Taxi and Ambulance Drivers Show Lower Alzheimer's Death Rates: Study

A Harvard Medical School study found lower Alzheimer's death rates among US taxi and ambulance drivers (1.03% and 0.91%) compared to the general population (1.69%) and other transportation jobs, suggesting that memory-intensive navigation might offer some protection against Alzheimer's, though more ...

How might the cognitive demands of taxi and ambulance driving contribute to the observed differences in Alzheimer's death rates?

The lower Alzheimer's death rates among taxi and ambulance drivers may be linked to the memory-intensive nature of their jobs, requiring constant spatial navigation. This aligns with previous research showing hippocampal changes in London taxi drivers. However, the study doesn't prove causality.

Has the new system been used in real-life rescue operations?

The project has already been used successfully in real-life rescues, including one where two people trapped in a flooded car were saved using the new charting system. The system shows great potential for improving safety in the world's 13 million hectares of tidal flats.

Updated World Magnetic Model Shifts Magnetic North Pole Towards Siberia

The World Magnetic Model (WMM) was updated on January 1, 2025, shifting the magnetic North Pole closer to Siberia by approximately 170 km since 2019 due to erratic changes in Earth's magnetic field, impacting global navigation systems.

What are the underlying geological factors causing the unprecedented speed and erratic movement of the magnetic North Pole?

Erratic changes in Earth's magnetic field, exceeding historical patterns, caused the need for an unscheduled WWM update in 2019. The current shift toward Siberia, potentially reaching 390–660 km further in the next decade, is attributed to fluctuating magnetic flux beneath Canada and Siberia.
