A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — ...

In vertebrate retinas, specialized photoreceptors responsible for color vision (cone cells) arrange themselves in patterns ...

Concepts encoded by concept neurons can be an animal, an article of clothing, a place, or a person. The concept can be evoked ...

Imagine a world where the oxygen you need changes dramatically between day and night. Your world shifts from being rich in oxygen (oxic) in the day, so you have energy to hunt for food, to ...

New research on the hippocampus, a brain area essential for memory, suggests that new rules of synaptic plasticity best explain how brain activity continually reshapes the way memories are recorded in ...

Made by combining several emerging technologies, human “bodyoids” could reduce animal testing, improve drug development, and alleviate organ shortages.

Meniscus tears are common knee injuries that have long frustrated patients and doctors due to limited repair options. A new ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants.

Plant behavior may seem rather boring compared with the frenetic excesses of animals. Yet the lives of our vegetable friends, ...

Scientists have identified a protein sensor in intestinal neurons that responds to pressure, inflammation to stimulate the ...
