Learning from experience is all in the timing

As animals explore their environment, they learn to master it. By discovering what sounds tend to precede predatorial attack, for example, or what smells predict dinner, they develop a kind of biological clairvoyance—a ...

What can worms tell us about human aging?

What can worms tell us about human ageing? A lot more than you'd think; as research led by the Babraham Institute but involving researchers from multiple disciplines drawn together from across the world has shown. In a cluster ...

A game of pool in the live cell

Cells need to react to environmental changes and maintain a balanced system of signaling cascades within the cell. Proteins outside of the cell, on the cellular surface, inside the cellular membrane, and within the cell orchestrate ...

CRISPR-based tool maps gene function in human cells

UC San Francisco scientists have used a high-throughput CRISPR-based technique to rapidly map the functions of nearly 500 genes in human cells, many of them never before studied in detail.

Secrets of a little-known cancer ally revealed

Human cancers often have a little recognized ally— the increased size and number of a cell's organelles called the nucleolus. The nucleolus is where ribosomes, the cellular protein factories, are made. Ribosomes can also ...

The Archean Ocean as an ideal breeding ground for life

In a project funded by the Austrian Science Fund FWF, the biochemist Markus Keller demonstrated successfully how important metabolic mechanisms were able to develop in cells four billion years ago. His research provides completely ...
