We can't know if or how animals understand death, but behavioral changes in some species could mean they experience something similar to human grief.

While many researchers are focusing on finding a difference in brains of people with dyslexia, some new research suggests it might not just be in their brains, but in their eyes.

Springtime means the arrival of green grass, bright flowers, and buzzing bees. But for many of us, it's also about sneezing, watery red eyes, and a runny nose, thanks to allergies. In this week's video, you'll learn why we get allergies,...
