Reptiles have a brain area previously suspected to play a role in mammalian higher cognitive processes, and establish its role in controlling brain dynamics in sleep.
The state of unified perception, which is characteristic of a conscious state in humans,...
Accurately predicting biodiversity loss from climate change requires a detailed understanding of what aspects of climate change cause extinctions, and what mechanisms may allow species to survive.
A new study by University of Arizona researchers presents detailed estimates of global...
Believed to have been pets at one stage in their evolution, the origins of the Australian dingo are shrouded in mystery, compelling generations of biologists to snoop for clues about their early history. New evidence has recently been revealed...
Half of the one million animal and plant species on Earth facing extinction are insects, and their disappearance could be catastrophic for humankind, scientists have said in a "warning to humanity".
"The current insect extinction crisis is deeply worrying," said...
It's no coincidence that some of the worst viral disease outbreaks in recent years -- SARS, MERS, Ebola, Marburg and likely the newly arrived 2019-nCoV virus -- originated in bats.
A new University of California, Berkeley, study finds that bats'...
Scientists said Monday they had discovered a new species of dinosaur closely related to Tyrannosaurus rex that strode the plain of North America some 80 million years ago.
Thanatotheristes degrootorum—Greek for "Reaper of Death"—is thought to be the oldest member...
Stories of unique and sentient interactions between elephants and their dead are a familiar part of the species' lore, but a comprehensive study of these interactions has been lacking—until now. A recent review of documented field observations of elephants...
When you were young, were you the type of child who would scour open fields looking for bumble bees? Today, it is much harder for kids to spot them, since bumble bees are drastically declining in North America and...
Methuselah, Adam, Jonah, Uriel, Boaz, Judith and Hannah—all sat dormant in Judea since biblical times. Now scientists have resurrected them in the hopes of better understanding their vanished lineage.
These seven ancient emissaries are date palm plants, now all growing in...
If you feed the birds in your backyard, you may be doing more than just making sure they have a source of food: you may be helping baby birds give parasites the boot.
New research published in the Journal of Applied...
When cuttlefish know that shrimp—their favourite food—will be available in the evening, they eat fewer crabs during the day. This capacity to make decisions based on future expectations reveals complex cognitive abilities.
"It was surprising to see how quickly the cuttlefish adapted...
