Caspian tigers were some of the largest cats ever to roam the Earth, but they went extinct in the 1960s. Now, some scientists want to bring them back. A new study, published in the journal Biological Conservation, lays out the plan...
One of the most talked about biological breakthroughs in the past decade was the discovery of the genome editing tool CRISPR/Cas9, which can alter DNA and potentially remove the root causes of many hereditary diseases. Originally found as part of...
When it comes to hookups in the animal world, casual sex is common among chimpanzees. In our closest animal relatives both males and females mate with multiple partners. But when taking the plunge into parenthood, they're more selective than...
In the upside-down world of the pipefish, sexual selection appears to work in reverse, with flashy females battling for males who bear the pregnancy and carry their young to term in their brood pouch. But new research shows even...

Suburban development is forcing some songbirds to divorce, pack up and leave and miss their best chances for successful reproduction. As forested areas increasingly are converted to suburbs, birds that live on the edge of our urban footprint must find...
Chickens are not as clueless or "bird-brained" as people believe them to be. They have distinct personalities and can outmaneuver one another. They know their place in the pecking order, and can reason by deduction, which is an ability that...
In the warm summer months, bats go about their business each night, flying and gobbling up insects (a benefit to us). Using echolocation (making calls and listening for returning echoes to figure out where objects are) they can hunt...
Baby reef fish have an internal magnetic 'compass' that directs them home at night, world-first research has revealed. Professor Mike Kingsford from the ARC Centre of Excellence for Coral Reef Studies at James Cook University collaborated with colleagues in Germany...
The world's fastest land animal, the cheetah (Acinonyx jubatus), is sprinting towards the edge of extinction and could soon be lost forever unless urgent, landscape-wide conservation action is taken, according to a study published today in the journal Proceedings...
