More than a decade of acoustic recordings of grouper grunts are providing new insight into how sound can be used to monitor and manage vulnerable fish populations. The research by Florida Atlantic University’s Harbor Branch Oceanographic Institute focused on the red hind (Epinephelus guttatus), a commercially important Caribbean grouper species. Red hind are protogynous hermaphrodites,…

Australian researchers have revealed a clear relationship between stress and increased disease risk in koalas in South East Queensland and on the New South Wales North Coast. A study led by Dr Michaela Blyton at The University of Queensland measured and tracked the level of koala retrovirus (KoRV) in groups of captive and wild koalas….

As infants, humans naturally learn new words and their associations — like the fact that forks are related to bowls because both are used to consume food. In a study published in the Cell Press journal Current Biology on September 18, a team of animal behavior experts demonstrate that dogs can categorize objects by function,…

Diamonds from South Africa’s Voorspoed mine have revealed the first natural evidence of nickel-rich metallic alloys forming deep in Earth’s mantle, between 280-470 km (174-292 miles). A new study reveals that these inclusions coexist with nickel-rich carbonates, capturing a rare snapshot of a “redox-freezing” reaction whereby oxidized melts infiltrate reduced mantle rock. The growing diamond…
