A new collagen fingerprinting tool can help scientists identify species from archaeological bone fragments. Pacific islanders of the late Stone Age, also known as the Neolithic period, were master fishers. Archaeological evidence indicates that these groups caught fish both inshore as well as in open waters.

The new Zooarchaeology by Mass Spectrometry (ZooMS) tool can detect the unique chemical fingerprint hidden within collagen, a structural protein that makes up most of bone mass.
The researchers tested 131 archaeological bones and accurately identified three tuna and five shark varieties
Antarctic fish have built a sprawling neighborhood of neatly arranged nests in the Weddell Sea — a surprising display of organization in some of the coldest waters on Earth. The discovery suggests that these fish strategically group their nests to better protect their eggs from predators, adding to evidence that the Weddell Sea harbors complex, vulnerable ecosystems worth preserving, researchers report October 29 in Frontiers.

The Milky Way galaxy is like a gigantic ocean gyre or eddy that spins and wobbles around its center.
But our home galaxy also has a colossal wave rippling through it, pulling and pushing an ocean of stars and cosmic dust in its wake, according to newly released images from the European Space Agency’s Gaia space telescope.
The images show that this wave of motion emanates from the center of the Milky Way and takes up a large portion — a little less than half — of the galaxy’s entire body, which itself is warped in the outer edges. Looking at the galaxy in a vertical sideways view, you see that stars float above or below the disc’s dusty central body, as if they were fish bobbing up and down in a wave of water after a boat passes by.
