By recording grouper grunts for 12 years, scientists discovered major shifts in how red hind spawn and compete. Courtship calls once dominated, but territorial sounds have surged, suggesting changes in population structure. Machine learning helped decode the patterns quickly, offering a groundbreaking way to monitor and conserve reef fish.
Koala Stress Linked to Disease Threat
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.
Future Generations: NSF-Funded Project Explores How Nanoplastics are Transmitted to Offspring
You can’t see nanoplastics with the naked eye, but they’re everywhere — including your body.
Breaking Barriers in the Ice
For years, managing personal hygiene, particularly menstruation and toileting, in the extreme Antarctic environment was often a solitary and unspoken challenge, especially for women and non-binary individuals.
Student’s pinkie-sized fossil reveals a new croc species
A 95-million-year-old crocodyliform fossil, affectionately nicknamed Elton, was discovered in Montana by student Harrison Allen. Unlike most crocs, it lived on land and ate a varied diet. The find led to the naming of a new species, Thikarisuchus xenodentes, offering insights into croc evolution and burrow-based fossil preservation. For Allen,...
This vibrant moth fooled scientists for generations
For more than a century, a dazzling pink-and-yellow moth was mistaken for a common European species, but DNA analysis revealed it as entirely new: Carcina ingridmariae. Found across the eastern Mediterranean, this hidden beauty had evaded recognition until advanced barcoding techniques exposed its genetic secrets. Entomologist Dr. Peter Huemer confirmed...
Insects are disappearing from the last places we thought were safe
A long-term study in Colorado reveals that insect populations are plummeting even in remote, undisturbed areas. Over two decades, flying insect abundance dropped by more than 70%, closely linked to rising summer temperatures. The results suggest that climate change, not just human land use, is driving massive losses. Scientists warn...
This surprising building material is strong, cheap, and sustainable
A team at RMIT University has created a cement-free construction material using only cardboard, soil, and water. Strong enough for low-rise buildings, it reduces emissions, costs, and waste compared to concrete. The lightweight, on-site process makes it ideal for remote areas, while its thermal properties naturally cool buildings. Researchers see...
Ice Dissolves Iron Faster Than Liquid Water
Ice can dissolve iron minerals more effectively than liquid water, according to a new study from Umeå University. The discovery could help explain why many Arctic rivers are now turning rusty orange as permafrost thaws in a warming climate.
Heatwaves in US Rivers Increasing Up to Four Times Faster Than Air Heatwaves
As the frequency and intensity of heatwaves increase across the U.S., a similar but more striking phenomenon is occurring in American rivers.
