This internal left-right asymmetry is believed to begin at the very early stage of development -- when a tiny embryo is divided into two parts during a process called gastrulation. This process ...

Many animals show signs of high intelligence, including strong memory, self-awareness and communication skills.

This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in ...

A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a ...

A research team at the Institut de Neurociències of the Universitat Autònoma de Barcelona (INc-UAB) has developed a new ...

Due to proteostasis stress induced by aging or disease, misfolded proteins can form toxic intermediate species of aggregates and eventually mature into less toxic inclusion bodies (IBs). Here, using a ...

The diagram below shows the same plant cell, as viewed with the light microscope, and with the transmission electron microscope. Animal and plant cells have certain structures in common.

Many cells in multicellular organisms are specialised. They have specific roles in the organism of which they are part. Their structure is adapted to their function. They are often grouped ...

The stability of Pt-based catalysts is critical to the reliability of proton exchange membrane fuel cells. Here, the authors use stroboscopic operando high energy X-ray scattering to reveal Pt ...
