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.
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.
NASA's Curiosity rover discovered organic compounds on Mars that resemble DNA building blocks, preserved in 3.5 billion year old rocks. The find suggests the Red Planet may have once supported the chemistry needed for life.
Researchers at UC Santa Barbara created a molecule that captures sunlight and stores it as heat energy, no battery required. The breakthrough could revolutionize how we warm our homes and heat water.
Researchers in Tokyo have developed a breakthrough molecule that delivers DNA into cells without causing harmful inflammation, a major obstacle in current gene therapies. Early tests in mice show the new method works up to 14 times better than existing approaches.
NASA's Curiosity rover discovered the richest collection of organic molecules ever detected on Mars, including chemicals similar to those that build DNA on Earth. The 3.5-billion-year-old compounds prove the red planet can preserve delicate chemistry for billions of years.
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.
NASA's Curiosity rover just discovered the most diverse collection of organic molecules ever found on Mars, including seven never seen before on the Red Planet. Among them are chemical building blocks that could be precursors to DNA and RNA.
Scientists discovered all five nucleobases that form DNA and RNA in samples from asteroid Ryugu, suggesting life's essential ingredients exist throughout our solar system. The finding offers new clues about how these crucial molecules may have arrived on early Earth.
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.
NASA's Curiosity rover discovered seven never-before-seen organic molecules in a Martian rock, bringing the strongest evidence yet that ancient Mars had the chemistry needed for life. One molecule found contains the building blocks similar to DNA and RNA.
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.
Researchers discovered a 13-atom molecule containing sulfur in interstellar space, filling a critical gap in our understanding of how life's building blocks formed in the cosmos. The finding suggests many more complex molecules essential to life may be waiting to be found among the stars.
NASA's Curiosity rover discovered the longest organic molecules ever found on Mars, and scientists say they can't explain them without considering the possibility of ancient life. The fatty acid fragments found in ancient mudstone are the kind of molecules living things create.
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.
NASA's Curiosity rover just discovered over 20 organic molecules on Mars, including seven never seen before on the Red Planet. Among them are compounds that form the foundation of DNA and RNA, preserved in ancient clay for billions of years.
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.
NASA's Curiosity rover discovered 21 different organic molecules on Mars, including seven never seen before on the Red Planet. The find brings scientists closer to understanding whether ancient Mars could have supported life.
Scientists at Harvard have created a new DNA origami vaccine that works as well as mRNA shots but doesn't need freezers and is simpler to manufacture. The breakthrough could make life-saving vaccines accessible to millions more people worldwide.
