When it comes to the battle between tiny rodents known as Brandt’s voles and carnivorous birds called shrikes, the birds may seem to have all the advantages. Shrikes, or butcherbirds, are capable of killing small animals like mice and lizards with a paralysis-inducing beak pinch to the spinal cord followed by vigorous shaking to break the prey’s neck. But new research shows the voles can fight back—by making their habitat a safe space.

In the summer of 2019, Dominique Potvin, an animal ecologist at the University of the Sunshine Coast in Australia, was excited to begin a tracking study on Australian magpies. She and her team had an exciting new technology to test out and plenty of research questions about the birds’ movements and social dynamics.

But the magpies had other ideas. Within minutes of being fitted with tiny, backpack-like tracking devices, the birds began showing evidence of cooperative “rescue” behavior to help one another remove the trackers.

To assess grief in pet dogs and their owners, researchers conducted a survey of people who had owned at least two dogs, one of whom died while the other was still alive. They found that both a friendly relationship between the two dogs and the owner’s grief increased the likeliness of negative behavioral changes in surviving dogs. The researchers say that negative behavioral and emotional changes observed in surviving dogs could be due to both a grief-like reaction in response to the loss of their companion and a reaction to the grief of their owners.

For the first time, researchers observed wild chimpanzees applying insects to their own wounds and the wounds of others. Although questions remain, the topical application of these insects appears to be an instance of self-medication.

Scientists in all fields use a dynamic, open-ended process to investigate questions, known as the scientific method. This is a logical, problem-solving approach to discovering answers that are supported by evidence.

The scientific method is essential because it provides an objective, standardized approach to conducting experiments. Using the scientific method limits the influence of biases and preconceived notions and improves the quality of results.
