Growth or immune response? Higher organisms must constantly balance these two priorities. As in humans, hormones regulate this balance in plants. Researchers at the Technical University of Munich (TUM) have discovered a mechanism ...

The sights and sounds of the Jurassic era are long gone, and we will never know for sure what that ancient world looked and sounded like. Fossils can offer clues, and reconstructions can give us a sense of the noises some ...

A recent study published in the Journal of Nutrition Education and Behavior explored elementary school teachers' experiences before and after the end of the federal universal free school meals (UFSM) policy. Researchers found ...

For many years, the European Union has pursued a policy aimed at the replacement, reduction and refinement of animal testing (the 3Rs principle). To put the ethical principle of the 3Rs into practice, the European Commission ...

In 1899, scientists began tracking avian migration by placing a small ring with an identifier around birds' ankles. Researchers then had to recapture the birds elsewhere, leaving the journey between those points a mystery. ...

Studies in the behavioral and brain sciences reporting a major sex-dependent effect—that a drug, treatment or other intervention is more effective in one sex than another—are supported by appropriate evidence less than 25% ...

A new study led by researchers at the University of California San Diego shows that the brain does not simply respond to breathing as a steady rhythm. Instead, the detailed shape of each individual breath is closely linked ...

In computer vision and robotics, ensuring that AI systems remain reliable under real-world conditions is a growing challenge. Deep neural network (DNN)-based vision systems are increasingly used in safety-critical applications ...
