Unprecedented wave of large-mammal extinctions linked to prehistoric humans

Homo sapiens, Neanderthals and other recent human relatives may have begun hunting large mammal species down to size -- by way of extinction -- at least 90,000 years earlier than previously thought, says a new study published in the journal Science.

Elephant-dwarfing wooly mammoths, elephant-sized ground sloths and various saber-toothed cats highlighted the array of massive...

Dogs could be more similar to humans than we thought

Dog and human gut microbiomes have more similar genes and responses to diet than we previously thought, according to a study published in the open access journal, Microbiome.

Dr Luis Pedro Coelho and colleagues from the European Molecular Biology Laboratory, in collaboration with Nestlé Research, evaluated the gut microbiome of two dog breeds and found that...

New ant species from Borneo explodes to defend its colony

Amongst the countless fascinating plants and animals inhabiting the tropical rainforests of Southeast Asia, there are the spectacular "exploding ants," a group of arboreal, canopy dwelling ants nicknamed for their unique defensive behaviour.

When threatened by other insects, minor workers can actively rupture their body wall. Apart from leading to the ants' imminent death, the "explosion"...

Optogenetic study shows that male flies find ejaculation pleasurable

Researchers reporting in Current Biology on April 19 show that male fruit flies find sex -- and more specifically ejaculation -- to be an inherently rewarding experience. The study is the first to show that the rewarding nature of ejaculation is conserved among animals, from flies and mammals. It also adds to evidence that manipulating...

Better species mapping can improve conservation efforts

The scientific models that ecologists and conservation biologists rely on to determine which species and habitats to protect lack critical information to help them make effective decisions, according to a new study.

Angela Strecker, an environmental science professor at Portland State University and the study's co-lead author, said that species distribution models can help predict all...
