The new species was discovered in the dunes on Lista in Farsund municipality. Credit: Arnstein Staverløkk, NINA, CC BY3.0 A brand new species of parasitic cuckoo wasp was discovered based on its clever use of pheromones. Cuckoo wasps – also called emerald wasps – are some of the most beautiful […]

Biochemists use protein engineering to transfer photocaging groups to DNA. DNA (deoxyribonucleic acid) is the basis of life on earth. The function of DNA is to store all the genetic information, which an organism needs to develop, function and reproduce. It is essentially a biological instruction manual found in every cell. Biochemists […]

Newly described chemical reaction could have assembled DNA building blocks before life forms and their enzymes existed.   ANIMATION Discovery boosts theory that life on our planet arose from RNA-DNA mix. Chemists at Scripps Research have made a discovery that supports a surprising new view of how life originated on our […]

Genes that give plant nucleus its shape discovered, also regulate copper tolerance. Researchers at the University of Tokyo have identified how the architecture of the cell nucleus can change gene activity in plants. This discovery reveals fundamental knowledge about genome regulation and points towards future methods for potentially manipulating the […]

The two atlases map gene expression and availability as cells differentiate into different cell types and tissues. UW Medicine researchers at the Brotman Baty Institute in Seattle have created two cell atlases that track gene expression and chromatin accessibility during the development of human cell types and tissues. An artist’s […]

Researchers “counted” Japanese jack mackerel (Trachurus japonicus) in Maizuru Bay, Japan, through quantitative measurements of environmental DNA concentration. Credit: Reiji Masuda, Kyoto University River water, lake water, and seawater contain DNA belonging to organisms such as animals and plants. Ecologists have begun to actively analyze such DNA molecules, called environmental DNA, to […]

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 […]

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 […]
