The thousands of pictures are among the oldest depictions of people interacting with the huge creatures, including mastodons. Usually the only clues about their appearance are skeletal remains.

The algae, known as peyssonnelid algal crusts (PAC), are taking over the reefs at such an aggressive rate that they are interfering with the ability of coral larvae to find places to settle on the reefs, and interfering with the reef’s natural ecosystem.

A new QUT-led study has found wild jaguars in the Amazon can cope with climate extremes in the short-term, but numbers will rapidly decline if weather events increase in frequency, diminishing sources of food.

Mongolia’s semi-arid plateau may soon become as barren as parts of the American Southwest due to a “vicious cycle” of heatwaves — that exacerbates soil drying, and ultimately produces more heatwaves — according to an international group of climate scientists.

Anthraquinones are a class of naturally occurring compounds prized for their medicinal properties, as well as for other applications, including ecologically friendly dyes.

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations.

Lithium-ion batteries (LIBs) that function as high-performance power sources for renewable applications, such as electric vehicles and consumer electronics, require electrodes that deliver high energy density without compromising cell lifetimes.

Four-​and-a-half billion years ago, Earth would have been hard to recognise.

Earlier this month a team of MIT researchers sent samples of various high-tech fabrics, some with embedded sensors or electronics, to the International Space Station.

Thomas Mnguni often woke to find the windows and floors of his home covered in a layer of black dust. Living between two coal mines and a landfill in Middelburg, South Africa, he and his family breathed some of the country’s most polluted air.
