Phys.org / Are cats 'vegan' meat eaters? Why isotopic signatures of feline fur could trick us into thinking that way

Cats—unlike humans—are true carnivores: they must eat meat to survive because their bodies can't draw some essential nutrients from plants. By looking at tissues, researchers can get a good understanding of what foods ...

Phys.org / Innate biases of newborn animals inspire adaptive decision-making model

Precocial animals, the ones that move autonomously within hours after hatching or birth, have many biases they are born with that help them survive, finds a new paper led by Queen Mary University of London, published in Proceedings ...

Medical Xpress / Dementia research must include voices of those with lived experience

A new Canadian study has found that people living with dementia (PLWD) are often excluded from research due to assumptions of incapacity and variations in institutional processes. The authors argue that with rights-based, ...

Dialog / Infrared running of gravity offers a field-theoretic route to dark matter phenomena

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new particles, I propose ...
