Scientists built an AI that designs synthetic DNA switches capable of turning genes on and off in specific cells, potentially transforming how we treat diseases like leukemia. In lab tests, these AI-generated sequences actually outperformed natural DNA at reactivating a protective gene in leukemia cells.
Scientists created a silicon chip that writes 64 DNA sequences at once using only water and electricity, replacing a toxic chemical process. The breakthrough could lead to portable DNA labs and even DNA-based data storage.
Scientists discovered a bacterial protein that creates DNA without copying existing genetic material—something biology textbooks say shouldn't be possible. The breakthrough could lead to revolutionary new tools for building custom DNA molecules.
A breakthrough AI tool from Google DeepMind can read massive DNA sequences with single-letter precision, helping scientists predict how genetic changes lead to diseases like cancer. The free research tool is already helping researchers understand the 98% of human DNA once dismissed as "junk."
Scientists discovered all five building blocks of DNA on asteroid Ryugu, suggesting the ingredients for life might be common throughout our solar system. The findings support the possibility that life's essential components could have arrived on Earth from space.
Frozen droppings from prehistoric squirrels in Canada's Yukon have revealed DNA from woolly mammoths, ancient big cats, and dozens of other ice age creatures. The 700,000-year-old genetic material ranks among the oldest DNA ever recovered, offering scientists an extraordinary window into ancient life.
Victoria Foe discovered that the DNA scientists dismissed as "junk" may actually be a crucial timing device that makes complex life possible. Her decades-long quest, fueled by personal loss and scientific curiosity, is rewriting what we know about evolution.
Researchers are creating microscopic robots made from DNA that could one day deliver drugs directly to diseased cells and capture viruses in the bloodstream. While still experimental, these molecular machines represent a breakthrough in combining biology with robotics.
Scientists in Mumbai have cracked a way to make antibiotic-resistant bacteria vulnerable again using specially designed DNA sequences. The breakthrough could restore the power of older antibiotics that bacteria learned to defeat.
Caltech researchers invented Sidewinder, a breakthrough method that stitches together short DNA pieces like numbered pages in a book, enabling scientists to build complete genes in hours instead of years. This breakthrough could revolutionize personalized medicine and sustainable materials.
A rejected doctoral student watching a dog inspired a breakthrough that lets scientists recover DNA from dirt, unlocking secrets about ancient humans without needing rare fossils. Twenty years later, his "stupid idea" has transformed how we study human origins.
A new method has revealed that all living humans carry DNA from a mysterious extinct human group that interbred with our ancestors before they left Africa. The discovery rewrites our understanding of human evolution and proves we're connected to relatives we've never even found fossils for.
A Malawian company is breaking down barriers to essential services that were once expensive and out of reach. DNA testing and background checks are now accessible across the country through simple cheek swabs and local clinics.
FBI investigators found crucial DNA evidence on a glove near an 84-year-old Arizona woman's home, bringing new hope to solving her January disappearance. The discovery could finally identify the masked suspect caught on camera.
A new study shows melatonin supplements help night shift workers repair DNA damage by 80% during sleep. The discovery could offer a simple way to protect millions who work overnight from long-term health risks.
Scientists discovered why people with the APOE2 gene live longer and rarely get Alzheimer's: their brain cells are better at repairing DNA damage. The breakthrough could lead to new treatments that protect everyone's brain, especially those at higher risk.

Scientists discovered a rare giant squid and 225 other species in deep ocean canyons off Western Australia without seeing a single creature. They simply collected water samples and analyzed the DNA left behind by marine animals.
University of Missouri researchers have solved a major roadblock in DNA data storage by making it rewritable for the first time. This breakthrough could transform how we store everything from family photos to corporate archives in molecules smaller than a grain of sand.
Scientists discovered that a common DNA repair gene, when overproduced, makes tumors vulnerable to treatments previously reserved for rare inherited cancers. The finding could help 20-30% of breast and ovarian cancer patients access more effective therapies.
Scientists discovered 200,000-year-old horse DNA at a German archaeological site where ancient genetic material shouldn't have survived. The find could unlock genetic secrets from thousands of previously unexplored archaeological sites worldwide.
