A new way for the heart and brain to ‘talk’ to each other, and Earth’s future weather written in ancient coral reefs
Feb 1, 2024
Veronica Egger, a professor of neurophysiology, discusses her research on how the pulse of blood affects neurons in the brain. They explore the potential for mechanical pulses as a communication method within the body. Also, the podcast explores drilling on a hazardous reef terrace for climate research in Vanuatu to study coral records of past climate patterns.

Unlocking the Past: How Ancient Coral Samples Shed Light on El Nino's Behavior
Researchers are studying ancient corals from the Pacific island of Vanuatu to better understand the behavior of El Nino. By examining corals that have been pushed above sea level due to geological activity, scientists have been able to extract valuable climate records from the last ice age. These records can provide insight into how El Nino may change in the future and help improve long-term climate predictions. Despite facing challenges such as hazardous drilling conditions and unpredictable weather, researchers have managed to collect promising coral samples and are planning to continue their efforts in May to further strengthen the climate record.
