Without revenue from trophy hunting permits, conservation practices in some countries may ultimately be compromised, which could exacerbate biodiversity loss. Rather than banning big game hunting altogether, researchers suggest enforcing stricter regulations.
A second form of contagious cancer has been found in eight Tasmanian devils across southeastern Tasmania. This makes researchers question the rarity of transmissible cancers.
Male crickets emit a high-frequency chirp to startle potential female mates into revealing their location. This, researchers say, likely evolved from males impersonating predatory bats.
If the European Union lifted its ban on feeding pigs food waste, roughly 1.8 million hectares of threatened Brazilian forest and savannah could be saved from excess agricultural development.
The ancestry of modern Europeans' genetic make up has become somewhat clearer with the discovery of a previously unknown "fourth strand" of ancient hunter-gatherer ancestry.
The first-known European Christian church to have been built in the tropics was recently unearthed on one of the Cape Verde islands by archaeologists from the University of Cambridge. The island lies off the coast of West Africa and was once the heart of the Atlantic slave trade.
When cockroaches need to chew through tough materials they turn on muscled mandible boosters that supply them with super-charged chewing powers.
A new study by University of Cambridge and The Australian National University has found what are believed to be the oldest known stars. These luminous but ancient balls of gas bring into question our earlier ideas about how the galaxy formed.
Coughing deaths in the 4th and 3rd millennium B.C. were likely caused by the plague, which has been found in the dental DNA of skeletons from Eurasia.
Howler monkeys are fairly small animals, but can roar as powerfully as tigers. This ability comes at a evolutionary trade-off, though: howler monkeys with louder calls often have smaller reproductive organs, a recent study revealed.
After sequencing a genome of an ancient African male skull, researchers revealed more about the early humans' migration and introduction of farming in East Africa.
Lizards use bright colors to attract mates but this also makes their camouflage less effective, making them visible to predators, report researchers from the University of Cambridge.
Researchers from University of Cambridge and University of Colorado say that if active steps are taken by nations to decrease emissions from permafrost thaw in particular, this could reduce predicted emissions cost by $37 trillion. But that's not the case yet.
Jackdaws, a type of corvid, have been added to the list of 4 birds shown to recognize and recall faces. More on what they do with this information, here.
