.
They changed the trendy Sox2 gene in mouse stem cells with a primordial model present in choanoflagellates—tiny creatures that symbolize animals’ closest dwelling single-celled kin. Surprisingly, the traditional gene nonetheless labored. When the altered stem cells had been inserted right into a creating mouse embryo, they contributed to tissues within the ensuing animal, producing a chimeric mouse with distinct patches of darkish fur and eyes.
The experiment confirmed that the genetic toolkit for creating complicated life existed practically a billion years earlier than multicellular animals ever appeared.[9]
1 A Woolly Mammoth Meatball
Woolly mammoths vanished after the final Ice Age, however their DNA lives on—and in 2023, it ended up in one thing nobody anticipated: an enormous meatball.
An Australian food-tech firm specializing in lab-grown meat unveiled the creation on the Nemo Science Museum within the Netherlands. To make it, scientists synthesized mammoth myoglobin DNA—the protein chargeable for meat’s taste and colour—and crammed in lacking sequences with genes from African elephants, the mammoth’s closest dwelling kin. The DNA was then inserted into sheep cells, which multiplied into billions of cells that shaped the bottom for the meatball, roughly the dimensions of a volleyball.
The large morsel was slow-cooked and scorched with a blowtorch for show, filling the room with a surprisingly appetizing aroma. No one ate it, although. After 5,000 years with out mammoth protein within the human food plan, even its creators weren’t keen to danger the primary chunk.[10]
