Opening the door to more sophisticated investigation of sperm locomotion and biophysics, researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have identified previously unobserved swimming patterns in human and horse sperm cells.

This research, published in Scientific Reports, a journal of the Nature Publishing Group, could lead to a deeper understanding of how sperm move on their way to fertilization or other functions and how they react when encountering various toxins or chemicals. (more…)

Scientists Discover a New Tiger Shark Hunting Technique

In a joint research effort between the University of Hawaiʻi at Mānoa’s Hawai‘i Institute of Marine Biology (HIMB), University of Tokyo, the Japanese National Institute of Polar Research, and the University of Florida, scientists have shed new light on the hunting behavior of tiger sharks by studying their swimming dynamics off the west coast of Hawai‘i Island.
