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 […]

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.

In nature, every species must be equipped with a strategy to be able to survive in […]

A watercolor-like illustration of Treponema pallidum, the bacterium that causes syphilis. Credit: Alice C. Gray By shuffling DNA in and out of one gene, syphilis stays a step ahead of the immune system to resist eradication. The bacterium that causes syphilis, Treponema pallidum, likely uses a single gene to escape the immune system, […]

A mosaic world map made from various human teeth. Photographs made at the Osteological Collection, University of Tübingen. (Graphic design: Peter Jammernegg (photographer and graphic designer); Copyright: Katerina Harvati/ University of Tübingen) University of Tübingen researchers uncover dental traits revealing genetic relationships in humans, serving as proxy for DNA. Researchers at […]
