Detecting coral biodiversity in seawater samples

Researchers from the Okinawa Institute of Science and Technology (OIST) have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from ...

Graphene grows—physicists find a way to visualize it

Graphene is one of the strongest materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the ...

Super-dense packing of hydrogen molecules on a surface

Hydrogen (H2) is currently discussed as an ideal energy carrier of renewable energies. Hydrogen has the highest gravimetric energy density of all chemical fuels (141 MJ/kg), which is three times higher than gasoline (46 MJ/kg). ...

Referential alarm calls increase vigilance in brood parasite hosts

Yellow warblers are hosts to brood parasitic brown-headed cowbirds, which rely on other species to raise their offspring. Warblers use referential "seet" calls to warn female warblers specifically of the brood parasitic brown-headed ...

Scientists model Saturn's interior

New Johns Hopkins University simulations offer an intriguing look into Saturn's interior, suggesting that a thick layer of helium rain influences the planet's magnetic field.
