International scientists and Ngātiwai, a Māori tribe, teamed up to sequence the genome of a rare reptile, the tuatara, uncovering some unique aspects of the tuatara’s evolution. The genome sequence will enable comparative studies to better understand the evolution of the tuatara and its distant relatives: other reptiles, birds, and […]

Credit: Bryan Calk, Macaulay Library, Cornell Lab of Ornithology Baltimore and Bullock’s Orioles Are Not Merging A half-century of controversy over two popular bird species may have finally come to an end. In one corner: the Bullock’s Oriole, found in the western half of North America. In […]

Animation When cells don’t divide into proper copies of themselves, living things fail to grow as they should. For the first time, scientists now understand how a protein called TANGLED1 can lead to accurate cell division in plants. Inside cells are structures called microtubules, which act like highways for moving […]

Gardenia’s newly sequenced genome highlights how evolutionary tinkering transforms plants into some of nature’s great chemical-makers. Plants are some of nature’s most extraordinary chemists. Unlike animals, they can’t run from predators or pathogens. They can’t uproot themselves to seek out a mate or spread their seeds. So instead, they manufacture […]

An international team of scientists have identified candidate resistance genes that could protect ash trees from the Emerald Ash Borer (EAB), a deadly pest that is expected to kill billions of trees worldwide. In the new study, published recently in Nature Ecology & Evolution, researchers from Queen Mary University of London […]

Scientists have long debated which genetic information carrier — DNA or RNA — started life on Earth, but a new study suggests life could have begun with a bit of both. The research, led by scientists from the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB), in Cambridge, shows for the first time […]

DNA may not be life’s instruction book, but just a jumbled list of ingredients. University of Maryland researcher develops potentially revolutionary framework for heredity and evolution in which inheritable information is stored outside the genome. The common view of heredity is that all information passed down from one generation to […]

Stone artifacts from the Initial Upper Paleolithic at Bacho Kiro Cave: 1-3, 5-7 Pointed blades and fragments from Layer I; 4 Sandstone bead with morphology similar to bone beads; 8 The longest complete blade.

Plant scientists have long known that crop yield is proportional to the dose of nitrogen fertilizer, but the increased […]

A cellular pathway in plants to sense danger signals and elicit a response. Credit: Tokyo University of Science Scientists uncover how oral secretions of the cotton leaf worm trigger defense responses in a plant. In nature, every species must be equipped with a strategy to be able to survive in […]
