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.
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. #
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.
Researchers solved a mystery that has stumped archaeologists for decades by matching ancient paintings at a Kenyan rock shelter to specific communities using DNA evidence. The discovery reveals nearly 9,000 years of human history painted on a single rock wall.
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.
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.
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."
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 accidentally discovered smallpox DNA in 400-year-old Chilean remains, confirming how the disease reached the Americas. The genetic evidence reveals not just history, but how viruses evolve to survive.
For over a century, archaeologists assumed prehistoric women had little power. Now genetic evidence is revealing female warriors, leaders, and matriarchal societies that challenge everything we thought we knew about the past.

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.
After more than three decades, modern DNA technology has helped Alberta RCMP identify and arrest a suspect in a 1992 sexual assault case. The breakthrough shows how genetic genealogy is giving victims closure and proving that justice has no expiration date.
Researchers discovered traces of two extinct human populations hidden in modern genomes, including a "super-archaic" lineage dating back nearly 2 million years. One ghost ancestor left DNA in all people alive today.
New genetic evidence proves dogs were part of human communities 5,000 years earlier than scientists previously thought. Ancient DNA reveals our best friends have walked alongside us for nearly 16,000 years.
The scientist whose work proved DNA's structure believed science and everyday life should never be separated. More than 60 years after her death, her words offer a refreshing balance between rigorous discovery and human purpose.
Scientists can now use DNA from seized pangolin scales to pinpoint the exact forest where the animal was poached, giving investigators a powerful new weapon against wildlife trafficking networks. For India, where over 8,600 pangolins have been seized since 1991 but only 1.4% of cases end in conviction, this breakthrough could finally help connect the dots.
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.
