Extinct swordfish-shaped marine reptile discovered

A team of international researchers from Canada, Colombia, and Germany has discovered a new marine reptile. The specimen, a stunningly preserved meter-long skull, is one of the last surviving ichthyosaurs—ancient animals ...

High-flying morpho butterflies evolved into efficient gliders

Some morpho butterflies live and fly high in the canopy of the Amazonian rainforest, and have evolved into highly-efficient gliding flyers. These results revealed by Wageningen University & Research and published in Science ...

How to read a jellyfish's mind

The human brain has 100 billion neurons, making 100 trillion connections. Understanding the precise circuits of brain cells that orchestrate all of our day-to-day behaviors—such as moving our limbs, responding to fear and ...

Loss of ancient grazers triggered a global rise in fires

From 50,000 years to 6,000 years ago, many of the world's largest animals, including such iconic grassland grazers as the woolly mammoth, giant bison, and ancient horses, went extinct. The loss of these grazing species triggered ...

Sun compass on demand

Monarch butterflies are famous for their annual long-distance migration, which takes them over several thousand kilometers from the north of the USA to their overwintering habitat in central Mexico. On their migration, the ...

Dopamine plays key role in songbird mating

In humans, the dopamine system has been tied to rewards and pleasurable sensations. As well as to memory and learning. A recent study from McGill University, published in Current Biology, suggests that dopamine may also play ...

How smart is an octopus?

The unique brainpower of octopuses—known for their intelligence and Houdini-like escapes—has been revealed by University of Queensland researchers.
