A black glove found near the Arizona home of missing 84-year-old Nancy Guthrie has yielded DNA that could be the key to solving the high-profile case, the FBI confirmed Sunday, Feb. 15. Federal investigators say the DNA,

On average, the researchers found 2.65 cDNMs per child in the Chernobyl group, 1.48 per child in the German radar group, and 0.88 per child in the control group. The researchers say those numbers are likely to be overestimates due to noise in the data, but even after making statistical adjustments, the difference was still significant.

In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would later reshape biology and our understanding of life itself.

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots causing messy electrical signals turn out to be something else entirely: twisted coils called plectonemes,
