In the latest episode of Quirks & Quarks with Bob McDonald, scientists have made a significant discovery regarding the behavior of ancient sea monsters through the study of fossilized vomit. The plesiosaur, a formidable marine predator from the Jurassic era, was known for its large size and unique feeding habits. Analysis of 150 million-year-old vomit found in North Sea sediments sheds light on how these creatures interacted with their environment and diet. Geologist Dirk Knaust from Equinor recently published these findings in Geological Magazine.
Moving on to a different topic, the remarkable story of Jonathan, a 194-year-old Aldabra giant tortoise, has captivated researchers. Jonathan, who holds a Guinness World Record as the oldest-known land animal, has sparked interest in longevity studies. Dr. Stephen Clark and his team delved into Jonathan’s genome to uncover insights into his exceptional lifespan. Their research, detailed in Science Advances, revealed similarities in gene regulation between Jonathan and much younger tortoises.
Furthermore, a breakthrough in timekeeping technology has been achieved with the creation of nuclear clocks by two separate scientific teams. These nuclear clocks, more precise than atomic clocks, operate by exciting a neutron in an atom’s nucleus. This innovation, detailed in Nature by Thorsten Schumm from the Vienna University of Technology, opens new possibilities for applications ranging from GPS technology to dark matter research.
Lastly, the escalating threat of extreme wildfires has prompted researcher Crystal Kolden to explore nature-based solutions to combat these natural disasters. A study from Simon Fraser University warns of the substantial economic impact of climate change-induced wildfires in Canada. Kolden, now an Eddie Goldenberg Research Chair at the University of British Columbia-Okanagan, aims to leverage nature’s resilience to mitigate the increasing risks posed by wildfires.
