Scientists discover new mechanism involved in learning and memory

What happens inside neurons when we memorize a password or learn the cello? Some of our basic understanding about learning and memory comes from the study of conditions in which cognitive development is disrupted. For example, ...

Observing the secret life of molecules inside the cell

To understand how cells function, scientists study how their different components—from single molecules to multiple organelles—work together. Using traditional structural biology techniques, they can look at individual ...

Live cell DNA architecture in real time

Inside the nucleus of a human cell, there are approximately two meters of DNA folded into a multi-layered 3D structure called chromatin, which allows all of our genetic information to be compacted into a tiny little space.

A missing genetic switch at the origin of embryonic malformations

Embryonic development follows delicate stages: For everything to go well, many genes must coordinate their activity according to a very meticulous scheme and tempo. This precision mechanism sometimes fails, leading to more ...

Gene repression can be sex-specific

Researchers have shown for the first time that embryonic cells destined to become either egg or sperm rely on different methods of repressive gene regulation.

Researchers call for standards for biological imaging

Stained molecules in the cell nucleus, the inner life of a synaptic cleft, or the surface of a floral leaf: Modern microscopes enable researchers to examine processes that are otherwise invisible and located in tiniest structures ...
