Phys.org / From carp to crocodilians: Why deliberately introduced freshwater giants may bring hidden risks

More than 40% of extant large freshwater animals (megafauna), including carp, salmonids, crocodilians, turtles, beavers, and hippopotamuses, have been deliberately introduced outside their natural range, often for economic ...

Phys.org / 2D topological Kondo insulator observed in a moiré superlattice

When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated with the intrinsic angular momentum of localized electrons, this can give rise to the so-called ...

Phys.org / Record-energy neutrino may have begun its journey in blazars

Three years ago, in the waters of the Mediterranean Sea, the passage of an "ultra-energetic" cosmic neutrino was observed—the most energetic ever detected. The event drew international attention from the scientific community ...

Phys.org / 'Peculiar' crocodile ancestor started life on four legs before learning to walk on two

A "peculiar" ancient relative of the crocodile which experts believe began life on four legs before, in adulthood, it learned how to walk on just two has been revealed in a new study. Named Sonselasuchus cedrus, this archaic ...

Phys.org / Camera captures first video of a red fox attacking a wolf pup

We are used to seeing a strict order in nature, with apex predators at the top feeding on those lower down the pecking order. But in video footage from a nature reserve in Italy, we see a red fox turning the tables, attacking ...
