    Record breaking observations at a depth of 172 metres shed light on how hard coral survives without light

    In shallow water, less than 30 meters, the survival of hard corals depends on photosynthetic unicellular algae (zooxanthellae) living in their tissues. But how does the coral adapt at depth when the light disappears? French researchers from the CNRS, EPHE-PSL and their international collaborators, associated with Under the Pole (Expedition III), have studied for the first time the distribution of…

    Jupiter flung the dinosaur-killing comet into Earth, new study suggests

    It has long been agreed that the Chicxulub impactor, a space rock that crashed into the Earth 66 million years ago, was responsible for triggering the catastrophic global events that wiped out the dinosaurs. The impact left behind a crater off the coast of Mexico’s Yucatan Peninsula that measures 150km across and 20km deep, and is thought to have triggered…

    Palaeolithic musical instrument played for the first time in 17,000 years

    For the first time in more than 17,000 years, three musical notes have reverberated from an ancient conch shell modified to serve as a wind instrument. Archaeologists say the specimen is the oldest known human-made conch shell horn and stands out as a unique find among European Upper Palaeolithic (around 46,000 to 12,000 years ago) artefacts. First found in 1931…

    Poorer mental health smolders after deadly, devastating wildfire

    In 2018, a faulty electric transmission line ignited the Camp Fire in Northern California, ultimately consuming 239 square miles and several communities, including the town of Paradise, which was 95 percent destroyed. At least 85 people died. Structures have been rebuilt, but some things are worse. In a paper published February 2, 2021 in the International Journal of Environmental Research…

    50 years ago, scientists made the case for a landlubbing Brontosaurus

    Swamp-dweller or landlubber? – Science News, January 30, 1971 Through the years paleontologists have evolved a picture of the appearance and habits of various dinosaurs…. Giant herbivores with long necks and tails, such as the Brontosaurus, have almost invariably been presented as swamp-dwelling semiaquatic animals.… A young Yale University paleontologist, however, now maintains that the anatomy of the Brontosaurus points…
