Red foxes and Arctic foxes dive headfirst into snow at up to 4 metres per second to catch small rodents, and the shape of their snouts reduces the impact force
Dinosaurs were likely as smart as reptiles but not as intelligent as monkeys.

Commercial bowhead whaling ended in the early 20th century, but the industry’s lasting effects on the whales’ genetic diversity are leading to declines again
Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor where a ballcourt was built.
When alpacas mate, males deposit sperm directly into the uterus, a reproductive strategy not confirmed in any other mammals
The neurons in wasp brains that help them recognise hive mates are similar to those in the brains of primates, including humans
Intensive breeding since the 19th century has created thousands of varieties of rose, but a reduction in genetic diversity could leave them vulnerable to diseases and climate change
Oncorhynchus rastrosus, a giant species of salmon that lived in the North American Pacific Northwest a few million years ago, sported a pair of front teeth that projected out from the sides of its mouth like tusks, according to a new study.
Targeted culling of crown-of-thorns starfish has resulted in parts of the Great Barrier Reef maintaining and even increasing coral cover, leading researchers to call for the programme to be dramatically scaled up
Using genomic data from more than 9500 species, biologists have mapped the evolutionary relationships between flowering plants
A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today.

A set of large, distinctive footprints suggest a raptor dinosaur that lived in East Asia 96 million years ago grew to a length of 5 metres
Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years.
Six full-body fossils of Ptychodus sharks have been formally analysed for the first time, revealing that they were fast swimmers that preyed on shelled creatures
Palaeontologists have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts -- it's all down to their skin. Palaeontologists studied 45-million-year-old fossil frogs from the Geiseltal site in central Germany. Remarkably, the fossils show full body outlines of the soft tissues. The team discovered that the excellent condition of the fossil frogs is due to preservation of ancient skin remnants.

A group of around 40 scientists signed a declaration calling for formal acknowledgement of consciousness in a range of animals, including insects and fish – but the evidence is still lacking
