It's time to stop bickering, accept what science tells us, acknowledge the widespread occurrence of intentional behavioral flexibility, and pay attention to why it has evolved.

Microplastics and nanoplastics are increasingly recognized as pervasive environmental contaminants that accumulate in animals ...

Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger ...

Advances in organ and computer models are raising the prospect that some animal experiments could be eliminated. But there ...

BrainAlignNet, AutoCellLabeler, and CellDiscoveryNet—to automatically track and identify neurons in moving worms and jellyfish.

Understanding the connection between behavior and brain cell activity is a major goal of neuroscience. To make progress, ...

Our analysis showed that temporal perception has even greater variation than scientists may have realised. Our perceptual ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

The way Dr. Paul Niehans, a stony-faced, ramrod-straight Swiss physician told it, his theory and practice of “cellular therapy” sounded plausible enough. Thirty years ago he had begun transplanting ...

Vacuoles and lysosome-related organelles (LROs) are essential compartments in eukaryotic cells playing crucial roles in storage, degradation, signaling, and homeostasis. Despite their functional ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...
