A new drug that prompts cancer cells to self-destruct while sparing healthy cells is now entering phase I clinical trials in humans. The drug, called PAC-1, first showed promise in the treatment of pet dogs with spontaneously occurring cancers, and is still in clinical trials in dogs with osteosarcoma.

Soil microbes known as rhizobia supply much-needed nitrogen to legumes such as clover (Trifolium species). In return, legumes shelter the rhizobia in nodules on their roots and provide them with carbon.

A group of international collaborators has found a way to deliver Ebola prevention information to people in every part of Sierra Leone - safely, and at negligible cost. The team is rolling out animated videos narrated in local languages that can be viewed on cell phones, tablets, computers and other digital devices.

Friend, foe or queen? Study highlights the complexities of ant perception

Researchers report that trap-jaw ants recognize the unique odor of a fertile queen only if the queen also shares the workers’ own chemical cologne – a distinctive blend of dozens of smelly, waxy compounds that coat the ants’ bodies from head to tarsus. The discovery offers new insights into how social animals evolved and communicate with others in their group, the researchers say.
