The abundance of wild birds, fish, amphibians, reptiles and insects has drastically declined over the past 50 years, but the scale and seriousness of this loss is often lost when we focus on the number of species in an area
Did the ancient Greeks and Romans experience Alzheimer's? Medical texts from 2,500 years ago rarely mention severe memory loss, suggesting today's widespread dementia stems from modern environments and lifestyles, a new analysis shows.
Officials set up almost 2000 camera traps covering 120,000 square kilometres to estimate the number of snow leopards in India’s mountainous regions
Not only can parrots fly and walk, they can also swing along branches using their beaks, in a technique researchers are calling beakiation
Evolutionary biologists report they have combined PET scans of modern pigeons along with studies of dinosaur fossils to help answer an enduring question in biology: How did the brains of birds evolve to enable them to fly?

DNA analysis of spider webs from two locations in Australia identified dozens of vertebrate species, suggesting a new approach to wildlife monitoring
Calls made by male orangutans to attract females have short sequences nested inside longer sequences – a feature called recursion that was thought to be unique to human language
A previously unknown type of replicating agent named "obelisks” has been found in genomic data from stool samples – but we know little about what these entities do
A new study, which centers on evidence from skulls of a 6-million-year-old fossil ape, Lufengpithecus, offers important clues about the origins of bipedal locomotion courtesy of a novel method: analyzing its bony inner ear region using three-dimensional CT-scanning. The inner ear appears to provide a unique record of the evolutionary history of ape locomotion.

Drone footage filmed off the coast of California shows a 1.5-metre-long, entirely white great white shark pup, probably just hours old – something that has never been seen before
Experiments with a robotic dinosaur suggest feathers may have evolved to startle prey into fleeing from hiding places, a strategy used by some modern birds
Antechinus males only live for one breeding season, so they give up 3 hours of sleep a night during this short period before dying of exhaustion
Owls are famously good at rotating their heads, but now anatomical findings suggest they really could go a full 360 degrees without injuring themselves
Three fossils of Pachycormus fish from the dinosaur era feature smaller members of the same species in their guts - perhaps showing how the animals got by when food was scarce
DNA from ancient feces can offer archaeologists new clues about the life and health of Japanese people who lived thousands of years ago, according to a new study.

The brown bear is one of the largest living terrestrial carnivores, and is widely distributed across the Northern Hemisphere. Unlike many other large carnivores that went extinct at the end of the last Ice Age (cave bear, sabretoothed cats, cave hyena), the brown bear is one of the lucky survivors that made it through to the present. The question has puzzled biologists for close to a century -- how was this so?
