It’s not just genes — parents can pass down longevity another way

New research in the roundworm C. elegans shows how changes in the parent’s lysosomes that promote longevity are transferred to its offspring. The work describes a new link between lysosomes — cellular organelles once thought to be the cell’s recycling center — and the epigenome — a set of chemical marks that modify gene expression. […]

Birds around the world share a mysterious warning cry

Birds separated by vast geographic distances and millions of years of evolution share a remarkably similar learned vocal warning to identify parasitic enemies near their nests, an international team of researchers has found. The results represent the first known example of an animal vocalization that is learned from an innate response shared across multiple species. […]

Hidden for 70 million years, a tiny fossil fish is rewriting freshwater evolution

The fossil of a tiny fish found in southwestern Alberta provides new insight into the origin and evolution of otophysans, the supergroup of fish that includes catfish, carp and tetras, which today account for two-thirds of all freshwater species. The specimen, studied by researchers at Western University, the Royal Tyrrell Museum of Palaeontology and international […]

Scientists uncover a mysterious Jurassic lizard with snake-like jaws

New research has uncovered a species of hook-toothed lizard that lived about 167 million years ago and has a confusing set of features seen in snakes and geckos — two very distant relatives. One of the oldest relatively complete fossil lizards yet discovered, the Jurassic specimen is described in a study, published on October 1 in […]

Before they sucked blood, leeches were ocean hunters

A newly described fossil reveals that leeches are at least 200 million years older than scientists previously thought, and that their earliest ancestors may have feasted not on blood, but on smaller marine creatures. “This is the only body fossil we’ve ever found of this entire group,” said Karma Nanglu, a paleontologist with the University […]

The billion-year reign of fungi that predated plants and made Earth livable

New research published in Nature Ecology & Evolution sheds light on the timelines and pathways of evolution of fungi, finding evidence of their influence on ancient terrestrial ecosystems. The study, led by researchers from the Okinawa Institute of Science and Technology (OIST) and collaborators, indicates the diversification of fungi hundreds of millions of years before […]

Black mamba venom has a deadly hidden second strike

A breakthrough study at The University of Queensland has discovered a hidden dangerous feature in the Black Mamba one of the most venomous snakes in the world. Professor Bryan Fry from UQ’s School of the Environment said the study revealed the venoms of three species of mamba were far more neurologically complex than previously thought, […]

Fossils in germany reveal a Jurassic sea monster with a swordfish snout

An international research team from Switzerland and Germany, led by Gaël Spicher (JURASSICA Museum, Porrentruy, Switzerland), has described a new ichthyosaur species based on fossils curated at the Urwelt-Museum Oberfranken (Bayreuth, Germany). The study was published in Museum für Naturkunde Berlin’s open-access journal Fossil Record. The new species was named Eurhinosaurus mistelgauensis, in reference to […]

Mushrooms evolved psychedelics twice, baffling scientists

“This concerns the biosynthesis of a molecule that has a very long history with humans,” explains Prof. Dirk Hoffmeister, head of the research group Pharmaceutical Microbiology at Friedrich Schiller University Jena and the Leibniz Institute for Natural Product Research and Infection Biology (Leibniz-HKI). “We are referring to psilocybin, a substance found in so-called ‘magic mushrooms’, […]
