By counting the number of cancer-fighting immune cells inside tumors, scientists say they may have found a way to predict survival from ovarian cancer. The researchers developed an experimental method to count these cells, called ...
A mathematical pattern of movement called a Lévy walk describes the foraging behavior of animals from sharks to honey bees, and now for the first time has been shown to describe human hunter-gatherer movement as well. The study, led ...

Researchers say they've discovered why infants who live in homes with a dog are less likely to develop asthma and allergies later in childhood. The team conducted experiments with mice and found that exposing them to dust from homes where ...
New brain research suggests one reason girls mature faster than boys during their teen years. As people age, their brains reorganize and reduce connections. In this study, scientists examined brain scans from 121 healthy people, aged 4 to ...
