After most of the population of the Pacific rim sought higher ground this week, we speak with the architect of the tsunami warning technology. Also how aging Killifish might help us probe our senior moments.
This week, an M8.8 earthquake near Kamchatka in the western pacific led to tsunami evacuation alerts thousands of miles away. Seismologist Judith Hubbard was writing about the area in the days leading up to it, following a M7.4 event 9 days before, which we now know to categorize as a foreshock. As she says, it’s these subduction zones between tectonic plates that give out the most energy, produce the biggest quakes, leading to the worst tsunamis.
Finally, how can a short-lived African freshwater fish help scientists studying senescence? Stanford’s Judith Frydman and colleagues publish this week a study in Science that finds Killifish’s brain cells’ ability to encode proteins degrades with age, in keeping with similar patterns of older human brains. Because Killifish have such brief life cycles, yet seem to follow the brain cycles of most vertebrates, they provide an ideal model species from which to find out more, as she explains.
