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 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.
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.
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.
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.
Scientists have discovered genetic evidence of a Neanderthal community living together in Poland 100,000 years ago, including what may be close relatives. This rare snapshot shows how our ancient cousins lived as groups across Europe.

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.
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.
Scientists can now trace trafficked pangolins back to their origins within just a few kilometers using DNA from degraded samples. The breakthrough method is helping authorities identify poaching hotspots and dismantle illegal wildlife trade networks.
A Roman-era skeleton that sparked worldwide debate about ancient migration has revealed her true identity through cutting-edge DNA analysis. The Beachy Head Woman was actually a local Briton, not an African or Mediterranean traveler as scientists once believed.

After 166 years, scientists have finally identified the skeleton of Henry Peglar, a senior sailor from the doomed 1845 Franklin expedition who mysteriously died wearing a steward's uniform. DNA analysis solved a puzzle that has baffled historians since his remains were discovered on a remote Arctic island in 1859.
Scientists have pieced together the genetic story of at least seven Neanderthals who lived together in a Polish cave 100,000 years ago, creating the oldest known snapshot of a prehistoric family. Three of them shared identical DNA, suggesting they were a mother and her children or close maternal relatives.
NASA's Curiosity rover discovered nitrogen-containing molecules similar to DNA building blocks in Martian rock that's been preserving organic matter for 3.5 billion years. It's the strongest hint yet that the Red Planet once had conditions friendly to life.
