Phys.org / Why and how birdsong differs across the world—and the eight motifs that tie them together

Birdsong carries meaning across open space, helping birds attract mates, defend territory and communicate with rivals. While there has been much research into the use of birdsong across species, researchers have lacked a ...

Phys.org / Astronomers catch massive galaxy assembling piece by piece 1.2 billion years after Big Bang

Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's largest galaxies formed. The paper outlining the ...

Phys.org / How fishing may be changing one fish species at the molecular level

The pearly razorfish (Xyrichtys novacula) is a small marine animal that lives in sandy coastal waters and feeds on creatures like shrimp. Known locally in Spain's Balearic Islands as raors, it is a popular dish in many homes ...

Phys.org / Why evolution never produced mammal teeth that slice and crush equally well

Evolution is all about trade-offs. Traits that may be beneficial in one situation may backfire in another. Over millions of years, species can become specialized for one way of living rather than being equally good at everything. ...

Phys.org / Plumage reflectance framework offers new insight into how birds evolved heat-controlling feathers

Birds can inhabit various environments with different climates and temperatures, ranging from cold polar regions to scorching hot deserts. To survive and thrive in these very different environments, they need to effectively ...
