Even with passive regeneration, these Velcro-like attachments are so strong that they hold onto proteins for more than 20 hours, making it impossible to measure real-time fluctuations in the blood.

In addition, natural fluctuations and ocean feedbacks may have contributed.

But climate change has led to temperature fluctuations, breaking up ice and in some cases driving bears inland to look for food.

The erratic generators may have created additional power fluctuations that trip the ship's breakers - a common occurrence faced by seafarers, but which mostly takes place in open waters.

The researchers propose that spiders may triangulate the insects’ distance and direction using hairlike structures on their legs called trichobothria that pick up minute fluctuations in sound and air currents.
