Researchers discovered bacteria that create DNA using proteins as templates instead of other DNA—reversing biology's fundamental rules. This breakthrough could reshape our understanding of how life stores and transfers information. #
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.
California just made it easier for families to find missing loved ones by expanding its DNA program to identify living people, not just the deceased. The new law also preserves DNA samples longer, giving hope to families who've waited years for answers.
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.
Scientists created a computer made entirely from DNA that performs calculations using billions of molecules in a tiny water droplet. The system uses less energy than traditional computers by letting physics guide molecules to the right answer.
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 have discovered evidence of two previously unknown human ancestors hidden in the DNA of people alive today. One interbred with humans in Africa over 50,000 years ago, while another dates back 1.8 million years.
Japanese scientists have developed a silver nanoparticle technique that makes assembling DNA up to five times more efficient than traditional methods. The breakthrough could eventually simplify creating gene therapies, cancer vaccines, and improved crops.
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.
Researchers discovered that Alzheimer's disease disrupts how DNA folds inside brain cells, revealing a completely new aspect of the disease. This breakthrough could open doors to treatments that work in ways scientists never considered before.

Your DNA carries traces of mysterious extinct relatives who interbred with humans hundreds of thousands of years ago. Scientists just figured out when these ancient cousins joined our family tree.
New research shows that fixing damaged DNA might be the key to living healthier for longer. Scientists are exploring whether boosting our body's natural repair systems could slow down aging itself.
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.
Researchers found that losing just one copy of a heart development gene disrupts how DNA folds inside cells, potentially explaining why the same genetic mutation causes different birth defects. The discovery could transform how we understand and treat congenital heart disease.
